Abstract

Collaboration between academics, educators, students, village civil servants, and the community is needed to implement Sustainable Development Goal (SDG) 6. It is related to clean water and sanitation in the context of training vocational teachers and students to provide it to the community. First, measurements were made of the water quality around the research area. Sixty-three water samples were drawn from each resident's home's water supply. A multi-parameter water quality checker was used to evaluate the samples, and then spatial data processing was used. A temperature of 24.1 C, turbidity of 0.4 NTU, conductivity of 0.4 mS/cm, pH 7.1, salinity of 0.2 ppt, DO of 5.9 mg/l, and TDS value of 267 mg/l were measured. These average results indicate that the water quality satisfies both Indonesian National Standard 3553:2015 and the water quality criteria set by the Minister of Health of the Republic of Indonesia Regulation No. 2 Year 2023. However, the results of tracking every sampling location show that several samples fall short of water quality requirements because of the high mineral content, weather, and other factors. Every school and community organization needs to run scenarios to raise awareness about water quality standards involving the government, non-governmental organizations, and the private sector to implement SDGs 6, such as stakeholder engagement, community enhancement, and policy and regulation.

Abstract

Traditional sugar factories face challenges in improving production efficiency to remain competitive and meet growing market demand. This research adopts an innovative STEM (Science, Technology, Engineering, and Mathematics) approach to analyze material and energy flows in the sugar production process. This approach not only identifies inefficiencies but also offers data-driven solutions and modern technology for operational optimization. The research involved material and energy flow mapping using the mass and energy balance method, along with causal analysis to identify the root causes of inefficiencies at each stage of production, from preparation, milling, refining, to crystallization. The results showed a production yield of 6,63%, far below the company's target of 10%, with the main inefficiencies caused by low raw material quality, non-standard process temperature settings, and inadequate operator skills. STEM-based recommendations include integrating sensor technology for real-time monitoring, regular machine maintenance using predictive algorithms, creating digital guidelines for operators, and optimizing raw materials through agronomic data. Implementing this approach is expected to improve yield and production efficiency and support operational sustainability by reducing waste and emissions.

Abstract

Drop testing is a key method in evaluating the mechanical durability of packaging and products during distribution. This research develops a low-cost drop tester prototype that is precise and applicable for academic environments, referring to ASTM D5276 and ISTA standards. The integrative design using CAD/CAE and FEA simulation ensures the mechanical strength and reliability of the structure, while the electronic system based on microcontroller and ultrasonic sensor supports digital drop height measurement and deformation monitoring through high-speed camera. Experimental validation shows an average fall height deviation of less than 1 mm with stable fall orientation and quick release mechanism. Weaknesses such as the absence of arm height limit, limitations of the load cell sensor in recording load peaks, and the need for lubrication and maintenance of the slider are the focus of further development. Recommendations include full automation of data logging and application of AI for video analysis of the test process. This prototype has the potential to improve the quality of practicum learning and open up space for research development and packaging industry applications.

Abstract

This research combines Life Cycle Assessment (LCA) and Carbon Accounting to quantify sustainability performance improvements in ammonia production. Emphasis is placed on gate-to-gate in the start-up phase of the purifier unit where energy use is high. Typically, start up in ammonia plants is a 20-25 hour long process that consumes large volumes of natural gas and steam resulting in substantial carbon emissions and inefficiency. This statement presents the technology of LIN (Liquid Nitrogen) Injection, which is used to accelerate the cooling process of purifier units at a temperature between −100 to−186 °C, reduces star-up duration by an estimation about 10.56 hours. ISO 14064-1 and SNI 7724:2011 standards were used, a gaseous mass, energy, and emission balance was carried out. Results also indicate that LIN Injection reduces natural gas consumption of 10.92 tons, steam with a factor of 899.56 tons and total energy Mech/ηµ using start-up cycle 592.89 GJ. This is equivalent to 33.3-34.2 tons of CO₂e emission reduction. This process-oriented decarbonization supports the MRV system, which enables carbon credit registration according to Indonesian’s IDX Carbon market framework.
