However, there are many traditional breeders looking for cows that have reached puberty, but the cow's body is still thin. This could be due to the absence of records in monitoring the weight growth of cows so that feeding becomes less precise. Based on these problems, a system was designed that helps farmers in managing their livestock management by recording the progress of each beef cattle that are kept, regulating cattle feeding so that it is more optimal, and knowing the cost benefits of cattle that are kept based on the growth of cow body weight. This system uses two load cells to weigh cows. The weight of the weighed cow can be stored in the web application database. The main function of this system is to be able to calculate and display the cost of benefits of cattle based on the growth of the cow's body weight. Based on the tests carried out, the system can weight cows using two 500kg load cells with an error value of 3.61%. The system can check cow data using keypad input with an average time of 3.99 seconds and store cattle data in the database with an average time of 4.99 seconds. The system can calculate the cost of cow feed needs in one month and income due to changes in cow weight with a 100% success rate.</p> Emyr Riyanda Azra Dodon Yendri Adrizal Copyright (c) 2023 Emyr Riyanda Azra, Dodon Yendri, Adrizal 2023-10-31 2023-10-31 4 02 93 106 10.25077/chipset.4.02.93-106.2023 Sistem Pemberian Air Dan Pupuk Pada Tanaman Melon Menggunakan Irigasi Tetes <p><em>Melon is one of the high value crops, so it needs to be empowered. Melon growth is closely related to the state of water, soil pH, and nutrients. A mismatch in water content causes stunted growth. Melon grow well in soil with a pH of 6-7, where nutrients are easily absorbed. Human has limitations in watering, fertilising and controlling the pH of the soil manually. Therefore, a system for automatic watering, fertilisation and pH control with drip irrigation is needed. This system uses Arduino Mega2560 as a microcontroller, RTC for scheduling watering and fertiliser, pH sensor for controlling soil pH, water level sensor to measure the contents of the container with notification to Telegram. In this research, the system succeeded in watering and fertilising on schedule with 100% time accuracy, and controlling soil pH with a pH measurement accuracy of 95.57%. The system also successfully detected the solution running out and sent the notification to Telegram. The melon plants grow faster using the system than manually, with a difference in plant height of 1.029 cm on day 7. Thus it can be concluded that the system for automatic watering, fertilising, and pH control of melon plants has been successfully built.</em></p> Ella Alfareza Tati Erlina Copyright (c) 2023 Ella Alfareza, Tati Erlina 2023-10-31 2023-10-31 4 02 107 118 10.25077/chipset.4.02.107-118.2023 Rancang Bangun Perangkap Tikus Jenis Falling Floor Trap Menggunakan Dengan Notifikasi Android Berbasis Mikrokontroler <table width="662"> <tbody> <tr> <td width="393"> <p>This Study aims to create a Falling Floor type&nbsp; of Rats Trap that can automatically catches and kills rats that enter the trap and then, it will send a notification to the user’s phone via telegram chat app also automatically set it back to steady state again once the times given to kill the rat is over by using a sensor while system is controlled by a microcontroller.

BSF flies only need to drink, and do not eat. BSF fly feeding should be given regularly based on the ambient temperature around the cage. At this time, BSF fly breeders tend to have a busy and congested schedule so the cage spraying schedule is neglected. In addition, human negligence factors such as laziness and forgetting also make the spraying schedule irregular. Spraying of the cage was done manually using a plant sprayer. Therefore, research was conducted on the design of a microcontroller-based BSF fly drinking system. This system can perform automatic spraying of BSF flies based on the high and low temperatures around the cage, as well as provide notifications to the telegram of the BSF fly owner. Based on the study's results, this system detects the temperature around the cage using a DHT22 sensor and then sprays drinking BSF flies with the help of a DC pump. This system can be connected to the internet to send notifications that the cage has been sprayed via the telegram application of the cage owner.</p> Putri Utari Ratna Aisuwarya Resti Rahayu Copyright (c) 2023 Putri Utari, Ratna Aisuwarya, Resti Rahayu 2023-10-31 2023-10-31 4 02 141 155 10.25077/chipset.4.02.141-155.2023 Rancang Bangun Alat Pengembalian Buku Perpustakaan Secara Mandiri Berbasis Single Board Computer <p>the process of borrowing and returning library books usually requires a librarian to go through this process, of course this requirement can cause delays in returning books due to library holidays and the difference in free hours from the library and library members. so this research aims to make it easy for library members to be able to return books independently using a storage box that can be done by the system. in this book return box using a raspberry pi 3b+ as a data processing center and using the pi camera to capture the book cover made on the book return box. the security system in this return box uses a selenoid door lock as an automatic door lock which will be routed by a relay and uses rfid as the identity of books, members and librarians. in this study the system can store and return books using the K-Nearest Neighbor (KNN) method with an accuracy of 95% with a processing time of 6.9s</p> Nazri Ilhamzah Akbar Budi Rahmadya Rahmi Eka Putri Copyright (c) 2023 Nazri Ilhamzah Akbar, Budi Rahmadya, Rahmi Eka Putri 2023-10-31 2023-10-31 4 02 156 167 10.25077/chipset.4.02.156-167.2023 Rancang Bangun Kotak Obat Pintar Berbasis Mikrokontroler <p>The increase in the number of chronic diseases and their complications to the increase in mortality (death) caused by the low level of discipline in taking drugs.
