Abstract

Availability of pepper seeds continuously, good quality, and free from stem rot disease is still limited at the farmer level. This study aims to determine the composition of the planting medium and the best concentration of organic fertilizers in spurring pepper seeds' growth. The study was compiled using a two-factor factorial design based on a randomized block design. The first factor is the media's composition for planting sand, compost, and soil in 5 levels, namely 1:0:1, 1:1:0, 1:1:1, 1:2:1, and 2:1:1. The second factor is applying liquid organic fertilizer (POC), made from forage. It consists of three levels of concentration, namely POC 10 ml, 20 ml, and without POC (control). Fifteen treatment combinations were repeated three times. The results showed that the combination of POC and the composition of the planting medium could stimulate pepper seedlings' growth. POC 20 ml/liter and the composition of the media of sand + compost + soil 1:1:0 and 1:1:1 resulted in the best shoot lengths, namely 13.91 cm and 13.23 cm, respectively. The planting medium of sand + compost + soil with a composition of 1:1:1 was able to spur the emergence time of pepper cuttings faster, namely 19.13 days after planting, and the number of leaves was higher, namely 5.40.

Abstract

The cocoa bean fermentation process is carried out to improve the quality of cocoa beans as industrial raw materials such as the formation of aroma, color, and flavor can increase the selling value. This study aims to examine the quality of the results of the addition of mixed culture and single culture Lactobacillus plantarum and determine the best quality of fermented cocoa beans with the addition of mixed culture and single culture Lactobacillus plantarum. The cocoa beans used for fermentation were RCC clones from Nglanggeran, Gunung Kidul. This study used a randomized block design (RAK) with different concentrations of yeast and bacteria, namely: single culture 5%, 10%, 15%, and mixed culture 5%, 10%, and 15% with a long fermentation time of 6 days. Cocoa beans without yeast and bacteria inoculum were used as controls. The single culture and the mixed culture used influenced the different results. The best treatment using a single culture was a single culture of 10%, while the treatment with the addition of mixed cultures was a mixed culture of 10%. The results of the research analysis of some of the best parameters are as follows: 37.85oC temperature measurement; pH 5.37; yield 31,369; seeds 100 grams 76.25; water content 7.848%; lactic acid 0.1125%; acetic acid 0.281%; reducing sugar 5.1065; total fat 50.70%; and cut test organoleptic test the preferred treatment by the panelists was Mixed Culture 5%.

Abstract

The waste generated by the nickel mining business has the potential to reduce soil fertility, causing plants not to grow normally and produce optimally. In fact, due to the high Ni content in the soil, it will be absorbed by the plants so that it cannot be used as food. The study aimed to determine the growth and absorption of nickel in mustard greens by applying compost and liquid fertilizer to nickel-polluted soil. The study used a randomized block design (RAK) with liquid fertilizer (PC) and compost application. The treatment consisted of (1) control (no PC + no compost); (2) Without PC+ compost 15 tonnes/ha; (3) Without PC + compost 20 tonnes/ha; (4) Without PC+25 tons/ ha; (5) PC 10 ml/liter + No compost; (6) PC 10 ml/liter + compost 15 tons/ha; (7) PC 10 ml/liter + compost 20 tons/ha; (8) PC 10 ml/liter + compost 25 tons/ha, which was repeated 3 times and consisted of 3 plants in each treatment. Data were analyzed using ANOVA and further testing with BNJ Test 0.05. The results showed that mustard plants on nickel-contaminated soil could grow normally and without poisoning symptoms. The application of 4 liters/ha of liquid fertilizer and 25 tons/ha of compost produced a higher number of leaves and fresh weight of mustard plants and were significantly different from other treatments. Mustard plants can absorb and accumulate nickel in the roots and leaves in the range of 425-455 mg/kg plant dry weight. Using green mustard plants in remediating land contaminated with heavy metals, especially nickel, can be an alternative by adding compost and liquid fertilizer to increase the biomass of mustard plants. However, it still has to be appropriately monitored, and the plants produced are not recommended for consumption.

Abstract

The availability of quality seeds affects the quality and production of soybeans produced. Seed quality often deteriorates due to prolonged storage, thus requiring in-vigoration treatment. The study aimed to determine the effect of organic matriconditioning media and inorganic matriconditioning media on improving the viability and vigor of soybean seeds. The research took place from September to December 2023. The research was organized using a completely randomized design with 5 treatments, consisting of 3 (three) matriconditioning media made from organic materials: husk charcoal, sawdust, and rice straw, and 2 (two) matriconditioning media made from inorganic materials: brick powder and fine sand. The results showed that the organic-based matriconditioning media group had a significant and better effect than the inorganic-based matriconditioning media on germination, germination speed, and germination uniformity, sprout dry weight, sprout length, number of leaves, and plant height of soybean. The treatment of organic matriconditioning media in the form of husk charcoal and sawdust has a better effect than other treatments.
