Abstract

Freshwater fish cultivation in Pulotondo Village, Ngunut District, Tulungagung Regency, East Java, has significant potential to increase income and improve the well-being of the community while fostering sustainable economic growth. Ponds managed collectively by the Village-Owned Enterprises (BUMDES) serve as a facility for freshwater fish cultivation, with an annual production of 220 tons. One of the obstacles to the development of this business is the enhancement of the value and shelf life of processed fish products. Therefore, the Community Service activity in Pulotondo Village focuses on training in the processing of freshwater fish products. Through this initiative, BUMDES and the community can enhance understanding and skills, enabling processed products to be stored longer and have a more competitive market value. To assess the training's impact, participants provided feedback through a questionnaire. The results indicate that the training activities were well-understood by the participants, showing an indication of increased entrepreneurial spirit through local potential.

Abstract

The Community Service (CS) project was implemented in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, East Java. The target beneficiary was UD. Arta Lumintu, a local SME engaged in beef cattle farming. The farm, established in 2017, was temporarily closed due to the Covid pandemic and resumed operation after a year. Key challenges included high temperatures (24-31°C) and humidity (74-77%), which negatively impacted cattle productivity and excessive electricity consumption for cattle shed operations. The project aimed to address these issues by installing a water spray system with a high-pressure pump and an off-grid solar power system. The system effectively reduces temperature and humidity in the sheds while minimizing electricity costs. The installation consists of a 540 Wp solar panel, a 1500 VA Smart inverter, a 100 Ah VRLA battery, and six pressurized water sprinkler points positioned in various areas of the cattle sheds, powered by a 350 W booster pump. This initiative improves farm efficiency, supports energy independence, and introduces smart farming technology to benefit local farmers.

Abstract

Thin films, characterized by small-dimensional materials on a substrate formed through sequential deposition of ionic/molecular/atomic materials, have gained significance in various industries. An emerging method, Arc Plasma Deposition (APD), is gaining attention for its effectiveness in minimizing environmental pollution. This research explores the potential of APD, an environmentally friendly technique, in coating materials, particularly copper, at a laboratory scale. The objective is to introduce a cost-effective solution for material deposition, addressing the industrial need for efficient and eco-friendly coating processes. A laboratory-scale prototype for coating materials, specifically utilizing copper metal, is introduced and tested. The APD process is conducted in an atmospheric free-oxygen chamber, where plasma is generated. The deposited copper is analyzed concerning the deposition time, providing insights into the efficiency of the APD technique. The laboratory-scale prototype demonstrates the feasibility of using APD for coating materials. The results indicate the potential of APD in efficiently producing thin films, making it a promising alternative for industrial applications.

Abstract

In Kemlagi District, Mojokerto Regency, a small and medium-sized batik enterprise, CV Ulur Wiji Muda Berdaya, has gained popularity among millennials due to its use of natural dyes that are environmentally friendly. The products have not only attracted domestic consumers but have also reached international markets. Despite this achievement, the enterprise continues to face a major challenge in managing batik dye wastewater, which has not received optimal treatment. To solve this issue, a community service program was implemented to provide technical assistance in wastewater treatment through training on filtration adsorption methods for the employees of CV Ulur Wiji. The filtration unit employed adsorption media consisting of foam filters, zeolite, activated carbon, coral stone, and Malang sand. The questionnaire results confirm that the partner has improved the application of wastewater treatment technology as a result of the program. The results of batik waste processing indicated an improvement in the waste quality, changing from a turbid color to a clearer appearance, with an initial pH of 6.3; after undergoing filtration-adsorption, the pH shifted to near neutral at 6.9. Furthermore, an additional outcome of this program is the successful development of an appropriate technology system for treating wastewater from batik dye using filtration–adsorption techniques.

Abstract

Palm oil offers advantages as a lubricant due to its eco-friendliness, renewability, high viscosity index, good boundary lubrication properties, and compatibility with additives. However, palm oil is not very resistant to high-temperature changes, which limit its application in vehicle lubricants. This research aims to overcome the weaknesses of palm oil as a vehicle lubricant by adding Nonylphenol and Polyethylene Glycol surfactants at varying concentrations and evaluate thermal stability, engine operating temperature, and corrosion resistance.  The quantitative experiments were conducted with palm oil blend of nonylphenol surfactant and polyethylene glycol. Formulations containing 2.5%, 5%, and 7.5% surfactant concentrations were evaluated through oven-based thermal stability testing and copper strip corrosion testing according to ASTM D4048 to determine the sulfur content in lubricating oils. From the test results, palm oil-based lubricant blends containing Nonylphenol (2.5% and 5%) and Polyethylene Glycol (PEG) (2.5% and 5%) showed a corrosion classification value of 1a, the best rating in the ASTM Copper Strip Corrosion Standard. The best engine temperature test was palm-oil-based with 5% Nonylphenol.

Abstract

Batik wastewater generated by micro-scale industries typically contains high organic loads, intense coloration, and fluctuating pH, exceeding national discharge limits. This study aims to design, install, and evaluate a simple pilot-scale wastewater treatment plant (WWTP) using a coagulation–filtration–adsorption process for UMKM Batik Ulur Wiji in Indonesia. Wastewater quality was analyzed before and after treatment for pH, BOD, COD, TSS, TDS, turbidity, and color referring to Indonesian Ministry of Environment Regulation No. 5/2014. The results show a substantial improvement in water quality, with COD reduced from 857 to 112 mg/L and BOD from 358 to 68 mg/L. Turbidity decreased from 218 to 14 NTU, and color removal was visually significant. The treated effluent met key parameters for non-potable reuse. A partner satisfaction survey revealed increased environmental awareness, full operational understanding of WWTP, and long-term commitment to system use. This study demonstrates that simple low-cost treatment units are effective for batik wastewater management in micro-industries and provide a replicable model for community-based environmental interventions.
