Abstract

Abstrak ¾ Menanak nasi sudah menjadi aktivitas sehari-hari yang dilakukan sebagian besar masyarakat Indonesia. Nasi menjadi makanan pokok yang dikonsumsi sehari-hari hampir di sebagian wilayah Indonesia bahkan di wilayah Asia sekalipun. Hal itu disebabkan nasi menjadi sumber karbohidrat yang sangat baik bagi tubuh. Adanya rice cooker sudah menjadi alat yang selalu digunakan untuk menanak nasi di masa sekarang ini. Akan tetapi, terlepas dari kemudahan dalam menggunakan rice cooker muncul kekurangan dari alat tersebut. Pengguna harus menakar beras dan air secara langsung dan tepat takaran agar menghasilkan nasi yang baik. Keterbatasan tersebut membutuhkan kesediaan waktu dan tempat bagi pengguna rice cooker. Berdasarkan permasalahan tersebut dibutuhkan antarmuka aplikasi yang dapat mengontrol dan memantau suatu sistem penanak nasi yang dapat menakar beras dan air secara otomatis. Pengontrolan sistem menggunakan aplikasi android berbasis IoT. Aplikasi android akan dapat memberi perintah untuk memulai proses menanak nasi, memeriksa ketersediaan air dan beras, melihat riwayat memasak, serta mematikan atau menghidupkan rice cooker. Pemanfaatan konsep IoT dengan menyimpan data di web server menggunakan layanan web hosting memungkinkan aplikasi android dan sistem dapat mengirim dan menerima data melalui koneksi internet sehingga aplikasi android dapat memantau dan mengontrol sistem dari jarak jauh dan kapan selama sistem dan aplikasi terkoneksi ke internet. Adapun hasil dari tugas akhir ini adalah pembuatan antarmuka aplikasi penanak nasi yang dapat mengirimkan data banyak beras 2-9 cup dengan delay rata-rata keseluruhan adalah 235 ms dan data rate keseluruhan adalah 1,5 Kbps. Lalu rata-rata energi yang dibutuhkan saat sistem penanak nasi bekerja pada satu jam pertama adalah 0.08875 KWh dan pada dua jam pertama adalah 0.005375 KWh. Kata Kunci : Internet of Things, Android Studio, phpMyAdmin, Mikrokontroler Abstract ¾ Cooking rice has become a daily activity carried out by most Indonesian people. Rice is the most common staple food in Indonesia even in Asia. It becomes rice for a very good source for the body. The existence of a rice cooker has become a tool that is always used to cook rice today. However, in spite of the ease of using the rice cooker a shortcoming of the tool appeared. The user must conquer rice and water directly and precisely to make good rice. This limitation requires setting the time and place for rice cooker users. Based on this problem an interface application is needed that can control and use a rice cooker system that can measure rice and air automatically. The control system uses an IoT-based android application. The android application will be able to give commands to start the process of cooking rice, check air and rice, see cooking participation, and activate or start rice cookers. Using the IoT concept by storing data in a web server using a web hosting service that supports Android applications and systems can send and receive data through an internet connection so that the Android application can connect and control the system remotely and anytime using systems and applications connected to the internet. The final result of this final project is the creation of a rice cooker application interface that can send data of 2-9 cups of rice with an overall average delay of 235 ms and an overall data rate of 1.5 Kbps. Then the average energy needed when the rice cooker system works in the first hour is 0.08875 KWh and in the first two hours is 0.005375 KWh.

Abstract

Lung sound is one indicator of abnormalities in the lungs and respiratory tract. Research for automatic lung sound classification has become one of the interests for researchers because lung disease is one of the diseases with the most sufferers in the world. The use of lung sounds as a source of information because of the ease in data acquisition and auscultation is a standard method in examining pulmonary function. This study simulated the potential use of Higuchi fractal dimension (HFD) as a feature extraction method for lung sound classification. HFD calculations were run on a series of k values to generate some HFD values as features. According to the simulation results, the proposed method could produce an accuracy of up to 97.98% for five classes of lung sound data. The results also suggested that the shift in HFD values over the selection of a time interval k can be used for lung sound classification.

Abstract

Tirah baring merupakan suatu keadaan yang mengharuskan pasien beristirahat di tempat tidur, tidak bergerak secara aktif. Hal ini dikarenakan adanya penyakit/gangguan pada alat atau organ tubuh yang bersifat fisik atau mental dalam jangka waktu yang lama. Keadaan ini memberikan dampak negatif seperti adanya peningkatan suhu pada daerah yang bersentuhan langsung dengan alas tidur. Peningkatan suhu antara tubuh pasien dengan alas tidur dapat menyebabkan kulit pasien menjadi lebih merah, terjadinya pembengkakan, dan kulit lebih mudah terkelupas sehingga rentan terjadi infeksi. Penggunaan alas tidur biasa pada pasien tirah baring dapat menimbulkan dampak yang lebih buruk seperti terjadinya luka dekubitus. Luka dekubitus merupakan kerusakan jaringan, kerusakan struktur anatomis, dan fungsi kulit normal akibat tirah baring dalam waktu yang lama tanpa ada perubahan posisi tidur secara berkala. Untuk mengatasi masalah tersebut, direalisasikan suatu alat bantu yang dapat memantau dan menurunkan suhu antara tubuh pasien dengan alas tidur. Alat bantu ini bekerja secara otomatis ketika suhu antara tubuh pasien dengan alas tidur terdeteksi ? 33°C dan pendinginan akan mati secara otomatis ketika suhu antara tubuh pasien dengan alas tidur turun menjadi ? 30°C. Alat yang dirancang dapat mendinginkan permukaan kasur sehingga menurunkan suhu antara tubuh pasien dengan permukaan alas tidur, kenyamanan suhu alas tidur yang digunakan pasien pada iklim tropis yaitu sekitar 33°C - 35°C pada suhu ruangan sekitar 25°C - 27°C.

Abstract

Automated access control systems have been widely used in recent years due to their high accuracy and security. In this study, we present an intelligent and secure electronic gate based on facial recognition and vehicle number plate recognition. The system combines multimodal biometric technology with face recognition using the 'face_recognition' package and automatic licence plate recognition (ALPR) using YOLOv8 and PaddleOCR to enhance the security of access to restricted areas. The system was able to correctly recognise 29 out of 30 faces, while all licence plates were accurately recognised, even at different times. The results show that the automated gate system has been successfully developed and tested with an accuracy rate of 96.67%. This success demonstrates the potential use of multimodal biometric technology to improve the security and efficiency of access control systems in various applications, such as office environments, residential areas and other public facilities. Further research can be directed towards improving the resilience of the system to different environmental conditions and expanding the database of recognised faces and vehicle number plates.

Abstract

StuVent is an application designed to provide information on the health status of infants aged 0-24 months and to detect early stunting. This application displays the classification results of the infant's health status, differentiated by colour, making it easier for users to understand the infant's health status. StuVent is aimed at Posyandu's staff and the general public to help them detect early stunting. The main advantage of this application is its ability to work offline using Bluetooth Low Energy (BLE) connectivity. Users can connect their smartphones to the scales via Bluetooth, allowing the application to be used without an internet connection. This feature is particularly beneficial for users in 3T areas (frontier, outermost and remote regions) where internet access is often limited. StuVent is therefore expected to be an effective tool for monitoring child growth and preventing stunting in various regions.

Abstract

Rock resistivity properties obtained using the geo-electric method are used to estimate subsurface soil structures and rock types in geophysical exploration. The data collection process using this geoelectrical method is often carried out in remote areas by installing current electrodes (AB) and potential electrodes (MN) up to 1.5 km away. The success of exploration is highly dependent on the current injection source used. The greater the current used, the deeper exploration that can be carried out. However, the required distance between AB and MN electrodes is getting further and the ABMN electrodes are connected by a cable. This causes the process of collecting data at further distances of electrodes to become more complex. This study discusses a current source prototype for geo-electric methods that can communicate wirelessly with TTGO LoRa ESP32 as a controller. This prototype provides three injection power options: full, medium, and low. Current injection is carried out on a dummy resistor, which acts as earth. When injecting current into the dummy resistor, current measurements obtained using the INA219 sensor gave very consistent measurement results because it had a relative error of < 1% (on 50 ? and 300 ? dummy resistors). When measuring a current of 0.0066 A, the relative error increases to 1.5%. But it still shows good consistency in the INA219 measurement results. In addition, the MAPE for all measurements is within < 10%, which means that the INA219 readings provide excellent results. Key Words: current injector, geo-electrical, INA219, voltage divider, TTGO LoRa.

Abstract

Warjabakti Village has various agro-tourism potentials that have not been managed properly, namely in the form of a charming natural scenery, natural conditions that are still maintained, and cool air. The problems faced are the need for more exposure to technology, the unavailability of supporting facilities and infrastructure, and the absence of groups capable of coordinating these potentials. This community service aims to develop a community-based tourism system by integrating digital marketing technology to empower target communities. The results achieved from this community service activity are the formation of Pokdarwis, which have been legally approved by the village government and will oversee the management of the tourism village in Warjabakti Village with governance that the team and partners have made. In addition, the e-digital map and the Haruman Tourism Village website have been produced. This website contains village content and branding that displays attractive village information, videos, and animations that have been structured and integrated, as well as a complete and attractive e-digital map of tourist areas.
