Mulyono, Maas A, Purwanto BH, Sudira P. 2018. Short Communication: Volcanic ash utilization as planting medium of curly lettuce with charcoal husk and urban waste compost as soil amendment. Asian J Agric 2: 39-43. During a volcanic eruption, volcanic ash spreads over an extensive area, causes environmental disturbances, and thus, should be disposed afar from settlements. On the other hand, volcanic ash is useful in urban areas where pot-planting is often lack soil medium. However, the utilization of volcanic ash as direct planting medium has many obstacles due to its characteristics such as the acidic, nitrogen nutrients rareness, compressed and dull to water. Hence, to be ready to use, it should be improved by using soil amendment. This study used charcoal husk combined with compost as the soil amendment. The purpose of this study was to use the volcanic ash as the planting medium, by obtaining a proper dose of volcanic ash and the soil amendments for the growth and yield of curly lettuce. The experimental design applied in this study was the complete randomized design (CRD) with three replications. The first factor was the 5 levels of charcoal husk (on volcanic ash) doses, namely 0.30; 0.40; 0.50; 0.60; and 0.70. The second was the ratio between the media and the 3 levels of urban waste compost doses, namely: 3:1; 2:1 and 1:1, resulting in 5 x 3 total combinations with three replications. The plant growth and yield data results were analyzed by using the variance analysis and continued with Duncan Multiple tests (Duncan Multiple Range Test). The results showed that when used as the sole planting medium, the volcanic ash could not support the growth of lettuce plants. The evidence was shown from the same size and weight of the curly lettuce after the age of 35 days (5 g/plant). The utilization of husk and urban waste compost treatment showed significant growth rise. The combination of volcanic ash and soil amendments showed that the best effect on the growth and yield of curly lettuce was from M3K3 treatment at the dose of 25% volcanic ash, 25% charcoal husk and 50% urban waste compost (60 g/plant).

Abstract

Along with the development of the tourism in Bali, one of the phenomena occurs was that the land conversion to the non-agricultural land, causing the canal irrigation was not able to function again. In addition, water demand will be increased not only for irrigation, but also for other sectors out of irrigation. This condition can interfere the performance of the subak system. One strategy to improve subak system is to develop agroecotourism based on subak system. Analysis of physical performance subak system done using fuzzy logic approach to quantify the condition of vagueness. Because of the problems associated with subak irrigation systemperformance are often vague and can not be classified with certainty. The results of this study are (i) the values of subak irrigation system performance indicators, the condition and thefunction of subak irrigation facilities, the condition and the function of subak facilities, and the agroecotourism facilities; (ii) find out the physical performance of subak irrigation systems in Bali with agroecotourism oriented. The stages of this research were collecting and analyting the data include: (i) RWS (Relative Water Supply), (ii) RIS (Relative Irrigation Supply),(iii) Ia (Index Area), (iv) analysis of the condition and function of subak irrigation networks, (v) the condition and the function of subak facilities, (vi) the agroecotourism facilities, and (vii) physical performance of subak system using fuzzy logic approach. The utilization rate of water on Subak Anggabaya and Subak Lodtunduh in one year was good. Subak Anggabayaand Subak Lodtunduh have sufficient irrigation water supply with RIS values in one year > 1. Based on Area Index (Ia), it could be seen that the irrigated area in Subak Anggabaya andSubak Lodtunduh in accordance with the plan. The physical performance of Anggabaya subak system and Lodtunduh Subak system was in the middle criteria.

Abstract

Study on meteorological water balance in Keduang watershed, Central Java, aimed to find a balance between the need and meteorological availability of water in the Keduang watershed. Water demand is calculated by using the standard water requirements for this type of irrigation and non-irrigation needs. Types of non-irrigation water requirements include the need for water for domestic, office buildings, health facilities, lodging / hotels, educational facilities, religious facilities, industries, and markets, as well as livestock. Standards need water used is ISO 19-6728.1-2002 and Planning Criteria DGHS Department of Public Works in 1996. The availability of water is calculated using the water balance approach meteorological Turc-Langbein. The data used is the data in 2013 and analyzed using quantitative description.The results showed that 1) the need for water in the Keduang watershed 81,063,567.42 m3 / year, while 2) the availability of water in the meteorological amounted 280,160,992.62 m3 / year so that the difference amounted to 199,097,425.19 water m3 / year. From the results of these calculations, we can conclude that the water availability in the Keduang watershed is sufficient for fullfilling the water requirements.

Abstract

Land is a natural resource with a limited number so that the utilization of this resource should consider its ability to be able to produce sustainably. Inappropriate use may result in land degradation as indicated by the amount of erosion. This study aims to (1) evaluate the land use capability (LUC) classes and their conformity with the actual land use, (2) determine the impact of mismatches between the LUC classes and actual land use on erosion. Study was conducted in Tapan and Ngunut I Sub-Sub-watershed, Karanganyar District, Central Java. Universal Soil Loss Equation (USLE) was used to predict the potential erosion on the area while modified FAO method was used to analyze LUC. The results showed that the percentage of disagreement between LUC class and with actual land use in Tapan was 23% while in Ngunut was only 0.02%. The percentages of those disagreements have no effect on the magnitude of the annual erosion. Annual erosion in Tapan (15.12 tonnes / ha) is still smaller than in Ngunut I (25.63 tonnes / ha). Composition of land cover types and land management affect the amount of erosion. Cultivation of crops at dry land and land tillage during growing season in accordance with the rainy season has great contribution on erosion. Keywords : Unsuitability, land covers, LUC, erosion
