Abstract

White oyster mushroom is one type of mushroom that is popular in Indonesia. This study aims to determine the rate of change in water content and weight loss of white oyster mushrooms during storage. This study used a Completely Randomized Factorial Design with two treatments with 3 replications. The first treatment (A) was the difference in storage temperature (10, 20 and 30oC) and the second factor (B) was the difference in CO2 gas concentration (control, 20, 30 and 40%). Parameters observed were water content and weight loss. The results showed that the water content before storage was 90.47%, after storage at a temperature of 10oC for 10 days increased in the range 92.71% - 93.81%. The temperature 20oC for 8 days increased in the range 93.54% - 94.02%, while at 30oC for 3 days it increased 94.36%. White oyster mushroom weight before storage ranged from 100.00 g - 110.00 g after storage at 10oC for 10 days weight loss in the range of 2.04% - 2.1%. Storage temperature of 20oC for 8 days decreased in the range of 2.37% - 2.90%, while at 30oC for 3 days it experienced 4.01%. The Q10 value of the highest water content change was obtained at the addition of 30% CO2 with a value of 3.00. The Q10 value of the highest weight loss change was obtained at the addition of 0% CO2 with a value of 1.18.

Abstract

Anthocyanin is a type of pigment in black rice that is classified as a flavonoid compound and has antioxidant property. This study focused on testing anthocyanin content on four local varieties of black rice in Indonesia, namely Toraja (South Sulawesi), Cempo Ireng (Yogyakarta), Wojalaka (East Nusa Tenggara), and Manggarai (East Nusa Tenggara). Analysis of total anthocyanin content was carried out based on the absorbance value of rice flour extract at a wavelength of 535 nm with a spectrophotometer. This study used a randomized block design with varieties as groups and each was carried out in 20 repetitions. The total anthocyanin content was analysed using a UV-Vis spectrophotometer with an absorbance length of 550 nm and 700 nm. The results showed that there were significant differences in the total anthocyanin content of the four varieties of black rice. Sequentially the anthocyanin levels of black rice varieties from highest to lowest were Manggarai with an average anthocyanin content of 1508.89 ppm, Cempo Ireng with an average anthocyanin content of 734.86 ppm, Wojalaka with an average anthocyanin content of 435.38 ppm, and Toraja with an average anthocyanin level of 117.2 ppm.

Abstract

Plants that are symbiotic with microbes will produce phytohormones optimally, increasing plant tolerance to abiotic and biotic stress, including plant pathogens, so it is necessary to investigate the rhizosphere mushroom of onion plants in Enrekang regency and test the production of phytohormones (IAA and GA3) to determine its potential as a biostimulant in Shallot. This study used soil samples of shallot rhizosphere soil collected at the shallot farming center in Enrekang regency, as well as hormone isolation and testing at Hasanuddin University's laboratory of plant diseases. The results obtained are 20 isolates with IAA hormone production ranging from 0.125-3,609 mg / L, with isolate 3 and 7 having the highest IAA production, while GA3 hormone production ranges from 0.991-3,440 mg/L, GA3 production is released in isolates 8, 17, and 19. This demonstrates the high potential of rhizosphere mushrooms as biostimulants.

Abstract

Porang (Amorphophalus Muelleri) is a tuber plant from Araceae family that is easily live in various types and soil condition. In the food industry porang flour is used as a thickening agent, emulsion stabilizer and gel former, while in the pharmaceutical industry it is used as a coating material. This was do the increased in demand for exports of porang tubers in the form of flour and chips. The increasing demand for porang, so that porang cultivation has economic value. The selection of the appropriate fertilizer is one of the efforts to increase porang productivity. Therfore, the aim of this research was to obtain the scintific data about interaction of organic waste market fertilizerand growmore fertilizer toward of vegetative growth of porang plant. This research used RAL Factorial have 2 factor with 3 treatments level each others were the first factor is doses of organic waste market fertilizer (0g/polybag, 200 g/polybag and 400 g/polybag) and the second factor is doses of growmore fertilizer (0 g/l, 1 g/l and 2 g/l). The parameters in this research were plant height, petiole diameter, number of petioles and number of lateral roots of porang plant. The result on this research showed that interaction of organic waste market fertilizer and growmore fertilizer was signicantly affected of plant height, petiole diameter and number of lateral roots, but did not significantly affected of number of porang petioles. The best treatment obtained from interaction of organic waste market fertilizer at dosage 400g/polybag and growmore fertilizer at a dosage 1g/l.

Abstract

Cultivation of lemons needs to be increased due to the increasing demand for lemons. This requires a large amount of seedling. One alternative material for cuttings for lemongrass nurseries with lots of supplies is leaf cuttings. The aims of this study were to determine the effect of onion extract concentration on the growth of leaf cuttings and to determine the best concentration of shallot extract on the growth of leaf cuttings. The experimental research was in the form of extract treatment, which consisted of 5 levels, namely control (without immersion), immersion in water, 10% onion extract, 20% onion extract and 30% shallot extract. Leaf cuttings were soaked in onion extract at various concentrations for 2 hours. The observed variables included the percentage of living cuttings, the percentage of roots formed, the number of roots, the length of the roots, the percentage of damaged leaves, the percentage of shoots formed and the length of shoots. All treatments showed 100% survival rate and root formation percentage. Treatment of 20% onion extract can increase the number of roots, root length, percentage of shoots formed and shoot length from lemon lime leaf cuttings at 60 days after observation. The results of this study provide information that cuttings from leaves can be used as an alternative in the vegetative propagation of lemon and onion extracts as an alternative to growth regulators.

Abstract

The relationship between farmers and other agribusiness institutions is a form of performance of agribusiness institutions in achieving the desired goals. Although not all of these relationships are good, the connectedness of farmers with other institutions is tied to the relationship of mutual need. This then raises the question, whether sustainability is based on satisfaction or is it just a mere economic motive. Based on this background, the objectives of this study are: 1) identifying agribusiness institutions connected to farmers in Talungeng Village, Barebbo District, Bone Regency, 2) analyzing the performance of agribusiness institutions in Talungeng Village, Barebbo District, Bone Regency, 3) analyzing farmer satisfaction with the performance of agribusiness institutions in Talungeng Village, Barebbo District, Bone Regency. The research will be conducted in Talungeng Village, Barebbo District, Bone Regency, considering that the area is an area that has good agricultural potential. In addition, the area is a Self-Sufficiency village where community access to facilities is sufficient, especially agribusiness institutions. The research will be carried out for 6 (six) months. Data that has been taken in the field will be analyzed using descriptive analysis, Importance Performance Analysis, and Consumer Satisfaction Index. The results showed that in running a farming business, farmers are in contact with several agribusiness institutions including farmer groups and farmer shops, mobile mills, collectors and agricultural extension workers. In general, the performance of agribusiness institutions is relatively good and meets the expectations of farmers. Farmers' satisfaction with the performance of agribusiness institutions is relatively good

Abstract

The research was conducted at KP2 of the Institut Pertanian Stiper located in Maguwoharjo Village, Depok District, Sleman Regency, DIY. With an elevation of 118 mpl. The research was conducted from August 4, 2022, to November 1, 2022. The research was carried out using a factorial design that was arranged in a completely randomized design (CRD) and consisted of two factors. The first factor was the planting medium, which consisted of 4 levels: M0, regosol soil (control); M1, soil + cow manure (2:1); M2, soil + rice husk (2:1); and M3, soil + cow manure + rice husk (1:1:1). The second factor is the origin of the cutting material, which consists of 3 levels, namely the top of the segment (B1), the middle stem of the segment (B2), and the rootstock of the segment (B3), and each is 15 cm long. So that 4 x 3 = 12 combinations are obtained. Each treatment was repeated five times, resulting in the acquisition of 60 units. Experiment The research data were analyzed by analysis of variance (Anova) at the 5% level. If there is a significant effect, a DMRT follow-up test is carried out at the 5% level. The planting medium and cutting material interacted with plant height, number of shoots, number of leaves, fresh weight of roots, and dry weight of plants. Meanwhile, for fresh weight of plants, dry weight of roots, and leaf width, there was no interaction between the planting medium and the cutting material.
