Abstract

Coconut oil is a basic human need. Coconut oil can be made both traditional and enzymatically. Enzymatic manufacture of coconut oil is the separation of oil in coconut milk using protein-breaking enzymes called proteolytic enzymes. Enzymatic production of coconut oil has the advantages of easy-to-obtain raw materials, does not require much energy, and simple processing. This study was conducted to determine the effect of time and amount of papaya juice used with the coconut oil yields obtained. The results of the study at a time of 3 days with a volume of 75 ml of papaya juice, it was obtained that the volume of coconut oil was the most, which was 11.4 ml. Making coconut oil using coconut milk and papaya juice mixed and added 2 grams of tempeh yeast then measured the pH to pH 4. Next, the glass is closed so that air does not enter during the fermentation time of 3-5 days. After being fermented then separated between water and pulp from making coconut oil. Next, pulp from making coconut oil is heated to produce oil. In addition, the free fatty acid test and the saponification number test were also carried out to determine whether the coconut oil produced complies with the quality requirements of SNI 2902-2011. This indicates that some treatment effect of coconut oil compiles is possible, a quality requirement of  SNI 2902-2011.

Abstract

LNG is an alternative fuel to replace diesel and gasoline. The use of LNG as a fuel has many advantages from various aspects. Besides having advantages, LNG also has disadvantages because it contains dangers in it. LNG is a volatile material that is easily flammable, which causes fires and explosions. Environmental Risk Assessment (ERA) is a systematic method used to measure the magnitude of the risk of a process and product that is a hazard to human health and ecology. By conducting an ERA, the risks and hazards of LNG are known. In carrying out the research, describing the LNG delivery system, identifying hazards in the event of LNG released from the carrier, making accident scenarios along with the outcome events that will occur, collecting data, calculating the frequency of accidents and their consequences, determining existing risks, and providing preventive actions, and mitigation. Hazard evaluation was determined using fault tree analysis (FTA) and event tree analysis (ETA). Based on identifying hazards to the storage and transportation of LNG, it is classified into category four and server (severe). Scenarios of releasing LNG into the environment in the process of transporting and storing LNG can be caused by several things, including external factors, failure in filling, and failure due to excess pressure so that it can cause fire pools/BLEVE events, cloud vapor explosions, flash fires, and cloud vapors. Based on the level of risk entered into, not tolerable action at the next opportunity.

Abstract

The outbreak of the Covid-19 Pandemic that spread throughout the world caused by sars virus infection has resulted in people being wary of viral or microbial spreading. In addition, there is relationship of environmental conditions and the survival and the transmission of microbes. Especially in various environmental problems caused by microbial pollution. Empowering community knowledge of the relationship between microbes and the environment is needed to build an insightful and wise society to respond to The existence and the spreading of microbial in the environment. The method used in this activity is knowledge sharing by organizing webinar consisting of three stages, namely pretest, online education using google meet and postest using google form. Data processing by excel calculations, the results of increasing knowledge after the knowledge sharing were obtained, namely 90.81% comparing with before knowledge sharing namely 87.75%, although overall there is an increase in public knowledge. Thus, knowledge sharing or knowledge counseling can be said to be effective for increasing public knowledge.

Abstract

Black Soldier Fly or Hermetia Illucens (BSF) is known for its potential as a biological agent that helps in the process of natural conversion of organic waste. Resulting compost and a large number of BSF colonies, potentially to be use as a non-food raw material in bioenergy production. The Method is BSF conversion experiment by direct transesterification reaction using Lab-scale bioreactor in 100ml three bottle neck flasks, the solution mixture consists of BSF powder, immobilized whole cell biocatalyst, and solvent. The Result is although in appearance the structure of the test mixture solution did not show an oily character, but based on the viscosity and density test, the test solution had density value 0.81 g/cm3 and viscosity value 1,024 mm2 /s which are above the value of the viscosity and density of methanol but still below the value of the viscosity and density of both SNI and EN14214 biodiesel standard, this could be due to insufficient separation or reaction, imperfect condition, and impurities that are still present in biodiesel products. It can be concluded that a transesterification reaction has occurred in this trial, however further analysis and more experiments are required to definitely conclude the changes in biodiesel production.

Abstract

Plant host symbiosis is close related to soil microbial abundance. Soil microbial abundance will affect soil quality and fertility, thus will improve plant growth. Studies on soil microbial abundance in succulent plant rhizosphere, especially in Indonesia, are scarce. This study aims to observe soil microorganisms' existence and their abundance on succulent plant rhizosphere. This research used two primary methods to isolate Arbuscule Mycorrhizal Fungi (AMF) and actinomycetes. The spore extraction (soil separating) method was used to obtain AMF spores, followed by the root staining method to observe AMF infection on the plant roots. Serial dilution and pour plate method were used for isolation of Actinomycetes. The isolation results showed a high number of Actinomycetes distribution up to 3.3 x 106 Actinomycetes CFU/g from the plant Echinocactus grusonii, while AMF spores displayed the most elevated number up to 47 spore/25g from the plant Deuterocohnia sp. The percentage of AMF root infection is covered by 27,9% median. AMF identification was based on spore. The result showed an abundance presentation of Actinomycetes in each soil sample. AMF and Actinomycetes existence displayed symbiotic interaction between succulent plants and soil microorganisms. AMF and actinomycetes play the role of endophytes that help the growth of cacti, generally have a dry growing environment, and limited nutrition by this symbiotic interaction. Actinomycetes distribution in rhizospheric soil will increase plant growth-promoting factors activity. Eventually, the implications of research results are to explore the abundance and biodiversity of soil microorganisms from succulent plant rhizosphere that lacked exploration.
