Abstract

Samudra Indah Beach is one of the developing tourism areas. The development of marine tourism areas has to balance the economic needs and the effective use of resources. This study aims to analyze the suitability level of Samudra Indah Beach as a beach tourism object based on some parameters of the suitability of the tourist area and to analyze its carrying capacity. This study is descriptive using the Index of Tourism Suitability and Carrying Capacity which results in the values of suitability and carriying capacity of the tourism area. The parameters observed include depth, beach type, base substrate type, beach width, beach slope, current velocity, water brightness, land cover, hazardous biota, and freshwater availability calculating the maximum number of visitors accommodated in the area at a certain time without causing disturbance to nature and humans. The results showed that the Samudra Indah Beach area was included in the category of highly appropriate (S1) particularly for beach recreation and swimming. This beach can accommodate around 8,333 visitors/day.

Abstract

By stock assessment, data on the current status of fish resource utilization in nature are obtained, which are used for optimum utilization of fish resources and prevent overuse of fish resources, so that fish resources can be used sustainably. This research was conducted to assess the stocks of mondol stingray stock which included the frequency distribution width, the relationship between width and weight, growth and mortality and the rate of exploitation. This study uses a census method by observing the stingray caught by fishermen. Stingray samples were taken weekly for four months, at the fish landing sites. The data obtained were analyzed using Microsoft Excel and FISAT II software by FAO-ICLARM. The number of mondol rays obtained during the study was 238, consisting of 118 males and 120 females. The wide range of mondol rays obtained was 170-640 mm (male) and 180-810 mm (female), and the weight range was 170-8,405 g (male) and 195-16,877 g (female). The relationship between the width-weight of male and female mondol showed a negative allometric growth pattern. Analysis of the growth of mondol stingrays shows the growth coefficient of male stingrays is 0.38 per year and females 0.40 per year. The mortality of mondol rays was caused more by fishing mortality than natural mortality. The calculation of the exploitation rate of mondol stingray shows the occurrence of overfishing.

Abstract

This study aims to determine the effect of composted coconut coir dust on growth and yield of cayenne pepper on red yellow podzolic soil. This research was conducted in the experimental farm of the Faculty of Agriculture, University of Tanjungpura Pontianak, started from February to July 2014. This study used a field experiment with completely randomized design consisting of single factor i.e composted coconut coir dust, with six level treatments: S1 (800 g/polybag); S2 (900 g/polybag); S3 (1000 g/polybag); S4 (1100 g/polybag); S5 (1200 g/polybag); dan S6 (1300 g/polybag), consists of 4 replications, with 3 plant samples each. The variables observed in this study include, plant height (cm), number of fruit per plant (fruits), the fruit biomass per plant (g), total dry biomass (g), and root volume (ml). The results showed that the application of composted coconut coir dust here not a significanlly affected plant height, number of fruit per plant, the fruit biomass, total plant dry biomass, and root volume.

Abstract

ABSTRACT Mangrove forests in Mendalok Village have an area of 6 ha and ± 500 m2 which have been managed by BUMDes as mangrove tourism, which is named Polaria Tanjungpagar. This study aims to determine the potential of mangrove ecotourism seen from the perceptions, motivations of the society and visitors, knowing the density of the type of mangrove forest vegetation and knowing the suitability of mangrove ecotourism. This research was conducted from July-December 2018 in the mangrove forest area of Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency, using survey, literature study and interview methods. The analysis of the data used in this research was the percentage of perception, motivations of society and visitors, tourist suitability analysis, analysis of attractions of ecotourism activities, analysis of regional carrying capacity and density analysis of mangrove vegetation. The results of the research on mangrove forests in Mendalok Village have ecotourism potential in the form of a high level of community participation for ecotourism activities of 83.33%, having the potential of mangrove resources for ecotourism development in the form of 12 species of mangroves that make the area suitable for ecotourism. The level of mangrove density in trees is classified as medium with a value of 1011.12 ind / ha, the level of saplings and seedlings is classified as a value of 12755.56 ind / ha and 38257.78 ind / ha which means that it has good regenersion and is suitable for ecotourism. Ecotourism suitability index in the area of organic waste flow with a very suitable category (SS), ecotourism areas have a very suitable category (SS) and unmanaged areas have conditional appropriate categories then the carrying capacity of Tanjungpagar Polaria mangrove area can only accommodate 40 tourists person / day. Based on the research findings of mangrove forests in Mendalok Village, it has the potential to be used as ecotourism. Keywords: Ecotourism, Potency, Mangrove

Abstract

ABSTRACTScylla serrata fishing activities in the waters of Kubu Village are conducted continuously by fishermen and it can cause the mangrove crabs to thin out and can cause scarcity. The purpose of this study is to estimate S. serrata's green mangrove crabs, which include sex ratio , carapace width frequency, relationship between carapace width and weight, growth pattern, mortality rate and exploitation rate of S. serrata mangrove crabs. Data and samples were collected in September-December 2018 obtained from the two collectors located in Kubu Village. Analysis of the data processing of this study uses the FISAT II software program (FAO-ICLARM Stock Assessment Toll II). The variables to be observed are sex ratio, carapace width and crab weight, water surface temperature. The results showed that the sex ratio of male and female S. serrata crabs in the waters of Kubu Village was 1.69: 1. The distribution of male carapace crabs in the size of 123.5-130.5 mm, while females were in a wide range of 109.5 -116.5 mm. Analysis of the width and weight relationship produces positive allometric growth patterns in males, and isometrics in females. Male crab has an asymptotic width (L∞) 220 mm, with a growth coefficient value of 0.24 per year, female mangrove crabs have an asymptotic width (L∞) of 218 mm with a growth coefficient of 0.18 per year. The rate of exploitation of male crab is 0.3414 and female is 0.4223 the utilization is still below the optimal value. Keywords: Scylla serrata, Gender Ratio, Growth Pattern, Exploitation.
