Abstract

Nagari Sikucua, Kampung Dalam Subdistrict, Padang Pariaman produces nearly 800 tons of fragrant areca nut every year which is sent to Jambi to meet export needs. Areca nut contains tannins, substances that have many benefits, some of which are anti-inflammatory, corrosion inhibitors, antioxidants. This study aims to obtain tannins in areca nut extract through a kinetic maceration process with pre-treatment with ultrasonic irradiation wave. The dried areca nut was ground and sieved with various sizes of 20, 40 and 70 mesh and then extracted with ethanol as solvent. The concentration of ethanol used consisted of 35%, 50%, 65% and 80%. Ultrasonic irradiation waves were given for the initial 15 minutes of maceration and then continued with kinetic maceration for up to 4 hours in a water bath at 45°C. The extraction results were concentrated in a rotary evaporator and then tested for tannin levels using Follin Denish reagent in the standard series of tannic acid as a comparison with spectrophotometer UV-Vis. The highest yield of tannin content 11.10% was obtained in the 4-hour maceration process with pre-treatment ultrasonic irradiation at concentration of 80% ethanol with a size of 40 mesh.

Abstract

Aromatic areca catechu is one of the main agro commodities in West Sumatra. It contains tannin which are valuable compounds that are widely used in the textile industries, leather product manufacturing, or furniture industries. Utilization of tannin extraction from the aromatic betel nut is expected to increase its economic value. This study aims to extract tannin through kinetic maceration methods by varying the maceration duration of 1,2,3,4, and 5 hours; and varying the solvent concentration of ethanol 35%, 50%, 65%, 80%, and 96%. The scented areca nut powder used has a mesh size of e” 20, the stirring speed 450 rpm and the temperature kept constant at 45 oC. The extraction results were then concentrated and tested by UV-Vis spectrophotometric analysis with a standard solution of tannic acid. Optimal yield value is 3.750%  identified at maceration length of 2 hours with a solvent concentration of 65% ethanol.

Abstract

Natural gas is one of the primary hydrocarbon energies in Indonesia. The construction of natural gas production facilities is essential to accommodate domestic energy needs. These facilities include production, pipelines, and processing facilities in an integrated manner. This study used the hydrocarbon composition of Field-X with an average of 7.62% CO2 and 0.06% H2S. The alternative design uses a fixed platform (fixed platform), MOPU (Mobile Offshore Production Unit), and a Semi-Submersible platform. The design comparison criteria are capital expenditure (CapEx), net present value (NPV), internal rate of return (IRR), work completion time, safety risk, and flexibility of future facility development. Through the comparison method, it is found that Option A is the best option, which has a design criterion value of 57%, a higher NPV of $43,537,469.58 than the smallest NPV option, an IRR of 19%, and a payout time (POT) of 5 years. Option A uses a fixed platform with a pipeline to the north, the hydrocarbon separation process is carried out on an offshore platform, and the processing is carried out onshore. ABSTRAKGas alam merupakan salah satu energi hidrokarbon utama di Indonesia. Pembangunan fasilitas produksinya sangat penting untuk mengakomodasi kebutuhan energi dalam negeri. Fasilitas ini meliputi produksi, jalur pemipaan, dan fasilitas pengolahan hidrokarbon secara terintegrasi. Penelitian ini menggunakan komposisi hidrokarbon dari Lapangan-X dengan rata-rata CO2 7.62% dan H2S 0.06%. Alternatif desain menggunakan anjungan tetap (fix platform), MOPU (Mobile Offshore Production Unit), dan anjungan Semi-Submersible. Kriteria perbandingan desain adalah modal awal, nilai bersih saat ini (NPV), tingkat pengembalian internal (IRR), waktu penyelesaian pekerjaan, resiko keselamatan, dan flexibilitas pengembangan fasilitas kedepan. Melalui metode perbandingan yang dipadankan didapatkan Opsi A  adalah opsi terbaik, yang memiliki nilai kriteria desain 57%, NPV lebih tinggi $43,537,469.58 dibanding opsi NPV terkecil, IRR 19% dan waktu pembayaran (payout time/POT) 5 tahun. Opsi A  menggunakan anjungan tetap dengan jalur pemipaan ke arah Utara, proses separasi hidrokarbon dilakukan pada anjungan lepas pantai (offshore) dan pengolahannya dilakukan di darat (onshore).

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.
