Abstract

Internet access has become a primary human need. During the COVID 19 pandemics, almost all activities such as studying and working online. However, several rural areas still did not have internet access due to weak cellular signals. Internet access in rural areas can have various alternatives, such as VSAT (satellite). It needs an inexpensive and precise way to complete the internet access coverage because many customers were concentrated in areas far from the VSAT terminal. WLAN 802.11n was an alternative way to expand the range of internet coverage with low cost and easy implementation. Our case study uses the 5GHz frequency with a sectoral antenna as the multi-hop point-to-point backhaul network's frequency to avoid the risk of channel interference on the backhaul. On the other hand, 2.4GHz frequency with an omnidirectional antenna serves smartphone customers. On the test results, the network latency between multihop access point, has a maximum value of 19,894 ms. This result means that the latency obtained can be categorized as preferred VoIP services based on ITUT G.1010 in the local network. Then for the customer on the fourth hop, 3968 meters from the VSAT terminal, the UDP data rate of 1.04Mbps was stable, and the TCP data rate decreased to 1.26Mbps. This paper emphasizes the use of multihop 5Ghz WLAN 802.11n as a backhaul to expand internet access coverage from VSAT in rural areas, where the concentration of customers was far apart and there were many buffalo horn barriers in traditional homes and buildings.

Abstract

Data storage media, or what is often referred to as a database is something that is quite vital for technological developments. As the amount of data increases, it allows database services to experience downtime. For this reason, it is necessary to build an infrastructure that can replicate itself, so that it will avoid downtime. This infrastructure can be built using a container orchestration tool called Kubernetes which has high availability and autoscaler features, so it can replicate and guarantee service availability, to avoid downtime. This research builds a MongoDB NoSQL database service. This service is built using micro Kubernetes clusters from several different data centers. This service also implements a horizontal pod autoscaler feature that is capable of replicating pods, to increase high availability and avoid downtime. The autoscaling process will be tested by providing a load request for the service. Testing is done several times on each server. This study will compare the MongoDB service that was built monolithically with a micro Kubernetes cluster, and with HPA features and without HPA features by paying attention to several things. Based on Response Time, Response Code per Seconds, and CPU Usage, the results obtained are that the service built on a micro Kubernetes cluster with HPA features is the best, with a constant response time value below 100 ms, Response Code per Seconds reaches 500 threads per second. seconds, and CPU Usage in the range of 30 – 55%.

Abstract

One of the most vital senses for humans is sight. Humans utilize their eyes to take in visual information that is used for a variety of tasks, but vision problems are prevalent, ranging from minor disorders to serious disorders that can result in blindness. Cataracts are one of the factors contributing to this vision loss. In Indonesia, cataracts alone account for 81 percent of cases of blindness, and 40 percent of those affected don't even realize they have them. A technique for early cataract identification using digital photographs is one way to lower the incidence of cataract-related blindness. We used Support Vector Machine (SVM) and Convolutional Neural Network (CNN) techniques to create a cataract detection system. These two techniques are used to categorize normal eye classes, immature cataracts, and mature cataracts. A digital image that has been downsized to 64x64 pixels in Joint Photographic Group (JPG) format that was taken from earlier study serves as the input data. Support Vector Machine (SVM) and Convolutional Neural Network (CNN) methods used in the cataract detection process provide optimal results. The Support Vector Machine (SVM) method itself produces an accuracy value of 96.67%, while the Convolutional Neural Network method produces a better accuracy value of 98.89%.

Abstract

Kantor Desa Sukapura adalah pusat administrasi dan kepemimpinan Desa Sukapura yang beralamat di Jl. Sukapura No.54, Sukapura, Kec. Dayeuhkolot, Bandung, Jawa Barat 40267. Kepala Desa Sukapura adalah H.Ganjar Sukma Wibawa, A.Md. Jarak Kantor Desa Sukapura dari Kampus Telkom University adalah 500 meter. Di masa Pandemic COVID-19, Kantor Desa Sukapura sudah menjalankan beberapa protokol di antara nya adalah; menjaga jarak, mencuci tangan, menggunakan masker, dan WFH Sebagian Sudah dilakukan pengukuran suhu tubuh sebagai salah satu Protokol Pencegahan COVID-19, di mana setiap pegawai atau pengunjung yang datang ke Kantor Desa Sukapura harus mempunyai suhu tubuh normal atau di bawah 37,5oC. Namun akurasi pengukuran suhu masih bisa ditingkatkan dan bisa diterapkan pengukur suhu yang multi-person. Selain itu pegawai di Kantor Desa Sukapura juga perlu upgrading skill dan pengetahuan terkait penggunaan teknolologi untuk pengukuran suhu. Oleh karena itu pada Pengabdian kepada Masyarakat (PkM) Community Service Engagement (CSE) ini diusulkan untuk dilakukan pendampingan desa berupa perancangan dan implementasi Pemeriksaan Suhu Badan dengan Citra Termal Sesuai Protokol COVID-19 di Kantor Desa Sukapura. Selain itu agar pegawai dapat menggunakan teknologi tersebut dilakukan penyuluhan terkait penggunaan pemeriksaan suhu badan dengan citra termal sesuai protokol COVID-19 di Kantor Desa Sukapura.
