Abstract

This study aimed to evaluate the effects of soil amendment and phosphorus fertilizer application techniques on the chemical properties of dry land Vertisols, P absorption efficiency by maize and maize yield. The study was conducted on farmer's land located in Noelbaki Village, Central Kupang District, Kupang Regency, East Nusa Tenggara, Indonesia. The study was conducted during two planting seasons, namely the rainy season 2020/2021 (PS-1) and the dry season 2021 (PS-2). The soil used in this experiment was included in the degraded Vertisols. This study used a split-plot design with three replications. The main plot was the type of organic soil-amendment material, and the subplot was the technique (dose and stage) of applying phosphorus fertilizer sourced from SP-36. The results showed that organic soil amendment and phosphorus fertilizer application techniques could improve soil chemical properties, P uptake, P absorption efficiency and maize yield in Vertisols until the second planting season. In the long term, the combination of maize stover biochar and the technique of applying phosphorus fertilizer (P3-T2) significantly increased the P uptake by 32.31 kg ha-1 (PS-1) and 31.23 kg ha-1 (PS-2), the P absorption efficiency by 28.65% (PS-1) and 27.75% (PS-2). The P3-T2 treatment gave maize yields of 6.92 t ha-1 (PS-1) and 6.92 t ha-1 (PS-2), which were higher than those of other treatments.

Abstract

Manganese (Mn) is one of the heavy metals found in industrial wastewater, such as acid mine drainage, which has caused serious environmental problems worldwide. This equilibrium study was carried out to determine the maximum capacity of natural zeolite towards manganese removal from made aqueous solution as affected by zeolite quantity, particle size, activation temperature, and initial pH of the solution. The natural zeolites obtained from Tasikmalaya, West Java, Indonesia, were crushed and filtered into three groups of diameters: <0.5, 1-2, and 2-4 mm. Each group was divided into two sub-groups, one sub-group was heated in a muffle furnace at 250 oC for two hours, and the other sub-group was left at room temperature (25 oC). This experiment consisted of two sections. Section one was physical and chemical characterizations of the natural zeolite, using Scanning Electron Microscopy (SEM), X-Ray Diffraction, and X-Ray Fluorescence techniques. The second section was equilibrium studies using two series of 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, and 5 g of natural zeolites of each sub-groups, then respectively added with 50 mL of a solution containing 50 ppm Mn having pH of 5.5 and 7.0. All suspensions were shaken for 24 h and filtered. The filtrates were red for total dissolved Mn using Atomic Adsorption Spectrophotometer (AAS). Freundlich and Langmuir isothermic models were fitted to the collected data to describe the adsorptive behaviour of Mn toward natural zeolites. Data showed that 0.5 g of natural zeolite had removed the remarkably highest Mn from the solution, regardless of the size of the particles, thermal treatment, and initial solution pH. The smallest size of zeolite particle and higher initial solution pH tended to increase the adsorptive capacity of the natural zeolite toward Mn. The Freundlich isothermic model fitted better to Mn adsorption behaviour than the Langmuir model.

Abstract

Like other natural resources, groundwater is also being exploited at an increasing rate, especially for domestic requirements. Groundwater is preferred as a domestic water source because of its continuous availability and relatively good quality. Unfortunately, not all places have sufficient groundwater availability of good quality. The purpose of this study was to analyze the characteristics of the aquifer in the study area and evaluate its groundwater potential for domestic needs. Aquifer characteristics were determined based on geological and geomorphological conditions, while groundwater potential was calculated using a static approach. The results showed that the characteristics of the aquifers in Kediri Regency are various. In the eastern and central parts of the study area, the characteristics of the aquifer can be in the form of unconfined aquifers with high productivity. In the western part, most of them have non-aquifer material, so it is difficult to find groundwater. Groundwater generally fills joints and diaclase formed in andesitic lava with low discharge. Although the conditions of the aquifer are various, in general, the potential for groundwater in Kediri Regency can still support its requirements because the potential for groundwater in Kediri Regency is 71,121,313,394 m3, while domestic requirements is 52,348,490 m3/year.

Abstract

Humic acids play a crucial role in ion exchange and metal ion complexes; therefore, they are potentially useful in improving soil fertility and crop yield. This study aimed to explore the role of humic acid (HA) from various composts in improving degraded soil fertility and maize yield. A field experiment was conducted on Inceptisols having low soil organic carbon, nitrogen and available phosphorus contents. Eight treatments of HA formulas and one control were arranged in a randomized block design with three replications. The HA formulas used were combinations of two doses of HA (0.15 and 0.20% of soil on w w-1 base) and four types of HA (HA extracted from bagasse compost, HA extracted from water hyacinth compost, HA extracted from market waste compost, and commercial HA). The results showed that the HA application increased 16-97% of soil organic carbon, total nitrogen, available phosphorus, exchangeable potassium and calcium compared to the control. The formula of commercial HA at 0.15% was the best treatment for inhibiting soil fertility degradation in agricultural land. The best maize yield of 15.13 t ha-1 and starch content of 63.54% was obtained from the application of commercial HA at 0.20%.

Abstract

Ex-coal mining void has changed landscape shape, physical-chemical, and soil biological properties. As a form of post-mining management, the company must restore damaged land and increase its benefits for the surrounding community, one of which is as a freshwater aquaculture area. This study was conducted in a 50.26 ha void in the concession area of the coal mining company PT. Mitrabara Adiperdana (MAP) in Malinau Regency, North Kalimantan. The method used is by examining the physical quality of the environment in the laboratory using the quality standards in Indonesian Government Regulation (PP) No. 82 of 2001 and No. 22 of 2021. A study was also conducted on the assessment of community acceptance. The study found that freshwater aquaculture for pangasius (Pangasius sp.), snakehead (Channa striata), and tilapia (Oreochromis sp.) is appropriate to apply on location with several notes: reducing the concentration of suspended solids; reducing the content of phosphate and ammonia, and reducing the concentration of lead (Pb). Regarding these issues, two methods can be used: technology of turbine and nanobubble and natural-based solution through wetland ecosystem and void basin rehabilitation. At the same time, education and promotion of the surrounding community can be applied by involving communities during the piloting and demonstration plot process.

Abstract

This study aimed to evaluate the type of floor in the composting process of leaf wastes. The waste consisted of cacao leaves (Theobroma cacao L.), rubberwood leaves (Hevea brasiliensis), teak leaves (Tectona grandis L.f), matoa or Fijian longan leaves (Pometia pinnata), durian leaves (Durio zibethinus), and grass. The research was conducted by composting the leaf mixtures in a composting box sizing 220 cm in length, 180 cm in width, and 100 cm in height. A long box was partitioned by using plastic tarpaulin into four boxes for different floors, namely cement, soil, tarpaulin, and rice husks. A mixture of leaves of 127 kg to 176 kg was introduced in each box and was composted for 145 days. Variables observed were temperature, the height of heap, the mass of material (initial and final), C/N ratio, NPK contents, compost color, odor, pH, and moisture content. The results showed that compost quality fulfilled Indonesian National Standard (SNI 19-7030-2004) regardless of the floor types. However, the type of floors affected the compost process and yield. The composting process with tarpaulin-layered or husk-layered floors produced better compost in terms of N, P, C/N ratio, and color as compared to those resulting from cemented or barely soil floors.

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.
