Public street lighting, also known as street lighting, refers to the outdoor lighting systems used to illuminate public roads. An effective street lighting system plays a crucial role in enhancing safety and security for pedestrians, cyclists, and motorists by providing improved visibility of the road and surrounding terrain during nighttime hours.  The primary focus in street lighting planning is on economic factors. An analysis of light sources has highlighted the economic advantages of utilizing light emitting diodes for public street lighting. This choice proves to be more efficient when implemented in a sustainable manner. The installation of public street lighting can be the optimal solution to address the issue of inadequate lighting in the village of Pedurenan Gunung Sindur Bogor, ensuring enhanced comfort and security during nighttime activities. The lighting installation process commences with a thorough examination of the site, followed by diligently arranging and design of the electrical installations for the lighting system. Finally, the planned design was carried out and implemented. The implementation of public street lighting is a collaborative effort between college students and youth residents in the village. The outcome of this community service initiative is the implementation of public street lighting installations that offer optimal illumination, ensuring the convenience and safety for all people accessing the roads.

Permasalahan yang terjadi di Desa Gunungsari yaitu kurangnya sarana infrastruktur seperti plang jalan dan cermin cembung. Hal ini sangat berguna apalagi terdapat banyak jalan-jalan kecil dan gang yang berada di desa sehingga mempersulit pengguna jalan yang melalui jalan desa. Dengan adanya permasalahan yang ditemui sehingga perlu upaya peningkatan sarana infrastruktur yang memadai. Kegiatan pengabdian masyarakat ini dimulai dengan mengadakan survei lokasi titik dimana akan diberikannya nama-nama plang jalan dan cermin cembung. Adapun jumlah plang nama jalan yang dibuat sebanyak 6 buah dan 2 buah cermin cembung. Kegiatan ini sangat disambut positif oleh warga desa mulai dari proses persiapan hingga dengan pelaksanaan pemasangan. Dengan adanya pemasangan nama jalan dan cermin cembung di desa menjadi startegi penting dalam peningkatan insfrastruktur jalan, mulai dari memperjelas navigasi dan meningkatkan keselamatan pengguna jalan pada akhirnya juga membuka akses yang lebih luas terhadap poteensi pembangunan ekonomi dan sosial di desa.

Purworejo Village, Ngantang District, Malang Regency is one of the onion producers in East Java. Purworejo Village has geographical and climatic conditions that support the growth of onions well. Fertile soil and sufficient rainfall enable farmers to obtain optimal harvest results. Agricultural knowledge and traditions that have been passed down from generation to generation have become valuable capital for local farmers in managing shallot crops well. In Purworejo Village there is agricultural land that uses a greenhouse system, however the green house has been unused and neglected because it is poorly maintained. The PPK HMD Management team is working together with the Karya Bakti 1 Farmers Group in Purworejo Village to revitalize and reuse greenhouse agricultural land for planting shallots. Methods used in revitalization include evaluating land conditions, soil analysis and fertilization, water management, and routine maintenance. The results of the revitalization of the greenhouse will be used as an outdoor education center which is useful for providing experience in raising shallots through to the harvesting process as an application of shallot farming theory.

The involvement of accounting and management lecturers in the training and business support of micro, small, and medium enterprises (UMKM) and Kripik Tempe Rohani plays a crucial role in the advancement of UMKM and the local economy. This scholarly article explores the significance of initiatives aimed at enhancing financial literacy. The lecturer specialising in accounting and management delivers comprehensive training sessions on financial management, taxation, and accounting practices to micro, small, and medium enterprises (UMKM). Additionally, the lecturer offers valuable advice on the practical implementation of these principles within the context of everyday business operations. Furthermore, the instructor has the capability to acquaint UMKM (micro, small, and medium enterprises) with accounting software and provide guidance on comprehending tax responsibilities. The positive effects encompass enhanced economic well-being of micro, small, and medium enterprises (UMKMs), less business risk, adherence to tax responsibilities, sustained growth, heightened competitiveness, and facilitation of local economic progress. The provision of training and support services additionally enhances individuals' financial literacy, thereby playing a significant part in the overall improvement of society's economy.

Solar energy is a potential solution to meet the electricity needs of TNI AD posts and bases in border areas. However, conventional solar energy systems have limited efficiency because they can only absorb sunlight from one direction. The efficiency of solar energy systems can be improved by using a dual-axis tracking system equipped with a LDR sensor. The LDR sensor is used to detect the direction of sunlight. The change in the LDR sensor resistance due to the change in the intensity of light that hits it is then processed by a microcontroller to move the solar panel in the appropriate direction. Based on the results of testing, the dual-axis tracking system with an LDR sensor significantly increases the power generated compared to conventional solar energy systems. At the peak of performance during dynamic testing at 12:00 pm, the total power reached 2,196 W, while the static test reached a total power of 1,311 W. Therefore, the dual-axis tracking system with an LDR sensor can be a more optimal choice to improve the performance and efficiency of solar energy systems in generating electricity at TNI AD posts and bases in border areas.

Solar energy installations mathematically and visualization using the Solar Global Atlas Software simulation. The data obtained is that the highest energy occurred in the second test with the result of 365.7 Wh with the maximum power generated by solar panels of 93.28 W, battery charging energy of 321.5 Wh with a maximum battery charging power of 76.78 W. Sunhour that occurs is obtained 3.66 h with solar panel efficiency that occurs at 12.8%. The research methods used include quantitative research methods by taking data using measuring instruments using literature studies, simulations and experiments to then be processed using related formulas in the implementation of the research.
