Publisher : Universitas Gorontalo

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.

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

Chili pepper (Capsicum frutescens L.) is a plant commonly cultivated in Indonesia. This research employed an empirical, quantitative experimental approach using a Randomized Block Design (RBD). The study included three treatment groups with varying concentrations of cigarette butt biopesticides: a control group, and treatment groups at 10 ml/L, 20 ml/L, and 30 ml/L. The results indicated that biopesticides derived from cigarette butt waste extracts significantly affected the control of whitefly pests on chili peppers. The ANOVA test yielded an F value of 150.044 with a significance level of 0.000, demonstrating a highly significant difference among the treatments. The control group exhibited the highest average mortality rate of 62.22% for pests, followed by the 10 ml/L treatment at 50.67%, the 20 ml/L treatment at 42.67%, and the 30 ml/L treatment, which was the least effective, with an average mortality rate of 32.00%. These findings suggest that higher concentrations of the extract are more effective in reducing the number of living pests, positioning this biopesticide as an environmentally friendly alternative for pest control.
