Abstract

Ultisol soils are agricultural lands in Indonesia, which are widely distributed, but have a problem, namely the element of N in the soil is relatively low, so it is necessary to do proper cultivation techniques, one of which is through the provision of balanced fertilizers, namely the application of organic fertilizers that aim to improve soil fertility and reduce soil fertility. use of NPK fertilizers. This study aims to determine the effect of giving various kinds of organic fertilizers, namely sometimes chicken and urea fertilizer on the chemical properties of Ultisol from Pangkatan. This research was carried out at the Agrotechnology Practice Field, Faculty of Science and Technology, Labuhanbatu Rantau Prapat University, with an altitude of 25 meters above sea level. The study began in February 2021 to June 2021. This study used a factorial Randomized Block Design (RAK) with 2 treatment factors. namely: Urea fertilizer factor with four levels and Chicken manure factor with three levels. Soil analysis parameters which include , pH H2O by electrometric method, determination of N-total soil by Kjehldal method, C-organic soil using Wakley and Black method. The results showed that the application of chicken manure was able to increase soil N-toatal in the Ultisol Rank soil, at a dose of U1K3 (Urea: 0.25g and Chicken Manure: 75g) while the interaction of urea and chicken manure application increased the N-total soil of Ultisol Rank with dose of U1K3 (Urea: 0.25g and Chicken Manure: 75g).

Abstract

This study entitled the provision of various organic materials on physical properties and ultisols in South Rantau District Labuhan Batu Regency was carried out in the experimental garden at the Labuhan Batu University, North Sumatra. This study aims to determine the best type of organic material to improve the physical properties of ultisol soil from the South Rantau land at the Labuhan Batu. This study used a non-factorial randomized block design (RBD) with a treatment factor of 8 types of organic matter and 3 replications so that there were 27 experimental units. L0 Treatment: Control, L1: Palm oil solid waste, L2: Sugar factory waste, L3: Fish waste, L4: animal feed waste, L5: Chicken manure, L6: Cow manure, L7: Leguminose compost, L8: Compost organic waste fertilizer Medan city with a dose of each organic material 150g / 10 kg TKO. After incubation, bulk density (g /cm3) was taken using the Ring Sample method, Total Pore Space (%) with soil particle density and permeability (cm/hour) using the De Bootd method. Research results fish waste has the highest significant effect in improving soil physical properties, such as reducing soil bulk density, namely 1.02 g / cm3, and increasing the total soil pore space by 61.63%. In contrast, the highest soil permeability is obtained in the treatment of animal feed waste, which is 59.51 cm/hour while the lowest was in the control treatment of 28.18 cm/hour. The application of fish waste had the highest significant effect in improving the physical properties of the soil, such as reducing the bulk density of the soil.

Abstract

Farmer’s Perceptions of the Use of People’s Business Credit (PBC) in Improving Coffee Farming Businesses in Sibolangit District, Deli Serdang Regency. This study aims to examine the level of farmer’s perceptions and examine the factors that influence farmer’s perceptions of the use of People’s Business Credit (PBC) in improving coffee farming. This research was conducted in Sibolangit District, Deli Serdang Regency, from April to June 2023. The data collection methods were interviews, questionnaires tested for validity and reliability, and recording, while the data analysis method used a Likert scale and multiple linear regression. The study results show that the level of farmer’s perception of using People’s Business Credit (PBC) in improving coffee farming is 82.42 percent. Partial further tests using tcount show that the factors of length of farming, income level, role of extension workers, social environment, and PBC socialization have quite a significant influence, with the tcount value being greater than the table.

Abstract

This study aims to analyze the attitude of smallholders towards the pruning process in oil palm plants in the Babalan Sub-district and to analyze the significance of the relationship between various factors and the attitude of farmers towards pruning in oil palm plants in the region. The research took place in Babalan Sub-district, Langkat Regency, from April to June 2022. The method used is descriptive with a quantitative approach. The total population of farmers involved in this study is 307 people who are working on oil palm plantations. They come from 2 villages, including South and North Securai Village. In South Securai, there are 5 farmer groups: Giat, Tani Jaya, Saolohan, Tani Jaya 1 and Tekun. In North Securai, there are 2 farmer groups: Bina Tani and Tuah Johor. This research instrument uses the Likert and Spearman Rank correlation scales for questionnaire data collection. The research found that 78.7% of smallholders had prejudices toward oil palm trimming. While the value of t-count > t-table as a result of the correlation of Spearman Rank states that between the age factor (t-count 2.159 > t-table 1.993), land area (t-count 3.078 > t-table 2.644) and the role of extension workers (t-count 5.626 > t-table 2.644) to the level of attitude of smallholders has a significant relationship. The implications of age, land area and the role of extension workers from the attitude of smallholders determine that oil palm pruning increases sustainable palm oil productivity.
