"Penelitian ini merupakan evaluasi performa LoRa dengan menggunakan arsitektur Simple Lora Protocol dengan frekuensi 433 MHz dan 915 MHz yang merupakan frekuensi ISM Band. Saat ini belum terlalu banyak yang mengadopsi teknologi LoRa di Indonesia. Namun dimasa depan nantinya akan banyak yang menggunakan teknologi LoRa dalam Internet of Things, seperti halnya smart city. Transmisi termodulasi LoRa kuat terhadap gangguan dan dapat diterima melintasi jarak yang jauh. LoRa sangat ideal untuk aplikasi yang mengirimkan ukuran data yang kecil, seperti data sensor yang memiliki bit rate rendah. Dalam hal ini, penulis melakukan evaluasi kinerja teknologi LoRa pada frekuensi 433 MHz dan 915 MHz dengan kondisi Line of Sight (LoS) dan Non-Line of Sight (Non-LoS) di lingkungan Universitas Indonesia. Parameter yang dievalusi, yaitu kekuatan sinyal (RSSI), Signal Noise Ratio (SNR), dan Delay. Perangkat prototipe ini disusun oleh sensor suhu dan kelembaban, modul LoRa sebagai transmitter dan receiver data yang dikirimkan, Arduino sebagai pengontrol rangkaian elektronika, dan Thingsboard yang merupakan cloud server untuk visualisasi data. Hasilnya menunjukan bahwa prototipe dapat berjalan dengan baik pada kedua kondisi. Pada frekuensi LoRa 433 MHz memiliki jangkauan sinyal hingga 350 meter pada kondisi LoS dan 150 meter pada kondisi Non-LoS. Sedangkan pada LoRa frekuensi 915 MHz memiliki jangkauan sinyal hingga 200 meter pada kondisi LoS dan 150 meter pada kondisi Non-LoS. Dengan demikian LoRa dengan frekuensi 433 MHz memiliki jangkauan sinyal yang lebih luas dibandingkan frekuensi 915 MHz. Selain itu terbukti Arsitektur Simple LoRa protocol dapat digunakan secara efisien untuk aplikasi IoT.

This research is an evaluation of LoRa performance using the Simple Lora Protocol architecture with frequencies of 433 MHz and 915 MHz which are the ISM Band frequencies. Currently, not many people have adopted LoRa technology in Indonesia. However, in the future, many will use LoRa technology in the Internet of Things, such as smart cities. LoRa modulated transmission is strong against interference and can be received over long distances. LoRa is ideal for applications that transmit small data sizes, such as sensor data at low bit rates. In this case, the authors evaluate the performance of LoRa technology at 433 MHz and 915 MHz frequencies with Line of Sight (LoS) and Non-Line of Sight (Non-LoS) conditions at the University of Indonesia. Parameters evaluated are signal strength (RSSI), Signal Noise Ratio (SNR), and delay. This prototype device consists of a temperature and humidity sensor, a LoRa module as a transmitter and receiver of transmitted data, Arduino as an electronic circuit controller, and Thingsboard which is a cloud server for visualizing data. The results show that the prototype can run well in the second condition. At 433 MHz LoRa frequency has a range of up to 350 meters in LoS conditions and 150 meters in Non-LoS conditions. While the LoRa frequency of 915 MHz has a range of up to 200 meters in LoS conditions and 150 meters in Non-LoS conditions. Thus LoRa with a frequency of 433 MHz has a wider range than the frequency of 915 MHz. In addition, it is proven that the Simple LoRa protocol architecture can be used efficiently for IoT applications."

"Process modeling style focuses on other aspects of process modeling beyond notation that are very important to practitioners. Many people who model processes focus on the specific notation used to create their drawings. While that is important, there are many other aspects to modeling, such as naming, creating identifiers, descriptions, interfaces, patterns, and creating useful process documentation. Experience author John Long focuses on those non-notational aspects of modeling, which practitioners will find invaluable."

"We conducted a finite element simulation by using a computer program, ATENA, to verify the behavior of T-section reinforced concrete beams strengthened by bonded wire ropes in the negative moment region with a pretensioned initial prestressing force; we compared this behavior with that in experimental tests. The simulation was performed on five models consisting of one unstrengthened beam and beams strengthened by wire ropes with initial prestressing forces of 0%, 10%, 20%, and 30%. We found that the capacity of a flexural load had the ratios to the experimental results close to 1 — that is, 1.25, 1.16, 1.12, 1.01, and 1.10, for UB, SB1, SB2, SB3, and SB4, respectively. The ratios of effective stiffness, as the result of the simulation, to the experimental results were 1.45, 1.08, 1.76, 2.13, and 2.46 for UB, SB1, SB2, SB3, and SB4, respectively. We also observed that crack propagation developed in the finite element simulation indicated that all models underwent flexural failure."

"PT XYZ adalah sebuah perusahaan yang bergerak dibidang teknologi keuangan. Didirikan pada tahun 2020, PT XYZ menghubungkan berbagai layanan yang disediakan oleh PT ABC sebagai induk perusahaan. Pengembangan perangkat lunak di PT XYZ dilakukan dengan menggunakan kerangka kerja Scrum. Dalam pelaksanaannya terjadi banyak keterlambatan penyelesaian Sprint, dimana dari 18 Sprint yang dijalankan pada tahun 2021, 10 diantaranya mengalami keterlambatan penyelesaian Sprint. Hasil identifikasi menunjukkan adanya masalah terkait dukungan organisasi dan kurangnya pemahaman terkait Scrum, yang mengindikasikan bahwa perusahaan dinilai belum siap mengimplementasikan Scrum. Penelitian ini bertujuan untuk menilai tingkat kesiapan organisasi dalam melakukan pengembangan perangkat lunak menggunakan kerangka kerja Scrum dan memberikan rekomendasi untuk meningkatkan kesiapan. Penelitian ini menggunakan Scrum Project Readiness Self-Assessment untuk menilai tingkat kesiapan organisasi terhadap pengembangan perangkat lunak menggunakan kerangka kerja Scrum. Dari hasil penelitian, didapatkan kesimpulan skor kesiapan organisasi dalam pengembangan perangkat lunak menggunakan kerangka kerja Scrum sebesar 67 dari maksimum 84. Organisasi dinyatakan siap dan dapat berhasil dalam mengimplementasikan Scrum, namun terdapat beberapa masalah yang harus diselesaikan untuk memastikan pengerjaan produk sesuai rencana. Masalah yang teridentifikasi yaitu pemahaman Scrum di organisasi masih kurang dan automation testing belum digunakan dalam instrumen pengujian. Berdasarkan masalah yang teridentifikasi, perusahaan direkomendasikan merekrut Scrum Master profesional untuk melatih organisasi dan menerapkan Test-Driven Development dalam melakukan pengembangan.

PT XYZ is a company engaged in financial technology. Established in 2020, PT XYZ connects various services provided by PT ABC as the parent company. Software development at PT XYZ is carried out using the Scrum framework. In its implementation, there are many delays in completing Sprints, where out of 18 Sprints carried out in 2021, 10 of them experienced Sprint completion delays. The results show that there are problems related to organizational support and a lack of understanding regarding Scrum, which indicates that the company is considered not ready to implement Scrum. This study aims to assess the level of organizational readiness in carrying out software development using the Scrum framework and provide recommendations to improve readiness. This study uses the Scrum Project Readiness Self-Assessment to assess the level of organizational readiness for software development using the Scrum framework. From the results of the study, the conclusion of the organizational readiness score in software development using the Scrum framework is 67 out of a maximum of 84. The organization is declared to be ready and can be successful in implementing Scrum, but there are several problems that must be resolved to ensure product work according to plan. The identified problems are that the understanding of Scrum in the organization is still lacking and automation testing has not been used in the testing instrument. Based on the problem, the company is recommended to recruit a professional Scrum Master to train the organization and apply Test-Driven Development in developing development."
