HUBUNGAN POPULASI CACING TANAH TERHADAP C-ORGANIK DAN N-TOTAL DI LAHAN BUDIDAYA HORTIKULTURA DAN MONOKLUTUR TANAMAN KOPI DI DESA NDUARIA KECAMATAN KELIMUTU

This study aims to determine the relationship between Earthworm Population and C-organic and N-total in Horticulture and Coffee Monoculture cultivation in Nduaria Village, Kelimutu District. This research was conducted using an exploratory method that is carried out by direct observation from the observation location. How to calculate earthworms using the hand sorting method. The method commonly used for the determination of C-organic is the Walkley and Black method, while the method used for the determination of N-total is the Kjehdahl method. This method is used because it is considered simple, fast, easy to do, and requires little equipment. The results of this study indicate that in horticultural land there is no earthworm population found at all depths. Earthworm populations were found at all depths in the coffee plantation monoculture, the highest population was at a depth of 0-10 cm as many as 41 m2, Biomass was 9 g, and Biomass vs Population 0.21 m2. In horticultural fields, the highest c-organic and n-total is at a depth of 0-10 cm, the c-organic value is 3.03% (high criteria) and n-total is 0.47% (medium criteria). The close relationship between the earthworm population, biomass, and biomass versus population was positively correlated with c-organic and n-total in horticultural land and coffee monoculture.

RESPON PERTUMBUHAN TANAMAN KANGKUNG (Ipomoea aquatica) TERHADAP PEMBERIAN BIOAKTIVATOR

The purpose of this research was to examine the response of water spinach plants to the application of bioactive fermented liquid organic fertilizer on plant growth. This research used a method consisting of two treatments and one combination, namely a combination of watering and spraying treatments, as well as watering, spraying, and control. This experimen was conducted in the outdoor laboratory of SMKN 63 Jakarta, on land Kale plants. From this research, it was found that the combination of watering and spraying treatments was significantly higher and gave the best results compared to the watering, spraying, and control treatments. Based on the results of the study, it is known that there are differences in harvest age between the treatments of Watering, Spraying, Watering & Spraying and Control. The fastest harvesting age in the treatment of Watering & Spraying. Bioactive has a positive effect on vegetative growth and has a biopesticide effect. This is presumably because Bioactive is made from organic material/agricultural waste by aerobic and anaerobic fermentation methods so that from the fermentation it produces amino acids and alcohol which have an effect against plant vegetative growth and pests that often appear on crystal guava and breadfruit plants. During and after the experiment, no signs of pests or diseases were seen on the plants.

Analisis Pendapatan Usahatani Kakao Di Kabupaten Ende (Kajian pada Desa Kedebodu dan Rewarangga)

One of the leading plantation commodities in Indonesia is cocoa (Theobroma Cacao). Through the Decree of the Minister of Agriculture and Plantation (Kepmentan) No.46 / Kpts / PD.300 / 2015 Ende Regency, East Nusa Tenggara [NTT] was determined as a mainstay cocoa plantation area, but in fact, the production was not optimal. Based on these considerations, this study aims to determine the level of cocoa farming income and the factors that influence farmers' income and analyze the feasibility and usefulness of a cocoa farming fund. The method used in this research is the descriptive method. The research location was determined by purposive sampling, based on the consideration that the area is a cocoa-producing region in Ende Regency. Sampling is the Ende Selatan District of Kedebodu and Rewarangga Villages. The population is all cocoa farmers, with a sample of 20 respondents. Data were collected by interview, questionnaire, observation, and documentation techniques. The feasibility analysis is done by the B / C ratio analysis. In addition to the analysis also conducted an analysis of income and receipts with the formula TC and TR. The results showed a B / C ratio of 5.24% which meant that the cocoa business was profitable and feasible to be developed. Total income from cocoa and non-cocoa is Rp 315,732,000. and from cocoa alone. Rp 91,532,000, - and total revenue of Rp. 73,897,000, and non-cocoa Rp. 29,933,000. While the total cost of cocoa is IDR 17,635,000 and non-cocoa IDR 194,267,000. Factors influencing the cocoa business in Ende District include level of education, gender participation, labor age, age of old cocoa plants, and not yet applying profitable technology. It is advisable for farmers to intensify cocoa farming by implementing P3S, and post-harvest processing, forming young people groups and building networks of cooperation with all stakeholders.
