Abstract

Abstrak Permasalahan pengelolaan sampah anorganik di Desa Benelanlor, Banyuwangi, masih menjadi tantangan besar. Sampah yang tidak terkelola dengan baik menyebabkan pencemaran lingkungan, penumpukan di aliran sungai, serta polusi udara akibat bau yang mengganggu. Meskipun telah tersedia Tempat Pembuangan Sampah Terpadu (TPS 3R), masyarakat setempat merasa terbebani dengan biaya operasional yang tinggi. Oleh karena itu, diperlukan solusi alternatif yang dapat diterapkan secara mandiri oleh masyarakat. Program ini bertujuan membentuk Bank Sampah berbasis digital guna meningkatkan kesadaran masyarakat dan efisiensi pengelolaan sampah. Metode yang digunakan mencakup survei, FGD, pengembangan aplikasi Bank Sampah, sosialisasi, serta pelatihan kepada masyarakat dan pengelola. Mitra dalam kegiatan ini adalah Badan Usaha Milik Desa (BUMDes) Subur Makmur Benelanlor, yang bertindak sebagai pengelola utama Bank Sampah. Program ini melibatkan partisipasi aktif masyarakat, termasuk warga desa dan perangkat desa. Hasilnya, terbentuk sistem Bank Sampah digital yang mendorong masyarakat memilah sampah dan memperoleh manfaat ekonomi serta menciptakan solusi berkelanjutan bagi lingkungan. Kata kunci: bank sampah; desa benelanlor; pengelolaan sampah; BUMDES; TPS. Abstract The issue of inorganic waste management in Benelanlor Village, Banyuwangi, remains a significant challenge. Poor waste management causes environmental pollution, waste accumulation in river streams, and air pollution due to unpleasant odors. Although the Integrated Waste Disposal Site (TPS 3R) is available, the local community feels burdened by its high operational costs. Therefore, an alternative solution that can be independently implemented by the community is needed. This program aims to establish a digital-based Waste Bank to improve community awareness and the efficiency of waste management. The methods used include surveys, Focus Group Discussions (FGD), Waste Bank application development, socialization, and training for the community and managers. The partner in this activity is the Village-Owned Enterprise (BUMDes) Subur Makmur Benelanlor, which acts as the main manager of the Waste Bank. This program involves active community participation, including village residents and local officials. As a result, a digital Waste Bank system was established, encouraging the community to sort waste, gain economic benefits, and create sustainable environmental solutions. Keywords: waste bank; benelanlor village; waste management; BUMDES, TPS.

Abstract

Waste is a problem faced by all countries around the world, including Indonesia. The increasing amount of waste is due to ineffective management. However, some villages in Banyuwangi, including Benelan Lor, are starting to make efforts to manage waste more effectively. Given the rising volume of organic waste generated by the community and its impact on the environment, proper processing is essential, one of which is maggot farming. One challenge faced by partners is the lack of community awareness regarding household waste management. Therefore, raising awareness about effective waste management is crucial, as it can also provide income opportunities for the community. One solution that can be implemented is the farming of Black Soldier Fly (BSF). This initiative begins with surveys, the construction of breeding facilities, and socialization and training on BSF farming. It is hoped that through this activity, partners will be able to manage waste independently and support the economic improvement of the community in Benelan Lor Village.

Abstract

This study aims to identify periodic patterns and predict the movement of Coca-Cola (KO) stock prices using Fourier series in a linear regression model. The data utilized includes daily closing stock prices over the 2014-2024 period. A Fourier model with 15 harmonic components was chosen to optimize the balance between prediction accuracy and the risk of overfitting. The analysis results showed an R-squared value of 0.9174, indicating a high capability of capturing stock price variations. The detected price fluctuations reveal significant seasonal cycles and periodic trends. The price forecast for the 2024-2029 period indicates potential higher volatility, influenced by consumer demand dynamics, global economic uncertainty, product innovation, as well as geopolitical factors and climate change. These findings provide insights for investors to develop investment strategies based on the detected stock price fluctuation patterns.

Abstract

This study focuses on forecasting the average air temperature in the city of Mataram by applying the Least Square method to determine data patterns based on historical data. The data used includes the average air temperature from 2019 to 2023, obtained from the BPS Mataram City. Based on the pattern used, the resulting forecasting model for the average air temperature is Ŷ = 27.44 - 0.143X. The forecasted results indicate a gradual decrease in the average air temperature from 2024 to 2030 in Mataram. This trend is reflected by the change in the forecasted average air temperature value in the model, with a rate of -0.143. The model's accuracy is demonstrated by a Mean Absolute Percentage Error (MAPE) of 3.22%, indicating a very good level of accuracy in forecasting the average air temperature for the predicted years. This research is expected to provide useful information for the community and relevant stakeholders in Mataram to anticipate temperature changes and to plan for better climate adaptation policies in the future.
