Abstract

The Mushroom is a wild plant and grow a lot in damp places, at the former rice bran and even grows on rotten trees. In the process of drying oyster mushroom it is very easy, only requires land for nurseries and maintains the temperature inside the oyster mushroom kumbung itself, for maintenance you must maintain the temperature and the humidity so that in the kumbung it remains moist and the oyster mushroom baglog not dry out because the temperature is not as required oyster mushroom baglog. So far, the cultivation that has been carried out is still manual, usually watering the oyster mushroom kumbung in the morning and evening, sometimes when it is hot during the day, watering is done to reduce the temperature inside the oyster mushroom kumbung. In this case the research was carried out on monitoring of temperature and humidity of oyster mushroom kumbung and automatic misting based on IoT which is combined with the blynk application which can be opened on an android smart phone by relying on an internert connection so that you can find out the temperature and humidity in the oyster mushroom kumbung This system uses a DHT11 sensor which functions to read temperature and humidity so that it sends data to NodeMCU V3 and then sends it to the user via the blynk application. If the temperature obtained is >30,200 the it will give a fog epek to the baglog automatically and the led in the blynk application will light up as a notification to the user that in the kumbung the oyster mushrooms are doing mist to lower the temperature of the kumbung and when the temperature is <=30.00 the fog will be stop and the led light in the blynk application will turn off, to be able to see the temperature and humidity of the oyster mushroom through the blynk application, you must first connect to the internet, both from the monitoring tool for oyster mushroom kumbung monitoring and automatic fogging based on iot or the smart phone user.

Abstract

Tujuan penelitian ini adalah untuk mempermudah guru dalam penyampaian materi kepada siswa dan meningkatkan pemahaman siswa terhadap materi yang disampaikan serta sebagai media untuk meningkatkan minat belajar dan kesenangan dalam proses belajar. Media pembelajaran memiliki peran penting dalam  proses belajar mengajar, namun kenyataan didunia pendidikan media pembelajaran sering diabaikan dengan alasan terbatasnya waktu untuk membuat persiapan mengajar dan sulit mencari media yang tepat. Di Kelompok Belajar Tarbiyatul Ummah Tanak Kaken menggunakan media pembelajaran yang masih bersifat konvensional dengan menggunakan buku, papan tulis dan alat peraga lainnya sebagai alat belajar siswa, media pembelajaran ini masih kurang menarik bagi siswa terutama dalam pelajaran pengenalan huruf-huruf abjad. Sekarang ini anak-anak lebih cenderung suka belajar menggunakan media yang berhungan dengan teknologi terutama anak-anak usia dini, dikarenakan lebih cepat menyerap pelajaran dari gambar-gambar menarik yang mendidik dan sesuai dengan usianya. Peneliti membuat media pembelajaran interaktif  berbasis Flash untuk lebih mudah mengenalkan huruf kepada siswa pendidikan anak usia dini pada Kelompok Belajar Tarbiyatul Ummah. Media pembelajaran ini dimulai dari proses analisis kebutuhan yang akan digunakan dalam pembuatan media pembelajaran interaktif dan membuat konsep atau perancangan sesuai dengan hasil analisis.DOI : 10.29408/jit.v3i2.2389

Abstract

East Lombok Regency is one of the second level regions in West Nusa Tenggara Province which is located on the east side of Lombok Island. The capital city of East Lombok Regency is the city of Selong, where all government agencies are based in this city. One of them is the Department of Environment and Hygiene of East Lombok Regency. In carrying out operational duties at the Office of Environment and Hygiene the operational vehicle requires that the fuel oil is a subsidy from the government. Therefore, the use of BBM every day must be recorded properly so that it can be predicted the amount of fuel usage every month. However, the Office of the Environment and Hygiene Office has difficulty in processing such data in large quantities. Predicted information on fuel use is needed by the head of the agency to assist in making decisions or policies. Of these problems the right data mining technique to use is classification. One method of classification of data mining is the decition tree algorithm (C4.5) or called the decision tree. The decition tree (C4.5) algorithm has weaknesses in reading large amounts of data, so researchers use weighting by applying Particle Swarm Optimization (PSO) for attribute selection to increase the accuracy of C4.5.Thus the researcher will utilize data mining software in applying a comparison of the decition tree (C4.5) and C4.5 algorithms based on Particle Swarm Optimization (PSO) to get the best accuracy value in predicting the amount of monthly use of fuel oil at the Service Office Environment and Cleanliness of East Lombok Regency.DOI : 10.29408/jit.v2i1.1173

Abstract

The application and use of technology today has been seen in almost every field of human life. This technology is here to help and facilitate humans in completing work and overcoming a variety of complex problems even for example in terms of analyzing as happened to the farmers and groups of oyster mushroom entrepreneurs in Dasan Borok Village, Suralaga District, East Lombok. The frequent occurrence of crop failure is a problem that currently occurs every time the harvest comes, this occurrence causes losses to farmers and must be dealt with quickly and appropriately. Web-based expert system is the right solution to overcome these problems, where this system can become an information center and be used as a tool in making decisions for farmers and entrepreneurs of oyster mushrooms to be able to determine the cause of damage and detect the types of diseases and pests that attack oyster mushrooms. With the implementation of this system it is expected to be able to overcome or reduce the problems of farmers to improve better and maximum yields.DOI : 10.29408/jit.v3i2.2316

Abstract

Along with the development of the human mindset, humans begandevelop systems that can help humans in overcoming problems that arise can be solved easily. Decision tree or better known as the decision tree is an implementation of the system that humans develop in finding and making decisions for these problems by comparing various kinds of problems related to these problems and related to education. Education is a conscious and planned effort to realize learning and the learning process so that students can increase the potential needed by themselves. The function of education is very important as one of the factors driving the development of human resources with the aim of increasing 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, the low quality of education is the result of the low quality of the learning process carried out in schools. On this occasion, the researcher made preparations for the grades of class XII students at SMK Negeri 1 Selong for 2018/2019 school year using RapidMiner as a tool and applying the Decision Tree method to assess student achievement levels as seen from the report card grades.
