Abstract

Kolaka is known as "Kolaka Cocoa City". Cocoa is the main commodity of Kolaka Regency. Kolaka is one of the cities in Southeast Sulawesi. Southeast Sulawesi is one of the provisions in Sulawesi which is the center of cocoa production after South Sulawesi with total area of 260,458 ha and with production 142,156 tons (Ditjenbun, 2012). Cocoa production centers in southeast sulawesi are located in Latambaga and Samaturu Sub-districts. Partners in the IbM program are cocoa farmers of Induha Urban Village, Latambaga Sub-district and cocoa farmer in Samaturu Sub-district. Various cooperation programs have been conducted to improve the quality of cocoa commodities in Kolaka District. In its development, classical problems remain faced by partner farmers both in terms of production and business management. In terms of production, pre-harvest problems faced by farmers are cocoa pests and diseases, which cause the farmers’ dependence on pesticides and chemical fungicides as well as the age of plants, therefore, it is important to reduce the use of pesticides and chemical fungicides because in the long term it can have adverse impact on environmental sustainability and health. The problem of post-harvest for partner farmers is a low quality of cocoa production. Most cocoa farmers process cocoa fruits to be dried beans in a rough way so that ± 90% of the cocoa beans produced by farmers have a low quality with the main characteristic is not fermented. The problem faced by farmers  in the marketing chain is the oligopsoni market structure, where farmers are at the lowest position so that farmers do not have bargaining position. The objectives of IbM program were to 1) Reduce farmers’ dependence on pesticides and chemical fungicides with the utilization of environmentally friendly pesticides 2) Design the fermentor to improve the quality of cocoa beans 3) Enhance the bargaining position of farmers through the active role of Farmer group (Gapoktan)  in the marketing chain of cocoa

Abstract

Seed viability is one of the most important physiological quality benchmarks of seeds. The use of appropriate germination media can affect the results of seed viability testing. This study aims to determine the optimal germination media in tobacco seed viability testing. This research was conducted at the Seed Laboratory of the Indonesian Sweetener and Fiber Crops Research Institute, Malang in January - March 2019. The research method used a two-factorial randomized block design (RAK). The first factor is tobacco seed varieties consisting of Kasturi in 2007, Bojonegoro in 2012 and Kemloko in 2014. The second factor is the seed germination media consisting of straw paper, cotton, towel tissue, paperboard and newspaper. The results showed that the Kemloko variety of tobacco seeds germinated in the towel tissue had the best seed vigor and viability percentage. Seed germination media with paperboard, towel tissue and straw paper can be used to test the viability of tobacco seeds because they have a percentage of simultaneous growth, percentage of the growth speed, percentage of germination, percentage of the growth potential maximum and normal seedling dry weight which are equally well

Abstract

Excellent seedling selection and NPK fertilization can accelerate seedling, stem, leaf, and fruit growth. This study aimed to determine the effect of the number of seedlings and NPK-Phonska fertilizer on the growth and yield of lowland rice based on the leaf-color chart approach. This study was conducted from December 2021 to April 2022 in Puuroda Village, Baula, Kolaka. This study applied a randomized block experimental design with two-factor treatments, namely the number of seedlings and NPK-Phonska fertilizer dose. For the number of seedlings factor, there were one seedling per clump (B1), two seedlings per clump (B2), and three seedlings per clump (B3). The NPK-Phonska fertilizer factor contained two treatments, namely, without fertilizer treatment (M0) and fertilizer treatment based on the average dose of leaf-color chart (M1). The results of this study showed that two and three seedlings per clump had higher growth and yield of lowland rice, based on the plant height, maximum number of tillers, number of productive tillers, panicle length, dry grain yield (kg/plot), grain yield (ton/ha). The NPK fertilizer affects the growth and yield of lowland rice based on the leaf-color chart.

Abstract

Cabbage is a popular horticultural commodity in the community with great potential development in highlands and lowlands. Nutrient fulfillment is a factor that supports optimal cabbage growth and production. This study aimed to determine the effect of different bat guano fertilizer doses on the growth and production of cabbage in lowlands. The cabbage type used was a suitable variety at lowlands called Grand 22. This study was performed in the experimental land of the Faculty of Agriculture, UNCP at 2 masl on September – December, 2021, through a randomized group design with six treatments and four replications. The treatments included: P0 = Control (without bat guano treatment), P1 = 30 g of bat guano per crop, P2 = 60 g of bat guano per crop, P3 = 90 g of bat guano per crop, P4 = 120 g of bat guano per crop, and P5 = 150 g of bat guano per crop. The results indicate that bat guano significantly affects all observed parameters. The 150 g of bat guano per crop provides the best effect on the cabbage height (27.75 cm), leaf width (27 cm), crop-forming age (36.5 days), and crop weight (1106.5 g).

Abstract

Cayenne pepper is one of the horticultural commodities with high economic value in Indonesia. In addition, this plant also never runs out of enthusiast because almost everyone needs it. Therefore, the fulfillment of this demand must be supported by the availability of sufficient cayenne pepper in Indonesia. This research aims to obtain better diversity in the results of double cross and three way cross than their parents, to obtain characters with good genetic parameters in predicting the results of double cross and three way cross crosses, and to obtain hybrid combinations of cayenne pepper resulting from double cross and three way cross which has purple fruit properties. The results of the evaluation of crosses showed that all cross-evaluation characters had a high heritability predictive value and were followed by high genetic diversity in the characters of plant height, dichotomous height, plant habitus, flowering age, harvesting age, fruit weight, fruit length, fruit diameter, fruit stalks length, and yield.

Abstract

The utilization of phenotype technology in breeding is directed to see and select plants based on the appearance of the targeted phenotype. One is modern technology based on geographic information systems and remote sensing. The unmanned aerial drone (UAV) uses computing and machine learning in image processing and information extraction. This research focuses on developing tolerance screening of several varieties to drought based on the drone-vegetation index. This study used nine rice varieties in the rice fields of Kab. Bone-SulSel in the dry season. This research aims to identify the best selection character as a measure of tolerance of rice varieties to drought based on image and morphophysiology, which will be used to develop image-based phenotype-based selection methods. This research was conducted with Randomized Block Design (RAK) consisting of 3 replications. The morpho-physiological parameters of several rice varieties showed a significant effect, including the Inpago 15 variety, which gave the best results on NDVI characters and was followed by other characters. The vegetation index, or the greenness of the vegetation value obtained from digital signal processing of several channels of satellite sensor data, can provide information that a plant has good vegetation. The varieties that gave the best treatment were the Inpago 15 and Jeliteng varieties. The results of the correlation analysis showed that the parameter with a significant positive correlation with productivity was the weight parameter of 1000 grain (r=0.35).

Abstract

This study aimed to identify the effectiveness of seedling trays in screening rice for salinity tolerance. The study was conducted at the greenhouse, Faculty of Agriculture, Hasanuddin University, from August 2022 to October 2022. The genotypes used consisted of 4 dihaploid lines (F37, F42, F46, and F47), which were tolerant to salinities in nutrient culture screening. The Duncan Multiple Range Test (DMRT) with STAR 2.0.1 software and regression analysis with Microsoft Excel were used to analyze the interaction between genotype and environment. The results showed that the characters of shoot length (SL) and shoot fresh weight (SFW) were significantly influenced by all sources of diversity. In addition, the F37 and F42 genotype had a stable tolerance to saliency stress. The SFW character of F42 was more affected by SL than SL in the screening with soil media in trays. Based on the two evaluation characters (SL and SFW), fixed crown height is recommended as a selection criterion with SFW for the screening of saline-tolerant rice.
