Abstract

A number of promising sweet potato clones from East Nusa Tenggara and a checked cultivar were evaluated in several locations for the following objectives:  1) to elucidate genotype by environment effect on growth and yield of the sweet potato clones, and 2) to determine growth and yield stability of the clones across diverse locations in East Nusa Tenggara province. The study was carried out in four locations and was laid out in a Randomized Block Design consisting of 10 sweet potato genotypes as treatments and two replicates. Obtained data were subjected to combined analysis of variance to determine GxE interaction, followed by stability analysis based on joint regression model of Eberhart and Russell. Research results revealed that genotypes, locations and genotype by location interaction posed significant effect on the observed variables. Most of the evaluated clones were unstable for vegetative growth characters but were stable for tuber yield and yield components. The local clone LB-01 produced the highest mean tuber yield over all locations, averaging at 4.15 kg.plant-1 (~ 46.11 t.ha-1).  Two local clones, i.e. ON-06 and LB-01, and the check cultivar Kidal were the most stable clones for tuber yield and yield components across diverse environments.     Keywords: growth, yield, stability, sweet potato, location

Abstract

Penelitian dilaksanakan pada bulan April sampai Juli 2021, di Kelurahan Baru, Kecamatan Reok, Kabupaten Manggarai, yang bertujuan untuk mengetahui pengaruh kombinasi pupuk biomassa kirinyu dan pupuk NPK Mutiara terhadap pertumbuhan dan produksi tanaman bawang merah (Allium ascalonicum L.). Penelitian didesain dengan Rancangan Acak Kelompok, dengan 9 perlakuan kombinasi, diulang dalam 3 blok, sehingga terdapat 27 satuan petak percobaan. Perlakuan yang diujicobakan berupa kombinasi dosis pupuk biomassa kirinyu dan dosis pupuk NPK Majemuk Mutiara. Variabel yang diamati adalah pertambahan tinggi tanaman, pertambahan jumlah daun, jumlah umbi per rumpun, bobot umbi bawang merah per rumpun dan per petak. Data pengamatan dianalisis dengan sidik ragam dan dilanjutkan dengan uji Duncan pada taraf 5 %. Hasil penelitian ini menunjukan bahwa: 1). Perlakuan kombinasi pupuk kompos biomasa kirinyu dan pupuk NPK Mutiara berpengaruh secara nyata pada variabel pertambahan tinggi tanaman dan pertambahan jumlah daun pada umur 20 - 35 HST, jumlah umbi, bobot kering umbi bawang merah per tanaman, dan bobot kering umbi per petak. 2). Perlakuan kombinasi pupuk kompos biomasa kirinyu dan NPK Mutiara pada perlakuan aplikasi pupuk biomasa kirinyu 20 ton/ha dan dosis NPK Mutiara 100 kg/ha (P5) meningkatkan pertumbuhan dan produksi bawang merah terbaik, dengan capaian bobot kering umbi bawang merah per petak sebesar 1,47 kg atau setara 14,7 ton/ha.

Abstract

This research was carried out in the Dry Land of the Faculty of Agriculture, University of Nusa Cendana with the aim to investigate the effect of the application of cow manure and SP-36 fertilizer on the yield of bitter melon. This study was laid out in a randomized block design (RBD) with 6 doses of cow manure and SP-36 fertilizer applications, namely: K0 = without cow manure and SP-36 fertilizer (control), K1 = 10 tons/ha cow manure and SP- 36 fertilizer 50 kg/ha, K2 = 10 tons/ha cow manure and SP-36 fertilizer 100 kg/ha, K3 = 10 tons/ha cow manure and SP-36 fertilizer 150 kg/ha, K4 = 20 tons/ha cow manure and SP-36 fertilizer 50 kg/ha, K5 = 20 tons/ha cow manure and SP-36 fertilizer 100 kg/ha, K6 = 20 tons/ha cow manure and SP-36 fertilizer 150 kg/ha. Each treatment was repeated 3 times in block. The parameters observed were: flowering age, harvesting age, number of fruit/plant, fruit length, fruit weight/plant and fruit weight/plot. The results showed that the application of cow manure and SP-36 fertilizer had a significant effect on all parameters observed. The best treatment in increasing the yield of bitter melon plants was the application of cow manure with dose of 20 tons/ha and SP-36 fertilizer 150 kg/ha. At this treatment, plant had faster flowering and harvesting ages, namely 30 HST and 50 HST, and produced the highest number of fruit/plants (6.8), the longest fruit size (29.90 cm), the heaviest fruit/plant weight (1220.67 gram) and the heaviest fruit/plot weight (18.31 kg).

Abstract

The Certificate of Good Manufacturing Practices (GMP) is a regulatory requirement in Indonesia to ensure the quality and safety of food and beverage products. However, many micro, small, and medium enterprises (MSMEs) in Kupang City have yet to obtain CPPOB certification, largely due to limited knowledge and skills in meeting the necessary requirements. This community service program aimed to assist an MSME in implementing CPPOB standards through a series of activities, including surveys, production process assessments, coordination with stakeholders, and mentoring to improve production systems. UMK Abon Yudhistira, located in Naikoten II, Kupang City, was selected as the model enterprise. The intervention focused on redesigning the production room layout to reduce the risk of cross-contamination arising from the movement of raw materials, finished products, personnel activities, and external factors. In addition, product packaging information was revised to enhance traceability in accordance with CPPOB guidelines. The program resulted in significant improvements in production practices, enabling UMK Abon Yudhistira to successfully obtain CPPOB certification from the Indonesian Food and Drug Authority. This initiative demonstrates that targeted technical assistance can effectively support MSMEs in achieving compliance with national food safety and quality standards.
