Abstract

Dark Septate Endophyte (DSE) is a fungus in symbiosis with the host plant and is characterized by the presence of dark pigment, insulated hyphae, and microscleretia. The effect of DSE fungi on the host plant is specific according to the fungal strain, host plant species, and environmental conditions. DSE fungi can colonize host plant roots intra and extracellularly as well as ectendomycorrhiza. In DSE colonization, sometimes it fails to form a dense mantle and hartig net, but instead, it forms melanin microscleretia. The symbiosis between DSE fungi and suitable host plants can increase plant growth, uptake of N and P elements, resistance to drought, extreme temperatures, and protect plants from plant-disturbing organisms. The increase in the uptake of N and P elements was caused by the ability of DSE fungi to produce proteolytic enzymes and phosphatases that can mineralize organic N and P so that they become available to plants. Increased resistance to drought and extreme temperatures is thought to be due to melanin hyphae which can help absorb water from the soil and produce antioxidants and protection against free radicals. In addition, some strains of DSE fungi also produce chlorine to protect plants from plant-disturbing organisms.

Abstract

This study aimed to 1) evaluate the implementation of activities for the Acceleration of Food Consumption Diversification (P2KP) in Makassar City, 2). to analyzing the correlation between P2KP activities and the Expected Food Pattern (EFP) score in Makassar City, 3) analyzing/identifying changes in the quality of food consumption after participating in P2KP activities. The population in this study was the Women Farmers Group (WFG) beneficiaries of P2KP activities as many as 8 KWT in 8 sub-districts. Each sub-district has one WFG consisting of 30 households, so that the total population is 240 household. The sample was determined by Simple Random Sampling, namely 20% of the population, so there were 48 household. The results showed that the P2KP program in Makassar City with the success rate of program implementation included in the high category, namely 79.4%. There is a very significant relationship between P2KP activities and the Expected Food Pattern (EFP) score. There was a change in the quality of food consumption as reflected in the change in the Expected Food Pattern (EFP) score before and after P2KP activities. The higher the EFP score, the more diverse the food consumption.

Abstract

Chili is one of the commodities with a high enough economic value that needs the community and is one of the export commodities. The use of silver, black mulch (SBM) is one of the production inputs essential in increasing production. This study aims to determine the production of chili plants by applying SBM and without the application of SBM (according to farmers' habits). The research was conducted from October 2017 to January 2018 in Banggae, East Banggae District, Majene Regency. The experiment was conducted using hybrid varieties, namely Lingga, Green Temper, and Purple Temper varieties, while the non-hybrid varieties used were Pilar, Arimbi, and Darmais. The experiment consisted of three replications using a randomized block design (RBD). Observation parameters included fruit per tree, chili fruit weight, fruit length, fruit diameter, and fruit stalk length. The results showed the best application of SBM compared to not applying SBM on the parameters of fruit number, fruit weight, production, and chili fruit characteristics (fruit length, fruit diameter, and chili stalk length). Most chilies were found in the Temper Purple hybrid chili, which reached 50.45 pieces. The highest fruit weight of chili was found in the non-hybrid chili of the Darmais variety, which was 21.05 g per fruit.

Abstract

The increasing population and the demand for soybean consumption in Indonesia are not comparable to soybean production, which is still low. Land conversion and changes in climate patterns that cause drought stress are also triggers for low production. Drought stress can be anticipated by using drought stress-tolerant cultivars at various growth phases. This study aimed to determine the effect of drought stress on yields and yield components of several soybean cultivars. In addition, to determine the soybean cultivars that are most resistant to drought stress. This study was arranged experimentally using a factorial (3x2) split-plot design. The main plot, namely drought stress, consisted of three levels: watering once a day, once every three days, and watering once every six days. The sub-plots were soybean cultivars with three replications consisting of 2 levels, namely Wilis and Anjasmoro cultivars. The selection of these 2 cultivars was made on purpose because farmers had easy access to seeds. Determination of drought stress-resistant cultivars using the stress tolerance index (ITC). Drought stress caused almost all yield and yield component variables to decrease, such as the number of pods, the number of seeds per pod, and the total weight of seeds. Based on the stress tolerance index (ITC), it is known that the Wilis cultivar is more tolerant to drought stress than the Anjasmoro cultivar.

Abstract

Gorontalo's paddy fields had decreased from 833 Ha in 2019 to 916 Ha in 2010. The decreased means there has been a reduction in the rice field area of around 83 Ha for nine years. Land conversion is one of the factors that farmers in Gorontalo City cannot avoid. The household food security of lowland rice farmers in Gorontalo City based on the food security score is in a food-insecure condition, 60.43%. This study aims to analyze the factors that influence the dynamics of staple food adequacy at the household level of lowland rice farmers in Gorontalo City. The research was carried out in the Gorontalo City area in July-September 2020. Primary data were sourced from lowland rice farmers in Gorontalo City, while secondary data was obtained from BPS, Food Service, and sub-district offices. The sampling technique was a simple random method with a total of 66 rice farmers. Data analysis to measure the model of factors that influence the dynamics of food sufficiency at the household level of rice farmers in Gorontalo City uses a linear probability model. The results showed that the factors influencing the dynamics of staple food adequacy at the household level of lowland rice farmers in Gorontalo City are rice production, rice consumption, farmers' exchange rate (NTP), land area, and total household income. Meanwhile, education, age, and several dependents did not significantly affect the adequacy of basic food in Gorontalo City.

Abstract

Garlic is one of the agricultural commodities needed by people in Indonesia. The productivity of local garlic produced is still low due to the limited availability of seed tubers and the non-uniform quality of tubers. Production and quality of garlic seed bulbs can be increased through the shelf life of bulbs at low temperatures by tissue culture techniques. This study aimed to determine the effect of the shelf life of tubers at low temperatures and the composition of growth regulators on garlic shoot induction. The design used was a randomized block design for two treatment factors and 15 replications. The first factor was the shelf life of tubers at low temperatures, which consisted of 4 treatments, namely 0, 10, 20, and 30 days. The second factor is the composition of growth regulators consisting of: 2.0 ppm Kinetin + 0.4 ppm 2.4-D; 2.0 ppm NAA + 2.0 ppm BAP; 0.5 ppm NAA + 2.0 ppm 2ip; and 0.2 ppm NAA + 2.25 ppm BAP. The results obtained from this study were that the shelf life of 0 days with the composition of ZPT 2 ppm NAA + 2 ppm BAP, and shelf life of 10 days 0.5 ppm NAA + 2.25 ppm BAP affected shoot emergence time, the number of explants sprouted, and percentage of explants sprouted.

Abstract

Salted egg is an egg preservation product that aims to improve the taste, aroma, appearance of the yolk, and color through salt diffusion into the egg. This study aims to compare various types of eggs on the physical and organoleptic qualities of salted eggs. This study used a completely randomized design (CRD) consisting of 4 treatments, namely duck eggs (P0), broiler eggs (P1), free-range chicken eggs (P2), and duck eggs (P3). Parameters measured in this study were egg yolk and white pH, egg weight loss, and organoleptic quality. The results showed that using various types of eggs had a significant effect (p<0.05) on egg yolk pH, weight loss, yolk color, egg yolk texture, saltiness, saltiness level, and acceptance of salted eggs. However, it had no significant effect (p>0.05) on egg white pH, egg white color, salted egg aroma, white egg texture, and salted egg taste. Goat eggs are the best type in optimal pH and are the most preferred by consumers organoleptically.
