Abstract

Pyrolysis is a process of chemical decomposition of materials through a heating method in the absence of oxygen or a little oxygen. The utilizing coal as a raw material for making liquid smoke, it is hoped that it will be able to produce pesticides that have economic value and can be used as a termite exterminator. The use of coal as a raw material for making liquid smoke is expected to produce pesticides that have economic value and can be used as a termite repellent. This research aimed to determine the optimum concentration and time of liquid coal smoke as a pesticide against termite insect mortality (Coptotermes curvignathus Holmgren). The method used is the coal pyrolysis process at a temperature of 300 0C. The process of testing the mortality of termites with time and concentration variables. The determination of the liquid smoke content of coal is carried out by qualitative and quantitative analysis. The results showed that the optimum time for termite mortality was 25 minutes with an optimum concentration of 80%, where the termite mortality was obtained by 100%. Based on the results of UV/VIS Spectrophotometer Analysis, the sulfur content of liquid coal smoke was 46.92 mg/kg, and the degree of acidity (pH) was 3.00. The acidity content is high enough to allow pesticides from liquid coal smoke to be widely used in agriculture.

Abstract

Salah satu limbah dapat dimanfaatkan sebagai bioadsorben yaitu limbah mahkota nanas karena mengandung selulosa 71%. Tujuan dari penelitian ini untuk mengetahui pengaruh jenis aktivator pada karbon limbah mahkota nanas terhadap karakteristik bioadsorben meliputi luas area dan gugus fungsional/active site. Arang aktif dari limbah mahkota nanas dengan metode pirolisis pada suhu 400oC selama 2 jam, setelah itu arang yang terbentuk dilakukan penyaringan dan screening ukuran 120 mesh. Tahap selanjutnya yaitu modifikasi, arang dari hasil pirolisis di rendam dalam larutan H3PO4, Sodium Dedocylbenzene Sulfonate (DBS), NaOH dengan dengan variasi konsentrasi (2,3,4,5,6%) selama 2,5 jam dengan suhu 25oC dengan rasio 25 g : 100 ml. Hasil penelitian diperoleh bahwa limbah mahkota nanas dapat digunakan sebagai adsorben melalui proses pengarangan dan aktivasi menggunakan NaOH 2% dan surfaktan DSB 4%, arang aktif dari limbah mahkota nanas teraktivasi NaOH 2% memiliki nilai daya serap iodin yaitu 1015,20 mg/g dan luas area adsorben sebesar 338,92 m2/g Karakterisasi gugus fungsi adsorben terdapat gugus C=C aromatik, C-H alifatik dan -OH yang menjadi gugus aktif sebagai adsorben. Efektivitas adsorpsi dari arang limbah mahkota nanas diperoleh sebesar 91,87% pada arang teraktivasi NaOH 25 dan 90,03% pada arang teraktivasi surfaktan DBS.

Abstract

This community service activity examines the implementation of modern coconut husking technology and coconut husk waste utilization in Balleanging Village, Ujung Loe District, Bulukumba Regency, through the Community Partnership Program (PKM). The research focuses on the Jaya Abadi Farmer Group, consisting of 30 farmers with average land ownership of 0.5-1.5 hectares. The methodology includes location surveys, intensive 4-week training, technology implementation, and program evaluation. Results show significant productivity improvements, with husking capacity increasing from 12-60 to 200 coconuts per hour, reducing processing time per unit from 1-5 minutes to 0.3 minutes, achieving 94% efficiency. Modern technology implementation also reduced labor requirements by 50-67% and minimized workplace accident risks. The coconut husk waste processing education program resulted in the diversification of economically valuable products such as cocopeat, cocofiber, and planting media. Program evaluation demonstrates high technology adoption rates, supported by a comprehensive assistance system covering operational aspects, maintenance, and product development. This technological transformation not only enhances production efficiency but also creates opportunities for sustainable economic development through value-added waste utilization, positively impacting the welfare of coconut farmers in Balleanging Village.

Abstract

Liquid smoke resulting from pyrolysis of durian skin has antibacterial potential which is used as a basic ingredient for making bio hand sanitizer. Durian skin is difficult to degrade because it contains high levels of lignin, cellulose, and hemicellulose compounds, so with the use of durian skin, it is expert that it will be able to reduce durian skin waste. Bio hand sanitizer is formulated with essential oils to reduce the pungent aroma of smoke. This study aims to determine the antibacterial activity and characteristics of the durian skin liquid smoke bio hand sanitizer. This study used the Completely Randomized Design (CRD) method, with a comparison between durian peel liquid smoke and orange peel extract and the addition of 10 mL NaOH (1:3, 1:1,57, 1:1, and 3:1). The results of research based on characteristic tests obtained pH values of 4.81-7.36, viscosity 1392-3664 cps. Formula E (3:1) emerged as the best sample through organoleptic tests on each bio hand sanitizer preparation formula. It exhibited a yellow color, a runny texture, and a smoky aroma with the mixture. The antibacterial test demonstrated that the bio hand sanitizer preparation possessed antibacterial activity, and the resistance diameter for the test bacteria S. Aureus and E. Coli ranged from 21.51 to 31.14 mm
