<![CDATA[The aim of this study was to identify the risk of oil palm land ownership and the relationship between oil palm land area and farmers' income, the level of welfare of farmers and workers in oil palm plantations. This research can be a reference for businesses who will invest in oil palm plantations. The research was conducted by giving questionnaires to experts, the experts in question were oil palm industry players and were able to make decisions. The results of the questionnaire are processed using Fuzzy AHP to determine the degree of importance of each expert. The results obtained are the biggest risk at the actor level is the farmer, at the level of the highest risk criteria is the increase in the amount of supply while at the alternative level is the risk of quality.]]>

<![CDATA[Vegetable fat can be used as a base for making chocolate butter substitutes in making chocolate coatings. The product is also called hard butter can be obtained using coconut oil. The fats used as a substitute for cocoa butter are coconut oil, palm oil and palm kernel oil that have been obtained by hydrogenation, the hydrogenation process is used to reduce iodine numbers to obtain oil in the form of plastic solids and to increase the consistency of oils and fats to reduce color and smell and to improve stability. In this study the hydrogenation reaction of coconut oil experienced an increase in speed when the commercial catalyst composition of Pricat 9910 was added with a 0.75 gram nickel catalyst and 0.75 grams of silica which was characterized by a drastic decrease in iodine number from 12.12 to 1.94 gr I2 / 100 gr example in the reaction time of 8 hours, It contained in hydrogenated coconut oil did not change or damage when the catalyst composition used in the hydrogenation process is increased.]]>

<![CDATA[Liquid Fertilizers contain a lot of organic waste which has been decomposed and ready for consumption by plants. By utilizing the remaining vegetables, dried leaves and tofu, it is expected to increase the economic value of waste and reduce environmental pollution. Liquid fertilizer composted by anaerobic fermentation and carried out in a closed bucket (composter) with a comparison of bio-activator wastewater of tofu and EM4. The characterization of liquid fertilizer products was carried out by Nitrogen Analyzer, UV-vis spectroscopies, and AAS tools to test the levels of Nitrogen, Phosphor and Potassium respectively. The Result shown that the N total levels (0,38 %), Phosphor levels (0,06 %), and potassium levels (0,15%) of POC that made from waste water of tofu are higher than POCEM4.]]>

<![CDATA[Indonesia has millions island and big part of Indonesia is sea that is rich in marine biological resources and has the potential to be developed and optimized. One of the abundant marine resources in Indonesia is algae. Algae are plant-like protists. Algae have several important compounds, including protein, carbohydrates, fats, minerals and other useful elements. Proteins contained in algae have the potential to be used as antioxidants. In this study, the levels of protein in red and green algae were tested by using the lowry method and testing the antioxidant activity of red and green algae extracts using the Diphenylpicrylhydrazyl (DPPH) method. Algae extraction was done by maceration, which is soaking the sample in low temperature with phosphate buffer saline (PBS) pH 7. From the extraction results it can be concluded that the red algae (Rhodophyta) has the highest protein content of 5.115 ± 0.126% and the lowest protein content in green algae (Chloropytha) as big as 1.686 ± 0.430%. And from the results of the antioxidant activity test showed that all positive algae showed antioxidant activity but the green algae (Chlorophyta) had the highest antioxidant activity of 71.5946 ± 0.01612% with IC50 value 1.6114.]]>

<![CDATA[Energy evaluation is an important means for an organization to be more competitive in the global era. IKE or the intensity of electricity consumption is a term used to evaluate energy consumption in a system (building). IKE value is obtained by comparing the total use of electrical energy in building area. The evaluation process is done by collecting historical data from Kartika Husada Tambun hospital building., such as data of building area, data of the use of electricity, and the budget spent of electricity needs. From the calculation results, IKE value of the Kartika Husada Tambun Hospital in 2016 was 160,73 kWh / m2/ year, the IKE value in 2017 was 166,04 kWh / m2/ year, and 2018 was 142,79 kWh / m2/ year. This result is in the efficient category because it does not pass the IKE standard for electricity for a hospital building of 380 kWh / m2 per year. For cost savings the author recommends the application of energy-saving technology]]>
