So that the fulfillment of vegetables needs to be increased by applying new methods of growing vegetables. One method that is successful in meeting the needs of vegetables is to apply a hydroponic system. The hydroponic system is a vegetable growing medium using water as a nutrient intake. Here apply the Nutrient Film Technique (NFT) hydroponic system, which is a hydroponic cultivation system with roots growing on a layer of nutrients continuously. The important thing in hydroponics is the fulfillment of nutrients in plants correctly. In this study, controlling pakcoy vegetables using fuzzy logic which can be monitored online using the Internet of things on a smartphone. The sensors used are TDS and ultrasonic sensors which are used as inputs, while the output given by the control of this system is the length of the pump opening. The pump is divided into three, the first is a pump for water, the second is a pump for nutrition A, and the last is a pump for nutrition B. In this system, nutrition control has been carried out on vegetable pakcoy using fuzzy logic control and can be monitored remotely using Blynk app on smartphones. This system can work well, which is able to maintain hydroponic vegetable nutrition in yanama pakcoy in the range of 900-1400 ppm.","PeriodicalId":31718,"journal":{"name":"Multitek Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41851836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of manually signing on paper is time-consuming and unsafe. In such places it is necessary to implement an efficient attendance monitoring system. The development of technology integrating technology in the fields of telecommunications, informatics, electronics and computers is known as Embedded System. One of the benefits that can be taken from the Embedded System is the Arduino IOT-based attendance monitoring system that is integrated with the MySql database. The tool is designed by combining the work of the Atmega328P microcontroller integrated with the Arduino uno with Radio Frequency Identification (RFID) The Tag has a unique code that is tapped on the RFID reader then the data sent by the ESP8266 wifi module is recorded in the MySql database to make it easier for users, an interface is made using LCD and Buzzer which will bring up information. This attendance monitoring system speeds up and simplifies the attendance process more accurately because the system is synchronized with the real time clock.

The aging process in a person is characterized by osteoporosis. Osteoporosis is a person's bone condition becomes porous and fragile. Marked by a decrease in bone tissue that is easily fragile or broken, a bent back and a shorter body. Alternative detection of osteoporosis can be done by X-ray image of the jaw bone from dental panoramik which analyzed the texture using machine learning and image processing techniques. Harris Corner Detection is a corner detection system that is often used because it is able to produce consistent values in images that experience rotation, scaling, variations in lighting and having lots of noise. Angular detection using the Harris method is based on variations in signal intensity. A large variation in intensity indicates the angle of the image. In the process of osteoporosis detection system using image processing, it is started from preprocessing, processing and final results.

Oleh karenanya, SMK berbasis IT menjadi sasaran dalam Teaching Factory. Berdasarkan data SMK yang ada di Kota Bogor maka perlu untuk dilakukan pengelompokkan terhadap bidang kejuruan yang akan menjadi landasan dalam sasaran. Adapun sebaran SMK menggunakan pendekatan teknologi SIG. Penelitian ini bertujuan untuk melakukan pemetaan sebaran SMK bidang Teknologi Informasi di Kota Bogor. Metode yang digunakan dalam penelitian ini adalah metode incremental. Adapun tahapan utama pada metode ini, yaitu analisis, design, code, testing. Berdasarkan hasil observasi, terdapat 15% sekolah negeri dan swasta telah berstatus melaksanakan teaching factory, namun masih terdapat sekolah yang belum melaksanakan teaching factory. Ada sekitar 50% SMK berbasis TIK di Kota Bogor, namun belum semua melaksanakan teaching factory, baru 8% SMK Negeri dan Swasta yang sudah melaksanakan teaching factori di bidang IT.

The Covid-19 pandemic has made many industries implement information and communication technology (ICT) to support work programs. In addition, this condition makes people have to learn quickly to use IT. Therefore, IT-based Vocational Schools are the targets in the Teaching Factory. Based on the data of SMK in Bogor City, it is necessary to group the vocational fields which will be the basis for the target. The distribution of SMK uses a GIS technology approach. This study aims to map the distribution of SMK in the field of Information Technology in the city of Bogor. The method used in this research is the incremental method. The main stages of this method are analysis, design, code, and testing. Based on observations, there are 15% of public and private schools have implemented a teaching factory, but there are still schools that have not implemented a teaching factory. There are around 50% of ICT-based SMKs in Bogor City, but not all of them have implemented teaching factories, only 8% of Public and Private Vocational Schools have implemented teaching factories in the IT field. This can be a target for industrial stakeholders to be able to work together with schools in carrying out teaching factories to revive the business sector after the COVID-19 pandemic. ","PeriodicalId":31718,"journal":{"name":"Multitek Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42755088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, during the dry season, many areas in Indonesia, especially coastal areas, are experiencing a water crisis. One alternative to solving this water crisis problem is the desalination method. Desalination is the process of purifying sea water into fresh water by heating it, so that it becomes a solution to the needs of clean water for the community. The purpose of this research is to design and make a desalination system from seawater to fresh water using a hybrid energy source from solar panels and conventional energy sources equipped with a data logger as a monitoring device. In this research, a renewable energy-based hybrid desalination system is designed. The desalination system uses a water evaporator as a component to support the seawater evaporation process and the use of a hybrid system by utilizing energy generated by solar panels and conventional energy. The use of data loggers can help provide an overview of the performance and efficiency of the seawater desalination system. From the test results that have been carried out, the water evaporator desalination system produces an average of 43 ml / hour of desalination water.
