Abstract

Abstrak: Analisis komposisi sampah SMP Kota Mataram dilakukan dengan memilah jenis sampah seperti plastik, kertas, logam, organik, kaca, tekstil, karet, dan lainnya. Hasil penelitian menunjukkan bahwa: - Rata-rata timbulan berat sampah adalah 0,05 kg/orang/hari, dengan nilai tertinggi terjadi pada SMPN 24 Mataram, SMPN 18 Mataram, dan SMP Muhammadiyah Mataram. Rata-rata timbulan volume sampah adalah 0,18 liter/orang/hari, dengan nilai tertinggi terjadi pada SMPN 18 Mataram. Komposisi sampah didominasi oleh plastik dengan persentase tertinggi, diikuti oleh sampah organik dan kertas. Faktor-faktor seperti durasi kegiatan, pola konsumsi, dan jumlah pendapatan mempengaruhi timbulan sampah. Pengelolaan sampah dilakukan dengan mengumpulkan, memilah, dan memprosesnya sesuai jenisnya. Sampah plastik yang dihasilkan memiliki potensi untuk didaur ulang menjadi produk seperti pot bunga atau ecobrick. Sampah organik dapat diolah menjadi pupuk kompos, yang bisa digunakan untuk mengurangi jumlah sampah yang dibuang ke tempat pembuangan akhir. Sekolah dapat menjadi tempat edukasi bagi siswa dalam pengelolaan sampah, termasuk pengolahan sampah organik menjadi pupuk kompos. Abstract: Analysis of the composition of Mataram City Middle School waste was carried out by sorting the types of waste such as plastic, paper, metal, organic, glass, textiles, rubber, and others. The research results show that: - The average weight of waste generation is 0.05 kg/person/day, with the highest values occurring at SMPN 24 Mataram, SMPN 18 Mataram, and SMP Muhammadiyah Mataram. - The average volume of waste generated is 0.18 liters/person/day, with the highest value occurring at SMPN 18 Mataram. - The composition of waste is dominated by plastic with the highest percentage, followed by organic waste and paper. - Factors such as activity duration, consumption patterns, and income influence waste generation. Waste management is carried out by collecting, sorting and processing it according to its type. The resulting plastic waste has the potential to be recycled into products such as flower pots or ecobricks. Organic waste can be processed into compost, which can be used to reduce the amount of waste thrown into landfills. Schools can be a place of education for students in waste management, including processing organic waste into compost.

Abstract: This research aims to measure the generation of solid B3 waste, analyze the sources of production and types of solid B3 waste, analyze existing conditions and identify the management system for solid B3 waste management at Hospital X according to the criteria of PERMENKES No. 7 of 2019 and PERMENLHK No.56 of 2015. This type of research is research that combines quantitative and qualitative approaches. Based on the research results, the total weight of solid B3 waste during the research was 431.29 kg, of which the infectious waste produced was 301.22 kg, while for sharps waste it was 130.07 kg. The average total waste generated is 2.9 kg/day/unit for infectious waste and 1.25 kg/day/unit for sharps waste. Sources of solid B3 waste consist of Outpatient/Polyclinic, Inpatient, Maternity, Postpartum Room, Children's Room, Emergency Room, ICU, Operating Room, Laboratory Unit and Blood Transfusion Unit. The types of waste produced include waste from syringes, lancet needles, gauze, cotton, tissue, gloves, masks, scar bandages, infusion bottles and infusion hoses. Based on the research results, all indicators for assessing solid B3 waste management at Hospital.

Abstract

Abstrak: Penelitian ini bertujuan untuk menganalisis tingkat risiko bencana di Desa Mantar dan merancang jalur evakuasi yang efektif sebagai upaya mitigasi bencana untuk mendukung keberlanjutan pariwisata. Metode penelitian yang digunakan meliputi observasi lapangan, analisis spasial dengan Sistem Informasi Geografis (SIG), wawancara dengan masyarakat dan perangkat desa, serta studi literatur. Hasil penelitian ini menunjukkan bahwa beberapa area di Desa Mantar memiliki kerentanan tinggi terhadap tanah longsor dan gempabumi. Jalur evakuasi yang dirancang mengarah ke titik kumpul aman. Penelitian ini merekomendasikan penguatan infrastruktur evakuasi, pengembangan sistem peringatan dini berbasis masyarakat, serta peningkatan kapasitas masyarakat dalam penanggulangan bencana.Abstract: This research aims to analyze the level of disaster risk in Mantar Village and design effective evacuation routes as a disaster mitigation effort to support tourism sustainability. The research methods used include field observations, spatial analysis using Geographic Information Systems (GIS), interviews with the community and village officials, as well as literature studies. The results of this research show that several areas in Mantar Village have a high vulnerability to landslides and earthquakes. The designed evacuation route leads to a safe gathering point. This research recommends strengthening evacuation infrastructure, developing a community-based early warning system, and increasing community capacity in disaster management.

Abstract

Abstrak: Penelitian ini bertujuan untuk mengkaji pengaruh diameter dan ketebalan pasir silika pada saringan pasir lambat (SPL) dalam menurunkan parameter kualitas air seperti kekeruhan, Total Padatan Terlarut (TDS), pH, Chemical Oxygen Demand (COD), dan Total Coliform pada air Sungai Remeneng, Kecamatan Narmada, Kabupaten Lombok Barat. Air sungai yang digunakan sebagai sumber utama kebutuhan sehari-hari penduduk telah tercemar oleh limbah domestik dan pertanian yang menyebabkan kualitas air menurun. Penelitian dilakukan dengan variasi ketebalan pasir (10 cm, 15 cm, 20 cm, dan 25 cm) dan variasi diameter pasir silika (10 Mesh, 20 Mesh, dan 30 Mesh). Hasil penelitian menunjukkan bahwa SPL mampu menurunkan nilai kekeruhan, TDS, pH, COD, dan Total Coliform secara signifikan. Nilai kekeruhan terbaik diperoleh dari ketebalan 25 cm dan diameter 30 Mesh sebesar 19,8 NTU. Sedangkan penurunan COD dari 104 mg/L menjadi 90 mg/L dicapai pada ketebalan 25 cm dan diameter 10 Mesh, meskipun nilai COD tersebut masih melebihi baku mutu 80 mg/L sesuai dengan Peraturan Pemerintah No. 22 Tahun 2021. Parameter Total Coliform juga mengalami penurunan yang cukup signifikan, dengan hasil terbaik pada ketebalan 25 cm dan diameter 10 Mesh sebesar 230 mpn/ml. Kesimpulannya, saringan pasir lambat dengan variasi ketebalan dan diameter pasir silika efektif untuk menurunkan parameter kekeruhan, TDS, pH, dan Total Coliform, namun untuk parameter COD, meskipun terjadi penurunan, namun hasilnya masih belum memenuhi baku mutu.Abstract: This study aims to assess the effect of diameter and thickness of silica sand on slow sand filters (SPL) in reducing water quality parameters, such as turbidity, Total Dissolved Solids (TDS), pH, Chemical Oxygen Demand (COD), and Total Coliform, in Remeneng River water, Narmada District, West Lombok Regency. River water used as the main source of daily needs of the population is polluted by domestic and agricultural waste, which causes water quality to decline. The research was conducted with sand thickness variation (10 cm, 15 cm, 20 cm, and 25 cm) and silica sand diameter variation (10 Mesh, 20 Mesh, and 30 Mesh). The results showed that SPL was able to significantly reduce turbidity, TDS, pH, COD, and Total Coliform values. The best turbidity value was obtained from a thickness of 25 cm and a diameter of 30 Mesh of 19.8 NTU. While the decrease in COD from 104 mg/L to 90 mg/L was achieved at a thickness of 25 cm and a diameter of 10 Mesh, although the COD value still exceeds the quality standard of 80 mg/L in accordance with Government Regulation No. 22 of 2021. The Total Coliform parameter also experienced a significant decrease, with the best results at a thickness of 25 cm and a diameter of 10 Mesh of 230 mpn/ml. In conclusion, slow sand filters with variations in thickness and diameter of silica sand are effective for reducing turbidity, TDS, pH, and Total Coliform parameters, but for COD parameters, although there is a decrease, the results still do not meet the quality standards.
