Abstract

Utilization of industrial development 4.0 and IoT in the agricultural sector is still very minimal even though with the use of IoT technology and industrial development 4.0. in the agricultural sector can increase agricultural productivity. Efficiency in terms of watering plants manually is still lacking. The solution to this problem is to take advantage of technological developments, namely presenting a new innovation in watering plants by designing plant watering tools and monitoring using a web-based arduino Mega 2560 Rev3 microcontroller. The sensors to be used are: YL-69, DHT11 and HY-SRF-05 as the water tank volume sensor from the device, and using the ESP-01 as a WiFi module. If one of the earthen boxes is dry, the tool will water the dry soil box. This tool will also display the sensor data to the LCD screen, then send the sensor data to the database and the monitoring results will be presented in web form. The tool that has been designed can be used as a tool for watering plants for farmers and the general public as well as for up-to-date monitoring of plants.

Abstract

Control of population is one of the tasks of the government in Indonesia. The increase and movement of population in each region makes a certain area to defeat changes in population surging, and this can affect the economic level of the area. This study aims to process the population of Pematangsiantar City in 2018 which is divided into age groups, namely: Toddlers, Young Children, Early Adolescents, Late Adolescents, Early Adolescents, Late Adulthood, Early Adulthood, Elderly, Late Elderly, and Upper Seniors. Data processing is done by using K-Means method clustering in accordance with the population of Pematangsiantar City per district. With this grouping, we can see that the number of population in each sub-district is based on each age group so that we can implement programs that are more appropriate in improving human resources.

Abstract

Utilizing Computer Based Test (CBT) application at HKBP Hutabayuraja private high school can enhance the effectiveness of the student learning evaluation process by improving accuracy and objectivity, saving time and costs, and motivating students. However, the lack of knowledge among teachers and staff about CBT remains a major obstacle in implementing this technology. Hence, socializing and training teachers and staff is crucial to maximize the benefits of this technology, while also ensuring the protection of student data from unauthorized use. The CBT application provides flexibility in terms of time and place, as it can be accessed through a computer or mobile device, allowing students to carry out learning evaluations anytime and anywhere. To optimize its usage, adequate training and socialization for teachers and staff is necessary. The use of CBT applications offers numerous benefits for both teachers and students in the learning evaluation process, highlighting the need for broader implementation of technology such as CBT applications to increase efficiency and effectiveness in evaluating student learning.

Abstract

Expected Length of School is the length of school (in years) that is expected to be felt by children at a certain age in the future. It is assumed that the probability that the child will remain in school at the following ages is the same as the probability of the population attending school per total population for the current age. Length of School is also a benchmark for evaluating government programs in improving Human Resources who excel in the competition of technological advances. This writing is done to implement and prove that the Fletcher-Reeves Algorithm can be used to predict Old School Expectations in North Sumatra. The research data is School Expectancy in North Sumatra which consists of 10 districts/cities, which was obtained from the Central Statistics Agency of North Sumatra from 2010 to 2020. This study uses 5 architectural models, namely 9-10-1, 9-15-1, 9-20-1, 9-25-1 and 9-30-1. From the five architectural models used, the best architectural model is 9-10-1 with an MSE of 0.0130650400. Based on this best architectural model, it will be used to predict the Expectation of Long Schools in North Sumatra for the next 5 years, from 2021 to 2025.
