Abstract

Hemoglobin is important part of red blood cell to transport oxygen and carbon dioxide. Hemoglobin concentration in the blood can be used as physical condition parameter. A low hemoglobin level is called anemia and high hemoglobin level is called polycythemia. WHO has determined the anemia cut off level of hemoglobin concentration based on age, sex, and condition (pregnant or not). Currently, accurate and reliable hemoglobin concentration measurement uses invasive methods such as cyanmethemoglobin  and  automated  hematology  analyzer.  But these methods are expensive, not real time, high infection risk, and need special techniques. Non-invasive methods offer a better alternative because it has low infection risk, instant result, and portable in size. This work developed a non-invasive hemoglobin measurement for anemia diagnosis based on optical spectroscopy. The system utilized LED and photodiode as optical sensor placed on the fingertip. Photodiode just could obtain DC component, so the signal conditioning circuit which consisted of HPF, LPF and amplifier was used to obtain the AC component of the signal.  This system used microcontroller to control the operation of the hardware and to calculate the hemoglobin concentration.Hemoglobin is important part of red blood cell to transport oxygen and carbon dioxide.

Abstract

Three wheeled omnidirectional robot has been used in industries and academics fields because its ability to move freely and simultaneously both rotation and translation. Free movement in this robot is assisted by omni wheel which consists of wheels and rollers. So, the movement of this robot is a combination of wheel and roller rotation. At present, the task given to the mobile robot is increasingly complex, so it makes microcontroller’s workload heavier. A microcontroller’s workload could be lightened by master-slave configuration to divide the microcontroller’s tasks. The wheel rotating speed control system uses a pid controller to obtain a fast and stable wheel speed response. The PID parameters, kp,ki,kd were obtained by using the hand tuning method. The testing results shown the average error of robot direction is 4,3750 and the direction of the robot’s face changed 5.750.

Abstract

ABSTRAKTanaman cabai rawit dapat tumbuh optimal pada kelembaban tanah 60%-80% dengan suhu udara rata-rata 18 – 30 derajat celcius. Penyiraman yang ada saat ini masih menggunakan sistem manual yang akan membuat kerugian dalam waktu dan tenaga. Selain itu penyiraman secara manual juga memboroskan air dan dapat membuat tanaman layu. Pada studi ini diusulkan sebuah sistem untuk membantu menjaga kelembaban tanaman cabai dengan menggunakan teknik irigasi tetes gravitasi yang dapat dipantau secara online dan realtime pada sebuah aplikasi android dan google spreadsheet. Hasil pengujian menunjukan bahwa sistem ini mampu menjaga kelembaban tanah pada nilai 60%-80% dengan volume air yang digunakan sebanyak 26,67 mililiter/menit. Hasil rata-rata seluruh pengujian akurasi sensor dan motor servo menghasilkan nilai yang cukup baik dengan ratarata error sebesar 1,96% dan akurasi sebesar 98,04%. Selanjutnya hasil pengujian QoS untuk delay masuk pada kategori bagus dengan rata-rata 177,99 ms dan packet loss masuk kategori sangat bagus dengan nilai sebesar 0,02%.Kata kunci: Irigasi Tetes, Kelembaban, IoT, Firebase, Spreadsheet ABSTRACTCayenne pepper plants can grow optimally at 60%-80% soil moisture with an average air temperature of 18 – 30 degree celcius. The current watering still uses a manual system which will result in a loss of time and effort. In addition, manual watering also wastes water and can make plants wither. In this study, a system is proposed to help maintain the humidity of chili plants by using gravity drip irrigation techniques that can be monitored online and in real time on an android application and google spreadsheet. The test results show that this system is able to maintain soil moisture at a value of 60%-80% with the volume of water used as much as 26.67 milliliters/minute. The average results of all sensor and servo motor accuracy tests produce a fairly good value with an average error of 1.96% and an accuracy of 98.04%. Furthermore, the QoS test results for delay are in the good category with an average of 177.99 ms and packet loss is in the very good category with a value of 0.02%.Keywords: Drip Irrigation, Humidity, IoT, Firebase, Spreadsheet

Abstract

The pandemic has caused a shift in the tourism industry's drive towards comprehensive digitization. This approach is used to prevent the spread of the Covid-19 virus. The impact of Pemberlakuan Pembatasan Kegiatan Masyarakat (PPKM) limiting the mobility of tourists who will vacation in Indonesia causes losses and foreign exchange earnings of the state in the tourism industry sector of 20.7 billion. So, to survive in the current situation, industry players must be able to adapt and rise by providing more effective innovations. This study aims to develop a Question Answering System or a digital question and answer system using a chatbot (ChatterBot). The chatbot is used as an information service provider that can make it easier for tourists who are looking for information about tourist attractions. Chatbot-based information service systems can work 24 hours or all day, reducing the intensity of direct physical contact with officers and saving operational costs. The chatbot implementation is built on the Machine Learning Framework using RASA Open Source with the Python programming language. The knowledge base of the chatbot system is trained based on the FAQ (Frequently Asking Question) dataset with a case study of the Prambanan Temple tourist attraction as a sample of Indonesian tourism. The results of the evaluation and system performance based on data testing obtained the level of model accuracy is 0.91. Furthermore, the weighted average value in the Confusion Matrix produces a precision of 0.97, a recall of 0.94, and an F1-score of 0.95. The training and testing model processes locally using the Visual Studio Code software.

Abstract

Ikan Maskoki merupakan ikan hias air tawar yang populer untuk dibudidayakan di akuarium. Populasi pembididaya ikan Maskoki diproyeksikan akan mencapai 129.734 ribu ekor pada tahun 2024. Pemeliharaan ikan maskoki membutuhkan suhu air berkisar 25,7 – 29,7°C, kekeruhan mininum 10 NTU, dan pH air berkisar 7,1 – 7,6. Pemberian pakan yang tidak tepat dapat mempengaruhi pertumbuhan dan membahayakan keadaan ikan. Dengan adanya teknologi Internet of Things (IoT) dan Network Time Protocol (NTP) dapat merubah kegiatan pemberian pakan secara manual menjadi otomatis pada waktu tertentu tanpa tambahan perangkat. NTP merupakan protokol internet yang digunakan untuk melakukan sinkronisasi waktu pada jaringan komputer. Penelitian ini diharapkan dapat memantau parameter akuairum dan penjadwalan pemberian pakan secara otomatis. Hasil pengujian keseluruhan sistem untuk berjalan dengan baik, sistem bekerja sesuai jadwal yaitu pukul 9:00 dan 17:00. Hasil pengujian sensor suhu memiliki nilai persentase galat sebesar 1,17% dan nilai akurasi sebesar 98,83%. Hasil pengujian sensor pH pada derajat keasaman 7 memiliki nilai persentase galat sebesar 1,39% dan nilai akurasi sebesar 98,61%. Hasil pengujian sensor kekeruhan air menunjukkan mampu memberikan perubahan kekeruhan air saat pemberian pakan. Hasil data menunjukkan bahwa sistem sensor telah sesuai untuk diaplikasikan pada budidaya ikan Maskoki. Sistem penjadwalan berbasis NTP juga mampu menjadwalkan pemberian pakan sesuai dengan scenario yang diinginkan.
