Abstract

Abstract— The exact estimation of the number of colonies or Colony Forming Units (CFUs) is frequently used in microbiology research, particularly in the field of bacteria. The number of colonies that develop per gram or milliliter of sample is estimated by multiplying the number of plates, the dilution factor, and the volume used [1]. Counting the number of bacterial colonies can be used to determine a bacterium's growth rate. The cup count method is commonly used to accomplish this manually. An instrument called a colony counter can help with colony counting utilizing the cup count method. This technology works by using a pen connected to a counter to mark the colonies that have been counted. However, because the colony size is tiny and the number of colonies counted is huge, this can lead to inaccuracies, and the same difficulties can happen with manual colony computations. Digital image processing technology has been extensively developed for use in a variety of fields. Researchers had previously undertaken a similar study that attempted to count bacterial colonies and had a 94 percent accuracy rate, but some colonies were not spotted because they were filtered during preprocessing, so they looked into it further.

Abstract

70% of building fires in Indonesia are caused by electrical short circuits, the rest are caused by other things such as negligence and also gas. Electrical short circuits contribute to the biggest problem in cases of building fires in Indonesia due to concern for maintenance and checking which is often missed due to problems with routine and periodic checking schedules that are not monitored in a lifetime or continuously. One of the methods used to overcome this problem is to continuously monitor the measurement values on the electrical sub-panels in real time. Manual checking is no longer effective due to electrical problems. One minute ago we checked and we can conclude that the panel is in good condition and safe. Because electricity can suddenly have problems without us realizing it and it really needs to be handled extra quickly to take action to cut off the power lines so that short circuits or hot copper sections do not occur which can cause panel fires and can also cause building fires. With today's increasingly sophisticated digital technology, we can innovate by implementing IoT (Internet Of Thing) using the Bynk Android Application as a remote control for monitoring load values and also being able to trigger 3-phase power lines using only a smartphone anywhere as long as the internet is connected so that when If there is an electrical problem with the sub panel inside the building, it will be handled/disconnected immediately. From the research results obtained, the Solid State Relay component can be combined with a microcontroller as the main control line to cut off large electric currents, where the microcontroller uses a 5 Volt input control and SSR (Solid State Relay) uses a 3 Volt - 32 Volt output so that it can be modified and can cut off and monitor traffic only with a smartphone using the Blynk Application.

Abstract

Intisari— Perkembangan teknologi khususnya dibidang robotika saat ini sangat pesat, Salah satu bentuk aplikasi dari teknologi robotika yang erat kaitannya dengan sistem kontrol adalah wheel mobile robot. Beberapa metode dapat dilakukan untuk mendistribusikan gas alam salah satunya dengan pipa. Distribusi gas alam dengan menggunakan pipa sering mengalami kendala kebocoran yang disebabkan usia dari pipa distribusi yang sudah cukup tua. Untuk mempermudah pemantauan pipa gas yang berada di bawah tanah digunakan robot 6 WD (wheel drive) yang memiliki 6 roda dan penggerak pada setiap rodanya untuk mengatasi medan yang berat. Pergerakan dari robot 6 WD mengacu pada sensor ultrasonik SRF HC-SR04, metode ini dinamakan wall following. Sensor gas tipe TGS dari figaro dimanfaatkan untuk mengetahui adanya kebocoran gas pada pipa atau tidak. Selain itu, robot ini juga dilengkapi dengan kamera untuk mengirim gambar kerusakan pipa pada user agar dapat segera dilakukan perbaikan. Arduino Mega 2560 digunakan sebagai otak pada robot 6 WD yang bertugas untuk mengolah data yang masuk dan memberikan instruksi pada robot 6WD. Pengiriman data dari robot 6 WD pada pengguna meliputi, data sensor gas, data sensor kompas, data sensor jarak dan gambar kerusakan pada pipa. Seluruh data dapat dilihat pada GCS (Ground Control Station). [TRUNITIN CHECK 20%, 26042017]
