Abstract

This research aims to determine the effect of the sodium hydroxide (NaOH) neutralization process in semi virgin red palm oil on free fatty acid levels, dirt levels and water content. Efforts to obtain the best quality red palm oil can be done by administering sodium hydroxide (NaOH). The method used in this research was a non-factorial Completely Randomized Design (CRD) using the chemical Sodium Hydroxide (NaOH) with concentrations of 3%, 4% and 5% of the sample weight. Each chemical and its concentration was repeated in 3 repetition units. The types of observations carried out are ALB levels, dirt levels, water content. The data obtained were analyzed using the Anova Test and Duncan's Test. The research results show that sodium hydroxide (NaOH) can reduce ALB levels by up to 0.13%. In the Dirt Content parameter, the chemical sodium hydroxide (NaOH) can reduce the dirt content by 0.0024% and in the Water Content parameter, the use of the chemical sodium hydroxide (NaOH) can reduce the water content by up to 0.0027%. With the conclusion that the use of the chemical resist sodium hydroxide as an efficient catalyst in the SVCPO neutralization process.

Abstract

Cascara is made from coffee skins and is starting to be known as a health drink. There are four varieties of coffee cultivated in Karo and the skins are used as Cascara. The aim of this research was to determine the phenol levels associated with the properties of Cascara originating from varieties cultivated in Karo. The method to obtain the phenol content in Cascara uses maceration using 85% methanol on dry Cascara. The research results show that Cascara which comes from Andungsari coffee skins has the highest phenol content, namely 8.0952 mg GAE/g and the lowest in Cascara Siagarrutang at 5.1515 mg GAE/g.

Abstract

Penelitian ini bertujuan untuk memperoleh data komposisi fraksi-fraksi pada cairan screw press dan kadar minyak dan non minyak pada ampas screw press. Metode yang digunakan adalah penambahan air panas delusi pada screw press dengan temperature 85oC, 90oC, 95oC dengan debit 1,8 ton/jam. Parameter yang dimati adalah fraksi dan kadar minyak, emulsi, air dan NOS. Hasil penelitian menunjukkan bahwa semakin tinggi temperature air delusi maka semakin besar fraksi minyak pada cairan dan berbanding terbalik dengan kadar minyak pada cake (fiber) yang semakin rendah. Semakin tinggi temperatur air delusi maka semakin rendah fraksi NOS pada cairan dan fiber. Fraksi minyak tertinggi pada cairan press terdapat pada air delusi 95oC (58,00%) dan terendah pada cairan hasil air delusi 85 oC (37,67%).

Abstract

The empty bunch press is a tool that extracts oil from empty palm fruit bunches to reduce oil losses. This study aimed to assess the machine's effectiveness and productivity, measure oil content in the residue, and evaluate the quality of the oil bunch press . A quantitative descriptive method was applied through 14 days of observation at a palm oil mill laboratory. Results showed that the oil content in empty bunches was 6.36%, that of residue was 1.12%, and that of oil bunch press  was 5.23%. Input weight was 4,071 kg/hour, output 1,833 kg/hour, and extracted oil 95.87 kg/hour. The machine's effectiveness was 82.23%, and productivity was within a 5–6 tons/hour capacity. Oil bunch press quality tests showed 5.24% FFA, 0.41% moisture, and 0.12% impurities. Although losses and oil quality exceeded standard limits, the oil bunch press  will be refined before blending with production oil.

Abstract

Tujuan penelitian ini adalah untuk memperbaiki parameter mutu limbah cair pabrik kelapa sawit (PKS), yaitu Chemical Oxygen Demand (COD). Metode yang digunakan adalah membuat bioadsorben dengan memanfaatkan pelepah kelapa sawit untuk menyerap (adsorpsi) COD. Pelepah sawit dilakukan pengarangan dengan cara pirolisis. Arang yang terbentuk dilakukan aktivasi dengan menggunakan aktivator H2SO4. Aktivator yang digunakan dibuat dalam berbagai variasi, yaitu; 20%, 25% dan 30% dan tanpa menggunakan aktivator (kontrol). Desain penelitian adalah RAL (rancangan acak lengkap) non faktorial dengan 4 taraf perlakuan. Parameter yang diamati adalah COD, pH dan bentuk fisik bioadsorben dengan menggunakan SEM. Hasil penelitian menunjukkan variasi kosentrasi terbaik untuk aktivasi bioadsorben adalah konsentrasi 30% dengan rata-rata nilai COD limbah 11.735 mg/l dan pH rata-rata 5,9. Sedangkan untuk uji bentuk dan morfologi perlakuan 30% memberi hasil pembentukan pori-pori yang lebih banyak dan lebih besar serta merata dibandingkan dengan bioadsorben yang tidak dilakukan proses aktivasi.
