Abstract
One of the impacts of artisanal gold mining (ASGM) activity is lead (Pb) contamination in soil. This research was conducted on the Pb contaminated soil at the ASGM sites in Banyumas and Wonogiri in Central Java and Kulon Progo in Yogyakarta. This research aims to conduct a study of Pb mobility in contaminated soil and laboratory experiment to carry out remediation of Pb contaminated soil using natural zeolite with the batch test. The results showed that the Banyumas soil sample had higher Pb mobility compared to the other two soil samples. The batch test results showed that zeolite application useful to reduce Pb in the contaminated soil samples, where the Banyumas soil sample results in optimum value results due to the highest Pb mobility. The batch test results also showed that pH was a significant factor in the remediation process. This study concluded that the zeolite application reduces the concentration and mobility of Pb in the soil and affect the sorption by plants.

The various type of the agricultural activities in study area has different type of land productivities depends on its land capabilities. Land capability analysis with landform approach become the base in this study to identify the sustainable “land utilization type” (LUT) and the land productivity optimal value in Galur sub- district. Observation, measurement, and interview was done by using the Land Classification and Land use Planning (LCLP) tool. Landforms that has productive value identified in this study are: alluvial plain (IId-3), beach ridge (IIIP-2), and beach (VIIIP). The usage of alluvial plain could be rice-(corn/nuts)-rice or could be replaced with rice-chili-rice. The usage of beach ridge could be the planting of plantation crops such as melon, onion, and chili, and could be the farming of goat and chicken. Land usage type in beach is left naturally because it has land capability type VIII (low capability).

Determinants of rural household food security in Indonesia: the case of protein-based food consumption
Authors: Umaroh R , Pangaribowo E H 
Published: March 2020

Abstract
A large number of households in Indonesia, especially those in rural areas, still depend on the agricultural sector. In order to meet their food needs, including protein-sourced food, rural households both produced and purchased their food consumption. This study aimed to analyze whether the consumption of certain self-produced protein-based food, namely, beans, tofu and tempeh, meat, poultry, fish, and milk, contributes to the food security of rural households in Indonesia. Using data from the fourth- and fifth-wave Indonesian Family Life Surveys in 2007 and 2014, the study applied the Quadratic Almost Ideal Demand System (QUAIDS) model to examine the determinants of protein-based food demand. The results reveal that rural households consume more plant-sourced protein than animal-sourced protein. It is also shown that the socio-demographic characteristic of the household such as household structure, the education and age of the household head affect differently on type of protein-based food consumption. These results suggest that self-produced food can be seen as a strategy for rural households to meet their protein-based food consumption. Self-produced food households also tend to be more food secure than the counterpart households.

Abstract
Geomorphologists have considered the anthropogenic process as one of important factors in landforms studies. Numbers of anthropogenic classification are recently introduced without clearly monitoring the relationship between the classes and map scale. This study was designed to classify the anthropogenic landforms in Bompon catchment at a detailed scale. We employed a descriptive and observational survey using the traverse method at 1:10,000 and 1:2,000 map scale. The former created a path of travel with a width of 100 m and 20 m along the stretch of the catchment area. The observation points were selected based on the human activities encountered along the path and in the representative areas, namely type of intervention, formation process, and area. The anthropogenic landforms were grouped according to the modified classification of Szabó & Dávid. The results indicated that human intervention or land transformation occurring in Bompon catchment fell into the categories of Agrogenic, Urbanogenic, Traffic, and Water Management. Each of the four landforms was visible in 1:2,000 map scale, but only the Agrogenic and Urbanogenic ones were classified on a scale of 1:10,000. Denudation, construction, and association are the dominant process in the formation of anthropogenic landforms in the study area.

Abstract
Karanganyar Regency is one of the most prone area to landslides in Central Java. According to DIBI records, 77 of the 149 types of natural disasters that occurred in this area were landslides during 2008-2018 and the trend tends to increase. In disaster management, the ability of the community to reduce the risk of landslides is reflected in capacity. The objective of this study is to know the farmers understanding on landslide factor, landslide occurrences and impact, and landslide mitigation in Beruk Village, Karanganyar Regency. The data was collected by interview to 109 farmers household, and the analysis was conducted by descriptive analysis. The result shows that the landslide is mostly caused by heavy and long duration of rain, indicator for landslide is ground cracks, and the mitigation mechanism is based on local knowledge of farmers such as managing irrigation system, planting trees, and managing land utilization. In Beruk Village, disaster management process is more to be responsive rather than preventive and the knowledge of farmers on land management play an important role in disaster risk reduction.

Abstract
Landuse change is a serious phenomenon which faced by some of the suburban areas. Sleman Regency is one of regencies that is located in suburban area or outskirts of Special Region of Yogyakarta. The imbalanced between the need or the demand and the availability of land in Special Region of Yogyakarta, trigger a city expansion to the surrounding areas, especially in Sleman Regency. The purpose of this research is to study and to examine the impact of landuse change towards to the paddy productivity in Sleman Regency. The landuse analysis was performed by comparing the RBI map of Sleman Regency in 2007 and the RBI map of Sleman Regency in 2017. The result of the research showed us that during 2007-2017 period, the decreasing areas were fields by 0.93%, shrubs by 0.12%, and rice fields by 47.5%. Landuse that experienced increase in area were buildings by 2.89%, plantations by 12.62%, and settlements by 34.26%. The decreasing area of paddy fields did not significantly reduce the productivity of the rice. Rice production from 2007-2017 period is stable and tends to be increase. That is because the area of harvested land from 2007-2017 has also increase due to the agriculture diverification program in Sleman Regency. This research shows us the projection of paddy productivity until 10 years later from 2017.

Abstract
Dry seasons often lead to drought in Panggang Subsystem, part of the undeveloped Gunungsewu Karst that has minimal water resources in its springs and underground rivers. The local people have relied on karst lakes as the primary water source for various activities, such as bathing and cloth washing. Bembem Doline Pond is located in Giriasih Village, Purwosari District, Gunungkidul Regency and is part of the Panggang Subsystem. Aside from its intensive use, many factors are contributing to its water quality degradation, namely seasons, doline pond characteristics (e.g., water volume), landuse on the watershed, and the pattern of water use. This research intended to identify (1) the characteristics and (2) the water quality of Bembem Doline Pond in the early and mid-rainy season. For the water quality analysis, samples were collected from five points, which were selected by purposive sampling technique. This sampling took into account the location of the water inflow and part of the doline pond where human activities took place in November 2018 and January 2019. The test included three types of water parameters, namely physical (temperature, EC, and TDS), chemical (pH, nitrate, phosphate, detergent, and BOD), and biological (total coliform). The results showed that the water volume of Bembem Doline Pond in the mid of rainy season is 1,467.4 m3. Landuse in the watershed are dominated by plantation (45%) and dry farmland (34%), and some were covered by water bodies (14%), roads (2%), buildings (4%), and settlements (1%). The water quality of the doline pond was found to depend on seasons and human activities on the doline pond considerably. The pollutant levels inclined to be higher in the early than the mid-rainy season. In the former, human activities mostly played a part as pollutant supplier, while in the latter, runoff water from agricultural fields in the watershed contributed the most. According to the Regulation of the Governor of the Special Region of Yogyakarta No. 20 of 2008, the majority of the test parameters exceeded the quality standards for Class II water.
