Abstract

Telah dilakukan modifikasi terhadap surveymeter gamma Dosimeter 3007A. Surveymeter ini merupakan surveymeter analog, sehingga diperlukan perangkat antar muka untuk melakukan akuisisi data. Akuisisi dari surveymeter dilakukan dengan menambah modul penguat tegangan dari 0 – 200 mV menjadi 0 – 5 V . Tegangan ini merepresentasikan laju paparan dari 0 – 5 mR/jam. Selanjutnya sinyal analog 0 – 5 V, sebagai sinyal masukan ke perangkat PLC T100MD series. Data berupa sinyal analog diolah dan ditampilkan pada lokal display PLC. Untuk pemantauan dari jarak jauh data dikirim ke komputer dari PLC melalui jaringan ethernet. Surveymeter ini setelah dilakukan modifikasi dapat berfungsi untuk melakukan pemantauan dari jarak jauh, bahkan dengan memakai jasa ISP (Internet Service Provider) pemantauan dapat dilakukan kapan saja dan dimana saja asalkan masih terhubung dengan jaringan internet.

Abstract

Polential of Micro Hydro Power in remote areas is the most realistic as the primary energy for electricity generation. Potential energy become a growing alternative for the region to diversify its electricity supply. The issue of global warming that encourages the use of renewable energy in an effort to prevent damage to the natural speed of following up a global agreement under the Kyoto Protocal. One program in the reduction of exhaust emissions is the Clean Development Mechanism (CDM). Through this concept all the activities of energy usage can be measured and calculated potential relation with the exhaust emissions.CDM potential measurement begins by defining the instrument to be used. MHP is the power output is a fixed value that is used as a reference that will measure the impact if generated by fossil energy utilization. This step is an approach that shows how the potential for greenhouse gas emissions that can be prevented if the electrical power needs supplied by renewable energy-based generation.The sample of study is MHP Cinta Mekar in Subang district indicates that this location was proposed as a viable small-scale projects under the CDM. MHP is able to produce electrical energy of 120 KW. CDm potential is calculated are the reduction of fossil energy consumption of 1.5 tons per day. In addition to equality of use of fossil fuels for electrical potential energy also has the potential to reduce environmental pollution by 1474.2 tons / year of CO2.Keyword : CDM, MHP, Energy, Pollution

Abstract

AbstractThe prolonged situation of the Corona Virus Pandemic (Covid-19) has made changes in consumer behavior around the world, including in Indonesia. The limitation of community activities in fulfilling the need for daily products and services with PSBB makes people look for alternative shopping solutions through the marketplace to meet their daily needs, both goods and services. This situation is used by marketplace companies to increase the number of public spending transactions on their marketplace platforms. This is evident from many marketplace companies that have drastically increased their sales transactions. Keywords: Covid-19 Pandemic; Marketplace

Abstract

As time goes by PT Pumas Rotua Gemilang has experienced a lot of development with increasing production, it requires more labor, in the early days there were 200 workers until now it has reached approximately 400 workers, so the need for employee performance appraisal is needed according to company standards aims to carry out the process of assessing the feasibility of appointing employees to permanent employee status. However, the assessment is still conventional, seems slow and inaccurate, so it is necessary to have an employee appointment decision support system designed with PHP programming and mySQL as the database. The application of research using the AHP (Analytic Hierarchy Process) method the criteria used are Attendance, Knowledge, Cooperation, Work Quality and Discipline, the process begins by determining the criteria, eigenvalue. The final result of the AHP method shows the transparency of the feasibility of appointing employees with their respective values and has a certain weight according to the priorities of the company.
