Abstract

Water is needed by humans life, so water quality is a quality requirement of human health. A Few years ago, people are familiar with ionized alkaline water which has a pH of more than 7. Consequently, it is necessary to test the quality of ionized alkaline water following Ministry of Health Regulation (PERMENKES) No. 492 of 2010. Samples were taken from 8 brands of ionized alkaline water in the South Tangerang. The measurement method is procedured with the Indonesian national standard method (SNI). The results of the physical and biological analysis show that 8 brands taken as samples comply with the quality standards with applicable regulations. The result of the chemical show that indicate that 3 samples do not fulfill the PERMENKES requirements, namely pH, pH concentrations ranging from 7.61-8.90 with the required quality standards of 6.5-8.5. Whereas other chemical parameters of Manganese, Iron, Ammonia, Nitrite, Sulfate, Chloride, and Hardness fulfill the specified requirements. The results concluded that only five of the eight brands of ionized alkaline water were suitable for consumption by the applicable regulations.

Abstract

In carrying out various activities today, it cannot be separated from the fuel. As we all know, fuels that are still commonly used today are fossil fuels whose energy resources are running low. Not only that, fossil fuels have also been shown to produce air pollution. Unhealthy air conditions can certainly reduce human life expectancy. In order to make the clean environment and not polluted by the air pollution, there must be environmentally friendly fuels. The answer for this kind of fuels is hydrogen which comes from nonfossil. One way to obtain hydrogen is an electrolysis reaction. Water can produce hydrogen through electrolysis. Just a few liters of water, it can produce ten to twenty thousand liters of hydrogen gas per hour. The use of Hydrogen as a non-fossil fuel has been proven to be environmentally friendly and free of carbon monoxide. Healthy air and a clean environment are certainly our responsibility. It's time to switch by using hydrogen fuel.

Abstract

The concept of Production Planning and Control is closely related to logistics activities, including in determining the production of a product. Production planning and control aims to get a complete picture of how to plan and control production in the industry of each company, so that all costs can be reduced. Production planning, Rough Cut Capacity Planning (RCCP), Material Requirement Planning (MRP), Capacity Requirement Planning (CRP), and Line Balancing are some of the steps that need to be done in providing an overview of the production planning and control system at the "Tamiya" Company. Production planning results in the amount of "Tamiya" production in a certain period by considering SEE and the most appropriate production strategy that results in total costs. MPS validation considerations are the output of the RCCP calculation, a comparison of the ratio of the required capacity to the capacity of the company. The MRP stage reduces production due to material unavailability, the result is the best material scheduling based on the lot sizing method which provides the lowest cost. CRP generates Planned Input and Planned Output per work station to see the balance between load and capacity. Line Balancing functions to balance assignments through the Ranking Position Weight (RPW) and Presedence Diagram methods, getting results in the form of updating the layout of the assignment so that the efficiency of the production line can be improved

Abstract

Currently, the university is one of the actors in the use of chemical substances for educational purposes in practicums and research. Based on the survey, it is known that the processing of laboratory waste, especially organic wastewater, is not optimal. This needs to be considered considering that generally the university is located in the residential area so that if the wastewater pollutant, it will certainly risk causing serious impacts on the community. A wastewater treatment technology using photocatalysis can process toxic organic substances into simpler and environmentally friendly substances. This research includes several stages, namely the collection of waste organic compound from practicum and research activities, sampling of laboratory waste, and testing of waste treatment and analysis of the total content of organic compounds from permangnometric titration wastewater treatments. The results showed that the TiO2 photocatalyst with a composition of 0.8% (w / v) was able to reduce the content of organic compounds in the waste sample by 96.19027% in the reaction time of 4 days.

Abstract

The culinary area located in Galuh Mas Karawang is a strategic area that is very busy and never empty of visitors. The purpose of this study was to determine the optimal strategy between the three meatball with chicken noodle culinary competitions, namely Baso Ambon, Baso Malang and Baso Sopo Nyono. The research sample was 167 respondents who were only visitors and direct customers from the three meatball culinary places in March 2021. Based on the results of data processing with this method, it is found that the optimal strategy between Baso Malang and Baso Ambon has a meeting point of maximum value equal to the minimum value called a saddle point of 0.067 on row X2 and column Y1 which means Baso Malang uses a better service strategy than Baso Ambon. Meanwhile, Baso Ambon uses a more affordable price strategy than Baso Malang. Then for Baso Sopo Nyono and Baso Ambon have a saddle point of 0.284 on row X3 and column Y1, meaning that Baso Sopo Nyono uses a more complete facilities strategy than Baso Ambon.

Abstract

The study of thermal energy produced by the Sulzer ZAV 40S diesel engine using Marine Fuel Oil (MFO) can affect the engine combustion process because of the change in fuel chemical energy into internal work. The heat energy generated in the diesel engine where the ignition process when the piston approaches the dead point is then followed by the presence of fuel, namely MFO. The fuel will be sprayed through the nozzles into the combustion chamber. This will result in a complete combustion process where the composition of the mass of air and fuel in the cylinder will generate heat due to the high temperature. The results of the calculation that the need for fuel and air to produce the energy value (Q) of this diesel engine is 808.33 Kcal and the power (Ni) is 4,602.09 PK in every second while the mass of MGO is 5 Kg and air is 130 Kg in every minutes for continuous rotation of 500 rpm.

Abstract

discoloration is the result of the action of endogenous polyphenol oxidase (enzymatic browning) followed by spontaneous polymerization of quinonoid compounds with other food components. Currently, the use of sulfite agents is the most widely used chemical approach to control browning of foods. However, consumer awareness of the risks associated with sulfites and growing regulations make sulfites an alternative. Efforts should be made to reduce the degree of browning of porang tuber chips caused by enzymatic non-enzymatic browning. The purpose of this study was to study the alternative use of sulfite as an anti-browning agent against the whiteness value of porang tuber chips. The alternative type of sulfite used is ascorbic acid. Ascorbic acid concentration (2, 5 and 7.5%) and immersion time (30, 60, 90, 120, 150 and 180 minutes) were selected as independent variables. The best condition for preventing browning of porang tuber chips was obtained by using 5% ascorbic acid at a time of soaking for 180 minutes and obtained the highest whiteness value (79.41). Keywords: anti-browning agents, lightness, chips porang
