Abstract

Currently, protected forest are in the spotlight regarding national food security that can be applied other than in production forest. This study aims a study  ecotourism scenarios development in the Protected Forest of Wosi Rendani (PFWR).  Research using  techniques for observation, interviews and case studies with a mix method approach. Meanwhile, data analysis using a community based ecotourism development based on the potential and threat level. The results showed potential such as flora, abundant water, caves and waterfalls.  Meanwhile, the threat is rather steep slopes with soil characteristics that are not suitable for seasonal farming. The community has a dominant positive and accepting perception and attitude towards the development of ecotourism. Scenarios ecotourism development in PFWR in order to keep functioning as a protected forest, such as: fruit tourism villages, limited cave tourism, communal water reservoirs and limited waterfall tourism. By making a fruit tourism village, the fallow land becomes more productive because it is planted with fruit trees, so that in the future Manokwari becomes a fruit food estate originating from PFWR. Through limited caves tourism and waterfalls, it is hoped that local people's unemployment will decrease, income will increase so that they are able to meet their daily needs properly.  The availability of abundant water by making reservoirs means that the community around PFWR maintains, protects and maintains the conservation of protected forests, because there is a reciprocal relationship if protect the forest, there will be water available.

Abstract

Ijin Pemungutan Hasil Hutan Kayu adalah ijin pemungutan hasil hutan kayu dari hutan produksi pada hutan negara untuk pemenuhan kayu olahan lokal bagi pembangunan daerah, kelompok dan individu/perorangan, serta kesejahteraan masyarakat pemilik ulayat dalam volume, luasan dan waktu tertentu, dan tidak diperjualbelikan. Penelitian ini bertujuan untuk mengetahui jumlah dan luasan IPHHK selama 2018-2019 di Provinsi Papua Barat, penyebaran IPHHK dominan kabupaten kota/distrik, komposisi jenis kayu olahan berdasarkan surat keterangan sahnya hasil hutan, keragaman ukuran kayu olahan lokal, dan perkiraan penerimaan iuran kehutanan dari kayu olahan lokal di Provinsi Papua Barat. Penelitian dirancang dengan studi kasus, data dianalisis dari dokumen Dinas Kehutanan provinsi Papua Barat, dan wawancara responden kunci. Hasil penelitian menunjukkan bahwa IPHHK pada 2018 sebanyak 1.101 izin dengan luasan 5.505 Ha dan volume bahan baku/log 55.050 m3, setara dengan 27.525m3, akan tetapi jumlah izin menurun 38% pada 2019. Empat kabupaten dominan pemegang izin ialah Manokwari, Sorong, Manokwari Selatan, dan Teluk Bintuni. Kayu olahan lokal berdasarkan Surat keterangan sahnya hasil hutan kayu, didominasi kelompok Merbau (90%), diikuti kelompok Meranti (8%), Rimba Campuran (2%) dan nihil untuk kelompok kayu Indah. Merbau berkontribusi sangat signifikan terhadap provisi sumber daya hutan Rp3.2 milyar/tahun. Karakteristik kayu olahan lokal untuk stand kayu lebih bersifat seller market dan untuk mebel bersifat buyer market atau pesanan. Penanaman jenis komersil endemik bagi pemegan ijin perlu dimonitor dan di evaluasi di masa mendatang. Peredaran kayu olahan lokal pada 2018 masih dapat dipenuhi dari penerbitan 1.101 izin pemungutan hasil hutan kayu di Provinsi Papua Barat.

Abstract

This research was conducting to quantify the berberine concentration. Rapid method using 1H-NMR was used to determine berberine quantitative and qualitatively from the crude extract. Tali kuning was collected from Manokwari Papua Barat and powdered with hammer mill. Sonication was employed to extract using methanol at room temperature. 500 µg authentic berberine chloride were dissolved in 5.4 mL methanol-d4 (containing 84.4 µg anthracene). 1H-NMR spectra were recorded in methanol-d4 (99,9%) using JEOL JNM-ECX 500. Each sample was scanned for 100 using the following parameter 0.18 Hz/point, spectral width 14400 Hz, pulse with 4.0 US, relaxation delay 2 sc. Peak areas were used for qualitative analysis and integration of each peach were employed for quantitative analysis. The results demonstrated that 1H-NMR signal pattern of H-13 and H-8 recorded from Tali Kuning, and Amur corktree were well recorded, and in accordance to the berberine chloride standard. Using peak integration of H-13 and H-8, the berberine quantity in Tali kuning is 18.06 mg/g of dried powder, and 22.78 mg//gr for Amur corktree. Berberine percentage based on the weight of oven-dried-extracts was 8.34% (MC 7.54%) and 12.04% (11,54%) for Amur corktree and Tali kuning.

Abstract

This research highlights diversity of macro-features and density of major timber species from Papua. Thirty-one species of air-dried timber with sample size of 13 cm × 6 cm × 4 cm gathered across Papua were used for density measurement and macro-features observation, cover of colors, grain orientation, and wood texture. The results showed that whitish and straw to yellow brown are dominant color of timber mostly harvested from Papua tropical forest. Their grain orientations are mostly straight, while their textures are medium. With regard to their density, Xantostemum spp is the heaviest timber having density of 1,25 g/cm3 while Alstonia scholaris is the lightest species of timber with density of 0.29 g/cm3. Therefore, majority Papua`s timber species studied are classified into light class species or low density timbers. Pulp and paper, veneer, plywood, flooring, meubels, indoor urnitures and handles or woody utensils are the potential uses of these timber species.

Abstract

Hutan alam telah menjadi primadona bagi pendapatan negara sejak masa orde baru dan menjadi urutan terbesar kedua setelah sektor migas. Sistem pengelolaan timber management (TM) melibatkan sektor swasta melalui kehadiran HPH (Hak Penguasaan Hutan) atau yang dikenal saat ini dengan Ijin Usaha Pengelolaan Hasil Hutan Kayu (IUPHHK). Dalam perkembangannya kehadiran HPH/IUPHHK terus mengalami perubahan di provinsi Papua sesuai dengan kebijakan pengelolaan hutan di Indonesia. Merosotnya produksi kayu bulat hutan alam mengacam penurunan PNBP (Penerimaan Negara Bukan Paak) sektor kehutanan terutama melalui realisasi pembayaran tarif PSDH dan DR. Tujuan dari penelitian ini adalah untuk mengetahui tren produksi kayu bulat IUPHHK aktif dan kontribusinya terhadap pendapatan PNBP sektor kehutanan di Provinsi Papua. Metode yang digunakan dalam penelitian ini ialah metode deskriptif melalui teknik wawancara semi struktural dan diskusi terkait faktor-faktor yang mempengaruhi jalannya produksi kayu bulat dan evaluasi penerimaan iuran PSDH, DR, dan IIUPH pada pemegang izin IUPHHK. Hasil penelitian menunjukan bahwa tren produksi kayu bulat (m3) periode 2014 – 2019 bervariasi dimana nilai produksi tertinggi terlihat pada tahun 2015 dengan total realisasi produksi sebesar 1,163,665 m3. Sementara penerimaan PNBP dari periode 2014-2019 terlihat cukup tinggi pada tahun 2015. Perusahaan dengan kontribusi PNBP tertinggi terdapat pada PT. Jati Dharma PI. Hasil analisis tren regresi sederhana antara penerimaan dan produksi kayu bulat masih telihat cukup positif dengan rataan pertumbuhan sebesar 15 persen. Diharapkan dari kajian ini memberikan informasi aktual terkait dampak perubahan regulasi tarif DR dan PSDH yang berpengaruh terhadap pendapatan sektor kehutanan di Papua.

Abstract

Mangrove forests in Bintuni Bay, West Papua, Indonesia, have been managed for timber extraction since 1988 to produce wood chips using a 30-year rotation cycle. The first rotation cycle was completed, resulting in secondary mangrove forests with various stand ages (1−30 years). A large-scale forest inventory was conducted for all harvested blocks to recognize actual standing stock for the 2021−2030 management plan. A total of 434 quadrat plots (20 m x 20 m) covering 17.36 ha each were used to observe forest standing stock. The results present the dynamics of secondary mangrove forests after the initial rotation cycle. At the end of the first cycle (30-year-old stand), secondary mangrove forests provided a volume of 290.12 m3 ha-1 and potential extractable biomass of 203.03 ton ha-1 with mean diameter, basal area, and stem density of 16.91 cm, 29.18 m2 ha-1, and 1,370 stem ha-1, respectively. Annual increment of volume, biomass, and diameter were estimated to be 9.67 m3 ha-1 year-1, 6.77 ton ha-1 year-1, and 0.56 cm year-1, consecutively. The dynamics of secondary mangrove forests could provide significant information in the context of the management plan and implementation of the silviculture system to ensure the sustainability of utilization in managed mangrove forests.

Abstract

Around 12.62% of watersheds in Indonesia are damaged and need restoration immediately to prevent floods, landslides, and other related disasters. This study aimed to evaluate the Wosi watershed and formulate conservation scenarios to improve its conditions. The data collection included hydrology (quantity, continuity, and water quality), land (critical land index, percentage of vegetation cover, and erosion index), socio-economic (population pressure, welfare level, existence, and regulations enforcement), building investment (city classification and water building value classification), and the use of space (protected areas and cultivation areas). The evaluation of carrying capacity used a scoring analysis. The scenarios formulation used the information on potential carrying capacity and conservation strategies. The results suggested that the carrying capacity of the Wosi watershed from 2016-2019 had fallen into "bad" and "very bad" categories. To improve these conditions, the government can assign the riparian areas as a government asset, build ponds and dikes in the flood-prone areas, apply small recharge pond (SRP) on the cacao plantations, and assign Wosi Rendani protected forest (HLWR) as an urban forest. The implementation of these conservation strategies will result in the improvement of (a) the carrying capacity of the Wosi watershed and (b) the status into the "good" category to support environmentally friendly development in Manokwari city.
