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 Å, 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

The eruption of Mount Merapi had been giving adverse effect for the community, but on the other hand, there are great benefits in it such as the enrichment back to the land. Enrichment process in land with materials that are rich in nutrients is often known as rejuvenation. In general, the rocks containing certain minerals or mineral assemblages, which has large amount of the potential nutrient that can be used by plants in the form of weathered minerals. Therefore, it is a big question about the relationship between primer mineral deposits on Mount Merapi volcanic material with the potential nutrient for crop. The results showed that the identification of Merapi pyroclastic material derived from basaltic andesite magma with primary mineral content easily weathered the dominant form of plagioclase. Utilization of volcanic material as macromineral is easy to use, because the nutrient content of the existing potential in minerals included in the group of minerals that easily weathered.

Abstract

Oil palm is one of intensively planted in Indonesia, large-managed for industrial oil palm. This study aimed to know the influences of urease and nitrification inhibitor on loss of N and oil palm harvest in peat. The research was conducted at Sukamandang Village Coconut Plantation, Seruyan Tengah District, Seruyan Regency, Central Kalimantan Province. The research used a single factor of field experimental method with Randomized Completely Block Design (RCBD). Urea and ZA fertilizer were used in this study with the following treatment: N0= Without N, N1= Urea (195 kg.ha-1 N), N2= Urea + 0.12% NBPT-NPPT (195 kg.ha-1 N), N3= Urea (156 kg.ha-1 N), N4= Urea + 0.12% NBPT-NPPT (156 kg.ha-1 N), N5= Ammonium Sulfate (427 kg.ha-1 N), N6= Ammonium Sulfate + 0.8% DMPP (427 kg.ha-1 N), N7= Ammonium Sulfate (324 kg.ha-1 N), N8= Ammonium Sulfate + 0.8% DMPP (324 kg.ha-1 N). The research result indicated that the use of NBPT and DMPP inhibitors did not affect N levels in the leaves and the free fatty acids. Urea + NBPT treatment had no N loss for about 30%–50% which was lower than urea without N, whereas ammonium sulfate + DMPP had smaller N loss than all treatments without N fertilization. Fertilization using urea + NBPT and ammonium sulfate + DMPP increased the production of FFB and yield of oil palm.

Abstract

This study investigated the effectiveness of mycorrhizal fungal multi-spores and inorganic fertilizers in increasing NPK uptake and growth of maize on ombrogenous peat soils in Riau. The experiment, which was carried out in a plastic house, was arranged in a completely randomized design (CRD) with two factors, consisting of five replications. The first factor was the application of mycorrhizal fungal multi-spores, consisting of two levels (with and without application). The second factor was the application of inorganic fertilizer, consisting of three levels (P0: without fertilizer, PM-1: mixture of 225 kg Urea + 100 kg SP-36 + 75 kg KCl + 1000 kg Dolomite, and PM-2: mixture of 450 kg Urea + 200 kg SP-36 + 150 kg KCl +2000 kg Dolomite). Observed data consisted of agronomic observations, soil observations, and mycorrhiza observations. Agronomic observations consisted of plant height, root dry weight, shoot dry weight, and N, P, K nutrient uptake, and soil observations consisted of total and available N, P, K nutrients in the soil. Meanwhile, mycorrhiza observations consisted of infected roots and spore populations. The data obtained were then analyzed using DMRT to see the significant effect of the treatments. There was no interaction effect of mycorrhiza and compound fertilizer on the variables of shoot and root dry weight, but the interaction effect was observed on the variables of of shoot N, P, K uptake and root P and K uptake.

Abstract

Vegetation recovery is essential in land restoration after the eruption of Mount Merapi in 2010. Vegetation is a source of organic material that produces root exudate containing organic acids. These acids accelerate the dissolution process of volcanic material so that it affects the soil characteristics. This study was conducted to analyze the effect of four types of perennial plants on soil chemical and physical characteristics. The soil samples were taken on the area planted with cinnamon, albizia, bamboo, and acacia, at depths of 0 – 10 cm, 10 – 20 cm, 20 – 30 cm, 30 – 40 cm, and 40 – 50cm. The soil chemical analysis carried out included pH H2O, pH KCl, pH NaF, C-organic, Humic acid and Fulvic acid, cation exchange capacity, Ca, Mg, K, Na, available P, base saturation, and particle size distribution. The results show that pH H2O, pH KCl, C-organic, humic acid and fulvic acid, CEC, K, Na, Ca, Mg, available P, base saturation, and particle size distribution were significantly affected by vegetation type. Meanwhile, the pH of NaF was not significantly influenced by vegetation type. Cinnamon is a plant that gives the strongest influence in the improvement of soil chemical-physical properties compared to the other three types of vegetation. Therefore cinnamon is quite prospective plant to be developed for post-eruption land reclamation.

Abstract

Rice production can be improved through extensification using sub-optimal lands. One type of land that can be used for extensification of rice production in D.I. Yogyakarta is eucalyptus agroforestry system in Playen, Gunung Kidul. Besides expanding the land use, it can also increase farmers’ income and ecological functions. However, this system has limiting factors such as the limited availability of water, which only relies on rain. Thus, proper water management and fertilization are necessary to fulfill water and nutrient requirements for rice growth. This study aimed to determine the effects of the application of trenches with organic matter and the doses of KCl on the growth and yield of upland rice (Situ Patenggang) in eucalyptus agroforestry systems. The study was conducted at the Menggoran Forest Management Resort, Bleberan, Playen, Gunung Kidul in March-August 2018. The study was arranged in a split-plot design with three blocks as replications. The first factor was the application of trenches with organic matter, while the second factor was KCl fertilizer at. various doses. The data obtained were analyzed using analysis of variance (ANOVA) at the level of 5%. The optimal dose of KCl fertilizer was determined by regression. The results showed that both factors had a positive effect on soil moisture content, growth, physiology, and yields of upland rice. The treatments significantly increased the availability of water in the soil, thereby supporting the growth and yield of upland rice.

Abstract

The expansive ability of soil causes a series of problems in various sectors. The dominance of smectite clay minerals significantly affects expansive ability because they have an unstable interlayer structure. Cation intercalation and calcination is a treatment method that can increase the stability of the clay interlayer structure. This research investigated the effects of intercalation cations and calcination treatment on the swelling ability and cracking properties in the clay from vertisols; the cations used for intercalation were aluminum and iron. The intercalation tested doses were based on the equivalent weight of 0x, 0.5x, and 1x cation exchange capacity (CEC) clay value. The calcination treatments used were 200°C, 300°C, and no calcination. Each treatment interaction was repeated three times. Parameters observed were the total area, average crack width, average lump area, total number of lumps, moisture content, swelling volume, and pH after treatment. The results showed that each treatment had a significant effect. Clay with an Al intercalation dose of 1x CEC without calcination treatment had the highest total area after drying, which was 41.035 cm2; the lowest average crack width was 0.153 cm, and the smallest swelling volume was 3.6 cm3. In contrast, the clay without intercalation and calcination treatments had a swelling volume up to 10 cm3 on the 7th day. The clay with an Al intercalation dose of 1x CEC with 200°C calcination exhibited the best results in reducing the expansive clay ability and can be used as a guideline for further testing to reduce the soil’s expansive ability.
