Soil creep occurred in Balekambang, Cirawamekar, Cipatat, West Bandung Regency, West Java. This area is karst hill consist of limestone with interbedded sediment in the valley. The limestone is interfingered with clay, marl and quartz sandstones. The clay and marl acting as the slipping plane with a steep dip of around 50o to 69o to the northwest. The direction of the slope movement approximately follows the direction of the bedding plane therefore the bedding plane control the soil creep. This landslide was triggered by rainfall which saturated the soil layer and environmental changes in the surrounding area.

Abstract. Iskandar BS, Iskandar J, Partasasmita R. 2019. Hobby and business on trading birds: Case study in bird market of Sukahaji, Bandung, West Java and Splendid, Malang, East Java (Indonesia). Biodiversitas 20: 1316-1332. Bird species have various ecological and socio-economic-cultural functions for the human being. Ecologically, birds have beneficial functions in the ecosystem, such as helping plant pollinators, spreading plant seeds, participating in controlling agricultural pests, and monitoring environmental changes. Meanwhile, bird functions for the social-economic and culture of the community among them are known as sources of protein food, mystical functions, sources of material stories, sources of inspiration to make songs, craft materials, the source of gene pool, and become pets and trade animals. With the rise of the urban population hobby of raising birds and also the development of various bird contest activities in the urban, causing of the bird trade is very widespread in urban areas, such as in bird markets. In some cities in Indonesia, various bird markets have been popularly known for a long time. This study aimed to elucidate species diversity, folk classification, bird populations, bird prices, constraints to bird trade, and the positive and negative effects of bird trade in the urban bird market. The research method used a mixture of qualitative and quantitative methods with the ethnoecological approach. The results of this study showed that from a survey of 60 bird traders in the bird market of Sukahaji, Bandung, and Splendid, Malang, a total of 160 bird species, representing 38 families were documented. Among them, 10 species representing 7 families recorded as protected bird by law in Indonesia, based on recent government regulation of the Minister of Environment and Forestry of Republic of Indonesian No.106/MENLHK/SETJEN/KUM.1/12/2018. A total of 2,950 individuals were recorded in Sukahaji; while in Splendid were recorded 3,558 individuals. Prices of birds that are traded varied greatly depending on the species and characteristics of birds. It has been revealed that bird trade in the bird market has been various economic benefits for many people. However, due to the bird trade in bird markets in the city which has not been properly managed, the sustainability system of the bird trade in the city is very alarming caused of many factors, including decreasing of bird population over time in rural ecosystem as main supply of urban bird trading in the bird markets. Therefore, bird trading in the bird markets must be properly managed based on the sustainable development program concept, namely pro-economic, pro-social, and pro-environment.

 West Java Province has the largest population amongst others in Java, and therefore land conversion rate in the region is increasing. Approximately 40% of forest areas in West Java has been converted between 1990–2015. As a consequence, the number of bi­odiversity in the region is decreasing, including amphibians and rep­tiles. These groups play an important role in the food chain of an ecosystem, and are very sensitive to environmental changes. How­ever, comprehensive research on amphibian and reptile species in West Java is suboptimal. Visual Encounter Survey has performed in seven districts in West Java for one month and has recorded 26 amphibian species and 27 reptile species. These species were in­cluding Javan endemic species (for example: Fejervarya iskandari, Huia masonii, Limnonectes microdiscus, Megophrys montana, and Microhyla achatina), introduced species (Calotes versicolor), and species with a new distribution record (Leptophryne borbonica and Kalophrynus minusculus). In addition, cryptic species (Genus Lep­tophryne and Cyrtodactylus), which are interesting for further stud­ies, were observed. This study has demonstrated that the potential of a comprehensive study of amphibian and reptile species in West Java is great. Apart from this, conserving the biodiversity in the region also challenging due to the high rate in land conversion

Geological Analysis

Mount Geger Pulus in Cililin District, West Java shows a cone geomorphology composed of an Andesitic intrusion in which part of the slope is covered by volcanic rock. Small scale landslides have occurred several times indicating that the surrounding area is at risk of landslides. The slope segment of Legok Emo of this mount has a steep to very steep slope, covered by secondary and mixed forests. Settlement lies around the bottom of this slope. The results of geoelectrical measurements and geological analysis of this slope segment indicate that the slope has a potential to landslide that is controlled by tuff acting as a slip plane and can be triggered by rainfall. The layer that has the potential to landsliding are weathered volcanic breccias with a thickness of about 3 meters with a maximum of 5 meters that is overlying tuff which is relatively impermeable.

Abstract. The site at the southern shore of Krakower See shows the Quaternary geology of the surrounding area. The local Quaternary sequence comprises a thickness of 50–100 m of Quaternary deposits while the surface morphology is dominated by the ice marginal position of the Pomeranian moraine, which passes through the area. The bathymetry of the lake basin of Krakower See indicates a predominant genesis by glaciofluvial erosion in combination with glacial exaration. Past research in this area has focussed on the reconstruction of Pleniglacial to Holocene environmental changes, including lake-level fluctuations, aeolian dynamics, and pedological processes and their modification by anthropogenic land use.

Abstract. Ekasari I, Sadono R, Marsono D, Witono JR. 2021. Species composition and richness of viable seed bank after fire events in Mount Ciremai National Park and Kuningan Botanic Gardens, West Java, Indonesia. Biodiversitas 22: 3437-3447. Forest fire is an environmental disaster that can decline ecosystem function and restoration efforts must be considered to restore forest ecosystems after fire events. Natural regeneration using existing soil seed banks is a promising approach in restoration due to its advantage in terms of minimizing cost. This study aimed to examine the species composition and richness of germinable seed banks in several post-fire sites in Mount Ciremai National Park (MNCP) and Kuningan Botanic Gardens (KGB), West Java, Indonesia. One hundred fifty-eight soil samples were collected from the study sites representing fire events (i.e., four post-fire sites and one non-fire site), and soil depths (i.e., upper, middle, and lower). The collection of soil samples and identification of seedlings emergence were conducted from September 2019 to February 2020. Data were analyzed using ANOVA and correspondence analysis using SPSS Version 22. In total, 4626 emergence seedlings were recorded, belonging to 158 species and 58 families in which 41 families in the upper soil layer, 35 families in the middle soil layer, and 33 families in the lower soil layer. The results showed that Poaceae, Asteraceae, and Euphorbiaceae as the most dominant families. The upper soil layer of post-fire site 2018 had the highest species richness (R=11.98), while the lower soil layer of post-fire site 2012 had the lowest species richness (R=2.64). Our findings suggest that when carrying out restoration activities in post-fire areas, it is preferable to use native species that do not compete with species persisted in soil seed banks.

The Bandarudara Internasional Jawa Barat (BIJB) and Kertajati Aerocity are under construction and expected to be a center of economic activity supported by potential of natural resources and agriculture. They later will act as a driver of economic growth in West Java, especially for surrounding area such as Kertajati, Jatitujuh and Ligung Sub-districts. As an affect of the the development of BIJB and Kertajati Aerocity, the water demand of surrounding area will increase. Therefore an analysis of water demand and availability is needed. This research supports by analyzing the water balance, water demand, and also water allocation using WEAP (Water Evaluation and Planing) software tool. Water balance of Cimanuk-Tomo, Cimanuk-Monjot, and Cilutung-Dam Kamun river are analyzed, water demand of the three sub-districts are also projected and become the inputs of the water allocation model. The result of WEAP model simulation shows that the Cimanuk River can meet the water demand of the three sub-districts until 2040.

Abstract. Mutaqin AZ, Kurniadie D, Iskandar J, Nurzaman M, Partasasmita R. 2020. Ethnobotany of suweg (Amorphophallus paeoniifolius): Folk classification, habitat, and traditional conservation in Cisoka Village, Majalengka District, Cimanuk Watershed Region, Indonesia. Biodiversitas 21: 546-555. Amorphophallus paeoniifolius (Dennst.) Nicolson or suweg is commonly called in Sunadese of West Java as suweg that is a species of tuber growing in many regions of the world, including in the Cimanuk Watershed, West Java Province, Indonesia. A. paeoniifolius usually grows in rural areas of West Java in some agroecosystem types, including the homegarden, garden, and mixed garden system. This plant species, in contrast to other tuber species, such as taro, has not been intensively cultivated by rural community in West Java. Even though A. paeoniifolius has not been intensively cultivated, this plant species in the future have the potential to be used for various purposes for human being. Because A. paeoniifolius, one of plant tubers, has a high resistance to unpredictable environmental changes, such as climate change, pest disruption, and easy to maintain. This study aimed to elucidate the traditional ecological knowledge (TEK) of rural people of Cisoka Village, Cikijing Sub-district, Majalengka District of Cimanuk Watershed, West Java on folk classification, habitat, and traditional conservation of A. paeoniifolius. The method used in this study was qualitative. Field data collection was undertaken by observation and semi-structured interviews or deep interviews with competent informants. The results of study showed that the rural population of Cisoka Village, Majalengka District, has recognized two kinds of Amorphophallus. Firstly, Amorphophallus is a commonly consumed that is called suweg which has scientific name as Amorphophallus paeoniifolius (Dennst.) Nicolson. Secondly, Amorphophallus is recognized as not commonly consumed which is called 'iles-iles' (Amorphophallus variabilis Blume). Both species can be traditionally classified based on morphology (tubers, leaf blade and petioles, and flowers), habitat, utilization, cultivation, and suitability of growing places. Specifically, A. paeoniifolius, grows in various conditions, growing at non-cultivated lands, such as forests and cultivated land, such as homegarden, garden, mixed-garden, and rice fields, or pond edges, but predominantly grows in homegardens and gardens. Some of these lands are hieum or shaded areas and negrak or open areas. A. paeoniifolius starts to grow and develop at the beginning of the rainy season until approaching the dry season, which is characterized by yellowing and falling of petiole. Conservation of A. paeoniifolius has been based on tradition is carried out by the rural community through storage/ preparation of seeds, which does not destroy A. paeoniifolius that grows in several types of agroecosystems, and is managed semi-intensively in several types of agroecosystems such as homegardens and gardens.
