The Refined Bleached Deodorized Palm Oil (RBDPO) is a derived product of crude palm oil that has twofraction (olein and stearin) in ambient temperature. This research aim to analyze the variation of treatmenton the RBDPO. The design of research was non-factorial completely randomized with three variable oftreatment such the RBDPO with glycerol (A), the RBDPO (B) and the RBDPO with lipase enzyme. Theconcentration of glycerol, ester, mono- and diglyceride was tested by Gas Chromatography method. The datawere analyzed by using descriptive method with boxplot and histogram. The result showed that the highestconcentration of glycerol; ester; mono- and diglyceride respectively were showed in treatment B (1,5922%);C (9,5699%); C (0,1783%); C (3,3329). The boxplot graphic described the differences among the treatmentthat the RBDPO with lipase enzyme had the most extensive concentration of glycerol, ester, mono- anddiglyceride.

Palm oil empty fruit bunches (EFB) and fronds are solid waste originating from palm oil processing which can be used as the main raw material for making briquettes. This is supported by its contents, namely lignin, hemicellulose and cellulose. The smaller the particle size, the greater the compressive strength of the briquette, but the burning rate will be slower because the cavity/pores of the briquette are smaller. This research aims to determine the effect of particle (mesh) size on the characteristics of briquettes which include water content, ash content, density, compressive strength and burning rate as well as to determine the best composition of a mixture of empty oil palm fruit bunches and fronds. The results of this research show that the best particle size is 70 mesh briquettes with a raw material composition of 46% EFB and 46% fronds (1:1) with 8% tapioca flour adhesive. Biobriquettes with small particle sizes have lower calorific value. The results of this research indicate that the manufacture of briquettes is in accordance with the Standard Characteristics of SNI No. 1/6235/2000.

Unproductive oil palm stems can produce Umbut which is the raw material for bioethanol production. In general, the production process of bioethanol from lignocellulosic materials includes oil palm stalks. The bioethanol production process goes through several stages of physical, chemical or biological pretreatment, polymer saccharification, sugar fermentation, and ethanol separation and purification. This study aims to determine the production of bioethanol from oil palm stems (Elaeis Guineensis Jacq) through a pretreatment process using H2S04 and fermentation using baker's yeast (Saccharomyces cerevisiae). The method used in this study was a Completely Randomized Design (CRD) Non Factorial with 3 treatment levels and 1 control, and 3 repetitions (Triplo) with a total sample of 12 samples. The resulting bioethanol is then tested (moisture content, yield, and pH). The resulting data were analyzed using ANOVA and Duncan's test. Based on the results of this study, the best treatment was found in the H0 treatment with a yield of 34.5%, 1.52% moisture content and 5,6 % pH

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.

Palm Oil Mill Effluent (POME) is abundantly available in the palm oil industry and has significant potential for generating renewable energy, specifically biogas, through the biogasification process. This study investigates the relationship between the reduction of Chemical Oxygen Demand (COD) values and pH changes in POME during the biogas production process. The study employs a Completely Randomized Design (CRD) with a single factor and four levels. Data were analyzed over five observation periods spanning 24 days. The results show a significant decrease in COD concentration from 96,300 mg/L on day 0 to 22,720 mg/L on day 24. This reduction is attributed to microbial activity, with Effective Microorganisms (EM4) being used in this research. Additionally, an inverse relationship between pH and COD was observed, where an increase in pH correlated with a decrease in COD. Biogas production also increased over time, with the cumulative biogas volume reaching 5.2 liters on day 24. The study concludes that more alkaline environmental conditions support the activity of microorganisms responsible for COD reduction and higher biogas production. Recommendations for future research include adding parameters such as temperature and Volatile Fatty Acids (VFA), and further investigation into more effective and efficient microorganism seeding. Thus, this research provides insights into the biogasification process and the development of more efficient and sustainable biogas technology.

Technological advances have penetrated all of society's lives. Almost every corner and human activity is now accompanied by technology, including religious values. Da'wah, which was previously carried out verbally and held in a private house, has now shifted into a space that is not limited by time. For example, the use of Virtual Reality (VR) and Augmented Reality (AR) technology has been carried out in the medical, military, education, robotics and urban planning and civil science fields. Apart from that, the potential use of Virtual Reality (VR) and Augmented Reality (AR) technology can be used as a da'wah media. So the aim of this research is to analyze the potential of using Virtual Reality (VR) and Augmented Reality (AR) in the world of modern preaching. The approach used uses a literature review. The first formulation of the problem is, what is the potential of using Virtual Reality (VR) and Augmented Reality (AR) in the world of modern da'wah? Second, what are the models of Virtual Reality (VR) and Augmented Reality (AR) in the world of modern preaching? The results obtained in this research are that in developing Islamic da'wah, Augmented Reality (AR) technology can be combined with several forms such as: game cards, Islamic propagation story books, brochures/leaflets/poters, and Islamic history museums. Keywords: Da'wah, Media Transformation, Augmented Reality (AR).
