Abstract

Fossil energy is part of the needs of people in any country, including Indonesia. The need for fossil energy is increasing day by day. Therefore, efforts were made to find alternative raw materials from the non-food sector for the manufacture of ethanol. Cellulose material has potential as an alternative raw material for the manufacture of ethanol. One of the wastes that can be used is Arabica coffee skin. This study aims to determine the effect of the concentration of crude cellulase enzyme on sugar and ethanol content of fermented Arabica coffee husk using Zymomonas mobilis and to determine the concentration of crude cellulase enzyme which produces the highest sugar and ethanol content of fermented Arabica coffee husk using Zymomonas mobilis. This research is an experimental study with the independent variables, namely the concentration of crude cellulase enzymes, namely 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, and 17.5% (V/V), and the dependent variable is the sugar content of hydrolysis with crude cellulase enzyme and the ethanol content of fermented with Zymomonas mobilis. The results of the experimental research were analyzed using regression test, ANOVA, and Duncan's test. The addition of crude cellulase enzyme Bacillus subtilis influence the increase in sugar and bioethanol content of fermented Arabica coffee husks using Zymomonas mobilis. The highest sugar content in the P6 treatment (concentration of crude cellulase enzyme Bacillus subtilis 15%) was 0.93 g/mL. The highest levels of bioethanol in treatment P4 (crude cellulase enzyme Bacillus subtilis concentration 10%) was 4.46%.

Abstract

One of the effects of plant fertility is the addition of compost which contains bioactivators. One of the bioactivators that can be used in the composting process is to use MOL (Local Microorganisms). MOL can be made from various types of organik waste that is around us, such as MOL from Banana Stem, Used/Stale Rice, Used/Rotten Fruits, and can also use EM4 purchased at a farm shop. The different types of MOL materials added to the composting will also affect the quality of the compost produced based on SNI 19-7030-2004. Therefore, it is necessary to test the quality of the compost with the addition of different MOLs. This research is experimental research with a qualitative approach. This research was conducted in the Workshop and STTL Mataram Biology and Chemistry Laboratory. The results showed that the four composts that have been researched, there are several parameters that are still not in accordance with the Good Compost Quality Standards based on SNI 19-7030-2004, included the color parameters in the compost with the addition of MOL. there are leaf pieces that have not been completely decomposed, the chemical parameter of COrganik in the compost with the addition of MOL of used rice that exceeds the maximum level of 32.74%, and the level of C/N-Ratio in the compost with the addition of MOL banana stem which is still below the minimum level of 22,7% only. Compost that has good quality and according with SNI 19-7030-2004 is compost with the addition of MOL from EM4.

Abstract

Fermentation technology is one of the subjects in the Food Quality Assurance Supervisor Study Program (SJMP), Vocational School, Bogor Agricultural University (IPB) which is given to semester IV students. Prior to the 2021/2022 academic year, practicum activities were carried out using the teacher centered method using practicum instructions in the form of modules prepared by lecturers, students only followed the modules and were not involved in practicum planning and designing experiments. Through this method, students are not given the opportunity to learn to think critically, creatively, and innovate. One way to optimize the achievement of learning outcomes is to apply the Project Based Learning (PjBL) model. The research was carried out using a one-shot case study method and a descriptive approach to 111 students of the Food Quality Assurance Supervisor Study Program in semester IV. The application of Project Based Learning in the fermentation technology course produces innovative products as project outputs, namely cinnamon yoghurt salad, cowpea tempeh nuggets, red gingerbread, sundubu jjigae with radish-based kimchi, steamed cakes of red dragon glutinous rice tape, braid donuts with fruit glaze Dragon, Dimsum Tempe Bogor Beans, and Frozen Sweet Corn Green Bean Yogurt. Of the 8 products, the panelists liked the red dragon skin glutinous tape steamed sponge cake the most (7.50), so it has the potential to be developed further, while the least preferred product was dimsum tempeh Bogor kacang (4.93). Based on the results of the questionnaire, 100% of students felt that Project Based Learning was effectively applied to fermentation technology courses, could increase motivation and interest in learning, and made it easier for students to understand the material. In addition, 99% of students feel optimistic about achieving competence in the field of food quality assurance, especially controlling fermented food production according to established competency standards, improving design skills and soft skills including teamwork, problem solving, and analytical skills.

Abstract

Mangroves are one of the coastal vegetations that have ecological roles and benefits as disaster mitigation, one of which is the bioaccumulation of lead (Pb) heavy metal contamination. The purpose of this study was to determine the uptake ability of the heavy metal lead (Pb) by mangrove leaf and root tissues, and the potential storage capacity of the heavy metal lead (Pb) in the substrate of the mangrove ecosystem found under stands of each type of mangrove in the Rhizophoraceae family. The research was conducted on the mangrove ecosystem of the Lembar Bay of West Lombok Regency. This research is a quantitative descriptive research using purposive random sampling method, which starts with taking samples of leaves and roots of each different species and taking samples of the substrate found under stands of mangrove species in the Rhizophoraceae family. Sample testing was carried out using the Atomic Absorption Spectrophotometer (AAS) method. The results showed that the heavy metal (Pb) content in the root tissue was greater than the test results on the leaf samples, namely the roots of Bruguiera gymnorrhiza of 7.23 ppm, the roots of Rhizophora stylosa of 2.84 ppm, and the roots of Ceriops decandra. of 2.84 ppm, while for Rhizophora stylosa leaves it was 4.23 ppm, for Bruguiera gymnorrhiza leaves it was 2.92 ppm, and for Ceriops decandra leaves it was 2.91 ppm. In addition, the content of heavy metal deposits found under the Bruguiera gymnorrhiza mangrove stands was 19.64 ppm, rhizophora stylosa substrate was 16.94 ppm, and 12.94 ppm ceriops decandra substrate. Meanwhile, based on the phytoremediation ability of mangrove species in the Rhizophoraceae family of the Sheet Bay mangrove ecosystem, it was found that the leaves of the type Rhizophora stylosa (- 1.24), were higher than those of Bruguiera gymnorrhiza (- 0.26), and Ceriops decandra (0.20). Similarly, the ability of root tissue as a phytoremediation agent was found to be greatest in Rhizophora stylosa (- 1.32).

Abstract

Data on the development of the Covid-19 pandemic as of May 17 2020 shows that all areas in West Nusa Tenggara Province are declared as red zones. This condition causes people to become anxious. One community group that feels this anxiety is beef cattle breeders on smallholder farms. The purpose of this study was to determine the impact of the Covid-19 pandemic on the anxiety level of beef cattle farming families on smallholder farms in West Nusa Tenggara Province. The research method is a survey method from May to September 2022 in 10 regencies/cities throughout West Nusa Tenggara Province. There are 20 parameters that are measured as indicators of anxiety levels. Anxiety levels are measured with a Likert scale of 1-5. Data was tabulated using Microsoft Excel and then analyzed descriptively. The results showed that the impact of the Covid-19 pandemic was most felt by the farmers' wives with an average anxiety level of 97.4%; farmer's children 94.0%; and father as the head of the family 93.3%. The performance of beef cattle breeders is measured by seven indicators showing that 81.5% of beef cattle raising families do not stay at home all day long, but 70.4% leave the house to work in the fields, gardens and fields, and earn a living for their families. The conclusion is that all members of the beef cattle farmer's family feel anxious about the Covid-19 pandemic. The farmer's wife is the member of the family who feels the most anxiety. Nonetheless, the Covid-19 pandemic did not have a negative impact on the performance of beef cattle farming families on smallholder farms in West Nusa Tenggara Province.
