Abstract

This study intends to analyze methane gas emissions resulting in landfill procedures. The magnitude of the impact of methane gas emissions on global warming from the waste sector, it is necessary to calculate the potential amount of methane gas emissions of Padang city waste in the Air Dingin Landfill so that it can be used for new energy potential as an alternative energy to replace fossil fuels no longer as a contributor to global warming. In this study, the methodology contains systematic steps in researching to achieve research objectives, namely conducting preliminary studies and literature studies, formulating problems, and setting research objectives as well as how to collect and obtain research data. The result of this study is that the Air DIngin Landfill in Padang City is still processing open dumping, with land that has been operated around 50% of the existing land area. The high operational costs are one of the reasons the sanitary landfill system cannot be done by the Padang City Government. Methane gas produced from 2020 - 2031 in the Air Dingin Landfill is produced from scenario 1 (waste directly landfilled) which is 43,289 gigagrams of CH4 or 43,289 tons of CH4 emissions. CH4 emission scenario 2 (waste reduction by waste pickers in landfill) produced 43,267 gigagrams or 43,267 tons of CH4. CH4 emission scenario 3 (Reduction of waste at source, in the region, and in landfill) produced 40,944 gigagrams CH 4 or 40,944 tons of CH4. After converting methane gas into electrical energy, the potential electricity in scenario 1 is 84.15 megawatts, scenario 2 is 84.10 megawatts and scenario 3 is 79.59 megawatts in 2031.

Abstract

Medical waste is any type of waste containing infectious materials or infectious materials originating from health facilities. Medical waste management in Indonesia is still considered not optimal. Several categories or types of medical waste include infectious, pathological, radioactive, pharmaceutical, cytotoxic and sharps waste characteristics. Waste minimization is an effort to reduce the volume, concentration, toxicity (toxicity), and the level of danger that comes out of the environment by reducing the source or utilization of the waste itself. There is still little research on the minimization of medical waste. By collecting ampoules for one month as much as 502.898 grams and a total of 31.902 grams of sharps waste, the potential for ampoule waste minimization to sharps waste is 1.60%. Ampoules and Durham showed the same results in the presumptive and confirmatory tests for the presence of coliforms in the well, so the ampoules could be used as a substitute for Durham tube bacteria. ampoule waste in hospitals can be minimized, while for laboratories that perform MPN coliform meton testing can utilize ampoule waste so as to reduce the cost of purchasing Durham tubes.

Abstract

Waste management at the community level through waste banks has been carried out involving collaboration between the local government, the community and the private sector in Padang City. This research aims to analyze the existing conditions of waste management through waste banks in Padang City. The research was carried out by means of field observations, distributing questionnaires to the community and interviews with related parties such as the managing government, namely DLH of Padang City and waste bank administrators. The results of research through distributing questionnaires show that 81% of the people of Padang City knew about the waste bank, but only 22.2% of the people actively participate in waste bank activities. This is caused by a lack of public knowledge about selecting waste according to type, waste segregation has not been carried out at the source of the waste and the role of the community in waste management to create a clean and healthy environment. On the other hand, it is also known that cooperation between DLH of Padang City, local waste bank managers, waste bank customers and also collectors or third parties has not been integrated.

Abstract

Kota Sungai Penuh tidak memiliki lokasi Tempat Pengelolaan Akhir (TPA) sampah. Pemerintah menyewa lahan warga untuk dijadikan Tempat Penampungan Sementara (TPS) di Desa Renah Padang Tinggi dengan luas 1,6 Ha. Kondisi ini membutuhkan upaya pengurangan sampah secara optimal dari sumbernya. Salah satu sumber sampah terbesar adalah sampah rumah tangga yang bisa dikelola di bank sampah dan TPS 3R. Berdasarkan data Dinas Lingkungan Hidup (DLH) Kota Sungai Penuh tahun 2024, terdapat 1 unit bank sampah dan 16 unit TPS 3R yang berpotensi mengurangi sampah menuju TPA jika dikelola dengan baik. Tujuan penelitian ini adalah untuk menyusun rencana strategi peningkatan pengelolaan bank sampah dan TPS 3R di Kota Sungai Penuh. Pendekatan yang dilakukan untuk menentukan strategi yaitu Strength Weakness Opportunity Threat (SWOT) dan Analytical Hierarchy Process (AHP). Analisis SWOT dilakukan dengan menghitung nilai bobot dan rating dari hasil penetapan faktor internal dan eksternal yang menghasilkan strategi diversifikasi yaitu memaksimalkan kekuatan untuk mengatasi atau mencegah ancaman. Analisis AHP menghasilkan strategi prioritas pengelolaan sampah pada bank sampah dan TPS 3R yaitu yaitu memaksimalkan pengoperasian TPS 3R dan Bank Sampah yang terintegrasi dengan BUMDes dengan nilai bobot 0,28.

Abstract

Avocado starch has gained attention as a potential bio-based material due to its unique features that make it suitable for forming biofilms. This work thoroughly examines the changing field of research focused on using avocado starch for biofilm applications. It uses VOSviewer, a tool for analyzing bibliometric data, to uncover important insights using a database of Scopus-indexed journal publishers. This study aimed to determine research trends on the use of avocado starch for biofilm production. The Scopus database collected information on research trends in the use of avocado starch for biofilm production. To obtain search results, subject categories with titles, keywords, and abstract criteria from the use of avocado starch extraction, biofilm/bioplastic production, and biocomposite were used as a reference. Using VOSviewer, search result extraction was performed. The results of bibliometric mapping were then further evaluated. The findings of the bibliometric study are demonstrated through network visualization, overlay visualization, and density visualization. The findings indicate that starch produced from avocados has the potential to be a viable resource for manufacturing biofilms. However, further investigation is required to enhance the overall quality of the produced biofilm.
