Water efficiency and soil quality are key challenges faced by farmers at Pancasari Village, Buleleng, Bali, particularly in supporting sustainable agricultural practices. This community service project aims to enhance efficiency and sustainability through the implementation of smart farming technology using fertigation channels and the production of eco-enzyme liquid organic fertilizer. The implementation method consists of five stages: problem identification, socialization and education, planning and preparation, training and mentoring, as well as monitoring and evaluation. The results indicate a 30% increase in water efficiency, improved soil fertility with the use of organic fertilizers, and enhanced understanding and engagement of farmers in modern agricultural practices. The evaluation also recorded operational cost savings and increased agricultural productivity. Thus, this project provides effective and sustainable solutions to the challenges faced by farmers, while delivering significant environmental and social benefits.

Municipal solid waste (MSW) production continues to rise globally, especially in developing countries such as Indonesia, creating significant environmental challenges. This study investigates the impact of moisture content (MC) variation on ammonia (NH₃) and hydrogen sulfide (H₂S) emissions during the MSW drying process, and evaluates the effectiveness of a gas capture system using waste motor oil (WMO). Laboratory-scale experiments were conducted at Universitas Pendidikan Nasional in collaboration with Universitas Udayana, using MSW samples conditioned at five moisture levels: 50%, 40%, 30%, 20%, and 10%. Emissions were measured before and after treatment with the WMO-based interceptor system. The results showed that the highest gas emissions occurred at 50% MC, with corresponding reduction efficiencies of 73.9% (50% MC), 70.0% (40%), 72.1% (30%), 55.9% (20%), and 5.4% (10%). Higher MC was associated with increased anaerobic microbial activity and organic matter decomposition, leading to elevated NH₃ and H₂S generation. The WMO system demonstrated strong gas adsorption performance, particularly at moderate to high MC levels. These findings suggest that controlling MC and applying low-cost WMO-based gas interception can significantly reduce emissions in waste drying processes. This approach holds promise for improving air quality in urban waste management systems, especially in resource-limited settings.

The increasing ownership of motor vehicles has significantly contributed to heightened levels of traffic congestion. This study was conducted on Tukad Pakerisan Road in Denpasar City and aims to evaluate the current performance of the road segment by employing traffic modeling through Vissim software. The research adopts the Indonesian Highway Capacity Guidelines (PKJI) as the methodological framework. Data collection was carried out via a 12-hour on-site survey across two road segments of Tukad Pakerisan. The analysis revealed that the traffic flow volume reached 2025.45 Passenger Car Station/hour on Segment A and 1865.65 Passenger Car Station/hour on Segment B. The respective road capacities were 1877.669 Passenger Car Station/hour and 1671.583 Passenger Car Station/hour. The degree of saturation was found to be 1.08 on Segment A and 1.12 on Segment B, indicating Level of Service (LOS) F—characterized by severe traffic congestion. The simulation indicates significant future congestion, with projected saturation levels exceeding 1.5, underscoring the need for integrated mitigation strategies such as adaptive signal control and vehicle restriction policies. A five-year performance projection further suggests a continual increase in the degree of saturation, surpassing the acceptable limit of 0.85 as stipulated in PKJI 2023. These findings underscore the urgent need for capacity enhancement on Tukad Pakerisan Road. The study recommends the installation of additional traffic signage and the implementation of traffic engineering strategies to mitigate congestion along this critical corridor in South Denpasar.

The global energy crisis and Indonesia's dependence on fossil fuels (BBF) have driven the need to explore renewable energy sources. Biogas, as a sustainable solution, is produced through anaerobic degradation of materials with methane (CH₄) 50–75% and carbon dioxide (CO₂) 30–45% as its dominant components. Agro industrial waste such as durian peel shows great potential for biogas production, as Indonesia produces more than 19 thousand tons of durian annually according to the 2024 Statistics Indonesia report. Utilizing durian peel is ideal since its composition (65–80%) is significantly higher than that of the pulp (20–35%) and seeds (5–15%). This study employed a substrate ratio of 5 grams of total solids (TS) + 100 mL of inoculum + 200 mL of distilled water, with intermittent stirring (three times per day, 1 minute per session). The tested temperature variations under thermophilic conditions 40°C, 45°C, and 50°C, including one control without heating. The analysis focused on daily pressure accumulation and gas composition profiles (CH₄ and CO₂). The results show that 40°C (thermophilic condition) achieved maximum efficiency due to optimal methanogenic microbial activity, producing higher methane (CH₄) yield compared to other temperatures. This study contributes to the development of renewable energy from agricultural waste in tropical regions and supports Indonesia’s national energy transition program.

This program focuses on enhancing the understanding, skills, and participation of the Besakih Village community, Rendang District, Karangasem Regency, in implementing organic farming systems, particularly in the cultivation of aloe vera. The focus emerged from the low level of awareness and capability among farmers in applying Standard Operating Procedures (SOPs) for organic farming, which play a crucial role in maintaining environmental sustainability and improving agricultural productivity. The program was designed as a strategic effort to promote environmentally friendly and sustainable plantation management by reducing dependence on chemical fertilizers and pesticides, in collaboration with a private company in the food manufacturing sector, PT. Alove Bali Ind. The activities were conducted in three main stages: education, implementation, and evaluation. The education stage emphasized the dissemination of organic farming benefits and the introduction of aloe vera cultivation SOPs facilitated by PT. Alove Bali Ind. The implementation stage involved direct field assistance to ensure the effective application of land transfer, composting, and plant rejuvenation practices. The evaluation stage was carried out collaboratively among academics, industry partners, and the community to identify challenges and formulate sustainable solutions. Farmer empowerment in adopting organic farming practices increased by approximately 71%, leading to greater income stability and growth within the community. This program serves as an effective model of cross-sector collaboration in developing an environmentally based community empowerment initiative that can be replicated in other regions with similar agricultural potential.
