Corresponding author: A. Suman, [email protected] Abstract. Intensive exploitation due to high market demand of long-barbel sheatsfish (Kryptopterus limpok), locally known as “selais fish”, has continuously occurred throughout the year, so that it could threaten resources sustainability. Scientific assessment on population dynamic and spawning potential ratio are required as an input to support an apropriate fisheries management. The purpose of this study was to identify population dynamic and spawning potential ratio of the K. limpok with survey method. The study was conducted in Tasik Giam Siak Kecil, Bengkalis and surrounding waters based on data collected during period of survey, from April 2017 to November 2017. Result showed that the length at first capture (Lc) of K. limpok was 18.9 cm (total length) and the size of length at first maturity (Lm) was 19.9 cm. Sex ratio was slightly unbalance (1.0:1.1). The growth rate parameter (K) was 0.59/year with maximum length (L∞) of 43.05 cm. The estimate total mortality rate (Z) was 2.61 per year. While yearly ratio of fishing mortality (F) and natural mortality (M) were 1.41 and 1.2 respectively.

    Indonesia (Republic Of)

    Indonesia (Republic of) Last updated: 31-01-2004 Location and area Indonesia is an island republic and largest nation of South East Asia, stretching across some 5,000 km and with a north-south spread of about 2,000 km. The republic shares the island of Borneo with Malaysia and Brunei Darussalam; Indonesian Borneo, equivalent to about 75 per cent of the island, is called Kalimantan. The western half of New Guinea is the Indonesian province of Irian Jaya (formerly West Irian); the eastern half is part of Papua New Guinea. The marine frontiers of Indonesia include the South China Sea, the Celebes Sea, and the Pacific Ocean to the north, and the Indian Ocean to the south and west. Indonesia has a land area of 1,904,443 km2. (Microsoft Encarta Encyclopedia 2002). According to Geoanalytics (www.geoanalytics.com/bims/bims.htm) the land area of Indonesia comprises 1,919,663 km2. Topography Indonesia comprises 13,677 islands on both sides of the equator, 6,000 of which are inhabited. Kalimantan and Irian Jaya, together with Sumatra (also called Sumatera), Java (Jawa), and Celebes (Sulawesi) are the largest islands and, together with the insular provinces of Kalimantan and Irian Jaya, account for about 95 per cent of its land area. The smaller islands, including Madura, Timor, Lombok, Sumbawa, Flores, and Bali predominantly form part of island groups. The Moluccas (Maluku) and the Lesser Sunda Islands (Nusatenggara) are the largest island groups. The Java, Flores, and Banda seas divide the major islands of Indonesia into two unequal strings. The comparatively long, narrow islands of Sumatra, Java, Timor (in the Nusatenggara group), and others lie to the south; Borneo, Celebes, the Moluccas, and New Guinea lie to the north.

Sixty percent of this rivers are meandering fluvial system which transport and deposit a mixture of suspended and bed-load (mixed load) along low energy. River channel that moving sideways by erosion is undergoing lateral migration and the top of the point bar becomes the edge of the floodplain and the fining-upward succession of the point bar will be capped by overbank deposits of Kampar bend migration on the suspended-load channels of Kampar watershed. This formation consist of succession of fine to medium sand and silt/mud, with root traces, that form as drapes on the prograding bank.

In the search for local definition, some have suggested that it may be found among Riau's suku asli groups - small, indigenous forest-based and aquatic societies that retain strong economic and cultural links to the territories and natural environments that they have occupied for generations. This paper is primarily concerned with issues relating to the identity and cultural survival of one such group - the Suku Petalangan - who number about 20,000 and occupy the once thickly forested Kampar river hinter- lands on the Sumatran mainland where they engage in swidden farming, collecting forest products and fishing. Suku Petalangan leaders have described themselves to me as Melayu asli darat (authentic inland Malays) and rakyat bekas kerajaan Pelalawan (people of the former kingdom of Pelalawan). I have also observed that, depending upon the situation in which identity was an issue, individuals identified themselves or were identified according to their village of birth, clan origin and/or residency.

    Abundance of phytoplankton in the Kampar Kiri River, Mentulik Village, Kampar Kiri Sub-District, Kampar District, Riau Province By Rizki Anita Lubis1), Eni Sumiarsih2), Adriman3) [email protected] ABSTRACT Kampar Kiri River is located in Riau, there are fisheries and domestic activities that potential in affecting water quality. To understand the abundance of phytoplankton present in that river, a study has been conducted in July 2016. Samplings were conducted 3 times, once week, in 3 stations. Results shown that there are 11 species of phytoplankton present in the river. They were classified into three classes, `namely: Bacillariophyceae (4 species), Chloropyhceae (3 species) and Cyanophyceae (4 species). The average of phytoplankton abundance was around 359 ± 1,392 cells/L. While the water quality parameters are as follows: temperature: 30 - 310C, transparency: 15.6 ± 22.6 cm, pH: 6, DO: 3.8 - 4.1 mg/L, nitrate: 0.05 - 0.11 mg/L and phosphate: 0.19 - 0.23 mg/L. Based on the composition of pyhtoplankton, it can be concluded that the Kampar Kiri River water can be categorized as low.

The purpose of the visit was to photograph a Sanskrit inscription at Pasir Panjang, on the north-west coast of the island. On inspection of the inscription, it was evident that the translation published by Dr. J. Brandes in the Notulen van de algemeene en bestuurs-vergaderingen van het Bataviaasch Genoot- schap van Kunsten en Wetenschappen (Minutes of the genera1 and exec- utive meetings of the Batavian Society for Arts and Sciences) (hereafter referred to as Notulen) of 1887, pp. 148-52, was open to question, and that a fresh attempt at translation and interpretation was called for. This article traces the history of the discovery of the inscription by European scholars and the subsequent scholarship on it, then offers a new translation and makes an attempt to understand the inscription in its physical setting. The island of Karimun Besar is approximately twenty kilometres in length and five kilometres in breadth, and lies some fifty kilometres west-south- west of Singapore.
