Abstract

The need for particle board interiors is still in great demand to be used as wood-sourced interiors. In line with this, currently the problem of waste is still a fairly complex problem, both organic and inorganic waste. Coffee rinds and tofu pulp are organic wastes that have not been optimally utilized. Therefore, research was conducted on the manufacture of particleboard from coffee rinds and tofu pulp with PP plastic adhesive which aims to reduce the rate of deforestation due to tree felling as raw material for interior manufacturing and to control the environment by utilizing waste in the community into functional products. This study aims to determine the best formulation of particleboard made from Polyethylene plastic, coffee bean hulls and tofu pulp. Tofu dregs need to be preserved by soaking the dregs for 48 hours in a 5% glycerol solution and 15% NaCl solution in a 50:50 ratio. Then soaked for 48 hours. soaking 15.121%. To determine a good particleboard formulation, a physical evaluation of the particleboard was carried out including particleboard density test, water absorption test, moisture content test, thickness development test and instrumentation testing using SEM to see the surface structure of the particleboard.  Based on the results of physical testing, the best formulation of particleboard biocomposites was obtained, namely the ratio of 70:30 (% w/b) (70% of tofu pulp and coffee bean skin and 30% of PET plastic) which is in accordance with SNI 03-2105-2006 standards. Biocomposite particleboard formulation 70:30 (% w/b) has a density of 0.60186 gr/cm3, water absorption of 95.395%, moisture content of 2.248% and an increase in thickness after soaking of 15.121%.

Abstract

Peat water is water produced from decaying trees and plants that contain Fe metal with a high content of organic substances. Therefore, effective and efficient peat water treatment is needed to make it suitable for consumption. Bentonite is a natural source of adsorbent but has a fairly low adsorption activity, so bentonite needs to be activated to increase its adsorption ability. Thermal activation was chosen due to its environmentally friendly process and can increase the surface area and adsorption ability of bentonite. This study was conducted to see the effect of bentonite thermal activation with temperatures of 200, 300, 400 and 500˚C in reducing Fe metal content, organic matter, TDS and pH of peat water. The results show that thermal activation of bentonite can reduce the content of these compounds. Thermal activation of bentonite at 500˚C reduced Fe metal content with 66% efficiency and 0.08 mg/g adsorption capacity, 89.6% organic matter with 24,60 mg/g adsorption capacity and TDS 27 mg/l.

Abstract

Peat water, commonly found in peatland regions, often poses a challenge as a water source due to its high content of iron and natural organic matter (NOM). This research investigated the development and application of bentonite–chitosan nanocomposites as an effective adsorbent for reducing iron metal and NOM concentrations in peat water. Chitosan was synthesized from tilapia fish scales through demineralization, deproteinization, and deacetylation processes, then characterized for moisture content (7.4%), ash content (5.4%), and functional groups using FTIR spectroscopy. Bentonite was thermally and chemically activated with sulfuric acid to increase its adsorption capacity. Nanocomposites were prepared with varied bentonite-to-chitosan ratios (90:10, 70:30, 50:50) using sodium tripolyphosphate (STPP) as a crosslinker. FTIR and XRD analyses confirmed the formation of nanocomposites and revealed structural changes post-adsorption, including reduced crystallinity and increased particle size. Adsorption studies showed that the 90%Bt-10%Ch3 formulation achieved the highest iron removal efficiency (68.6%) with an adsorption capacity of 0.084 mg/g. Meanwhile, the 50%Bt-50%Ch3 formulation demonstrated the highest NOM removal efficiency (36.8%) with a capacity of 36.80 mg/g. The results indicate that bentonite is more effective for iron adsorption, while chitosan plays a key role in removing NOM due to its amine and hydroxyl functional groups. This study highlights the potential of utilizing fishery waste and natural minerals to produce low-cost, eco-friendly nanocomposites for improving water quality in peatland environments.

Abstract

Desa Ibru merupakan salah satu desa yang ada di Kabupaten Muara Jambi yang berbatasan dengan Provinsi Sumatera Selatan. Pada Desa tersebut memiliki potensi perkebunanan Sawit dan Karet. Perkebunan sawit pada desa tersebut menghasilkan limbah salah satunya yaitu limbah pelepah sawit. Limbah ini merupakan limbah biomassa yang banyak mengandung unsur Karbon, dimana bisa dikonversi menjadi Biobriket. Biobriket tersebut sangat mendukung program pemerintah tentang Energi baru terbarukan (EBT). Diharapkan biobriket yang akan disosialisasikan dan diajarkan kepada masyarakat Desa Ibru dapat sebagai penganti bahan bakar alternatif untuk skala rumah tangga, home industry, rumah makan ataupun skala industri. Urgensi pengabdian adalah melakukan pemberdayaan masyarakat di Desa Ibru untuk dapat mengolah limbah pelepah sawit menjadi biobriket. Tujuan dilaksanakan kegiatan pengabidan ini, Pertama pelaksanaan tridharma perguruan tinggi. Kedua, peningkatan pendapatan masyarakat Desa Ibru Kabupaten Muara Jambi, Provinsi Jambi dengan mengadakan pelatihan dan pendampingan produksi biobriket dari limbah pelepah sawit. Ketiga, mendukung indikator kinerja utama universitas jambi yaitu IKU 2 dan 7.
