Sistem Pakar Diagnosa Penyakit pada Sapi Menggunakan Metode Rational Unified Process
Get PDFCattle are livestock that have economic potential. Alongside their significant economic potential, there is a considerable risk, namely diseases in cattle. Diseases in cattle can spread rapidly and can be fatal, leading to death. These diseases can be caused by bacteria, viruses, fungi, and parasites. To prevent the spread of diseases in cattle, cattle farmers must first be aware of the diseases in their livestock so that prevention and treatment can be carried out as early as possible. Using the Rational Unified Process (RUP), a expert system for diagnosing diseases in cattle is built to support this process. The expert system is constructed using the Random Forest Algorithm, with its implementation based on a website to provide quick and practical diagnostic results, offering information relevant to the type of diseas
Rancang Bangun Sistem Keamanan Pintu Rumah Menggunakan Solenoid Door Lock dan Magnetic Switch Sensor dengan Notifikasi dan Kontrol Melalui Telegram
Get PDFCurrently, home security systems still rely on conventional locks that are prone to break-ins and do not provide real-time alerts. Conventional locks allow anyone with a duplicate key to access the house, and keys are often lost. To address this issue, a home door security system based on IoT with the ESP8266 microcontroller was developed. This system is equipped with a Solenoid Door Lock and a Magnetic Switch sensor. Integration with Telegram enables notifications when the door is opened and access to lock the door. A 4x4 keypad is provided as an alternative if the internet connection is lost. Testing results show the system functions well: accurate sensor detection, responsive password input, and quick notification reception. This system provides an effective and modern solution for home security

Estimasi Anggaran Biaya Pada Kapal Karunia Samudra I ( Studi Kasus Side Board Deck )
Get PDFThis research aims to create a faster and more precise MTOL (Material Take Off List) cost budget plan application and find out the data processing work system of this research application. The accuracy of preparing a budget in predicting the cost requirements of a construction greatly affects the success of the construction funding. In addition, it will also affect the success of its construction. In ship building projects this is the part that monitors the initial funding capability of the project. Thus, the preparation of a Cost Budget Plan (RAB), can be a solution to detail all the costs required in building ships such as material requirements, labor and so on. in making the application program using Visual Studio Code as software for storing and creating application programs, using XAMPP as a local web server supporter, as well as a place where the author can design and build databases. This application will be built using PHP and MySql as the database. The results showed that the estimated cost budget required on the side board of the Samudra 1 gift ship was Rp. 963.837.520 with a material load of 48,902.3 kg
Perkuatan Lentur Balok Hybrid Baja Ringan Paska Korosi Menggunakan Carbon Fiber Reinforced Polymer (CFRP)
Get PDFCorrosion of steel structures can cause a significant decrease in structural strength and sustainability. Therefore, to extend the service life and improve the performance of light steel structures, effective repair and strengthening methods are needed. Examples of buildings located in coastal areas such as reinforced concrete concrete beams. Currently, along with the progress of the times, the world of construction also continues to develop, one of which is by developing materials that can cover the weaknesses of the concrete, one of which is the presence of Fiber Reinforced Polymer (FRP) material. In this study, the author used Carbon sheet FRP with beam dimensions of 1.3 m × 0.25 m × 0.15 m totaling 3 beams. 1 for control beam, 1 corroded beam, and 1 for corroded beam that has been reinforced using Carbon Fiber Reinforced Polymer (CFRP)
Rancang Bangun Sistem Proteksi Motor Induksi 3 Fasa Dari Gangguan Beban Lebih Berbasis Internet Of Things (IOT)
Get PDFMotor listrik sudah menjadi kebutuhan pokok bagi para pelaku industri untuk mendukung proses produksinya. Penggunaan motor listrik dipilih karena mempunyai sifat mudah dioperasikan dan tidak menimbulkan polusi suara dibanding dengan pengunaan tenaga motor diesel atau motor bakar. Motor listrik digunakan untuk menggerakkan beban atau sebagai penggerak pengangkatan beban. Sistem proteksi motor induksi tiga fasa dipasang untuk melindungi motor pada saat bekerja sehingga meminimalisir kerusakan yang diakibatkan dari gangguan-gangguan yang muncul. Saat ini sistem proteksi motor induksi masih tergolong manual, maka diperlukan sebuah sistem proteksi otomatis sehingga dapat menjaga motor induksi tetap bekerja dan minim gangguan. Sistem ini menggunakan Nodemcu ESP8266, sensor arus dan sensor suhu. Modul Wifi sebagai transmisi data, Relay SSR sebagai pemutus daya, serta blynk apps sebagai aplikasi pemonitornya karena memiliki keunggulan dan kemudahan dalam pengoperasiannya. Metode penelitian yang digunakan adalah metode Penelitian dan Pengembangan. Pengujian yang dilakukan adalah dengan kalibrasi sensor, dan uji kinerja sistem
Pengaruh Faktor Air Semen Pada Penggunaan Zat Aditif PolynevaHE
Get PDFPolyneva HE is an additive to reduce the use of water in the concrete mixture, so that the mixture remains easy to work with or the mixture becomes plastic (does not change shape). In addition, the addition of Polyneva HE percentage can also accelerate the hardening of the concrete. The results
of this test show that the use of Polyneva HE, as an additive in the concrete mixture has a good compressive strength value. After testing, it can be seen that this system can be used and provides a better value with a total compressive strength value of 30 Mpa. The concrete mixing method using Polyneva HE additives uses the SNI 03 - 2834 - 2000 job mix design, additives in the concrete mixture with variations of -5%, -10%, -15%, + 5%, + 10%, and Normal Concrete + Normal. Concrete that is cured for 3 days, 7 days, 28 days is then tested to obtain the slump value,
compressive strength value, and unit weight of the concrete. From the results of this test, the highest compressive strength value was obtained in the variation of 15% Water Reduction + 0.8% Polyneva HE. Polyneva HE also increases the concrete unit weight with a weight between 12000-13000. The
highest slump value was obtained at 10% Water Addition + 0.8% Polyneva HE of 14.8
Algoritma Decision Tree Untuk Memprediksi Perilaku Santri Pada Pondok Pesantren Madani
Get PDFMadani Islamic Boarding School has a very important role in shaping the character and personality of students as an Islamic educational institution. To strengthen character education in Islamic boarding schools, a process of habituation to honest, good and disciplined behavior is needed. However, Islamic boarding school managers experience difficulties in assessing and understanding student behavior. The aim of this research is to predict student behavior from an early age using the Decision Tree algorithm. This prediction can help Islamic boarding school managers identify students who have the potential to experience problems. The research results show that the Decision Tree algorithm can predict student behavior by considering attributes such as attendance, discipline, social and final grade data. Through Decision Tree steps, this algorithm is able to identify important features in student behavior. Apart from that, this research provides benefits for Islamic boarding school managers, teachers and parents of students in understanding student behavior and overcoming problems that arise
Rancang Bangun Oven Pengering Biji Pinang Kapasitas 8 Kg Berbasis Energi Surya
Get PDFThe traditional drying process of areca nut seeds is time-consuming, requires a large space, and is highly dependent on sunlight. Therefore, a solar-powered areca nut seed drying oven was designed to address these challenges. The oven uses a heater as a heat source and solar panels as a power source, enabling drying to be carried out at night or during cloudy weather. The design process includes conceptual design, oven construction, solar panel installation, and testing phases. Observations were made at temperatures of 50°C, 60°C, and 70°C with an initial seed weight of 8 kg, targeting a moisture reduction of 12-14%. The test results show that this oven effectively reduces the moisture content of the seeds at an optimal temperature of 70°C over ±10 hours, achieving a moisture reduction of 14%, equivalent to 6.88 kg. This design introduces the use of solar energy as an alternative power source for areca nut seed drying, enhancing drying efficiency and quality while reducing dependency on weather conditions and conventional energy sources
