Abstract

Tanaman lontar (Borassus flabellifer L.) tersedia melimpah dan menyebar di Kelurahan Benpasi produknya berupa nira. Salah satu kelompok yang bekerja sebagai penyuling nira adalah Kelompok Tani Nua’f Soeb yang beranggotakan 5 orang. Kelompok ini secara turun-temurun memanfaatkan nira lontar sebagai sumber pendapatan dengan produknya berupa tuak manis (tanpa alkohol), sopi (mengandung alkohol) serta olahan lain berupa gula lempeng. Proses pembuatan gula lempeng sudah berlangsung lama dan dipraktekkan oleh kelompok mitra dengan peralatan dan cara pengolahan yang sederhana dengan penggunaan bahan tambahan berupa detergen. Tujuan dari kegiatan pengabdian ini adalah meningkatkan pengetahuan, pemahaman dan keterampilan kelompok mitra dalam mengolah nira lontar dengan penggunaan bahan tambahan yang aman untuk produk berkualitas. Metode yang digunakan dalam kegiatan adalah penyuluhan dan demonstrasi secara bersama. Disimpulkan bahwa kegiatan pengabdian telah berjalan dengan tahapan-tahapan kegiatannya (persiapan, penyuluhan dan praktek). Pengolahan nira menggunakan bahan tambahan larutan kapur (CaO) dapat menghasilkan gula semut dan gula lempeng berkualitas seperti berwarna kuning kecoklatan, bertekstur halus, beraroma gula, dengan rasa normal dan memiliki tingkat kesukaan yang tinggi. Terjadi peningkatan pemahaman mitra terkait pengolahan nira lontar dari 42% (sebelum kegiatan) menjadi 89% (setelah kegiatan). Kegiatan ini juga menjadi daya tarik serta antusias yang tinggi dari kelompok mitra dengan 100% kehadiran.

Abstract

Manganese is a micro nutrient that plants need in small quantities. Manganese plays an important role as an enzyme activator, including phosphate transfer enzymes and enzymes in the Krebs cycle. The aim of this research was to study the chemical and physical properties of the soil on ex-manganese excavated land in Oelami Village, TTU Regency. This research was carried out in June-September 2022. Analysis of the chemical and physical characteristics of the soil was carried out in the laboratory of the Faculty of Agriculture, University of Timor, and the Laboratory of the Faculty of Agriculture, Nusa Cendana University. This study used a descriptive experimental method which was carried out by survey and continued with laboratory analysis. Soil samples were taken at 5 points based on land use. Based on the results of the analysis of the chemical and physical properties of soil from ex-manganese excavated land, pH was 6.321 (slightly sour), CEC 33.46 me/100g (high), C-organic 0.22% (low), N-total 0.22% (low ), P-total 61.44 mg/100g (high), K-total 71.189 mg/100g (high), Mn-total 19,089 ppm (high), organic matter 0.81% (low), sandy loam soil texture ( sand 81.33%, dust 10.67%, and clay 8.00%), soil water content 8.611% (medium), soil density 1.25 g/cm3 (medium), soil specific gravity 1.47 g/ cm3 (low), and porosity 14.961% (high)

Abstract

Synthesis of cellulose acetate form palm coir (Borassus flabellifer L) waste has been synthesized by varying the time in the delignification process. This study aimed to determine the characteristics of cellulose acetate form palm coir waste (Borassus flabellifer L) and the optimum time for the delignification process. This research was conducted in several stages: sample preparation, cellulose isolation (delignification and bleaching process), and synthesis of cellulose acetate (activation, acetylation, and hydrolysis process). The cellulose acetate obtained was then charatecrized by testing for water content, acetyl content, and degree of substitution and functional grup analysis using a fourier transform infra-red (FTIR) spectrophotometer. In the delignification process, variations of the delignification time were usesd, namely 60, 90, 120, and 150 minutes. Form the results of the study, the characteristics of cellulose acetate in palm coir were optained, namely water content of 0.95%‒2.16%, acetyl content of 37.19%‒40.85%, degree of substitution of 2.2‒2.6 and identification of functional groups using FTIR showed that there was a typical absorption of cellulose acetate on the carbonyl group (C=O) and the ester group (C-O acetyl). The results of variations in the time of the delignification process showed that the optimum reaction time was 120 minutes with the yield of cellulose acetate produced at 254.4%, water content 2.16%, acetyl content 40.85%, degree of substitution (DS) 2.6. the cellulose acetate produced belongs to the type of cellulose diacetate, which can be further utilized in manufacturing threads, membranes, adhesives of films, and mask filters.
