Abstract

The Tanjung Village of  Jepara Regency is located on the slopes of Muria Mountain. Most of the livelihood of the villagers is farming. one of the plants that are suitable to be planted in this area besides rice is coffee. Most of the residents grow coffee only for personal consumption and not for sale. This is because the selling price is cheaper. The partner we invite to cooperate in this service activity is Tanjung Java Coffee. It was initiated by Mr. Nor Rokhim in 2018 with 5 employees. Previously in Tanjung Village, there was no coffee business so Tanjung Java coffee was a pioneer who started a coffee business there. The Partners Had problems are 1) at the roasting steps still using the 2nd party so that the roasting cost is expensive, 2) Marketing is still manual with a consignment system and offers to coffee shops in Jepara. Solutions to overcome these problems are through socialization methods, IoT and internet marketing training, application of roasting equipment and training on layout, mentoring, evaluation and monitoring. The results of this activity benefit partners by increasing the production capacity 33%, assets 60%, benefits 2%, and skills partners.

Abstract

Tata letak fasilitas menjadi hal yang penting berkaitan dengan produktivitas kerja. Salah satunya adalah di area produksi di ABC Bakery. Masalah yang terjadi adalah masih terjadi perpindahan material dengan jarak yang cukup jauh yang menyebabkan sering terjadi arus bolak balik di dalam lantai produksi. Selama ini, penataan di area produksi hanya berdasarkan ruang kosong yang ada pada area produksi. Sehingga perlu dilakukan perbaikan dalam tata letak fasilitas. Metode yang digunakan adalah Activity Relationship Chart. Hasil yang didapatkan dari penelitian ini adalah

Abstract

All companies hope for an effective and efficient production system, but an imperfect production system means that PT XYZ must improve its production activities. The company strives to produce good products followed by a high level of productivity. In this research, we investigate a case at PT XYZ which produces hot stamping foil in the rewind section. This research found that there was waste that occurred in set-up replacement activities in production. Because it requires a long processing time, we perfected the system by implementing the Single Minute Exchange of Dies (SMED) method, then the process optimized internal activities in the set-up process. The application of the SMED concept is carried out by changing internal activities into external activities with the addition of helpers. This research aims to provide a more effective and efficient set-up replacement process so that machine downtime can be reduced. The results of this research show a 52% reduction in set-up time obtained by adding a helper with a time before implementation of 58 minutes to 30 minutes. This research concludes that SMED is effective in reducing machine set-up time and increasing the efficiency of the production process with benefits after implementing the SMED method by adding a helper of Rp. 10,649,336. In this way, implementing the SMED method helps companies increase production set-up replacement times in the rewind section.

Abstract

Bermi Village is one of the villages in Mijen District, Demak Regency. The existence of Bumdes in a village is currently important for the development and independence of the village. With quite a lot of village potential, including Sumur Gandeng, onion farmers, rice farmers, water hyacinth craftsmen groups, catering, and waste that is not managed properly. However, until today the lack of good management has become an obstacle for Bumdes in Bermi Village. In terms of legal aspects, improvements need to be made, and there are no productive businesses operating from the potential of Bermi Village. Based on this background, this service aims to help Bermi Village in increasing knowledge of Bumdes management, by conducting socialization and Discussion (Focus Group Discussion) of village potential which is used as a productive business plan to be implemented. The results of this service, as many as 92% of participants stated that they understood and understood the socialization given (with details of 35% very understanding, and 58% understanding), and it was decided that several business plans that would be implemented were the management of Bumdes cooperatives for productive businesses, management of Sumur Gandeng as a tourism business, and management of village-level waste as a form of non-productive Bumdes business. So that with this service, Bumdes becomes well organized in organizational administration.

Abstract

This study also highlights the importance of education and training for farmers to improve their technical skills in farming and managing their farms. Training in the use of modern agricultural technologies, such as automated fertilizing tools and efficient irrigation systems, can help farmers reduce production costs and increase yields. Furthermore, training in digital marketing can help farmers market their products more effectively through online platforms, reducing reliance on intermediaries and increasing profit margins. Furthermore, it is crucial for the government to provide support in the form of extension services and easy access to business capital. More accessible capital will enable farmers to invest in more efficient equipment and more environmentally friendly organic fertilizers. Targeted microcredit distribution to farmer groups can also accelerate the adoption of new, more productive agricultural technologies. The adoption of sustainable and environmentally friendly agricultural practices should be a long-term focus to ensure the registration of shallot farming businesses. Farmers need to be incentivized to use organic fertilizers and natural pesticides that are safer for the soil and air. Furthermore, the implementation of integrated and environmentally friendly farming systems such as agroforestry can also be an alternative to increase agricultural yields without damaging the environment. With improvements in education, training, access to capital, and the adoption of more efficient technology, shallot farming in Pasir Village can develop better and become more sustainable in the future. Furthermore, collaboration between farmer groups and local research institutions and universities can also be key to introducing new agricultural innovations.

Abstract

Distribution is an important aspect that affects the operational efficiency of a company, especially in terms of goods delivery. This study aims to develop an optimization model for LPG gas distribution routes using Excel Solver based on geographic coordinate conversion. In this study, the method used includes converting geographic coordinates from decimal to Degree-Minute-Second (DMS) format, followed by conversion to kilometers to form a more accurate distance matrix. The optimization model was built using the Capacitated Vehicle Routing Problem (CVRP) approach, which takes into account vehicle capacity constraints (a maximum of 560 cylinders per truck) and the limited number of available fleets, which is only one truck. The results show that coordinate conversion produces high accuracy in calculating distances between distribution locations. By using Excel Solver, the optimization solution successfully minimizes the total distance traveled compared to the conventional route, where distribution is carried out more evenly to 57 scattered LPG base locations. The addition of Solver Parameters Evolutionary and All Different constraints proved effective in avoiding duplication of visits and producing optimal distribution routes. This solution not only improves distribution time and cost efficiency, but also improves service to customers by reducing delivery delays. The success of this optimization model is expected to be implemented by other distribution companies to improve their operational performance. This study also highlights the importance of selecting the right software to aid the distribution optimization process. Excel Solver, despite its simplicity, proved highly effective in solving complex distribution routing problems, especially when combined with coordinate conversion techniques that yield more accurate distances. Furthermore, the application of the CVRP method enabled more efficient decision-making in determining distribution routes, taking into account vehicle capacity and fleet limitations.
