Assessment of carrying capacity Sangalaki Island Natural Tourism Park, Berau Regency
Full text linkSangalaki Island Nature Tourism Park (NTP) is one of the tourist destinations in Derawan. As a conservation area, tourism development in Sangalaki Island NTP must pay attention to the carrying capacity of the area. The purpose of this research is to calculate the carrying capacity in the NTP area of Sangalaki Island. The research was conducted in October 2021 through literature studies, field observations, and interviews. The calculation of the carrying capacity is carried out with the concept of Physical Carrying Capacity (PCC). The PCC of the area in Sangalaki Island NTP is 259 people/day with details of beach tourism 77 people, snorkeling 69 people, diving 44 people, tracking 13 people, and animal watching 57 people. The PCC data can be the basis for the manager to determine the maximum number of visits that can carry out tourism activities at Sangalaki Island NTP. Carrying capacity is intended to reduce the impact of tourism development on the ecological aspects of the area. In addition, the application of environmental carrying capacity is a manager\u27s step to apply the concept of sustainable tourism at Sangalaki Island
Contribution of coffee agroforestry to the income of farmers in Tulungrejo Village, Ngantang District, Malang Regency
Full text linkThe potential for coffee development in Indonesia has great opportunities, supported by high market demand. The purpose of the study was to determine the characteristics of coffee agroforestry and its contribution to the income of farmers in Tulungrejo Village, Ngantang District, Malang Regency. Types of data consist of primary data and secondary data. Primary data were obtained from interviews with 90 respondents of coffee agroforestry farmers who are members of the Forest Farmers Village Partnership Institute (LKDPH). Data processing used quantitative descriptive analysis by calculating production costs, revenues, and income, as well as the contribution of coffee agroforestry to the total income of farmers. The results showed that farmers applied agrisilviculture with a simple system, namely planting robusta coffee (Coffea canephora) under forest tree stands. The value of the R/C ratio is 2.98 where the value is >1, meaning that coffee agroforestry farming provides benefits. The application of coffee agroforestry contributes significantly to the total income of farmers, which is 58.47%. The development of coffee agroforestry is directed at increasing productivity and quality without damaging the shade plants. The policy implications of coffee agroforestry development must involve all relevant parties including the government, entrepreneurs, farmer groups, banks, and cooperatives

Vegetation diversity, biomass, and carbon storage in post-burned lowland forest of Sangatta, East Kutai, East Kalimantan
Full text linkForest fires can reduce biomass, carbon storage, and vegetation diversity. This research aims to obtain information on vegetation diversity, biomass, carbon content, and carbon dioxide equivalent in two lowland forests of Sangatta (East Kutai) that experienced forest fire in 2015 and 2017. The research was conducted in May 2019 by establishing one plot of 100m x 100m in 2015 and 2017 burned forests, respectively, and placed purposively in each site. The plots were divided into 25 sub-plots of 20m x 20m. All trees and saplings within its respected plots were identified and measured, including their DBH and height, while seedlings were identified and counted. The results showed that in 2015 burned forest contained 103 species and 38 families, including 59 species of trees (DBH ≥10cm) from 467 individuals. Meanwhile, in 2017 burned forest, we found 87 species and 36 families, including 69 species of trees from 398 individuals. We also found that three dominants species in 2015 burned forest were Macaranga gigantea with a density of 120 trees/ha or carbon sinks of 25.84 C kg, Melicope lunuankenda with a density of 63 trees/ha or 6.56 C kg, and Shorea seminis with a density/ha of 6 trees or 0.93 C kg. While three dominants species in 2017 burned forest were Alpitonia incana with a density of 165 trees/ha or carbon sinks of 6.87 C kg, Macaranga gigantea with a density of 60 trees/ha or carbon sinks of 6.18 C kg, and Callicarpa pentandra with a density/ha of 43 trees or 2.75 C kg. The estimated biomass, carbon content, and carbon dioxide equivalent in the burned forest in 2015 with a diameter ≥10cm were 102.20 tons/ha, 47.94 tons C/ha, and 175.94 tons CO2 eq/ha, respectively. Meanwhile, biomass, carbon content, and carbon dioxide equivalent in the burned forest in 2017 with a diameter of ≥10cm were 56.56 tons/ha, 26.58 tons C/ha, and 97.56 tons CO2 eq/ha, respectively
Composition, domination, and similarity level of stand among farmers\u27 cultivated blocks at Wan Abdul Rachman Grand Forest Park
Full text linkThe tree species preferred by forest farmers are not always the same, so that in each farmers cultivated block it is possible to form forest stands with a certain composition. The research aimed to analyze the composition of tree species, dominant tree species, and similarity level of species composition among the farmer’s cultivated block. The research was conducted from August until December 2020. Data collection was carried out with a vegetation survey using nested rectangular plots with a sampling intensity of 1%. The data collected includes tree species, tree height, basal area, and individual number of each species. Data were analyzed by calculating density, frequency, important value index (IVI), similarity index (IS), and dissimilarity index (ID). The results showed that the composition of forest garden stands in the farmer’s cultivated block was categorized as heterogeneous (mixed stand) with the number of trees species varying from 12 to 18 species. The total number of tree species were 43, consisting of 17 jungle wood species, 18 jungle MPTS species, and 8 agricultural MPTS species. The forest garden stands were dominated by 4 tree species, namely Gnetum gnemon, Durio zibethinus, Aleurites moluccana, and Myristica fragrans, each of which had an IVI>19.91%. The similarity level of forest garden stands composition was very low with an average IS of 0.27 and an average ID of 0.73. Thus, it can be stated that the forest garden stands among the farmer’s cultivated blocks had different compositions with a difference of 73%. The heterogeneity of forest garden stands needs to be maintained and even developed so that the ecological function of the forest is maintained and the non-timber produced is sufficiently diverse to meet the needs of communities living around the forest
Populasi dan sebaran bekantan (Nasalis larvatus) di Delta Berau
No full textBekantan (Nasalis larvatus) adalah satwa primata langka dilindungi yang populasinya terus mengalami penurunan akibat hilang dan rusaknya habitat. Delta Berau adalah salah satu lokasi penyebaran bekantan yang berada di luar kawasan konservasi yang kurang mendapat perhatian. Penelitian ini bertujuan untuk mengetahui populasi dan sebaran bekantan di Delta Berau dan sekitarnya. Perhitungan populasi dilakukan secara langsung dari sungai (boat survey) pada pagi dan sore hari. Hasil penelitian menunjukkan terdapat 1.350-1.774 ekor bekantan yang terbagi dalam 115 kelompok satu-jantan, 5 kelompok semua-jantan, 1 soliter, dan 5 kelompok tidak teridentifikasi. Faktor koreksi sebagai pengali populasi tertinggi pada habitat riparian dan mangrove masing-masing sebesar 1,33 dan 1,27. Kepadatan populasi bekantan secara umum adalah 6,56 ekor/km2(kisaran: 0,91-93,33) atau 0,59 kelompok/km2(kisaran: 0,13-9,17). Nisbah kelamin kelompok satu-jantan pada tipe habitat riparian dan habitat mangrove masing-masing sebesar 1:5,6 dan 1:6,1. Sebaran bekantan tertinggi berada di wilayah Kampung Pulau Besing (Pulau Besing, Pulau Bungkung, dan Pulau Sambuayan), yaitu sebanyak 42 kelompok 426 ekor atau sebesar 32% dari total populasi bekantan. Populasi bekantan yang tinggi menunjukkan bahwa Delta Berau adalah habitat penting bagi bekantan di Indonesia. Inisiasi pengelolaan habitat bekantan sebagai Kawasan Ekosistem Esensial (KEE) diperlukan, selain perlindungan bekantan secara lokal oleh masyarakat adat setempat sekaligus sebagai upaya melindungi sumber daya perikanan di sekitarnya

Full text linkSulawesi merupakan salah satu pusat keragaman tumbuhan yang memiliki tingkat endemisitas tinggi di kawasan Wallacea. Akan tetapi, penelitian dan deskripsi keragaman suku Araceae pada pulau tersebut belum banyak dipelajari. Berdasarkan penelitian sebelumnya, sebanyak 40 jenis Araceaeterdistribusi di Sulawesi, dengan 15 jenis diantaranya endemik. Penelitian ini bertujuan untuk mengetahui keragaman Araceae asal Sulawesi di Kebun Raya Eka Karya (KREK) Bali dan upaya konservasi yang telah dilakukan. Metode penelitian dilakukan melalui studi pustaka, dokumentasi, dan observasi. Hasil studi menunjukkan bahwa KREK Bali telah mengoleksi Araceae asal Sulawesi sebanyak 41 jenis dan 14 marga dari berbagai provinsi dan yang terbanyak berasal dari Sulawesi Tenggara. Dari 14 marga tersebut, jenis terbanyak yang ditemukan adalah marga Schismatoglottis (10 jenis). Dari seluruh jenis Araceae asal Sulawesi tersebut, 17 jenis (41,46%) telah teridentifikasi sampai level jenis dan 24 jenis (58,54%) teridentifikasi sampai level marga. Dari jumlah 41 jenis tersebut, 28 jenis diantaranya memiliki karakter morfologi yang berbeda dan berpotensi tinggi menjadi jenis baru ataupun catatan baru. Hasil penelitian ini menunjukkan keragaman Araceae di Sulawesi sangat tinggi dan belum banyak terungkap. Usaha konservasi Araceae di KREK Bali masih berupa pengoleksian dan pemeliharaan jenis, belum melangkah pada pemanfaatan yang berkelanjutan dan reintroduksi jenis-jenis yang terancam punah

Full text linkKayu wagha (Archidendron jiringa(Jack.) Nielsen) merupakan salah satu jenis kayu potensial dari Kabupaten Ende, Pulau Flores, Nusa Tenggara Timur (NTT). Penelitian sifat dasar kayu wagha belum banyak dilakukan dibandingkan penelitian wagha sebagai tumbuhan obat. Mengingat kayu wagha digunakan juga oleh masyarakat sebagai kayu konstruksi, oleh karena itu, tujuan dari penelitian ini adalah mengetahui struktur anatomi, sifat kimia, fisis dan mekanik kayu wagha yang diambil dari Desa Nangapanda, Kabupaten Ende, NTT. Pengujian sifat anatomi, kimia, fisis, dan mekanik dilakukan di laboratorium Pusat Penelitian dan Pengembangan Hasil Hutan (P3HH) Bogor. Pengamatan struktur anatomi kayu berdasarkan daftar ciri mikroskopis identifikasi kayu daun lebar (IAWA). Analisis mutu serat kayu berdasarkan pada kelas mutu untuk pulp/kertas. Pengujian sifat kimia kayu meliputi: kadar ekstraktif, kadar selulosa, kadar pentosan, kadar lignin, kadar abu, dan silika. Pengujian sifat fisis dan mekanis kayu mencakup: kadar air, berat jenis, kerapatan, penyusutan arah radial dan tangensial, keteguhan lentur pada batas proporsi dan batas patah, modulus elastisitas, keteguhan tekan sejajar serat, tegak lurus serat, geser sejajar serat, dan keteguhan pukul. Hasil pengujian menunjukkan bahwa ciri utama struktur anatomi kayu wagha adalah memiliki tipe parenkim vaskisentrik, aliform dan konfluen. Komposisi sel penyusun jari-jarinya adalah seluruhnya sel baring, terdapat kristal prismatik, dinding serat sangat tebal dengan kualitas serat kelas II. Kayu wagha memiliki kadar selulosa dan ekstraktif tinggi; kadar lignin, abu dan silika sedang; serta pentosan rendah, sehingga kurang sesuai untuk bahan baku pulp ataupun bioetanol. Kelas kuat kayu wagha tergolong kelas II-I (kuat). Oleh karenaitu kayu wagha cukup potensial digunakan sebagai kayu struktural/konstruksi untuk menyangga beban berat
