Abstract

Bali beach is one of the beaches in the Batu Bara, precisely located in the Mesjid Lama Village, Sub-district of Talawi, District of Batu Bara, North Sumatra Province. There is a coastal mangrove forests in this area. Mangrove is a good habitat for mudskipper. The research aims to determine identification and lenght weight analysis of mudskipper. The research was conducted from March until June 2014. The Method of the research is purposive sampling. For fishing example, the stations or area was used consisted of three transects of which are with beaches, mangroves, and rivers. There are four types of fish can be found in those areas, which are Periophthalmus chrysospilos, Periophthalmus gracilis, Boleophthalmus boddarti and Periophthalmonodon schlosseri. If we sorted that length weight relationship were 3.26 cm, 0.91 cm, 3.06 cm, and 3.01 cm.Keywords: Bali Beach, identification, length weight relationship, Mudskipper.

Abstract

Bali Beach is a located in Batu Bara with an area of approximately 637.22 ha which is a coastal area about 30.6% of the total area.This study aims to determine the potential of mangrove ecosystem for ecotourism, calculate the suitability and mangrove ecotourism carrying capacity. This research was conducted in March to April 2014. Research method used was Purposive Sampling for potential mangrove. Using three stations consisted of the first station (located at the eastern area of Bali Beach), second station (located at the middle area of Bali Beach), and the third station (located at the west coast of Bali Beach). The mangrove species found are: Excoecaria agallocha, Avicennia marina, A.lanata, Bruguiera sexangula, B.cylindrica, Rhizophora mucronata, Aegiceras corniculatum, A.Officinalis, R. stylosa, Ceriops tagal with a population density values exceeding 1000 trees / ha. Suitability index tour of mangrove is 69,23%at the first station is with under unconditional category, and at the second station and third station are 94,87% with suitability category. The carrying capacity (DDK) at first station is 12 persons/day, 37 persons/day at second station and 16 persons/day at third station.Keywords : Ecotourism, Mangrove, Bali Beach

Abstract

Sejak 1976 Perum Perhutani telah mengembangkan program Social Forestry. Program ini mengintegrasikan budidaya ikan dan pengelolaan hutan mangrove yang dikenal dengan istilah tambak tumpangsari atau minawana. Penelitian ini bertujuan untuk mendapatkan informasi status ekologis tambak minawana model empang parit dan kelayakan ekonomis tambak minawana dengan memperbaiki kondisi bioteknis pengelolan tambak minawana. Untuk melihat adanya pengaruh dan hubungan kerapatan mangrove pada sistem minawana dengan produksi perikanan di rancang sebuah penelitian berupa rancangan percobaan satu faktor (rancangan acak lengkap).Adapun yang menjadi perlakuan adalah kerapatan mangrove. Kondisi kualitas air saat ini masih layak diperuntukkan bagi kegiatan budidaya. Walaupun ada indikasi terdeteksi logam berat sehingga perlu sistem tandon untuk memperbaiki kualitas air. Secara bioteknis masyarakat penggarap melakukan budidaya secara tradisional dan banyak yang tidak melakukan standar budidaya yang baik. Secara ekonomi sistem minawana saat ini masih bisa untuk dikembangkan untuk meningkat pendapatan masyarakat. Penerapan minawana yang baik dapat meningkatkan pendapatan masyarakat hingga 196,19 %. Since 1976, Perhutani companies have developed Social Forestry Program that integreated fish aquaculture and mangrove forest management that was known as “tambak tumpang sari” or silvofishery”. The objective of this research were: 1) to got information about ecological status of silvofishery fish pond “empang parit” model and economics appropriateness with improve bio technical of silvofishery fish pond management, 2) to knew relationship of mangrove density on silvofishery system with the fisheries productions that was set in a experimental design single factor. The results of this research were as ecological status, the water quality showed still appropriateness for fish pond activity, was found heavy metals indication so that need to improve reservoir system to make water quality better. As bio technical the farmers do as tradisional aquaculture and many of them did not follow a good standart aquaculture. As economic silvofishery system is still can developed to increase peoples incomes. The application a good silvofishery can increase peoples incomes until 196,19%.

Abstract

Mangrove is the living plant community between the sea and the land that was influenced by the tides. Bali beach in Mesjid Lama village, Batu Bara Regency of North Sumatera Province has an area of mangrove forest about 637,22 ha. Bali beach still has a natural mangrove ecosystem. But, the coastal has long been used by the local community as a source of livelihood especially mangrove forest logging. This research was aimed to know the ecological condition of mangrove forest and condition of the mangrove waters. This research is done in March 2014 to Mei 2014. This research is done with a purposive sampling method by taking and observing of biotic components which was mangrove vegetation and the measurement of water quality parameters. There are 10 kinds of mangrove which found in the research location, namely Aegiceras corniculatum, Avicennia lanata, A. marina, A. officinalis, Bruguiera cylindrica, B. sexangula, Ceriops tagal, Excoecaria agallocha, Rhizophora mucronata and R. stylosa. Kinds of mangrove substrate at this research is clay, loam and silty loam. The biggest diversity index is in the station II.Keywords : mangrove, the ecological condition, water quality, Batu Bara District.
