Abstract

Genetic diversity, heritability, and trait relationships are essential parameters for identifying selection criteria and improving maize productivity across diverse growing environments. This study aimed to evaluate genetic diversity, broad-sense heritability, and correlations among agronomic and yield-related traits of hybrid maize cultivated under two contrasting topologies. Field experiments were conducted using hybrid maize genotypes, and data were analyzed through variance component estimation, heritability analysis, and Pearson correlation coefficients. The results showed that phenotypic variance was generally greater than genotypic variance for most traits, indicating a considerable contribution of environmental factors to trait expression. High heritability values were observed for ear height, leaf width, number of kernels per ear, ear length, ear diameter, and shelling percentage, whereas leaf length, moisture content, kernel row number, and thousand-kernel weight exhibited moderate heritability. All observed traits displayed narrow genetic variability, suggesting limited genetic divergence among the evaluated hybrids. Grain yield was positively associated with fresh ear weight, ear length, ear diameter, number of kernels per ear, leaf length, and stem diameter, while flowering time and several vegetative traits tended to show negative associations with yield. Fresh ear weight showed the strongest relationship with grain yield, indicating its importance as a yield-related trait. These findings demonstrate that ear-related characters can be used as reliable indirect selection criteria for yield improvement in hybrid maize.

Abstract

Kebun Smart Exfarm Fakultas Pertanian Universitas Hasanuddin dikembangkan sebagai unit produksi sayuran sekaligus wahana pembelajaran lapangan bagi mahasiswa. Pengelolaan kebun yang berkelanjutan memerlukan sumber daya manusia yang memiliki pengetahuan dan keterampilan dalam budidaya, pengelolaan kebun, dan pemasaran hasil. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kapasitas pengelola Kebun Smart Exfarm melalui pelatihan dan pendampingan budidaya serta manajemen produksi sayuran. Kegiatan dilaksanakan menggunakan pendekatan partisipatif berbasis capacity building melalui empat tahap, yaitu identifikasi kondisi awal, pelatihan dan praktik, pendampingan, serta monitoring dan evaluasi. Peserta pelatihan adalah pengelola Kebun Smart Exfarm, meliputi anggota UKM Smart Farmers dan mahasiswa magang yang berasal dari Program Studi Agroteknologi Fakultas Pertanian. Materi kegiatan mencakup budidaya sayuran secara hidroponik, budidaya dan pemeliharaan tanaman khususnya sistem raised bed, serta manajemen pengelolaan kebun dan pemasaran hasil. Evaluasi perubahan pengetahuan dilakukan terhadap 37 peserta menggunakan pre-test dan post-test. Hasil kegiatan menunjukkan peningkatan nilai pengetahuan rata-rata dari 81,80 menjadi 96,04 atau sebesar 17,40%. Peningkatan terbesar terjadi pada pengetahuan budidaya hidroponik sebesar 30,66%, diikuti manajemen kebun dan pemasaran sebesar 21,58%. Pendampingan juga memberikan pengalaman kepada peserta dalam menerapkan teknologi raised bed dan hidroponik hingga pengelolaan dan pemasaran hasil. Kegiatan capacity building mampu meningkatkan pengetahuan peserta dan memperkuat proses pembelajaran berbasis praktik dalam pengelolaan Kebun Smart Exfarm. Keberlanjutan kegiatan perlu didukung melalui standardisasi produksi dan penjualan serta pendampingan secara berkala. Kata kunci: Capacity building, Hidroponik, Pengelolaan kebun, Raised bed, Sayuran, Smart Exfarm. ABSTRACT Smart Exfarm at the Faculty of Agriculture, Hasanuddin University, has been developed as a vegetable production unit as well as a field-based learning facility for students. Sustainable farm management requires human resources with adequate knowledge and skills in crop cultivation, farm management, and product marketing. This community engagement program aimed to strengthen the capacity of Smart Exfarm managers through training and mentoring in vegetable cultivation and production management. The program employed a participatory capacity-building approach consisting of four stages: initial condition assessment, training and hands-on practice, mentoring, and monitoring and evaluation. Participants were Smart Exfarm managers, including members of the Smart Farmers Student Activity Unit and interns from Agrotechnology Study Program, Faculty of Agriculture. The program covered hydroponic vegetable cultivation, vegetable cultivation and crop maintenance with particular emphasis on raised-bed systems, as well as farm management and product marketing. Changes in participants’ knowledge were evaluated among 37 participants using pre- and post-tests. The results showed that the mean knowledge score increased from 81.80 to 96.04, representing a 17.40% improvement. The greatest improvement was observed in hydroponic cultivation knowledge (30.66%), followed by farm management and product marketing (21.58%). The mentoring activities also provide participants with hand-on experience in applying raised-bed and hydroponic cultivation technologies, as well as in farm management and product marketing. The capacity-building program improved participants’ knowledge and strengthened practice-based learning in Smart Exfarm management. The sustainability of the program should be supported through standardized production and sales management and periodic mentoring. Keywords: Capacity building, Farm management, Hydroponics, Raised bed, Smart Exfarm, Vegetable.

Abstract

Saat ini pemerintah Kota Makassar menggalakkan program urban farming bagi masyarakat di tingkat RT/RW di setiap kelurahan. Program tersebut bertujuan untuk meningkatkan ketahanan pangan masyarakat secara mandiri. Kelompok Wanita Tani (KWT) yang terbentuk di setiap kelurahan juga diminta berperan aktif menghasilkan produk-produk pertanian seperti sayur-sayuran dan buah-buahan. Namun, tanah-tanah di perkotaan umumnya tidak subur karena aktivitas manusia, timbunan bahan bangunan, dan cemaran-cemaran lain dari limbah rumah tangga, industri, rumah sakit, dan pabrik-pabrik. Media tumbuh DAENGKU menawarkan solusi tepat bagi penggiat pertanian perkotaan untuk meningkatkan kesuburan tanah perkotaan. Selain itu, dengan semakin sulitnya ketersediaan tanah subur di perkotaan, maka DAENGKU diharapkan mampu menyediakan media tumbuh yang baik dan memberikan keuntungan ekonomi bagi mitra. Kegiatan Program Pengabdian kepada Masyarakat UNHAS-Program Pengembangan Usaha Produk Intelektual Kampus (PPMU-PPUPIK) ini bertujuan meningkatkan pengetahuan, wawasan, dan keterampilan mitra mengelola dan menghasilkan media tanam DAENGKU. Kegiatan pengabdian ini berlangsung sejak April-Juni 2026 di KWT Selasih, Kelurahan Bangkala, Kecamatan Manggala, Kota Makassar. Kegiatan ini berhasil meningkatkan pengetahuan dan keterampilan mitra sasaran tentang pengelolaan limbah organik dan eceng gondok dengan teknologi mikroba biodekomposer. Hasil pre-post test menunjukkan lebih 85% dari anggota KWT mengalami peningkatan wawasan dan pengetahuan terkait kegiatan ini. Selain itu, KWT Selasih juga telah berhasil memproduksi dan menjual DAENGKU di toko-toko pertanian, pameran, dan online sekitar 500-600 kg per bulan. Informasi kegiatan ini juga telah tersebar melalui media online dan kanal Youtube Fakultas Pertanian. Kata kunci: Kelompok Wanita Tani, Kompos, Mikroba, Pertanian perkotaan, Sayuran. ABSTRACT The Makassar City government is currently promoting urban farming programs for residents at the neighborhood (RT/RW) level in every urban village (*kelurahan*). These programs aim to enhance community food security through self-reliance. Women Farmers' Groups (KWT) established in each village are also encouraged to play an active role in producing agricultural goods such as vegetables and fruits. However, urban soil is generally infertile due to human activity, construction debris, and contamination from household, industrial, hospital, and factory waste. DAENGKU growing medium offers an ideal solution for urban farming enthusiasts looking to improve urban soil fertility. Furthermore, given the increasing scarcity of fertile urban land, DAENGKU is expected to provide a high-quality growing medium while generating economic benefits for its partners. This UNHAS Community Service and Campus Intellectual Product Business Development Program (PPMU-PPUPIK) aimed to enhance the knowledge, insight, and skills of partners in managing and producing the DAENGKU growing medium. The program was conducted from April to June 2026 with the Selasih Women Farmers' Group (KWT) in Bangkala Village, Manggala District, Makassar City. The initiative successfully improved the target partners' knowledge and skills regarding the management of organic waste and water hyacinth using microbial biodecomposer technology. Pre- and post-test results indicated that over 85% of KWT members gained increased insight and knowledge related to the program. Additionally, KWT Selasih has successfully produced and sold DAENGKU—through agricultural shops, exhibitions, and online channels—at a volume of approximately 500–600 kg per month. Information regarding this program has also been disseminated via online media and the Faculty of Agriculture's YouTube channel. Keywords: Compost, Microbe, Urban farming, Vegetables, Women Farmer Groups.
