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

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.
