Along with the development of the human mindset progress, humans began to develop a system that can help humans in dealing with problems that arise so that they can solve them easily. The decision tree or better known as the decision tree is an implementation of a system that humans develop in finding and making decisions for these problems by taking into account the various factors that are related within the scope of the problem and among about education. Education is a conscious and planned effort to create an atmosphere of learning and learning process so that students can increase their potential. The function of education is very important as one of the factors driving development as human resources to increase the ability of the community to develop science. Thus, the teaching and learning process is one of the determining factors for the success of education in schools/madrasas, the low quality of education is a result of the low quality of the learning process carried out in school

Malnutrition or Malnutrition is a general term that refers to a medical condition caused by an improper or inadequate diet. The main cause of malnutrition is the lack of children in getting enough energy and protein foods. This is with the economic level of the community. In addition, for parents' knowledge about the importance of nutrition for child development. In East Lombok, cases of malnutrition always appear every year, but recently in 2019, cases of malnutrition were rediscovered which ironically was always known too late. This is because the location of malnutrition sufferers is not reachable or is not known by the district government, this is what makes the handling of malnutrition cases in East Lombok district late, which often results in deaths of infants and children. For this reason, in this study the researcher raised the theme of how to map the distribution of the location of well-known cases of malnutrition in East Lombok district. The purpose of this study was to help the East Lombok fogapen government to see the location of people with malnutrition. The research method used is to directly record the coordinates of the location of people with bad nutrition. with this application, it can help the government in alerting the location of cases of malnutrition in East Lombok district

Water is a source of life that is needed by living things. Many people have switched to using PDAM water to fulfill their daily water needs so in the distribution process the PDAM requires a process of checking or recording by officials the amount of water used that is distributed to each customer. This raises a problem, namely that there is often a discrepancy between the amount of water used and the fees that must be paid and the water meters used by the PDAM are still analog in nature so the water usage data is difficult for customers to know. This is one of the factors causing the soaring bills of fees that must be paid for water needs to the PDAM every month which often results in several possibilities, namely non-payment, leaks, or fraud. So we need a tool to facilitate the PDAM and PDAM water customers in monitoring water use as well as the amount of payment. The tool is in the form of a PDAM Water Usage Monitoring System Design using Internet of Things technology using a water flow sensor that will detect the use of water used, RTC to determine a date and time in the BLYNK application display, processed via the ESP32 Node MCU and displayed on the LCD as the output of current usage and bills to be paid. The processed data results will be sent to the BLYNK web server and can be viewed through the BLYNK application on an Android smartphone. The error value from the reading of the water flow sensor is 1%, which means the accuracy level is 99%. Meanwhile, the data from the reading of the system for calculating the cost of using PDAM water does not contain errors so the accuracy of the data reaches 100%.

Fashion dan furniture menjadi kebutuhan untuk setiap individu. Pemilihan fashion terkadang juga bisa menjadi penilaian orang lain terhadap karakter yang dimiliki tiap individu. Begitupun pemilihan furniture juga bisa menggambarkan identitas dari tiap individu. Namun fashion dan furniture memiliki berbagai macam model, untuk itu dibutuhkan teknologi informasi yang bisa membedakan antara model a dan model b. Klasifikasi adalah salah satu model yang mengelompokkan berdasarkan kriteria yang sama. Penggunaan klasifikasi haruslah didukung dengan metode yang tepat dan penggunaan epoch agar akurasi yang dihasilkan dapat maksimal. Metode Convolutional Neural Network (CNN) adalah metode yang sangat tepat untuk klasifikasi gambar karena terdapat banyak arsitektur yang bisa digunakan.Hasil penelitian ini menunjukkan bahwa akurasi terbaik pada furniture=94.18% dengan penggunaan epoch=500, dan fashion =99.15% dengan penggunaan epoch=1500

Tobacco is planted by the farmers in dry season through some process such as seeding, planting and drying. In drying process, the farmers use traditional technology named oven. When checking the temperature conditions of the tobacco, the farmers still use an estimation to measure the heat temperature of combustion stove. Base on those problems, the farmer need innovation technology which is used to make them easier to keep the stability of the temperature in the oven area in order to protect the quality of tobacco. “Internet of things” (IOTs) is provided to answer the farmers’ problem. By utilizing the internet of things (IOTs) in a Smartphone, this application will make the farmers easier to check the temperature conditions automatically to the temperature rises excessively without standing by in the oven or burning location. The application of IOTS with the data accuracy rate of ± 96%,%, can be said that it works well, although there are still shortcomings in the targets planned but the development program will be added. Hopefully, this application will help the farmer to be more ready to face 4.0 industry in the field of agriculture.
