Abstract Hotspot analysis at PMS Substation 150 kV Rawadenok Depok using the thermovision method was initiated based on hotspot events on Contact Finger phase S and Disconnecting Switch phase S. This analysis uses the Thermovisi Flir 400 tool as a means of checking high current temperatures that occur in Contact Finger phase S and Disconnecting Switches. The function of this thermovision is to measure the value of the ratio of the energy radiated by an object to the energy radiated by a black body at the same temperature and wave. Then measure the accuracy of Thermovisi starting from the value when checking, testing emissivity values, precision test values, accuracy values and repairs at hotspot points. From the results of the calculation of thermovision accuracy at Bay Cimanggis 1 & 2, it can be concluded that the temperature of the clamps and conductors shows that the conditions are still good. Where the RSM value of 27 samples is 0.4751, and has a coefficient variation (CV) of 0.1% and is categorized as good with a reference of no more than 2%, and has an accuracy value of 97.51%. Prior to the improvement of the hotspot points on Contact Finger it reached 115 oC and the DS Line S phase reached 103 oC after the temperature improvement returned to normal with Contact Finger reaching 36 oC and the DS Line S phase reaching 31.2 oC.

ABSTRACT Power flow analysis is important in planning in order to get a good electric power system. In planning the electrical system for the Tujuh Bukit Power System project with a 20kV system network located in Banyuwangi, East Java, a power flow simulation for a single line diagram will be carried out using the ETAP 12.6 software with the Newton Raphson method. The simulation results which consist of 22 buses show a voltage drop on the 0.4kV_ADR MCC Busbar2 bus and 0.4kV_50-MCC-01 Busbar2 bus. As a system improvement, the 0.4kV_ADR MCC Busbar2 bus will be installed with a 500 kVar capacitor bank to raise the voltage profile from 376.3 V to 385.56 V. While on the 0.4kV_50-MCC-01 Busbar2 bus, a 100 kVar capacitor bank is required to increase the voltage from 382.2 V to 384.16 V. After the repair, the power supplied to the system is 3589.6 kVA with a power factor of 90.5% lagging. As well as the reduction in the total value of system power losses from 58.1 kW + 242.2 kVar to 49.3 kW + 200.8 kVar. Keywords: Power flow, Netwon Rapshon, Simulation, Software ETAP 12.6

The quality of Individual Work Performance (IWP) of workers affects their work productivity in the workplace. This also has an indirect impact on improving the country's economy. The workforce IWP is influenced by human capital. Furthermore, this study was conducted to analyze the human capital of vocational high school graduates on IWP. This study used a survey method with a quantitative approach. The sample of this research was 130 alumni of vocational high school of Telkom Malang in the field of information and communication technology. Human capital indicators were knowledge, competences, skills, and innovativeness. Data collected through surveys and unstructured interviews, then analyzed with descriptive and regression techniques. The findings described respondents’ demographics. Meanwhile, the result of multiple linear regression showed that there was a simultaneous influence between the human capital indicators on the IWP. An effective contribution was determined by IWP’ skill and innovation. To better prepare graduates in their fields, vocational high schools should further increase knowledge, competences, skills, and innovativeness of their students to increase alumni work productivity in the world of work.

This also has an indirect impact on improving the country's economy. The workforce IWP is influenced by human capital. Furthermore, this study was conducted to analyze the human capital of vocational high school graduates on IWP. This study used a survey method with a quantitative approach. The sample of this research was 130 alumni of vocational high school of Telkom Malang in the field of information and communication technology. Human capital indicators were knowledge, competences, skills, and innovativeness. Data collected through surveys and unstructured interviews, then analyzed with descriptive and regression techniques. The findings described respondents’ demographics. Meanwhile, the result of multiple linear regression showed that there was a simultaneous influence between the human capital indicators on the IWP. An effective contribution was determined by IWP’ skill and innovation. To better prepare graduates in their fields, vocational high schools should further increase knowledge, competences, skills, and innovativeness of their students to increase alumni work productivity in the world of work.","PeriodicalId":31905,"journal":{"name":"Sainstek Jurnal Sains dan Teknologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79200297","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}

Abstract Currently, radar is widely used in various fields such as meteorology, military, police, shipping, aviation, agriculture, disaster, and research. Meanwhile, currently the use of radar is still in the form of sectoral, partial, and fragmented so that the use of radar data is only internal. With Indonesia's geographical condition which is very broad and the integration and distribution of radar data has not been maximized, this has resulted in the lack of geographic area of Indonesia that is reached by radar. The use or exchange of radar data still uses client-server-based information technology, and with centralized storage which has information security and privacy risk factors that are vulnerable to being misused or exploited. In addition, there is the possibility of data loss which makes it difficult to get data back, even when you have implemented a backup system with cloud or other protection, there is still a risk of complete data loss when compared to implementing a decentralized platform. Therefore, it is necessary to integrate and distribute radar data with a decentralized platform so that the radar data is not sectoral, partial, and fragmented. The integration and distribution of radar data will later be able to maximize the use of cross-field radar so that one radar can be used more optimally for all fields including meteorology, military, police, shipping, aviation, agriculture, disaster, and research. One of the technologies that can be used for the integration of radar distribution is blockchain and cryptography. Keywords: Radar, Blockchain, Cryptography.
