Abstract

Development is a changing process to improve human standard of life that strongly related to the activities of natural resource utilization. It is frequently found that these activities  change the ecosystems and their resources.  Eventually, these changes will give serious impacts to the environments. The most distinct environmental problems are caused by resident migration to the coastal areas, coastal developments, and land limitation. Coastal reclamation is an example of human effort to respond to the land limitation in the coastal areas as observed in coastal areas of Labakkang Subdistrict. Reclamation activity is doing along the coast of Pundata Baji Village, whereas, in other villages, cutting off of mangrove areas as an alternative land expansion is increasingly practiced by the local communities. This Research was aimed to observe the landscape change from 1980 to 2010 at coast area in Labakkang Subdistrict. Each review considers Landsat Image Map (acquired in 1980); Landsat Image Map (acquired in 1990); Landsat  Image Map-7 Enhanced Thematic Mapper Plus (ETM+) (acquired in 2000); Spot Image 4 (acquired in 2005); and Spot 4 LAPAN (acquired in 2010). Result of research indicates that at coast area of Labakkang Subdistrict in 1980, there are 248.3 ha of mangrove vegetation, 2,756.63 ha inundation, and 4,157.0 ha open land. In 1990, there are 234.2 ha mangrove vegetation, 2,251.63 ha embankment, 933.2 ha rice field, and 582.0 ha open land. In 2000, there are 218.3 ha mangrove vegetation, 2,848.1 ha embankment, and 3,579.2 ha rice field. In 2005, it has 121.4 ha mangrove vegetation, 3,762.6 ha embankment, and 2,306.2 ha rice field. In 2010, it is found 48.9 ha mangrove vegetation, 5,029.35 ha embankment, and 749.98 ha rice field.

Abstract

Cajuput oil production process in PMKP Sukun produce cajuput oil and waste. There are three types of waste generated, ie liquid waste, solid waste, and gas waste. Solid waste in the form of waste of cajuput leaves is mostly used for briquettes and sold crude and the remaining is unutilized. To reduce the very high volume, so the unutilized solid waste is used as added fertilizer to planting media of cajuput seedling. This study was conducted to determine the effect of treatment of leaves waste compost of cajuput oil (bokashi) on the growth of seedlings of cajuput plants (Melaleuca cajuputi Powell). The method used was a randomized block design consisting of nine treatments and three replications with the observation parameters of seedling height, number of leaves, dry weight, soil pH, organic C, N, P, K, and N absorption. Results of the study showed that bokasi fertilizer 1 at a dose of 167 g polybag-1 gave the highest cajuput seedlings, and bokashi fertilizers 3 with a dose of 167 g polybag-1 gave the highest  number of cajuput seedling leaves.

Abstract

The main problem in the Karangduren sugarcane soil is the low availability of soil-P that leads to the low of cane production. The objectives of this study was to determine the effects of filter-cake, sugarcane boiler ash and compost on availability of soil-P and growth of sugarcane at Kebon Agung Sugar Mill in Karangduren village of Malang. The treatments tested were control (P0), sugarcane boiler-ash 60 t ha-1 (P1), compost 3 t ha-1 (P2), filter-cake 60 t ha-1 (P3), sugarcane boiler ash 30 t ha-1 + filter cake 30 t ha-1 (P4), sugarcane boiler ash 15 t ha-1 + filter-cake 45 t ha-1 (P5), and sugarcane boiler ash 30 t ha-1 + filter-cake 30 t ha-1 + bio-fertilizers 80 L ha-1 (P6). Results of the study showed that application of sugarcane boiler ash, filter cake and compost improved chemical characteristics of the soil studied and increased growth of sugarcane up to 4 MAP (months after planting). The best treatment in improving soil chemical characteristics and growth of sugarcane was application of sugarcane boiler ash 60 t ha-1 (P1). Application of sugarcane boiler ash 60 t ha-1 was able to increase soil pH by 6.12%, increasing the content of soil C-Organic by 46.03 % and soil-P availability by 328.39 % compared to soil before treatment. Application of sugarcane boiler ash 60 t ha-1 (P1) was also able to improve growth of sugarcane measured by the cane height, cane length, number of shoots, number of leaves, content of chlorophyll, cane dry weight and P-uptake of sugarcane.

Abstract

Application of organic matter is done as one of the basic activities of soil fertility management in sugarcane plantation. Application of organic matter at the planting site can be done based on the status of soil organic matter from map of the status of soil organic matter. Differences in the status of soil organic matter can be caused by differences of soil management, such as compost, liquid organic fertilizer and trashes application. As a basic activity of soil fertility management, organic matter application has a significant influence in the availability of soil-N, C/N ratio and soil pH. Content of soil organic matter in the sugarcane land are ranged from 0.9% to 3.5%, and distributed from “very-low” to “moderate” status.

Abstract

To establish suitable lands for sugar cane plantation,  evaluation and suitability of existing land can be made using integration between Geographic Information System (GIS) and Land Suitability Assessment System (SPKL). This study was aimed to obtain the level of land suitability class in Garut regency, and arrange the direction of sugar cane plant development in Garut regency, West Java. The research activity was conducted in Geospatial Information and System Analysis Laboratory at Agricultural Land Resources Center Bogor and Garut Regency. All activities were carried out from April to August 2017. The research stages started from the preparation stage, data processing, field verification, determination of the land management and sugar cane cultivation development. Observation points were determined using purposive sample method based on the difference of limiting factors and accessibility. Results of SPKL program running and data merging on ArcGIS software showed that on sugar cane field in Garut Regency there are three results of land suitability evaluation according to moderately suitable (S2) marginally suitable (S3) and not suitable (N). The results of land suitability evaluation on sugar cane showed that the main limiting factor of growth were five types, i.e. drainage class (rc1), base  saturation (nr2), slope (eh1), average temperature (tc1), and soil depth (rc4). A total number of moderately suitable (S2) land for sugar cane in Garut is 131.558 ha, 514.633 ha for marginally suitable (S3) and 318.387 ha for not suitable (N).

Abstract

In Selorejo village, one of the centers of citrus-production in Indonesia, there are differences fruit productivity in between citrus-farmers. The high productivity citrus gardens produced 55.6 t ha-1 year-1 and in the garden with low productivity produced 26,7 t ha-1 year-1. Differences in these fruit productivity are due to differences in application of fertilizer and crop-management systems. This research was conducted by field survey and laboratory analysis. There were two observation sites as samples of the high productivity gardens (KPT) and the low productivity gardens (KPR). Soil samples taken from each garden were analyzed of soil-CEC, soil C-organic, Base saturation, soil texture, and pH to evaluate suitability of soil at each locations. Results showed that nutrient was not a dominant factor affecting fruit productivity. It is known that almost all soil characteristics suggest the same criteria.The difference was in the C-organic value that was at KPT only 0.78, whereas in KPR C-organic value reached 1,0. The actual land suitability of KPT is S3ehnr and of KPR is S3eh. Based on results of this study can be concluded that soil C-organic, land-slope and crop-management determined productivity of citrus garden.

Abstract

Organic matter in the soil can provide nutrients to plants. The objectives of this study were to analyze soil characteristics after incubation using biochar at various doses, and to calculate the reduction of methane gas emissions from incubated soils. The treatments were (1) soil control (T0); (2) 4 t ha-1 biochar + soil (T1); (3) 8 t ha-1 biochar + soil (T2); (4) 12 t ha-1 biochar + soil (T3); (5) 16 t ha-1 biochar + soil (T4); (6) 20 t ha-1 biochar + soil (T5). The soil of each treatment was incubated for 30, 60, and 90 days. Observations were made on pH, exchangeable cations (Ca, Mg, K, Na) and cation exchange capacity (CEC). Methane gas emissions were measured at 30, 60, and 90 days after planting. The percentage increase in incubation soil pH for 30 days was 3.13-48.71%, 60 days was 3.06-21.26%, and 90 days was 0.41-28.26%. CEC also increased from 28.83 to 37.46 me 100 g-1 (29.95%) at 30 days, 27.63-36.16 me 100 g-1 (30.86%) at 60 days, and 26.07-35.01 me 100 g-1 (34.28%) at 90 days. Exchangeable Ca, and Mg was not significantly different for all biochar doses and incubation times. The reduction in methane gas emissions ranged from 9.57-18.08% (30 days); 33.13-35.23% (60 days); and 46.08-73.25% (90 days).

Abstract

The national production of garlic that is currently under fluctuations and could not fullfill demand for garlic that led Governments to perform the import. Land extensification for garlic in East Java, Pujon district, Malang is expected to be the solution to increase production. However, restricted by the limitations of the information of land characteristics that remains unclear, it takes effort to find out the land characteristics for garlic in the subdistrict of Pujon. Research was carried out for gathering information of land characteristic and to analyze relationships between land characteristics and garlic production. This study was carried out using survey method include groundcheck, minipit observation, soil sampling, and interviews to the farmers. Then, post survey analysis activities include laboratory analysis, soil classification, and statistical data analysis to test the correlation between land characteristics with garlic production. Results of the research showed that land of garlic in Pujon District has Inceptisols and Alfisols. The land characteristics in Pujon district has difference, among others, land elevation are 861–1.213 mdpl, slope of land are 3–36%, soil texture are “loam” to “clay “, soil aggregate are “very-stable”, soil pH ranging from very acid to semi acid, soil CEC are “moderate” to “very-high”, and the base saturation are “low” to “very-high”. The relationship between land characteristics to crop production, proved by correlation between variable such as elevation (r =-0.559), CEC (r =-0.515), base saturation (r = 0.561), % sand fraction (r = 0.541), and % clay fraction (r = -0.675). Other factors affecting garlic production are varieties of garlics and soil tillage, these correlation are not significant.

Abstract

One of the essential soil resources for garlic cultivation is the soil available water content. The purposes of this study  were to create pF curves in the garlic areas, to find out the available soil water content, and to find out the impact of pore distribution on available soil water in garlic areas in Pujon, Malang. Parameters observed were soil texture, soil bulk density, soil specific gravity, soil available water content, pF curve, distribution of soil pores and soil porosity. Results of the study showed that there was a specific pF curve at each observation point. Status distribution of soil available water content in garlic areas was high, medium and low. Furthermore, the pore distribution which includes macropores and mesopores was a factor that influenced the soil available water content. The result of this study expected to be able to give beneficial information that can be used as a reference in land management. Also, it is expected that the land management in the garlic areas, Pujon sub-district, Malang will take land mapping unit 2 as the land management to improve the garlic production.

Abstract

Pujon District is one of garlic centers for increasing garlic production in Malang. One of the causes of low garlic production is the low soil fertility. The status of soil fertility in garlic areas is influenced by availability of soil N. This study was conducted in Pujon District, Malang. The observation points were spread over five villages of garlic centers, i.e. Pandesari, Pujon Lor, Sukomulyo, Bendosari, and Madiredo. Correlation analysis was conducted for data of soil chemical and physical properties obtained from laboratory analysis. The garlic production was used as a dependent variable, while the soil N-total, C-organic, pH (H2O), pH (KCl), bulk density, and soil porosity, were used as the independent variables. Results showed that status of soil N the garlic center of Pujon District was in the low to medium category. Content of N in the topsoil (0-30cm) of the five land mapping units was medium, while that in the subsoil (30-60cm) of the five land mapping units ranged from low to medium. The large or small N content in the soil did not significantly correlated to organic C, pH (H2O and KCl), bulk density and soil porosity. There was a significant correlation between garlic production and the C/N ratio. However, the significant correlation was only found in the lower layer (30-60cm) with the r=0.82**.
