Abstract

The catfish farming industry is an industry that uses a lot of water for its production process, so the amount of waste produced is quite large. Waste from fish farming activities generally results from the accumulation of leftover feed used for catfish consumption and the excretion results of the fish being kept. Waste produced from fish farming activities contains organic material in the form of particles. The aim of this research is to analyze the quality of waste water produced in catfish cultivation in terms of the water quality parameters in freshwater fish cultivation SNI 7550:2009, and the efficiency produced in processing liquid waste using the anaerobic method with bamboo media. This research uses the Anaerobic Processing method with bamboo media. Water samples are taken using the grab sampling method. The area studied is the residential scale catfish farming industry. The quality of wastewater discharged from catfish farming, most parameters such as dissolved oxygen (DO), Cadmium (Cd), Lead (Pb), ammonia (NH3), and nitrite (NO2-) do not meet the quality standards specified in SNI 7550: 2009. The anaerobic method significantly succeeded in reducing the concentration of ammonia (NH₃) with an efficiency of 83% and nitrite (NO₂⁻) with an efficiency of 89%, showing efficiency in reducing nitrogen compounds that are harmful to aquatic ecosystems

Abstract

Karawang Regency, as an area experiencing rapid population growth and industrial development, faces serious challenges in the provision of clean water. This study aims to project the clean water demand in Karawang Regency up to the year 2044 using a quantitative descriptive method and an exponential projection model. The data used include population figures, clean water customer data, and the volume of water sold by Perumdam Tirta Tarum. The projection results indicate a significant increase in clean water demand from 898,17 liters/second in 2024 to 7.970,48 liters/second in 2044. This increase is driven by population growth, expanded service coverage, and the development of non-domestic sectors. The results of this study are expected to serve as a basis for sustainable clean water supply system planning in Karawang Regency.

Abstract

Clean water access remains a significant challenge in Pontianak City despite high annual rainfall exceeding 3,000 mm. This study aims to design a rainwater harvesting system (RWH) as an alternative source of clean water for the Faculty of Engineering at Universitas Panca Bhakti (UPB). The research employed a mixed-method approach, including field surveys, technical analysis of roof catchment potential, water quality assessment, system design, and financial feasibility using Net Present Value (NPV) and Benefit-Cost Ratio (BCR). The results showed that the building's roof area (571 m ²) with 80% system efficiency could harvest approximately 1,281.32 m ³/year of rainwater, meeting only 18.34% of the building's clean water demand. Due to low pH and nitrate/nitrite contamination, the proposed treatment system includes sand-carbon-zeolite filtration and UV sterilization. Financially, the project resulted in a BCR of 0.76, indicating it is not yet economically viable on its own. However, the system supports UPB's Green Campus 2027 vision by contributing to flood risk reduction, groundwater conservation, and operational efficiency. Future integration with hybrid systems is recommended to enhance sustainability and water resilience on campus.

Abstract

Contaminated soil with heavy metal lead (Pb) can be remediated using environmentally friendly biological technologies, one of which involves the use of earthworms (Lumbricus rubellus). This study aimed to evaluate the ability of Lumbricus rubellus as a bioaccumulator of lead during the vermicomposting process of contaminated soil. The vermicomposting experiment was conducted under aerobic conditions for 56 days with observations made every 14 days (on days 0, 14, 28, 42, and 56) at a laboratory scale. The study consisted of two experimental variations: Reactor A, which contained a 1:1 ratio between contaminated soil and organic vermicomposting materials (cow manure and cabbage waste), and Reactor B, with a 1:2 ratio. Each reactor was inoculated with 75 adult Lumbricus rubellus earthworms weighing approximately 0.70"“0.75 grams. The primary parameter observed was the concentration of lead in the earthworm tissues, measured using Atomic Absorption Spectrophotometry (AAS). The results showed the highest lead accumulation in Reactor A, increasing from 30.31 mg/kg on day 0 to 92.51 mg/kg on day 56, representing a 204.6% increase. These findings demonstrate that Lumbricus rubellus has significant potential as a bioaccumulator agent for reducing lead contamination through the bioaccumulation mechanism during vermicomposting. This supports the application of environmentally friendly biological technology for the rehabilitation of lead-contaminated land.

Abstract

The national waste generation in 2024 reached 19.57 million tons per year, yet only around 46.1% is optimally managed. Waste originates from households, commercial sectors, industries, and institutions. Universitas Singaperbangsa Karawang (UNSIKA) also generates waste daily; however, the university lacks a proper waste management system, resulting in waste accumulation on campus. This study aims to determine the waste generation and composition at UNSIKA as well as the reduction potential of food waste and recyclable waste. Recyclable waste was collected and delivered to local waste collectors around UNSIKA, while food waste was reduced using Black Soldier Fly (BSF) larvae through a 12-day bioconversion process. UNSIKA's waste generation reached 30.15 kg/day or 68.14 L/day. The largest composition was food waste at 29.81%, while rubber and textile waste were not found (0.00%). The reduction of recyclable waste through a 15-day collection period showed a 100.00% reduction rate. The reduction index of food waste by BSF larvae was 6.66%/day. With the use of 12 bioponds, the reduction rate increased to 79.92%/day. An economic feasibility analysis of UNSIKA"™s waste reduction activities indicated that the initiative is economically viable.

Abstract

The peel of Kepok banana (Musa paradisiaca L.) can be utilized as an environmentally friendly coagulant in the treatment of tofu industry wastewater. This study examined the effectiveness of the bio-coagulant derived from Kepok banana peel in comparison to the chemical coagulant Poly Aluminium Chloride (PAC) in reducing pollutant concentrations in the tofu industry "X". The coagulation-flocculation process was conducted at laboratory scale with varying coagulant doses of 0.4 g/L, 1.2 g/L, 2 g/L, and a control test. The mixing process involved rapid stirring at 200 rpm for 5 minutes, followed by slow stirring at 40 rpm for 10 minutes, and settling for an hour. The wastewater pH was optimized to 8. The results showed that a 0.4 g/L dose of Kepok banana peel reduced BOD levels by 29.8%, COD by 58%, and TSS by 41%. For comparison, a 0.4 g/L dose of PAC demonstrated higher effectiveness, reducing BOD by 26.8%, COD by 56%, and TSS by 28%.

Abstract

Seawater intrusion is a major threat to freshwater availability in coastal areas, particularly during dry seasons and spring tides. This study aims to analyze the distribution pattern of salinity and determine the maximum distance of seawater intrusion in the Jenu River, Kubu Raya Regency, West Kalimantan, to support the planning of raw water intake locations for the regional water utility (PDAM). Field data were collected over two days during the full moon phase (highest tidal range) at eight observation points along the Jenu Besar and Jenu Kecil Rivers. Salinity was measured at three vertical depths (0.2d, 0.6d, and 0.8d). The results show that the highest salinity values were observed near the river mouth at the bottom layer, while the lowest concentrations were found upstream at the surface layer. Polynomial regression analysis revealed a strong correlation between distance from the estuary and salinity concentration, with determination coefficients (R ²) of 0.9092 for Jenu Kecil and 0.9774 for Jenu Besar. The maximum intrusion distance was estimated to be ±17 km and ±17.5 km, respectively. The resulting polynomial equations can be used to predict salinity zones based on horizontal distance. The study recommends that PDAM raw water intake points be located beyond the intrusion zones (>18 km from the river mouth) to ensure compliance with water quality standards. Identified limitations include the short observation period and absence of real-time discharge and seasonal variation data. Further research is suggested to include hydrodynamic modeling and spatial salinity mapping to enhance the robustness of the findings.

Abstract

Improving water access in Indonesia requires reducing the Non-Revenue Water (NRW) level. One of Sumatra's largest water enterprises, Perumda Air Minum Kota Padang, has an NRW of 27.98% in 2024, compared to the national target of 25%. This research aimed to use the analysis of NRW performance indicators and water balance to develop a plan for minimizing water loss. The descriptive exploratory method is employed. According to the water balance analysis, Perumda Air Minum Kota Padang's NRW level in 2024 was 27.98%, or roughly 14,113,007 m ³. This consists of physical losses 8,229,365 m ³ (16.45%) and non-physical losses of 5,694,546 m ³ (11.29%). The NRW performance indicator was categorized in performance category C (poor NRW condition), but the physical water loss was categorized in performance category D (extraordinary resource wastage). To minimize water loss, it is advised to check for unauthorized connections, test and replace meters that are more than five years old, and replace the pipe network that has exceeded its technical life.
