Abstract

Celery is a multipurpose plant with many health benefits that has not been widely developed, especially in Jambi. The problem is the lack of fertile land. This can be overcome by using planting media other than soil. The aim of this research is to obtain the best combination of planting media and drip irrigation water discharge for celery cultivation. This research was conducted in the Greenhouse of Penyengat Bawah Subdistrict in March-July 2023. The experimental design used a Completely Randomized Design (CRD) which was arranged in a factorial consisting of two factors. The first factor (planting media) consists of 5 levels which are a combination of a mixture of soil, areca nutshell biochar and swallow guano. The second factor is the water flow rate which consists of 3 levels, namely the flow rate of 2.8 ml/minute, 4.2 ml/minute, and 5.6 ml/minute with 2 repetitions. The parameters observed were analysis of the nutrient content of the planting medium, water content of the planting medium, plant height, number of leaves, and fresh weight of the plant. The results showed that the combination of planting media influenced all parameters. Providing water with different discharges affects the water content of the planting medium and the wet weight of celery plants but does not affect plant height, and number of leaves. The combination of soil planting media and areca nutshell biochar (1:2) with water supply of 5.6 ml/minute produces the best growth and results in the growth and production of celery plants (Apium graveolens L).

Abstract

ABSTRACT The conversion of land from forest land to plantation land causes the surface of the land to be exposed for quite a long time. This results in rapid decomposition of organic matter so that the organic matter content in the soil decreases rapidly. As a result, there was a decline in physical quality. The research was descriptive exploratory, with a field survey approach using a 1:10,000 scale work map and supported by soil analysis in the laboratory. Representative areas were selected using the Stratified Random Sampling method for three types of land use, namely rubber plantations, oil palm plantations and shrubs. Each soil sample was taken randomly 3 times on a slope of 3-8%. Sampling was carried out at depths of 0-30 cm and 31-60 cm. The parameters observed in this research were soil texture (pipette method), soil structure (field observations), soil organic matter content (Walkley & Black method), soil volume weight (gravimetric method), porosity (based on calculations), soil permeability (De Boodt method), and available soil water content (Plate Apparatus-Gravimetric method). The research results show that the conversion of secondary forest land to plantation land has an impact on reducing organic matter content, soil porosity, soil permeability, and available soil water content and increasing soil volume weight. It is necessary to conduct further studies on the impact of land conversion on the quality of soil chemical properties and find solutions so that the decline in soil quality that has occurred is slowed.   Keywords: conversion, degradation, forest, physical quality   ABSTRAK Alih fungsi lahan dari lahan hutan menjadi lahan perkebunan menyebabkan terbukanya permukaan lahan dalam waktu yang cukup lama.

Abstract

Tunas Makmur Farmers Group I of Ibru Village, Mestong District, Muaro Jambi Regency, Jambi Province has not yet made optimal use of a large amount of agricultural, plantation and industrial waste, due to farmers' lack of knowledge about biochar and its use to improve soil productivity. For this reason, the implementing team offers an easy, cheap and sustainable solution to manage and utilize abundant sources that can be used as a source of biochar. The objectives of implementing this community service activity can be achieved through: 1) counseling and training about the benefits of biochar to improve the physical and chemical properties of soil, 2) demonstration of making biochar from agricultural, plantation and industrial waste using drum pyrolysis, 3) assistance in calculating the dose given and application in the field through demonstrations on partner land on how to use biochars properly. Partners in this activity earn their main income from being food crop and plantation farmers. Agricultural, plantation and industrial waste is usually piled up on land and wasted because farmers do not yet have knowledge about the benefits of this waste. After conducting socialization and education through counseling and demonstrations about making biochar from agricultural and industrial waste, farmers have the motivation to use this waste as a source of soil carbon and as a soil conditioner.

Abstract

Peatlands naturally function as water storage, water supply, and water controller. However, if they are not managed properly, this can cause changes in the water system or hydrology, especially fluctuations in groundwater levels. The decline in groundwater levels in peatlands triggers oxidation and subsidence, especially during the dry season. One effort that can be made to control this decline is to carry out a water balance analysis, which will provide a spatial and temporal understanding of the water's condition. This research was carried out in the Mangsang area at HTI PT. Rimba Hutani Mas, Merang District, Bayung Lencir District, Musi Banyuasin Regency, South Sumatra. The research was carried out by the survey method using the Thornthwaite & Mather Water Balance method. The data used included dimensions of drainage channels, rainfall, temperature, ground water level, and canal water level. The calculated data consisted of average monthly rainfall, average monthly air temperature, potential evapotranspiration, accumulated potential water loss, available water capacity, monthly differences in soil moisture storage, actual evapotranspiration, deficit, surplus, and direct runoff. The research results show that in the Mangsang area of ​​PT. Rimba Hutani Mas, there was a water surplus in March, April, November, and December and a deficit in January, February, May, June, July, August, September, and October. Although the calculation results indicate that water-deficit months occur in January, February, May, June, July, August, September, and October, this research area has been anticipated to avoid groundwater level fluctuations through effective water management and the construction of canal blocks.

Abstract

Conversion of forests to oil palm and areca nut plantations contributes to the decline in groundwater levels, which ultimately causes drought. Differences in groundwater levels also affect the physical characteristics of peat, including its hydraulic conductivity. This study aims to analyze hydraulic conductivity values ​​at various depths of shallow (<40 cm) and deep (>40 cm) groundwater levels. This study was conducted for three months in the peatlands of Catur Rahayu Village, Dendang District, East Tanjung Jabung Regency, Jambi Province, covering the preparation to post-research stages. This study was conducted using a purposive sampling method, observations based on sample selection criteria including: (1) distance from the canal (50 m and 100 m), (2) variations in peat maturity levels (fibric, hemic, sapric), and (3) GWL depth (<40 cm vs. >40 cm). Hydraulic conductivity measurements were carried out three times per point to minimize errors, with instrument calibration before data collection. The results of the study showed that the hydraulic conductivity value at shallow groundwater levels ranged from 3.80 - 29.50 m / day, higher than the conductivity at deep groundwater levels which ranged from 3.38 - 4.14 m / day indicating the need for GWL regulation to mitigate peat drought. Based on the results of the study, other factors that influence hydraulic conductivity are peat characteristics, especially its maturity level. The more mature the peat, the smaller the pore size due to shrinkage of organic matter particles and decreased organic matter content; therefore, the hydraulic conductivity rate becomes slower. This study also revealed that the more mature the peat, the higher its volume weight, which has an impact on reducing hydraulic conductivity. This is due to the smaller size of organic matter particles, which reduces the pore space in the soil and increases its density. As a result, the movement of water in the soil becomes slower, which causes a decrease in the hydraulic conductivity value.
