Abstract

Agarwood is one of the forest products that can be utilized and has a high selling value. Agarwood contains essential oils which have many active compounds and contains a specific aromatic resin that is naturally formed as a form of defense against physical damage or microbial infection. Agarwood essential oil with good quality has a high economic value. This study aims to extract agarwood essential oil using ethanol as a solvent. The optimal yield of agarwood essential oil can be obtained by varying the particle size, the ratio of the weight of the agarwood biomass (kg) to the volume of the solvent (L), and the length of maceration (h). The results showed that the particle size of agarwood did notaffect the yield of agarwood essential oil. The results of the comparison of agarwood biomass with the volume of the solvent showed that the ratio of 1:9 (w/v) obtained the highest yield of 4.02% and the longest maceration time with the highest yield of 4.12% for 72 hours. However, 48 hours of maceration had a greater increase in yield compared to 72 hours of maceration. The increase in yield at 48 hours to 72 hours of maceration was only 0.22% when compared to the increase in yield at 24 hours to 48 hours of maceration, which was 0.56%.

Abstract

Oil palm empty fruit bunch (EFB) is one of the biomass wastes that have a great potential of a bioenergy resource due to its natural properties, such as high calorific value. The conversion of EFB biomass into valuable biofuels can achieved through biochemical and thermochemical processes. Tar (bio-oil), the liquid product from the pyrolysis is one of the most attractive biofuels. The study aims to determine the effect of temperature process of pyrolysis EFB on its tar production under droptube reactor. The results showed that maximum tar yield was 43,80% obtained at 500 °C. The EFB tar produced at 500 °C was also determined to have a higher of phenol compound at 51,9%. The high phenolic content indicates its potential to be used for the production of renewable phenolic resins. Hence, the present work of pyrolysis of EFB presents itself as a promising method to produce phenol rich tar (bio-oil) from biomass waste.

Abstract

The agricultural sector is one of the main pillars of the economy in Koto Tangah District. Increasing agricultural production requires the support of fertilizer availability in terms of quantity and price. In order to provide fertilizer at competitive prices, fertilizers are needed at low prices and are environmentally friendly. This community service activity is given to the community in Lubuk Minturun Village in the form of training in the manufacture of liquid organic fertilizer (POC) with a fermentation process and extracts of lemongrass. The main ingredient of this fertilizer is rice waste which can be easily collected by local people. The training covers the process of making fertilizer, the fermentation process to packaging. Lemongrass extract is added to increase nutrients in the soil and reduce odors from the fermentation process. The proposing team took this theme in order to provide an alternative for making POCs to the community in Lubuk Minturun Village in the hope of contributing to local flower or fruit plant nurseries. In this case, the proposing team took Lubuk Minturun Village as a model because this area is located close to the ATI Padang Polytechnic Campus, so that it can help the lives of the people around the campus.

Abstract

West Sumatra has a high potential of coconut resources with most of it being processed for copra products. The pandemic situation in recent years has caused the price of copra products to fluctuate, so an alternative coconut processing is needed. Virgin Coconut Oil (VCO) is an alternative coconut product that can increase economic value of coconut and is needed as a supplement that can strengthen the body's immune system during the Covid-19 pandemic. One of the efforts to train the community to be able to process coconut into VCO is to conduct training activities that are directly located in the coconut farmer cluster, which is carried out in Sungai Sirah Village, South Coast District, West Sumatra. This community service activity aims to increase the competence of farmers in the village so that they can process the coconut produced into VCO, hence help their economy when the price of copra drops. The stages of the activity start from socialization, presentation on production process, and continued with demonstrating how to make VCO. Participants were divided into several small groups where they could immediately practice how to make this VCO with the correct fermentation steps. After the manufacturing process is well understood, the next step was training of how to do packaging and marketing. Farmers were trained on how to package products in order to get good quality product and then trained to sell VCO through online shop such as Facebook, Instagram, Tokopedia, etc. This activity helps add more insight in terms of processing and marketing, in which participants increase their knowledge and competence to form the basis for entrepreneurship of coconut processed products.

Abstract

The complex fertilizer industry produces wastewater which contributes to the pollution of water bodies because it contains high levels of phosphate and ammonium concentrations and high TKN (Total Kjeldahl Nitrogen) which contains organic nitrogen. The organic nitrogen contained in the complex fertilizer wastewater is urea so it can be hydrolyzed to ammonium using the urease enzyme. The ammonium formed from the hydrolysis of urea will then react with magnesium and phosphate to form struvite, a crystal of Magnesium Ammonium Phosphate (MAP). The purpose of this study was to determine the effect of aeration and the enzyme urease in the removal of ammonium and phosphate in complex fertilizer synthetic wastewater through struvite precipitation. Struvite precipitation was carried out in a batch reactor which had a working volume of 0.5 L with variations in aeration rate, aeration time, and the addition of urease enzyme from Jack bean peas (Canavalia ensiformis). Residual ammonium and phosphate levels were analyzed and struvite crystal formation (MAP) was determined using Scanning Electron Microscope (SEM) and X-ray diffraction (XRD). The results showed that the aeration reactor was able to form struvite crystals and remove the ammonium and phosphate content in the synthetic wastewater of complex fertilizers. The removal of ammonium with a molar ratio of [Mg2+] : [NH4+] : [PO43-] 1:2:1 reached 61-77% at high aeration rates because a lot of ammonium was released into the air. The phosphate removal reached 99%. The urease enzyme was proven to be able to hydrolyze urea into ammonium and increase the pH value and affect the shape of the resulting struvite crystals. The precipitate product obtained was struvite crystals which were confirmed by analysis using SEM-EDX and XRD.
