Abstract

Recording of drug sales and purchase transactions is a process carried out at the Lillis pharmacy. Currently the transaction process is done manually or still using books that can cause difficulty in knowing the amount of drug stock, the slow recording of transactions, the difficulty of finding expired drug data, the drug return process has difficulty in finding so many transaction notes, bad possibilities that can occur is if the memorandum is lost before the transaction data is entered into the report book, the slowness of making sales and purchasing reports. The purpose of the research is the design, development and application of the drug distribution process using a Java-based NetBeans IDE information system. The design of the information system is modeled into diagrams in UML (Unified Modeling Language) and the method of developing the System Development Life Cycle (SDLC) with the Waterfall model. The test results of the Pharmacy Information System obtained 99% of the interfaces tested properly. The research data was taken from Lillis Pharmacy in 2019. This research is expected to be able to help Lillis Pharmacy to simplify and speed up the processing of drug sales and purchase data optimally.

Abstract

Motor vehicle theft is a criminal problem that very often occurs in the community. Along with the development of technology and the level of demand for motor vehicle safety in the community that begins to increase. One of the devices that has been developed is Internet of Things (IoT) technology which is able to connect and facilitate the communication process between machines, devices and humans via the internet network. The purpose of this research is to develop a monitoring application that utilizes IoT technology as a medium for tracking the location of motorized vehicles. This research consists of 3 main system components, including the End Device System found on the Raspberry Pi device, Web Service (Back-End System) as a service for data transfer, and Front-End System user interface in the form of a website application. This system has several main features, including realtime tracking and is equipped with an activity log which can be used to determine the identity of the vehicle user. Users can access these features through the application from the website. Based on the trials conducted, this system works well on motorized vehicles, however, this system has more dependence on the internet network available in each region.

Abstract

The data processing of Al-Amin's Play Group student scores is still done manually, namely by handwriting on student assessment booksheets, this takes a long time and is not effective. The development of the number of students that increases from year to year requires accuracy in providing assessments without any mistakes and repetition of the same data. The purpose of this research is to design and make student assessment applications with object-oriented programming in the Al-Amin Play Group. Using the Waterfall model System Development Life Cycle (SDLC) method, the design based on the Unified Modeling Language (UML) and the Java Netbeans 8.2 programming language MySQL database. The research data includes student data, student attendance every semester from 2018 to 2019. The final result of the research is an object-oriented student assessment system that can be accessed through a laptop, personal computer (PC) device which is expected to help the foundation to facilitate data collection and processing of value data students and can see the progress of students in each semester at the Al-Amin Play Group in Kedewan Village. The system test results were declared feasible in terms of functionality, amounting to 97.9% in black box testing.

Abstract

KKL is an academic activity that must be taken and taken by all Diploma and Bachelor students in groups or individually. At the STTR Cepu campus, the process of submitting KKL to the assessment is still done manually, so it takes quite a long time to search for student data, missing data and inconsistent KKL activity data. The purpose of this research is to design and develop an Information System for Online KKL Activities at the STTR Cepu campus. Using the waterfall model system development life cycle (SDLC) development method, design based on Unified Modeling Language (UML) and PHP programming language with MySQL database. The research data includes student MPA data for the last 3 years 2015-2018. The results of this study are the application of an KKL activity information system that helps make it easier for students in the process of registering activities, submitting activities and proposing guidance processes and reports on the results of KKL activities as well as being more time efficient and faster..

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh belokan patah (elbow miter) tehadap pressure drop aliran dua fase. Penggunaan elbow pada sistem perpipaan sangat umum sekali karena untuk memenuhi kebutuhan desain dan geometri sistem perpipaan. Piranti uji menggunakan pipa acrylic dengan diameter dalam 32 mm pada posisi vertikal, disambung dengan elbow miter 45odan dilanjutkan dengan pipa dengan kemiringan 45o. Air dan udara digunakan sebagai fluida kerja. Pengujian dilakukan dengan variasi kecepatan superfisial cairan (USL) mulai 0,30-0,50 m/s dan kualitas volumetrik udara (β)= 0,06-0,22. Pola aliran didokumentasikan dengan kamera digital dan pengukuran pressure drop menggunakan manometer tipe-U. Hasil pola aliran dengan variasi range USL 0,30-0,50 m/s menunjukkan pola aliran bubble flow, seiring meningkatnya nilai USL konsentrasi bubble cenderung menempati inner elbow. Pressure drop aliran dua fase menurun seiring meningkatnya nilai β pada aliran hal tersebut dikarenakan menurunnya nilai massa jenis aliran. Pressure drop terendah terjadi pada USL 0,30 m/s dan β 0,22 yaitu sebesar 3628,591 N/m2, sedangkan nilai pressure drop tertinggi terjadi pada USL 0,50 m/s dan β 0,06 yaitu sebesar 3892,67 N/m2.
