Abstract

A dispenser is a household appliance that is used by almost every Indonesian citizen, a dispenser is a household appliance that functions as a container for gallons of water to refill. Because water is a very promising need, the water refill gallon business is very rapidly developing, both water depot owners or consumers sometimes cannot know when the gallon water runs out unless they see it directly, sometimes due to dense activity so they cannot monitor repeatedly when the water is gallon. it ran out so research was carried out on the manufacture of automatic dispensers. To carry out the automation process, it is assisted by a microcontroller device called Wemos D1, besides that there are two sensors as sending messages, namely the ultrasonic sensor and the infrared tcrt 5500 sensor with the help of an Android-based application so that water notifications run out on the smartphone. In addition, to calculate the messages sent through the sensor, the fuzzy logic method is used. After testing in this study, the ultrasonic sensor sends a message for water conditions in gallons and has a vulnerable value (0 - 40) 0 is a full gallon and 40 is an exhausted gallon. While the infrared tcrt 5500 sensor sends a message for gallon conditions and has a vulnerable value (100-1000) 100 is the value of gallons installed (GTS) and 1000 is the value of gallons not installed (GTT), it can be concluded that the applied method can determine the water condition used up and the condition of the gallon that is not installed and the accuracy obtained is 98%.

Abstract

Abstract: The government has continued to work hard in efforts to prevent the COVID-19 virus with complete vaccines for the community due to the importance of complete vaccination as an aspect of consideration for the implementation of the policy of doing activities without masks. Currently, only 15.91 percent of Indonesia's total population is fully vaccinated. Still a long way from the published figure of 50% of the total population. The goal of this study is to model and predict when the Indonesian government will be able to implement policies that will allow its citizens to move around without wearing masks, assuming that at least 50% of the Indonesian population has received the full dose of the vaccine. As a result, we require calculation guidelines to assist us.            Keywords: Mask; SES; FTS.  Abstrak: Pemerintah terus bekerja keras dalam upaya pencegahan virus COVID-19 dengan vaksin lengkap bagi masyarakat mengingat pentingnya vaksinasi lengkap sebagai aspek pertimbangan implementasi kebijakan beraktivitas tanpa masker. Saat ini, hanya 15,91 persen dari total penduduk Indonesia yang divaksinasi lengkap. Masih jauh dari angka yang dipublikasikan 50% dari total populasi. Tujuan dari penelitian ini adalah untuk memodelkan dan memprediksi kapan pemerintah Indonesia akan dapat menerapkan kebijakan yang memungkinkan warganya untuk bergerak tanpa memakai masker, dengan asumsi bahwa setidaknya 50% penduduk Indonesia telah menerima vaksin dosis penuh. Akibatnya, kami memerlukan pedoman perhitungan untuk membantu kami. Kata kunci: Masker; SES; FTS

Abstract

Linguistic intelligence is an important aspect that should be nurtured from an early age, as it serves as the primary tool for interacting and communicating with others. Language disorders can be categorized in various ways, one of which is speech delay. Speech delay occurs when a child struggles to express their wishes or thoughts to others, often resulting in unclear speech and a limited vocabulary compared to their peers. The research was conducted in Klambir V Kebun Village, Hamparan Perak District, Deli Serdang Regency, North Sumatra. The study aimed to design a speech therapy e-module with music therapy method. This research procedure adapts the ADDIE development model which consists of five stages including analysis, design, development, implementation, and evaluation. Based on the results of the validity test conducted with two validators, namely with media expert lecturers and material experts in each field. With the results of the validity test on the media getting a percentage of 83%, and on the material expert validation percentage of 78%. From the results of these two validations, the e-module of speech therapy with the music therapy method can be said to be feasible without revision to be tested in early childhood. Based on the results of the practical test, it can be concluded that the e-module of speech therapy with music therapy methods to alleviate speech delay problems in early childhood gets a score of 207 with a percentage of feasibility of 78%. So that children feel there is a new media used to sing.

Abstract

Penelitian ini bertujuan untuk merancang dan mengembangkan platform marketplace berbasis web personal untuk freelance digital artist menggunakan metode Research and Development (R&D) dengan model ADDIE. Berdasarkan survei terhadap 17 digital artist, teridentifikasi pain points signifikan pada platform existing seperti biaya komisi tinggi (41,2%), proses verifikasi rumit (47,1%), dan persaingan tidak sehat dengan karya AI (Artificial Intelligence) (52,9%). Platform dikembangkan menggunakan Laravel 12, PHP, MySQL, HTML, CSS, dan JavaScript, dengan delapan fitur utama: Profile, Link, Portfolio, Commission Management, Review & Rating, Management Review, Real-time Chat, FAQ, dan Contact. Evaluasi yang melibatkan 15 responden menunjukkan bahwa platform mencapai tingkat kelayakan 85,6% dengan kategori "Sangat Layak". Aspek Usability memperoleh skor tertinggi yaitu 88,8%, sedangkan Functionality memperoleh skor 88,0%, yang menunjukkan bahwa fitur yang disediakan sesuai dengan kebutuhan digital artist Indonesia. Platform ini berhasil menjawab tantangan pemasaran yang dihadapi digital artist dengan menyediakan solusi terintegrasi dengan model komisi 0%, sehingga artist dapat memperoleh margin keuntungan maksimal.

Abstract

PT Bringin Karya Sejahtera is a company engaged in services and facility management and requires an integrated inventory system that operates effectively. Inventory management, which is still carried out manually or semi-computerized, often causes various issues, such as discrepancies in stock quantities, delays in report preparation, and difficulties in monitoring and controlling items. Based on these problems, this study aims to design and develop a web-based inventory system capable of supporting more accurate, fast, and efficient data management of items. The development method applied in this study is the Waterfall model, which includes stages of requirements analysis, system design, implementation, testing, and maintenance. The system is built using a web-based programming language with centralized database support, allowing it to manage incoming and outgoing goods, stock inventory, and generate reports automatically and in real-time. The result of this research is a web-based inventory system that can improve inventory management effectiveness, reduce the potential for recording errors, and facilitate monitoring and reporting processes. With the implementation of this system, inventory management at PT Bringin Karya Sejahtera is expected to become more systematic, transparent, and efficient.
