Abstract

Briquettes are solid fuels made from a mixture of palm kernel shells and corn cobs. Usually used as an alternative fuel such as firewood, charcoal, or coal. This study aims to determine the best composition for briquette quality. Palm kernel shells are a by-product of palm oil processing, while corn cobs are the part of the corn plant at the top of the stem that functions as a place for corn kernels to grow. Corn cobs are often unused agricultural waste. The study was conducted at the ITSI Process Laboratory, ITSI Physics Laboratory, and PTKI Physics Laboratory with an experimental method using This study used the Completely Randomized Design (CRD) Non-Factorial method using three variations of Comparison (Palm Kernel Shells 75%: 25% Corn Cobs; Palm Kernel Shells 50%: 50% Corn Cobs; Palm Kernel Shells 25%: 75% Corn Cobs) with three repetitions each. With the addition of Tapoika each 20%.. High water content can affect the quality of briquettes, because it can inhibit the evaporation process, combustion, and density of briquettes.

Abstract

The Continuous Settling Tank (CST) is a tank at the clarification station of a palm oil mill used for the sedimentation process of oil, water, and sludge. The optimal performance of the CST is evaluated based on the overflow produced, considering the quality of water content and the level of oil impurities according to standards. Controlling the percentage of impurities in the oil requires an optimal thickness level during collection. The thickness of the fluid layer in the CST tank can be measured using a bamboo stick. However, the bamboo used to measure the fluid thickness is inaccurate because the bamboo inserted into the CST tank, with the expectation that sludge will adhere to it, is often cleaned by the oil layer, and the bamboo has to be inserted repeatedly, making it inefficient. Therefore, it is necessary to create a device to measure oil thickness based on Archimedes' principle, using a float. The objective of this research is to create a measuring device to control the quality of crude oil in the Continuous Settling Tank based on the oil thickness. The design of this research uses two methods: descriptive and experimental. The research results show that after the implementation of the measuring device as a thickness indicator, oil quality control in the CST becomes efficient. With an oil thickness of 50 cm, the average quality of crude oil is observed to be the best, with a water content of 0.45% and an impurity level of 0.49%.

Abstract

Crude Palm Oil is one type of vegetable oil that is extensively utilized in many different industries around the world, one of which is as a basic ingredient for cooking oil products. In Indonesia, Palm oil is among the abundant agricultural commodities. Therefore, palm oil is the right decision to address community needs across a range of domains. Crude palm oil has a high beta-carotene content, an initial compound of vitamin A, which gives the oil a reddish color. The dominant color of red or orange fruits or vegetables is a characteristic of crude palm oil from other types of vegetable oils. This investigation was carried out to examine the impact of adding aromatic medicinal plant extracts on the aroma and taste characteristics of palm oil when high water content increases free fatty acid levels that can cause CPO rancidity. Various experimental methods were used with data obtained from a careful literature review. The final results showed that variations in the addition of these ingredients significantly affected the aroma and taste of palm oil, highlighting the potential for innovation in product development and the food industry with repeated frying processes.

Abstract

Crude palm oil (CPO) merupakan minyak hasil olahan tandan buah segar menjadi minyak dari pabrik pengolahan kelapa sawit, masalah umum pada CPO adalah penurunan kualitas CPO akibat peningkatan konsentrasi asam lemak bebas (ALB). Tingginya kadar asam lemak bebas menyebabkan ketengikan, perubahan rasa dan warna pada minyak. Salah satu faktor penyebab meningkatnya jumlah asam lemak bebas pada minyak adalah hidrolisis dikarenakan jumlah kadar air yang tekandung dalam CPO. Penelitian ini dilakukan untuk mengetahui pengaruh kadar air, suhu dan lama penyimpanan terhadap kenaikan asam lemak bebas. Penelitian ini menggunakan metode Rangcangan Acak Lengkap (RAL) Faktorial dengan menggunakan tiga faktor (persentase air 0,35%, 0,40% dan 0,50%. Suhu 50 oC, 55 oC dan 60 oC. Lama penyimpanan 12 jam dan 24 jam). Hasil penelitian yang telah dilakukan menunjukkan bahwa semakin tinggi kadar air yang terkandung pada CPO maka semakin tinggi kenaikan kadar asam lemak bebasnya. Semakin tinggi perlakuan suhu yang diberikan maka kadar asam lemak bebas yang dihasilkan akan lebih rendah. Semakin lama penyimpanan CPO maka kadar asam lemak yang dihasilkan akan semakin tinggi. Hasil dari anova terhadap perlakuan menunjukkan bahwa perlakuan kadar air berpengaruh sangat nyata terhadap ALB, perlakuan suhu berpengaruh sangat nyata terhadap ALB dan perlakuan lama penyimpanan berpengaruh sangat nyata terhadap asam lemak bebas (ALB). Kata Kunci: Crude Palm Oil (CPO), Asam Lemak Bebas (ALB), kadar air, suhu, lama penyimpanan.

Abstract

This study aims to determine soil pH values using various dilution levels with water (H₂O) and 1 N KCl solution, and to analyze their effects on soil acidity and its implications for soil fertility. Soil pH is an important indicator that influences nutrient availability and plant growth, particularly in oil palm cultivation. The research was conducted in an ITSI Soil Laboratory by mixing air-dried soil with H₂O and KCl in ratios of 1:1 and 1:2.5. The results showed that soil pH mixed with water ranged from 5.3 to 5.8 (slightly acidic), while soil mixed with 1 N KCl had lower pH values, ranging from 4.2 to 4.4 (strongly acidic). The decrease in pH when using KCl solution is due to the exchange of H⁺ and Al³⁺ ions from soil colloids into the solution, resulting in increased soil acidity. This condition can reduce nutrient availability, suppress microbial activity, and potentially lead to toxicity in plants if not properly managed. Therefore, soil pH management through liming is necessary to achieve optimal conditions for plant growth.

Abstract

Each cooking oil has differences, especially in the content of antioxidant compounds. Oil with high antioxidant content can reduce oil damage during the process of use. The content of antioxidant compounds in red palm oil and cooking oil can cause oil damage in red palm oil and cooking oil also varies. The study aims to determine the effect of oil type on antioxidant levels in red palm oil with the deep fat frying method and to determine the difference in temperature affecting antioxidant levels in cooking oil with the deep fat frying method. This study was conducted using the Completely Randomized Design method in factorial form, with 2 treatment factors. The first treatment is the type of oil (M) consisting of M1 = red palm oil (RPO) and M2 = palm cooking oil (PO). The second factor is the variation of frying temperature with the deep fat frying method with 4 levels, namely: S1 = without frying (control), S2 = 180 ° C, S3 = 230 ° C and S4 = 280 ° C. Data analysis was carried out descriptively. The results of the study showed that red palm oil has a higher antioxidant content compared to palm oil and cooking oil with the deep fat frying method. Red palm oil has a DPPH percentage of 28.01%, while palm cooking oil has a DPPH percentage of 28.90. The lower the DPPH percentage, the higher the antioxidant content. The antioxidant content of red palm oil and cooking oil with the deep fat frying method differs with increasing frying temperature. Red palm oil experiences a decrease in antioxidant content with increasing frying temperature, while palm cooking oil experiences an increase in antioxidant content with increasing frying temperature.
