Abstract Pasak bumi (Eurycoma longifolia) is a medicinal plant with various benefits and has long been used to cure various diseases such as cancer, gingivitis, intestinal worms, and anti-inflammatory anti-malarial, and tonic after childbirth. The root has high economic value leading to unsustainable harvest and drastic population decline. As initial data in conservation activities, information regarding the association of pasak bumi in Batang Lubu Sutam natural forest has not been obtained. Therefore, this research was conducted to determine the pasak bumi distribution and its association within their natural habitat in Batang Lubu Sutam forest. The study was conducted by using the vegetation analysis method using a plotted path determined by purposive sampling. Data analysis was performed by calculating association indices, including the Ochiai index (Oi), Dice index (Di), and Jackard index (Ji). The results showed that pasak bumi were found in the seedling and sapling stage in the research location and form a degree of association with several plants. The species that formed the highest degree of association with the pasak bumi at both levels of regeneration was Shorea leprosula with an Ochiai index value of 0.85 at the seedling level and 0.94 at the sapling level.

Abstract Eurycoma longifolia is one of the potential medicinal plants and has a high economic value if developed. The bioactive compound produced by E. longifolia has potential as medicine, thus causing increased exploitation of their habitat. This condition resulted in the decreasing population of E .longifolia in nature. The distribution of E. longifolia is influenced by soil fertility conditions. The presence of phosphate solubilizing fungi and cellulolytic fungi in the soil can support the growth of E. longifolia in nature. The purpose of this study was to calculate the population of phosphate solubilizing and cellulolytic fungi and to identify the types of phosphate solubilizing and cellulolytic fungi found in the soil under E. longifolia stands. Soil samples were taken randomly at a depth of 0–20 cm in a natural forest of Papaso Village, Lubu Sutam District, Padang Lawas Regency, North Sumatra. Population and isolation of phosphate solubilizing and cellulolytic fungi were obtained by dilution methods. The isolates obtained were identified morphologically to the genus level by macroscopic and microscopic observation of colonies. The results showed that the population of phosphate solubilizing and cellulolytic fungi were 6.64 × 104 CFU/mL and 9.31 × 103 CFU/mL, respectively. The isolation results in 11 isolates of phosphate solubilizing and 10 isolates of cellulolytic fungi. Based on the morphological identification of phosphate solubilizing fungi isolates consisted of 5 genera, namely Aspergillus, Penicillium, Rhizopus, Fusarium, and Mucor, while isolates of cellulolytic fungi also included 5 genera, namely Aspergillus, Cladosporium, Penicillium, Rhizopus, and Mucor.

Long jack (Eurycoma longifolia) is a medicinal plant that has become a common target for exploitation, leading to a population decline in natural forests. This study aimed to determine the stand structure and regeneration status of E. longifolia tree habitat in Batang Lubu Sutam Forest, Padang Lawas, North Sumatra. The research was performed through vegetation analysis using a purposive sampling technique with a randomized sample plot based on the presence of E. longifolia. A total of 181 plots were established in this study. The results showed that the horizontal structure of tree species in the research area had an inverted J-shape pattern, indicating that the number of trees decreased as the diameter increased. The vertical structure showed that all strata were found in the research location, dominated by stratum C. This condition indicated that the forest was in good condition. The regeneration status of 48 species in the location showed different categories. Thirty species (62.50%) were classified as good regeneration, ten species (18.75%) as new regeneration, and four species (8.30%) as poor and no regeneration. The high proportion of trees with good regeneration showed that the forest community could survive despite environmental or anthropogenic stress.

Abstract. Silalahi M, Nisyawati, Pandiangan D. 2019. Medicinal plants used by the Batak Toba Tribe in Peadundung Village, North Sumatra, Indonesia. Biodiversitas 20: 510-525. Research of the medicinal plants by the Toba Batak ethnic has limited, even though the globalization and modernization resulted to degradation of the local knowledge. The objectives of this study were (i) documentation of medicinal plants used in the traditional therapies by the Batak Toba tribe of Peadundung Village, North Sumatra, Indonesia, and (ii) analysing the data by quantitative ethnobotanical tools such as use value (UV), cultural significance index (CSI), relative frequency of citation (RCF) and informant consensus factor (ICF) to determine the cultural importance of medicinal plants in order to develop a tool for their conservation. Semi-structured interviews with 41 identified respondents was the methodology employed for qualitative data collection. A total of 149 medicinal species of plants, belonging to 131 genera and 55 families, were recorded in the study which are used in the treatment of 21 categories of ailments. Plants with the highest UV were Eurycoma longifolia (UV=3.44), Curcuma longa (UV=2.67) and Zingiber officinale (UV=2.60). Eight species, namely Curcuma longa, Eurycoma longifolia, Allium cepa, Psidium guajava, Aleurites moluccanus, Piper betle, Citrus hystrix and Uncaria gambir were found to be having the highest RCF value of 1.00. Eurycoma longifolia (CSI=126), Curcuma longa (CSI=112) and Zingiber officinale (CSI = 105) emerged as the culturally most significant medicinal plants. Thrush and aphrodisiac use categories received the highest ICF of 1.00 each because the informants agreed of using only a single species for each of these categories. Eurycoma longifolia was used as an aphrodisiac whereas Averrhoa carambola was used against thrush. All these important and significant plants suffer the greatest harvesting pressure, hence their conservation should be given priority.

Hiu botol merupakan jenis ikan hiu yang bernilai ekonomis tinggi, karena dapat menghasilkan minyak ikan dari ekstrak hati dinamakan squalen. Pada umumnya, hiu botol hidup di perairan Samudera Hindia pada kedalaman lebih dari 100 meter, namun sampai saat ini penyebarannya belum banyak diketahui. Selain itu, informasi terkait komposisi jenisnya masih sangat terbatas. Tulisan ini bertujuan mengkaji komposisi hiu botol yang tertangkap rawai dasar dan daerah penangkapannya di perairan Samudera Hindia yang berbasis di Kupang, Nusa Tenggara Timur. Data diperoleh dari survei lapangan dan wawancara dengan nelayan penangkap hiu di daerah Tenau, periode bulan Januari-Desember 2016. Hasil kajian menunjukkan bahwa hiu botol yang menjadi target penangkapan terdiri atas tiga jenis yaitu; Centrophorus squamosus (10-13%), Centrophorus granulosus (15-20%), dan Centroscymnus coelolepis (sekitar 40%). Prosentase hiu botol yang di Samudera Hindia berkisar 0,01-0,04 % dari total tangkapan yang didaratkan di Pelabuhan Perikanan Pantai Tenau. Sedangkan, prosentase hiu botol periode tahun 2011-2014 relatif besar dibandingkan dengan hasil tangkapan jenis hiu lainnya. Namun, pada periode 2012-2014 hasil tangkapan hiu botol cukup fluktuatif dan cenderung menurun. Hal ini mengindikasikan bahwa populasi sumber daya jenis hiu ini telah terjadi penurunan. Hasil tangkapan hiu botol tertinggi terjadi pada bulan Januari-Februari dan Agustus-September, yang tertangkap di wilayah perairan Selatan Pulau Rote, Timor dan Sabu. Daerah penangkapan potensial hiu botol berada pada koordinat 1240-1280 BT dan 100-110 LS pada kedalaman antara 200-800 meter. A dogfish shark has a high economic value, especially its liver oil, namely squalen. In general, a dogfish sharks live in the waters of the Indian Ocean at a depth of over 100 meters, but its distribution and composition has not been well documented. This paper aims to describe the composition of sharks caught by bottom longlines operated in the Indian Ocean landed at Kupang, East Nusa Tenggara. Data obtained from field surveys and interviews with shark fishermen from Tenau in January-December 2016. The results showed that the dogfish shark consisted of three species: Centrophorus granulosus, Centrophorus squamosus and Centroscymnus coelolepis. The percentage of dogfish sharks in the Indian Ocean ranged from 0.01 to 0.04% of the total catch landed at Tenau. While the percentage of dogfish shark in period 2011 - 2014 was relatively large compared to the catch of other species of sharks. However, in period 2012 - 2014 dogfih shark catches fluctuated and tended to decrease. This indicates that the population decline of this species. The highest catches of dogfish shark occurred in January-February. During August-September sharks were caught in the territorial waters of the South Island of Rote, Timor and Sabu. Potentially fishing areas of dogfish shark would be located at 124o-128o E and 10o-11o S with depths between 200-800 meters.

Ikan uceng (Nemacheilus fasciatus) merupakan salah satu spesies ikan air tawar di Indonesia dengan nilai ekonomi cukup tinggi yang ketersediaannya masih mengandalkan penangkapan di alam, sehingga diperlukan upaya domestikasi untuk menjaga kelestariannya. Tujuan dari kegiatan ini adalah untuk mengamati biologi reproduksi dan pola pertumbuhan ikan uceng di lingkungan buatan (akuarium). Ikan uceng hasil tangkapan alam dari Sungai Progo, Temanggung, Jawa Tengah (panjang total 5,55 ± 0,53 cm; bobot 2,49 ± 0,24 g) diadaptasikan selama 12 bulan di akuarium (40 cm × 30 cm × 30 cm) dengan sistem air mengalir yang dilengkapi dengan aerator. Ikan uceng diberi Tubifex, hingga sampai akhirnya dapat beradaptasi dengan pakan komersial. Pakan komersial yang diberikan yaitu sebesar 3% per hari dari biomassa tubuh dengan frekuensi dua kali sehari. Data biologi reproduksi diperoleh melalui koleksi data panjang total, bobot badan, bobot gonad, fekunditas, diameter telur, dan indeks kematangan gonad. Data pola pertumbuhan diperoleh dengan koleksi data panjang, bobot, dan sintasannya. Hasil penelitian menunjukkan bahwa induk betina yang gonadnya berkembang mempunyai warna bintik hitam yang jelas, sebaliknya induk jantan warna bintik hitam memudar. Indeks kematangan gonad (IKG) yang diamati pada ikan uceng setelah 12 bulan pemeliharaan yaitu berkisar antara 0,007-0,027 pada jantan dan 0,13-0,25 pada betina. Kisaran diameter telur yang diamati yaitu berkisar antara 0,61-0,68 mm, dengan fekunditas 680-4.198 butir. Sedangkan pola pertumbuhannya menunjukkan bahwa ikan uceng betina dan jantan memiliki pola pertumbuhan allometrik negatif (b= 2,739 pada betina; b= 2,895 pada jantan). Nilai faktor kondisi Fulton (K) pada ikan uceng yang diamati yaitu 0,44-1,07 (rata-rata ± SD: 0,70 ± 0,11) pada betina dan 0,37-0,72 (rata-rata ± SD: 0,60 ± 0,06) pada jantan. Dari pengamatan ini ditemukan bahwa proses perkembangan kematangan gonad ikan uceng di akuarium lebih lambat dibandingkan ikan uceng di habitat aslinya.Barred loach (Nemacheilus fasciatus) is one of native fish species in Indonesia with high economic value, where their availability still depends on wild capture. Thus, domestication is needed to maintain its sustainability. The purpose of this study was to observe the reproductive biology and growth pattern of barred loach reared in aquarium (artificial environment). Fish were collected from Progo River, Temanggung, Central Java (total length of: 5.55 ± 0.53 cm; body weight: of 2.49 ± 0.24 g). The fish were reared for 12 months in aquarium (40 cm × 30 cm × 30 cm) with flowthrough system and equipped with aeration. The fish were fed with Tubifex until they accepted commercial feed. Then, the fish were fed twice a day at a ratio of 3% from the total fish biomass. The reproductive biology data were collected by measuring their total length, body weight, gonad weight, fecundity, egg diameter, and gonadosomatic index. Growth pattern were measured from length, weight, and survival. The results showed that matured female had shown black spot and male had inconsistent formation of black spots on their body. The gonadosomatic indexes ranged between 0.007-0.027 for male and ranged between 0,13-0,25 for female. The egg diameters ranged between 0.61-0.68 mm, with the fecundity of 680-4198 eggs. The result of observation on growth pattern showed that female and male had negative allometric growth (b= 2.739 for female, b= 2.895 for male). The value of Fulton condition factor (K) in the observed fish was 0.44-1.07 (mean ± SD: 0.70 ± 0.11) on female and 0.37-0.72 (mean ± SD: 0.60 ± 0.06) on male. From this study, it was found that gonad maturity development of barred loach reared in aquarium was slower than those in their natural habitat.
