Abstract

This study aims to analyze the effect of using Pelangi NPK fertilizer and implementing the Let's Advance People's Businesses (MAKMUR) Program on the production and welfare of oil palm farmers in Semaja Village, Sei Menggaris Subdistrict, Nunukan Regency. The research method used a quantitative approach with an analysis of income, profits, and the feasibility of farming through the R/C Ratio and Break Even Point (BEP) indicators. The results of the study show that the use of Pelangi NPK fertilizer and assistance from the MAKMUR Program can increase the productivity of fresh fruit bunches (FFB) by 15-20% compared to traditional fertilization patterns. This increase in productivity had a direct impact on increasing farmers' income and welfare

Abstract

One way to manage dry land in providing water for plants is fertilization. Fertilization or the application of organic materials directly to the soil can improve the physical, chemical and biological properties of the soil. Fertilizer and water can work together to increase the growth of avocado plants, fertilizer can help store water in the soil and improve soil quality. This study aims to obtain the optimal integrated fertilizer dose and sufficient watering intervals for the growth of pre-generative avocados (Persea americana). The expected outputs are journals and sub-books. The study used a randomized block design (RAK). Fertilization treatment (P) consists of nine treatments, namely: 1) 2 kg chicken manure fertilizer + 2 gr NPK + watered once when planting 2) 2 kg chicken manure fertilizer + 2 gr NPK + watered once in 3 days, 3) 2 kg chicken manure fertilizer + 2 gr NPK + watered once in 5 days, 4) 2 kg chicken manure fertilizer + 3 gr NPK + watered once in 3 days, 5). 2 kg of chicken manure + 3 g of NPK + watered once every 5 days, 6) 2.5 kg of chicken manure + 2.5 g of NPK + watered once every 3 days, 7) 2.5 kg of chicken manure + 2.5 g of NPK + watered once every 5 days, 8) 3 kg of chicken manure + 2 g of NPK + watered once every 3 days, 9) 3 kg of chicken manure + 2 g of NPK + watered once every 5 days. This RAK was repeated 4 (four) times, resulting in a total of 36 experimental plants. The experimental design used was a randomized block design (RAK) with a single factor of fertilization. The research parameters were plant height, number of tertiary branches, total N, and soil invertase activity
