Abstract

This study aims to create a smart pot that can automatically maintain indoor ornamental plants. This research begins with designing a pot model in a 3-dimensional image and fabricating using a 3D printer. The pot consists of 3 parts, namely the lower part for storage of the controller, the middle part as a place for nutrient water, and the upper part as a planting medium. Smart pots are equipped with sensors to support plant growth such as temperature and humidity sensors, soil moisture sensors, and water level sensors for plant nutritional needs. This system can be monitored and controlled remotely using an android smartphone if it is connected to Wi-Fi. The android application is made using MIT App Inventor which is connected to the firebase database so that it can be monitored via the internet remotely. Sensor data is sent in real-time and stored in the firebase database in the cloud. The test results show that the sensors in the pot are able to respond in real-time during the process of maintaining ornamental plants. The android application created can display indicators and the status of the plant microenvironment in more detail than the display on hardware.

Abstract

The lighting system is one of the aspects of assessing the function of the building. The building lighting system is included in the health aspect of the building. To achieve proper function, the building lighting system must meet the illumination value of each room according to the type of utilization in accordance with SNI 6197:2011, SNI 6197:2011, SNI 03-2396-2001, dan SNI 03-6575-2001. This study aims to analyze the lighting system in the Gedung Kuliah Bersama at the Politeknik Negeri Cilacap. This study uses a quantitative method by comparing the amount of light intensity based on field measurements, calculation results, and the SNI 6197:2011 standard. Based on the results of observations, data processing, and measurements, it was found that there were still some rooms in the Gedung Kuliah Bersama that did not meet SNI. Rooms that have fulfilled SNI include classrooms, library rooms, language laboratories, lecturer transit rooms, multipurpose rooms, terrace, and warehouses. It is necessary to carry out maintenance and repair of lamps for rooms that do not meet SNI. Maintenance and repair of lighting systems are carried out by replacing, adding, and/or repositioning lamps.

Abstract

Penggunaan terapi cairan intravena membutuhkan pengawasan yang ketat. Oleh sebab itu, proses penggantian cairan intravena yang telah mencapai batas minimum harus dilakukan secara tepat dan cepat, sehingga tidak mengakibatkan keterlambatan penggantian cairan intravena. Rentang rata-rata suhu normal pada tempat pengukuran suhu aksila adalah 34,7-37,3°C. Suhu tubuh yang meningkat dari rentang suhu normal disebut demam, yang mana harus memerlukan penanganan cepat dan selalu terpantau perubahan suhunya. Sistem ini menggunakan dua Panel Monitoring Pasien dan satu Panel Monitoring Perawat yang masing-masing menggunakan Arduino Mega 2560 sebagai mikrokontrolernya, sensor suhu DS18B20 dan sensor load cell, serta NRF24L01+ sebagai modul komunikasi nirkabel. Masing-masing panel monitoring terdapat LED sebagai indikator saat suhu tubuh pasien melebihi 37,3°C dan volume cairan intravena dibawah 30ml. Sensor load cell membaca nilai volume dengan akurat, sedangkan sensor suhu DS18B20 memiliki persentase error sebesar 0,47-0,52%. Panel monitoring pasien dapat memonitoring secara real time dan mengirim data suhu, dan volume cairan intravena pasien ke panel monitoring perawat. Panel monitoring perawat dilengkapi dengan buzzer untuk alarm setiap pukul 08.00, 12.00, 17.00 dan 21.00 serta LED indikator volume dan suhu. Komunikasi nirkabel antara node sensor dengan node master dapat berkomunikasi dengan optimal pada rentang jarak 1 sampai 12 meter dengan dinding tembok sebagai penghalang.

Abstract

— Indonesia masih menghadapi masalah dalam pembangunan bidang energi. Ketergantungan terhadap energi fosil bisa dibilang masih cukup tinggi. Pemanfaatan energi terbarukan dapat dikatakan belum berjalan sebagaimana mestinya. Salah satu upaya yang dapat dilakukan yaitu dengan energi alternatif. Pembangkit listrik dari kayuhan pedal sepeda statis dapat menjadi salah satu energi alternatif yang dapat membangkitkan energi listrik sederhan. Penelitian ini bertujuan membuat sepeda statis sebagai pembangkit listrik sederhana untuk keperluan perangkat elektronik sederhana. Alat ini bekerja dari kayuhan sepeda untuk memutar generator DC yang kemudian disalurkan pada SCC. Hasil tegangan listrik disimpan ke akumulator dengan watt meter sebagai indicator tegangan dan arus keluaran generator. Penelitian ini didapatkan RPM minimal untuk menyalakan watt meter pada RPM 50 pada kayuhan sepeda yang menghasilkan tegangan 6,09V. RPM maksimal pada 85 RPM dengan tegangan 13,61V, dimana akumulator akan terisi pada saat tegangan sudah lebih dari 12V.

Abstract

This study intended to create a sea wave simulator to find out the potential of ocean wave power plants. To achieve the objective, this study used two systems: generation and reading. Generation used a DC motor as a drive from sea waves, while readings employed an IMU-GY86 sensor for readings of altitude and energy potential generated. The result of this study is that air and air pressure affect the results of measuring the wave height of seawater. Air pressure is inversely proportional to the elevation of a place: the higher the area, the lower the air pressure. The highest potential energy density of seawater waves amounts to 2405.33 J/m2, and the lowest was 550.18 J/m2, with an average value of seawater wave density energy of 1342.41 J/m2.
