Solar energy source as an alternative to gain electrical energy continues to grow. One of the utilization systems is to use the solar panels on the roof top of the house. The Household-scale of Solar System Power Plant has been widely used. This case requires skilled workers for the installation of this system. This study aims to develop a household-scale of Solar System Power Plant practice tool into a complete system. The used method begins with a literature study and then continues with the design system. The results obtained are a household-scale Solar System Power Plant tool design that can describe a complete system of the electrical energy distribution. The concept of a practical tool that previously only focused on the mechanical installation of solar panels but now become more complete with the addition of an electrical energy distribution system.

Pantauan pemberian cairan berisi vitamin dan mineral melalui botol ke pembuluh darah (infus) dengan kebiasaan yang lama, yakni (mengontrol keadaan kantong infus pada orang sakit dengan spontan. Jika ada gangguan  seperti  cairan infus tersumbat,  kemacetan  dan kehabisan  cairan  infus,  akan  berbahaya  bagi  orang sakit  jika  tidak  segera  ditangani. Penelitian ini bertujuan untuk mendeteksi cairan  infus  dengan  sensor  berat (load  cell  )  dan jika terjadi penyumbatan pada selang infus  dengan sensor Line Proximity (infrared proximity) yang dikendalikan dengan mikrokontroler Arduino nano kemudian hasilnya dimonitoring pada LCD dan smartphone Android dengan aplikasi blink. Kemudian  bila terjadi penyumbatan atau cairan infus habis  buzzer  akan  berbunyi  dengan  tujuan  memberikan informasi kepada perawat. Berdasarkan hasil pengujian yang telah dilakukan alat dapat mendeteksi berat cairan infus = 500 ml,. berat cairan infus habis = 36 ml, cairan tersumbat , monitoring pada LCD dan Android.Monitoring the administration of fluids containing vitamins and minerals through bottles into blood vessels (infusions) with long-standing habits, namely (spontaneously controlling the condition of infusion bags in sick people. If there are disturbances such as blocked infusion fluids, congestion and running out of infusion fluids, it will be dangerous for people sick if not treated immediately. This study aims to detect infusion fluids with a weight sensor (load cell) and if there is a blockage in the infusion hose with a Line Proximity (infrared proximity) sensor controlled by an Arduino nano microcontroller then the results are monitored on the LCD and Android smartphone with the blink application. Then if there is a blockage or the infusion fluid runs out the buzzer will sound with the aim of providing information to the nurse. Based on the results of the tests that have been carried out, the tool can detect the weight of the infusion fluid = 500 ml. the weight of the infusion fluid is used up = 36 ml, the fluid is blocked, monitoring on the LCD and Android.

Current cybercrime or cybercrime is very alarming. This study was conducted because more and more people who have cases that belong to cybercrime. According to preliminary data, cybercrime has occurred in the city of Manado. The city of Manado as the capital of North Sulawesi province has also been a victim of crime from cyberspace. What kind of cybercrime is experienced by the people of Manado City who want to be traced in this research by developing online survey system that can be used to get the cybercrime information quickly, accurately and accurately? By using waterfall system development method then designed an online based survey system and performed performance testing of system functionality that was built with the help of scale linker 1-5 to help calculate the percentage of respondents' answers. The result of this research can be an online based survey system to obtain information characteristic cybercrime experienced by Manado city residents and the results of system testing with data analysis as much as 73.33% of respondents stated that the application is easy to use, 56.66% respondents stated that survey questions are easy to understand and 70% of respondents stated that the application is appropriate for the survey.

Research regarding scheduling and power distribution system on diesel power plant in North Sulawesi using genetic algorithm has been done. This research was conducted to provide a new approach for scheduling and power distribution in North Sulawesi. Method of genetic algorithm is used in this study to address the problem of scheduling and distribution system of diesel power plant. Method of genetic algorithms is a heuristic search algorithm that mimics the mechanisms of biological system. Under this concept, the problem will be solved using the pattern of biological evolution. Solutions for solving problems will apply the method of selection, crossover, and mutation. Scheduling using genetic algorithm can optimize the scheduling done by by PT. PLN North Sulawesi, Minahasa System AP2B. Based on the results and the discussion it can be concluded that the genetic algorithm can be used as an efficient method for scheduling and power distribution system on the diesel power plants in North Sulawesi. Keywords: Genetic Algorithm, Scheduling, Power Distribution, Power Plant North Sulawesi. AbstrakPenelitian menyangkut penjadwalan dan distribusi daya pada pembangkitan listrik tenaga diesel di Sulawesi Utara dengan menggunakan algoritma genetik ini telah dilakukan untuk memberikan pendekatan baru terhadap permasalahan pembangkitan ini. Metode algoritma genetik adalah algoritma pencarian heuristic yang meniru mekanisme evolusi yang terjadi secara biologis. Melalui konsep ini, masalah yang akan dipecahkan didekati dengan pola evaluasi biologi. Solusi pemecahan masalah yang terbaik menerapkan metode seleksi, crossover, dan mutasi. Penjadwalan dengan menggunakan algoritma genetik dapat mengoptimasi penjadwalan yang dilakukan oleh oleh PT. PLN Sulawesi Utara, AP2B Sistem Minahasa. Berdasarkan hasil dan pembahasan ini maka dapat disimpulkan bahwa algoritma genetik dapat dijadikan metode yang efesien untuk penjadwalan pembangkit dan distribusi pembebanan pada sistem pembangkit listrik tenaga diesel di PLN Sulawesi Utara.
