Cimenyan District has a problem in the form of accumulation of waste which pollutes the environment and endangers health. Another problem is the very high price of animal feed because it has to be imported from abroad. An alternative solution to these two problems is to use the Maggot Black Soldier Fly (BSF). BSF maggot is proven to be able to decompose organic waste, it is also animal feed that has high nutrition. Research objectives: (1) to describe the implementation of community development activities regarding how to cultivate BSF maggot in Cimenyan District, (2) to analyze the results of a simulation on the future prospects for BSF maggot cultivation to motivate training participants and readers regarding its potential. This coaching involved 17 participants which was carried out online and offline. Participants were given modules and then guided to carry out cultivation practices. The author also simulated the prospects for BSF maggot cultivation using the dynamic system method. The output of this research is how to cultivate BSF maggot and simulation results using a dynamic system which shows the potential for very good BSF maggot cultivation in the next ten years that the government needs to consider both in reducing organic waste, as a substitute for animal feed, and as a business product to create a circular economy and also support the Sustainable Development Goals (SDGs) targetsCimenyan District has a problem in the form of accumulation of waste which pollutes the environment and endangers health.

The route arrangement between Husein Sastranegara International Airport Bandung and BIJB Kertajati Airport does not directly impact the increase of passengers at BIJB Kertajati Airport. One of the reasons is because of the alleged selection of airports by air transport passengers, especially in the Bandung Raya area. West Java air transport passengers, especially for the Bandung Raya area, prefer Bandung's Husein Sastranegara International Airport by utilizing the available routes, which is considered to be one of the causes of the decreasing number of passenger movements at BIJB Kertajati Airport after the route arrangement. Land transportation conditions that take 3-4 hours from Bandung to BIJB Kertajati Airport cause the passenger to consider the time by leaving earlier to fly from BIJB Kertajati Airport. On the other hand, with almost the same travel time and distance, air transport passengers can access Soekarno -Hatta International Airport, Tangerang, which offers various advantages. The phenomenon of airport leakage is suspected to be the cause of the increase in passenger movements at BIJB Kertajati Airport. This study uses an explanatory survey method. The analytical approach used in this study is Partial Least Square (PLS) using SmartPLS version 3.3.2 as a means of data processing. The results of data processing reveal that Passenger
Household waste in Bandung City is one of the problems due to the increase in waste generated by the community from year to year and the limited land or Final Disposal Site (TPA) in Bandung City. The land capacity at the Final Disposal Site of Sarimukti decreases every year and the waste generation reaches 9 meters. This happens because there is no effective and efficient waste management technology. To overcome this waste generation, this research was carried out which aims to find out how the current household waste is processed, identifying lean operations of zero waste management processing, perform a zero waste management technology simulation using a dynamic system, comparing the total costs required with the total benefits received when using zero waste management technology, and designing a lean canvas business model for the processing of zero waste management. This study uses a cost benefit analysis method with a System Dynamics approach in conducting model simulations and designing a lean canvas business model for zero waste management. The results of the study consist of three scenarios, namely pessimistic, most likely and optimisticic scenarios, each scenario shows that Bandung City can achieve zero waste conditions in the fifth year for the most likely scenario and the fourth year for the optimisticic scenario except for the pessimistic scenario. Benefit Cost Ratio value for pessimistic scenario is 0.660, Most Likely scenario is 0.767, optimisticic scenario is 1.172. This method allows the occurrence of lean operations in waste management which are shown by flowcharts and process graphs by eliminating activities that do not have added value. Furthermore, to support the operations of this research, a recommendation is made in the form of lean operations using 5S on household waste sorting behavior and the preparation of a lean canvas business model so that the implementation of Zero Waste Management is optimal
Kedelai adalah salah satu tanaman polong-polongan yang menjadi bahan dasar banyak makanan dari Asia Timur. Kedelai merupakan bahan pangan yang penting bagi masyarakat Indonesia, dan kedelai merupakan tanaman pangan utama selain padi, ubi, dan jagung. Kedelai merupakan bahan baku makanan yang bergizi seperti tahu dan tempe Kontribusi ekonomi yang besar dari tempe juga didukung oleh faktor budaya. Tempe merupakan bagian dari budaya pangan Indonesia. Kedelai sebagai bahan baku yang banyak digunakan, namun produksi kedelai dalam negeri tidak mampu mecukupi kebutuhan konsumsi kedelai, sehingga yang dilakukan pemerintah adalah dengan impor kedelai. Permasalahan dari penelitian ini adalah fakor-faktor apa saja yang berpengaruh terhadap permintaan kedelai di Jawa Timur. Penelitian ini menggunakan data provinsi Jawa Timur, dengan pertimbangan bahwa Jawa Timur sebagai provinsi yang memberikan sumbangan produksi dalam negeri terbesar. Analisis ini menggunakan regresi linier berganda dimana variabel yang digunakan dalam penelitian ini adalah harga kedelai lokal, harga kedelai impor, jumlah penduduk dan perndapatan per kapita. Jenis data yang digunakan adalah data sekunder yaitu data yang diambil dari data yang dipublikasikan seperti dari BPS, Pusat Data dan Sistem Informasi Pertanian.
BFM is a pharmaceutical company that produces bulk Tetanus Toxoid (TT). Bulk TT demand will continue to increase until 2025, while the current utilization rate has reached 97% of its design capacity. Bulk TT's current production capacity is insufficient, while the building area cannot be enlarged. This research was conducted to improve non-necessary value added by identifying and reducing waste to run well even though the production capacity is limited. Mix descriptive qualitative and quantitative methods are applied in this research. Production simulation is undertaken to reduce waste through the Gemba Kaizen approach and Kanban, while production capacity simulation is carried out using Dynamic Systems. The results of the simulations are described in the Balanced Scorecard. The research revealed there are 148 wastes consisting of 4 causes of waste in the high priority category, 20 medium priority and 124 low priority. The simulation generates a significant decrease value of the waste priority number (WPN) from 347.3 to 47.2. There was also an increase in the overall value stream. Value-added ratio (VAR) increased 12.57%, production lead time reduced 21.01%, and total cycle time decreased 11.65%. These findings indicated that the improvement was effective in eliminating waste. From the overall improvement, there was an increase in productivity of 25.0%.
