Shallots (Allium cepa var. aggregatum) is one of the vegetable commodities whose demand continues to increase in line with population growth. The purpose of this community service program to disseminate the results of research on how to produce true seed of shallot (TSS) then plant TSS to produce mini bulbs as seeds of shallots. The target audience was the farmers group Tani Mulya in Tawangargo Village, Karangploso Sub-District, Malang Regency, East Java. Activities step included preparation, socialization, demonstration plot of shallot bulbs planting to produce TSS and planting TSS, to produce mini bulbs as seeds of shallot. Batu Ijo variety grown to produce TSS, while planting of TSS used Tri Sula and Keta Monca varieties. This activitity was done well according to a Likert scale of 4.3 (good category = 4–4.9). Farmers were able to adopt the technology of TSS production and planting of TSS to produce shallot mini bulbs of seeds, with indication of the production of TSS and mini bulbs. The flowering of shallot plants 55.5 and TSS seed weight 10.16 g/m2. Bulbs seed of Batu Ijo variety produced large bulbs, while TSS from Tri Sula and Keta Monca varieties produced mini bulbs that can be used as seeds. The change of the shallot seeds technology from bulbs to TSS will be economically beneficial, because the TSS required less than bulbs, so the cost difference is quite large. TSS needs 3–5 kg/ha (TSS price IDR 1.200.000/kg), and bulbs seed needs 1–1.5 ton/ha (bulbs price IDR 30.000/kg), so the margin is IDR 24.000.000 per hectare.

ABSTRAKMutasi adalah satu cara untuk meningkatkan keragaman genetik dalam pemuliaan tanaman sehingga sifat yang dituju lebih mudah diperoleh. Biji dari tiga varietas jagung (Bisma, lokal Madura, dan Gumarang) diradiasi dengan sinar gamma 60 cobalt (dosis 0, 100, 200, dan 300 Gy) kemudian ditanam dalam rancangan petak terbagi dengan rancangan acak kelompok yang diulang tiga kali untuk dievaluasi karakter morfologi dan agronominya. Petak utama adalah varietas dan sebagai anak petak adalah dosis radiasi sinar gamma. Tidak terjadi interaksi nyata antara dosis sinar gamma dengan varietas jagung, namun peningkatan dosis sinar gamma menyebabkan penurunan beberapa sifat. Beberapa karakter seperti tinggi tanaman dan jumlah daun menurun secara nyata ketika dosis sinar gamma meningkat dari 100 menjadi 300 Gy, demikian juga komponen hasil seperti berat biji per tanaman dan jumlah biji per tongkol. Gamma 200 menghasilkan lebih banyak tongkol dibandingkan dosis yang lain. Varietas Bisma menunjukkan penampilan yang lebih baik dibandingkan Gumarang dan lokal Madura baik untuk sifat morfologi dan agronomi. Kata kunci: jagung, radiasi gamma, varietas ABSTRACTMutation is one of the ways to improve genetic variation in plant breeding so the target traits were more easily obtained. Grains of three varieties of maize (Bisma, Madura local, and Gumarang) were treated with gamma 60 cobalt irradiation doses (0, 100, 200, and 300 Gy) before sowing then planted in a split plot randomized block design with three replication, to be evaluated for their morphology and agronomic traits. The Main plot was cultivars and sub plot was gamma radiation rates. There was no interaction between gamma rates and cultivars of maize, but increasing of gamma rates caused decreasing of some traits. Some traits such as plant height and leaves number were decreased significantly when gamma rate increased 100 to 300 Gy as well yield components such as grain weight and grain number per ear. Gamma 200 caused produce more ears than other rates. Bisma exhibited greater performance than Madura and Gumarang both of morphology and agronomic traits.

Tanaman bayam merah memiliki kandungan gizi lebih yang baik dibandingkan dengan tanaman bayam hijau. Permintaan bayam merah di pasar perkotaan tergolong cukup tinggi. Produksi bayam merah secara indoor di perkotaan membutuhkan cahaya yang lebih dikarenakan intensitas cahaya yang kurang dalam bangunan perkotaan. Hal tersebut dapat diatasi dengan penambahan lampu LED karena memiliki spektrum cahaya yang sesuai dengan kebutuhan tanaman. Penelitian dilaksanakan untuk mengetahui daya lampu LED dan media tanam yang efektif untuk meningkatkan pertumbuhan dan hasil secara optimal tanaman bayam merah. Penelitian dilakukan bulan Oktober sampai Desember 2021 di Desa Bolorejo, Kauman, Kabupaten Tulungagung, Jawa Timur serta di Laboratorium Fakultas Pertanian UPN “Veteran” Jawa Timur. Penelitian menggunakan rancangan petak terbagi dua faktor, daya lampu LED dan media tanam dengan tiga kali ulangan. Hasil penelitian menunjukkan terdapat pengaruh nyata kombinasi perlakuan lampu led dengan media tanam hanya pada karakter berat basah dan kering, serta kadar klorofil bayam merah. Perlakuan daya lampu LED memiliki pengaruh nyata hanya pada tinggi tanaman dan jumlah daun. Tidak ada pengaruh nyata perlakuan media tanam pada semua karakter pengamatan. Lampu LED 6 watt dan media tanah kompos merupakan hasil terbaik pada berat basah dan kering bayam merah.

Mutation induction often used to increase genetic variability in plant breeding for further proceed. Thirty inbred lines of maize mutants (M1) of were evaluated in a randomized complete block design experiment with three replications for morphology and agronomy of genetic variability parameters. Data were collected on days to anthesis and silking, anthesis-silking interval (ASI), plant height, leaves number, days to maturity, ear number, grain yield, grains number, weight of 100-grain. Mean values were used to determine characters’ phenotypic and genotypic variances, phenotypic, genotypic and environmental coefficients of variation. Moderate heritability estimates were observed for most traits. Otherwise based on genotypic coefficient of variance, for most traits had low genetic variability but generally high genetic variability was observed for most traits based on standard deviation of genotypic variance. Grain yield as important trait had moderate genetic variability based on heritability estimates, high based on genotypic coefficient of variance and standard deviation of genotypic variance. Hence provides better opportunities for selecting plant material regarding these traits.

Chili (Capsicum sp.) is a vegetable commodity that is widely grown throughout the world after tomatoes are a member of the Solanaceae family, which have very many types, ranging from not spicy to very spicy. Chili originates from South America and Central America, Peru and Mexico and then brought by the Portuguese to Europe and Asia then spread throughout the world. Chili contains many compounds that are good for health, vitamin C, vitamin A, vitamin E, folic acid, flavonoid, phenol, capsaicin which can be used to treat malnutrition in society and non-infectious diseases such as heart disease, diabetes, cancer. The content of the nutrition depends on the genotype, environmental conditions, and the fruit ripening phase at harvest. In Indonesia, there are many local varieties or landraces of chili that have adapted well to the local environment. Local varieties are good genetic resources for developing new superior varieties of chili that have the quantity, quality, and resistance to environmental stress.
