Abstract

The aim of this study is to assess the design of physiognomy of riparian trees and the composition and vegetation structure of riparian trees formation in some forest types in Kahala river of Kutai Kartanegara district, East Kalimantan. The method used in this study was the vegetation ecology which the quadrant technique was applied to collect main primary data of the riparian trees. Points of data retrieval were carried out by as much as 3-point observations at the upper, middle and lower of Kahala river basin. The location of each point was marked by GPS with the length of each transect was 1 km away. The parameters of plant composition and structure ware analyzed by measuring density (K-i), frequency (F) and (dominance). The result showed that physiognomy of riparian trees in 3 main locations was mature secondary forest (in the upstream), perupuk forest (the midstream) and early immature secondary forest (the downstream). There were 22 species belonging to 16 families of riparian trees were recorded in Kahala river. The plant species that have high the importance value (I.V) were recoded namely Antidesma ghaemsembilla which 122.8 % (in the downstream) and Lophopetalum javanicum which 58.5 % (in the upstream).Keywords: Kahala River, Riparian Trees and Quadrant Method.

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. Abstrak Ikan nilem (Osteochilus vittatus Valenciennes, 1842) merupakan jenis ikan air tawar famili Cyprinidae asli perairan Indonesia. Saat ini, ikan nilem di perairan Waduk Benanga Kalimantan timur telah diekploitasi lebih.

Abstract

The flood retention pond in the city of Samarinda, is a body of stagnant water (lentik), the flow of water is not so large that it affects the life of the organisms in it. The research was carried out in December 2020 - March 2021 at three stations using the method Purposive sampling. The composition of phytoplankton species consisted of Chlorophyceae, Dictyochophyceae, Cyanophyceae, Bacillariophyceae (Diatom), Euglenophyceae, Dinophyceae, Trebouxiophyceae. There are three classes of phytoplankton with relatively high abundance, namely Chlorophyceae, Cyanophyceae and Bacillariophyceae (Diatoms). At the moment of condition rain the highest species abundance at station 1 was Eutonia sp. from the Bacillariophyceae (Diatom) class, at station 2 the species of Merismopedia punctata from the Cyanophyceae class and at station 3 Merismopedia punctata from class Cyanophyceae. When conditions are not raining, the highest species abundance at station 1 is Eutonia sp. from the Bacillariophyceae (Diatom) class, at station 2 the species of Merismopedia punctata is from the Cyanophyceae class and at station 3 is the Merismopedia punctata species from the Cyanophyceae class. TSI analysis when it rains and does not rain have an average index value ranged from 10,46 – 17,79, the eutrophication status is in the Oligotrophic category. The water quality factor that forces the eutrophication status in this pond is related to the relatively high nitrogen (N) and phosphorus (P) nutrients.

Abstract

Dayak Lun Dayeh is one of local community who lives in East Kalimantan, where they’ve mostly practiced hunting traditionally, has particular ways to find hunting spot and use hunting techniques sustainably. The research about this community was conducted in river bank of Mentarang in order to determine the various kinds of game animal, frequently used hunting ground, and hunting ways of Dayak Lun Dayeh community at two different times, on May-July 2016 and June-August 2021. Research data were collected through open ended interviews (assisted by key informants), field observations and animal photos. Data were presented descriptively by ethnobiology approach. The results showed that this community practices subsistence hunting of wild animals, which comprised of mammals (69-73%), reptiles (14-15%), aves (8%) and amphibians (0-4%). The meat obtained from hunting(s) were consumed as protein source, served as medium in traditional ceremonies or religious rituals based on ancestral teachings. Wild animals such as Cervus unicolor, Sus barbatus, Muntiacus atherodes could be found easily in abpa’ nuvan (salt lick) rather than primary forest, swidden (latii), swidden fallow (included amug, jekau and ripa), farm, river, or secondary forest such as the logging roads of former timber company. Several hunting techniques were applied such as using hunting dogs for tracking the game animals (gelibut), sieging or waiting (gabang) at specific location (abpa’ nuvan), and setting traps (ton).
