Abstract

Sea breezes or what are commonly referred to as monsoon winds have varying speeds, as well as different directions at each location. This study discusses the wind speed that occurs on the coast of Java Island, especially at TPI Beach, Lumajang Regency. Where this wind is a variable that has a certain speed. This wind speed is indicated to also cause changes in the shoreline where the wind, which can cause waves, hits the shore repeatedly so that it experiences abrasion. The wind data used is wind data for 5 years, from 2015 to 2020 obtained from meteorological reanalysis data for the study of wind energy potential ECWMF (European Center for Medium-Range Weather Forecasts). At this TPI beach location, the average wind speed ranges from 7-11 knots or 3-5 m/s, where the direction of arrival after data processing with the Windrose method is obtained, and east is the dominant wind comes from. In addition to the wind speed that occurred at TPI Beach, it was also discussed about the wind speed that occurred at other locations, some of which also experienced changes in the shoreline, and several other locations that did not experience the same thing but were located along the coast of Java Island both from West Java and Central Java.

Abstract

The surface water quality is getting more attention at this time, given the lower quality in some areas of West Java. Mostly the causes of the decline in water quality is due to the disposal of domestic wastewater. Oil and grease is one of the parameter in domestic wastewater that must be considered. Eco enzyme is made from the anaerobic fermentation of organic waste from fruits and vegetables which has a a versatile performance. The aims of this study is to determine whether eco enzyme made from citrus waste has the potential to be used to degrade the concentration of oil and fat in domestic wastewater. The sample used was artificially made from domestic wastewater samples which were intentionally added to oil and grease so that the initial concentration was 19.82 mg/L. In the sample that had been added 5% eco enzyme, the concentration of oil and grease managed to decrease to 13.84 mg/L after 9 days of observation, compared to that which did not add eco enzyme to 15.93 mg/L. The t Test statistical analysis showed that the oil and grease concentration reduction in the two treatments was significant, but the ANOVA analysis results showed that the two treatments did not differ significantly.

Abstract

Nutmeg oil, also known as essential oil, is an oil extracted from the seeds or leaves of nutmeg through a distillation process. Nutmeg oil has several advantages, including as an antibacterial ingredient, an additive in the perfume industry, and as a raw material for medicines in the pharmaceutical industry. In this study, the essential oil from nutmeg leaves was produced using the steam-water distillation method, where the nutmeg leaves were dried before the steam-water distillation process was carried out. As a fixed variable, 150 g of bulk cooking oil and 150 g of bimoli cooking oil were used, while as a variable, steam-water distillation temperature was used with temperature variations of 105 oC, 115 oC, and 125 oC. Samples of 1 mL, 2 mL, 3 mL, and 4 mL of nutmeg leaf oil were mixed with bulk cooking oil to compare the free fatty acid oxidation ability and peroxide value after 1 day, 3 days, 5 days, and 7 days. Analysis of the compound content of nutmeg leaf oil, free fatty acids, peroxide number, and antioxidant activity was carried out using GC-MS and 0.004% DPPH. The production of nutmeg leaf oil was obtained as much as 91 ml by steam distillation at a maximum temperature of 125 oC. Using a DPPH of 0.004 percent and a quantitative measure of IC50, the optimal antioxidant activity at 125 oC was found to be 2.03 percent. A comparison of free fatty acid numbers and peroxide values found in this study revealed that pure bimoli cooking oil had the lowest free fatty acid and peroxide values.

Abstract

UKM Jamur Raya is one of the industries that produce oyster mushrooms and is located in the village of Gesikan, Subdistrict of Gantiwarno, Regency of Klaten. The production carried out by UKM Jamur Raya is the manufacture of mushroom seeds until the planting of mushroom seeds in baglog. During the planting process, it will produce waste as a leftover baglog. Baglog waste, if only disposed of, will cause environmental problems and problems for mushroom cultivation. For this reason, it is necessary to treat baglog waste, and when viewed from the content of baglog waste, one thing that can be done is to process baglog waste into compost. The composting method used in this research is vermicomposting, which is making compost by adding worms. There are several factors in composting, one of which is the ratio of C/N values. If the organic matter is still not appropriately decomposed, then the C/N value is large and vice versa. Nitrogen content in baglog waste is very small at 0.6%, so additional materials are needed that can be used as a nitrogen source, one of which is cow dung. The most optimal vermicomposting results are found in the comparison of the composition between baglog waste and cow dung of 5 kg of baglog waste : 2.5 kg of cow dung with a C content value of 0.522%, a N content value of 20.18%, and a C/N ratio value of 20.18%.

Abstract

Currently, the Electrical Engineering Laboratory (EEL) of Universitas Jenderal Achmad Yani has a 1 kWp photovoltaic (PV) system. However, in order to fulfill the overall load, the hybrid link to the grid must be improved. The PV system and the grid must be synchronized in terms of voltage, frequency, and phase. This article presents comparative simulations of AC-AC converter models of power electronics component variants using MATLAB 2019a. Among other stages is to model the DC-DC Converter in order to enhance the output voltage of the solar panel by identifying the circuit characteristics. The second stage involves simulating the MOSFET-based DC-AC Converter circuit, which is used to convert DC to AC. The use of switching Thyristor, Gate Turn-Off Thyristor (GTO), and Insulated Gate Bipolar Transistor (IGBT) in an AC-AC phase converter to connect to the grid is examined in this range. Non-linear and linear loads are used to represent the load on the AC Cycloconverter range. Based on the results of the modeling and analysis of the PV 1 kWp system, the AC Cycloconverter in the first stage may provide a frequency of 50 Hz with a voltage drop of 235.4 V for the line and 231.9 V for the non-linear, which meets the AC Cycloconverter criterion.

Abstract

Risk is a threat that can disrupt activities or stop the production process. PT.YPT is one of the business entities engaged in the processing of tuna, especially tuna. PT.YPT itself has produced a lot of tuna which cannot be avoided, so risk mitigation is needed. The purpose of this research is to provide risk mitigation from priority risk sources that occur in tuna production activities using the House of Risk (HOR) approach and Fuzzy Logic. Data was collected by means of field observations and literature studies as preliminary research, after which the authors also conducted interviews, brainstorming and distributing questionnaires to internal companies. It can be seen that the risks that can occur in production activities are 23 risk events and 22 risk causes of which 3 risk causes have the highest percentage, namely unskilled operators (A5), less than optimal employee performance (A17) and corrosion of tools (A21). . With the Mamdani fuzzy logic approach that forms 124 IF-THEN rules, it can be seen that the three risks can be solved easily. Mitigation design is carried out to overcome these three risks by making preventive actions as many as 14 mitigation alternatives based on literacy studies and the results of discussions with the company which will be designed in the form of a traceability chart.
