Abstract

A study on carrying capacity in the reservoir of Koto Panjang Hydro-electricPower Plant, Kampar, Riau Province, was conducted on May-October 2009. The studyaims to assess the quality and carrying capacity of the reservoir for the development offloating net cages (FNC) units that can be sustainably implementd. Carrying capacity ofthe reservoir was estimated based on P total and dissolved oxygen availability in thewater, while number of FNC was estimated based on the total P availability against thebiomass of fish in the FNC. Based on its carrying capacity, the number of FNC unitswhich can be exposed in the reservoir during the period of the study is 19,599 – 33,515.units. The existing utilization level for 900 FNC is actually about 2.7-4.6 % of thecapacity. This indicates that FNC is potential to be develoved. Regarding the potency ofpollution from Kampar and Batang Mangat river basin (allochtonous sources) and fromthe existing FNC (autochtonous sources) as well as regression analysis of total P contents,it is precdicted that the carrying capacity of the reservoir will considerably decreaseTherefore, it is recommended that number of FNC to be operated in Koto Panjangreservoir should be gradually reduced approximately to 1.32 % a year, up to a minimumnumber of 19,599 units, especially in the potential utilization zone of the reservoir.

Abstract

Base on the survey and field visiting at the industry location, the state of traditional dockyardindustry in Bagansiapiapi is reported. Traditional dockyards use wood as raw materials for buildingsmall boat of less than 5 GT for cargo or passenger as well as fishing boats. The location of dockyard isbuilt open on the bank of riverine in the coastal area without any covered building. Even facilities in thetraditional dockyard as well as the way to the location are almost no any infrastructure to support it. Thedockyard persists on the wetland environment, swampy area, and unhealthy working condition. Themanagement of the dockyard is family wise as it belong to the one core family, but the boat craftmenmostly extent family. While the technology used mostly is not deliberately heritage from their ancient orotherwise from the long experiences working in the dockyard for many years. The main problem of thetraditional dockyard is the raw wood materials are scare so that difficul to get with high costly price,whilst capital to secure matereials stock unavailable. The consequence, three of four traditional dockyartsurveyed have already or stopping to product a new boat and frustrating to pace the future. The probableeffective idea way out of the situation is to use alterentive boat substitute material such as FRP. Thisidea will be verified by following studies on modern dockyard producing small boat with using alterna-tive non-wood material. It is necessary as a reference for the transformation of the traditional dockyardinto the modern one.

Abstract

Betta (Betta sp.) is an anabantidae fish with sexual development that can be directed at the embryonic and larval stages. One way to direct the sex development of these fish is by using hormone therapy using natural ingredients. Coconut water is one of the natural ingredients that can be used because it contains high potassium. This potassium can convert cholesterol in fish body tissue to pregnenolone which will affect the increase in testosterone production. This study aims to determine the best dose and age group in directing the sex of Betta fish experimentally using a randomized block design (RBD) with 4 treatments and 3 replications. The immersion treatment of larvae in the age group of 3 days, 5 days, and 7 days for 15 hours with a dose of 0%, 10%, 20%, and 30% coconut water was carried out in a 3 L jar containing 30 larvae. The results showed that coconut water was able to influence the increase in the percentage of male betta fish (P <0.05) with the highest value at a dose of 30% as much as 86.26 ± 8.34% and the 3 day larvae age group of 72.78 ± 16.03, and have a different effect on other treatments. In addition, the survival calculated after immersion shows a value of 100%, meaning that coconut water does not have a harmful effect on fish. Based on the results of this study, the best treatment for directing the sex of betta fish is a dose of 30% coconut water with the 3 day age group
