Abstract

The influence of activated natural zeolite catalyst on the further cracking of liquid product’s heavy fraction from plastic waste treatment factory been studied resulting in alternative fuel oil. Natural zeolite from Wonosari, Yogyakarta was activated with 1 M H2SO4 solution. Natural zeolite and activated zeolite were characterized using XRD at an angle of 2ϴ=5-60 degrees. Further cracking process was carried out to study the ratio of catalyst mass of 25 g; 50 g; 75 g; 100 g to 750 mL weight fraction of the factory liquid product. The further cracking product was flame tested, specific gravity measured by gravimetric method and characterized using GC-MS. The calculation of the constituent fuel fractions is also carried out. The performance test of the further cracking product as an alternative fuel was carried out for the generator engine ignition process. The result showed that the activation process using acid was not destroy the zeolite structure. The study of ratio catalyst to liquid waste volume obtained an optimum result at 50 g/750 mL based on the volume of resulted fuel oil with small amount of catalyst. The resulted fuel oil has a density of 0.7908 g/mL with a clear yellow color, and flammable. The GC-MS analysis resulted in fuel oil consisting of 4.11% gasoline, 8.42 kerosene, 75.56% solar, and 11.93% heavy fraction

Abstract

Penelitian tentang analisis kualitas udara ambien sulfur dioksida (SO2) dan nitrogen dioksida (NO2) dilaksanakan dari bulan Januari – April 2022 berlokasi di Distrik Muara Tami Kota Jayapura dengan menggunakan metode kualitatif dan kuantitatif berbasis laboratorium untuk melihat kualitas udara dengan parameter SO2 dan NO2. Data dianalisis dengan menggunakan analisis data univariat untuk melihat nilai minimum, nilai maksimum, dan nilai rata-rata pada setiap variabel penelitian. Hasil Penelitian menunjukkan bahwa Kualitas Udara Ambien Sulfur Dioksida (SO2) dan nitrogen dioksida (NO2) pada Distrik Muara Tami Kota Jayapura berada dalam rentang 0-50 sesuai dengan Peraturan Menteri Lingkungan Hidup dan Kehutanan Republik Indonesia Nomor P.14/Menlhk/Setjen/KUM.1/7/2020 Tentang Indeks Standar Pencemar Udara sehingga dapat dikategorikan ke dalam kageori baik.

Abstract

The study addresses the global problem of pollution caused by the long-term decomposition of plastic waste. It aims to explore the development of biodegradable plastics using Hipere starch and glycerol as a sustainable alternative, emphasizing their potential environmental benefits, abundance, and low cost. The primary materials used are Hipere starch, a natural polymer derived from plants, and glycerol as a plasticizer. These were selected for their compatibility and effectiveness in creating biodegradable plastics. Biodegradable plastics were synthesized through an acetylation process that modifies the starch, aiming to enhance its properties. Various concentrations of starch were tested to evaluate their impact on mechanical and physical characteristics. A soil burial test was conducted to assess biodegradability by monitoring mass reduction over seven days. The resulting plastics exhibited transparency, lightweight properties, insolubility in water, and mold-conforming shapes. Mechanical properties, including tensile strength and elongation, improved with higher starch concentrations. The soil burial test showed consistent mass reductions between 1-3% daily, with the most significant reduction occurring on day 7, demonstrating biodegradability. While improvements were observed, further research is needed to enhance mechanical properties by incorporating additional polymers or alternative modification techniques. This could expand the applications and durability of biodegradable plastics in various industries.
