Abstract

Medical solid waste management still faces obstacles several problems such as the lack of use of complete personal protective equipment (PPE) by officers and the absence of special routes for transporting waste. This study aims to evaluate medical solid waste management in hospitals. The method used was qualitative with a purposive sampling technique of 10 informants at the location concerned. Data was collected through in-depth interviews, field observations, and document review, then processed and analyzed using a triangulation table of sources and methods. Even though hospitals have SOPs that are socialized to staff, adequate human resources, funds, facilities and infrastructure, not all of them meet the requirements. The waste reduction process has not been implemented, TPHS B3 has been used as a rest area for officers, the sulo has not been closed because medical waste is buried in non-medical waste, and there is no waste transportation route available. The research results show that the management of medical and non-medical waste is not fully in accordance with applicable regulations. Therefore, it is recommended that hospitals reduce waste, monitor waste officers, and provide special routes for transporting waste in accordance with applicable regulations

Abstract

Banyaknya kerusakan bangunan IPAL sepeti pecahnya pipa saluran mengakibatkan IPAL tidak berfungsi sebagaimana mestinya. Dampak kerusakan tersebut diantaranya polusi lingkungan. Tujuan penelitian ini untuk mengetahui faktor yang mempengaruhikeberlanjutan pengelolaan IPAL Komunal di Kota Solok. Metode penelitian kuantitatif dengan responden stakeholders yang berkaitan dengan IPAL. Jumlah responden penelitian ini adalah 84 orang. Hasil penelitian ditemukan 2 faktor yang mempengaruhi keberlanjutan IPAL Komunal yang terdiri dari 11 variabel. 5 variabel paling dominan yaitu Kondisi fisik sarana dan prasarana sistem penyaluran  hanya sebagian yang berfungsi, Kualitas effluent berbau menyengat, merusak estetika dan menganggu ekosistem didekatnya , Kondisi fisik tidak lengkap dan tidak berfungsi, Layout tidak sesuai dengan perencanaan dan tanpa penjelasan dan Lokasi IPAL terlalu dekat dengan rumah warga, dimana tidak terjangkau dengan truk penyedot tinja.

Abstract

Pembangunan infrastruktur jalan memiliki peran penting dalam meningkatkan konektivitas antar wilayah dan mendorong pertumbuhan ekonomi. Namun, keterlambatan dalam proyek konstruksi jalan masih menjadi permasalahan yang sering terjadi dan berdampak pada biaya, kualitas proyek, serta mobilitas masyarakat. Penelitian ini bertujuan untuk mengidentifikasi dan membandingkan faktor-faktor penyebab keterlambatan proyek konstruksi jalan di Kabupaten Solok, dengan pendekatan komparatif antara dua proyek yang mengalami keterlambatan, yaitu pemeliharaan jalan Paninjauan - Kuncir dan pembangunan jalan Muaro–Garabak. Hasil penelitian menunjukkan bahwa 4 faktor utama yang sama penyebab keterlambatan adalah Komitmen pemilik terhadap proyek, Pemantauan dan pengendalian proyek oleh pemilik, Kemampuan pemilik dalam manajemen proyek, dan Pemahaman kontraktor tentang ruang lingkup pekerjaan.

Abstract

The need for non-potable water in vertical residential buildings, especially simple rental flats (rusunawa), continues to increase along with the number of occupants and variations in domestic water use. Dependence on centralized water distribution systems makes these buildings vulnerable to supply disruptions. Therefore, an Internet of Things (IoT)-based Rainwater Harvesting (RWH) system is proposed as an alternative strategy to support sustainable non-potable water supply. This study analyzes rainfall potential, estimates domestic non-potable water demand, designs storage and distribution components, and integrates IoT-based monitoring for water level, pressure, and selected water-quality indicators. The analysis used rainfall data from the nearest relevant rainfall stations for the study area, frequency analysis with the Log Pearson Type III distribution, design discharge estimation using the Rational Method, field observation, and laboratory rainwater quality testing. The results show that the 10-year return-period rainfall is 282.624 mm/day, producing a design discharge of 0.00351 m³/s for a 1-hour rainfall duration. The daily water demand is 3.35 m³, and the proposed system uses an existing 23 m³ Ground Water Tank (GWT) and a 4.40 m³ Roof Water Tank (RWT), supported by pumps, a first-flush diverter, filtration, and a web-based IoT dashboard. Because nitrate, pH, Total Coliform, and E. coli exceed the applicable quality limits, the harvested rainwater is recommended for non-potable uses such as flushing, sanitation, and environmental cleaning after appropriate treatment.
