Judul: Development of a Real-Time Machine Condition Monitoring System Using Internet of Things on Hot Press Machine at PT. XYZ
Abstrak: The increasingly high competition makes companies have to continue improving the productivity of existing production. One of the efforts can be made by improving the performance of the production facilities, such as machines and other supporting equipment. Human limitations in monitoring machine performance are factors in handling slow production processes. This factor causes no measurement of machine performance at any time and the risk of sudden machine damage. This project aims to design a real-time machine condition monitoring system using Internet of Things (IoT) technology and Overall Equipment Effectiveness (OEE) performance methods. The project is carried out using the method of engineering design stages. Based on the test results, the prototype designed can receive and send machine condition data to cloud services which are then integrated into mobile applications with the results of machine data visualization, namely availability, performance, quality, OEE, temperature, and vibration.

Judul: Design of a Real-Time Temperature and Meat Quality Monitoring System Based on Internet of Things during Distribution at PT XYZ
Abstrak: Agroindustri memiliki peran penting dalam mengolah hasil produk pertanian, termasuk daging sapi yang memiliki nilai ekonomi tinggi namun mudah rusak. Untuk menjaga kualitas daging sapi selama distribusi, PT XYZ menghadapi tantangan dalam pengawasan suhu dan kualitas produk. Penelitian ini bertujuan merancang sistem monitoring suhu dan kualitas daging secara real-time menggunakan teknologi Internet of Things (IoT) untuk mengatasi permasalahan tersebut. Metode penelitian mencakup eksplorasi masalah, pendefinisian masalah, ideasi solusi, pengembangan prototipe, serta uji dan validasi sistem. Pada tahap eksplorasi, ditemukan bahwa fluktuasi suhu selama distribusi menyebabkan kerusakan produk. Oleh karena itu, solusi yang diusulkan adalah implementasi IoT untuk pemantauan suhu dan kualitas secara real-time. Prototipe yang dirancang terdiri dari perangkat keras seperti mikrokontroler, sensor suhu, dan modul Wi-Fi, serta perangkat lunak berbasis web untuk menampilkan data. Pengujian perangkat keras menunjukkan bahwa sensor memiliki tingkat kesalahan yang dapat diterima, sementara perangkat lunak berhasil menampilkan data suhu dan kualitas (TVB) serta grafik selama distribusi. Hasil penelitian menunjukkan bahwa sistem monitoring suhu dan kualitas daging berbasis IoT dapat meningkatkan efektivitas dan efisiensi rantai pasok dingin di PT XYZ. Sistem ini mampu mengurangi kerusakan produk dengan pemantauan real-time, meningkatkan kepuasan pelanggan dan daya saing perusahaan., The agro-industrial sector plays an important role in processing agricultural products, including beef, which has high economic value but is highly perishable. To maintain beef quality during distribution, PT XYZ faces challenges in monitoring temperature and product quality. This study aims to design a real-time temperature and quality monitoring system for beef using Internet of Things (IoT) technology to address these challenges. The research methodology includes problem exploration, problem definition, solution ideation, prototype development, and system testing and validation. During the exploration phase, it was found that temperature fluctuations during distribution cause product damage. Therefore, the proposed solution is the implementation of IoT for real-time temperature and quality monitoring. The designed prototype consists of hardware such as a microcontroller, temperature sensor, and Wi-Fi module, as well as web-based software to display the data. Hardware testing showed that the sensors have an acceptable error rate, while the software successfully displayed temperature and quality (TVB) data and graphs during distribution. The research results indicate that the IoT-based temperature and quality monitoring system can improve the effectiveness and efficiency of the cold supply chain at PT XYZ. This system can reduce product damage with real-time monitoring, increasing customer satisfaction and the company's competitiveness

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
