Abstract

Selama pandemi Covid-19 diperlukan ruang isolasi untuk menekan penyebaran virus. Di samping itu, penggunaan alat pelindung diri (APD) sekali pakai menjadi hal yang berpotensi merusak lingkungan. Salah satu cara untuk mengurangi dampak tersebut adalah melakukanr recycle limbah APD menjadi sandwich panel. Tujuan dari penelitian ini adalah untuk menganalisa hasil proses solidifikasi limbah APD menjadi sandwich panel. Variasi penelitian ini terdiri dari 4 variasi dimana memiliki waktu pengerasan 4 hari dengan beban 81 kg, 9 hari dengan beban 53 kg, 12 hari dengan beban 75,9 kg, dan 5 hari dengan beban 206 kg. Hasil uji kuat lentur terbesar terjadi pada sampel 5 hari dengan beban 206 kg menghasilkan nilai sekitar 0,003 Mpa. Uji ketahanan panas dan uji porositas air sampel tersebut juga baik dibandingkan dengan sampel lain.

Abstract

The potential for the use of coconut pulp as biodiesel fuel in Indonesia is very large because Indonesia is one of the largest coconut producing countries in the world. One of the conversion methods used to convert coconut pulp into biodiesel is the transesterification method using various catalysts. Based on several literature studies conducted, the yield produced using a CaO catalyst is 96.43% and using a KOH catalyst can reach up to 98.23% with the help of a microwave. The results of a survey that has been conducted on 30 grated coconut traders in various markets, the average coconut pulp produced every day is 20 kg/seller/day. The potential of biodiesel produced from the average amount of coconut dregs can reach up to 3.04 L using a KOH catalyst.

Abstract

Urban sanitation remains a critical public health issue, with community participation recognized as a key factor in the success of sanitation programs. This study aims to explore the multi-dimensional factors influencing community participation in the urban setting of Koja. Through a mixed-methods approach, including surveys, interviews, and observational studies, we investigated how socio-demographic factors such as age, gender, income, and occupation, as well as aspects of sanitation governance, infrastructure, and educational interventions, interplay to affect community engagement. The study revealed that while infrastructure and access are crucial, socio-economic and gender-related barriers significantly impact participation levels. Educational level emerged as a strong predictor of engagement, indicating that awareness and knowledge play a critical role in motivating community involvement. Furthermore, sanitation governance and the quality of policies and monitoring were found to be instrumental in shaping public attitudes towards participation. The research highlights the necessity for integrated and inclusive sanitation policies that address the local context and socio-economic diversity of urban populations. The findings underscore the importance of targeted educational campaigns and the fostering of collaborative community relationships to enhance participation in sanitation programs. This study contributes to the discourse on urban sanitation by providing a nuanced understanding of the complex factors at play in community-based sanitation efforts, offering insights for policymakers to improve public health outcomes.
