Abstract

The household is the smallest unit in society, so it can be said that household income means community income. This study aims to determine the determination of the variable income, economic activity, and household members, as well as differences in the location of residence to the consumption of oil palm farmers in Labuhanbatu Regency. The method used to analyze data with multiple linear regression models, by certifying in the Least Square Dummy Variable (LSDV) method. The estimation results found that all independent variables were positive and significantly influenced the amount of food consumption, on the contrary were negative and significant towards non-food consumption expenditure. The estimation results also found that the amount of consumption of various types of foodstuffs in urban communities was smaller than the food consumption of inland communities amounting to Rp.1,248,000. However, greater than the consumption of food for coastal communities is Rp. 1,323,800. While the amount of consumption expenditure for various types of non-food for urban communities is greater than non-food consumption for inland communities Rp.2,782,000. And also greater than non-food consumption of coastal communities, namely Rp. 3776 000. Variation in the ability of independent variables in explaining food consumption by 92.5 percent, and expenditure for non-food consumption by 87.4 percent. The model specification is very good with the model being free from violations of the classical assumptions of multicollinearity and heterokedastisitas.

Abstract

Human development is one of the factors in increasing the implementation of national development. Human development that is carried out can be calculated with the level of human health and standard of living. Then the level of the human development index can also affect the value of increasing per capita income and economic growth. The use of the model in this article was processed with the multiple linear regression program and classical assumptions test data using SPSS 22.The results of the analysis produce farmer value added (X1) which can significantly affect the human development index (Y) in North Sumatra Province, government spending in the education sector (X2) can significantly affect the Human Development Index (Y) in North Sumatra Province and government spending on health sector expenditures (X3) has no significant effect on the Human Development Index (Y) in North Sumatra Province. It shows that government spending in the health sector (X3) 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 the research on government spending in the education sector (X1) have a dominant effect in increasing the human development index in the province of North Sumatera.

Abstract

Pakcoy (Brassica rapa L.) is a type of mustard that is quite economical. Currently, the pakcoy plant is used by the community in various dishes. This plant is quite easy to cultivate and only requires a short time of about 3-4 weeks. The aim is to obtain data on the growth response and production of pakcoy plants to the application of liquid organic fertilizer banana peels. Liquid fertilizer is a fertilizer whose basic ingredients are animals and plants that have been undergoes fermentation and the product form is in the form of liquid, one of which is banana peel waste which is used for the manufacture of liquid fertilizer because it contains micro elements N, P and K. Because many people process processed production from bananas which always produce banana peel waste in processing the waste is only disposed of and left to pile up by the community, if not handled quickly it will produce an unpleasant odor so that it will pollute the environment, one alternative is the service team invites socialization and training to the community by processing the banana peel waste into liquid organic fertilizer with the fermentation process tation, so that people can use liquid organic fertilizers instead of using chemical fertilizers that are more expensive for all plantation crops.

Abstract

Peatlands are formed from piles of trapped plant residues, obstructing their decomposition process. The organic matter decomposition process certainly involves soil microbes. This study aims to determine the biological characteristics of peat soil after incubation with vermicompost. This research was conducted at Kampung Perlabian Village, Kampung Rakyat Sub-district, South Labuhanbatu Regency, North Sumatra. Soil biological analysis was conducted in the soil biology laboratory, Faculty of Agriculture, University of North Sumatra. This study used a non-factorial Randomized Block Design (RAK) with three treatments: P0 (control), P1 (1 kg peat soil + 500-gram vermicompost), and P2 (1 kg peat soil + 1 kg vermicompost). The results showed that adding vermicompost fertilizer to peat soil with treatment two could increase the total bacteria by 6.17 x 106 cfu/ml and the total fungus by 8.8 x 105cfu/ml, and CO2 respiration by 4.125 (mg CO/day). As a result, the soil's microorganism's activity is a process in which microorganisms live and do activities in a soil mass.
