Abstract

Untuk mencegah penyebaran infeksi dan kuman pada saat kegiatan makan, mencuci tangan merupakan hal yang paling direkomendasikan. Untuk meningkatkan kesadaran masyarakat, Pemerintah telah mencanangkan dan memberikan panduan dan tatacara yang benar dalam proses cuci tangan. Pada penelitian ini untuk mempermudah kegiatan cuci tangan dan mengirit air, dibuat sebuah mesin pencuci tangan otomatis. Alat ini dirancang menitik beratkan pada kebersihan dan kehigienisan tangan pada saat mencuci tangan. Mesin ini terdiri dari 3 bagian yaitu kran air otomatis, kran sabun otomatis, dan pengering otomatis. Kran air otomatis terbuka saat mendeteksi adanya tangan menggunakan sensor ultrasonik dan kamera dengan deteksi bentuk tangan dan jarak tangan 20 kurang dari tangan kurang dari 30 cm. Selanjutnya kran sabun akan terbuka otomatis jika mendeteksi jarak tangan 10 kurang dari tangan kurang dari 15 cm dan pengering otomatis jika menidentifikasi jarak tangan kurang dari 5 cm. Bentuk tangan dideteksi melalui kamera menggunakan Haar-Training dengan 50 posiitif dan 30 negatif image yang diterjemahkan dalam bentuk XML.Kata-kunci: kran air otomatis, kran sabun otomatis, pengering otomatis, haar-TrainingDesign of a Camera-Based Automatic and Hygienic Hand Washing MachineAbstractTo prevent the spread of infection and germs when eating, hand washing is the most recommended. To increase public awareness, the Government has launched and provided guidelines and correct procedures for handwashing. In this study to facilitate handwashing and water-saving activities, an automatic handwashing machine was made. This tool is designed to focus on cleanliness and hygiene of hands when washing hands. This machine consists of 3 parts, namely automatic water faucets, automatic soap faucets, and automatic dryers. The water faucet automatically opens when it detects a hand using an ultrasonic sensor and a camera with hand shape detection and a hand distance of 20 less than hand less than 30 cm. Furthermore, the soap faucet will open automatically if it detects 10 less than a hand less than15 cm hand distance and automatic dryer if it identifies less than 5 cm hand distance. The shape of the hand is detected through the camera using Haar-Training with 50 positives and 30 negative images translated in XML.Keywords: automatic water faucet, automatic soap faucet, automatic dryer, haar-Training

Abstract

Perancangan alat laju penguapan (evaporasi) air garam perlu memperhatikan aspek ergonomic guna kesesuaian alat dengan petani tambak sebagai pengguna. Salah satu pendekatan ergonomic yang digunakan dalam perancangan alat laju penguapan air garam yaitu metode bodyspace. Tujuan penelitian ini adalah agar perancangan alat laju penguapan sesuai dengan antropometri orang Madura berjenis kelamin pria selaku pengguna. Berdasarkan data antropometri orang Madura berjenis kelamin pria pada rentang usia 21-24 tahun, data dimensi tubuh yang digunakan terkait pendekatan bodyspace yaitu data D1,D2,D4,,D24,D25,D28,D29,D33 dan D34, dengan persentil sebesar 95%. Hasil penelitian menunjukkan dengan memperhatikan data dimensi pada D1,D2 dan D34 ketinggian alat minimum sebesar 123 cm tinggi maksimum sebesar 193 cm, data D33 panjang alat sebesar 56 cm, data D24 dan D25 lebar alat sebesar 54 cm, data D2 ketinggian LCD sebesar 81 cm, data D28,D29 panjang handle sebesar 11 cm, data D28,D29 dan D33 ukuran wadah diperoleh panjang 30 cm, lebar 30 cm dan tinggi 9 cm. Berdasarkan hasil yang diperoleh, maka diketahui bahwa perancangan alat laju penguapan perlu dibuat secara fleksibel sesuai dengan data dimensi Antropometri orang Madura sebagai penggunanya.Design of Salt Water Evaporation Tools using the Madurese BodyspaceAbstract The design of the evaporation rate for salt water needs to pay attention to ergonomic aspects for the suitability of the tool with the farmer farmer as the user. One ergonomic approach used in the design of the salt water evaporation rate tool is the bodyspace method. The purpose of this study is that the design of the evaporation rate tool is in accordance with the anthropometry of male Madurese as the user. Based on anthropometric data of male Madurese in the age range of 21-24 years, body dimension data used is related to the bodyspace approach namely data D1, D2, D4,, D24, D25, D28, D29, D33 and D34, with 95% percentile . The results showed by taking into account the dimension data on D1, D2 and D34 the minimum height of the tool is 123 cm, the maximum height is 193 cm, the D33 data is 56 cm, the D24 and D25 data is 54 cm, the D2 height is 81 cm , data D28, D29 handle length of 11 cm, data D28, D29 and D33 container size obtained length 30 cm, width 30 cm and height 9 cm. Based on the results obtained, it is known that the design of the evaporation rate tool needs to be made flexibly according to the Madurese Anthropometric dimension data as its user.Keywords: Design, salt water evaporation rate tool, ergonomics, anthropometry, bodyspace, workspace

Abstract

In general, children's growth is monitored through Posyandu activities. This Posyandu seeks to monitor the growth and development of children so they do not experience malnutrition or malnutrition. One of the main factors in the process of physical growth and development is nutrition. However, the problem facing Posyandu today is the infrastructure used, namely measurement tools that still use conventional tools. This certainly affects the efficiency of parents in monitoring the growth and development of children, therefore this study designed a nutritional detection system for infants. The working principle of this tool utilizes an ultrasonic sensor to determine the baby's length and a load cell sensor to determine the baby's weight. The data detected by the two sensors will be processed using the stm32 microcontroller. By using the nutritional z-score formula, it can be classified into several statuses based on child anthropometric standards. Processed data will be displayed on the LCD and then stored in the MySQL database to make it easier to read the measurement results. In this study the test was carried out 10 times with different respondents. The data obtained from testing the design tool is compared with the measurement results on conventional tools so that an error is obtained on the weight sensor (load cell) of 3.3% and a success rate of 96.7%, the average percentage error on the height sensor (ultrasonic ) of 0.3% and a success rate of 99.7%.
