Abstract

ABSTRAKAnalisis Kondisi Hutan Berdasarkan Tutupan Kanopi Menggunakan Pendekatan RemoteSensing. Pengurangan luasan hutan masih menjadi problem di Indonesia teristimewa untukPulau Jawa dengan kondisi populasi penduduk yang terpandat. Untuk mengetahui seberapajauh perubahan kawasan Gunung Papandayan terhadap fungsi bentang ekologinya makadicoba analisis satelit SPOT 2 tahun 2008 dengan standart koreksi pada level 2A. Prosesingdata satelit dilaksanakan dengan melakukan pengukuran awal meliputi radiometri, geometri,dan koreksi topografi untuk memisahkan bentuk bentang penggunaan berupa hutan dan ataulainnya. Penutupan kanopi dicatat menggunakan foto digital dan dianalisis menggunakanperangkat lunak RGBFisheye. Hasil penelitian dapat ditunjukkan bahwa kawasan Papandayanterdiri dari kawasan hutan terbuka (10-40%), semi tertutup (40-70%) dan tertutup (>70%). Hasilanalisis juga dapat dihitung seluas 16,846 ha. Sebagian hutan merupakan hutan semi terbuka(49,38% atau 8983 ha) yang terdiri dari 3604 tapak sedangkan hutan terbuka terdiri dari 15,07%(2741 ha) dan tersusun 16450 tapak.Kata kunci: Kondisi hutan, tutpan kanopi, photograph, Gunung Papandayan.

Abstract

The contribution of biodiversity to economic development, social and ecological in Indonesia today and thefuture are already being felt very real. Unfortunately, as well as economic development approach to the greeneconomy that appears on the answers rampant deforestation and forest degradation, biodiversity atmospheretoday in Indonesia is under pressure and decrease impact on the species and environmental balance problemsand poverty. Besides the problem of public funding also be other problems. In this case, government role to bevery significant through the Transfer to the Regions. By using the methodology analysis desk study, it can berecommended that General Allocation Fund (DAU) is the main policy priority for funding biodiversity, throughthe addition of indicators of the Fiscal Needs (KbF). Other policy options are DAK mechanism throughimprovement criteria.Keywords: Biodiveristy, General Allocation Fund (DAU), Specific Allocation Fund (DAK), Forestry,Environment

Abstract

Hendra merupakan salah satu penyakit emerging dan zoonosis yang berbahaya, termasuk Genus Henipavirus(Paramyxoviridae). Penyakit ini sangat erat hubungannya dengan Nipah, yang dapat menginfeksi ternak babi danmanusia. Survey serologi dilakukan di dua propinsi, yaitu Kalimantan Barat dan Sulawesi Utara. Hasil menunjukkanbahwa 148 kalong (Pteropus sp.) yang terdiri dari 84 P. vampyrus asal Kalimanatan Barat dan 64 P alecto asalSulawesi Utara telah dikoleksi. Hasil serologis mengindikasikan 22,6% P vampyrus di Kalimantan Barat mempunyaiantibodi terhadap virus Hendra, yang juga merupakan reaksi silang dengan virus Nipah. Di Sulawesi Utara, 25%serum mengandung antibodi terhadap virus Hendra, dimana 7,8% diantaranya hanya mempunyai antibodi terhadapvirus Hendra. Dari data tersebut dapat disimpulkan bahwa antibodi terhadap virus Hendra terdeteksi padaP. alecto di Sulawesi Utara. Hasil ini merupakan laporan pertama tentang infeksi Hendra pada P. alecto di Indonesia.Adanya perbedaan prevalensi tersebut, dapat disebabkan oleh letak geografis atau spesies kalong yang diuji.Kata kunci: P. vampyrus, P. alecto, antibodi, Hendra, Nipah, Serum Netralisasi

Abstract

ABSTRACTSmall mammal community in various habitats at Apuy track and Linggarjati trackof Gunung Ciremai National Park. Distribution of small mammals at Apuy track(west slope) and Linggarjati track (east slope) of Gunung Ciremai National Park arecorrelated with their habitats. Traps, mist nets and observational methods were conductedto record small mammals from seven different habitats. To interpret such patterns, weconducted cluster analysis based on Jaccard index of similarity resulting five distinctgroups. Species diversity for each habitat differs significantly indicating great diversitydifferences between habitats. Common species appear to occupy disturbed area alongthe habitats examined, where as rare species tend to associate with more distinctivehabitat types. The results seem to suggest that forest may still consitute an substantialcomponent for the preservation of small mammals.Key words: ciremai, small mammals, habitat, distribution, zoning.

Abstract

Ease of access, affordability and continuity of katuk production is important to support a variety of supplements industry-katuk based being developed at this time. The problem is the existing clones and its cultivation technique has not been able to fulfil the market needs. Therefore clone assembling was done to produce triploid katuk with larger leaves size. In this paper we put forward the research on the fertilization and pruning time that appropriate to support the leaf production of triploid katuk. The study was carried out at the experimental plot in Botany Division of Research Center for Biology-LIPI. The experimental designs was Nested RCBD Design, the main plot were 2 level of pruning time (P1: 3 Weeks After First Pruning (MSPP) and P2: 5 MSPP). The subplots were fertilization (K: Control, B: Beyonic, B ¼: Beyonic + NPK¼, B ½:  Beyonic+ ½ dose NPK and NPK: NPK without Beyonic). The growth parameters observed were plant height, number of leaves, the leaf size, were done every week until 8 weeks after planting (WAP). The first pruning to harvest shoots were done at 8 WAP, and the next pruning were done according pruning time treatment i.e. P1 and P2. The pruning was done 3 times. The variables observed at pruning time were shoot length, number of leaves, leaf size, the pruned fresh weight and the fresh weight of edible parts. The result indicated that the triploid katuk clones showed a good response to fertilization both growth and leaf production. The biofertilizers can be combined with the use of inorganic fertilizers to increase edible part of pruning harvest production. Keywords: pruning time, bioorganic fertilizer, triploid katuk, pruning harvest production

Abstract

ABSTRACTTrend and Causal Factor of Deforestation in Way Pemerihan, Bukit BarisanSelatan National Park, West Lampung. Deforestation of low land tropical forestis one of the greatest threats to biodiversity in Bukit Barisan Selatan National Park(BBSNP), where this area is the third-largest protected area on Sumatra. Our study is thefirst in BBSNP as integrate between remote sensing and socio-economic survey to demonstratethat the area and rate of forest loss in Way Pemerihan (Cawangaro andSumbersari). The data demonstrated that deforestation activity has been started since1965 in Cawangaro and 1977 in Sumbersari. Forest cover of 1.232ha had already beenlost by deforestation activity, i.e: 579 ha in Cawangaro and 653ha in Sumbersari. Forestloss is increasingly by average rate of 1.2%/year (0.28m2/minute) in the meantime averagerate of regeneration only 0.09%/year. The highest increased of deforestation hasoccurred after politics reformation in 1998. The result of socio-economic survey demonstratedtwo causal factor include internal factor and external factor. Internal factor that islandlessness, price of outside BBSNP land is relatively high and not productive becauseof that low production. External factor of the processes which drives farmer to deforestationis social gap to illegal logging activity, declined of BBSNP forest control and lawenforcement capacity, and boundary conflict between BBSNP with traditional lands.Political reformation forms is the basis for increase external factor.Keywords: Forest loss, satellite imagery, landscape, Illegal logging

Abstract

A total of 2466 fish were sampled from Serayu River in Banjarnegara, Central Java. The aims of study are to assessthe relationships among length weight, growth, condition factors and sex ratio of of the brek fish (Barbonymusballeroides) with fragmented habitat. The study started from June 2012 to May 2013 using survey mehods. Thestudy sites consist of six stations which were into three segments based on the reservoir position, i.e lower segment(St.1-St.2), middle segment (St.3-St.4), and upper segment (St.5-St.6). The results show length weight relationshipwere W= W= 7.10 -7*L3.084 (r2= 0.97) for all specimens, W = 8.10-6 *L3.061 (r2= 0.96) for males, and W= 7.10-7*L3.089(r2= 0.98) for females; growth pattern were allometric over all condition factor were almost the both males andfemales, i.e. 1.0234 and 1.0275 respectively. Based on the segment, males were the highest in March at the middlesegment i.e 1.2105 (n= 49) and the lowest at was the upper segment i.e. 0.8952 (n = 29). In females, the highestwas also in March at the upper i.e. 1.1895 (n = 19) and the lowest in April at the lower segment i.e. 0.9478 (n=35); sex ratio consists of 1073 males and 1393 females or 1: 1.29.Key words: growth, length-weight relationship, condition factor, and sex ratio
