Abstract

PT. JNF is a company engaged in Engineering, Construction, and Project Management, located in South Jakarta. This company wants to develop its business by building housing in the city of Malang, to be precise in the Kedungkandang and Lowokwaru districts. The company needs some data and information about population density and land prices in the area to help the process of their project work. Providing information on data and forecasting results about population density and land prices in the area will help companies facilitate business development. Therefore, companies need an information system that can predict population density data and land prices in Kedungkandang sub-district and Lowokwaru sub-district, which functions to help companies see land business opportunities in Malang for housing development. The method used to make this system is the Double Exponential Smoothing method, because this method has a trend pattern that matches the data pattern of the object to be predicted. The data used are data from 2005 - 2018. The result of population density forecasting for Lowokwaru sub-district is 8713.98 and has a MAPE value of 1.39%, for Kedungkandang sub-district is 4949.07 and has a MAPE value of 2.55%, for the land price of Lowokwaru sub-district is 2777725.18 and has a MAPE value of 3.45 % and Kedungkandang sub-district is 1766560.27 and has a MAPE value of 8.36%. Based on the calculation of the MAPE value the results of the forecast above, it can be concluded that if the greater the constant value, the lower the MAPE value, the best constant value is between 0.6 - 0.9. The land business opportunity in Lowokwaru and Kedungkandang sub-districts is high based on the forecasting results of population density and land prices which tend to increase every year and the land business opportunity value based on ROI (Return of Investment) for the company is 0.38% of the initial capital. Keywords: information systems, forecasting, land business opportunities, land prices, population density, double exponential smoothing.

Abstract

Pengembangan teknologi IoT telah menjadi solusi yang menarik dalam bidang pertanian, terutama dalam konsep pertanian indoor. Pertanian indoor menawarkan alternatif yang ideal untuk menghadapi tantangan cuaca buruk dan perubahan iklim yang tidak dapat diprediksi. Namun, pertumbuhan tanaman dalam ruangan memiliki kelemahan terkait kondisi cahaya yang terbatas. Oleh karena itu, penelitian ini bertujuan untuk merancang perangkat IoT yang terintegrasi, melibatkan sensor soil moisture, sensor cahaya, UV LED grow lamps, dan pompa air, untuk memantau dan mengontrol kelembaban tanah, intensitas cahaya, serta memberikan pencahayaan tambahan yang optimal bagi pertumbuhan tanaman. Diharapkan penerapan teknologi IoT dalam pertanian ini dapat meningkatkan efisiensi penggunaan sumber daya, mengurangi dampak lingkungan, dan menghasilkan pertumbuhan tanaman yang optimal, sehingga mendorong pengembangan sistem pertanian yang lebih efisien, berkelanjutan, dan produktif.

Abstract

The use of electronic devices has become common in today's era, both in industries and in everyday life. However, the potential fire hazards posed by these devices, such as gas stoves and industrial equipment, need to be taken seriously. Despite the installation and maintenance measures taken to reduce risks, there are still other factors that can trigger fires. Therefore, it is important to develop a fire detection tool that can provide information about the room conditions so that appropriate preventive measures can be taken before or during a fire incident. By utilizing temperature and humidity sensors like DHT22, as well as smoke sensors like MQ2, a fire detection device can be designed. Through the use of these sensors and suitable programming, the system is capable of providing real-time room condition information and sending notifications when significant changes occur. The experimental results have shown that the system is responsive to changes in room conditions and capable of providing early warnings regarding potential fires.

Abstract

This research addresses the common problem in mathematics education in Indonesia, which is the students' difficulties, as reflected in Indonesia's declining ranking in the Program for International Student Assessment (PISA). The research aims to create an innovative Augmented Reality (AR) Educational Game based on the Realistic Mathematics Education (RME) approach to improve students' understanding of the spatial geometry mathematics subject at the elementary school level. AR technology allows students to interact with mathematical objects in real-world contexts using Android devices. This game is designed to make mathematics more engaging and relevant to elementary school students. The research was conducted at Purwantoro 1 Public Elementary School in Malang City over four months, following the Game Development Lifecycle (GDLC). The test results showed an n-gain improvement of 0.71, indicating a positive impact of the game's development on students' learning outcomes.

Abstract

The widespread use of Telegram in Indonesia has had both positive and negative effects. While the app offers strong security features, it has also become a platform for digital crimes, including sexual harassment. This study aims to address the need for effective forensic analysis and classification methods by employing the National Institute of Justice (NIJ) methodology and Naïve Bayes classifier to analyze conversations on Telegram. The research evaluates the performance of digital forensic tools and the effectiveness of the Naïve Bayes method in identifying instances of sexual harassment conversation. The data analyzed is about conversations on the telegram application that contain sexual harassment. Data collection involves extracting relevant conversations and subjecting them to forensic analysis using MOBIL edit Forensic Express and FTK Imager. Based on the test results, the naïve Bayes algorithm can be used to classify conversations into positive and negative about sexual harassment. The value obtained from naïve Bayes testing is the accuracy value of 91.3%, Precision 100%, and Recall 90%.

Abstract

Fires can cause material losses and human lives. Therefore, an effective fire early detection system is needed to prevent greater losses. In this research, ESP8266 is used as a microcontroller to connect fire detection sensors such as KY-026 Fire Sensor and MQ-2 Smoke Sensor. This early fire detection system is also equipped with a buzzer as an alarm and NodeMCU as a platform to connect the system to the Internet network and Blynk as a medium to provide real-time fire notifications to users. Tests were conducted by comparing the response time and accuracy of fire detection at different distances. The test results show that the fire early detection system built has an average response time of 2 seconds and a detection accuracy rate of 95%.

Abstract

Students frequently encounter difficulties in describing complex problems as simple ones, analyzing the general differences and similarities of a problem, and generalizing problem solving patterns based on computational thinking. One solution to these issues is to use the concept of gamification on the learning platform. Which aims to develop a computational thinking learning gamification website. The gamification website developed applies gamification elements in CT learning such as implementing points where each level of difficulty level has a different point. Implements 3 levels namely “siaga”, “penegak”, and “penggalang” by applying the level the user can find out the level of difficulty of the questions according to the level provided such as. Then when working on the questions, you will get a badge that aims to symbolize the extent of the user's ability level when finished working on the questions. And the last one implements a Leaderboard which displays the user's overall rating. Users find the website for Computational Thinking Gamification to be satisfying as well as functional, according to the average score of 87 percent that it received from twenty different participants.
