Abstract

All of tennis athletes can play tennis properly because they practice for hours, months and even years. There are many ways that can be done to practice playing tennis, namely by using a wall or with the help of a ball throwing machine. Several tennis ball throwing machines developed by researchers have been found, although they are not optimal. Basically, the principle of throwing a tennis ball is almost the same as throwing a table tennis ball, namely using an electric motor as a trigger for the throwing motion. For reference and source of knowledge, the researchers conducted a perc ejection machine by combining a machine with a joystick-based remote control using an Arduino type microcontroller, an electric motor type driving motor. With this combination the machine can be adjusted for vertical and horizontal movement and can adjust the speed of the ejector by programming on the side of the microcontroller. The results of the design are drawings of arrangement, drawings of parts, sizes and materials used and drawings of a three-dimensional machine with a size of 100 cm x 70 cm x 140 cm.

Abstract

Sarolangun Regency is a district that has the potential for gold metal mineral natural resources. This potential causes many illegal gold mining activities (PETI) in the area. It is also suspected that PETI activities can cause environmental damage and pollution in the activity area and downstream from the PETI location. Environmental pollution that occurs is caused by the disposal of gold processing waste (tailings) into water bodies and groundwater. Waste generated from gold mining activities mainly contains mercury (Hg) and lead (Pb). The purpose of this study was to analyze the level of heavy metal pollutants (Hg and Pb) using the contamination factor (CF), the pollutant load index (PLI), and the geoaccumulation index (I_geo) on former PETI in Sarolangun Regency. The sampling technique was carried out by a purposive sampling technique and the sample taken was soil. Heavy metal concentration data will be calculated using the CF, I_geo, and PLI index formulas.  Hg concentrations were 0.86 mg/kg, 0.77 mg/kg, and 0.80 mg/kg in three sampling areas, and lead concentrations were 0.51 mg/kg, 0.54 mg/kg, and 0.53 mg/kg. Based on the analysis of CF calculations and I_geo, Hg(mercury) has more potential to become a pollutant at the study site (CF>6), (2<I_geo<3). On the other hand, the study site was not polluted by lead based on the CF value and geoaccumulation index. The overall PLI calculation of Hg and Pb stated that the research location was not included in the polluted category with a PLI value <1.

Abstract

COVID-19 has become a pandemic and has caused concern for people worldwide. The rapid spread of the disease requires health care providers and health workers to be able to diagnose precisely, quickly, and accurately to speed up the stages of treatment. Reviews and procedures for implementing clinical diagnostics of SARS-CoV-2 have not been widely reported. This study aimed to analyze the differences in diagnostic procedures for COVID-19 virus infection using the smear method at the Graha Medika Clinic. Observational descriptive research was conducted in July 2022. The research took place at the Graha Medika Clinic by screening patients who took the COVID-19 examination using the smear method (antigen swab, PCR swab, and rapid antigen). The study results obtained that one (10%) out of ten people infected with COVID-19 were on the antigen swab examination. There are differences in clinical diagnostics of COVID-19 infection using the smear method, namely in the antigen swab, the test time tends to be fast compared to PCR but is somewhat less accurate; rapid antigen only detects viruses that have taken place acutely with low accuracy while PCR is used as an accurate diagnostic by identifying proteins and viral glycans molecularly, has excellent accuracy but requires experts and a long time. The clinical diagnosis of COVID-19 infection using the smear method is currently adequate. The recommended examination method for the COVID-19 examination is carried out in stages, starting from rapid antigen, antigen swab, and PCR swab. PCR swab examination is the gold standard for detecting viral genetic material.

Abstract

Garbage is still a problem experienced by the community, due to poor management and processing and lack of awareness of the community itself. The waste generated by the Manukan Kulon TPS is still managed conventionally. Garbage is temporarily stored and then disposed of to the landfill using a garbage truck. One of the efforts that can be done in order to overcome the waste problem is to redesign the Manukan Kulon Temporary Disposal Site into a Reduce, Reuse, Recycle (TPS 3R) so that the burden of waste that is accommodated in the TPA is reduced. This plan projects the age of the 3R TPS for the next ten years, so that the highest volume of waste generation in 2022 will reach 78.53 m3/day with a population served by 13,744 people. Planning The 3R TPS consists of a sorting area, a stall packaging area, an organic waste storage and enumeration area, an organic waste composting area, a leachate storage area, and a compost sieving and packaging area, and is equipped with an office, cart parking area, residue area, storage warehouse. tools, toilets and prayer rooms with a total building area of ​​527.75 m2. The budget plan (RAB) that must be spent for this plan is Rp. 1,080,200,973.

Abstract

Liquid waste from the tofu industry contains a lot of organic matter, the high content of this organic material will result in high BOD and COD values ​​in the waters and can have a bad impact if not handled properly. One alternative that is commonly used to overcome this problem is to use a photocatalyst degradation method. This study aims to determine the reaction kinetics which includes the determination of the reaction rate constant and the reaction order in removing the COD content of the resin-immobilized TiO₂ photocatalyst. This study presents the reaction kinetics of RIPT with catalyst, TiO2, catalyst mass (10gr, 20gr, 30gr), and RIPT mass (5gr, 10gr, 15gr). This research was conducted by making immobilized TiO2 photocatalyst resin and then entering 1000 ml of tofu industrial waste and the obtained RIPT-resin into the reactor in which stirring occurred using a test jar. Based on the results of the study, the best value for the reaction rate constant was obtained by the mass variation of RIPT (15gr). Meanwhile, the best value constant of reaction rate was obtained by mass variation of 30 gram TiO2 catalyst, with the result that the reaction rate constant value of RIPT- and RIPT-TiO2 30 grams was 0.0101 minute-1.

Abstract

Tofu liquid waste contains organic material, namely BOD which is quite high, if it is directly discharged into water bodies, it will reduce the carrying capacity of the environment. This causes the carrying capacity of the environment to decrease and ecosystem performance to become unbalanced, so that further processing is needed, namely Resin Immobilized Photocatalyst Technology (RIPT). In this study, the BOD reduction process was carried out with resin, photocatalyst, and immobilization. The process of immobilizing the catalyst against the resin aims to expand the surface and maintain photocatalyst activity. The type of catalyst used is ZnO and TiO2. After obtaining the RIP (Resin Immobilized Photocatalyst), then the RIP was added to the wastewater and the BOD concentration in the tofu wastewater was calculated. The resin capacity is calculated with the aim of knowing the ability of the resin to reduce the concentration of BOD. From the research that has been done, it can be concluded that the highest resin capacity when using ZnO catalyst is 0.3159 g/L and 0.2806 g/L using TiO2. The effluent parameter concentration is directly proportional to the resin capacity. As the sampling time increases, the resin's ability decreases.

Abstract

The increasing number of people in the world has caused the air to be increasingly polluted. In everyday time of day the exhaust gases from transportation are mostly inhaled from the combustion output using fuel whichhas relatively high levels. Carbon monoxide has a negative influence on the body because CO is able to bind through blood cells or hemoglobin which transports oxygen to all the body and interferes with the distribution of oxygen to the blood. This study aims to find out the average picture of the level of CO concentration and the influence of the number of motorized vehicles on the level of CO concentration on Jalan Kedung Cowek Surabaya.In this study, the CO measurement used aeroaqual tools. The results of research conducted for 1 week on Tuesday (representing weekdays), Saturdays (representing half-working days) and Sundays (representing holidays) showed differences in CO concentration and vehicle volume at each time”. In the morning and evening, the average CO concentration tends to be higher than during the day. From the results of the Multivariate Anova analysis, it can be concluded that the existing time difference greatly affects the concentration of CO and the volume of the vehicle produced. In addition, CO concentration is also influenced by meteorological factors such as temperature, direction and wind speed.

Abstract

The impact of landfilling is the emergence of leachate which contains suspended and dissolved solids, organic and inorganic chemicals which are quite high and have the potential to cause environmental pollution. The lack of variety of leachate treatment makes many researchers start looking for effective ways to reduce leachate. One of the methods proposed is to use decomposer organisms, namely Black Soldier Fly (BSF) insects. The purpose of this study was to determine the effectiveness of Black Soldier Fly (BSF) larvae in processing leachate from organic waste from TPS. The research method used growing media or a mixer in the form of chicken feed and variations in leachate concentrations, namely 25%, 40%, 55%, 70%, 85%, and 100% (L25, L40, L55, L70, L85, and L100). The results showed that Black Soldier Fly (BSF) larvae were quite effective in processing leachate for 22 days. The concentration of leachate is quite influential in leachate processing, the greater the concentration, the higher the level of effectiveness. The effectiveness of leachate treatment using BSF larvae is based on the highest media weight loss, namely in the L100 treatment, which is 57.13% and the lowest in the L25 treatment, which is 48.49%.
