Abstract

The main effects of human activities on the environment result in land use and land cover changes. Land over exploitation and development activities in West Kalimantan of Indonesia necessitated the focus of this research which aims to analyzing and predicting land use changes in West Kalimantan. The results of such a study assist researchers, planners and policy makers to formulate suitable land use policies in the future in order to balance economic development and natural resource conservation. Moreover, it makes Indonesia shift from middle incomes to become a developed country in 2030.  Methodology employs field observation, key informant interviews, focus group discussions and system dynamics modeling. The field observation covered communities in several locations in the study site to identify pattern of land use. The system dynamics was applied to analyze the land use change system and estimate the extents of land cover change in the future. The study showed several outcomes: (i) The main leverage factors in the land use change system in West Kalimantan were the desire to reach the expected economic growth and the increased per capita consumption of edible oil globally; (ii) In the business as usual modeling, the increasing global demand  for edible oil will lead to significant increment of oil palm plantation area, even the total area of plantation could be wider compare to that of the remaining forest area by 2030; (iii) Key interventions that need to be considered in the future is to conduct reforestation (with reforestation rate of at least 0.5% per year) and limited oil palm plantation development to maximum of 50% of developed  area.

Abstract

Pre-release aassessment study of Javan gibbon (Hylobates moloch) in gradually during acclimatization phase in the Mount Malabar Protected Forest, West Java. We studied eleven Javan gibbons in February-March 2014, February-March 2015, March-April 2015, and July-August 2016. The purpose of this study was to assess the readiness of Javan gibbon behavior in acclimatization phase prior to release. Data collection was conducted by focal animal sampling method with 5-minute interval recording time  and ad libitum method. The average time allocation of Javan gibbon activities were the following: feeding 16.82±1,28%; moving 20.01±3.14%; resting 47.64±1.31%; socializing 12.88±2.92%; sexual 0.69±0.54%; and vocalizing 1.96±0.59%. We compared activity allocation data from this study and those from wild Javan gibbons and found similarities as follows: 55.30% at a family of Jowo-Bombom-yani-Yudi, 51.42% at a pair of Moly-Nancy, 44.57% at a pair of Robin-Moni and 62.19% at a family of Mel-Pooh-Asri. Based on readiness assessment of 11 Javan gibbons, 3 were considered almost ready for release, while 8 individuals were considered  ready.

Abstract

Keanekaiagaman primata Indonesia meiupakan suatu kekayaan yang tidak terdapat di negaia lain. Kawasan Indonesia mempunyai primata mulai dari yang berevolusi iendah yaitu Tarsius bancanus sampai yang berevolusi tihggi seperti orangutan (Portgopygmaeus). Beberapa primata ada yang bersifat endemik, seperti lutung meiah di Kalimantan (Davis1962, Medway 1970, Stott & Selsor 1961).Tempat hidup lutung meiah, yaitu pulau Kalimantan, pada dasa waisa sekaiang ini sedang giat dieksploitasi.Eksploitasi diketahui banyak menimbulkan kerugian terhadap penghuninya, misalnya adanya emigrasi dan kepunahan tidak langsung. Beberapa hewan telah menunjukan kelangkaan di daerah yang diekploitasi hutannya.Lutung merah sebagai hewan arboreal mungkin sekali akan terganggu oleh adanya eksploitasi hutan tersebut.Oleh karena kerusakan hutan mungkin akan berpengaruh terhadap tingkah laku lutung, maka penelitian mendasar terhadap hewan ini perlu dilakukan Untuk memulainya dilakukan penelitian awal dalam taraf pengamatan aktivitas, pergerakan dan beberapa segi tingkah laku lutung. Penelitian ini diharapkan dapat membantu cara pelestarian hewan ini.
