Abstract

Faktor kehilangan/berkurangnya habitat, dan fragmentasi habitat dapat memberikan dampak buruk terhadap kukang Jawa (Nycticebus javanicus), satwa primata nokturnal yang tergolong dalam kategori Critically Endangered. Kukang Jawa yang hidup di hutan yang terfragmentasi merasakan dampak negatif dari faktor- faktor tersebut dan hal tersebut juga dapat memengaruhi okupansi dalam sebuah kawasan. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi okupansi habitat oleh kukang Jawa di hutan dataran rendah yang terfragmentasi di Kemuning, Temanggung, Jawa Tengah, Indonesia. Untuk mem­perkirakan proporsi penggunaan wilayah, probabilitas detek­si (detection probability) dan faktor – faktor yang berpengaruh terhadap okupansi habitat oleh kukang Jawa, kami menggunakan occupancy model of a single-season. Sebanyak 5 kali ulangan survei malam pada tahun 2017 digunakan sebagai data pokok di dalam model okupansi. Metode pengambilan data lingkungan dan data anthropogenic menggunakan observasi lapangan dan interview dengan masyarakat lokal. Kami membagi lokasi penelitian menjadi 141 grid dengan ukuran 200 m x 200 m (4 ha) sebagai acuan dalam survei malam dengan jalur. Data kovariat lingkungan yang diukur adalah jarak dari jalan, jarak dari tepi hutan, jarak dari pemukiman, jarak dari sumber air, ketinggian tempat, dan kemiringan lahan. Hasil penelitian menunjukan bahwa kukang Jawa menghuni habitat sekitar 23,2% dari keseluruhan areal di hutan Kemuning. Jarak dari jalan dan jarak dari sumber air (sungai) berkorelasi positif terhadap tingkat hunian, sedang jarak dari pemukiman berkorelasi negatif terhadap tingkat hunian dari kukang Jawa. Data dan informasi kuantitatif yang dihasilkan dari penelitian ini penting untuk mengetahui kebutuhan sumber daya jangka panjang populasi kukang Jawa khususnya di hutan Kemuning. Selanjutnya diharapkan pemerintah Indonesia atau stakeholder terkait dapat melakukan upaya konservasi dan rencana strategi pengelolaan spesies kukang Jawa dengan baik khususnya di hutan dataran rendah yang terfragmentasi.Occupancy of Javan Slow Loris (Nyticebus javanicus E. Geoffroy 1812) in Kemuning Tropical Low Land Forest, Bejen, Temanggung, Central Java Abstract Habitat loss and landscape fragmentation have a negative impact on the Javan slow loris (Nycticebus javanicus), a Critically Endangered nocturnal primate species. Slow lorises in remaining forest fragments might be suffered and affect their occupancy behavior. We aim to investigate the determinant factors for the probability of habitat occupancy by the javan slow loris in Kemuning forest fragment of Temanggung District, Central Java. To estimate the site occupancy rate, detection probability, and the determinant factor of site use by Nycticebus javanicus, we employed the occupancy model of a single-season using night surveys. Five repeated night surveys in 2017 were used as the main basis data for the occupancy model. We used direct observation and interview with locals to collect data on environmental and anthropogenic features. We divided the study area into 141 grids with 200 m x 200 m (4 ha) each which were the basis for the night survey following existing walking paths. The influence of six covariates was assessed to determine of site use by Nycticebus javanicus: distance to road, distance to forest edge, distance to the settlement, distance to water source, altitude, and elevation. The result shows that the probability of site use occupied by Nycticebus javanicus was 23.2% of the total area. Distance to roads and distance to water source have a positive correlation with the probability of site use, whereas the influence of distance to settlements has a negative correlation with the site use of the species. Such quantitative data and information gained in this research are important to know for the long term resource needs of the Nycticebus javanicus, especially in the Kemuning forest. Therefore, the Indonesian Government or related stakeholders can formulate the detail conservation plans of the species, especially in the lowland fragmented tropical forest.

Abstract

Protected areas play important roles for protecting many endangered species in Indonesia. However, very limited information regarding roles of protected areas and non-protected areas for supporting the habitat of less-concerned carnivores in Java, leopard cat (Prionailurus bengalensis javanensis). We aim to assess the relative roles of non-protected areas for the habitat of this cat on the highly fragmented and populated island of Java. We develop species distribution modelling, using Maxent by integrating various sources of presence data of this species and environmental data. Our finding confirms that leopard cat can life in various habitat types but mainly patchy forest areas. While most of the protected areas are suitable for the habitat of this smallest cat on Java, the non-protected areas provide much larger areas for its habitat (66.8 %). Our findings highlighted the importance of maintaining connectivity among habitat patches in non-protected areas, habitat protection using current government policy on high conservation value forest and essential ecosystems areas. Pentingnya Kawasan Non Lindung sebagai Habitat Kucing Hutan (Prionailurus bengalensis javanensis Desmarest, 1816) di Jawa, IndonesiaIntisariKawasan lindung memainkan peran penting dalam melindungi banyak spesies yang terancam punah di Indonesia. Walaupun demikian, informasi mengenai peran kawasan lindung dan kawasan non lindung untuk mendukung habitat karnivora yang kurang mendapat perhatian di Jawa, kucing hutan (Prionailurus bengalensis javanensis), sangat terbatas. Penelitian ini bertujuan untuk menilai peran kawasan non lindung sebagai habitat kucing hutan di Pulau Jawa, pulau yang sangat terfragmentasi dan padat penduduk. Kami mengembangkan pemodelan distribusi spesies, menggunakan Maxent dengan mengintegrasikan berbagai sumber data kehadiran spesies kucing hutan dan data lingkungan. Temuan kami menegaskan bahwa kucing hutan dapat hidup di berbagai jenis habitat tetapi habitat utamanya adalah kawasan hutan yang agak terbuka. Meskipun sebagian besar kawasan lindung sesuai untuk habitat kucing terkecil di Jawa ini, kawasan non lindung justru menyediakan area yang jauh lebih besar untuk habitat kucing hutan (66,8 %). Temuan kami juga menyoroti pentingnya menjaga konektivitas antar habitat di kawasan non lindung dan perlindungan habitat dengan menggunakan kebijakan pemerintah saat ini tentang hutan Bernilai Konservasi Tinggi dan Kawasan Ekosistem Esensial.

Abstract

Since it was first held in 2012 the Gandrung Sewu Festival has become a favorite in the Banyuwangi Festival event. The popularity of Gandrung Sewu appears not only because this show is aesthetically appealing, but also it holds the stories and desires of the people Banyuwangi. In addition to describing the implementation of the Gandrung Sewu performance which is part of the Banyuwangi Festival event, this paper also aims to reveal the history of the heroism of the Blambangan people which became the background for the emergence of Gandrung and later became an art performance called the Gandrung Sewu Festival. This paper is based on field note from observations of the Gandrung Sewu Festival and in-depth interviews with resource persons who have competence and relevance. The result of the study show that the Gandrung Sewu not only an art performance created from Gandrung which has become one of the icons of Banyuwangi’s arts and culture, but also an image of the herois of the Blambangan people in a war against foreign domination in the past, the heroism of the Bayu war unites returned the people of the Blambangan who were scattered in a new spirit which was marked by the birth of Banyuwangi. The heroism of the Blambangan people, which the people of Banyuwangi continues to love, continues to be eroded in to a variety of purely aesthetic artistic creativity in order to serve the growing demand for the tourism markes, especially in the era of Regent Abdullah Azwar Anas’leadership in 2010-2020.
