Pada penelitian sebelumnya telah dihasilkan sistem pengontrol lampu menggunakan SMS gateway dengan bantuan perangkat mikrokontroler. Hal tersebut memberikan kemudahan manusia terhadap pengontrolan on/off lampu rumah, sehingga tidak perlu lagi repot untuk menekan saklar lampu yang berada di dinding rumah. Seiring dengan perkembangan teknologi, telah berkembang juga perangkat pengontrol, yaitu Raspberry Pi 3 yang juga sering disebut sebagai mini Personal Computer (PC). Pada penelitian ini digunakan perangkat Raspberry Pi 3 untuk menerapkan Sistem Operasi Raspbian Jessie pada sistem pengontrol lampu serta menggunakan metode action research dalam memperoleh hasil penelitian sesuai dengan tujuan. Selain itu, dibutuhkan juga bahasa pemrograman phyton untuk dapat menjalankan user interface sistem pengontrol lampu berbasis Raspberry Pi 3. Pada pengujian sistem pengontrol lampu, digunakan lampu pijar senter dengan model fitting E10 dan lampu pijar rumah dengan model fitting E27. Hasil penelitian ini menunjukan bahwa Raspberry Pi 3 dengan Raspbian Jessie dibantu dengan perangkat modul relay dapat digunakan untuk mengontrol on/off lampu pijar rumah (model fitting E27) dengan mudah dan baik menggunakan user interface berbasis web.
PT. Sinergi Persada Medica (SPM) merupakan salah satu perusahan yang bergerak sebagai distributor berbagai jenis obat kesehatan yang berada di Propinsi Sumatera Selatan. Permasalahan yang terjadi pada PT. SPM adalah proses penentuan persiapan stok obat, dimana pencatatan stok obat yang berlangsung saat ini pada PT. SPM masih menggunakan buku stok sehingga data stok obat yang tersedia dan habis tidat tercatat dengan akurat. Selain itu, pencatatan stok obat secara manual ini juga tidak bisa dijadikan acuan untuk menentukan persiapan stok obat sesuai dengan kebutuhan konsumen. Oleh karena itu, pada penelitian ini dibangun suatu sistem informasi menggunakan perhitungan Weighted Moving Average (WMA) dengan bahasa pemrograman PHP, dimana proses penelitian ini dilakukan dengan menggunakan metode penelitian action research. Hasil penelitian ini merupakan suatu sistem informasi peramalan persediaan untuk menentukan persiapan stok obat yang dibangun dengan Adobe Dreamweaver dan berbasis web, sehingga mudah digunakan dengan tampilan yang dinamis. Setelah itu, pengujian sistem informasi ini menggunakan bantuan localhost yang telah disediakan oleh program XAMPP serta dapat diakses menggunakan browser, dimana dari hasil pengujian menunjukan bahwa sistem informasi ini dapat mengelola data obat, stok obat, data pelanggan hingga data permintaan obat yang digunakan sebagai acuan penentuan persiapan stok obat.
Internet network security in a company is critical. Currently, the use of wireless devices as a local data traffic controller is very widely used. However, this tool is vulnerable to network security breaches if it is not accompanied by excellent security of the network system. PT. Taspen (Persero) Palembang has problems with the Wireless network and does not have an excellent security system. It causes users who are not employees to use the internet network at the company, making employee operations slow and vulnerable to burglary. Therefore, in this PKM activity, RADIUS Technology is applied as internal network security. Every user who wants to access the internet network at the company must first log in. This activity aims to train employees of PT. Taspen (Persero) Palembang to access a wifi network that uses RADIUS Technology. It starts from accessing the wifi network, logging in, to logging out of the wifi network. This activity is carried out online by utilizing the Zoom Meeting application. The results obtained indicate that the network system security of PT. Taspen (
In today's modern era media for learning are widely spread in the digital world such as the internet, there are many websites that provide facilities to learn many things, one of them is programming language. Petani Kode website is one of the websites that can be used to learn things. To measure the usability level of this website, a test was carried out using the SUS questionnaire containing 10 statements. Then the data collected will be calculated using several rules in calculating the SUS score, after calculating the average SUS score of all respondents to be compared using the adjective table. In this study, 30 respondents were obtained. people were then selected again based on the type of work of the respondents, into 20 respondents who came from among students. from the 20 respondents, an SUS score of 72.25 was obtained, and according to the adjective rating system the score was in the OK category with grade scale C and the level of acceptance was ACCEPTABLE.
Learning media is a tool used by teachers to convey subject matter to students or media used by students to deliver assignments given by the teacher. In this training activity, computer-based learning media were introduced for presentations using Microsoft PowerPoint, which students of SMP Patra Mandiri 2 Palembang could use to present assignments given by the teacher to the front of the class with attractive shapes and appearances. Community Service Activities (PKM) in the form of training are carried out for two days, in which students are required to be able to make presentation materials using Microsoft PowerPoint and present the material they made in front of the computer laboratory room. This activity is carried out in direct and interactive practice, where students directly practice the material provided by the PKM Team, and students can also have direct discussions with the PKM Team. Before implementing the training activities, students were given a written knowledge test to determine the level of students' understanding of the training material to be delivered. Only 20% of the student participants often made materials using Microsoft PowerPoint. After two days of implementing this training activity, an evaluation was carried out regarding the knowledge and abilities of the student participants in creating and presenting material using Microsoft PowerPoint.
