Pemakaian sepeda motor di Indonesia sebagai mode transportasi pribadi menjadi kebutuhan pokok, kecenderungan pemakaian sepeda motor secara terus menerus terkadang melupakan performa mesin, yang membutuhkan servis ringan (tune up) secara periodik, ini menjadi sangat penting ketika melihat perfoma mesin menurun dan beberapa sparepart atau oli mesin juga terdapat masa pakai, oleh karenanya pentingnya ada sebuah alat untuk mengingatkan pengendara sepeda motor untuk servis secara berkala. Untuk itu pembuatan simulasi alat notifikasi servis ringan sepeda motor otomatis ini bertujuan untuk membuat alat notifikasi servis ringan berupa notifikasi mengganti oli dengan jarak waktu pemakaian (bulan) dan jarak tempuh kendaraan, yang terkoneksi dengan smartphone pengguna (pengendara), penelitian ini menghasilkan alat hitung digital (speedometer android) yang membaca data dari arduino nano sebagai mikrokontroler dan terhubung secara wireless dengan Bluetooth, alat ini diuji dengan 2 sepeda motor yang berbeda tipe jarak pembacaan jarum pada speedometernya, percobaan pertama menggunakan sepeda motor mio sporty yang mendapatkan hasil notifikasi muncul pada saat mencapai batas kilometer tercapai tetapi terdapat perbedaan hasil perhitungan jarak antara speedometer dan speedometer android, percobaan kedua menggunakan sepeda motor mio jet fi yang mendapatkan hasil notifikasi muncul pada saat batas kilometer telah tercapai dan hasil cukup akurat. Dan percobaan dengan jarak bulan waktu servis yang mendapatkan hasil akurat.

Water quality is an important segment in shrimp farming. The main factor of water in ponds is seen from several dimensions, including the amount of dissolved oxygen, pH, and temperature. The implementation of the farmers at the research site uses a waterwheel approach for toot oxygen, KOH/Lime for pH, and circulating water in the pond for temperature. As the main factor, water must meet standards, oxygen levels (3-7ppm), pH (7-9pH), and temperature (24-32°C). This standardization aims to produce optimal shrimp culture considering that shrimp is one of the sensitive and cannibalistic animals. For example, if the temperature or pH suddenly changes, the shrimp will eat each other, but this standardization is challenging for farmers due to limitations. Human Resources. This study aims to develop an Automatic Pond Reservoir. The system built in this study implements fuzzy logic control on the Arduino for the classification process. It triggers the Pond Reservoir to ensure the water remains in optimal conditions for shrimp growth and development. The results of the tests were 282 times, showing an accuracy of 90%.

Chronic Energy Deficiency (CED) in pregnant women is just becoming a nutrition issue during the perinatal period in Indonesia. CED occurs when energy and protein necessity, are not fulfilled by the intake consumed. CED during pregnancy has a major impact on complications for mothers, babies and perinatal mortality. CED in pregnancy is a continuation of CED in adolescence. CED screening in adolescence measuring using Body Mass Index (BMI). BMI is actually more accurate to identify the real condition of nutritional status at the time of measurement but, it unusually done because the process is more complicated, the cadres or midwives have to calculate manually. However, It is compulsory to design a simpler and practical BMI measuring instrument. This research aim to create prototype design of BMI for adolescence to prevent CED in pregnancy using an arduino. In order to help the Public Health Center (PHC) for examination CED before pregnancy. This research design utilizes a system development life cycle (SDLC), which the stages of planning, analysis, design, implementation, testing and management applied to system. The prototype design starts with planning the tools, the calibration process, the detection of the sensor, the BMI calculation consist of 4 categories (CED, normal, overweight, and obese) for Indonesian female. This categories will appear on the LCD display. This prototype can be developed into an android application, so it was very useful for adolescence and women in PHC or Integrated Post Service in Indonesia.

The interaction between humans and computers has entered a new phase, where modern humans can no longer be separated from computers in their daily lives. This interaction raises a new topic of discussion, namely Human-Computer Interaction (HCI). HCI is the intersection of cultural, social, cognitive, and aesthetic with computing and information technology. It covers a large number of problems, theories, technologies, designs, tools, environments, and human experiences in knowledge work, leisure and leisure activities, teaching and learning, and the anthology of everyday life. This study aimed to develop Eye Tracking Usability Testing System Development Using User-Centered Design Analysis Method. This study used a Tobii Eye Tracking sensor which was extracted and used as input to the GOM method. The results of this study were applications that could analyze the quality of interaction from users to website applications with a reading accuracy rate of 88%, especially in service applications, so that they could be used to make application improvements to improve services.
