Abstract

Efficiency and effectiveness in controlling crossbreeding are pivotal in yielding superior hybrid varieties with desired traits such as genetic purity and high productivity. Cytoplasmic Male Sterile (CMS) is a crucial component in hybrid variety assembly. This study aims to identify the genotypes that can induce male sterile lines based on genetic diversity and the level of pollen sterility in the prospective male sterile genotypes tested, consisting of seventeen genotypes. The research findings revealed that the genetic diversity among the seventeen observed male-sterile candidate genotypes tends to vary in quantitative traits. Among the quantitative traits, JHD14 exhibited indications of being a male sterility inducer compared to the other genotypes observed, demonstrating a value of 0.00 g in terms of pollen weight. This is further substantiated by the microscopic examination of JHD14 pollen grains, which displayed 100% sterility.

Abstract

Kegiatan Program Pengembangan Usaha Produk Intelektual Kampus UNHAS (PPUPIK) ini bertujuan memproduksi benih jagung Sintetik Unhas (SINHAS-1) untuk mendukung pengembangan jagung pada lahan kering dan marginal, khususnya menghadapi cekaman kekeringan dan ketersediaan nitrogen rendah yang selama ini menjadi kendala utama dalam produksi jagung nasional Produksi benih dilaksanakan melalui tahapan produksi benih di Exfarm Fakultas Pertanian Universitas Hasanuddin dan lahan mitra di Kecamatan Bajeng, Kabupaten Gowa, selama Mei–Oktober 2025. Proses mengikuti Good Seed Production Practices (GSPP), meliputi isolasi varietas, pemeliharaan tanaman, roguing, panen, pengeringan hingga kadar air <12%, pembersihan menggunakan seed cleaner, sertifikasi, serta pengemasan sebelum distribusi kepada petani dan mitra terkait. Varietas SINHAS-1 menunjukkan mutu benih yang tinggi dengan kemurnian genetik ≥98% dan daya tumbuh >90%, sesuai SNI 01-6233-2000. Produktivitas mencapai 2,5 t/ha di musim kemarau dan tetap stabil pada kondisi cekaman abiotik. Harga benih Rp 15.000/kg sehingga lebih terjangkau dibanding benih hibrida (>Rp 100.000/kg). Implementasi program turut meningkatkan kapasitas mahasiswa dalam kewirausahaan benih, memperkuat fungsi Exfarm sebagai unit usaha benih kampus, dan memperluas akses petani terhadap benih unggul adaptif lahan marginal.    Kata kunci: SINHAS-1, lahan marginal, benih bersari bebas, toleransi cekaman, produksi benih.   ABSTRACT The UNHAS Campus Intellectual Product Development Program (PPUPIK) aims to produce Unhas Synthetic Corn Seeds (SINHAS-1) to support corn development on dry and marginal lands, particularly in the face of drought and low nitrogen availability, which have been major obstacles in national corn production. Seed production will be carried out through seed production stages at the Exfarm of the Faculty of Agriculture, Hasanuddin University, and partner fields in Bajeng District, Gowa Regency, from May to October 2025. The process follows Good Seed Production Practices (GSPP), including variety isolation, plant maintenance, roguing, harvesting, drying to a moisture content of <12%, cleaning using a seed cleaner, certification, and packaging before distribution to farmers and relevant partners. The SINHAS-1 variety demonstrates high seed quality with genetic purity ≥98% and germination rate >90%, in accordance with SNI 01-6233-2000. Productivity reaches 2.5 t/ha during the dry season and remains stable under abiotic stress conditions. The seed price is IDR 15,000/kg, which is more affordable than hybrid seeds (>IDR 100,000/kg). The implementation of the program also increases students' capacity in seed entrepreneurship, strengthens the function of Exfarm as a campus seed business unit, and expands farmers' access to adaptive superior seeds for marginal land.   Keywords: SINHAS-1, marginal land, open-pollinated seeds, stress tolerance, seed production.

Abstract

Statistical data shows that rice production increases every period along with the increase in demand. Harvested paddy must be dried immediately to avoid damage due to microbial attack that can live in high moisture content. Therefore, the main objective of drying is to reduce the moisture content from the harvest moisture content (23-27%) to a safe moisture content for storage (14%). Currently, there are several dryers made as a solution in post-harvest handling of grains such as green beans, soybeans, grain and so on. One example of this dryer is the Fluidized Bed Dryer. This tool is a mechanical dryer that can be used in drying grain. The advantage of this tool is that the temperature can be controlled and can produce quality and uniform drying results. The purpose of this study was to determine the drying characteristics of Inpari 42 grain using a fluidized bed dryer. This research method uses speed variations of 1.5 m/s, 2.0 m/s, and 2.5 m/s with sample masses of 200 g, 250 g and 300 g, using a temperature of 55 ℃. The research parameters include moisture content, drying rate, damaged grain. The drying process shows that the change in sample mass is influenced by the air velocity used. Along with the increase in moisture content, the drying rate will affect the rate of drying obtained in this study the drying rate pattern is decreasing. It can be concluded that air velocity affects the drying rate and air velocity affects the cracked grain.
