Potassium is a macro nutrient that can affect the quality and quantity of oil palm bunches as well as resistance to disease and drought stress. So far, testing the status of potassium nutrient uptake in people's plantations in Perlabian Village, Kampung Rakyat Labuhanbatu Selatan District has never been carried out. Fertilization and maintenance are carried out through knowledge from generation to generation, so it is important to have a study on the nutrient uptake status of potassium in oil palm leaves. This research was conducted using a free grid survey method at the semi-detailed survey level with a density of 100 meters. A total of 6 leaf samples were taken on the 17th leaf midrib and then rubbed with 70% alcohol and then put into the plastic sample for further testing in the laboratory of PT. Socfindo. The results showed that the potassium in leaf samples 1, 3 and 4 experienced deficiency and leaf samples 2, 5 and 6 were at the optimum. In oil palm plantations in smallholder plantations in Perlabian Village, Kampung Rakyat Subdistrict, it shows that the total K content of leaves is included in the optimum category.

Human development is one of the factors in increasing the implementation of national development. Human development that is implemented can be calculated with the human level, health and standard of living. Then the level of the human development index can also affect government spending in the education sector and the health sector. The use of the model in this article with the multiple linear regression program is used to process, classical assumptions of test data using SPSS 22. The results of the analysis show that farmer exchange rates can significantly affect the human development index in North Sumatra Province, government spending in the education sector has a significant effect on the human development index in North Sumatra Province and government spending on health sector spending has no significant effect on human development index in North Sumatra Province. This shows that government spending in the health sector has not been properly realized so that it is not strong enough to increase the human development index in North Sumatra Province. The results of research on government spending in the education sector have a dominant effect in increasing the human development index in North Sumatra province.

The neglect of returning organic matter to the soil and the intensive use of chemical fertilizers inpaddy fields have caused the physical, chemical, and biological quality of the soil to decline. Such soilconditions cause the population of soil biota that plays a role in nitrogen fixation and phosphatesolubility to decrease. This study aims to determine the relationship between total microbes andnutrient levels of N, P, K in rice plants in Ajamu Village, Panai Hulu District, Labuhan Batu Regency.This research was conducted from December 2021 to January 2022. Sampling was carried out bytaking leaves and rhizosphere soil of rice plants at 5 zigzag sampling points in a rice field area.Parameters observed in this study were nutrient levels of N, P, K and total microbes. The analysis wascarried out using correlation and regression methods.

This research was carried out in the agricultural field of the University of Harbor. The research began from March to June sky research (Cucumis Mello L) to determine the effect of giving fertilizers and goats and cultivating land on the growth and production of melon sky rocket varieties (Cucumis Mello L). This study used a Factorial Randomized Block Design (RCBD) with 2 factors examined and repeated 3 times. Goat MANURE (K) fertilizer dosing factor consists of 3 levels, namely: K0 = No treatment, K1 = 1 kg / Plot and K2 = 2 kg / Plot. The inhalation factor (G) consists of 3 levels, namely G0 = Tanpaper treatment, G1 = 1cc / L water / plot and G2 = 2cc / L water / plot. The administration of goat manure significantly affects the observation of plant height, number of branches, fruit weight, number of plots and the weight of plots. The application of ZPT has a significant effect on the observation of plant height and number of branches but has no significant effect on observing the weight of fruit per plots, the number of plots and the weight of per seed. The interaction between goat manure and ZPT did not significantly affect all observations. Keywords:Goat Manure, ZPT, Melond

Bitter melon is one of the types of potentially commercial vegetables if cultivated intensively on an agribusiness scale. In addition, bitter melon is a profitable agricultural commodity and trade material in local markets and supermarkets because it contains high nutrition that is complete and all parts of the medicinal plant bitter melon. Green giant is an organic fertilizer, in the form of pellets containing nutrients complete with high cation exchange capacity that will increase the availability of nutrients for plants, safe for the environment. Green Giant can improve physical, chemical and biological soil properties. Improving soil texture and structure is accompanied by neutralizing soil acidity, improving soil aeration and drainage, supporting the development of beneficial microorganisms in the soil and increasing the amount of nutrients that can be absorbed by plants. the application of leaf fertilizer which contains micro nutrients, the deficiencies can be overcome. The soil will avoid fatigue or damage by using leaf fertilizer.Key words : Green Giant, micro nutrients, fertilizer
