Congestion that occurs in the Sudirman area of economic impact on society. Congestion can lead to a reduction in income and decrease the economic benefits for workers who work in the Sudirman. The decline in the perceived economic benefits of the workers can be called with a loss. Losses felt by workers is the value of wasted fuel loss due to increased purchases of fuel oil (BBM), a decrease in productivity in the form of wasted time akbitat jammed seen from income and working time. In addition, there is a loss of value where there is a decline in the health of the costs incurred for treatment due to declining health and psychological pressure value losses due to traffic. Total economic losses due to the impact of congestion on Jl. Sudirman Rp 19,716,239,573,128 / year. The loss is derived from the value of inefficiency fuel oil (BBM) Rp 15,008,423,787,414 / year, the value of reductions in labor productivity Rp 2,871,644,285,714 / year, the value of psychological distress as a result of congestion Rp 525.800.000.000/tahun, and health value of USD 1,310,371,500,000 / year.Key word : Congestion, Economic Losses, Inefficiency, Jakarta ABSTRAK Kemacetan yang terjadi di Jakarta, khususnya di daerah Jalan Sudirman berpengaruh pada ekonomi masyarakat. Kemacetan ini telah berdampak pada pengurangan penghasilan dan penurunan manfaat ekonomi bagi pekerja yang bekerja di daerah Sudirman. Kerugian yang sangat dirasakan para pekerja adalah nilai kerugian dari pemborosan bahan bakar akibat peningkatan pembelian bahan bakar minyak (BBM), penurunan produktivitas berupa waktu yang terbuang akibat kemacetan.

PT. Y is a construction service company that has a Stop Work Authority (SWA) policy as a form of prevention against work accidents. Based on preliminary survey findings data, there were four incidents of unsafe actions and unsafe conditions that were not given stop work intervention. This shows that there are problems in implementing the Stop Work Authority (SWA) policy. Therefore it is necessary to find the root of the problem so that further alternative solutions to problems can be found related to the implementation of the Stop Work Authority (SWA) policy. The purpose of this study is to describe and find in- depth information about the application of the Stop Work Authority (SWA) program in Architecture and MEP (Mechanical, Electrical, and Plumbing) work in the X Apartment Project PT. Y Depok City with qualitative methods. In this study the sample was selected using purposive sampling to obtain two main informants and seven triangulation informants. The instruments used in this study were in- depth interview guidelines and observation sheets. From the interviews it was found that the project personnel did not fully know the points of the Stop Work Authority (SWA) policy, there were still project personnel who had low expertise in stopping work interventions, project personnel had good motivation due to the encouragement factor from PT. Y and the same background, supervision is considered not optimal because it only focuses on violations of unsafe actions and unsafe conditions, and the use of SWA forms is only done by HSE staff. PT. Y still needs to optimize communication and oversight of the Stop Work Authority (SWA) policy and ensure that all personnel have the knowledge and expertise regarding the provision of stop work interventions.

With that background, this research underscores the importance of a circular economy approach in addressing waste issues, in line with Law No. 5 of 2008 on waste management. This approach has the potential to create positive impacts on the economy, environment, and society, such as an increase in Gross Domestic Product (GDP), a reduction in waste volume, and the creation of jobs. This research aims to explore the urgency and potential of the circular economy approach in waste management in Banten Province, as well as to identify effective methods for implementing the 5R concept (Reduce, Reuse, Recycle, Recovery, and Repair) as an effort to close the waste cycle. Through an analysis of data from the Population Administration (Adminduk) and the National Waste Management Information System (SIPSN), as well as reports from The Indonesia Olefin, Aromatic & Plastic Industry Association (INAPLAS) and the Central Statistics Agency (BPS), this research notes an increase in waste volume in Indonesia, particularly plastic waste that pollutes the environment, including the sea. The proposed method to achieve this goal is the establishment of a waste bank as part of social engineering to raise public awareness about waste sorting and to utilize the economic value of waste. The waste bank is expected to serve as a collection and education point for the community in practicing the 5R concept. Additionally, the application of the 5R principles from the source of waste is also considered crucial in addressing the waste problem comprehensively and integratively. The aim of this research is to understand, identify, and analyze how the concept of "closing the loop" is applied in the circular economy model to minimize waste accumulation directly.It is hoped that this research can contribute to the understanding and implementation of the circular economy approach in waste management in Banten Province, as well as offer new perspectives in addressing the challenges faced in implementing the 5R concept.

This study aims to conduct a financial feasibility study of Perum DAMRI's business in the Serang branch with a focus on the transportation routes of Tanjung Lesung and Sawarna national tourism strategic areas. The study combines cost analysis, economic benefits, and financial aspects to evaluate DAMRI's operational performance on these routes. Through cost analysis, it was found that several factors such as vehicle operating costs, fuel, terminal levies, and tire replacement costs have an impact on DAMRI's profit margin. Furthermore, the economic benefit analysis shows that DAMRI can make a positive contribution to the national tourism area by providing better transportation access, but the results still need to be improved.However, when looking at the financial aspects, the two-year Net Present Value (NPV) analysis shows that DAMRI incurred losses in this project. A negative NPV, especially with a discount rate of 12.5%, indicates that the project did not achieve financial viability within the first two years of operation. However, the Internal Rate of Return (IRR) analysis reveals that the project has the potential to generate profitable returns, with an internal rate of return of approximately 13.68%. This suggests that if DAMRI can maintain or improve its operational efficiency, the project has the opportunity to be financially successful in the future. In conclusion, from various analysis perspectives, including BCR, NPV, and IRR, this DAMRI route business is currently not achieving the expected financial viability. Therefore, effective strategies and efforts are needed to ensure the viability and sustainability of DAMRI's operations on this route. Strategic measures could include improving operational efficiency, monitoring and controlling costs, and improving service management. More specific suggestions could involve improvements in cost management, fleet renewal, increased tourism promotion, cooperation with related parties, and the development of services that better suit passenger needs. With concerted efforts, DAMRI can maximize its business potential in Tanjung Lesung and Sawarna tourism areas and achieve better financial viability.

Kebutuhan garam nasional Indonesia mengalami peningkatan seiring pertumbuhan jumlah penduduk, sementara produksi garam dalam negeri belum mampu memenuhinya sehingga dilakukan impor garam. Kecamatan Pangenan, Kabupaten Cirebon merupakan salah satu sentra produksi garam rakyat yang menerapkan tiga teknologi produksi garam, yaitu teknologi tradisional, geomembrane, dan tunnel. Penelitian ini bertujuan untuk membandingkan kualitas garam yang dihasilkan berdasarkan teknologi yang digunakan serta menganalisis efisiensi saluran pemasarannya. Metode analisis yang digunakan meliputi analisis deskriptif dan kuantitatif melalui perhitungan margin pemasaran, farmer’s share, dan rasio keuntungan terhadap biaya pemasaran. Hasil penelitian menunjukkan bahwa garam yang dihasilkan dari teknologi tradisional tergolong dalam kualitas III berdasarkan warnanya, geomembrane kualitas II, dan tunnel kualitas I. Saluran pemasaran 1 merupakan saluran pemasaran yang paling efisien untuk garam hasil produksi teknologi tradisional dan geomembrane yang ditunjukkan oleh marjin pemasaran yang rendah serta nilai farmer’s share dan rasio keuntungan terhadap biaya yang tinggi. Adapun garam hasil teknologi tunnel hanya dipasarkan melalui saluran pemasaran 2 karena keterbatasan jumlah petambak yang menggunakan teknologi tersebut. Indonesia’s national demand for salt continues to rise in line with population growth. In contrast, domestic salt production has not been able to meet this demand, resulting in the need for imports. Pangenan Subdistrict, Cirebon Regency, is one of the centers of community-based salt production that applies three types of production technologies: traditional, geomembrane, and tunnel. This study aims to compare the quality of salt produced based on the technology used and to analyze the efficiency of the marketing channels. The analytical methods employed include descriptive and quantitative analyses, as well as the calculation of marketing margins, farmers’ share, and benefit-cost ratio. The results show that salt produced using traditional technology is classified as grade III based on its color, geomembrane as grade II, and tunnel as grade I. Marketing channel one is identified as the most efficient for salt produced using traditional and geomembrane technologies, as indicated by its low marketing margin and high farmers’ share and benefit-cost ratio. Meanwhile, salt produced using tunnel technology is only marketed through channel two due to the limited number of salt farmers using this technology.

This research aims to analyze community empowerment through the development of creative economic entrepreneurship based on fish farming in Pandeglang Regency. The method used is a descriptive qualitative approach with data collection techniques including observation, in-depth interviews, and documentation of fish farmers and relevant institutions. The research results show that most people still practice fish farming conventionally and have not yet developed many creative and innovative aspects in their businesses. Nevertheless, various forms of creative economic enterprises have emerged, such as fish floss, fish skin crackers, and other processed products, which are largely driven by youth and women's groups. This business has proven capable of increasing community income and independence. However, its development still faces various constraints, such as limited capital, low entrepreneurial literacy, narrow market access, and suboptimal farmer institutions. Therefore, strategies that can be implemented include digital marketing and business management training, strengthening local branding, triple helix collaboration, business digitalization, and establishing a creative house for fishing villages. The conclusion of this study confirms that community empowerment through creative economic entrepreneurship in fish farming has great potential to be a solution for improving community welfare if supported by targeted, collaborative, and sustainable strategies.

Sistem perdagangan pangan dunia menyebabkan produk pangan di dalam negeri sulit dikendalikansebagai akibat transmisi dari situasi harga internasional. Berbagai permasalahan di dalam negeri seperti produksi dan distribusi menyebabkan harga pangan seperti beras, kedelai, daging ayam, cabai dan bawang merah berfluktuasi. Pemerintah daerah termasuk Kota Bogor memiliki peran penting dalam menjaga dan meredam fluktuasi harga yang terjadi khususnya kebutuhan pangan masyarakat. Pemerintah daerah mempunyai peran yang sangat strategis dalam pengelolaan fluktuasi harga, terutama dalam manajemen pasokan barang dengan memadukan kebijakan fiskal daerah, pusat, dan kebijakan moneter. Hampir semua komoditas pangan mengalami tekanan harga luar biasa saat terjadi panen raya. Ironisnya, kita tidak berdaya menahan harga komoditas pangan saat pasokan dalam negeri menurun. Penelitian ini memberi gambaran bagaimana pola perubahan harga pangan yang terjadi seiring dengan perubahan kapasitas produksi, musiman, kenaikan permintaan, dan juga momen-momen tertentu atau peristiwa lainnya. Analisa fluktuasi harga pangan dilakukan dengan menghitung tren harga MoM (Dari Bulan ke Bulan) dan membandingkan harga rata-rata dengan harga modus pada tahun tersebut. Hasil penelitian menunjukkan bahwa faktor yang menyebabkan terjadinya fluktuasi harga pangan adalah pasokan komoditas, kenaikan biaya input produksi, peningkatan permintaan komoditas, kondisi cuaca di lokasi produksi pertanian, adanya kebijakan pembatasan impor, dan permintaan di tingkat internasional. Dari struktur biaya pembentuk harga, biaya penyusutan dan biaya transaksi dapat diturunkan sehingga menjadi lebih efisien. Kebijakan utama yang dapat dilakukan dalam mengatasi kenaikan harga pangan adalah dengan memperluas tupoksi Perumda Pasar Pakuan Jaya untuk dapat melakukan pengendalian harga pangan melalui operasi pasar, penyediaan stok komoditas World food trade makes it challenging to control domestic food products due to the influence of international price trends. Various issues within the country, including production and distribution, lead to fluctuations in the prices of essential food items such as rice, soybeans, chicken meat, chili, and shallots. Local governments, including the City of Bogor, play a vital role in managing price fluctuations, primarily through coordinating regional, central, and monetary policies to ensure a stable supply of goods—most food commodities experience price pressure during harvest seasons. Unfortunately, controlling food prices becomes difficult when domestic supply decreases. This study provides an overview of the patterns of food price changes, considering variations in production capacity, seasonality, increased demand, and other specific events. The analysis involves calculating the Month-to-Month (MoM) price trends and comparing the average price with the model price for each year. The results indicate that fluctuations in food prices are influenced by factors such as commodity supply, rising production input costs, increased demand for commodities, weather conditions at agricultural production sites, import restrictions, and international markets. By optimizing cost structures in price formation, it is possible to reduce depreciation costs and transaction costs for increased efficiency. One key policy to address rising food prices is expanding the functions of Perumda Pasar Pakuan Jaya to include market operations and the management of commodity stocks, enabling better control over food prices.

The problem of organic waste can be solved by applying circular economy principles, namely in waste management using black soldier fly (BSF) maggots. These larvae can decompose organic waste into compost that can be used in agricultural activities. The results of adult larvae can be used as feed in livestock and fish because they contain high protein. The objectives of this study are (1) to identify the amount of organic waste absorption with BSF larval farming business, (2) to analyze the financial feasibility of cultivation in BSF Maggot Cultivation business units in Balaraja and in Tunas, (3) to analyze business efficiency in animal husbandry and fisheries through a circular economy system in the use of BSF larval feed. The research used descriptive-quantitative analysis, financial feasibility analysis, and business efficiency analysis. The results showed that the amount of waste absorption from larval farming business activities reached 430.7 tons/year, with the total land area needed for cultivation being 137,855 m2. The results of the business financial feasibility study show that the Tunas and Balaraja Units are feasible because they have met the eligibility criteria for NPV > 0, Net B/C > 1, IRR > interest rate, and PP > the life of the project. Business efficiency proves that fisheries and livestock business activities integrated into BSF larval cultivation are more efficient in spending on the cost of commercial feed used and provide higher profits in their businesses. Keywords: business efficiency, BSF, circular economy, financial feasibility, maggot black soldier fly, organic waste
