Abstract

Waste cooking oil (jelantah) is frying waste from palm oil that has been used repeatedly and continuously.This type of waste cannot be disposed of directly into the environment because it can contaminate the surrounding area. Waste cooking oil can be used as a raw material for activated charcoal dishwashing cream soap. Activated charcoal solid soap is prepared by adding waste cooking oil to 137 gr NaOH, 500 ml water, 2.5 gr NaCl, 1 gr 4Na-EDTA, and 40 gr finely activated charcoal. Diced solid soap is then dissolved in ethanol 70% and glycerin to form a paste (cream). The results of this study indicate that the chemical characteristics of cream soap from used cooking oil are not different from those made from new palm cooking oil. The water content of activated charcoal cream soap from used cooking oil is 40.60% and pH 10.6 and the water content of new palm cooking oil is 40.32% and pH 10.6. It was concluded that waste cooking oil can be used as an ingredient in activated charcoal dishwashing cream and provides more economic and environmental benefits. ABSTRAK Minyak goreng bekas (jelantah) merupakan limbah penggorengan dari minyak sawit yang telah digunakan secara berulang dan terus menerus. Jenis limbah ini tidak bisa langsung dibuang ke lingkungan karena dapat mencemari daerah sekitarnya. Minyak jelantah dapat dimanfaatkan sebagai bahan baku sabun krim cuci piring arang aktif. Sabun padat arang aktif dibuat dengan cara penambahan minyak jelantah dengan 137 gr NaOH, 500 ml air, 2.5 gr NaCl, 1 gr 4Na-EDTA, dan 40 gr arang aktif halus. Sabun padat dipotong dadu kemudian dilarutkan dengan etanol 70% dan gliserin menjadi pasta (krim). Hasil penelitian ini menunjukkan bahwa karakteristik kimia dari sabun krim dari minyak jelantah tidak berbeda dengan sabun yang berasal dari minyak goreng sawit baru. Kadar air sabun krim arang aktif dari minyak jelantah yaitu 40.60% dan pH 10.6 serta kadar air dari minyak goreng sawit baru 40.32% dan pH 10.6. Disimpulkan bahwa minyak jelantah dapat digunakan sebagai bahan krim cuci piring arang aktif dan memberi manfaat lebih terhadap ekonomi dan lingkungan.

Abstract

Waste has become a problem in city/regency. The waste produced originates from daily activities. The study was conducted between June and October. The aim of this research was to analyze the level of knowledge and participation of students as the younger generation in waste management. Data were obtained using questionnaires administered to 177 young participants. The obtained data were descriptively analyzed. The results showed that 87% of the students knew the importance of processing the waste produced so as not to pollute the environment. However, only 32% had processed waste. The processing includes converting organic waste into compost or eco-enzymes.

Abstract

The increasing population in Bogor City, especially in the Tanah Baru area, leads to an increase in the volume of domestic wastewater and municipal waste such as chicken eggshells. Chicken eggshells have the potential to be used as an environmentally friendly biocoagulant to reduce pollutant load, but their effectiveness on domestic wastewater still needs to be studied. This study aims to analyze the effect of adding chicken eggshell biocoagulant on changes in pH, TDS, and conductivity parameters of domestic wastewater and compare it with the conventional coagulant polyaluminum chloride (PAC). The methods used include preparing chicken eggshell powder through washing, drying, grinding, sieving, and chemical activation, then applying it to wastewater samples at a dosage of 50 g/500 mL and comparing it with PAC at a dosage of 1 mL/500 mL using the jar test. The results show that adding chicken eggshell biocoagulant did not significantly reduce pollutant load, even causing an increase in TDS and conductivity, while PAC was able to improve wastewater quality with much lower increases in TDS and conductivity, and the pH remained within the quality standard range. These findings indicate that chemically, chicken eggshells are more suitable for use as an adsorbent or support material in coagulation systems than as the primary coagulant in domestic wastewater treatment.
