Software-defined networking (SDN) technology is one key technology in telecommunications networks that are currently widely studied. In SDN-based networks, the controller holds the key to the reliability of a network because all control functions are held by the controller as one of the open-source controllers, the Open Network Operating System (ONOS) has two forwarding mechanisms, namely reactive forwarding, and proactive forwarding. This study compares performance between reactive forwarding and proactive forwarding on ONOS with VM migration as traffic. The parameter measured is the total migration time using simple network topology. From the test results, the proactive forwarding scenario can optimize the fastest potential of the topology tested by using the path that has the largest bandwidth available on the network topology. In comparison, reactive forwarding can only pass through the smallest hops of the tested topology. From the measurement results, the average migration time performance using a proactive forwarding scenario is 36.16% faster than the reactive forwarding scenario.

ABSTRACTInternet of Things (IoT) is one of the technological paradigms developed in the industrial revolution 4.0. The concept of IoT is an object can transfer data over a network without interaction from human-to-human or from human-to-computer. One of the IoT implementations in the education sector is the attendance system using IoT-based Radio Frequency Identification (RFID). The attendance machines such as fingerprints and face recognition have a relatively high-cost compared to RFID machines. Hence, if the number of attendance machines within the School is limited, it will be less efficient for a large number of students and vulnerable to queuing. The RFID implementation in the Education sector was socialized through a Workshop with students and teachers of the secondary schools in Purwakarta, West Java, as the participants. To provide additional insight and expertise about the RFID-IoT concept to the workshop participants, this community service activity needs to be done. Several benefits will be obtained through this workshop, including saving paper use and efficiency, because the RFID-based IoT can reduce the teachers’ workload in processing the student attendance lists. Teachers are also invited to this workshop so they can guide their students and pass on the additional skills. Moreover, the invited teacher will teach new knowledge related to workshop material to other students in the School.Keywords: Internet-of-things, RFID, Mesin Kehadiran, Workshop, Purwakarta ABSTRAKInternet of Things (IoT) merupakan salah satu paradigma teknologi yang dikembangkan dalam revolusi industri 4.0. Konsep IoT adalah suatau objek dapat mentransfer data lewat jaringan tanpa adanya interaksi dari manusia ke manusia ataupun dari manusia ke perangkat komputer. Salah satu implementasinya pada bidang pendidikan yaitu sistem kehadiran menggunakan Radio Frequency Identification (RFID) berbasis teknologi IoT. Mesin kehadiran seperti fingerprint dan face recognition memiliki harga yang relatif mahal dibandingkan mesin RFID. Sementara, jika jumlah mesin kehadiran yang ada di sekolah terbatas, hal ini sedikit kurang efisien untuk jumlah siswa yang sangat banyak dan rentan menimbulkan antrian. Implementasi RFID di bidang Pendidikan ini disosialisasikan melalui sebuah Workshop dengan siswa dan Guru dari sekolah menengah di Purwakarta, Jawa Barat sebagai peserta. Untuk dapat memberikan tambahan wawasan dan keterampilan mengenai mesin kehadiran RFID dengan konsep IoT kepada peserta Workshop, maka pengabdian masyarakat ini perlu dilakukan. Beberapa manfaat akan didapat memalui workshop ini, termasuk menghemat penggunaan kertas dan efisiensi karena RFID berbasis IoT mengurangi beban kerja guru dalam mengolah data kehadiran siswa.

Persediaan dalam kegiatan operasional perusahaan sangatlah penting perananya, oleh sebab itu diperlukan manajamen dan metode yang tepat dalam perhitungan persediaan. Sehingga penentuan kebijakan untuk memilih salah satu metode akuntansi yang tepat bagi perusahaan sangat diperlukan dalam proses pengendalian persediaan. Kepentingan yang terdapat pada manajemen, pemilik perusahaan dan pemerintah dalam penentuan metode akuntansi persediaan akan menimbulkan konflik karena masing-masing metode memiliki hasil ekonomi yang berbeda. Tujuan dari penelitian ini adalah untuk mengetahui apa saja faktor-faktor yang mempengaruhi pemilihan metode akuntansi persediaan yaitu ukuran perusahaan, variabilitas persediaan, variabilitas harga pokok penjualan dan laba sebelum pajak. Penelitian ini mengambil populasi dari perusahaan yang terdatar di Bursa Efek Indonesia di sub sektor perdagangan besar dan perdagangan eceran pada periode 2016-2019. Sampel penelitian diambil sebanyak 43 perusahaan dengan metode purposive sampling. Teknik yang digunakan yaitu regresi logistik untuk analisis pengaruh antara variabel independen dengan dependen. Hasil dari penelitian secara simultan variable independen mempengaruhi variable dependen. Secara parsial ukuran perusahan dan laba sebelum pajak tidak berpengaruh terhadap pemilihan metode akuntansi persediaan. Sedangkan variabilitas persediaan dan variabilitas harga pokok penjualan secara parsial berpengaruh signifikan.

Cataract, a condition characterized by clouding of the eye's lens, leads to decreased vision and potentially blindness. In Indonesia, it is the predominant cause of blindness, accounting for 81.2% of cases. Given the rising life expectancy, the incidence of degenerative diseases like cataracts is expected to increase. This research aims to develop a cataract detection system capable of classifying eye images as either indicative of cataracts or normal. Utilizing Convolutional Neural Networks (CNN) and RGB-based image processing—including edge detection techniques such as Canny and Prewitt—the system identifies eye contours. This facilitates image segmentation to ascertain the eye's condition. Therefore, image collection and processing models play a crucial role in this study. The research findings indicate that the system functions effectively, with a 98% success rate in accurately processing normal eye images through the CNN model without detecting cataracts. When tested using grayscale imaging, cataract-afflicted eyes—characterized by red spots in the images—were also successfully identified by the CNN model. These test results demonstrate that the designed cataract detection system can accurately classify images into normal or cataract-afflicted eyes with high precision. This system shows promise for use in early cataract detection, potentially helping to reduce the prevalence of cataract-related blindness in Indonesia.

Cloud infrastructure providers such as GCP provide various computing services to deploy applications such as machine learning models, namely server-based and serverless. However, the two services each have different characteristics and advantages so that this becomes a difficulty factor for users in choosing cloud services. This research was conducted to compare server-based and serverless services with the aim of knowing the best service resulting from the analysis of performance measurements, namely CPU and memory utilization, latency, pricing, and developer experiences. The application of machine learning models is carried out on Compute Engine and Vertex AI services and will be tested for performance through requests to endpoints 100 times using JMeter for 30 minutes. The findings show that Vertex AI performance is better than Compute Engine with CPU utilization of 0.10%, memory utilization of 0.94%, and latency of 17.34ms but the cost efficiency is owned by the Compute Engine.
