The Ecological Perspective of Landslides at Soils with High Clay Content in the Middle Bogowonto Watershed, Central Java, Indonesia

The clay layers at hilly regions in the study area were very thick. The presence of very thick clay caused several difficulties in terms of environmental management, particularly in reducing georisk due to landslide. However, initial observations proved that areas of active landslides had better vegetation cover. The objective of this study was to find out ecological roles of landslides in livelihood in the Middle Bogowonto Watershed. The ecological roles of landslide were examined through field empirical evidences. Texture, bulk density, permeability, structure, and index plasticity were conducted for analyses of soil physical properties. Stepwise interpretation was made using 1 : 100,000–1 : 25,000 Indonesian topographic maps and remote sensing images of 30 m–<10 m spatial resolution. The results showed that landslides formed three landform zones: residual, erosional, and depositional zones. The area that did not slid, the residual zone, had massive soil structure and very hard consistency. Crops cultivated in this zone did not grow well. In the areas of active landslide, the environmental conditions seemed to be more favorable for living creatures. The landslides resulted in depositional zones with gentle slopes (4° to 15°), higher water availability, and easier soil management. The landslides also acted as the rearrangement process of landforms for better living environment.

Ten representative pedons from the Bulia micro watershed of Gorontalo Province, Indonesia, were characterized and classified to determine its land quality (LQ) class. Angular blocky, sticky, plastic consistencies and a hard consistency prevailed in the soil structure. In the alluvial plains the soil texture is dominated by the clay fraction, while in the hills and volcanic mountains the sand fraction is dominated. The soils in the Bulia micro watershed also have acid to neutral reaction, with the range of very low to high OC (organic carbon) levels, the reserve of exchangeable bases was dominated by Ca2+ in two series patterns, namely: Ca2+ > Mg+ > Na+ > K+ and Ca2+ > Na+ > Mg+ > K+, cation exchange capacity (CEC) ranged from low to very high, and the base saturation varied from moderate to very high. The alluvial plain is represented by Inceptisol in P1 and Typic Humustepts (P7), also by Oxic Humustepts (P3), then Mollisol on P4 (Typic Argiudolls) and Typic Haplustolls (P6), Alfisol on P5 (Typic Paleustalfs). Entisol on P2 (Typic Ustipsamments) was found in volcanic mountains and P9 (Typic Paleustolls) P8 (Ultic Paleustalfs), P10 (Inceptic Haplustalfs) are typical of volcanic hills. On the alluvial plains the land was categorized as the LQ class II, III and IV, the volcanic mountains were the LQ class IV, while the land on the volcanic hills was categorized as the LQ class VI. River bank erosion on the land river terraces can be held by the manufacture of gabions, talud, cliff reinforcement plants and terraces. The soil temperatures and high clay content can be regulated by mulching and organic materials.

Development Goals

Sustainable development as a development process giving environmental aspect needs attention. As an effort to reach sustainable development, the United Nations envisioned comprehensive vision to reach the better world in 2030 through Sustainable Development Goals (SDGs). Gender equality and land ecosystem are considered two of seventeen objectives of SDGs, where land ecosystem covers forest management to actualize sustainable forest. Since 2000 the Indonesian government echoed gender mainstreaming strategy through gender-perspective integration in various fields of development. Even, the Forest Minister in 2011 and 2017 issued regulation on gender mainstreaming in living environment and forestry. This research aims at studying gender responsiveness of policy on forest management. It is a qualitative descriptive research conducted in Central Java Province since the location constitutes a preserved forest with wide critical land. Documentation studies and in-depth interview were employed as data collecting technique. The research result reveals that forest management in the national level is gender-responsive, namely it has considered the different needs between men and women. However, policy in the local level is still neutral gender. Women have access towards forest sources but they don’t have control on it. The social norms about gender role contributed to gender relation in forest management.

Pore Size Distributions

<p>The soil structure near the surface of agricultural soils changes with seasons mainly by land management together with climatic and biological factors. Quantitative analysis of post-tillage changes in soil structure and related hydraulic properties are necessary for evaluating and improving models of soil hydrological and transport processes. The objectives of this study were to quantify changes in soil seedbed structure induced by rainfall and drainage and to estimate the e&#64256;ects of soil texture and SOC on these changes. We collected samples from the harrowed layer of twenty-six &#64257;ne to coarse textured Swedish mineral soils. Air-dried soil was placed in cylinders (5 cm high, diameter 5 cm) and exposed to simulated rainfall (5 mm h<sup>&#8722;1</sup> for 4 h) and drainage (-50 cm pressure potential) cycles in the laboratory. We used X-ray tomography to quantify changes in pore networks in a thin surface layer and in the whole cylinder. Infiltration rates at -5 cm pressure potential were measured using a mini disc tension infiltrometer on replicate air-dried samples and on the samples included in the consolidation experiments at the final state. Total imaged specific pore volumes generally decreased from initial to final state and pore size distributions were shifted towards larger proportions of below image resolution pores (< 80 &#956;m). There was a strong positive correlation between clay content and changes in the specific volume of pores<80 &#956;m. Soils with high clay content and soil organic carbon (SOC) content often have strong aggregates that resist change. Nevertheless, both clay and SOC contents were negatively correlated with the changes in specific imaged pore volume. These results highlight the importance of swelling, which is largely controlled by clay content, for seedbed consolidation. In line with previous studies, when excluding coarse textured soil, the changes in surface porosity were negatively correlated with silt content. Changes in infiltration capacity were not significantly correlated to any basic soil properties. Our results suggest that shrinking-swelling should be a central part in any model for seedbed consolidation.</p>

The Times

Kebonan Village, Semarang Regency, Central Java is the region with the highest number of diarrhea cases. Based on the profile of Puskesmas Regency/City Semarang in 2014, there were 84 findings of diarrhea cases. The initial observation revealed that living environment in Kebonan village was not hygiene. Most of the times, the ditch loaded by garbage, the food often surrounded by flies, people often do not wash their hands after completing their daily activities, and there are houses that still have no latrines. These behaviors were not in accordance with the Clean and Healthy Behavior, thus estimated as the main cause of high cases of diarrhea in Kebonan. This situation was in opposition with Government socialization to local residents about Clean and Healthy Behavior (Perilaku Hidup Bersih dan Sehat/PHBS). Therefore, the problem identified in this research is the failure of government programs through the Department of Health in disseminating the importance of PHBs which resulting in the high number of diarrhea. The aim of this study is to describe the perception of citizens about the PHBS in Kebonan Village, Semarang. This study used the qualitative method with the descriptive design. Researcher employs primary and secondary data. Primary data collected through in-depth interviews with residents of Kebonan, while secondary data was gathered through observations. Data validity was further tested through member-checking method. The research concludes that the perception of Kebonan residents on PHBs are divided into three aspects: realizing the physical and environmental cleanliness, who is responsible for realizing PHBs, and constraints in realizing PHBS. Citizen roles to keep the environment clean, manage domestic waste, use a proper toilet, washing hand and bathing, and keeping female organ hygiene are essential in creating a good and clean living environment.

The transformation of natural ecosystems into agricultural environments modifies the soil structure and it may result in its compaction. Therefore, the objective of this work was to determine the optimum moisture for soil compaction (wot) and maximum soil compaction density (Dsmax) in different soil classes in western Bahia State. The samples were collected in five sites covering different soil classes: Orthic Quartzarenic Neosol (RQ), Orthic Ebanic Vertisol (VEo), Haplic Cambisol (CX) and two Red-Yellow Latosol, one already cropped (LVA) and another with native forest (LVA1). Wot and Dsmax were determined according to ABNT NBR 7182 (1986) standards. Data were submitted to a regression analysis and also to the analysis of the principal components (PCA). Wot presented a decreasing order: VEo> LVA> LVA1> CX> RQo, ranging between 8.20 and 15.00% and Dsmax showed the following order RQo> LVA> LVA1> CX> VE, ranging between 1.34 and 1,92 Mg.m-3. The wot was directly proportional to the clay content and the organic carbon and inversely proportional to the soil sand content. For Dsmax, the influence of the clay was inversely proportional whereas in wot, this variable promoted the growth.
