Abstract

Development of a grid-based clustering mechanism to improve LEACH performance in the Wireless Sensor Network environmentLow Energy Adaptive Clustering Hierarchy (LEACH) merupakan algoritma routing pada Wireless Sensor Network (WSN) berbasis cluster. LEACH memilih sebuah node sebagai cluster head (CH) yang tugasnya untuk melakukan komunikasi dengan sink maupun guna mengumpulkan data dari member node. Persebaran CH pada LEACH yang dikatakan acak, kadang mengalami masalah mengingat rumus probabilitas pada tiap round. Hal ini akan menyebabkan CH yang terpilih bisa berada di tepi area, juga terjadinya pemborosan energi karena jalur yang terbentuk akan menjadi panjang. Oleh karena itu, kami ingin mengembangkan routing protocol G-LEACH menggunakan teknik merge CH dalam suatu area (grid) disertai beberapa parameter yang relevan, seperti posisi node, node dengan sisa energi terbesar, dan jarak yang dihitung dalam tiga jarak yaitu jarak node menuju cluster center, jarak node menuju merge CH, dan jarak merge CH menuju sink. Hasil pengujian menunjukan bahwa dengan menggabungkan cluster (merge CH) pada transmisi data menuju sink pada protokol G-LEACH dapat menghasilkan masa hidup jaringan yang lebih lama pada seluruh operasi node, energi yang dibutuhkan pada semua node lebih rendah, dan lebih banyak paket data yang dikirim dan diterima oleh sink. Low Energy Adaptive Clustering Hierarchy (LEACH) is a routing algorithm in a cluster-based Wireless Sensor Network (WSN). LEACH selects a node as a cluster head (CH) whose responsibility is for communicating with sinks and collect data from the node members. The distribution of CH on LEACH, which is basically random, sometimes has a problem in remembering the probability formula on each round. This may make the selected CH on the edge of the area as well as generate energy waste because the pathway formed will be lengthy. Therefore, we would like to develop the G-LEACH routing protocol using a merge CH technique in one area (grid) with several relevant parameters, such as the position of the node, the node with the largest remaining energy, and the distance calculated in three distances: the distance of the node to the clustercenter, the distance of the node to the merge CH, and the distance of the merge CH to the sink. The test result showed that combining clusters (merge CH) in the data transmission to the sink in the G-LEACH protocol could produce a longer network life on all node operations, lower energy required for all nodes, and more data package sent and received by the sink.

Abstract

Indonesia is one of the largest archipelagic countries in the world, one of the challenges is that the existing internet network is not optimal and should be evenly distributed throughout Indonesia. This article is one of the efforts to increase the capacity and use of the internet, especially to support the education process which should be evenly distributed in various regions in Indonesia, not only in Java but also in areas outside Java. especially in East Nusa Tenggara. NTT is one of the areas discussed in this article, specifically at Kefamenanu 1 State Vocational School. This article puts forward some essential aspects in the development and installation of the internet in this school, including using the right measurements of Quality of Service (QoS). QoS includes many things such as Throughput, Bandwidth, Packet Loss, and other parameters that are essential in building and analyzing internet networks that have a wide scope, especially for the Education level. Vocational High Schools are not only expected to be able to use the internet but also build, design, install, and perform detailed analysis on the internet network they build. Two essential networks must be able to be installed, i.e., a Wireless Network and Local Area Network.

Abstract

SMKN Kakuluk Mesak is a vocational high school located in Dua Laus Village, Kakuluk Mesak District, Belu Regency, East Nusa Tenggara Province, which prepares students to work in specific fields. Students can continue their education at SMK after completing their education at the junior high school level. The study period for SMK students is carried out for three to four years of learning, which is divided into three years of study at school and one year in the related industry department. SMKN Kakuluk Mesak has five majors: APAT, NKPI, WBE, TKPI, and APHPI. One of the problems at SMKN Kakuluk Mesak in terms of technology is the manual attendance and grading of students. Attendance and grades are recorded using books. Therefore, a web-based student attendance information system with QR code is needed to facilitate the student attendance process. This system is built using the waterfall method, which is a systematic and directed approach to developing software in which it is used step by step until it runs in order. This research resulted in a website-based student attendance information system with QR code that helps the school manage attendance data and students can view grades and attendance records anytime and anywhere.

Abstract

Citronella oil produced by the “Gema Industri” farmer group is the only processor of essential oils made from citronella plants (Cymbopogon nardus) in North Central Timor Regency (TTU). The location of this home industry is in Oenenu Village, Bikomi Tengah District and has been carried out since 2000 until now using very simple equipment. Citronella oil distillation activities are carried out twice a week including marketing activities. The demand for citronella oil, especially in TTU Regency, which is adjusted to the purchasing power of the community, is not limited to pure citronella oil, but other products such as mixing several ingredients for medicinal purposes according to local wisdom such as massage oil or for treating toddlers in the form of a mixture of coconut oil and citronella oil in a ratio of 5:1 and other herbal ingredients. The results from the sale of products created by the “Gema Mandiri” farmer group have allowed this farmer group to survive until now. Product marketing is still done manually and relies on acquaintances and regular customers and there have been no more modern marketing breakthroughs such as the use of promotional media and digital marketing. In addition, the packaging of citronella oil is still limited to one size variant (100 ml) and has not been well designed, namely made of transparent plastic that does not meet product safety requirements, on the other hand the labeling is still very simple and does not fully describe the benefits of the product. The purpose of PkM is to help the "Gema Industri" farmer group in increasing market share by improving safer packaging with various volume and presentation variations so that it can increase people's purchasing power. The method used in the PkM activity is carried out in 2 stages, namely lectures and training on the use of packaging and labeling and training in selling via the internet in this case promotion on social media. In this activity, the Community Service Team provided a transfer of IPTEKS on safe essential oil packaging such as the use of dark bottles that protect the product from direct sunlight. The community service team also introduced various forms and presentations of citronella oil with varying sizes starting from 10 ml in the form of a roll on so that it is more practical and affordable for the community, besides that there are other forms that are also practical in their presentation. Various packaging must also be supported by good promotional media, for that the devotion team designed a business leaflet that describes a brief profile of the "Gema Industri" Farmer Group, the steps for making citronella oil and also an introduction to the products produced. With this business leaflet, it is hoped that the Gema Industri Farmer Group will find it easier to promote its products and hopefully it will be better known by the public. Members of the farmer group are also trained on how to promote and sell citronella oil and other citronella oil products via the internet (website and social media) in addition to using the leaflets that are distributed and the participation of the farmer group in exhibitions. The devotion activity on the use of safe packaging for the production of citronella oil at the GEMA INDUSTRI Farmer Group in Oenenu Village has gone well and brought benefits to the group. Citronella oil products are currently packaged in a variety of attractive packaging variations, hopefully it can further increase public interest in using them.

Abstract

The development of information and communication technology has become an important element in supporting all organizational activities, one of which is a religious institution such as GMIT Petra Kefamenanu. This church utilizes the internet network to support worship activities, administration, and educational services. However, the increasing needs and number of users cause slow connections and the emergence of network security risks. Based on these conditions, this study aims to design and implement an optimal and secure network infrastructure blueprint using a firewall as a network security system and a Network Development Life Cycle (NDLC) approach as a development method. This research was conducted through five NDLC stages: network requirements analysis, design, blueprint , simulation using Cisco Packet Tracer , configuration implementation with Mikrotik, and monitoring. The results of the study show that the network design based on star technology (star topology) and firewall configuration that includes DHCP, NAT, and Layer 7 Protocol features successfully increased overall security and connection efficiency. The firewall is able to limit unproductive access and prevent potential cyber threats. This implementation proves that the blueprint is designed not only for a systematic and extensive network structure, but also provides comprehensive network protection against external attacks, thus supporting more effective church services.

Abstract

Penelitian ini bertujuan untuk mendapatkan informasi sebaran curah hujan tahunan dan kondisi hidrogeologi Kabupaten Timor Tengah Utara. Kajian tentang parameter penentu kekeringan seperti curah hujan dan kondisi hidrogeologi diharapkan dapat menjadi masukan sebagai kerangka acuan dalam mitigasi kekeringan. Penelitian dilakukan dengan menggunakan metode deskriptif melalui beberapa tahapan, yaitu tahap pengumpulan data sekunder berupa data curah hujan dan data hidrogeologi, tahapan pengolahan data dan deskripsi pata hasil. Pembuatan peta curah hujan tahunan menggunakan data CHIRPS berupa data hujan bulanan selama periode 2018-2023. Data tersebut diolah dengan Arcgis melalui local cell staticstics tools untuk mendapatkan data raster rata-rata hujan tahunan. Selanjutnya data raster diubah menjadi data point, interpolasi point dan kemudian reklasifikasi. Hasil menunjukkan bahwa rata-rata curah hujan tahunan di Kabupaten Timor Tengah Utara adalah 1155-1893 mm/tahun. Ini mengindikasikan bahwa Kabupaten Timor Tengah Utara didominasi oleh curah hujan rendah. Kajian tentang kondisi hidrogeologi menunjukkan bahwa Kabupaten Timor Tengah Utara memiliki litologi akuifer berupa batuan gamping, endapan lepas, batuan malihan dan beku, batuan padu dan batuan volkanik, dan produktivitas akuifer didominasi oleh akuifer (bercelah atau sarang) produktif kecil dengan air tanah langka. Kedua peta dapat digunakan untuk mengidentifikasi potensi kekeringan.

Abstract

Learning linear inequalities still encounters challenges in terms of visualization and interactivity, while the evaluation of digital learning media generally relies only on descriptive analysis, resulting in less comprehensive findings. This study aims to evaluate the effectiveness of RShiny-based digital learning media through the integration of Multiple Correspondence Analysis (MCA) and K-Medoids clustering as a scientific novelty in examining multidimensional patterns of student perceptions. The media was implemented among 101 tenth-grade students from three schools using a five-construct questionnaire that had been previously tested for validity and reliability. The results showed that most students responded positively to the interface, clarity of material, and ease of use; MCA identified dominant indicators including increased motivation, conceptual understanding, and assessment outcomes, while K-Medoids produced two perception clusters, namely highly positive and moderate. Therefore, the RShiny-based media is proven effective in enhancing students’ motivation, conceptual understanding, and academic performance in learning linear inequalities.

Abstract

Abstrak. Teknologi jaringan komputer saat ini telah memasuki hampir keseluruhan segi kehidupan. Sangat sulit pada saat ini menemukan bidang kegiatan yang belum tersentuh oleh teknologi jaringan komputer. Hal ini dapat dilihat dari pengguna fasilitas jaringan komputer, baik untuk keperluan suatu instansi maupun untuk keperluan pribadi. Teknologi jaringan komputer telah menjadi salah satu hasil penting untuk diterapkan dalam era globalisasi dan komputerisasi. Jaringan komputer merupakan satuan komputer yang saling berhubungan satu sama lain dengan menggunakan protokol komunikasi yang melalui media kominukasi agar dapat saling berbagi informasi. Jaringan komputer sendiri bukanlah hal yang baru karena pada setiap instansi telah menggunakan dan memanfaatkan jaringan komputer. [1] Manajemen bandwith merupakan salah satu yang penting dalam jaringan komputer, dimana manajemen bandwith berfungsi sebagai pengatur jaringan bandwith yang setiap pengguna jaringan tersebut memperoleh bandwith yang merata walaupun dengan jumlah pengguna yang banyak. Manajemen bandwith juga merupakan ukuran, lebar dan luas saluran data yang melewati sebuah koneksi yang dikirim melakui jaringan internet. Manajemen bandwith adalah suatu proses pengontrol paket yang dikirim melalui jaringan agar paket yang dikirim tidak terjadi kegagalan diakibatkan koneksi jaringan yang buruk atau kemacetan dalam jaringan. Untuk mengatur manajemen bandwith dibutuhkan metode yang tepat agar permasalahan bisa teratasi sehingga akses jaringan menjadi optimal Abstract Computer network technology has now entered almost every aspect of life. It is very difficult today to find a field of activity that has not been touched by computer network technology. This can be seen from the use of computer network facilities, both for institutional purposes and personal needs. Computer network technology has become one of the important outcomes to be applied in the era of globalization and computerization.A computer network is a unit of computers interconnected with one another using communication protocols through communication media so that they can share information. Computer networks themselves are not something new, since every institution has already used and benefited from them (Heryanto, 2019).Bandwidth management is one of the important aspects in computer networks, where bandwidth management functions as a regulator to ensure that every network user receives fair bandwidth distribution even with a large number of users. Bandwidth management is also defined as the measurement, width, and capacity of the data channel passing through a connection that is transmitted over the internet network.Bandwidth management is a process of controlling packets transmitted through the network so that packet delivery does not fail due to poor connections or network congestion.
