Abstract

Empowerment activities to improve the ability of coffee farmers in Kerinci Regency are very important to be implemented. The purposes of this study are to describe the empowerment activities undertaken by coffee perfume agroindustry practitioners towards coffee farmers in Kerinci Regency and to explain the empowerment potentials of coffee farmers performed by coffee perfume agroindustry practitioners in Kerinci Regency. This research was designed qualitatively with descriptive methods. Data was collected using a focus group discussion (FGD) method with the informants selected in this study as many as 16 coffee farmers and Kerinci Coffee Perfume entrepreneurs themselves. Data analysis was performed using the Miles and Huberman method. The results showed that the empowerment activities carried out by coffee perfume agroindustry practitioners for coffee farmers in Kerinci Regency were still not available, because kerinci coffee perfume agroindustry practitioners only provided training to coffee farmers working in coffee farms owned by the agroindustry entrepreneurs. Meanwhile, the potential for empowerment of coffee farmers by coffee perfume agro-industry prractitioners in Kerinci Regency is very high, because the characteristics of coffee farmers that have a sense to develop and easily receive information to improve their abilities and skills in producing high quality coffee beans. Based on this, henceforth, this research can be directed at the strategy of empowering coffee farmers in Kerinci Regency by kerinci coffee perfume agro-industry practitioners and the impact of empowerment that has been done.

Abstract

This study was conducted to assess the biocontrol efficacy of arbuscular mycorrhizae fungi (AM Fungi) against stem rot disease caused by Sclerotium rolfsii Sacc. in peanut. The AM Fungi can be associated with almost all types of plants. The purpose of this study was to obtain isolates of arbuscular mycorrhiza fungi (AMF) as a potential biofungisida against Sclerotium rolfsii and can characterize the mechanism of the FMA in controlling S.rolfsii (salicylic acid) on peanut plants. The AM Fungi inoculant (40 spores g-1 in concentration) was introduced to peanut seedling (25 g plant-1 ) at planting time where as Sclerotium rolfsii inoculated 30 days after planting time. The experiment was arranged in the completely randomized design (CRD), which is 7 treatment sand repeated 10 times in the greenhouse experiment. The data were analyzed using analysis of variance (ANOVA) using STAT program 8 and the Tukey test at 5% significance level. The AM Fungi treatments showed significantly redused the percentage of disease severity in infected peanut plants around 34.28% - 57.15% and longer incubation period, respectively. They increased root colonization (20,00 - 46.67%) with a middle to high category. The AM Fungi C isolate (isolated from Solok county), and the A isolate (isolated from Payakumbuh city) were the best as a biocontrol against S rolfsii (57.15%), followed by isolate D (isolated from Padang Pariaman county) 54,30 %. They also increased Salicylic acid content 1,4 times (70.72 ppm) compared to control (49,59 ppm). It can be concluded that the application of AM Fungi as a biocontrol agent played an important role in plant resistance and exhibit greater potential to protect peanut plants against S. rolfsii.

Abstract

This study aims to estimate genetic parameters including genetic diversity coefficient, phenotypic diversity coefficient, heritability value, and the correlation between the character of plants from eight soybean varieties. The research was conducted from August to December 2017, in the Wasafi Village of Prafi District, Manokwari Regency. The study was designed using Randomized Block Design (RBD) with 8 treatments of soybean varieties. Each treatment was repeated 4 times, to obtain 32 experimental units. The data obtained were analyzed using ANOVA and if it had a significant effect, it was further tested using the Duncan Multiple Range Test (DMRT) at the 95% level, through the Costat program. The results of ANOVA analysis were used to obtain Variable Partition values, Genetic Diversity Coefficient (GDC), Phenotype Diversity Coefficient (PDC), and Heritability. Correlations between characters were also analyzed using the Costat program. Estimation results of genetic parameters indicate that the characters selected for selection criteria are based on the value of GDC, PDC, and high heritability are number of branches, number of fertile books, number of filled pods, and number of total pods. The characters that show a positive correlation with the character of the results are plant height, number of trifoliate leaves, harvest age, number of filled pods, number of empty pods, total pods, and number of seeds per plant, while characters that show a negative correlation to a seed weight character are flowering age.

Abstract

The limiting factor affecting the production of sorghum in Indonesia is the rapid decline of sorghum seed vigor and viability. One way of restoring vigor and viability is hydration-dehydration. This study aimed to know that invigoration with the hydration-dehydration method can improve the quality of physiological sorghum seed and to determine the most appropriate conditions to use. This experiment used a completely randomized design (CRD) with 3 treatments and 4 replicates and was conducted at the Laboratory of Seed Science and Technology, Andalas University from January until March 2019. The treatment in these trials are: A = not hydrated-dehydrated seeds (control), B = Hydration for 1 hour and dehydration for 6 hours at the temperature 400C, C = high-quality seeds. The data were analyzed using the F test at the 5% significance level. Significant differences were further analyzed using an Honestly Significant Difference (HSD) test also at the 5% level. The results showed that hydration-dehydration can increase the vigor and viability of sorghum seeds from 56% to 70,5% and 55% to 75%.

Abstract

Okra is a functional vegetable with good nutritional content and medicinal benefits. The red okra cultivar has a lot of fruit in a single plant but have a short harvest period, thus the weight and size of the fruit are small. One of the techniques in the improvement of okra cultivar is performed by hybridization with the introduced okra varieties that have a longer harvest period. The objective of the research is to evaluate the crosses between red okra with the introduced okra varieties and to obtain plants from the crosses that have a longer fruit harvest period character. The research was conducted at the Research Station of the Faculty of Agriculture, Andalas University from Mei to October 2019. The materials used are the local red okra genotype, Ve-022, and B-291 introduced varieties as well as two of the crosses population of SOMB291 and SOMVe022. The whole plant is a red okra cultivar and the crosses are planted in a plot with a spacing of 40 x 50 cm. The performance of the crosses was analyzed using descriptive statistics. Results showed that the plant obtained with a longer harvest period of 8 days after anthesis as much as 19 and 12%, respectively in the population of SOMB291 and SOMVe022. The increase in crop life in plants from the somb291 and somve022 populations resulted in a plant that has a greater length, diameter, and weight than the red okra population. The increase in the harvest period results in a greater length, diameter, and weight of fruit.

Abstract

Potatoes have the potential to be developed as a source of carbohydrates in supporting food diversification programs. Reduced potatoes production has resulted from a decrease in the land area for potato cultivation. The effort that can be made to increase land productivity is through multiple cropping systems such as intercropping, intermittent intercropping, streak planting, annual intercropping, and agroforestry. It is necessary to use idle land under plantation stands that have not been optimized, in increasing productivity and efficiency of agricultural production systems. This study aims to get the varieties that have the best growth and yields planted under immature coffee stands. This research applies a Single Factorial Experiment in Completely Random Design, where the factor is four levels of potato varieties, Granola (V1), Bliss (V2), Kentang Merah (V3) and Batang Hitam (V4). Observations made include plant height, number of leaves, leaf length, leaf width, tuber length, tuber diameter, weight per tuber, number of tubers/plat, and total tuber by grade tubers (Small, Medium, Large, Very large). Based on the analysis variance of each observation variable shows, there is an effect of the variable observation except the width of the leaves. Granola provides the best response to the growth and yield of potato plants

Abstract

This study aims to describe the marketing channel of garlic from Nagari SalayoTanang Bukik Sileh and to analyze the efficiency of the marketing channel. The study used a survey method, and data were gathered from 30 farmers who chose randomly from 103 farmers and intermediary traders. The research finds that there are four types of marketing channels of garlic in the area. The market channels are as follows: 1) Farmers → Breeders → Farmers, 2) Farmers →wholesalers→Retailers→ Consumers, 3) Farmers → Retailers (in the form of dried onions) → Consumers, 4) Farmers → Retailers → Consumers. Moreover, there is no proportional shared profit among the four marketing channels. Farmers received lower earnings than their proportionate profits, but on the other hand, the benefits received by breeders, wholesalers, and retailers were higher than their proportional profits, so that the marketing channels were inefficient.
