Abstract

Botol PET (Polietilena Tereftalayt) memiliki Softening point lebih rendah yaitu 140oC dibandingkan dengan botol PC (Polycarbonate) yaitu 200 oC, maka diperlukan pengkontrolan suhu pencucian botol yang lebih rendah dan lebih stabil. Kontrol Proportional, Integral, Derivative (PID) adalah sistem pengendali yang umum digunakan di industri dengan respons waktu yang cepat dan lebih stabil dari hysterisis. Inisiatif penghematan energi dengan cara mengurangi lekukan perpipaan juga dapat dilakukan. Kelebihan jumlah lekukan perpipaan akan mengakibatkan menurunnya tekanan air penyemprotan pada ujung nozzle, kondisi ini memaksa penggunaan daya pompa yang lebih besar untuk mendapatkan besaran tekanan yang sesuai dengan parameter pencucian. Masa air juga berpengaruh besar terhadap kebutuhan energi untuk pemanasan di tangki mesin pencuci botol. Semakin banyak masa air, maka semakin besar pula energi listrik yang dibutuhkan untuk mencapai suhu acuan. Penelitian ini dilakukan pada mesin pencuci botol 5 gallon, dengan mencatat parameter-parameter washer, terutama suhu dan konsumsi energi listrik harian. Dari hasil penelitian didapat penurunan deviasi suhu dari 6o celsius menjadi 1 oC. Indeks rata-rata konsumsi energi listrik sebelum inisiatif adalah 112,63 kwh/kbtl (kilowatt hours/killo bottles) sedangkan indeks konsumsi energi rata-rata setelah inisiatif adalah 87,09 kwh/kbtl.

Abstract

This study aims to analyse the influence of risk perception, relative advantage perception, and cost perception on the interest of micro-entrepreneurs in using peer-to-peer lending in Surabaya City. This study employs a quantitative approach to test established hypotheses. The population in this study consists of micro-business actors who have received loans or utilized Fintech Peer-to-Peer lending in Surabaya City, the population size of which is unknown. The determination of the sample size uses the Cochran formula and obtained a figure of 97 respondents, rounded up to 100 respondents. The data analysis technique used is Multiple Linear Regression. The results of partial hypothesis testing found that the variable of risk perception has no effect on user interest, while the perception of relative advantage has a significant and unidirectional (positive) effect on user interest. Cost perception has a significant and unidirectional (positive) effect on user interest. Simultaneous hypothesis testing found that the variables of risk perception, relative advantage perception, and cost perception have a significant effect on user interest in Fintech Peer To Peer Lending among micro-entrepreneurs in Surabaya City. The Adjusted R Square figure is .764 or 76.4% which indicates that the role of the independent variables of risk perception, relative advantage perception, and cost perception is 76.4% on the interest in using fintech Peer To Peer Lending, and the remaining 23.6% is influenced by other factors outside this research model, therefore similar research activities in the future can examine the role of other independent variables. This research was conducted only in the city of Surabaya, so the results cannot be generalized or applied. It is hoped that further research will be conducted in a broader area, covering all regions of the Republic of Indonesia.
