Abstract

Currently, 80% of conventional energy is used to meet the needs of industry and the general public. Using new, renewable energy from the sun is an effort to mitigate climate change by reducing greenhouse gases (GHG). Al-Jihad Boarding School, an Islamic educational institution with around 1,200 students, is one of the biggest consumers of conventional energy. This study aims to plan photovoltaic solar cells, calculate the amount of power that can be generated, calculate the amount of GHG emission reduction from photovoltaic solar cells and the costs required for installation at Al-Jihad Islamic Boarding School. The planning results were analyzed by adjusting the selection of a 12 KVA inverter, 44 polycrystalline photovoltaic solar cells, and other complementary materials such as cables, MCBs and supports. The amount of power generated from photovoltaic solar cells at the Al-Jihad Islamic Boarding School in Surabaya is 12 kWh. Climate change mitigation efforts by reducing GHG emissions through solar cell photovoltaic planning at the Al-Jihad Islamic Boarding School in Surabaya can reduce CO2 greenhouse gases by 1,200.5 kg, NH4 30.013 kg, and N2O 0.019 kg. The cost required for the installation of photovoltaic solar cells is Rp. 209,850,400.

Abstract

Peningkatan penduduk skala perkotaan dapat meningkatkan jumlah sampah. Jika pengelolaan sampah tidak maksimal dapat menyebabkan pencemaran lingkungan. Salah satu tempat untuk mengelola sampah yaitu TPS 3R. TPS 3R mampu melakukan pengelolaan sampah dari sumber dengan metode dekomposisi dan pengelolaan sampah secara ramah lingkungan. Penelitian ini bertujuan untuk melakukan analisis aspek teknis pengelolaan sampah di TPS 3R Desa Janti. Analisis yang akan dilakukan diantaranya yaitu analisis densitas sampah, timbulan sampah, komposisi sampah, recovery factory sampah, mass balance sampah. Hasil dari penelitian kali ini menunjukkan timbulan sampah yang dihasilkan TPS 3R Desa Janti sebesar 3.822 kg/hari. Material sampah yang dapat diolah kembali (recovery factory) di TPS 3R Desa Janti sebesar 2.085 kg/hari. Total sampah yang tidak diolah dan dikirim ke TPA sebesar 1.912 kg/hari dengan persentase 45,44% dari total sampah yang masuk di TPS 3R Desa Janti. Hasil analisis aspek teknis pengelolaan sampah di TPS 3R Desa Janti yaitu perlu adanya perlakuan tambahan terkait Pemilahan sampah di TPS 3R Desa Janti yang harus dioptimalkan dengan penambahan jenis sampah yang dipilah. Hal tersebut dilakukan untuk mengoptimalkan pengelolaan sampah dalam aspek teknis di TPS 3R Desa Janti.
