Abstract

The natural zeolite was treated with alkali (NaOH) solution and heating at 100 oC for 12 and 24 hours. The natural zeolite was collected from Gunungkidul, Jogjakarta, Indonesia. The series of NaOH solutions was 0.5, 1.0, 1.5, 2.5, 3.5 and 4.5 M. The final product of the reaction (precipitate) was designated as 'activated natural zeolite (ANZ)'. The cation exchange capacity (CEC) of the ANZ increased with increasing NaOH concentration up to 1.5-3.5 M. Treatment with NaOH 3.5 M and 12 hours in period of hydrothermal reaction resulted in a maximum CEC (395.6 cmol.kg-1). The maximum CEC also observed for treatment with NaOH 1,5 M, but consumed a longer time (24 hours). The increase in the CEC of the ANZ about 300 % higher than the original one. The XRD (X-ray Diffraction) peaks of the ANZ appear at 2.7, 3.2, 4.1, 5.1, 7.2 Ã…, this indicated a new crystalline matters (possibility phillipsite) present. Electron micrograph showed that the ANZ has a large cubic/prismatic structure with a perfect form.

Abstract

Rice quality is the dominant factor of rice. The quality of rice includes the weight percentage of head rice, amylose content and the quality of rice include flavor of rice, rice texture and rice aroma. Rice from different rice varieties will be different quality, so also the way of rice cultivation is also very influential on the quality of rice produced. This study aims to compare the quality of rice from various rice varieties under organically and conventional cultivations. The experiment was conducted on Organic and Conventional rice field in Kebonagung village, Imogiri, Bantul from September 2013 until January 2014 with Inceptisol soil type and altitude of 114 m . This research was designed with Randomized Completely Randomized Block Design which was arranged in a split plot consisting of 2 treatment factors and repeated 4 times. Factor I: Cultivation, namely organic cultivation and conventional cultivation and Factor II kinds of varieties that consist of IR64, Cianjur, Pandanwangi, Mentikwangi and Cisedane. Parameters observed included grain yield, percentage of rice head, amylose content, protein content, and rice quality including rice flavor, rice texture, and rice aroma. The results showed that (1) the yield of grain did not differ between organic cultivation and conventional cultivation. (2) Organic cultivation increased the heavy percentage of rice head of IR64 variety, (3) Organic Cultivation decreased the amylose content of Cianjur and Pandanwangi varieties, and increased the amylopectin level so the rice became more “Pulen” (4) Organic cultivation raises levels of IR64, Pandanwangi, Mentikwangi and Cisedane variety of varieties, (5) Organic cultivations tend to improve the quality of rice including taste, texture and aroma of rice

Abstract

Boron (B) is an essential micro nutrient that is needed by oil palms, especially to control productivity. The aim of this research was to determine the optimal dose of B for mature oil palms. The research was conducted at a smallholder oil palm plantation located in Katingan Region, Central Kalimantan Province from January to December 2022. The field experiment was a single factor arranged in a Randomized Complete Block Design (RCBD) with three blocks as replications. The factor tested was the dose of B fertilization, consisting of five doses, namely 0 g. trunk⁻¹. semester⁻¹ (control); 25 g. trunk⁻¹. semester⁻¹; 50 g. trunk⁻¹. semester⁻¹; 75 g. trunk⁻¹. semester⁻¹; and 100 g. trunk⁻¹. semester⁻¹. Observations were done on several variables of micro-weather characteristics at the research site, nutrient and physiological characteristics of leaf, morphological characters and plant growth, and yield and yield components of oil palms. The data obtained were then analyzed with analysis of variance (ANOVA) α=5 %, and data showing significant differences between treatments were tested with an orthogonal polynomial. The results showed that B had positive effects on leaf B, P and K concentration and absorption, leaf chlorophyll content, number of midribs, plant height, leaf area per trunk, leaf area index, crop dry weight, pollen fertility, fruit set, pollen viability, fresh fruit bunch weight (FFB) and FFB productivity. The optimal dose of B to optimize oil palms productivity was 60.24 g. trunk⁻¹. semester⁻¹ with a maximum value of FFB productivity of 6.94 tons. trunk⁻¹. semester⁻¹.

Abstract

A coastal rice field is generally characterized by salt-affected soil and low soil quality for rice cultivation. Identifying soil chemical properties in these areas is necessary to determine soil management options for rice production. Therefore, soil samples were collected from 33 sampling points in the Wedung Sub-district of Demak Regency in the late dry season of 2021 to evaluate the variation among soil chemical characteristics in a coastline rice field. Soil samples were obtained beneath the topsoil (0-20 cm soil depth) and observed for electrical conductivity, exchangeable potassium, sodium, calcium, magnesium, and cation exchange capacity. Soils in the research field were categorized as slightly salty (0.75-2 dS m-1) to lightly salty (2.0-4.0 dS m-1) with very high sodium (>2 cmol(+) kg-1). Exchangeable potassium was dominated by moderate (0.3-0.7 cmol(+) kg-1) and low categories (0.2-0.3 cmol(+) kg-1). Based on soil calcium-to-magnesium ratios, around 6% of all samples were classified as calcium-deficient. The range of soil cation exchange capacity was 22-30 cmol(+) kg-1 and classified as high soil cation exchange capacity. Rice productivity in the salt-affected soil was around 4 t ha-1. Strategies for soil and controlling plants, such as soil amelioration and salt-tolerant rice cultivars, should be pursued to support plant growth and enhance rice productivity in the salt-affected soil, particularly in the coastal area.

Abstract

The combination of fertilizer treatment with biochar has shown to be a sustainable and ecologically friendly method of increasing soil fertility and crop productivity. However, its combined impact on nutrient availability and rice yield is still unclear. This study aimed to investigate the effect of bamboo biochar produced by the Kontiki method in combination with nitrogen and phosphorus fertilization on nutrient availability in the soil and the productivity of rice. The treatment factors included the fertilizer combination factor (B) consisting of B1 (N + P fertilizer + Biochar), B2 (N fertilizer + Biochar), B3 (P fertilizer + Biochar), and B4 (Biochar + no fertilizer), and the biochar dose factor (F) comprising F0 (0 tons ha⁻¹), F1 (5 tons ha⁻¹), and F2 (10 tons ha⁻¹), resulting in 36 experimental plots with 12 treatment combinations. Measurement of ammonium and nitrate concentration in the soil started on the 15th day after planting, following the measurement of the growth of rice plant biomass with an interval of 15 days. The measurement of available P in the soil was started on day 45 after planting and continued until harvesting time with the same time intervals as the measurements of ammonium and nitrate. The study found that combining bamboo biochar treatment with nitrogen and phosphorus fertilizer greatly boosted the availability of nitrogen (ammonium and nitrate) and availability of P in the soil. Treatment combinations improved lowland rice yield (P < 0.05) by increasing plant height, number of tillers, dry weight of shoots and roots, grain weight per clump, 1000-grain weight, and grain yield.

Abstract

Soil fertility is enhanced by eruptions of Mount Merapi, which deposits pyroclastic debris rich in weatherable primary minerals. Therefore, this study aimed to assess the geochemical weathering index of soils in the southern catena of Mount Merapi, an area affected by the 2010 eruption. Soil samples were collected to describe 4 geomorphic units, namely the higher, middle, lower, and foot slopes. X-ray fluorescence (X-RF) was conducted to determine total element content, and five weathering indexes (Weathering Index of Parker (WIP), Vogt's Residual Index (V), Chemical Index of Alteration (CIA), Chemical Index of Weathering (CIW), and Plagioclase Index of Alteration (PIA)) were calculated. The results show that aluminum (Al) was the most abundant oxide, followed by calcium (Ca), potassium (K), magnesium (Mg), and sodium (Na). Weathering indexes suggested moderate weathering (WIP > 100, V > 1) with a significant presence of fresh volcanic material (CIA, CIW, PIA between 50-100, closer to 50). Variations in each horizon signified the vertical and horizontal movement of mobile elements. The C horizon (deeper layer) had a higher WIP but lower values for the other indexes. In conclusion, geomorphological units influenced the distribution of fresh volcanic material, weathering products, and translocation of elements. Weathering index values reflected the ongoing release of nutrients from minerals. This information was crucial for developing nutrient management strategies in the Merapi region.Received: 2024-04-26 Revised: 2024-06-21 Accepted: 2025-02-19 Published: 2025-02-25
