Abstract

Banana is one type of fruits that is very potential to grow to support food security because it contains source of vitamins, minerals, and carbohydrates. Jenawi District has a dry land area that is potential for the development of banana plants. The purpose of this research was to plan the development of banana plants in accordance with the land conservation aspect against the threat of the erosion. The research was conducted by making land unit map, field survey, analysis of soil sample in the laboratory, and data analysis of erosion hazard level. Land unit mapping was made by overlay method so there were 12 units of land with the same land conditions. Field survey and sample analysis at the observation point was conducted to obtain the parameters: slope gradient, depth of solum, surface unity, slope length, bulk density, soil texture, soil c-organic, and soil permeability. The analysis of land conservation aspects for banana plants was determined from the level of erosion hazard with the USLE (Universal Soil Loss Equation) method. The results showed that the threat of moderate to severe erosion hazard for banana crops was overcome by the efforts of land conservation techniques using a good construction bench terrace. The threat of erosion hazard after land conservation directives is very low to low. The amount of the erosion prediction for banana plant planning in garden is 35.80 t/ha/yr (unit B unit), land use of dry fields  is 29.82 t/ha/yr (land unit I), 31.54 t/ha/yr (land unit K), and 13.72 t/ha/yr (unit land L).

Abstract

This research was conducted with the aim of studying land use change and evaluating the impact of land conversion on land capability in Tirtomoyo District of Wonogiri Regency. This research employed a descriptive, explorative method by utilizing SIG Arc Map 10.1 and Google Earth Pro software. The analysis of land use change, especially agricultural land, was conducted through visual interpretation of Google Earth Pro satellite imaging in 2004 and 2016. A ground check was done by land survey. Soil sample analysis was done to determine land capability class. Based on research results, it was found that eight locations experienced land use change. Location 1 had changed from secondary forest to moor, location 2 from moor into farm, location 3 from bushes into paddy field, location 4 from paddy field into farm, location 5 from paddy field into farm, location 6 from moor into paddy field, location 7 bushes into moor, and the location 8 from paddy field into farm. Land use changes showed different results of changes in soil physical properties based on soil characteristics at each type of land use. Changes in land use generally had less impact on land use class change. Locations 1, 6, and 7 did not experience changes in land capability class, but there were changes in the sub-classes of land capability. Locations 2 and 8 did not experience changes in class or sub-classes of land capability but sites 3, 4, and 5 indicated changes in land capability class by inhibiting factors namely permeability class in a paddy field.

Abstract

The demand for shallots is getting higher as the population grows. Indonesia targets to become a self-sufficient country of onion and the largest exporter of shallots in ASEAN by 2045. One of the shallot production centres is Losari District, Brebes, but the shallots productivity has decreased, so it is necessary to know the cause and the improvement effort to overcome it. The research was a land survey and evaluation to determine the current and the potential land suitability classes for the shallot. Data analysis using LMU (Land Map Unit) as the unit of analysis, which is the result of an overlay of soil type map, slope map and land use map using ArcGIS 10.3. The sampling method was purposive sampling and data analyzed using the matching method between the results of land characteristics data with the requirements of shallots growing. Results showed that even in production centres, the current suitability classes are marginally suitable (S3) as the heaviest limiting factors are very high rainfall. Improvement efforts to overcome this can be done by using suitable varieties, making gully drainage and using mulch/shade so that the potential land suitability class increases to be moderately suitable (S2).

Abstract

Environmental degradation, which is caused by the quarry, is a complex problem. The site of the quarry within an agricultural land and forest makes land become critical. Rehabilitation of the area can be conducted by reclamation. Revegetation using local species is no better than pioneer species. Based -on Indonesian regulation-in Permenhut P.4/Menhut-II/2011, revegetation using fast-growing species is important for a precondition before enrichment using climax species, so then it needs an evaluation of land suitability for the fast-growing species. The study of revegetation was conducted at quarry clay which the characteristics of this study were description and exploration with field survey supported by laboratory analysis. Data obtained were analyzed by giving weights and scores of species characteristics to decide selected species of vegetation, then the soil characteristics and qualities were matched with species growth requirements. The results showed that jabon (Anthocephallus cadamba) and sengon (Falcataria moluccana) are selected species for revegetation. Land suitability classes of jabon and sengon are not suitable (N) and land suitability of jabon and sengon can be increased to be marginally suitable (S3) by reclamation using potting system that includes building drainage, improvement of depth, soil pH, application of fertilizer, dolomite, and gypsum, application of grass mulch and collecting large rocks for making the terrace.

Abstract

This study aimed to determine the status of soil damage in Pitu District, Ngawi Regency. The study was conducted in a descriptive exploratory with survey methods. Determination of site sampling was done by purposive sampling, based on distribution or division and land use categories from the results of map overlays. Assessment of soil degradation potency was based on land units from the uniformity of the soil, rainfall, slope, and land use map. Land units resulting from overlay were scored based on the results of multiplication of weights and soil, slope, rainfall, and land use ratings. Total score indicates soil Degradation Potency (SDP). Assessment of soil degradation status was done through matching and scoring. Field observation results were matched with the standard criteria of soil degradation from Indonesian Government Regulation No. 150 of 2000. Each parameter was scored, then the total score was used to determine soil degradation status. Soil degradation potency in Pitu District, Ngawi Regency is PR II (Low) at LMU (Land Map Units) 1, 3, 4, 5, and 8, and PR III (Moderate) at LMU 2, 6, 7, 9, and 10. Soil degradation status in Pitu District, Ngawi Regency is slightly degraded at all LMU, with limiting factors, namely texture, bulk density, total porosity, and permeability.
