Abstract

Non-edible oils are not used as food, which comes from plants that are not used properly, but are very abundant and even become waste. These plants are able to produce high enough oil, which is around 30-80% with a composition that is almost similar to edible. The oil can be obtained by extraction. However, most people do not know how to extract these oils. Therefore, it is necessary to introduce and train on how to extract these non-edible oils, especially people who have the potential to be young entrepreneurs, one of which is SMK. SMKPP Negeri Mataram is one of the secondary schools that carries out the mission of education in the field of agriculture extensively and prepares capable and skilled human resources in agriculture. This service aims to increase the knowledge and understanding of SMKPP Negeri Mataram students about local plants that have the potential as non-edible and oil extraction training which can later become the provision of students after graduation by taking advantage of the potential and opportunities that exist around them. This service activity will be carried out in two stages, namely introduction/socialization activities about plants that have the potential as non-edible and simple oil extraction training. The results of service activities have provided additional knowledge and understanding of SMKPP Negeri Mataram students about local plants that have the potential to produce non-edible oil and simple oil extraction techniques.

Abstract

This paper aims to characterize and test the stability of sulfuric natural water (SNW) from Sebau East Lombok as a sulfidation agent for several dissolved metals (Mn, Cu, Pb and Fe). The parameters used for SNW characterization are temperature, pH, DO, BOD, COD, TSS, and TDS. The sample was divided into two categories, namely the sample with preservation treatment and the sample without preservation, to study the stability of SNW. The SNW stability was determined by observing the SNW parameters in both samples at a storage time of 5, 10, 15 and 20 days and reacting them with dissolved metals. The SNW with preservation had reduced sulphide levels from day 1 to day 20, ranging from 59.24 mg/L to 17.70 mg/L, whereas the sample without preservation had decreased sulphide concentration from 52.46 mg/L to 9.56 mg/L. Furthermore, the SNW with preservation has a relatively superior metal reduction ratio than the sample without preservation. The maximum value of the deposition ratio for Mn metal was obtained on the fifth day with 57.60%, 83.45% for Cu, and 91.87% for Pb. This trend is not applicable for Fe, whereas the highest reduction (87.23%) was obtained on the the15th day's storage.

Abstract

This study aims to determine the formulation and antibacterial effectiveness of fermented soybean seed husk extract from tempe industrial waste as an environmentally friendly hand sanitizer gel. This type of research is an experimental study with variations in fermented soybean husk extract concentration, namely 0%, 5%, 15%, 20%, 50%, and 100%. Observational data were tested by analysis of variance ANOVA at a 5% level using Co-Stat software. Suppose there is a significant difference, a further test of Honest Significant Difference (BNJ) (organoleptic test), a further test of Orthogonal Polynomial Method (MOP) (spreadability, pH, viscosity), descriptive analysis test (flavonoid test, homogeneity test, antibacterial activity test is carried out) and test the total number of germs). The results showed that the fermented extract of soybean seed husk was positive for flavonoids, characterized by a bright yellow color change when added with 10% NaOH. The concentration of fermented soybean husk extract significantly affected the hand sanitizer gel's organoleptic properties, dispersion, total pH, and viscosity. Based on the organoleptic test, the panelists preferred the clear gel color in the F1 treatment (0%) and the thick, slightly liquid gel form with a slightly scented soybean husk in the F3 treatment (10%). The concentration treatment of soybean husk fermented extract (50%) was the best treatment based on good homogeneity, total pH 4.35, viscosity 2405 cPs, following SNI No.06-2588, and spreadability of 4.47 cm which was close to hand gel. For commercial sanitizers, the diameter of the inhibition zone against Escherichia coli bacteria ATCC 2922 and Staphylococcus aureus ATCC 2923 is 14 mm and 12 mm.

Abstract

Mercury is a dangerous and toxic metal, thus necessitating an analytical method to ascertain its presence. Traditional methods for mercury analysis often involve costly instruments and specialized expertise. However, the Digital Image Colorimetry (DIC) method is an alternative for mercury detection due to its speed, simplicity, and cost-effectiveness. This research aims to synthesize silver nanoparticles (AgNPs) using Kepundung fruit peel (Baccaurea racemosa) extract as a mercury detector. Baccaurea racemosa has secondary metabolite compounds that can act as natural reducing agents (bioreductors) in synthesizing silver into nanoparticles. AgNPs were optimized and characterized using UV-Vis spectrophotometer, FTIR, PSA, and XRD instruments. Mercury detection was explained using RGB Detector and ImageJ. The research results revealed that the optimal conditions for synthesizing AgNPs involved a concentration of 1% extract and a pH of 7. The properties of the AgNPs included a maximum absorption at wavelengths of 400-450 nm, an average particle size of 122.7 nm, a face-centered cubic crystal structure, and characteristic functional groups at wavenumbers of 3453 cm-1, 1700-1600 cm-1, and 1445 cm-1. These spectral features suggested the presence of phytochemical compounds serving as bioreductants. Optimal results for mercury detection were achieved using Whatman paper no. 41 at pH 7. Mercury was detected successfully, whereas Pb2+, Na+, Mg2+, K+, Cu2+, Ca2+, Co2+, Zn2+, and Fe3+ ions were not detected. The validation test obtained a LoD of 0.099 ppm, a LoQ of 0.330 ppm, and a coefficient value (R2) of 0.997, indicating good measurement linearity. Further research can be developed to increase the sensitivity of mercury detection with lower concentrations and extend its application to environmental samples.

Abstract

Epoxy is a cyclic ether compound that contains an oxirane group and has been widely applied as a stabilizer, plasticizer in polyvinyl chloride (PVC), surfactant, pesticide raw material, and as a polymer resin coating. The raw materials in epoxy synthesis come from petroleum derivatives, which are non-renewable natural resources. Therefore, there is a need for alternative raw materials that can be renewed, such as vegetable oil. In this study, nyamplung seed oil was used. Epoxy synthesis is usually carried out using carboxylic acid epoxidation with the help of an acid catalyst. This research aims to determine the effect of the type of acid catalyst and its concentration on the epoxidation reaction of nyamplung seed oil and the characterization of the epoxy produced. The research results show that using an acid catalyst can increase the formation of oxirane groups at a certain concentration, where the highest oxirane number value was obtained when using the H2SO4 catalyst, namely 3.15%. The resulting epoxy is pale yellow, has a typical absorption area (COC) at a wave number of 825 cm-1, an iodine value of 13.96 g iod/100 g, a viscosity of 20.80 cP, and a relative per cent conversion to oxirane of 73.4 %

Abstract

Moringa seed oil is a vegetable oil that has many benefits for health and the pharmaceutical industry. Moringa seed oil can be extracted either chemically or mechanically. This research aims to characterize moringa seed oil’s physicochemical properties and fatty acid composition using soxhletation chemical extraction and screw-pressing mechanical extraction with various pretreatment temperatures of 50, 60, and 70°C. The research showed that the highest yield of moringa seed oil, 41.74%, was obtained at an initial treatment temperature of 70°C using the soxhletation method for 6 hours. The acid value of moringa seed oil from soxhletation is 2.01 mg KOH/g, and screw pressing is 4.37 mg KOH/g. The iodine number from soxhletation was 66.62 mg iod/100g, and screw pressing was 60.27 mg iod/100g. The density of the oil from soxhletation and screw pressing is 0.922 mg/mL and 0.934 mg/mL, respectively, with an oil viscosity of 3.298 cP and 3.424 cP. The results of GC-MS analysis show that moringa seed oil from soxhletation has an oleic acid composition of 40.92%, while the screw pressing has an oleic acid composition of 22.50%. This finding demonstrates the influence of extraction methods on the fatty acid profile, particularly the concentration of oleic acid, a key component of moringa seed oil. These results contribute to understanding how specific extraction techniques can optimize the quality of moringa seed oil.
