Judul: Designing and Building SAPIKU application as a website-based beef cattle management information system
Abstrak: Abstrak: Perkembangan teknologi digital di era Industri 4.0 saat ini telah membawa perubahan dan mempengaruhi berbagai aspek kehidupan manusia, termasuk bidang teknologi. Penerapan teknologi ini dapat diterapkan pada perkembangan teknologi peternakan salah satunya sapi pedaging. Kondisi peternakan saat ini dikelola secara manual dan kurang efisien. Dalam prakteknya masih banyak peternak yang kurang baik dalam hal pengelolaan peternakan sapi yang mereka miliki. Penelitian ini bertujuan untuk membangun aplikasi SAPIKU sebagai sistem informasi berbasis website yang berfungsi membantu peternak dalam mengelola peternakan sapi pedaging. Pendekatan tahap perancangan sistem informasi menggunakan metode pengembangan System Development Life Cycle (SDLC). Adanya manajemen yang baik pada peternakan sapi pedaging dapat membantu peternak atau industri peternakan untuk mencapai tujuan yang diinginkan secara efisien. Sistem informasi manajemen yang dibangun akan fokus pada pendataan populasi sapi pedaging, pekerja, kandang, monitoring perkembangan sapi, manajemen keuangan (penjualan dan pengeluaran) serta manajemen pakan. Abstract: Technological developments in the digital era of Industry 4.0 have now brought changes and influenced various aspects of human life, including the field of technology. The application of this technology can be applied to the development of livestock technology, one of which is beef cattle. The current condition of the farm is managed manually and less efficiently. In practice, there are still many breeders who are not good at managing their cattle farms. This study aims to build the SAPIKU application as a website-based information system that functions to help breeders in beef cattle farming organizations. The approach to the information system design stage uses the System Development Life Cycle (SDLC) development method. Good management of beef cattle farms can help breeders or the livestock industry to achieve the desired goals efficiently. The management information system that is built will focus on data collection of beef cattle population, workers, pens, monitoring of cattle development, financial management (sales and expenses) and feed management.

Judul: Implementation of Scrum for Development of REST API-Based Digital Cattle Registration System
Abstrak: Efektivitas manajemen dalam industri peternakan sapi diperlukan dalam mengatasi ketidakseimbangan antara kebutuhan dan produksi daging sapi di Indonesia. Salah satu permasalahan utama yang dihadapi adalah tidak adanya standarisasi sistem pencatatan ternak untuk memberikan informasi yang valid mengenai perkembangan ternak. Penelitian yang telah dilakukan oleh Basyir (2023) berhasil mengembangkan sistem registrasi bagi pendataan ternak sapi. Penelitian ini bertujuan mengembangkan sistem pencatatan ternak sapi yang lebih komprehensif dan terpusat. Penelitian ini dilakukan dengan metode Scrum, yang meliputi product backlog, sprint planning, daily scrum meeting, sprint review, dan sprint retrospective sebagai tahapannya. Sistem diuji melalui serangkaian sprint, dengan setiap sprint berfokus pada pengembangan dan penyempurnaan API untuk kategori user, cage, livestock, note, bcs, dan dashboard, serta deployment menggunakan Google Cloud Platform (GCP). Hasil pengujian blackbox testing menunjukkan semua test cases berhasil dan sesuai dengan ekspektasi. Sistem ini juga diuji menggunakan load testing dengan hasil yang baik sesuai dengan parameter yang diujikan yaitu throughput, response time, dan error rate., Management effectiveness in the cattle industry is needed to address the imbalance between beef demand and production in Indonesia. One of the main problems faced is the absence of a standardized livestock registration system to provide valid information on livestock development. Research conducted by Basyir (2023) successfully developed a registration system for cattle data collection. This research aims to develop a more comprehensive and centralized cattle recording system. This research was conducted using the Scrum method, which includes product backlog, sprint planning, daily scrum meeting, sprint review, and sprint retrospective as its stages. The system was tested through a series of sprints, with each sprint focusing on developing and refining APIs for the user, cage, livestock, note, bcs, and dashboard categories, as well as deployment using Google Cloud Platform (GCP). The results of blackbox testing showed that all test cases were successful and in line with expectations. The system was also tested using load testing with good results according to the parameters tested, namely throughput, response time, and error rate.

Judul: Sintesis 3-Benzoil-7-hidroksiflavon dari Resorsinol
Abstrak: Flavonoid is the most abundant naturally-occuring polyphenolic compound with C6-C3-C6 carbon skeleton. Flavones is a group of flavonoid having a broad bioactivity spectrum. In this experiment, 3-benzoyl-7-hydoxyflavone was successfully synthesized via 2-steps from resorcinol. In the first step, resorcinol was acetylated with AcOH/ZnCl2 producing resacetophenone with 89% yield. Subsequently, benzoylation and rearrangement of resacetophenone using 2 equivalent of benzoyl chloride and 7 equivalent of K2CO3 in acetone produced 3-benzoyl-7-hydroxyflavone with 62% yield. Synthesis of 3-benzoyl-7-hydroxyflavone from resorcinol provided evidence for new reaction mechanism of flavon formation without Baker-Venkataraman rearrangement proposed by several previous researchers. All products in this study has been characterized spectroscopically.
