The surface roughness parameter (Ra) is sufficient to determine the quality level of the surface packaging of a product, so it is widely used as a parameter to determine the surface packaging level of a product. Carbide tools dominate modern applications in the metalworking industry and are the preferred choice for metal cutting processes. Carbide tools can be improved through a coating process. In particular, the purpose of this study was to obtain surface roughness and optimum cutting conditions for dry machining of AISI 1045 materials using coated carbide tool when used in dry machining as well as for the development of research and development with research design analysis of the results of student practicum processes in laboratories, especially surface packaging material analysis. The material used is AISI 1045 with PVD TiAlN-TiN coated carbide tool. Combination machining process of cutting conditions, namely cutting speed, feed and depth of cut. Surface roughness test results on AISI 1045 test material with uncoated carbide tool surface roughness value = 9,042µm in cutting conditions: v= 235 m/min; f= 0.05mm/put; a=0.5mm; tc= 5.23 min.

The purpose of making this tool is to overcome electrical supply failures in IoT-based package receiving boxes. The system designed uses voltage sensors connected to each source of electrical energy from PLN, Photovoltaic (PV) and also batteries. After that, the voltage sensor gives a signal to the Arduino for the switching process to be carried out on each source of electrical energy. This system works, if there is a power outage from PLN, the electrical energy is supplied via PV. If the PV voltage is not sufficient, the electrical system will be supplied via batteries, so that the electrical energy in the package receiving box will always be available and can work even if there is a power outage from PLN. Based on the hybrid system test results, it was found that the voltage sensor works by detecting voltage from each source of electrical energy. When the voltage sensor does not detect a voltage source from PLN, the system will switch to PV, when the voltage sensor on the PV detects a voltage below 10 Volts, then the system will switch to battery.","PeriodicalId":491136,"journal":{"name":"Inotera","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135617627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observation data used is the exposure factor in the form of the tube voltage (kV), tube current (mA), irradiation time (s), and focus film distance (cm). The age range used is grouped based on the elderly age category established by the Ministry of Health of the Republic of Indonesia which ranges from 46 years until 85 years of age. From the data on the exposure factor and age of elderly patients, the oneway ANOVA statistical test was conducted. From the results of these statistical tests, the results obtained FCalculate value is 0,201 and sig 0,821 for Thorax AP examination and the results obtained FCalculate value is 0,790 and sig 0,476 for Thorax PA examination with the FTable value is 3,81 and the sig is 0,05.

The amplang variants produced by this store include flat fish (original), shrimp, crab, squid and seaweed. Limitations and rising raw material prices make stores often experience difficulties in optimizing production profits. This study aims to determine the number of packages in one production process for each variant produced so as to obtain maximum profit. This study used the revised simplex method and then continued with the Branch and Bound Method, which is a method used to solve linear programming problems that produce solutions in integer form. From the analysis using this method, the optimal amount was obtained as many as 317 packages per production, including 144 flat fish flavors (original), 52 shrimp flavors, 34 crab flavors, 54 squid flavors and 33 seaweed flavors with the maximum profit obtained. namely Rp. 4,125,635.
