Abstract

Aluminum stress is a limiting factor for crop production on acid dry land with a low pH. The objectives of this study were to evaluate aluminum-tolerant upland rice varieties in acid dry land. The study was carried out using a completely randomized block design (RCBD) consisting of 8 varieties, namely IR64, Inpago 7, Dodokan, Dod-Pup1, Situ Bagendit, Situ Bg-Pup1, Batur, Batur-Pup1, and 4 strains, namely 19 (PB5)-2, 20 (PB8)-1, 21 (PB15)-1, and 22 (PB16)-1. The results showed that the Situ Bagendit variety with the Pup-1 locus gave the highest yield per plot compared to other varieties and lines, namely 287.5 g. These results also correlate with the ability of the variety to withstand aluminum stress, with a tolerance value of 3.00 (rather tolerant).

Abstract

To obtain quality cocoa seedlings, maintenance efforts are required during the nursery stage, including meeting the nutritional needs of the planting medium which can be in the form of organic fertilizer from goat manure and husk charcoal. In addition, efforts to improve growing media in nurseries can be used with biological fertilizers, including plant growth promoting rhizobacteria (PGPR). Goat manure for plant nutrients, as well as a source of nutrients for PGPR. The research objective was to determine the effect of media composition and PGPR on the growth of cocoa seedlings. Research with the experimental method of factorial design consisting of two factors was arranged using a completely randomized design. The first factor was soil planting medium: goat manure: husk charcoal (v/v) consisting of 3 levels: M0 = 1:0:0 (control), M1 = 1:1:0 and M2 = 1:1:1. Factor II, namely the dose of PGPR consists of 3 levels: K1 = 10 ml/seedling, K2 = 20 ml/seedling, and K3 = 30 ml/seedling. With three repetitions. Observational data were analyzed with variance at the 5% level. To find out the differences between treatments, the Duncan's Multiple Range Test was continued at 5% level. The results showed that there was no significant interaction between media composition and PGPR dosage on the growth of cocoa seedlings. The composition of the soil medium : goat manure : husk charcoal 1:0:0 and 1:1:0 gave good growth of cocoa seedlings. PGPR doses provide the same growth of cocoa seedlings.

Abstract

Abstract - The use of several varieties of green beans supported by NPK fertilizer and relatively easy cultivation techniques means this plant has good prospects as a business opportunity in the agribusiness sector because demand is quite large yearly. This research aimed to evaluate the appropriate dose of NPK fertilizer for the growth of several Mung Bean varieties. This research used a Randomized Block Design to treat several green bean varieties, Vima 1, Vima 2 and Vima 3. At the same time, the NPK fertilizer doses were P0 (without fertilizer), P1 (100 kg/ha), P2 (150 kg/ha) and P3 (200 kg /Ha). The research showed that fertilizer application only affected plant height, number of pods per plant and seed production per ha. At the same time, several varieties affected plant height and seed production per ha. The interaction of fertilizer application and several varieties significantly affects seed production per ha. Based on research results, applying fertilizer at a dose of 200 kg/ha gave the highest results in the growth and production of green beans. Based on the results of this research, it is also known that using several green bean varieties shows that the V-3 variety provides the best results in growth, and the V-2 variety provides the best results in production.

Abstract

Abstract--Ultisol soil has low organic matter content, high levels of leaching and evaporation, high Al saturation, and low nutrient availability. To overcome several ultisol soil problems, it is necessary to apply vermicompost fertilizer. Vermicompost is compost from soil used to raise worms, which affects soil structure and contains N, P, K, CA, Mg, S, and Fe. The research aimed to determine the characteristics of ultisol soil after applying vermicompost fertilizer and the growth of cocoa seedlings. Implementation of Research at the Pijoan Experimental Garden, Batanghari Regency. The experiment used a Completely Randomized Design (CRD). Observation data were analyzed using analysis of variance and the Duncan New Multiple Range Test (DNMRT) at the 5% level. The treatment tried was vermisol fertilizer with four dose levels, K0: 100% ultisol soil, K1: 85% ultisol soil + 15% vermisol fertilizer, K2: 75% ultisol soil + 25% vermisol fertilizer, K3: 65% ultisol soil + 35 % vermicompost per polybag. Providing vermicompost fertilizer with K2 and K3 treatment can increase N-total, P-Bray 1, and C-organic soil, increasing the pH of ultisol soil. Fertilizing vermicompost on ultisol soil had a significant effect on shoot dry weight and cocoa plant quality index. However, it had no significant effect on plant height, stem diameter and root dry weight.

Abstract

Abstract - During the main harvest, salak becomes very cheap, so it doesn't have a good impact on farmers. To overcome this, farmers must process the fruit into products such as dodol, sweets, chips, sweets, and extracts. This processing produces seeds that have not been utilized. This research aims to process salak seeds into coffee and analyze their contents, potentially food and health products such as antioxidants, caffeine, and proximate analysis. This research is a descriptive study that examines the making of coffee salak seeds and their contents. Making and taking samples was done at the Salak Abian Farmers Group, Sibetan Village, Karangasem. Sample preparation was carried out at the Denpasar Health Polytechnic Health Analysis Section. The sample analysis testing process was carried out at the Laboratory Services Unit, Faculty of Agricultural Technology, Udayana University. The data was analyzed descriptively by presenting tables and narratives of the results obtained regarding product potential. The technological development of salak coffee as a local food product is the processing of the seeds into powder, which is roasted to become coffee. The method of making it is straightforward, almost the same as processing coffee. The content of antioxidant chemicals, caffeine, and proximate analysis can potentially become a local food product typical of Karangase that is globally competitive. This is supported by the antioxidant capacity content of 436.91 mg/L and IC50% 9.37 mg/mL, low caffeine 0.207%, low fat 2.95%, and carbohydrates 80.98%. It is also supported by 6.24% water, 3.49% ash, and 6.34% protein.
