Abstract

Indonesian rice shops carry out the weighing process manually and in-a-hurry, so that it often makes the weighing incorrect. The built vending device can work automatically in weighing rice. It can weigh 2 types of rice and sold per kilogram. It consists of a processor module, input module, output valve drive module, indicator module and limit switch module. The processing module uses Arduino Nano; input module uses a push button that is used to select the type of rice. The output valve drive module uses a servo motor that functions to move the output channel valve so that the rice can come out of the container. The indicator module uses a buzzer that functions to provide information if there is little rice left in the storage tank. The limit switch module functions to detect rice cans on the rice output valve and functions as a reset button. If there is little rice left in the storage can, it is necessary to replenish the rice stock. The outgoing rice storage can has a capacity of one kg of rice. The built automatic system can increase efficiency in selling rice and productivity of the seller. The designed device does not use weight sensors or scales, however it has a difference in rice weight that is no more than 15 grams.

Abstract

With more than 300,000 members, Indonesia's military forces, consisting of the army, navy and air force, have a large need for electricity. A reliable and safe electricity source is a must. Especially in carrying out the task of defending the country in conditions that are critical and threaten the security of the country. For this reason, the use of microgrids can be a solution for energy independence. In addition, using microgrids consisting of renewable energy sources helps the government increase the renewable energy share. This research discusses the design and application of microgrids in the military. The study case is done in one of military facility in Indonesia. The first step is to identify the type of the system if it is on grid or off grid, then calculate the load, source of energy and decide the control system. In this study case where the load is 3082 kWh/day, it require 860pcs PV of 320Wp capacity with cycle charging controller systems and Diesel Generator with capacity of 260kW. It is hoped that it can be a guide for the military in Indonesia in implementing microgrids.

Abstract

Big city like Jakarta produce large volumes of waste so that it becomes a problem for their dumps. If waste is sorted according to its type, it can be recycled to produce a useful product that can reduce the burden on landfills. Waste sorting can be done in households and in public places. Many public places have provided trash cans to facilitate sorting,  organic, inorganic, and metal waste. However, many people ignore garbage disposal bin that are suitable for their type. In public places where many people gather,  the trash can fill up quickly so that if the garbage picker has not thrown it away, the garbage can accumulate and overflow out. A system is needed that can sort of waste disposal according to its type so that the waste recycling process becomes efficient and a waste disposal system that implements information technology to overcome the accumulation of waste quickly. The system proposed in this study can sort the type of organic or inorganic waste and also make it easier for garbage pickers to know when to pick up garbage through a notification from a smartphone. To find out the type, the garbage was scanned using proximity sensors and infrared sensors. The trash can will open according to the type of garbage detected. The ultrasonic sensor measures the height of the garbage connected to the NodeMCU microcontroller as a data processor. Waste height data is sent through the internet network and displayed on the Blynk application. Based on the test results, the system has succeeded in distinguishing three types of waste, namely organic, inorganic, and metal waste. Based on the results of the garbage height test, it is known that the system has successfully provided a notification on the Blynk application if the garbage can is filled to 80% high.

Abstract

Security systems are essential to prevent theft or other criminal acts in order to prevent the increase in theft crime rates from year to year. To overcome these challenges, this research designs a system that is integrated with a website, aiming to monitor the availability of lockers, perform the booking process, and open and lock lockers using Near Field Communication (NFC) cards. The purpose of this research is to review and analyze the application of NFC in locker design. The research conducted a literature evaluation that included 19 studies from scientific journals. The findings suggest that there are many research trends, methods, and architectures used in predictive analytics with IoT in the context of locker usage. Keywords: Security, Smart Locker, NFC, Internet of Things
