Abstract

Intensive land use in the long term can cause land degradation, affecting soil fertility, especially on Vertic Endoaquepts in Pati that have been managed as rainfed rice fields. The characteristics of rainfed rice fields are low nutrient availability and rice yields. This study aimed to determine the effect of tillage depth management and soil ameliorants on nutrient availability, plant uptake, and rice yield in rainfed rice fields. The field experiment that was conducted at farmer’s field used a split-plot design. The main plot was the treatment of tillage depth treatments (OT), with depths of 10 cm (T1) and 20 cm (T2). The subplots were ameliorant treatments (A), consisting of A1 = sugarcane leaf compost, A2 = rice straw compost, A3 = chicken manure, and A4 = cow manure, with each dose of 5 t ha-1. The Inpari 32 rice variety was grown for 95 days. Available N, P and K of the soil were measured at 0, 62, and 94 days after transplanting (DAT). Plant N, P, and K contents, plant height, number of tillers, and rice yield were measured at 62 DAT. The results showed that the interaction of soil depth and ameliorant significantly affected soil available P and K but had no significant effect on soil available N. Ameliorant treatment of cow manure significantly increased rice yield.

Abstract

Ultisols have considerable potential in developing agricultural cultivation, but in their management, they face several obstacles, including physical properties that do not adequately support plant growth. The low content of soil organic matter causes poor soil physical properties. Low organic matter content leads to low soil aggregate stability, obstructing pore distribution and infiltration so the soil can easily become compacted. This study aimed to observe the changes in some physical properties of the soil due to the application of cow manure and Gliricidia sepium pruning compost and its effect on the yield of soybean plants. This study used a randomized block design with five treatments, namely, K0 (without cow manure-Gliricidia compost), K1 (5 t ha-1cow manure-Gliricidia compost), K2 (10 t ha-1cow manure-Gliricidia compost), K3 (15 t ha-1cow manure-Gliricidia compost), and K4 (20 t ha-1cow manure-Gliricidia compost). The results showed that the 15 t ha-1 cow manure-Gliricidia compost was the best dose in improving the total pore space and penetration resistance of the soil studied. The application of 15 t ha-1cow manure-Gliricidia compost significantly increased soybean yield, reaching 2.97 t ha-1.

Abstract

The Digital Elevation Number (DEM) is the main tool for quantitative geomorphological tests. Furthermore, Shuttle Radar Topography Mission (SRTM) images with a resolution of 30 m have been widely used as a source of DEM data in geomorphological studies, while DEMNAS (National DEM) images with 8 m are rarely used. Both images can identify typical volcanic morphology based on a visual comparison of hillshade with certain variations in slope. The objective of this study was to determine the feasibility of DEM for tectonic activity assessment based on morphotectonic indices. In this study, geomorphological comparisons were carried out on twelve watersheds in the Seulawah Agam Volcano (SAV). The data extraction of DEM resulted in the total area and perimeter, namely 486.8 km2 and 455 km (SRTM), as well as 482.8 km2 and 460.3 km (DEMNAS). The total segments up to the 4th order and the resulting lengths were 290 and 512.8 km for SRTM, while DEMNAS were 527 and 711.7 km. The morphotectonic variables used included drainage density, bifurcation, circularity, and valley floor ratio, as well as basin shape index. The results of these parameter calculations using mean values of SRTM imagery showed very coarse textures, deformed, more elongated, moderate tectonic, and low uplift. On the other hand, those of DEMNAS imagery showed coarse textures, not-deformed, more elongated, low tectonic, and low uplift of the basin’s characteristics.

Abstract

The soil in the upstream Bengawan Solo watershed is at high risk of degradation related to a high erosion rate. Finding the proper crop type with land suitability is critical to protect against further soil degradation. This study aimed to determine the land suitability of white turmeric (Curcuma zedoaria) and the limiting factors in the upstream Bengawan Solo watershed community forest. This research was descriptive-explorative based on a survey of four land map units (LMUs) of Sumberejo village (LMU1, LMU2, LMU3, and LMU4), Batuwarno, Wonogiri. The number of sample points at each LMU depended on the total area of the LMU and was repeated four times. LMU results from overlay soil type maps, administrative maps, rainfall maps, and slope maps. Land suitability assessment was analyzed using the matching method. The land suitability classes of the upstream Bengawan Solo for white turmeric were S3 eh, and N eh. The limiting factors on land suitability for white turmeric are erosion hazards and slopes. The efforts to improve the limiting factor can be made by contour cultivation and repairing the terrace.

Abstract

This paper aims to characterize and test the stability of sulfuric natural water (SNW) from Sebau East Lombok as a sulfidation agent for several dissolved metals (Mn, Cu, Pb and Fe). The parameters used for SNW characterization are temperature, pH, DO, BOD, COD, TSS, and TDS. The sample was divided into two categories, namely the sample with preservation treatment and the sample without preservation, to study the stability of SNW. The SNW stability was determined by observing the SNW parameters in both samples at a storage time of 5, 10, 15 and 20 days and reacting them with dissolved metals. The SNW with preservation had reduced sulphide levels from day 1 to day 20, ranging from 59.24 mg/L to 17.70 mg/L, whereas the sample without preservation had decreased sulphide concentration from 52.46 mg/L to 9.56 mg/L. Furthermore, the SNW with preservation has a relatively superior metal reduction ratio than the sample without preservation. The maximum value of the deposition ratio for Mn metal was obtained on the fifth day with 57.60%, 83.45% for Cu, and 91.87% for Pb. This trend is not applicable for Fe, whereas the highest reduction (87.23%) was obtained on the the15th day's storage.

Abstract

Reclamation (revegetation) activities must be carried out upon the completion of mining. Limestone dust can affect the physical, chemical, and biological properties of soil. To increase the growth rate of non-wood product species such as coffee, biological fertilizers of mycorrhiza are introduced to the reclamation site. The goal of this study is to examine the effects of limestone dust covering former mines and different doses of mycorrhizal biological fertilizers on the growth of coffee seedlings. The research was conducted using the Randomized Complete Block Design method. Research areas were divided into groups/blocks consisting of soil without limestone dust, dust-covered 0-2.5 cm, and dust-covered 0-5 cm. The groups were treated with the addition of 10 g, 15 g and 20 g mycorrhizal biological fertilizers with five replications each. NPK inorganic fertilizer was given every one month to all treatments. The parameters observed from the growth of coffee seedlings were plant height, Stem diameter, and number of leaves. Based on the results, limestone dust influenced soil conditions such as silt, clay, pH, organic C, bulk density, and C/N ratio. In addition, limestone dust affected the plant height and number of leaves of coffee seedlings compared to those grown in an area without dust. Differences in the amount of mycorrhizal biologic fertilizers were significant (p<0.05) and tended to increase for the parameters of height and diameter of coffee seedlings. However, the difference in the dose of mycorrhizal biological fertilizers has been shown to significantly (p<0.05) decrease the number of leaves.

Abstract

Rivers on Java Island are one of the water supply sources to meet the surrounding population's water needs. However, only large, high-priority rivers underwent a comprehensive water quality assessment. Rivers that aren't a priority are rarely examined, such as sub-watersheds in Kuntulan, Rejoso. Upper Serayu, Gajahwong, and Glondong. The surrounding community utilizes these five watersheds for irrigation, industry, and domestic. Hence, analyzing the water quality index in the five watersheds during the dry season is necessary. The method used in this research is a comparison of the water quality results between the standards of the Indonesian government and WHO, as well as a comparison of the Water Quality Index (WQI) and Pollution Index (PIj). The method often used in Indonesia is PIj, while WQI is more global and hardly used. The difference in the two ways is expected to provide variations in the water quality index. The water quality parameters were pH, TDS, TSS, COD, PO43-, NO3-, Total Coliform, Temperature, and EC. Comparing water quality with water quality standards in the five watersheds shows that several samples exceed the standard. WQI result shows that all river water in the five watersheds belongs to the excellent classification. A different result from the PIj index shows that the five watersheds were dominantly moderately polluted, with several samples considered polluted and extremely polluted. Differences in the index formula and water quality standards cause these different results. The results of the analysis show that the PIj index is more representative than the WQI as the PIj index shows the suitability of the classification comparison of water quality values with water quality standards compared to WQI.

Abstract

One of the indicators of land productivity assessment is soil fertility. The causes of infertile soil have been widely reported. This study aimed to evaluate soil fertility using the Soil Fertility Capability Classification (SFCC) approach and to determine the relationship between soil morphological and physiochemical properties and soil fertility. The research was conducted in North Galela Sub-district, North Halmahera Regency. The research framework began with the interpretation of thematic maps, surveys, field observations, and the making of soil fertility evaluation maps. Soil sampling was carried out based on the stratified random sampling method and supported by laboratory measurements according to USDA international standards. The research result showed that the research area had 14 soil fertility statuses. The fertility classes having the most significant limiting factor were loamy texture (Ø<0.002 mm), rock surface, gravel subsoil, moderate salinity (0.2-0.4 mS cm-1), low exchangeable K (<20 cmol(+) kg-1), and sloping slope (8%) with Lithic Haprendolls type and loamy texture (Ø<0.002 mm), subsoil >15% rock outcrop, moderate salinity (0.2-0,4 mS cm-1), Na saturation >15%, and a rather steep slope (14%) with Lithic Eutrudepts type. Both of these classes have a top layer texture, and the bottom layer contains clay <35%, with limiting factors of hard layer inhibiting root to a depth of 50 cm, extremely low nutrient reserve, low electrical conductivity (EC) and high Na. The limiting factors found in North Galela Sub-district were hard root-restricting layer, exchangeable K, electrical conductivity, Na saturation, slope, and gravel.

Abstract

The Upstream Citarum watershed has a critical essential role in maintaining the quality and quantity of its water resources, which are a source of drinking water, agriculture, fisheries, irrigation, and electricity generation. The upstream watershed acts as a water catchment area that contributes as a place to accommodate the availability of water, especially during the dry season, and also as a protector of the entire area, both downstream and middle, so that the carrying capacity of the ecological balance can be protected. The increasing total population was inversely related to the condition of land use which is decreasing in quality, so to fulfill these needs, there was a land conversion that caused changes in land use. The Landsat-8 satellite imagery, SPOT 7, and spatial planning maps were used to analyze the suitability and incompatibility of land use with spatial pattern plans, evaluation, and directions for controlling the use of space. The result of the most extensive existing land use in the Upstream Citarum watershed in 2021 used for fields is 30% of the total area of 66,831.66 ha. Meanwhile, the spatial pattern plan was classified into protected and cultivated areas. The built-up area has the largest area, 35% or 75,223.96 ha. The results of the suitability of land use classes obtained that the level of suitability between the existing land use and the spatial pattern plan from the Maps of Regional Spatial Planning with the appropriate class was 52.50% or 96,205.43 ha, and the unsuitable class was 47.50% or 87,028.75 ha.

Abstract

A biodegradable seedling container was developed to minimize plastic waste in the field during post-mining land revegetation activities. Therefore, this study aims to evaluate the physiological response and growth of Samanea saman grown in a biodegradable seedling container filled with post-silica mined soil media. A factorial experimental design was used with two factors, namely (1) basic raw materials, namely recycled newspaper, compost, and cocopeat, and (2) size of raw materials, including 5 mesh, 10 mesh, and 8 mesh. The parameters measured were photosynthetic rate, leaf greenness index, transpiration rate, height, and diameter of S. saman seedlings. The results showed that the interaction between the composition and size of basic raw materials of the biodegradable seedling container significantly increased the photosynthetic rate, leaf greenness index, transpiration rate, height, and diameter of seedlings. There was also a positive correlation between the rate of photosynthetic and leaf greenness index (r = 0.838). Furthermore, the C/N ratio of the biodegradable pot varied depending on the composition of materials used. After two months, the C/N ratio decreased, indicating that decomposition processes had occurred. Analysis of the biodegradable seedling container showed that it contains less than 0.08 mg Pb kg-1, which was considered a non-toxic element for plant growth.
