Judul: Immersive Analytics Module Prototype for Wireless Sensor Data Visualization of i-Surf Lab IPB University Using Unity 3D Engine
Abstrak: Sistem visualisasi data Laboratorium i-Surf yang ada pada saat ini pada dasarnya belum mengimplementasikan immersive analytics (IA) untuk membantu proses analisis. Pengembangan sistem visualisasi data yang akan dikembangkan bersifat immersive dan diharapkan dapat membantu proses analisis terhadap data dengan menggunakan virtual reality (VR) dan menjadi wadah untuk mahasiswa ataupun peneliti sebagai pengelola i-Surf dalam menganalisis data secara immersive. Pengembangan sistem ini berfokus pada pembuatan modul visualisasi data dengan menggunakan teknologi VR untuk dilakukan analisis secara immersive pada data sensor nirkabel i-Surf Lab. Pengembangan modul diharapkan dapat memunculkan grafik data secara real time. Pengembangan sistem akan dilakukan dengan menggunakan Unity3D Engine (UE). Hasil pengembangan modul IA untuk visualisasi data sudah berhasil dikembangkan dan mendapatkan penilaian yang baik pada tahap pengujian modul., Basically, the existing i-Surf Laboratory data visualization system has not implemented immersive analytics (IA) to assist in the analysis process. The development of the data visualization system that will be developed is immersive and is expected to help the data analysis process using virtual reality (VR) and become a forum for students or researchers as i-Surf managers in analyzing data immersive. The development of this system focuses on creating a data visualization module using VR technology for immersive analysis of the i-Surf Lab wireless sensor data. The development of the module is expected to be able to display data graphs in real-time. The system development will be carried out using the Unity3D Engine (UE). The results of the development of the IA module for data visualization have been successfully developed and have received good ratings at the module testing stage.

Judul: Development of Virtual Reality for  Immersive Learning in the Greenhouse of IPB Campus
Abstrak: Virtual reality atau VR adalah teknologi next-generation yang memungkinkan pengguna untuk mendapatkan pengalaman virtual yang sangat realistis dan mendalam. Menggunakan konsep VR dan fitur yang memungkingkan penggunanya berinteraksi seperti di dunia nyata terlihat efektif untuk meningkatkan ketertarikan terhadap berbagai bidang, terutama sektor agrikultur yang semakin sepi akan peminat. Pada penelitian ini, peneliti akan merancang aplikasi berteknologi VR interaktif berlatar Greenhouse I-Surf IPB sebagai pembelajaran imersif pada bidang agrikultur terhadap pelajar. Penelitian ini dikembangkan menggunakan Unity dan dieksekusi menggunakan perangkat Oculus Quest 2 yang terbagi menjadi 4 fase pengembangan dengan metode game development life cycle (GDLC) yaitu initiation, production, pre-production, dan testing. Pengguna dapat menjelajahi I-Surf bersama mekanik permainan berupa mencari peralatan pertanian dan juga menumbuhkan tanaman secara sederhana. Aplikasi berhasil dikembangkan dan berhasil melewati Testing menggunakan metode black-box tanpa adanya masalah teknis maupun terkait perangkat VR terhadap aplikasi yang dikembangkan, sehingga menunjukkan potensi pengembangan sektor pembelajaran menggunakan teknologi VR kedepannya, Virtual reality is a next-generation technology that allows users to experience highly realistic and immersive virtual environments. Utilizing the concept of VR that simulates real-world interactions appears to be effective in generating interest in various fields, particularly the agriculture sector. In this research, the researcher will design an interactive VR application based on I-Surf IPB Greenhouse as an immersive learning tool for agriculture among students. The research will be developed using Unity with Oculus Quest 2 device. There are four development phases: initiation, production, pre-production, and testing, following a simplified version of the game development life cycle (GDLC). Users can explore I-Surf with gameplay mechanics such as searching for farming equipment and growing plants in a simple manner. The application has been successfully developed and passed the black-box testing without any technical issues or problems related to the VR device and the developed application. This demonstrates the potential for future development of the education sector using VR technology.

Judul: Insecticidal Activity of Essential Oils Leaves of Cinnamomum spp. (Lauraceae) against Crocidolomia pavonana and Their Phytotoxicity on Broccoli Seedlings
Abstrak: Essential oils from leaves of 13 species of Cinnamomum were tested for their insecticidal activity on the cabbage head caterpillar Crocidolomia pavonana with leaf immerse method. The results showed that the treatment with 1% (w/v) essential oils leaves of C. celebicum, C. multiflorum, C. sintoc, and C. verum caused 21.45, 93.65, 60.30, and 76.10% mortality, respectively. Based on the results of phytotoxicity and insecticidal activity tests, C. multiflorum oil was further tested at 6 concentration levels. In all treatments, larval mortality has occurred at 24 hours after treatment (HAT) and increased at 48 HAT. LC50 of C. multiflorum oil at 24 and 48 HAT was 0.504 and 0.396%, respectively. The treatment with C. multiflorum oil at ≤0.31% did not inhibit the development of C. pavonana larvae. Determination of the chemical constituents of Cinnamomum oils were carried out by gas chromatography-mass spectrometry (GCMS). Totally, 345 compounds were identified. Methyleugenol constituted the main component (49.4%) of leaf essential oil of C. multiflorum and was assumed to be responsible for the insecticidal activity of the oil against C. pavonana larvae. LC50 of pure methyleugenol obtained at 0.365% (48 HAT) and 0.363% (72 HAT). The results showed that C. multiflorum was more effective with LC50 value equivalent to methyleugenol content of 0.32% (24 HAT) and 0.24% (48 HAT).
