Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Sungai Cikapundung tidak bisa dipisahkan dari masyarakat Kota Bandung, selain karena sangat berarti bagi kehidupan warga Bandung dan sekitarnya juga sungai tersebut memiliki fungsi hidrologis bagi Cekungan Bandung. Namun sayangnya Sungai Cikapundung juga telah menjadi tempat pembuangan berbagai limbah warga Kota Bandung sehingga kualitas air sungai menurun. Salah satu penyebab tercemarnya Sungai Cikapundung adalah pembuangan limbah padat atau sampah rumah tangga. Hal ini disebabkan karena manajemen pengelolaan sampah di DAS Cikapundung kurang baik, baik dari segi infrastruktur maupun manajemen. Pengelolaan sampah terpadu berbasis masyarakat melalui penguatan ecopreneur ini merupakan alternatif yang ditawarkan untuk model pengelolaan sampah di DAS Cikapundung. Konsep tersebut memadukan tiga komponen penting dalam pembangunan berkelanjutan yakni lingkungan, ekonomi dan sosial.

Abstract. Usaha Rintisan Kue Tradisional Ibu X is a business engaged in the culinary field by producing and selling twelve kinds of traditional snacks. Usaha Rintisan Kue Tradisional Ibu X is included in the criteria for a micro business because the assets owned are < Rp. 50 million and the turnover is still < Rp. 300 million/year and the number of workers owned is < 5 people. Traditional cake startups often experience obstacles when doing their business, one of which is the fluctuating price of raw materials that affects the amount of profit earned. As a business that is just starting a business, a startup has a goal to make a profit and remain sustainable in the future. In order to determine whether the pilot business will continue to be sustainable in the future, a simulation model with a dynamic system approach is made. The steps taken in this study are based on a dynamic system simulation approach, including problem identification and definition, system conceptualization, model formulation, model simulation, policy analysis and policy implementation. The results of this research show that until the 100th period (April, 2028), traditional cake startups remain sustainable while still generating profits every month. Scenario test was carried out by changing the price of the product/pcs to Rp. 1,500/pcs when there is an increase in the price of raw materials which can be a consideration for start-up business owners to increase prices when raw materials increase, so that the startup can make a profit and will be sustainable in the future. Abstrak. Usaha Rintisan Kue Tradisional Ibu X merupakan usaha yang bergerak dibidang kuliner dengan memproduksi dan menjual dua belas macam kudapan tradisional. Usaha Rintisan Kue Tradisional Ibu X termasuk pada kriteria usaha mikro karena aset yang dimiliki < Rp. 50 juta dan omzet yang didapat masih < Rp. 300 juta/tahun dan jumlah pekerja yang dimiliki <5 orang. Usaha rintisan kue tradisional sering mengalami kendala saat melakukan usahanya, salah satunya adalah harga bahan baku yang berfluktuasi sehingga mempengaruhi jumlah profit yang didapat. Sebagai usaha yang baru merintis usaha, usaha rintisan memiliki tujuan untuk mendapatkan profit dan tetap berkelanjutan di masa depan. Untuk mengetahui usaha rintisan tetap berkelanjutan di masa depan maka dibuat model simulasi dengan pendekatan sistem dinamis. Langkah yang dilakukan dalam penelitian ini berdasarkan pendekatan simulasi sistem dinamis antara lain identifikasi dan definisi masalah, konseptualisasi sistem, formulasi model, simulasi model, analisa kebijakan dan implementasi kebijakan. Hasil dari penelitian ini diketahui bahwa hingga periode 100 (April 2028), usaha rintisan kue tradisional tetap berkelanjutan dengan tetap menghasilkan profit setiap bulannya. Dilakukan uji skenario dengan melakukan perubahan harga produk/pcs menjadi Rp. 1,500/pcs saat mengalami kenaikan harga bahan baku yang dapat menjadi pertimbangan bagi owner usaha rintisan untuk menaikkan harga saat bahan baku mengalami kenaikan, sehingga usaha rintisan mendapatkan profit dan akan berkelanjutan di masa depan.

Abstract. PT. Helie Furniture Indonesia is a manufacturing company engaged in the furniture industry that produces several types of outdoor chairs made of stainless steel. This research focuses on one type of product, namely this product has the largest percentage of product delays compared to other products, which is 54.55%. In the production process of the radius chair, there are several wastes that exist in the production line, such as defective products and inventory in the form of work in process (WIP) found at the polishing work station. One approach that can reduce waste is Lean Manufacturing. The first step in this research is to find out waste using Value Stream Mapping (VSM) and Waste Assessment Model (WAM). Based on the results of WAM, 3 dominant wastes were obtained, namely defect, excess processing, and transport. Then the root cause of waste is carried out using 5 why's and determining the value of the Risk Priority Number (RPN) using Failure Mode and Effect Analysis (FMEA). The root cause of the problem in each dominant waste that has the highest RPN value will be made recommendations for improvement. There are 3 recommendations for improvement for supervision during the production process, SOP publication, and redesigning the layout on the production line. Recommendations for improvements that have been made can reduce lead time by 101.88 seconds and increase Process Cycle Efficiency (PCE) by 0.46%. Abstrak. PT.
