Abstract

he research was conducted on the pig farm owned by Mr. Santo, at the West Bandulan, Sukun Sub District of Malang in East Java province for 4 weeks (1 month). This research uses 4 pigs where 2 tails are fed automatically and the 2 tail still uses manual way. The purpose of this research is to provide farmers with information on the effects of feeding timely on the increase in pig weight. The method used is the experiment (experimental) consisting of 2 experiments that were first performed automatic feeding of 2 pigs that both feed manually against 2 pigs so as to find a comparison of The experiment. Looking at this, then the author devised a tool scheduling and automatic feeding of Arduino-based Mega 2560. With this tool, the author hopes to help pig farmers in increasing pig weights and relieve breeder's work. Thereby can improve the welfare of pig farmers. Results of the experiment showed the growth of pigs using the automated system better with the result 0.58 – 0.68 kg per day.

Abstract

Merdeka Belajar Kampus Merdeka (MBKM) was established through Permendikbud No. 3 of 2020 concerning National Standards for Higher Education (SN-Dikti). MBKM brings significant changes, where universities must make adjustments to these changes. The success of the implementation of MBKM in higher education is measured using 8 Key Performance Indicators (IKU). One of the 9 BKP that is quite interesting is the National Defense activity or Komponen Cadangan (Komcad). Currently, the Ministry of Defense is preparing derivative regulations from the RI Law Number 23 of 2019 concerning the Management of National Resources for National Defense relating to the formation of Reserve Components. Discipline and Honesty. Student motivation directly influences Interest in Enrolling in the MBKM: Komcad Program, meaning that each student's motivation greatly encourages student interest in enrolling in the MBKM: Komcad program. Indirectly, discipline through Student Motivation has a significant influence on Interest in Enrolling in the MBKM: Komcad Program, meaning that Interest in Enrolling in the MBKM: Komcad Program is strongly influenced by the discipline and motivation of the students themselves.

Abstract

Penelitian ini merancang dan merakit alat sterilisasi yang disertai pengukur suhu tubuh dengan tujuan membantu pemerintah dalam pencegahan tersebarnya virus Covid-19 dengan cara memutus rantai penyebaran virus tersebut. Penelitian ini menggunakan Metode SISO fuzzy untuk menentukan pengaturan timer pada saat penyemprotan. Suhu tubuh normal manusia adalah 35⁰C–37,5⁰C, namun ketika tubuh bereaksi terhadap benda asing yang masuk ke tubuh dan bersifat menginfeksi, maka suhu tubuh akan beadaptasi dan naik diatas 37,5⁰C. Ketika suhu tubuh diatas 37,5⁰C, alat akan mendeteksi sehingga otomatis melakukan tindakan yaitu bunyi alarm yang menandakan bahwa suhu tubuh melebihi batas normal sehingga perlu diwaspadai dan ditindak sesuai prosedur deteksi COVID-19. Lama penyemprotan didasarkan pada kondisi objek, jika suhu tubuh diatas 37,5⁰C maka penyemprotan otomatis berlangsung selama 60 second dan jika suhu tubuh objek normal maka penyemprotan berlangsung selama 30 second.

Abstract

The farming profession in the industrial era 4.0 is considered ancient and has no potential and bonafide. To change such a mindset, Community Service (PKM-Unmer Building Village) in collaboration with hydroganic farmer groups to make greenhouse and hydro-gas models accompanied by water flow monitoring (flow sensor), temperature, and humidity monitoring (DHT11 sensor) and electricity control (UPS). By utilizing the IoT concept in a monitoring tool that is placed in hydroganics, it can monitor the flow of water and plants in real-time. To access monitoring, the cellphone must be connected to the same wifi as the device, then enter the IP address using a mobile browser. The method of implementation used consists of three stages: preparation includes a review of partner locations, coordination, and the number of partners and existing facilities, pilot and, socialization. The results obtained from this activity are to accelerate and make it easier to control the hydroganics contained in the greenhouse in real-time. By utilizing a UPS to make the water pump always on, the equipment is not easily damaged if there is an electrical disturbance such as a blackout or short circuit. PKM-Unmer Building Village produces a pilot modeled in a greenhouse, socialization to the community and Bengkel Mimpi farmer groups, and training to make simple monitoring tools.

Abstract

In Indonesia Rosella Flowers are used as herbal tea. The process of brewing Rosella Tea is brew 3 – 4 dried rosella petals with 200ml hot water. This brewing process takes a long time from 10 minute or 15 minute. One of way to improved is crushing the rosella flower to little shape with apply PID method. This machine use Atmega32 as controller, speed sensor, laser sensor, and DC Motor as actuator. The working principle of this machine is to stabilize DC motor speed, effective procces is at 900 RPM, in this speed takes 07 minutes 15 seconds to finished the process, and laser sensor has not detected rosella flower to crushing the system will turn off automatically. With percentage overshoot  10.2 %,  settling time 245 seconds, and biggest error of speed sensor is 2.6 % . The reuslt from speed sensor will display at LCD 2*16 to make easily to analysis.

Abstract

Menara Base Transceiver Station (BTS) is a telecommunications station whose main function is to facilitate wireless communication between communication devices (clients) and network operators. BTS towers are usually built in densely populated residential areas, due to distributing telecommunications networks. Because it was built in a densely populated settlement, it is necessary to pay attention to the feasibility maintenance of the BTS tower. BTS tower maintenance is intended so that BTS towers can work optimally and reduce the risk of collapsing. The prototype will be made with several components, namely the MPU-6050 sensor, Arduino Uno and LCD. MPU-6050 to detect the tilt of the BTS tower. After 10 tests of pitch and roll angles, the prototype of the BTS tilt has an average error of 1.077 for pitch angle and 1.703 for roll angle. These results are still valid in monitoring the angle of inclination of the BTS

Abstract

The COVID-19 pandemic has significantly impacted Indonesia, necessitating a deeper understanding of public sentiment towards the crisis. This study investigates the performance of three prominent machine learning models: Bernoulli Naïve Bayes, Support Vector Machine (SVM), and Logistic Regression, in analyzing sentiments related to COVID-19 in Indonesia. Utilizing a dataset comprising social media posts, the research aims to classify sentiments into positive, and negative categories, providing insights into the public's perception of the pandemic and associated measures. Sentiment analysis serves as a powerful tool to capture the collective emotions and opinions of the populace, which are pivotal in shaping public health responses and policies. The accuracy of LR and SVM is 99%, whereas Bayesian has an accuracy of 98%. We conclude that Logistic Regression and Support Vector Machine are the best model for the above dataset. This research evaluates these models' accuracy and reliability in the context of the Indonesian language, which influence sentiment interpretation. The findings of this study will contribute to the fields of natural language processing and public health by highlighting the efficacy of machine learning models in sentiment analysis during a health crisis. Moreover, the results will assist policymakers and health officials in understanding public sentiment, enabling them to tailor communication and interventions more effectively.
