Abstract

Abstrak. Meningkatkan kualitas ekologis suatu kota dapat dilakukan dengan membentuk ruang terbuka hijau. Perumusan kebijakan ruang terbuka hijau secara berkelanjutan dipengaruhi oleh berbagai kriteria, di mana indikator-indikator dalam kriteria tersebut saling terkait. Penelitian ini bertujuan untuk mengetahui kebutuhan luas ruang terbuka hijau dalam mewujudkan tata kota berkelanjutan di Kota Bandar Lampung. Indikator dalam menentukan kebutuhan ruang terbuka hijau antara lain adalah jumlah populasi, luas lahan, dan emisi CO2. Berdasarkan populasi pada tahun 2017, kebutuhan ruang terbuka hijau sesuai program pemerintah adalah 2.673 ha, sedangkan luas ruang terbuka hijau hanya ada 2.475 ha sehingga ada perbedaan kekurangan ruang terbuka hijau sebesar 197 ha. Lebih jauh, Kota Bandar Lampung berdasarkan luasnya membutuhkan ruang terbuka hijau seluas 5.916 ha. Tingkat emisi CO2 di Kota Bandar Lampung pada tahun 2017 adalah sebesar 9.118 Gg th-1 sedangkan prediksi total emisi CO2 pada tahun 2024 adalah 133.202 Gg CO2-1 th-1. Sehingga luasan yang ruang terbuka hijau yang dibutuhkan adalah sebesar 156 ha. Angka ini akan meningkat sejalan dengan pertumbuhan penduduk. Untuk itu luas ruang terbuka hijau perlu disesuaikan secara berkala untuk penyerapan emisi CO2 dan keserasian kota.Abstract. Improving the ecological quality of a city can be done by creating green open space. The formulation of a green open space policy for harmonious city is influenced by various interrelated factors. This study aimed to estimate the area of green open space in realizing sustainable green open space in Bandar Lampung City. Indicators in determining the needs of green open space were the population, land area, and CO2 emissions. Based on the population in 2017, the green open space requirement as targeted by the local government was 2,673 ha, while the extent of existing green open space was is only 2,475 ha, hence a need for 197 ha more green open space area. Bandar Lampung City based on its area requires a green open space of 5,916 ha. The level of CO2 emissions in Bandar Lampung City in 2017 was 9,118 Gg/year, while the predicted total CO2 emissions in 2024 is 133.202 Gg/CO2/year and hence the city require additional green open space of 156 ha. This number will increase in line with population growth. For this reason, the area of green open space needs to be adjusted regularly for the absorption of CO2 emissions and the harmony of the city.

Abstract

Hymenoptera is one of the four largest insect order (the other three are Coleoptera, Diptera, and Lepidoptera). There are curerently over 115 000 described Hymenoptera species. It is clear that Hymenoptera is one of the major components of insect biodiversity. However, Hymenoptera biodiversity is affected by ecology, environment, and ecosystem management. In an agricultural areas, the spatial structure, habitat diversity, and habitat composition may vary from cleared landscapes to structurally rich landscape. Thus, it is very likely that such large-scale spatial patterns (landscape effects) may influence local biodiversity and ecological functions. Therefore, the objective of this research were to study diversity and configuration elements of agricultural landscapes at Cianjur Watershed with geographical information sytems (GIS) and its influence on Hymenoptera biodiversity. The structural differences between agricultural landscapes of Nyalindung, Gasol, and Selajambe were characterized by patch analyst with ArcView 3.2 of digital land use data. Results indicated that class of land uses of Cianjur Watershed landscape were housing, mixed gardens, talun and rice, vegetable, and corn fields. Landscape structure influenced the biodiversity of Hymenoptera. Species richness and the species diversity were higher in Nyalindung landscape compare to Gasol and Selajambe landscape. Key words: diversity, Hymenoptera, landscape, watershed, GIS

Abstract

DNA barcoding based on mitochondrial DNA COI gene is very useful in identifying of Indonesian hornbill. We sequenced the DNA barcode of seven hornbill species using the mitochondrial DNA COI gene to explore their genetic variation, identity, distance, and phylogenetic. Thirty-one blood samples from seven hornbill species were isolated and analyzed. Slight variation was observed within the nucleotide of the hornbill species. In contrary, fairly significant difference was shown within the genus and family level. COI gene sequences generated from this study, showed unmatched result with BoLD System database. These seven Indonesian hornbill species were then divided into two groups, namely Group I consisting of Aceros cassidix, Rhyticeros plicatus, R. undulatus, Buceros rhinoceros, and B. bicornis, while Group II occupied by Anthracoceros albirostris and A. malayanus; both groups with genetic distance 5.90%. Overall in-group had 9.40% distances to the hornbill used as the out group. COI sequence gene from these seven hornbill species are novel for identifying Indonesian hornbills. We encourage its use as quick species identification, applied to prevent illegal poaching conservation management.

Abstract

Objective of this study was to provide spatial information of Javan gibbon habitat suitability and distribution in Gunung (Mt.) Salak area for Management Authority of Mt. Halimun-Salak National Park. Informations on Javan gibbon distribution was collected through a number of survey during December 2005–June 2006 in Kawah Ratu (Parakan Salak, Sukabumi), Pondok Wisata Cangkuang (Cidahu, Sukabumi), and Bobojong Village (Bogor). Twenty two groups were identified using direct count and triangle count method from over 47 identified positions. Habitat suitability was formulated based on10 ecogeographical variables (criteria), consisting of forest type (primary forest, secondary forest, low-land forest, and submontane forest), slope (0–15%, 15–45%, >45%), and distance to non-forested land, river/water body, and road/tracks. The result showed that Mt. Salak consisted of 13.20% (17.53 km2), 26.25% (34.86 km2), 19.40% (25.77 km2), 4.16% (5.53 km2), and 20.17% (26.78 km2) of high-suitable, suitable, moderate suitable, less and low suitable level subsequently, and 12.69 km2 or 9.56% was not suitable for Javan gibbon habitat. It was also revealed that that 3 and 9 groups were living in high suitable and suitable habitat respectively; 13 groups in moderate suitable, while for each less and low suitable habitat, 2 Javan gibbon groups lived in.

Abstract

Being established in 2004, Gunung Merbabu National Park (GMNP) is one among several new national parks in Indonesia. Ecotourism activities in this area have not been properly developed by Perum Perhutani (as the past management authority) although the area is very potential to be developed as an ecotourism site for activities such as nature interpretation, apart from camping and hiking which are already carried out. With the change of the area’s status into a national park, the opportunity of ecotourism development is increased as the area is presently managed by a management authority named Gunung Merbabu National Park Office. As a part of ecotourism, nature interpretation is very important in connecting visitors to natural resources, which is one of the urgent services of GMNP. The objective of this research is to develop interpretation planning of various nature tracks in the park, based on the tracks’ resources and users’ demands. The Query Builder tool was employed in the selection of the user-oriented nature interpretation tracks. The synthesis of tracks’ resources and users’ demand resulted in 8 tracks, e.g. Selo–Puncak, Tekelan–Puncak, Selo II, Selo III, Tekelan IV, TWA–Krinjingan Waterfall, TWA–Watu Tadah Waterfal, and TWA–”Dufan”.

Abstract

The concept of hydrological tank model was well described into four compartments (tanks). The first tank (tank A) comprised of one vertical (qA0) and two lateral (qA1 and qA2) water flow components and tank B comprised of one vertical (qB0) and one lateral (qB1) water flow components. Tank C comprised of one vertical (qC0) and one lateral (qC1) water flow components, whereas tank D comprised of one lateral water flow component (qD1). These vertical water flows would also contribute to the depletion of water flow in the related tanks but would replenish tanks in the deeper layers. It was assumed that at all lateral water flow components would finally accumulate in one stream, summing-up of the lateral water flow, much or less, should be equal to the water discharge (Qo) at specified time concerns. Tank A received precipitation (R) and evapo-transpiration (ET) which was its gradient of (R-ET) over time would become the driving force for the changes of water stored in the soil profiles and those water flows leaving the soil layer. Thus tank model could describe th vertical and horizontal water flow within the watershed. The research site was Cisadane Upper Catchment, located at Pasir Buncir Village of Caringin Sub-District within the Regency of Bogor in West Java Province. The elevations ranged 512 –2,235 m above sea level, with a total drainage area of 1,811.5 ha and total length of main stream of 14,340.7 m. The land cover was dominated by forest with a total of 1,044.6 ha (57.67%), upland agriculture with a total of 477.96 ha (26.38%), mixed garden with a total of 92.85 ha(5.13%) and semitechnical irigated rice field with a total of 196.09 ha (10,8%). The soil was classified as hydraquent (96.6%) and distropept (3.4%). Based on the calibration of tank model application in the study area, the resulting coefficient of determination (R2) was 0.72 with model efficiency (NSE)of= 0.75, thus tank model could well illustrate the water flow distribution of Cisadane Upper Catchment. The total water yield was 2.789 mm year-1 from 3,624 mm year-1 of total annual precipitation. The total water yield comprised of a total runoff of 47.39% and 49.23% of sub surface flow and base flow.

Abstract

Although translocation has been used in mitigating human-carnivore conflict for decades, few studies have been conducted on the behavioral ecology of released animals. Such information is necessary in the context of sustainable forest management. In this study we determine the type of land cover used as main habitat and examine the activity pattern of translocated tigers. Between 2008 and 2010 we captured six conflict tigers and translocated them 74-1,350 km from their capture sites in Sumatera. All tigers were fitted with global positioning system (GPS) collars. The collars were set to fix 24-48 location coordinates per day. All translocated tigers showed a preference for a certain habitat type within their new home range, and tended to select the majority of natural land cover type within the landscape as their main habitat, but the availability of natural forest habitat within the landscape remains essensial for their survival. The activity of male translocated tigers differed significantly between the six time intervals of 24 hours, and their most active periods were in the afternoon (14:00-18:00 hours) and in the evening (18:00-22:00 hours). Despite being preliminary, the findings of this study-which was the first such study conducted in Sumatera-highlight the conservation value of tiger translocation and provide valuable information for improving future management of conflict tigers.
