Abstract

Research has been carried out on the utilization of biomass waste of coconut trunk sawdust using the pyrolysis method to produce two products simultaneously, namely charcoal and liquid smoke. In order to obtain charcoal products with optimum calorific value, it is necessary to understand the optimum pyrolysis conditions. One of the optimum conditions, namely pyrolysis temperature, was studied in this research. Pyrolysis was carried out in a simultaneous pyrolysis reactor at a flow rate of argon inert gas into the reactor of 2 liters/minute and a pyrolysis time of 2.5 hours with pyrolysis temperature variations of 350, 400, 450, and 500°C, respectively. The study showed that the optimum temperature of 400oC was obtained which gave a yield of 34% charcoal with a calorific value of 7229 kcal/kg. Compared to the calorific value of the raw material for coconut sawdust which is 4400 kcal/kg, there was an increase in the calorific value of the pyrolysis product by 64%. Based on the optimum temperature condition, liquid smoke as a by-product was also obtained with a yield of 45%. Charcoal can be used as a solid fuel or as a bioadsorbent in the treatment of liquid waste or clarification of liquid food products such as virgin coconut oil (VCO). Grade 3 liquid smoke can be used as a biopesticide, while grade 1 liquid smoke can be used as a food preservative. Given the benefits of the two pyrolysis products, both of the products from the current research have a promising market value.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas tata kelola pemerintahan daerah berbasis good governance dalam meningkatkan kualitas pelayanan publik di Kota Bontang. Latar belakang penelitian ini didasarkan pada pentingnya implementasi good governance dalam otonomi daerah serta adanya fluktuasi capaian kualitas pelayanan publik yang menunjukkan ketidakkonsistenan kinerja antar Organisasi Perangkat Daerah (OPD). Metode yang digunakan adalah pendekatan kualitatif dengan desain deskriptif analitis. Data dikumpulkan melalui wawancara mendalam, observasi lapangan, dan dokumentasi pada beberapa OPD yang terkait langsung dengan pelayanan publik. Informan dipilih menggunakan purposive sampling yang terdiri dari aparatur pemerintah, pengguna layanan, dan perwakilan Ombudsman. Hasil penelitian menunjukkan bahwa penerapan prinsip good governance di Kota Bontang telah berkembang pada aspek transparansi, akuntabilitas, dan keterbukaan informasi. Implementasi masih belum optimal akibat ketimpangan kualitas layanan antar OPD, rendahnya pemanfaatan sistem pengaduan, serta keterbatasan literasi digital masyarakat. Faktor pendukung utama meliputi komitmen kepemimpinan, kolaborasi lintas sektor, dan digitalisasi layanan. Faktor penghambat meliputi inkonsistensi layanan, lemahnya pengawasan internal, dan belum optimalnya integrasi pengaduan masyarakat. Penelitian ini menyimpulkan bahwa efektivitas tata kelola pemerintahan Kota Bontang berada pada kategori berkembang tetapi belum optimal dan memerlukan penguatan standarisasi layanan serta sistem pelayanan yang lebih responsif.
