Abstract

With current technological advances we can minimize or possibly prevent the effects of flooding by utilizing IoT (Internet of Things). On January 1, 2020 the volume of water in Cisadane overflowed which resulted in Panungnggang Barat Village being submerged by floods reaching 2.5 meters which had reached the roofs of houses, causing residents to flee their homes, look for medicines due to itching, and lose some of their assets. Panungnggang Barat Village currently does not have a tool to warn of flooding if at any time the Cisadane river overflows, therefore this research was made to make a flood early warning tool for residents to be vigilant if at any time the volume of water in the Cisadane river overflows into settlements. By focusing on research, observation, and interviews related to the matter being researched, researchers have observed and analyzed the problems in the Panungnggang Barat Village that there are no flood early warning devices, so residents are only guessing when the flood will come. From the problems that have been described, the researcher aims to create a flood early warning tool so that it can be useful for residents of Panungnggang Barat Village if at any time the water in the Cisadane River overflows, this tool will function as a warning to residents to be prepared for floods.

Abstract

The development of Internet of Things (IoT) technology has had a major impact on various aspects of life, including agriculture and plant care. This research aims to design a solution that can overcome the challenges of irrigating ornamental plants by utilizing soil moisture sensors and IoT technology. The approach used in this study is Hardware Programming. This approach involves leveraging hardware and programming to design and implement an IoT-based automatic watering system for ornamental plants. In its implementation, the NodeMCU ESP8266 acts as the control center, while the soil moisture sensor is used to measure soil moisture levels, the DHT11 sensor is used to measure ambient temperature, and the ultrasonic sensor is used to measure the volume of water in the container. The data obtained from these sensors is integrated with the Blynk application. The test results show that the system is able to provide an accurate and fast response regarding soil moisture conditions, as well as making it easier for users to monitor watering through mobile devices. This research contributes to overcoming plant care challenges by utilizing IoT technology and integration with the Blynk platform. It is hoped that this solution will provide benefits, especially for Tangerang Express Park rangers, so that they can monitor plant conditions in real-time.

Abstract

The background of research is able to listed as How to design application Android based, How to implement the design of applications Creative Man, how to test applications based on Android Agile Scrum methods will be used to build this application. Scrum is a methode based on agile principles is focus on effective teamwork, incremental products, and iterating processes to achieve the end result. Scrum, according to Schwaber & Sutherland, is a framework that can handle complex and ever-changing problems. In addition, it is considered to have the ability to provide high-quality products that match the desires of innovative and productive users in MAN Creative's medium-sized business of building an sales system that can be accessed online rather than replacing it. The old system still using offline system. Plan of built new system hopefully can expand the market with android applications. Customers can easily get information about any product sold without having go to Man Creative store. With new online system, MAN Creative can easily provide information about any product, such as product name, price, etc. MAN Creative can be known by many people.. Analysis of sales transaction security issues. In order for more expeditions to be available in the future, couriers or expeditions must be present. In the process of product development, its appearance will be updated to provide more complete information, including new or additional types of products.

Abstract

The development of a web-based Decision Support System (DSS) using the Simple Additive Weighting (SAW) method to evaluate and select students eligible for assistance based on predetermined criteria has been successfully accomplished. The SAW method involves six assessment criteria: family members (0.1), parental employment status (0.15), residence status (0.1), monthly income (0.3), student absenteeism (0.15), and academic achievement (0.2). The primary aim of this DSS is to streamline the decision-making process for teachers and administrators at SDN Panunggangan 4. Employing this algorithm, the system automatically ranks students based on their highest scores to prioritize those deserving of assistance. The study was centered on 32 sixth-grade students. Moving forward, it is hoped that this application can be enhanced and implemented more extensively.

Abstract

The purpose of digitization is to make an institution or organization more effective and efficient in various aspects, one of which is attendance. Therefore, this research aims to design a digital attendance system using NodeMCU as the microcontroller and RFID (Radio Frequency Identification) as the sensor to read student ID cards, integrated with a web-based database. Currently, at PPKD (Pusat Pelatihan Kerja Daerah) Jakarta Pusat, the student attendance system still relies on conventional paper-based methods, which are ineffective, inefficient, and prone to errors. In addition to reducing paper usage, the design of this digital attendance system also aims to promote student discipline in attendance. The research employs the Research and Development (R&D) method, which aims to produce a specific product or enhance existing ones. The testing results demonstrate the successful transfer of student data from their ID cards (E-KTP) to the database via RFID sensors and NodeMCU microcontrollers. The system also displays this data on a web interface designed using PHP programming language. Overall, this research contributes to an effective and efficient attendance monitoring process for PIC (Person In Charge) at PPKD Central Jakarta
