Abstract. Asra R, Witono JR, Fijridiyanto I, Elva, Scheu S. 2019. Community study of dragon’s blood palm (Daemonorops spp.) in Harapan Rainforest, Sumatra. Biodiversitas 20: 3632-3640. Dragon's blood palms are rattan species that produce red-colored exudate on its fruit skin, popularly called exudates 'dragon's blood'. It has a high economic value and plays an important role as an income source for indigenous tribes in Jambi, such as in Bukit Duabelas National Park who live Anak Dalam Tribe and Semerantihan Village live Talang Mamak Tribe. However, overexploitation and unsustainable harvesting method have caused its decline in its population in natural forest. This study aims to make an inventory and map distribution of Dragon's blood palms in Harapan Rainforest, at the boundary between Jambi and South Sumatra Provinces, Indonesia; to determine its sex ratio and identify environmental factors that influence sex of Dragon's blood palms. This research used purposive random sampling method at three areas in Harapan Rainforest, i.e.: Hamparan Bato, Hamparan Batang Kapas, and Hamparan between Block A and B. The results showed that three species of Daemonorops were found in Harapan Rainforest, namely Daemonorops didymophylla, D. draco, and D. longipes. D. longipes has the highest population (18 clumps). The highest number of clumps were found in Hamparan Bato (17 clumps)and Hamparan Batang Kapas (17 clumps) areas. The ratio of male and female plants of D. longipes is 1: 1.84, D. draco is 1: 2 and D. didymophylla is 2.2: 1. Most clumps of Daemonorops species in Harapan Rainforest grow on the river banks which have low organic matters. Soil chemical variables that most contribute to the growth of Daemonorops spp. in Harapan Forest are N, C and pH.

The survey research entitled “Constraints faced by Kiwi fruit farmers in Ilam Municipality and Sandakpur Rural Municipality of Ilam District” was conducted to access the problem faced by kiwi fruit farmers of Ilam district. For the study, 80 households were selected using simple random sampling method. 40 households each from Ilam Municipality and Sandakpur Rural Municipality were selected. The study shows that the production is in slightly increasing rate in both Ilam Municipality and Sandakpur Rural Municipality. In both Sandakpur and Ilam areas, 25 and 20 percent farmers are producing seedlings in their own nursery respectively and rest of seedlings requirement is met from other nursery. The major problem was wild animal Kala at Ilam and Sandakpur. Unavailability of quality saplings, lack of male and female plant management in field, lack of modified storage and lack of refrigerator van were major constraints of Ilam Municipality. Lack of cemented support system, lack of training and pruning knowledge, lack of modified storage and poor connectivity of road were major constraints of Sandakpur Rural Municipality. Overall constraints of Ilam was technical factors whereas of Sandakpur was disease and pest constraints.

Kabupaten Pemalang merupakan wilayah yang memiliki potensi perikanan, salah satunya udang Metapenaeus tenuipes. Meningkatnya penangkapan dengan jaring Arad akan mengancam kelestariannya. Tujuan penelitian ini yaitu mengetahui aspek biologi udang M. tenuipes dan status sumberdayanya seperti struktur ukuran, sifat pertumbuhan, dan aspek reproduksi. Metode yang digunakan yaitu metode survei. Metode pengambilan sampel yang dilakukan adalah systematic random sampling. Pengambilan sampel dilakukan empat kali dari bulan Mei-Agustus 2016. Tempat pengambilan sampel di TPI Tanjungsari dan TPI Asemdoyong. Hasil penelitian menunjukkan nilai L50% M. tenuipes jantan 71 mm dan betina 81 mm, ½ L∞ jantan yaitu 60 mm dan betina 75 mm. L50% > 1/2 L∞ berarti ukuran udang yang tertangkap sudah cukup besar sehingga layak tangkap. Sifat pertumbuhan udang jantan dan betina yaitu alometrik negatif (pertumbuhan panjang lebih cepat dibandingkan berat). Nilai faktor kondisi M.tenuipes menunjukan udang betina lebih montok. Tingkat Kematangan Gonad udang M. tenuipes jantan dan betina tebanyak terdapat pada tingkatan I. Perbandingan nisbah kelamin M. tenuipes di Pemalang 1 : 1,33 dengan nisbah tersebut proses reproduksi akan berjalan baik Pemalang is area that has potential one of fishery Metapenaeus tenuipes.

ABSTRAK : Rajungan merupakan komoditas perikanan bernilai ekonomis penting dan memiliki nilai komersial yang cukup tinggi. Salah satu desa yang memproduksi rajungan adalah Desa Betahwalang. Sebagian besar rajungan hasil tangkapan di perairan Betahwalang dikirim untuk di ekspor ke luar negeri. Tingginya permintaan pasar terhadap komoditas perikanan rajungan memicu eksploitasi yang berlebihan sehingga dapat berdampak terhadap kelestarian sumber daya rajungan. Tujuan penelitian ini adalah untuk menganalisis sebaran lebar karapas dan proporsi EBF (egg berried female) rajungan di Desa Betahwalang, Demak terkait dengan upaya pengelolaan rajungan secara berkelanjutan sesuai dengan Peraturan Menteri Kelautan dan Perikanan no. 1 tahun 2015. Penelitian ini dilaksanakan pada bulan Februari – Maret 2019 di Desa Betahwalang, Demak menggunakan metode random sampling. Pengukuran rajungan dilakukan di bakul yang ada di Desa Betahwalang, Demak. Hasil penelitian menunjukkan bahwa 1003 ekor rajungan (83%) yang tertangkap berukuran >10 cm dari total 1203 rajungan tertangkap. Nisbah kelamin di Desa Betahwalang menunjukkan bahwa antara jantan dan betina seimbang (1:1,06). Sedangkan untuk betina bertelur yang tertangkap (EBF) berjumlah 81 ekor rajungan (13%). ABSTRACT : Blue Swimming Crab is one of fisheries commodity with highly important economical and commerce value. One of the village that produce blue crab is Betahwalang. Most of the crabs are exported. With high demand of blue crab resulting in over exploitation that affects the population of blue crab. The purpose of this research is to analyze the spread of carapace width and the proportion of EBF (Egg Berried Female of the blue swimming crab in Desa Betahwalang, Demak that are related with the continuous management effort of blue crab consistent with Peraturan Menteri Kelautan dan Perikanan No 1 Tahun 2015. This research was conducted on February – March 2019 at Desa Betahwalang, Demak using random sampling method. The measurement of blue crab was done on the buyer at Desa Betahwalang, Demak. The results show that 1003 blue crab (83%) that were caught had carapace width more than 10 cm from 1203 blue crab caught. The ratio of male and female crab show that male and female were equal (1:1,06). For the egg berried female (EBF) that were caught shows 81 blue crab caught (13%).
