Fuzzy Tsukamoto is one method that is very flexible and tolerant of existing data. Fuzzy Tsukamoto has the advantage of being more intuitive, accepted by many, more suitable for the input received from humans rather than machines. Microfinance institutions are specialized financial institutions established to provide business development services and community empowerment, either through loans or financing in micro-scale businesses to members and the community, deposit management, and the provision of business development consulting services that are not solely for profit. The purpose of this study is to apply the fuzzy Tsukamoto method to determine the level of financial distress in microfinance institutions in the city of Medan based on the variables Liquidity Ratio, Age Firm, and Cumulative Profitability Ratio, Profitability Ratio, Financial Structure Ratio, Capital Turnover Ratio.
Abstrak-Pada penelitian ini dirancang sebuah sistem kontrol penyalaan lampu dan perangkat elektronik untuk meniru keberadaan penghuni rumah. Sistem dirancang untuk mengontrol penyalaan beberapa lampu dan perangkat elektronik secara acak. Hal tersebut bertujuan untuk menimbulkan kesan bahwa rumah yang ditinggalkan seakan akan ada penghuninya. Sistem keamanan ini bekerja dengan cara membangkitkan sebuah bilangan acak setiap 15 menit. Setiap bilangan acak yang dibangkitkan mengacu kepada peralatan listrik yang dikontrol. Peralatan listrik rumah yang telah menyala akan padam ketika lamanya waktu yang ditetapkan tercapai. Sistem yang dirancang terdiri dari Arduino, catu daya, RTC dan interface perantara dengan peralatan listrik. Sistem telah diuji selama 5 hari waktu normalisasi terhadap sistem kontrolnya dan sistem miniatur rumah. Miniatur rumah dibuat untuk mewakili kondisi rumah yang sebenarnya. Konsumsi daya listrik perhari dari sistem yang dibuat adalah 0,42 kWh.

The designed system is able to turn on and turn off the equipments randomly for treating the availability of the owners in their houses. The system generates a number randomly every 15 minutes. Each number associated with bulb or electrical device in the controlling list. The electrical devices will be ON or OFF based on specific duration times. The system is realized using an Arduino board, an RTC, power supply unit, and interface circuit of Arduino and electrical devices. The designed system has been tested for 5 consecutive days normalized to 2 hour normal time on the control device and house miniature. The miniature is used to mimic condition the real house. Electric consumption estimated about 0.42 kWh per day
