Abstract

This study aims to compare the added value of green bean Luwak Coffee in the Kawa Gayo home industry in Central Aceh Regency with Luwak coffee powder ready for consumption. The research method used is a case study using the Hayami analysis method. The sample is determined purposively (purposive sampling), in which the researcher relies on his judgment when selecting members of the population to participate in the study. The data used in this study are primary data and secondary data. The results of this study indicate that the added value in the Kawa Gayo home industry for Luwak coffee powder is more significant than for Luwak coffee green beans with an added value of IDR 41,675. However this is not followed by the added value ratio of Luwak coffee powder variant which is smaller than the green bean luwak coffe on value added ratio of 30.96%. The business scale of the supporting costs that still exist using third parties in production is a factor that affects the added value of processing Luwak coffee grain into Luwak coffee powder in the Kawa Gayo home industry which has yet to be maximized. Home industry obtains higher profit on the Luwak coffee powder variant than the Luwak coffee green bean variant with a profit value of Rp. 37,595. However total of the profits in the home industry from the Luwak coffee green bean variant is higher than the Luwak coffee powder variant with Rp. 1,400,250 profit value. The demand for a variant greatly affects the total profit of Kawa Gayo home industry.

Abstract

Development and development of the quality of farming communities in carrying out farming is one aspect that supports the creation of increased agricultural production and productivity, so that profits can be increased. Agricultural development, especially horticultural crops that have been implemented, has made a positive contribution to economic development. The clearer and more obvious that the economic system is, the more it is influenced by the agricultural sector. This sector has an impact on the sustainability of the income of farmers in an area.Cultivation of vegetable crops in Indonesia is generally carried out with monoculture and polyculture cropping patterns. Monoculture is a cultivation system in an area of land planted with only one type of plant. Meanwhile, polyculture is a system of plant cultivation in the same area of land in one year planted with several types of plants, both planted at the same time or slightly different times. The development of pests and diseases tends to occur more easily in monoculture cropping patterns because food sources for pests and pathogens are always available. On the other hand, a polyculture cropping pattern followed by a crop rotation pattern can break the life cycle of pests and diseases.Crop rotation has many advantages. In some organic crop cultivation systems, crop rotation is highly recommended. Some of the advantages of crop rotation are that it can reduce the intensity of pest or disease attacks, increase soil fertility, and crop rotation is highly recommended. Some of the advantages of crop rotation are that it reduces the intensity of pest or disease attacks, increases soil fertility, and is able to form a stable micro-ecosystem. In addition, in the agribusiness world, several types of commodities, especially vegetables, are able to meet the desired market demand.

Abstract

Karo regency is center for carrot (Daucus carota L.) production in North Sumatra. It is estimated more than 1% of the rejected carrot yields are produced in each planting period. With the predicted harvest area, more than 1,000 tons of rejected carrots will be produced annually. This potential can be used as the material for the manufacture of liquid organic fertilizer (LOF). There are three research variables that were carried out, namely: 1) Independent variables consisting of fermentation periode consisting of 10 days, 20 days, 30 days and 40 days. 2) Fixed variable consisting of 4 kg of rejected carrots, 5 liters of water, 5 liters of old coconut water, 0.6 liters of brown sugar water, 0.05 kg of yeast, 0.5 liters of EM-4. 3) Bond variables consist of C-Organic content, Phosphorus content, Potassium content  and Nitrogen and pH content. The results showed that the peak of microorganism activity occurred on the 30th day. This treatment obtained the highest proportions of 0.07%, 0.14%, 0.87%  for Nitrogen, Phosphorus and Potassium levels respectively. The highest C-Organic content was obtained in the H-20 and H-30 treatments with a proportion of 1.55%. The acidity level was stable at a value range of 3.5 from the start to the end of the quenching process. LOF carrots produced are still not in accordance with established quality standards. The percentage value of macro elements, C-Organic and pH is still below the set quality standards.

Abstract

Research has been carried out using Mabar Compost and NPK Yara Mila 16:16;16 on lettuce (Lactuca Sativa L.). The aim of the study was to determine the effect of Mabar Compost Fertilizer, the effect of NPK Yara Mila 16:16:16, and the effect of the interaction between the two types of fertilizer on the growth and yield of lettuce plants. The study used a factorial randomized block design consisting of two factors. Factor I: Dosage of Mabar Compost with the symbol "K", namely K0: 0 Control (without treatment), K1: 350 grams/plot, K2: 550 grams/plot, and K3: 750 grams/plot. Factor II: Dosage of NPK fertilizer with the symbol "P", namely P0: 0 Control (without treatment), P1: 18 grams/plot, P2: 24 grams/plot, P3: 30 grams/plot. The results showed that Mabar Compost Fertilizer and NPK Fertilizer had no significant effect on the height and number of leaves of lettuce plants. Mabar Compost Fertilizer had a significant effect on the yield weight of fresh lettuce plants. The average yield weight of plants affected by compost was K0 (109.4 gr), not significantly different from K1 (120.2gr) but significantly different from K2 (125.4 gr) and K3 (165.2 gr). No interaction was found between the type of fertilizer and the dose of fertilizer on the research parameters.
