Abstract

Banana plants are annual horticultural crops that have production capability without depending on the season and are widely cultivated in the tropic or subtropic areas. Tissue culture can produce good-quality banana seedlings in large quantities. To stimulate their metabolic systems, Banana plantlets from tissue culture require appropriate growing media and growth regulators such as auxin. The research aims to examine the effect of IAA auxin hormone concentration, the composition of sand: compost: husk charcoal and its interactions on the growth of raja bulu banana plantlets. The research was conducted in July - September 2019 at the Plant Physiology and Breeding Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang. The study used a complete randomized factorial design 4x2 with 5 replications. The first factor was IAA concentration (K) consists of 4 levels, K0: 0 ppm, K1: 30 ppm, K2: 60 ppm, and K3: 90 ppm. The second factor was the composition of growing media (M), M0: sand: compost: husk charcoal (1: 1: 1) and M1: sand: compost: husk charcoal (1: 1: 2). Data were analyzed by F test and proceeded by DMRT test at the level of 5%. The results showed that IAA significantly affected stem diameter, number of leaves, chlorophyll content and nitrate reductase activity of banana seedlings. The treatment of growing media significantly affected plant height and number of leaves. Concentration of 30 ppm IAA at all growing media increased significantly on stem diameter, number of leaves, chlorophyll content and nitrate reductase activity.

Abstract

Crossing is one of the breeding programs that can be done to get better plant varieties. Breeders select to determine the seeds that can be planted on subsequent planting. To increase the success of selection, segregation needs to be determined. The study's main focus was determining the frequency distribution and crop segregation. This research was conducted from November 2018 - January 2019 in Agroecotechnopark and Laboratory of Plant Physiology and Breeding, Diponegoro University, Semarang. This study used F2 seeds from crossing varieties of Fagiola x Aura Hijau. The experimental design was carried out using a single plant design. The results were analyzed using the distribution suitability test and chi-square test. Characters that have a normal distribution are plant height, number of leaves, length of pods, and sweetness. The character that is not normally distributed is pod weight. Two genes are dominant-recessive epistasis controlling pod weight.

Abstract

The fluctuating price of potatoes every year as well as the high costs of distribution, storage, and maintenance mean that farmers earn less profit than expected. The research aims to analyze supply chain management, marketing efficiency, and potato supply chain risks. The research was carried out in September 2023 in Pakis and Ngablak Districts, Magelang Regency. This research uses a survey method with a descriptive approach. Determining the institutional sample uses snowball sampling while the farmer sample uses Cluster Sampling or Multistage Random Sampling method. The pattern of flow of information, finances, and goods runs smoothly. In the calculation of the farmer's share of large-grade potato commodities obtained at the research location, channel I was 84.61%, channel II was 85.71% and channel III was 80.00%, including in the efficient category. The farmer's share grade value was obtained by channel I at 75.00%, channel II at 77.77%, including in the efficient category, channel III at 70%, including in the inefficient category. The small farmer's share grade value obtained by channel I was 71.42%, channel II was 75%, which was included in the efficient category and channel III was 66.66%, which was not included in the efficient category. There are 23 risk agents and 15 risk events in the potato supply chain in Ngablak and Pakis Districts, Magelang Regency. Phase 1 HoR analysis provides results based on the Pareto diagram that there are 3 priority risk agents, namely crop failure, potatoes damaged in transit, and natural factors or disasters.
