Abstract

Biogas is a potential renewable energy source to meet energy needs, especially in remote areas that do not have access to electricity. The process of making biogas is carried out through anaerobic fermentation of organic materials such as vegetable waste, livestock manure and agricultural waste. This research aims to design a batch type biodigester that can produce biogas from a mixture of goat manure, chicken manure and vegetable waste. Biodigester is a reactor used to produce biogas. The stirred biodigester aims to mix the substrate evenly in the biodigester and prevent the formation of scum. The biodigester designed has a capacity of 120 liters with a stirring system to increase the efficiency of biogas production. The fermentation process was carried out for 21 days by monitoring parameters such as temperature, pH, Chemical Oxygen Demand (COD), and methane gas concentration (CH4). The results showed that the temperature and pH in the biodigester remained in optimal conditions for the activity of methanogenic microorganisms. The highest CH4 concentration measurement was recorded on day 20 at 60%, which indicates good biogas quality. In addition, the flame test on day 21 produced a blue flame, indicating a high CH4 content. The decrease in CH4 concentration at the end of the study was caused by the exhaustion of organic material. This research contributes to the development of efficient and environmentally friendly biodigester technology to produce biogas as a renewable energy source.

Abstract

Blotong merupakan limbah padat yang berasal dari pabrik gula yang berbentuk lumpur berwarna gelap. Blotong merupakan endapan nira kotor yang ditapis di rotary vacuum filter. Blotong memiliki kandungan senyawa organik yang cukup tinggi seperti C, H dan O. Namun pemanfaatan limbah blotong menjadi produk yang bernilai ekonomi tinggi masih sangat sedikit. Blotong jarang dimanfaatkan sehingga akhirnya tertumpuk di pabrik gula dan dapat menyebabkan pencemaran lingkungan, pengolahan blotong menjadi energi terbarukan dapat menjadi solusi dari permasalahan tersebut. Karena blotong mengandung kandungan senyawa organik yang tinggi, maka dari itu blotong dapat dimanfaatkan sebagai bahan baku pembuatan biogas melalui fermentasi anaerobik. PT Energi Agro Nusantara saat ini mencari bahan baku alternatif yang efektif dalam memproduksi biogas. Tujuan dari penelitian ini adalah untuk mengatahui apakah blotong dapat menghasilkan biogas dengan kandungan metana yang tinggi sehingga dapat dijadikan bahan baku alternatif pembuatan biogas di PT. Energi Agro Nusantara. Penelitian dilakukan dengan membuat digester sederhana dengan ukuran 25 liter yang diisi dengan bahan yang diperlukan untuk fermentasi biogas, fermentasi anaerobik dilakukan selama 10 hari, kemudian gas yang dihasilkan diuku kandungan metana nya. Hasil yang didapatkan menunjukkan bahwa blotong dapat menghasilkan biogas dengan kandungan gas metana yang tinggi sehinga dapat dijadkan bahan baku alternatif dalam pembuatan biogas.

Abstract

This research aims to understand the religious experiences of Sapta Darma adherents through the theoretical perspective of Joachim Wach. Sapta Darma believers are a group of believers who have spiritual views and practices that are 'unique' in Indonesia. In this study, researchers used Joachim Wach's theoretical framework, religious experiences were analyzed through three main components: experience dimensions, expression dimensions, and consequence dimensions. This research uses a qualitative method with a phenomenological approach to explore the religious experiences of Sapta Darma adherents. Data was collected through in-depth interviews with believers and participant observation of their religious rituals and practices. The results of the research show that the religious experience of Sapta Darma Sanggar Sanggar Candi Sapta Rengga, Yogyakarta City includes religious experiences which are often experienced through prostration, digging and special rituals. The expression dimension is seen in the form of prayers, mantras and symbols used in religious practices. Meanwhile, the consequence dimension includes changes in behavior and outlook on life of Sapta Darma adherents. Analysis based on Joachim Wach's theory reveals that the religious experiences of Sapta Darma adherents not only provide meaning and purpose in their lives but also form a strong spiritual identity. This study provides insight into how religious experiences can be articulated and internalized in local cultural contexts.

Abstract

The abundant benefits of essential oils have led to a significant increase in demand, prompting researchers to continuously explore this field to achieve optimal results. Various extraction methods can be employed to obtain essential oils. In this study, researchers used the maceration method with variations in several solvents as comparators. The resulting maceration filtrate was subsequently distilled to obtain pure essential oil, aiming to find an efficient process for essential oil production and identify the most suitable solvent for the production process. The solvents used were Methanol, Ethanol, n-Hexane, and Water. During the maceration method, a sample of 150 g lemongrass was prepared with a size of 1 cm and soaked in 1 L of solvent in a closed container for 24 hours. The filtrate was then distilled to obtain a pure product, which was further characterized using GC-MS. The research findings showed that essential oil was extracted most effectively by ethanol solvent, yielding 23.31 g, and the GC-MS analysis indicated that the lemongrass oil contained 25.75% Geraniol. It was concluded that Geraniol is more soluble in ethanol due to its closer polarity to the compounds within lemongrass oil, resulting in a higher yield compared to extractions using other solvents.

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

Plastic waste is a global environmental issue due to its non-biodegradable nature. One potential solution is the development of eco-friendly bioplastics derived from natural materials. This study aims to develop bioplastics based on sago starch with the addition of microfibrillated cellulose (MFC) from empty palm oil fruit bunches as a reinforcing filler to enhance mechanical properties. Additionally, plasticizers such as glycerol and sorbitol were added to improve the elasticity of the bioplastic. The plasticizer concentrations used were 1, 5, 10, 20, and 30% w/w. Characterization was conducted through mechanical property tests (tensile strength, elastic modulus, and elongation percentage), morphological analysis using SEM, and structural analysis with Fourier Transform Infrared Spectroscopy (FTIR spectroscopy). The results showed that the addition of 5% glycerol produced a tensile strength of 26.39 MPa with an elongation of 1.2%, while 20% sorbitol yielded a tensile strength of 25.35 MPa with an elongation of 6.2%. Based on the Indonesian National Standard (SNI) for plastics, the combination of sago starch and MFC with 20% sorbitol provided the best mechanical properties, with a tensile strength of 25.35 MPa and an elongation percentage of 5.6%. In conclusion, sago starch-based bioplastic with MFC from oil palm empty fruit bunches has the potential to serve as an environmentally friendly alternative to synthetic plastics.
