Abstract

The world is suffering by the Covid-19 pandemic which all activities including the learning process is having trouble. Thus, the Indonesian government provides a solution is all the learning process should be at home. The teaching and learning process is carried out by online. The reduced interest in student learning becomes a problem that occurs during online learning, therefore teachers must create a lesson that can increase students interest and motivation in learning. One interesting learning application creator is is the Articulate Storyline. Articulate Storyline is an application for making learning tools. This research was made using the RnD method. This method includes initial analysis, product design and design, product manufacture to testing. In this study, the results obtained that the validity level was 83.80%, the practicality level was 92.24% and the effectiveness level was 96.47% so that the learning tools produced in this study could attract students' interest in learning in the pandemic era.

Abstract

Farming is the main source of livelihood of Indonesians living in rural areas, one of which is corn. Corn yields are influenced by many factors, among others, the ever-changing climate, water availability, soil fertility, crop management systems and so on. At the time of initial observation to the farmer group failure is often also experienced due to the disruption of pig pests at night. So that a system is needed that can control the handling of pig pests by making traps using a stun tool. To convert DC (Direct Current) current into AC (Alternating Current) can be done with a series of power transistors. The power transistor designed is using the flip-flop method, both transistors will work alternately, this type of change includes a phase changer. The goal in this study was to create a microcontroller-based garden fence control device. This tool is able to provide an alternative in making it easier for farmers to control the land so as to avoid pig pests. The results of the trial DC current changer to AC d field is very well functioning so that farmers no longer experience pig pest disturbances at night.

Abstract

Perkembangan sistem ketenagalistrikan semakin pesat sejalan dengan pengembangan  energi baru terbarukan. Intermittent menjadi masalah utama pembangkit listrik terbarukan, sehingga penggunaan baterai menjadi solusi. Namun hal ini justru menghasilkan limbah bahan beracun dan berbahaya sehingga tujuan untuk menciptakan energi bersih tidak dapat tercapai. Pengembangan  photovoltaic (PV) dengan sistem grid tied  dapat menjadi solusi dari masalah tersebut. Manfaat dari penggunanaan PV dengan sistem grid tied adalah konsumen dapat menyuplai daya di kondisi daya   berlebih dan digantikan pada malam hari sehingga ada pemotongan dari pembayaran listrik setiap bulannya. Dengan begitu, teknologi penyimpanan tidak lagi digunakan pada sistem ini dan terjadi dampak posisitif dari sisi ekonomi pada konsumen. Penelitian ini menganalisis aliran daya sebelum dan sesudah penggunaan PV pada beban home area network dan menghitung dampak ekonomi pada konsumen setelah menyuplai listrik pada grid utiliti.

Abstract

One of the animal movements is to jump, in addition to walking and crawling. Analyzing animal movements and routines is a time-consuming process and tends to be subjective, prone to errors due to the fatigue of the observer. The Tracker application is an open-source application used in video analysis and modelling tools to determine the accuracy of values. This study aims to analyze the differences in the movement of jumping frogs with different masses and lengths with the help of Tracker software which can use can use in independent practicum activities for science subjects with animal movements. The tools and materials needed include an Android cellphone camera, frogs, and the Tracker application. The measurement results are in the form of a graph of the frog's jumping motion. Furthermore, the data recorded in the Tracker is analyzed using Excel. From the research results, it can be said that tools that can be used in practicum and can track and analyze jumping movements are effectively used in analyzing changes in the x and y positions concerning time in daily learning applications so that they can be found around.

Abstract

Unit commitment is the scheduling of disconnected generation of generating units in an electric power system within a certain period, with the aim of meeting load demand. This scheduling is usually determined based on human load demand which always changes over time. This research aims to determine the production costs of thermal plants using the Second Order Gradient method to obtain economical operating costs, to determine fuel costs based on plant loading, and to determine the most economical scheduling using unit commitment. This is to determine the most optimal on/off schedule for generating units to be operated to meet the estimated load to achieve minimum fuel costs in rupiah.
