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.

Abstract

Secara berkala, IUCN mengeluarkan daftar spesies terancam dan status konservasinya melalui Red List. Indonesia juga mengeluarkan Peraturan Pemerintah No. 7 Tahun 1999 menetapkan kriteria penentuan spesies lindung dan status perlindungannya. Kedua ketentuan ini dibuat berdasarkan penilaian ukuran populasi dan ancaman terhadap habitat, serta tekanan pemanfaatan sebagai faktor utama penentuan kriteria keterancaman dan status konservasi spesies. Namun, dalam pelaksanannya kriteria ini sulit dilaksanakan karena keterbatasan data dan informasi sementara tingkat ancaman, terutama perubahan dan kehilangan habitat terus meningkat sejalan dengan peningkatan pembangunan. Penelitian ini mengusulkan suatu pendekatan baru dalam menilai status keterancaman species, terutama menggunakan kriteria yang digunakan IUCN yaitu penilaian atas keadaan habitat (kehilangan dan kerusakan). Pendekatan baru ini diterapkan dalam penilaian ikan pelangi endemik Papua. Penilaian dilaksanakan dengan melalukan tupang susun daerah penyebaran ikan endemik dengan berbagai kegiatan pembangunan, baik yang sedang berjalan maupun dalam tahapan perencanaan dengan Arcgis. Daerah penyebaran yang ditumpang susun dengan berbagai kegiatan pembangunan berskala besar kemudian dihitung luas daerah penyembaran ikan yang terancam. Sebuah matrik dibuat untuk menghitung berbagai ancaman atas habitat atau daerah penyebaran tiap spesies yang dianalisa untuk menentukan tingkat keterancaman spesies dan status konservasinya. Pendekatan analisa ini menyimpulkan ada empat spesies kritis, 11 spesies terancam dan 15 spesies rawan. Pendekatan ini memungkin penilain status dapat dilaksanakan beberarapa spesies bersamaan dibandingkan dengan penilaian yang menggunakan penilain populasi sebagaimana dianjurkan IUCN. Namun pendekatan lebih tepat bagi spesies dengan habitat penyebaran tertentuatau daerah penyebaran telah diketahui, seperti spesies yang terdapat pada danau, pulau atau puncak gunung dan spesies yang daerah penyebarannya telah terpetakan dengan jelas.

Abstract

The mangrove area of the world has been decreasing and Indonesia has lost 1.6 million ha of mangrove during the period 1980-2005. In 2015 the status of Indonesia's mangroves was 3.5 million ha with 48% in good condition and 52% in degraded conditions. Therefore, mangrove forests should be conserved properly and utilized sustainably. Assessment of the status of mangrove conditions is essential in conservation planning and management so that it can be done better. However, the method for assessing the condition of mangrove forests is still diverse and has not been standardized, so a literature review and review of how to assess the condition of mangrove ecosystems from various literature needs to be done. The results of the study of various literatures, in general there are two types of assessments. The first assessment used canopy density indicators, tree density, structure and composition of vegetation including diversity index and environmental parameters which are used singly or a combination of some or all parameters and some that be correlated with ecological integrity. For the second assessment, using a comparison between the existing mangrove forest and the potential area to be overgrown with mangroves. There is a difference when assessing the potential area, there is the opinion of the area potentially seen by the status of the area whether or not the forest area, from the landsystem, the level of abrasion, pond area and the comparison of the coastline length overgrown with mangrove with a total coastline length. Both assessments with each indicator can be used in accordance with the objectives of the assessment of the condition.

Abstract

The continuously increasing population growth more than food agriculture growth on the existing land, has been encouraging to this research. The land use competition for agriculture and housing purposes have caused the land use change from forest to agriculture and housing. Within forested landscapes food production, commodity agriculture, biodiversity, resource extraction and other land uses are also competing for space. The forest land use change (deforestation) is one of the climate change causes. The impact of climate change among others is the uncertain climate, such as the long drought period, flood, and the extreme temperature that cause decreasing in agriculture production. Therefore, at present, many people use the marginal land, such as peat land for agriculture cultivation to increase the food agriculture production and to achieve the domestic and export demand. Indonesia has a huge peat land and the fourth biggest in the world after Rusia, Canada, and America. The focus of this study is comparing the life cycle assessment of three agriculture commodities: sago palm, oil palm, and paddy cultivated on peat land. The purpose of this research is to contribute a recommendation of the most sustainable commodity from the aspect carbon dioxide (CO2) emission among three food agriculture commodities include oil palm and paddy that currently as excellent commodities, and sago palm, the neglected indigenous plant, which are cultivated on peat land. The method applied for this research to analyze the environmental aspect using life cycle assessment (LCA) started from seedling, plantation, harvesting, transportation, and production process. The analysis result reveals that sago palm is the most environmental friendly. The lowest CO2 emission (ton/ha/year) is sago palm (214.75 ± 23.49 kg CO2 eq), then paddy (322.03 ± 7.57 kg CO2 eq) and the highest CO2 emission (ton/ha/year) is oil palm (406.88 ± 97.09 kg CO2 eq).

Abstract

This study aimed to evaluate the Tourism Management CHSE Protocol during the Covid 19 Pandemic in the Situ Gunung Gede Pangrango National Park Area. The framework of the approach used in this research was phenomenology, which was then enriched with the data collection techniques of study documentation, observation, and close-ended questionnaire. The analytical method utilized was the One Score One Indicator Scoring System, an analysis model that was used through developing elaboration of questionnaires in collecting data and evaluating various variables that researchers had determined. Then, two critical issues were examined in the polarization analysis to understand the differentiation between actors, namely polarization of direction and rating scale, and then tested statistically using Kruskal Wallis test to know the polarization significance. Overall, based on the assessment of 189 CHSE indicators, the data shows that the implementation of CHSE in Situ Gunung GGPNP results in a reasonable conclusion or score of 6. When viewed based on stakeholder polarization where the data shows there is no polarization of direction between stakeholders on CHSE management at Situ Gunung. Things are different when viewed in terms of average values, where the study results show the polarization of each actor's attitude scale on the CHSE implementation assessment. The aggressive strategy is carried out by optimizing three crucial aspects: 1) Strengthening CHSE Management Policies and Implementation; 2) Optimizing Ecotourism Carrying Capacity.

Abstract

Macaca maura yang terancam punah hanya ditemukan di bagian selatan pulau Sulawesi. Populasi mereka berkurang secara signifikan karena perusakan dan perusakan habitat serta pembunuhan akibat konflik dengan petani. Penelitian ini bertujuan untuk melihat apa yang menyebabkan terjadinya konflik tersebut. Kemudian kami memilih site yang menjadi lokasi yang tepat untuk belajar. Oleh karena itu penelitian ini mencoba untuk memahami (1) demografi dan kepadatan M.maura di Taman Wisata Alam Lejja (2) memetakan pola persebaran populasi M.maura di Taman Wisata Alam Lejja (3) untuk menggambarkan gangguan/konflik yang dilakukan oleh M.maura di sekitar area perumahan terdekat di Site Lejja. Penelitian ini dilakukan di Taman Wisata Alam Lejja. Data populasi dikumpulkan dengan menggunakan metode Concentration Count dan mewawancarai dua puluh masyarakat sebagai responden yang memiliki perkebunan/permukiman di dekat kawasan konservasi untuk mengumpulkan data gangguan satwa liar. Data dianalisis secara kualitatif melalui penyajian hasil tabulasi dan gambar/diagram. Hasil penelitian menunjukkan bagaimana populasi kelompok M.maura di Lejja beradaptasi dengan berbagai habitat mulai dari hutan, kebun desa dan diantaranya yang memiliki keanekaragaman pakan tumbuhan; Kelompok Panrenge yang populasinya meningkat, seperti yang diperkirakan, memiliki akses yang dekat dengan makanan yang banyak dan beragam di pemukiman dan perkebunan masyarakat. Sementara kelompok lain tampak sesuai dengan kepadatan monyet liar yang diharapkan,pada populasi monyet yang telah dipelajari. Kecelakaan perampokan tanaman telah tercatat di beberapa kebun desa, tetapi pembunuhan kelompok kera ini sampai saat ini tidak terdengar dari masyarakat yang diwawancarai. Tampaknya pendapatan dari pariwisata menggantikan hilangnya hasil panen. Artinya, pendapatan pariwisata dikompensasikan dengan hilangnya hasil panen yang diserang oleh M.maura.

Abstract

Preparation for gibbons before being released into their habitat is crucial. Thus, there is a need for readiness assessment of Javan gibbon with several criteria derived from other species of gibbons to determine individual readiness. Pre-release assessment study for Javan gibbon (Hylobates moloch) had been conducted in January – February 2014, November – December 2014, and March-April 2016 in the Javan Gibbon Center, Mount Gede Pangrango National Park, West Java, Indonesia. The objective of this research was to assess the readiness of Javan gibbon behavior 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 allocations of Javan Gibbon activities were as follow: feeding (18.17±3.34%); moving (22.34±0.53%); resting (46.24±3.84%); socializing (10.13±4.33%); sexual activity (0.59±0.58%); and vocalizing (2.54±0.88%).  The similarities of activity allocation from this study compared by wild Javan gibbons data found as follows: feeding by 33.03%, moving by 90.97%, resting by 61.52%, socializing by 38.09%, vocalizing by 75.02%, and sexual by 44.24%. Based on readiness assessment of 11 Javan gibbons, 3 individuals were considered almost ready for release, while 8 individuals were considered ready. The assessment of behaviors criteria for the readiness of Javan gibbons before release has not existed before. The results of this research are important as a recommendation for the management of wildlife rehabilitation and as a guideline in implementing the rehabilitation and reintroduction program of Javan gibbons.

Abstract

We studied the floristic composition and structure of the logged-over peat swamp forest in the  PT National Sago Prima of PT Sampoerna Agro Tbk. group for future management of the conservation area that has been  set aside by the company.  In January - February 2012, 25 quadrats of 20 m x 20 m were laid out systematically along a transect,  thus covering a sampled area of 1-ha.  The results showed that the study site was a regenerating and developing secondary peat swamp forests having high plant species richness.  The total number of species recorded was 73 species of 38 families, consisting of 49 species (30 families) of trees (DBH? 10 cm ), 42 species (24 families) of saplings (H > 1.5 m and DBH < 10 cm), and 41 species (27 families) of seedlings and undergrowth.  Tree density was 550 individuals/ha, and total tree basal area was 18.32 m2. The Shannon-Wiener’s Diversity Index for trees was high  (3.05)  Two tree species with the highest Importance Values (IV) were Pandanus atrocarpus (IV= 45.86 %) and Blumeodendron subrotundifolium (22.46  %).  The tree families with the highest IV were Pandanaceae (45.86), Myrtaceae (40.37), and Dipterocarpaceae (39.20). Forest structure dominated by trees with a diameter below 20 cm amounting to 408 trees/ha (74.05%). and  D and E strata with height of less than 20 m, and density of 431 trees/ha (78.36%). Jaccard Similarity index among species, showed  strong association between Pandanus atrocarpus and Blumeodendron subrotundifolium  and based on this association combined  with high IVs, the two parameters of species  characterized the forest, hence the forest could be designated as the Pandanus atrocarpus--Blumeodendron subrotundifolium association. Primary forest species with high economic values were still present in the forest. Eleven species can be included in the IUCN Red List, of which Shorea rugosa is in the category of Critically Endangered), Shorea tesymanniana Endangered and  Gonystylus bancanus vulnerable, hence they should  be protected.

Abstract

Perkembangan populasi penduduk berbanding lurus dengan peningkatan jumlah sampah atau limbah. Kota Sorong dengan daya tarik sebagai pintu gerbang Papua membuat perkembangan populasinya meningkat pesat. Sampai saat ini, manajemen pengelolaan persampahan di Kota Sorong belum berjalan dengan baik. Pengelolaan sampah di Kota Sorong belum mencakup seluruh wilayah yang ada. Pesatnya perkembangan dan pertumbuhan wilayah menyebabkan sampah yang dihasilkan menjadi besar. Kelimpahan sampah laut terutama jenis plastik menjadi perhatian dunia karena potensi bahaya yang dapat ditimbulkan terhadap kehidupan di bumi. Penelitian ini bertujuan untuk mengetahui kelimpahan sampah plastik di pesisir Kota Sorong. Metode pengambilan sampel dilakukan dua kali secara sengaja menggunakan transek kuadrat (ukuran 2 x 2 m2) pada lima lokasi atau stasiun penelitian. Hasil Penelitian menunjukkan Kelimpahan sampah plastik pada pengambilan sampel I memiliki range antara 0,47 – 20,26 item/m2 dan pada pengambilan sampel II yaitu 0,36 – 13,64 item/m2. Stasiun I memiliki kelimpahan sampah terbesar yaitu 20,26± 16,56 item/m2 (Pengambilan sampel I) dan 13,64± 11,41 item/m2 (Pengambilan sampel II) dan kelimpahan sampah terendah yaitu 0,13± 0,28 item/m2 berlokasi di Stasiun IV pada pengambilan sampel I dan 0,36± 0,48 item/m2 berlokasi di Stasiun V pada pengambilan sampel II. Sampah plastik yang ditemukan didominasi oleh kemasan makanan, serpihan plastik, kemasan plastik dan botol minuman.
