Judul: Immersive Tour Farm: Development of Virtual Farm Tours to Enhance Youth Engagement in Agriculture
Abstrak: Penelitian ini dilakukan dalam konteks penurunan jumlah angkatan kerja pada sektor pertanian di Indonesia dari tahun 2014 hingga 2019, terutama di kalangan petani muda. Penurunan ini disebabkan oleh ketidaksesuaian keterampilan, pendapatan yang lebih tinggi di luar sektor pertanian, kurangnya edukasi, persepsi negatif, keterbatasan lahan, dan kurangnya integrasi antara komunitas pertanian dengan masyarakat umum. Dari permasalahan ini, solusi dapat mengacu pada penerapan desa digital yang memanfaatkan teknologi digital untuk meningkatkan berbagai aspek di desa. Selain itu, terdapat teknologi virtual reality (VR) yang dapat dimanfaatkan untuk meningkatkan output pembelajaran dengan menghadirkan pengalaman yang imersif. Oleh karena itu, penelitian ini dilakukan untuk memanfaatkan teknologi VR dalam bentuk tur pertanian virtual yang imersif untuk mempersiapkan mahasiswa ilmu komputer dari IPB University sebelum terlibat dalam kegiatan di pedesaan. Tur pertanian virtual yang dikembangkan dalam penelitian ini menyediakan informasi desa digital suatu area pertanian melalui artikel, foto, dan video. Dengan adanya tur pertanian ini, diharapkan dapat membantu generasi muda dalam mengenal desa digital, serta memotivasi mereka untuk terlibat dalam sektor pertanian di Indonesia. Hasil pengujian kelayakan fitur tur pertanian ini mengungkap bahwa fitur-fitur yang telah dibangun dapat berjalan dengan baik. Namun, hasil pengujian ini juga mengungkap catatan yang perlu diperhatikan terkait kenyamanan pengguna dan konten yang tersedia., This study examines the decline in agricultural employment in Indonesia between 2014 and 2019, specifically among young farmers. The decrease can be attributed to skill mismatch, higher incomes outside the agricultural sector, limited education, negative perceptions, land limitations, and a lack of integration between the farming community and the wider society. To tackle these challenges, implementing digital villages that utilize digital technology to enhance various aspects of rural areas is considered a potential solution. Additionally, virtual reality (VR) technology can be utilized to enhance learning outcomes by providing immersive experiences. Consequently, this research aims to leverage VR technology through the development of an immersive virtual farming tour, preparing computer science students from IPB University before their engagement in rural activities. The virtual farming tour created in this study delivers information about digital villages in agricultural regions through articles, photos, and videos. It is anticipated that this farming tour will facilitate the younger generation in understanding digital villages and inspire their involvement in the agricultural sector in Indonesia. The feasibility testing of the virtual farming tour features revealed that the built-in features function well. However, the testing results also highlighted some considerations regarding user comfort and available content.

Judul: Kajian Literatur Sistematik Penggunaan Teknologi Virtual Reality dalam Implementasi Pembelajaran Pertanian dan Perikanan
Abstrak: Studi ini menganalisis penelitian sebelumnya mengenai aplikasi untuk pembelajaran pertanian dan perikanan. Metode penelitian yang digunakan adalah kajian literatur sistematis dengan menggunakan Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Hasil penelitian menunjukkan bahwa materi pembelajaran dan desain elemen metaverse masih belum optimal. Masih terdapat celah implementasi antara teknologi imersif yang sedang dikembangkan saat ini dengan konsep metaverse. Oleh karena itu, perencanaan jangka panjang dan studi kasus penggunaan metaverse dalam pendidikan harus dilakukan lebih baik atau lebih matang lagi. Kekurangan ini menjadi poin penting untuk penelitian selanjutnya dalam pengembangan metaverse untuk pendidikan di bidang pertanian dan perikanan. Peneliti berharap studi ini mampu memberikan pengetahuan tentang teknologi metaverse kepada pendidik agar dapat membuat keputusan yang lebih tepat dalam memanfaatkannya di lembaga pendidikan., This study analyzes previous research regarding applications for learning agriculture and fisheries. The research method used is a systematic literature review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The research results show that the learning materials and metaverse element design are still not optimal. There is still an implementation gap between the immersive technology currently being developed and the metaverse concept. Therefore, long-term planning and case studies on the use of metaverse in education must be done better or more maturely. This deficiency is an important point for further research in developing a metaverse for education in agriculture and fisheries. Researchers hope that this study is able to provide knowledge about metaverse technology to educators so they can make more informed decisions in utilizing it in educational institutions.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
