Indonesia merupakan negara agraris yang mempunyai wilayah pertanian yang luas. Daerah kecamatan Cepu, Blora adalah salah satu wilayah dengan lahan kelola perhutani yang cukup luas dan belum dimanfaatkan secara maksimal. Dalam pengelolaan lahan pertanian ini air merupakan kebutuhan yang utama dalam mengelola lahan pertanian. Sedangkan kontur tanah di wilayah cepu tidak menjamin tersedianya air di setiap lahan . sehingga masyarakat dihadaoka pada masalah ketersediaan air yang tidak konsisten. Solusi kebutuhan ini dibutuhkan sistem irigasi yang baik saat terjadi musim hujan maupun kemarau. Secara konvensional pengunaan diesel pompa air dengan bahan bakar minyak untuk sistem irigasi pertanian diperlukan biaya mahal dan tidak efektif. Pemanfaatan tenaga surya untuk pompa air merupakan salah satu alternatif solusi yang handal, hemat, efektif dan efisien untuk menjaga sistem irigasi tetap berjalan dengan baik saat musim kemarau. Pada pengabdian ini telah berhasil diimplementasikan penggunaan pompa dengan beban 125 watt yang mampu beroprasi 8 jam perhari dengan listrik tenaga surya 500 WP. Panel surya ini mampu menghasilkan daya listrik 2000 watt dengan asumsi waktu efektif 4 jam terpapar matahari penuh. Dalam keadaan tidak ada sinar matahari, dengan daya yang dimiliki pompa mampu bisa dioperasikan 14,4 jam atau sekitar 2 hari.

This paper addresses a common gap in pump transmission design that relies on “allowable stress + safety factor.” This paper redesign a complete shaft key coupling bearing train of a 5.5 kW/1450 rpm centrifugal pump using a reliability based framework. A field case uses nameplate data and dimensional measurements. Methods include ASME/DE von Mises formulation for combined bending torsion, stress concentration factors for keyseat/fillet, consistent torque path sizing of key and flange coupling, and bearing L10 life per ISO 281. All calculations use SI units with ±5–10% uncertainty propagation. Results show an S40C shaft ds≈33.3 mm, a 10×8×15 mm key, a flange coupling passing shear/crushing checks, and an angular contact bearing meeting a 20–40 kh life target, sensitivity highlights Kt and equivalent bearing load as dominant drivers. This paper recommend as a design for reliability guide for maintenance friendly pump trains in SME/utility settings, complemented by targeted vibration tests.

Gas turbines are one type of internal combustion drive, the initial mover utilizes gas combustion as a fluid to rotate the turbine with internal combustion. Gas turbines at private companies producing electricity use the initial movers, namely gas turbines and steam turbines. Therefore, it is also called the "Steam Gas Power Plant/PLTGU.”Private company especially in Block 2, uses two gas turbine units with Mitsubishi GT 2.1 specifications which are used as the initial drive of the generator. Types of overhauls in gas turbines are divided into three, including turbine inspection, combustor inspection, and major inspection. In maintaining the reliability of the GT 2.1 Gas Turbine, an overhaul combustion inspection was carried out in the combustion chamber because there was an increase in heat rate of 17,9% which caused a decrease in thermal efficiency and net turbine power of the GT 2.1 Gas Turbine by 17% and 2,1%. So that steps are taken to optimize the GT 2.1 Gas Turbine with the combustion inspection method by repairing and cleaning the combustion bucket nozzle. Increased thermal efficiency by 27,8% or 27,13% to 36,01% from data before overhaul. This was also followed by an increase in compressor power and turbine power so that the net turbine power increased by 38% or 141339,35 hp to 195246,54 hp.

Fire incidents continue to increase in various regions in Indonesia due to low public awareness of prevention and early response measures. This community service activity aims to improve students' knowledge, skills, and preparedness in using fire blankets and portable fire extinguishers through experience-based training. The implementation methods include interactive lectures, live demonstrations, and controlled firefighting simulations. Pre- and post-training evaluations were used to measure changes in knowledge, skills, and safety attitudes. A total of 180 participants (aged 15–18 years) attended the training and completed the entire evaluation series. The results showed an average increase in knowledge scores from 52.3 to 86.8 points (+66%). Practical competence increased from 14% to 81% of participants who were assessed as being able to use the tools correctly. Attitudes and confidence in emergency response also showed significant improvement, from a score of 2.4 to 4.1 on the Likert scale. Qualitative feedback confirmed that participants felt better prepared to deal with small fires and had a better understanding of the importance of a safety culture in the school environment. These findings indicate that practice-based training is effective in strengthening fire preparedness among secondary school-aged groups. This workshop model offers an educational approach that can be replicated by other educational institutions as a risk mitigation strategy and to strengthen community-based safety culture.

Seasonal dry periods in Blora Regency routinely lead to drought conditions, which make it difficult for communities to secure clean water for daily use and for agricultural irrigation. This community service initiative aimed to deliver a rapid energy-based solution by implementing the Quick Response Energy (QREEN) system to support water distribution and environmental lighting in Ledok, Temengeng, and Joho Villages. The program followed a community based participatory approach with five stages, namely problem identification grounded in field data, technology solution design, site selection, implementation coordination, and program evaluation. Using a mixed methods design, data were collected through direct observation, semi structured interviews, and quantitative surveys administered to selected users. The results indicated high user satisfaction, including improved ease of access to clean water (79 to 85%) and time savings (75 to 83%), as well as increased farming yields (72 to 80%) among users who manage agricultural land. Overall, the findings suggest that QREEN implementation can strengthen local water security, although the magnitude of impact varies across contexts. Sustained, cross sector collaboration is recommended to support long term operation and enable program expansion.
