Abstract

Fatty acid methyl ester (FAME) merupakan bahan bakar alternatif pada mesin diesel yang terbarukan. Penelitian ini mensintesis FAME melalui transesterifikasi minyak biji mahoni dengan metanol menggunakan katalis KOH. Tujuannya (1) mendapatkan kondisi optimal sintesis FAME, (2) mengetahui sifat fisis FAME, dan (3) mengetahui performancenya. Minyak biji mahoni memiliki bilangan asam yang tinggi (29,86 mg KOH/ g minyak) sehingga dilakukan esterifikasi. Esterifikasi dilakukan pada suhu 35°C menggunakan katalis H . Transesterifikasi dilakukan dengan perbandingan minyak: metanol= 4:1. Variasinya suhu (30°C - 60°C) dan konsentrasi KOH (0,5% - 1% berat minyak). Didapatkan kondisi optimum reaksi transesterifikasi pada suhu 60°C, konsentrasi KOH 0,75%, waktu reaksi 60 menit, serta rasio volume minyak:metanol= 4:1, dan didapatkan yield sebesar 83,9742%. FAME diuji sifat fisisnya dengan variasi perbandingan FAME:solar: butanol sebesar 1:0:0, 1:1:1, dan 1:2:2. Pengujian meliputi densitas, korosi lempeng tembaga, color ASTM, viskositas kinematis, flash point, pour point, kandungan air, serta CCR. Hasilnya dibandingkan dengan standar kualitas biodiesel (SNI). Data menunjukkan bahwa semua komposisi campuran FAME:solar belum memenuhi persyaratan standar. Uji performance secara lengkap belum dapat dilaksanakan karena dapat menyebabkan kerusakan mesin, tetapi performance konsumsi FAME pada mesin diesel tidak jauh berbeda dengan konsumsi solar pada mesin diesel, tetapi emisinya lebih rendah.

Abstract

The rapid growth of the population and economy has boosted up the necessity of fuel and  energy source. Until now, the world’s dependency on fossil fuel as the primary energy supply is still high. On the other hand, it has been known that the fossil-based oil and gas reserves are shrunk. Hence, it is urgent to develop alternative energy sources, which are renewable and environmentally friendly, to anticipate the energy insufficiency. Biodiesel is among the prospective renewable energy due to its advantages. Biodiesel (fatty acid methyl esters) is a type of biofuel which is derived from vegetable oil or animal fat. There are various vegetable oils that can be used as raw material for biodiesel production. However, non-edible oils are usually preferred to be selected as a biodiesel feedstock to evade the conflict between food and energy needs. Kapok Randu (Ceiba pentandra) seed oil is a type of non-edible oil which is cheap and can be employed as biodiesel feedstock. However, this oil has high free fatty acid (FFA) content (8.89%). Thus, it cannot directly undergo transesterification reaction to produce biodiesel since the FFA will react with alkaline catalyst to produce soap. The FFA content in Kapok Randu seed oil needs to be decreased until it is lower than 2%. Hence, prior to transesterification reaction, esterification of Kapok Randu seed oil with methanol in the presence of acid catalyst should be conducted to decrease the FFA content. In this work, esterification reaction was performed in the presence of sulfuric acid catalyst. The reactions were conducted at the molar ratio of oil to methanol of 1:12 at the temperature of 40, 50, and 60 ℃ for 120 minutes. The optimum reaction conversion was 95.14%, achieved at the reaction temperature of 60 ℃. Kinetics study using homogeneous models was also performed. It was revealed that the reaction was appropriate with the irreversible second order reaction model. The reaction rate constant (k), activation energy (Ea), and  frequency factor (A) were 4.95 L / mole.min, 30,799.21 J/ mole and 338.744 / min, respectively.

Abstract

Biodiesel is one of the promising energy source alternatives to fossil fuel. To produce biodiesel in a more economical way, the employment of the low-cost feed stocks, such as non-edible oils with high free fatty acid (FFA), is necessary. Accordingly, the esterification reaction of FFA in vegetable oils plays an important role in the biodiesel production. In this work, esterification of FFA contained in Crude Jatropha Oil (CJO) in the presence of tin (II) chloride catalyst in a batch reactor has been carried out. The esterification reaction was conducted using methanol at the temperature of 40-60 °C for 4 hours. The effect of molar ratio of methanol to oil was studied in the range 15:1 to 120:1. The influence of catalyst loading was investigated in the range of 2.5 to 15% w/w oil. The optimum reaction conversion was obtained at 60 °C with the catalyst loading of 10% w/w oil and molar ratio of methanol to oil of 120:1. A pseudo-homogeneous reversible second order kinetic model for describing the esterification of FFA contained in CJO with methanol over tin (II) chloride catalyst was developed based on the experimental data. The kinetic model can fit the data very well.

Abstract

Tofu is famous as a favorite, healthy, nutritious and cheap food in Indonesia. The tofu industry has been growing rapidly in this country in the form of household scale businesses or MSME (Micro, Small and Medium Enterprises). Among the tofu MSME centers in Semarang is the one in Sumurrejo Village, Gunungpati District. Sumurrejo village has various business potentials that are capable of driving the community’s economy, especially the entrepreneurship of tofu and tempeh MSMEs, as well as dairy and beef cattle farming. The MSMEs in this area are growing rapidly and able to improve the economy of the local community. In spite of this positive impact, the existence of tofu industry also has a negative effect since its waste causes environmental pollution problems. One of them is tofu dreg waste which can cause pollution to the environment due to its bad smell, organic matters content, and putrefaction potential. One effort to overcome this problem is to process the tofu dreg waste into animal feed. Tofu waste has high nutritions which consist of 8.66% protein, 3.79% fat, 51.63% water and 1.21% ash. Therefore, in order to resolve the environmental problems caused by the disposal of tofu waste and the problem of the high price of commercial animal feed, it is necessary to conduct community service activities to increase the added value of tofu waste by processing it into animal feed through fermentation process. Tofu pulp fodder produced in this activity was also tested on chickens. Chickens that were feed with tofu waste shown a better weight gain than those given regular fodder (pur). Training on tofu waste processing into fodder was very useful for the community within the area of the tofu industry in Sumurrejo Village because it could overcome the environmental problems caused by tofu dreg waste and could provide cheap, nutritious, safe animal feed and support the livestock growth. Community service activities were conducted by providing knowledge and skills through lecturing, practice and skills training, as well as monitoring activities.

Abstract

Durian (Durio zibethinus Murray) is a tropical, delicious and expensive fruit with specific aroma. Indonesia is among the biggest and the best durian fruit producer in the world. There are various types of Durian in Indonesia, coming from different areas. Based on the data released by the Central Bureau of Statistic, it was demonstrated that the main provinces producing durian in 2019 were East Java, Central Java, West Java, North Sumatera, West Sumatera, Banten, South Sulawesi, and South Sumatera with the total harvest of  289,334 ton, 172,939 ton,  94,183 ton, 90,105 ton, 62,564 ton, 46,436 ton, 45,729 ton, and 42,048 ton, respectively. The high production of durian fruit is beneficial for the agroindustrial and economic sectors. On the other hand, it also results in the abundance waste during the harvest time which causes many problems to the environment. The percentage of durian flesh of fruit is only 20.52%, meaning that the 79.48% of durian is unutilized parts such as shell and seeds. The waste resulted from durian is about 556,360 ton per year. Durian waste, especially durian shell, is difficult to degrade. Hence, the proper waste management of the durian shell is crucial. The strategic way to manage the durian shell is by upgrading this waste into various valuable products. In this work, the innovation of the durian shell waste conversion into diverse product to support the national food security during the covid-19 new normal era is discussed.  Durian shell is potential to be used for the production of food products such as candy, pectin, edible film, and crackers, flour, and noodle. It also has potency to be utilized in the production of products which support the development of food crop agriculture and animal husbandry, such as biopesticides, organic fertilizer, and animal feed, which strongly associated with the food supply security.

Abstract

Tofu is a food that people are fond of and is recognized as healthy, nutritious and cheap cuisine. The tofu industry has been growing rapidly in Indonesia in the form of household scale businesses or MSME (Micro, Small and Medium Enterprises). On the other hand, tofu industry also has a negative impact to the environment due to its waste. The waste of tofu industry has high level of BOD and COD so that it becomes organic pollutant for groundwater and creates an unpleasant odor. Tofu components that potentially become liquid waste are the organic compounds such as protein (40-60)%, carbohydrates (25-50)%, and 10% fat. The largest component of tofu liquid waste is protein, which is 226.06 mg/L to 434.78 mg/L. This nutrient content allows tofu liquid waste to be processed into liquid organic fertilizer through a simple fermentation process. In this community service project, short training on processing tofu industrial liquid waste into liquid organic fertilizer has been conducted in Sumurrejo are, Semarang. To utilize this organic fertilizer for plant growing, an alley garden was also established in the village.

Abstract

Controlling the release rate of the nitrogen-phosphorus-potassium (NPK) for the soil fertilized can enhance the fertilizer efficiency and reduce the drawback for the environmental. In this work, a novel slow-release organo-mineral fertilizer was produced from the vinasse, which was blended with the NPK and the chitosan-bentonite matrix. The NPK used as additional nutrients source and the chitosan-bentonite matrix was performed as a barrier to prevent the nitrogen, phosphorus, and potassium from a rapid dissolving. The NPK release rate was measured and analyzed after 3, 6, 9, and 12 days using the incubation method and leaching test. The most efficient release rate was obtained when a dry vinasse mixed with 9% NPK and 5% chitosan-bentonite matrix with the ratio of 8:2. The vinasse-based slow-release of organo-mineral fertilizer (SR-OMF) was compared to the vinasse organo-mineral fertilizer (OMF). The result indicated that the NPK release rate in the vinasse-based SR-OMF was lower compared to that in the vinasse OMF.
