Pengolahan Fraksi Solar Hasil Pirolisis Sampah Plastik Menggunakan Adsorben Zeolit Teraktivasi Asam Sulfat
type: item
description: Processing plastic waste, especially Low-Density Polyethylene (LDPE), is an environmental problem because it is difficult to decompose. One method of processing plastic waste is pyrolysis, which converts plastic into liquid fuels such as diesel. However, pyrolyzed diesel still contains impurities, such as sulfur, chlorine, and hydrocarbon compounds, which affect fuel quality, including acid number and viscosity. This study aims to determine the adsorbent characteristics of natural zeolite (ZA), chemically-physical activation zeolite (ZKF), and physico-chemical activation zeolite (ZFK), and to assess their effectiveness in improving the quality of diesel fuel from the pyrolysis of plastic waste. The test of zeolite as an adsorbent was conducted by measuring water and ash content and by characterizing it using Fourier Transform Infrared (FTIR), X-Ray Fluorescence (XRF), and a Gas Sorption Analyzer (GSA). FTIR results showed spectral changes indicative of the loss of OH groups and revealed the main functional groups of the activated zeolites. XRF results show that ZKF and ZFK have increased silica (SiO₂) content from 81.85% to 82.19% and 82.26%, and decreased iron oxide (Fe₂O₃) content from 0.94% to 0.63% and 0.62%. GSA analysis showed increases in the surface areas of ZKF and ZFK from 11.49 m²/g to 34.06 m²/g and 19.78 m²/g, respectively. Processing of pyrolyzed diesel using ZKF and ZFK showed a decrease in acid number from 1.03 mg NaOH/g to 0.25 mg NaOH/g and 0.20 mg NaOH/g, a reduction in viscosity from 5.45 cSt to 5.19 cSt and 5.13 cSt. The most effective adsorbent for reducing acid number and viscosity is ZFK, with a surface area of 19.78 m2/g, an average pore diameter of 5.99 nm, and optimal adsorption conditions at a stirring time of 4 minutes with an adsorbent mass of 1.5 grams in 50 mL of pyrolyzed diesel.

Analisis Status Mutu Sungai Pawan di Kabupaten Ketapang Berdasarkan Metode STORET
type: item
description: The Pawan Watershed (DAS Pawan) is one of the main watersheds in Ketapang Regency, West Kalimantan Province, serving as an essential water source for community needs while receiving pollutant loads from residential areas, plantations, agricultural activities, and palm oil industries. Pollution pressure increases due to the discharge of domestic wastewater, runoff from plantation areas, and various industrial activities. This study aims to identify pollution sources in the Pawan River, assess its water quality, and analyze its status using the STORET method. This research is a quantitative descriptive study that provides an overview and explanation of pollution sources, water quality characteristics, and the water quality status of the Pawan River. The data used in this study are secondary data obtained from the Environmental and Forestry Agency of West Kalimantan Province for the period 2021-2024, covering 10 monitoring points. The analyzed water quality parameters include pH, TSS, BOD, COD, DO, nitrate, phosphate, and fecal coliform, in accordance with the Class II water quality standards set out in Government Regulation No. 22 of 2021. The results of the inventory indicate that pollution sources originate from residential activities and palm oil industries (point sources) as well as plantations and fields (non-point sources). The highest recorded values were 12,9 mg/L for BOD in Semester II, 125 mg/L for COD in Semester I, and 0,3 mg/L for phosphate in Semester II, all of which exceeded the water quality standards. Based on the STORET method, the water quality status of the Pawan River is heavily polluted at monitoring point X, with a score of -34 in Semester II.

Pengolahan Limbah Cair Industri Sablon dengan Metode Elektrokoagulasi
type: item
description: Wastewater from the screen-printing process contains concentrated dyes and heavy metals, such as hexavalent chromium (Cr⁶⁺), which are hazardous to the environment if discharged untreated. Electrocoagulation is a treatment method that uses an electric current to dissolve a metal electrode, which then reacts to form coagulants within the water. These coagulants bind and precipitate contaminant particles, such as dyes and heavy metal ions. This study aims to (1) determine the efficiency of the electrocoagulation method in reducing color and Cr⁶⁺ parameters; (2) analyze the effect of contact time variation; (3) determine the electrode lifespan; and (4) calculate the estimated energy consumption and cost. The process was conducted using an Iron (Fe) anode and an Aluminum (Al) cathode at a constant voltage of 12 V, with contact times of 30, 45, and 60 minutes. The results showed that the electrocoagulation process was significantly effective (p < .001) in improving wastewater quality. The process successfully reduced color with an efficiency exceeding 99% and Cr⁶⁺ concentration with an efficiency over 92%, while also significantly increasing the solution's pH. Analysis of variance (ANOVA) indicated that variation in contact time had a significant effect on pH (p = 0.024). However, extending the time from 30 to 60 minutes did not show a statistically significant effect on the removal efficiency of color (p = 0.156) or Cr⁶⁺ (p = 0.270), indicating that the null hypothesis (H₀) was accepted for these two parameters. Electrode dissolution efficiency ranged from 64.5% to 75.6%, and the lowest estimated energy cost was obtained at the 30-minute treatment, at IDR 31.36 per liter. This study concludes that electrocoagulation with an Fe anode and Al cathode is highly effective, and a 30-minute process duration is optimal for achieving high pollutant removal efficiencies of 99.43% for color and 99.47% for Cr⁶⁺ cost-effectively. Electrocoagulation has been proven effective and is p…

Kajian Konsumsi Bahan Bakar Dump Truck pada Pengangkutan Ore Bauksit di PT. Antam Tbk UBP Bauksit Tayan, Kalimantan Barat
type: item
description: In mining operations, mechanical equipment is essential. One of the mechanical pieces of equipment used in the hauling process, particularly in the open-pit mine of PT ANTAM Tbk UBPB Tayan, is the dump truck. A crucial component of the hauling activity is the fuel required by the hauling equipment. This study aims to determine the fuel consumption (liters/hour) of the hauling equipment and to analyze the fuel costs incurred during the transportation of bauxite ore. Several factors, including road grade, influence fuel consumption. Based on field observations, 4 out of 17 road segments exceeded the company's recommended maximum road grade of 10%. Other factors affecting fuel consumption include idle time, rimpull usage, power, and operator behavior towards the hauling equipment. The fuel consumption was calculated using rimpull and idle RPM. Based on rimpull and idle RPM calculations, the fuel consumption of the Hino 500 dump truck is 8.71 liters/hour, with a fuel cost of IDR 134,850/hour. The hauling equipment productivity is 70.23 tons/hour, resulting in a fuel ratio of 0.12 liters/ton and a hauling cost of IDR 1,860 per ton. After simulating improvements in road grade and idle time, fuel consumption decreased to 7.39 liters/hour, with a fuel cost of IDR 114,545/hour. The productivity of the hauling equipment after idle time improvement increased to 93.56 tons/hour, resulting in a post-improvement fuel ratio of 0.08 liters/ton and a hauling cost of IDR 1,240 per ton.

Analisis Tingkat Bahaya Erosi di Sub DAS Manday
type: item
description: Erosion is the process by which soil particles are detached and transported from their original location to other areas, primarily driven by water and wind, through the breakdown of soil aggregates (dispersion) and surface runoff. Continuous erosion can lead to sedimentation in rivers, reducing their capacity to carry water and increasing the risk of flooding during periods of high rainfall. However, scientific studies on erosion in the Manday sub-watershed remain limited. This study aims to analyze the extent of erosion occurring in the Manday Sub-Watershed using the Universal Soil Loss Equation (USLE) method combined with Geographic Information Systems (GIS), classify the erosion hazard level (EHL) in the Manday Sub-Watershed, and produce a map of the distribution of erosion hazard levels (EHL) in the Manday Sub-Watershed. The parameters used include the erosivity factor (R), soil erodibility (K), slope length and gradient (LS), land cover (C), and land conservation measures (P). The results of the study show that erosion in the Manday Sub-Watershed amounts to 101,491.44 tons/ha/year, with five erosion hazard levels (EHL) classified: very low, low, moderate, high, and very high, with the very low category covering 176,966.41 ha (56.95%) and the low category covering 92. 773.49 ha (29.86%), while the moderate category accounted for 5.67% (17,618.21 ha), severe for 3.35% (10,397.92 ha), and very severe for 4.17% (12,971.30 ha). Mapping the distribution of erosion hazard levels (TBE) shows that areas with higher TBE are generally on steep slopes with minimal vegetation cover. This mapping underscores the need for targeted land management in high-risk areas to mitigate erosion impacts.

Analisis Blending Bauksit Menggunakan Metode Simplek Di PT. Bumi Khatulistiwa Bauksit Kecamatan Meliau Kabupaten Sanggau, Kalimantan Barat.
type: item
description: PT conducted the blending calculations. Bumi Khatulistiwa Bauksit has not yet yielded efficient results. In terms of grade, the blending results exceed the company's specifications. Regarding tonnage, the company uses only a small amount of ROM, so it cannot fully maximize ROM with low-grade material. The research aims to optimize ROM with Al2O3 levels below 46% that are not selling well, thereby maximizing both grade and tonnage. The study calculates the blending activities in a barge with a capacity of 9.500 tons. Blending uses a 3-ROM composition and is simulated in blending activities using the simplex method to achieve optimal tonnage, in line with customer-grade requirements. The blending calculation results for bauxite using the simplex method show ROM 03 at 3.790,84133 tons, ROM 06 at 3.451,05238 tons, and ROM 12 at 2.248,10629 tons, with Al2O3 at 46,171%, SiO2 at 12%, and RSiO2 at 4%.

It aims to (1) identify the main technical constraints in waste collection and processing in Pariaman; (2) assess public awareness and practices related to waste separation and disposal; (3) examine inter-agency coordination in supporting the implementation of waste-management policies. This is a qualitative case-study research and was conducted in Pariaman over ten months (February–November 2025). The informants were 4 persons selected through purposive sampling. Research instruments comprised semi-structured interview guides, observation checklists, and documentary evidence. Data were collected through in-depth interviews, participatory observation at the Tungkal Selatan landfill and related facilities, and document review. The findings indicate that, from a technical perspective, waste management in Pariaman falls into the “adequately compliant” category (mean score 75%). From a social perspective, public understanding of waste separation is relatively reasonable, classified as “compliant” (mean score: 81.5%). Institutionally, governance demonstrates adherence to standard operating procedures and coordination forums, which are also classified as “compliant” (mean score 82%). The study concludes that effective waste-management mitigation requires an integrated intervention comprising fleet renewal and scheduled maintenance, digitalization of operational systems, strengthening of technical capacity and community cadres, and clarification of authority alongside consistent inter-organization enforcement mechanisms. Recommendations are directed to Disperkim LH to develop an integrated operational plan, to the community to reinforce separation practices and participation in local waste banks, and to city policymakers to establish sustainable financing mechanisms, clarify institutional mandates, and implement more consistent enforcement procedures.

Analisis Kapasitas Sistem Drainase Parit Keramat di Kawasan Bandar Udara Supadio Kabupaten Kubu Raya Menggunakan HEC-RAS
type: item
description: Supadio Airport has several drainage channels, including the Parit Keramat Drainage Channel. This channel has experienced narrowing due to household waste accumulation and sedimentation, leading to flooding in 2017 when the airport area was hit by extreme rainfall and high tides. As a result, 12 flight schedules were cancelled, and 36 flights were delayed (Kompas, 2017). To address this issue, an effective drainage system is necessary, especially in the runway, taxiway, and apron areas, to maintain aviation safety and security. The flood condition at Supadio Airport was analyzed using technical calculations and unsteady-flow simulations for a 10-year return period, based on tidal data calibration and instantaneous discharge in HEC-RAS. The drainage network in the study area was modeled based on topographic measurements of the existing channels. The Parit Keramat Channel is approximately 1,400 meters long. The HEC-RAS modeling results for the 10-year return period and tidal conditions show a significant impact on the existing channel condition. Most of the STAs (Stations) on the Parit Keramat Channel experienced flooding, with inundation heights ranging from 0.03 to 0.38 meters.

Kinetika Adsorpsi Antibiotik Tetrasiklin Oleh Komposit TiO2-Ni/PVA/Serat Sabut Pinang Teraktivasi
type: item
description: Environmental pollution from tetracycline antibiotics has become a serious concern because of their stability and tendency to bind to Ca2+ and other ions, leading to frequent detections in wastewater, surface water, groundwater, sludge, and sediments. One effective method to address this issue is adsorption using TiO2-Ni-based composite materials. This study aims to investigate the effect of variations in polyvinyl alcohol (PVA) mass on the adsorption capacity and rate of tetracycline in TiO2-Ni/PVA/activated areca fiber composites. TiO2-Ni/activated areca fiber was composited with PVA at mass ratios of 1, 2, and 3 and then tested in a tetracycline solution for 5 hours. Kinetic data were analyzed using first-order, second-order, pseudo-first-order, and pseudo-second-order models. The results showed that increasing PVA mass enhanced the adsorption percentage, with the highest value observed at 3 grams of PVA, reaching 12.60% after 5 hours of contact. The kinetic pattern of TiO2-Ni/PVA/activated areca fiber composites with 1 and 2 grams of PVA followed the pseudo-first-order adsorption model. In contrast, the composite with 3 grams of PVA tended to follow the first-order adsorption model.

Pengolahan Air Sumur Menggunakan Limbah Cangkang Telur Ayam Sebagai Biokoagulan Dalam Penurunan Logam Besi (Fe) dan Kekeruhan
type: item
description: Clean water is essential for human life; however, its distribution in Kubu Raya Regency remains limited, prompting residents to rely on dug wells as their primary water source. In the Hosana Fhileo residential area, groundwater quality exceeds permissible limits, with iron (Fe) concentration at 14.41 mg/L and turbidity at 288 NTU, surpassing the standards set by the Indonesian Ministry of Health Regulation No. 2 of 2023. Concurrently, the abundance of eggshell waste offers potential for its use as a natural coagulant due to its calcium carbonate (CaCO₃) content. This study aims to evaluate the effectiveness of eggshell powder as a coagulant in reducing iron concentration and turbidity in groundwater, and to compare it with the chemical coagulant Poly Aluminium Chloride (PAC). Laboratory-scale jar tests were conducted in two stages: the first used eggshell powder at 30, 50, and 70 g/L, while the second used PAC at 60, 70, and 80 g/L. Results showed that a 70 g/L dose of eggshell powder reduced iron concentration by 34.52% to 9.44 mg/L (p = 0.003 < 0.05) and turbidity by 90.61% to 27.05 NTU (p = 0.002 < 0.05). In contrast, a 60 g/L PAC dose increased iron levels to 16.32 mg/L (p = 0.002 < 0.05), but reduced turbidity by 84.57% to 44.43 NTU (p = 0.001 < 0.05). These findings indicate that eggshell powder is a promising eco- friendly coagulant. However, its Fe removal efficiency may be improved through process optimization, such as pH adjustment to enhance coagulation performance.

Pengelolaan Air Limbah pada Proyek Konstruksi: Tinjauan Sistem Zero Liquid Discharge
type: item
description: Wastewater management in construction projects is a strategic issue in supporting sustainable development. The Zero Liquid Discharge (ZLD) system has emerged as an innovative solution to eliminate liquid effluents through water recovery and solid utilization. This study employs a literature review approach, covering scientific publications from 2016–2025, to identify the efficiency, technical challenges, and policy implications of ZLD implementation in the construction sector. The findings show that ZLD can recover 85–98% of wastewater, producing water that meets reuse standards for non-potable purposes such as equipment cleaning, concrete curing, and dust suppression. System efficiency is influenced by wastewater characteristics, technological configuration, and energy sources, with specific energy consumption ranging from 5 to 12 kWh/m3. Life Cycle Assessment (LCA) analysis indicates that ZLD reduces water pollution by up to 95%, but may increase carbon emissions by around 20% if low-carbon energy is not used. Strategically, ZLD integration requires supportive green policies, sustainable financing, and the adoption of circular-economy principles to accelerate the transition to green construction.

type: item
description: Singkawang City is one of the cities frequently visited by domestic tourists in West Kalimantan Province. The need for space for built-up land and urban infrastructure continues to increase along with population growth. This phenomenon will reduce urban vegetation area, thereby allowing urban emissions to continue to grow. For this reason, developing green open spaces as a bioengineering technique and creating relatively cheaper, healthier, safer, and more comfortable biofilters are necessary. The purpose of this study is to analyze the need for public green open spaces based on area and population using the overlay method, and to digitize the distribution map of existing green open spaces in Singkawang City. Based on the results and discussions in this study, it can be concluded that the area of public green open space needed in Singkawang City is 791.12 Ha, and the City still lacks 476.98 Ha of public green open space. Meanwhile, the need for public green open space per capita in West Singkawang District from 2025 to 2035 has been met by an existing public green open space area of 175.6 Ha. In Central Singkawang District, from 2025 to 2028, there was an existing public green open space of 159.69 Ha, but from 2029 to 2035, there was a shortage of public green open space of 15.09 Ha

Evaluasi Unit Instalasi Pengolahan Air (IPA) Miniplant Dago Pakar Perumda Tirtawening Kota Bandung
type: item
description: Established in 1986, the Dago Pakar Miniplant is a compact Water Treatment Plant (WTP) operated by Perumda Tirtawening, the municipal water utility of Bandung City, with raw water intake from Pakar Pond and a designed production capacity of 50 liters per second. This study assesses the adequacy of water quantity, the continuity of supply, the quality of both raw and treated water, and the operational performance of the treatment units at the Dago Pakar Miniplant IPA. The findings indicate that the plant currently supplies only 13.7 liters/person/day, which is far below the minimum basic drinking water requirement of 60 liters/person/day stipulated in the Regulation of the Minister of Home Affairs of the Republic of Indonesia Number 71 of 2016. Regarding service continuity, the system is currently operating for 21.91 hours per day, so it has not yet achieved the expected continuous 24-hour operation. Laboratory analysis of raw water shows that 15 parameters, color, BOD₅, COD, DO, nitrite, ammonia, fluoride, free chlorine, iron, manganese, zinc, total detergent, phenol, fecal coliform, and coliform, do not comply with the quality standards specified in Government Regulation Number 22 of 2021. For production (treated) water, three parameters, namely iron, manganese, and residual chlorine, also fail to meet the drinking water quality requirements set out in the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. These deviations from standard are closely related to several installation units whose condition and configuration are no longer aligned with the original design criteria, ultimately undermining Miniplant Dago Pakar's ability to consistently meet the prescribed standards for water quality, quantity, and continuity.

Identifikasi Kandungan Organik Dan Logam Berat Sekitar Pabrik Kelapa Sawit Dan Area Bekas Tambang Emas di Sub Das Seminis
type: item
description: Water quality is a key factor in maintaining ecosystem balance, public health, and the sustainability of the agricultural and industrial sectors. In Sambas District, particularly in the Seminis Sub-watershed, water quality degradation has become a crucial issue, driven by illegal gold mining and the expansion of oil palm plantations, which generate hazardous waste, including mercury, as well as industrial wastewater. This study aims to identify water quality characteristics in the Seminis sub-watershed and analyze the influence of various pollutant sources, particularly from illegal gold mining and oil palm plantations. The research method included surface water sampling at four representative points representing variation in pollutant sources: former mining land, the palm oil mill WWTP outlet, the plantation area, and the settlement. Physical (TSS), chemical (pH, BOD, COD, total nitrogen), and heavy metal (mercury) parameters were analyzed in accordance with national standards and government regulations. The results showed that most water quality parameters remained below the class II quality standards, except for BOD and COD at several points, which exceeded the thresholds due to organic pollutant loads from industrial and agricultural waste.
