Abstract

The development and utilization of peat soil as a plant growing medium cannot be separated from limiting factors, one of which is the chemical properties of peat, namely low pH, very high cation exchange capacity (CEC) with very low base saturation (KB), and low macro and micro nutrients, resulting in low soil fertility and inhibited nutrients for plants. The provision of ameliorant in the form of sea mud is one alternative to improve the chemical properties of peat. The use of sea mud as a soil conditioner can improve the chemical properties of peat considering its high base content such as Calcium (Ca), Magnesium (Mg), Sodium (Na) and Potassium (K) cations. The high base content in sea mud can improve nutrient availability, low pH availability, can increase base saturation and reduce the high cation exchange capacity in peat soil. Improvement of peat soil characteristics with the addition of sea mud ameliorant can affect peat soil fertility. The purpose of this study was to study and analyze the role of sea mud in improving the chemical properties of peat. This study uses descriptive analysis by testing laboratory data of liquid sea mud. The parameters used in this study are soil pH, base saturation, cation exchange capacity, Sodium, Calcium, Potassium and Magnesium. The provision of sea mud on peat soil is given at a level of 5% and 7.5% on 10 kg of peat soil. The use of sea mud at a level of 7.5% gives better results in terms of decreasing the value of cation exchange capacity, increasing pH, increasing base saturation, increasing sodium, potassium, calcium and magnesium elements. Initial analysis of initial soil pH ranges from 3.37, KB 7.74% and CEC 119.66 cmol (+) kg-1, Sodium content 0.6 cmol (+) kg-1, calcium 5.37 cmol (+) kg-1, potassium 0.37 cmol (+) kg-1, and Magnesium 2.87 cmol (+) kg-1. But after the treatment of 7.5% sea mud there was an increase in pH to 3.54, KB 17.49% and CEC 112.29 cmol (+) kg-1, Magnesium 10.72 cmol (+) kg-1, Calcium 7.20 cmol (+) kg-1, and Sodium 0.66 cmol (+) kg1. The results of the study showed that the provision of sea mud on peat soil can improve the chemical properties of peat, especially the provision of sea mud at a level of 7.5%. This proves that the use of sea mud has great potential in improving the limiting factors found in peat soil.

Abstract

The objective of the study is to test the chemical content of alluvial soil with the application of manure. Alluvial soil has poor physical and chemical soil properties, including low pH, nutrients, C-organic soil cation exchange capacity and a low C/N ratio. Therefore, it requires action to improve the planting by adding manure ameliorant. This research was carried out from February 5th, 2023, to April 5th, 2023 in Sambas Regency, Sambas District. This research uses a descriptive analysis model by comparing laboratory analyses using samples before and after the incubation process for 30 days. The treatments referred to in this research are: chicken manure, cow manure and goat manure. The dose of alluvial soil and manure used is 1:1. The parameters used in the research include soil pH, soil CEC, organic carbon (C), C/N ratio, elements nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results of the research showed that there were changes in the chemical properties of the soil after being treated using chicken manure, cow manure and goat manure when compared to the untreated soil. The use of chicken manure on alluvial soil has a more beneficial effect on changes in soil pH values, soil CEC, C-organics, C/N ratio, N, P, K, Ca, and Mg elements when compared with the use of cow manure.

Abstract

Pepper (Piper ningrum L.) is a strategic spice crop in global trade. Two types of pepper are commonly traded in both domestic and international markets: white pepper and black pepper. Sambas Regency is one of the pepper centers in West Kalimantan Province. Sumber Harapan Village is one of the pepper-producing villages in Sambas Regency. Some residents of Sumber Harapan Village have pepper, but the pepper production is not as abundant as in other areas. The pepper produced by the Sumber Harapan Village community is divided into two types: black pepper and white pepper. This study used a quantitative research method, using a total sampling method with 16 respondents. This study aimed to compare the production levels of black pepper and white pepper in Sumber Harapan Village. The results of this study indicate that the ratio of black pepper to white pepper production in Sumber Harapan Village in 2023 was 1:9, meaning that for every 1 kg of black pepper, there are approximately 9 kg of white pepper. The ratio of black pepper to white pepper production in Sumber Harapan Village in 2024 was 1:7, meaning that if a farmer produces 1 kg of black pepper, they will also produce 7 kg of white pepper. Keywords: Black Pepper and White Pepper, Comparison, Production Level.
