Candlenut oil is obtained by extracting the oil content in candlenut seeds.

In this study, optimization of candlenut oil extraction was carried out using the factorial experimental design level 23. Using this method, it can be determined that the extraction time is the most influential variable in the candlenut oil extraction process. The results showed that the optimum operating conditions were an extraction time of 185 min, a candlenut seed powder size of 20 mesh, and a ratio of material-solvent ratio of 1:6 g/g, resulting in an oil yield of 43.2%.

The process of extracting nyamplung seed oil chemical process produces a higher yield than mechanical. Extraction was collected using the soxhletation extraction method because the oil can be extracted perfectly and requires little solvent. The FFA content is very high, ranging from 15-30% which causes high oil quality to decrease. The high FFA content is due to the high % water content (23-25%) in nyamplung seeds, which causes a hydrolysis process where triglycerides dissociate in the presence of water, glycerol and FFA. The research variables are the moisture content of nyamplung seeds (8% and 12%), the size of the material (15 and 25 mesh), and the ratio of the material to the solvent (1:4 and 1:6) using the factorial design method for research optimization using variable moisture content Nyamplung seed is 8%, size is 20 mesh, and raw material to solvent ratio is 1:5.

Papaya seeds are a significant component of the fruit, comprising approximately 14.3% of the total fruit weight. These seeds contain about 25% vegetable oil, predominantly composed of unsaturated fatty acids, which have the potential to be processed into consumable oil. The extraction method employed is Soxhlet extraction using a non-polar solvent, n-hexane. A factorial design level 23 was utilized to determine the most influential process variables. The variables were considered to the ratio of papaya seed mass to solvent volume (1:7 and 1:11), particle size (10 and 30 mesh), and extraction time (170 and 190 min). Optimization was conducted using the quicker method calculation, where the determination of the largest effect and the largest main effect played a crucial role. The analysis revealed that the ratio of papaya seed mass to solvent volume had the most significant main effect, with an effect value of 0.1217. From the analysis, it was found that the 1:7 ratio produced the lowest level of Free Fatty Acids (FFA) in the oil, at 0.5076%, which aligns with the Indonesian National Standard (SNI) requirement of 0.36-0.82% FFA content. Furthermore, an analysis of density, viscosity, and moisture content was conducted on the 1:7 ratio. The test results showed that the 1:7 ratio resulted in an oil density of 0.924 g/mL, moisture content of 0.07127%, and FFA content of 0.5076%. However, based on theoretical knowledge, an increase in FFA content leads to a decrease in oil quality. Additionally, higher ratios corresponded to increased moisture content and density. In conclusion, the papaya seed oil produced in this study complies with the Indonesian National Standard (SNI, 01-3555-1998) regarding FFA content (0.36-0.82%), moisture content (maximum 0.15%), and density (0.924-0.929 g/mL).","PeriodicalId":170738,"journal":{"name":"Journal of Vocational Studies on Applied Research","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122499486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the alternatives is to use raw materials such as potential non-rice tubers. In this study, raw material composite flour was made from cassava (Manihot esculenta), gembili (Dioscorea esculenta), koro pedang (Canavalia ensiformis), and corn (Zea mays), which is the basic ingredient of rice maker analog. This research aimed to examine the influence of the raw material composition on the value of nutrients, the physical-chemical properties of analog rice compared to a rice paddy, and the best temperature of analog rice using organoleptic tests. The process of producing analog rice consists of several stages of research, including the manufacturing of composite flour, the cooking of dough with composite flour, the production of analog rice, and the drying of analog rice. Based on the results, samples of 5 (60% cassava flour, 5% gembili flour, 10% koro pedang, and 25% corn flour) as an analog of rice with the best formulations in various compositions. Based on a proximate analysis of the effect of temperature, a temperature of 75 °C is the optimum temperature for the extrusion process. The results of the physical analysis of the best analog rice in this study have a density of 0.46 g/mL, water absorption of 60.52%, and a cooking time is 46 minutes. The analog rice has the same texture, aroma, and appearance as rice in general, although the rice from the analog composite flour tends to have a savory flavor arising from koro pedang. According to the results of this study, the analog rice could be used as a substitute to lessen dependence on paddy rice.","PeriodicalId":170738,"journal":{"name":"Journal of Vocational Studies on Applied Research","volume":"44 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132971802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermopillus in an acidic state enriched by nutrients from fruit such as Ambon banana but has a short shelf life. Bananas have a role as an additional nutrient in the form of glucose which then becomes a nutrient for lactic acid bacteria. Foam mat drying itself is a drying method that is better than other types of drying because it does not require large production costs and protects the structure of the material through the formation of foam. Application of foam mat drying on fruitghurt using Ambon banana peel extract as a foaming agent is expected to increase the shelf life of fruitghurt as well as an alternative foaming agent derived from vegetable protein Ambon banana peel contains a protein content of about 0.64% when bananas experience a good level of maturity. In the manufacture of fruitghurt powder, the research method used is Response Surface Methodology (RSM) with variables changing the concentration of banana peel extract as a foaming agent, the concentration of maltodextrin as a binder and mixing time. The resulting fruitghurt powder will be analyzed for water content, total acid analysis and pH analysis. The research data were processed using minitab 19 software.
