AbstractThis study aimed to determine the composition and structure of Semayang forest and the Importance Value Index (IVI) of riparian forest in its role of reducing the wave rate. The method used is multilevel plot method of 20x20 m for sampling of tree level, 5x5 m for sapling level and 2x2 m for seedling level. The result showed that the highest Importance Value Index at tree level was dominated by 3 species, they were L. javanicum (101,663), M. speciosa (76,201) and G. renghas (65,962). At sapling level dominated by P. indica (102,990). At seedling level dominated by M. pigra (95,004)andP. brevistipitata (70,109). In addition, Semayang riparian forest has an ecological function as a wave retaining. It can be seen based on the vegetation density and horizontal structure of species that make up the forest. Vegetation density is predicted to reduce the rate of Semayang lake waves that occur during flood season. Keywords: Composition and Structure, Riparian Forest, Semayang Lake.

Abstract

The Manggarai tribe who lives in the mountainous area of Ndoso Subdistrict is one of the tribes that still preserve the traditional culture to use natural resources, especially for plants as traditional medicines. Inheritance of knowledge about medicinal plants is very limited because of the media to deliver the information rely on the communication from parents to children and grandchildren to the generations in the family. Therefore, it is necessary to study about ethnobotany of medicinal plants in this community and determine the types of plants used to make traditional medicine. The methods of this research are the exploratory survey method and the PRA (Participatory Rural Appraisal) approach. It is an assessment process that has an orientation to the involvement of the community in this research. The few steps in this study including survey, observation, interview, documentation, collection, identification and preservation by herbarium. There are 89 species of medicinal plants referring to 46 families of medicinal plants that are commonly used. The Manggarai people use wild plants found in the field, forest, and riverbank, and some are even deliberately cultivated. The method of processing medicinal plants commonly used is by boiled, chewed and patched, scraped, twisted, crushed, and without being processed.AbstrakSuku Manggarai yang bermukim pada kawasan pegunungan di Kecamatan Ndoso merupakan salah satu suku yang masih mempertahankan adat dan tradisi dalam penggunaan sumber daya alam khususnya tumbuhan sebagai obat tradisional. Pewarisan pengetahuan tentang tumbuhan obat tersebut dilakukan  terbatas penyampaian lisan dari orang tua kepada anak dan cucu secara turun temurun dalam keluarga. Oleh karena itu perlu dilakukan penelitian tentang studi etnobotani tumbuhan obat oleh masyarakat Suku Manggarai yang bermukim pada kawasan pegunungan di Kecamatan Ndoso yang bertujuan untuk mengetahui jenis tumbuhan apa saja yang digunakan, bagian tumbuhan yang digunakan dan untuk mengetahui bagaimana cara pengolahan tumbuhan obat tradisional. Metode yang digunakan adalah dengan metode survey eksploratif dan dengan pendekatan metode PRA (Participactory Rural Appraisal) yaitu proses pengkajian yang berorentasi pada keterlibatan dan peran masyarakat secara aktif dalam penelitian. Tahapan pada penelitian ini meliputi survey, observasi, wawancara, dokumentasi tumbuhan, koleksi tumbuhan, identifikasi dan pembuatan herbarium. Diperoleh sebanyak 89 spesies tumbuhan obat yang tergolong kedalam 46 famili tumbuhan obat yang biasa dimanfaatkan. Cara memperoleh tumbuhan obat yang biasa digunakan masyarakat Suku Manggarai adalah memanfaatkan tumbuhan liar yang terdapat di pekarangan rumah, hutan serta pinggir sungai bahkan ada juga yang sengaja dibudidayakan. Cara pengolahan tumbuhan obat yang biasa digunakan adalah dengan cara direbus, dikunyah lalu ditempel, diparut, diseduh, diremas, ditumbuk, dan tanpa diolah.Kata Kunci: Etnobotani, Tumbuhan Obat, Suku Manggarai

Abstract

The open-pit mining method has a very large ecological impact. It causes the loss of forest vegetation which decreases CO2 absorption. Measuring the amount of carbon stored in plant biomass can represent the amount of CO2 that can be absorbed in the atmosphere. The objective of this research is to determine the carbon sequestration of Albizia saman and Senna siamea in different age classes at PT MHU Busang Jonggon Block, Kukar, East Kalimantan. Estimation of carbon sequestration in the stands of A. saman and S. siamea was carried out by non-destructive methods using biomass allometric equations while in understorey and litter using the destruction sampling. The results showed that the highest carbon absorption value of A. saman was 314.28 tons/ha which appear at six years old stands and the lowest value was 193.31 tons/ha at three years old stands while the highest carbon absorption value of S. siamea was 113.65 tons/ha which appear at nine years old stands and the lowest value was 24.64 tons/ha at three years old stands. A. saman could be more promising plant species than S. siamea according to its higher level of carbon sequestration and their high adaptation level. All data from this study could suggest several information for increasing carbon sequestration level in forest ecosystem as well as achieving forest rehabilitation purpose.

Abstract

Macaranga beccariana Merr. is an endemic plant of Kalimantan which is no report yet about its biological activity and isolated compounds. Therefore, in order to know the potency of M. beccariana, determination of antioxidant and antimalarial activities along with isolation of bioactive compounds from this plant must be carried out. In this research, the leaves of M. beccariana was extracted using methanol to obtain methanol extract. Furthermore, the extract was separated and purified to obtain compound 1 and compound 2. Based on structure elucidation using spectrometer analysis including UV, 1H and 13C NMR, compounds 1 and 2 which belong to phenolics were identified as 4-hidroxybenzoic acid and 3,4-dihidroxybenzoic acid, respectively. Moreover, antioxidant activity using DPPH (2,2-diphenyl-1-picrylhydrazyl) and antimalarial activity towards Plasmodium falciparum strain 3D7 using Giemsa staining were performed. Rutine and chloroquine difosfat were used as positive controls for antioxidant and antimalarial, respectively. The results showed that the methanol extract of M. beccariana and its isolated compounds (1 and 2) are active for those activities. It can be concluded that the leaves of M. beccariana has good potency as antioxidant and antimalarial agents.

Abstract

Bonylip barb (Osteochilus vittatus Valenciennes, 1842) that belongs to the Cyprinidae family is one of the native freshwater fishes in Indonesian waters. Currently, status of this species in Benanga Reservoir, East Kalimantan is in over-exploited. Fish resources management, therefore, is needed to maintained fish stock in the reservoir based on fish reproductive biology aspects. The purpose of this study was to analyze some aspects of the reproductive biology including sex-ratio, gonad maturity, length at first gonad maturity, spawning season, fecundity, and spawning patterns as basic information for its management. Fish collection was carried out monthly on the third week from January to May 2019 at three stations. The fish samples were captured by using experimental gill nets with mesh size of 1; 1.5; 2; and 3 inches. A total of 278 bonylip barb was caught, consist of 92 males and 186 females. Sex ratio of male and female in the gonad mature stage was 1: 2.4. The average length at first gonad maturity in male and female were 136.08 mm and 137.38 mm, respectively. Peak of spawning occurs during the rainy season in May, with more than 90% of fish in mature stage with GSI in male and female were 6.88%, 13.16% respectively. Total fecundity ranged from 7312-22923 eggs individual-1 and egg diameter ranged from 0.6-1.94 mm. According to distribution of egg diameter, bonylip barb was categoried as a total spawner. Some management strategies that can be carried out are using fishing gears with mesh size above 2 inches, limiting fishing activities in the peak of the spawning season, prohibiting fishing gear using electric shocker and protection the reservoir from erosion.
