Abstract

We propose learning Matematika GASING to help students better understand the addition material. Matematika GASING is a way of learning mathematics in an easy, fun and enjoyable fashion. GASING is short for GAmpang, aSyIk, and menyenaNGkan (Bahasa Indonesia for easy, fun and enjoyable). It was originally developed by Prof. Yohanes Surya at the Surya Institute in Indonesia to improve the mathematics education in Indonesia. In Matematika GASING, there is a step called “the critical point” that needs to be mastered for each topic. The focus of our research is the critical point for addition, that is addition of two numbers between 1 − 10 with a sum less than 20. The subject is a matriculation class at STKIP Surya and the research method used is Classroom Action Research. The statistics obtained is described using Qualitative Descriptive Statistics.Keyword: Matematika GASING, Addition, Critical Points, Classroom Action Research. DOI: http://dx.doi.org/10.22342/jme.5.2.1500.160-169

Abstract

This Community Service activity was carried out because they we the teacher's lack of ability in making their own learning videos. This ability is very much-needed in this pandemic, because students have to do distance learning. Universitas Pembangunan Jaya conducts training for teachers at MTs Miftah Assa'adah School located in South Tangerang area. In distance learning, the use of video media is needed by students. Teacher training is conducted using a combination of online and offline methods. The teachers were also given hand-on training to create, edit and upload the learning videos they made. Training using common applications and can be obtained easily. The applications used are also applications that do not require high computer resources, so they can be done with only standard devices. For example MS Power Point, Canva and Movie Maker, VLC and even Zoom. Of the 10 indicators used as a measure, 8 of them showed an increase of over 50%. The post-test results at the end of the training also showed an improvement in the general abilities of the training participants

Abstract

Situation during COVID19 pandemic, requires all schools to conduct online learning. This condition is done to prevent the spread of pandemic. The problem is that the infrastructure is not fully supported. Learning in marginal areas is still constrained by the difficulty of the signal or internet connection. This research was conducted to obtain an infrastructure design that can be used in areas with minimal internet connection, or even no internet network connection. Using R&D, the research begins by designing a network device on the school side – Acces Point, also a tool to expand coverage - repeater. Furthermore, design and testing of signal amplifier antennas that can be used on the client side is carried out. For the client side, several types of amplifier antennas are made that can be used to receive Wifi frequencies. There are three types of antennas that are made and tested, namely Yagi, Yagi Cross, and cantennas. Both are Unidirectional antenna. Connection quality is measured with a Wifi analyzer device to determine network quality. As for mobile phones, it is measured using the Wifi Master Key. The result obtained is a WELAN infrastructure design which is equipped with unidirectional antenna design with a total range of 8 Km.

Abstract

An important factor influencing the success of regional development, one of which is the human resources (HR) that have a role in increasing the productivity and competitiveness of a region. An analysis of the competitiveness of a region needs to be carried out to identify weaknesses and strengths in human resource aspects that will have an impact on economic performance and people's welfare. This study aims to analyze the Regional Competitiveness Index (IDSD) of Banten Province in terms of human resources using several indicators, including education level, availability of employment, health, and investment environment. The method used is descriptive analysis and regional competitiveness index calculation. The data used in this study were obtained from the National Research and Innovation Agency. The results of the study show that Banten Province has an IDSD value on the health pillar of 3.75. From the health pillar, there are 3 regencies/cities that have a higher IDSD score, namely Tangerang Regency with a score of 3.85, Tangerang City with a score of 4, and South Tangerang City with a score of 4. Meanwhile, the IDSD score on the skills pillar has a score of 3.44. There were only 3 that had a higher IDSD score, namely Tangerang City with a value of 3.86, Cilegon with a value of 3.53, and South Tangerang City with a value of 3.79. Therefore, it is necessary to make efforts to improve the quality of human resources in Banten Province by taking into account the factors that affect competitiveness, including education, availability of fields, employment, health, and the investment environment.

Abstract

Students must have a solid understanding of the Independent Learning-Independent Campus Policy, which was introduced by the Ministry of Education, Culture, Research, and Technology in 2020. Students are unwilling to participate in programmes due to a lack of knowledge and false information about it, so an information system is needed to prepare and handle these programmes. The goal of this study is to create an UX design for information system that will enable students in understanding programme policies and participating in programme activities. The technique of this study focuses on creating UX design that satisfy the policy's requirements while taking into account the needs of students. Students from Universitas Pembangunan Jaya's Department of Information Systems make up the data population. Google Sprint Design is the UX design methodology employed in this study. The six phases of the Google Sprint design process are Understand, Define, Sketch, Decide, Prototype, and Validate. The application development team uses the UX design outcomes after they have been demonstrated to be effective. It has been demonstrated in this study that design outcomes can take system stakeholders' needs into account.

Abstract

Protokol Internet Control Message Protocol (ICMP) merupakan protokol pendukung pada lapisan jaringan yang berfungsi menyediakan informasi kendali serta pelaporan kesalahan dalam proses pengiriman paket IP. Pada jaringan Local Area Network (LAN), ICMP banyak digunakan sebagai alat troubleshooting dasar untuk menguji konektivitas, mendeteksi jalur paket, dan menganalisis kegagalan komunikasi antarperangkat. Penelitian ini bertujuan untuk menganalisis efektivitas ICMP dalam menangani permasalahan konektivitas jaringan melalui simulasi LAN menggunakan Cisco Packet Tracer. Metode penelitian dilakukan dengan merancang topologi jaringan sederhana, melakukan konfigurasi IP dan routing, serta mensimulasikan berbagai skenario gangguan seperti kesalahan konfigurasi IP, gateway tidak tersedia, dan pemutusan link jaringan. Pengujian dilakukan menggunakan perintah ping dan traceroute untuk mengamati respon pesan ICMP. Hasil penelitian menunjukkan bahwa ICMP mampu memberikan informasi diagnostik yang jelas melalui pesan echo reply, destination unreachable, dan request timed out, sehingga memudahkan identifikasi sumber permasalahan jaringan. Penelitian ini menegaskan bahwa ICMP merupakan alat fundamental dalam troubleshooting jaringan berbasis TCP/IP, khususnya untuk pembelajaran dan simulasi jaringan.

Abstract

Komunitas Historia Indonesia (KHI) is one of the leading historical communities in Indonesia that plays an important role in preserving and disseminating historical knowledge to the public. In the digital era, the challenges in maintaining the continuity of knowledge and collaboration between community members are increasing. Therefore, the implementation of the Knowledge Management System (KMS) is relevant to manage, store, and disseminate historical knowledge effectively. This article discusses how the implementation of KMS can improve the effectiveness of KHI community activities, as well as the obstacles and opportunities faced in the process. The method used is a literature study of KMS literature and documentation of community activities. Keywords : Knowledge Management System, Historical Community, Knowledge Preservation, Komunitas Historia Indonesia.
