Authors: Purwondho Rudy , Sudrajat Ajat , Handoko  
Published: August 2021

Abstract
The working principle of an internal combustion engine, in general, is to convert chemical energy from liquid fuels to mechanical energy. The type of fuel commonly used by internal combustion engines is fossil fuel, which until now has been increasing in use while its supply is running low. The presentstudy is to conduct research in the field of new and renewable energy as an alternative fuel to replace fossil fuels. Hydrogen is a new form of energy carrier that could be obtained through the process of water electrolysis and is a promising fuel supplement in the future. Hydrogen production through the electrolysis process continues to be develop to help use environmentally friendly fuels and can have a positive impact on engine performance and exhaust emissions. However, to produce consistent and quality HHO gas output, the current HHO gas generator still needs tobe improved especially for the production volume. The purpose of this research will be directed to the development of the effective electrode plate system in producing HHO gas. In order to improve the quality and volume of HHO gas production, it was found that the level of surface roughness and the contact angle of the material should be increased through grinding and polishing processes. In this research, various SS316L electrode plates with different surface roughness were made for the analysis of HHO gas production to match the expected volume of HHO gas production. Various conditions of surface roughness of the electrode plate are carrying out by grinding and polishing the surfaces of both sides of the electrode plate to a uniform roughness level.

Authors: Pratama Febrian Hera , Andhika Rully , Latief Yusuf 
Published: August 2021

Abstract
A construction company is a business that offers services for construction and/or construction works. In a duration from July 2017 to July 2019, 23 accidents have occurred that are related with infrastructure projects conducted by highly qualified national construction companies that are certified for ISO quality standard, among which are several national strategic projects. These events cause physical and material losses that affect the level of confidence towards the quality of the work results. These events can occur because the application of ISO is not followed by the development of a good quality culture, and there is no ownership of quality culture maturity. For this reason, the objective of this research is then to identify the variables of quality culture maturity in construction companies so that it can be used to measure maturity level of quality culture, and to obtain a strategy to increase the said maturity level quality culture in construction companies, in an effort to reduce the amount of potential construction failures.

Abstract
In an oil drilling area, there are two oil drilling companies that have obtained permits to drill. As time goes by, the availability of existing petroleum decreases. To anticipate natural resources the government only prioritizes one company. Competition occurs between the two of them to explore petroleum from the ground so that they can drill. The purpose of this study is to provide an overview, how to make a system dynamics model related to the problem of oil drilling as an increasingly limited natural resource, by taking the case of the relationship between drilling companies in facing business competition. The method used is system dynamics with a standard model of mutual difficulties (drifting goals). The result obtained is a system dynamics model that can be used to demonstrate the behavior of a simulated petroleum drilling model to get an overview or condition of the limitations of petroleum and future availability.

Authors: Romulo Andreas , Meindrawan Bayu , Marpietylie  
Published: August 2021

Abstract
Ice cream is a type of sweetened frozen food, which use cow’s milk and sugar as main ingredients. Due to its high sugar and fat content, the excessive consumption of ice cream could contribute to the significant health impact, especially for those who suffer diabetes. Moreover, some people could not consume the ice cream because of its inability to digest the lactose content in cow’s milk in their body. In recent years, there is some great innovation to replace cow’s milk as the main ingredients of ice cream with other milk substitutes. In order to obtain the ice cream-like characteristic, several food additives are added to ice cream. The formulation of the ice cream and choosing the proper materials are the key factor to produce desirable ice cream. This manuscript summarized the development of ice cream products from different ingredients of milk substitutes that influence the overrun, viscosity, and melting resistance of the products.
