Abstract

Wilayah perairan Indonesia meliputi laut teritorial Indonesia, perairan kepulauan, dan perairan pedalaman. Laut sebagai komponen wilayah yang utama dari negara kepulauan perlu mendapat perhatian khusus. Sistem Informasi Geografis (SIG) merupakan suatu sistem berbasiskan komputer yang digunakan untuk menyimpan dan memanipulasi informasi-informasi geografis, termasuk di dalamnya penilaian proporsi laut. Penelitian ini menyajikan aplikasi pengolahan peta digital untuk menghitung luasan suatu wilayah, dengan tujuan memperoleh angka proporsi laut Indonesia. Hasil yang diperoleh adalah proporsi wilayah laut terhadap luas keseluruhan NKRI adalah 76,94 %. Dari keseluruhan laut tersebut yang menjadi kewenangan pusat adalah 78,86 % dan kewenangan daerah adalah 21,14 %.Kata Kunci: SIG, luas laut, proporsi, wilayah NKRIABSTRACTIndonesian waters area includes the Indonesian territorial sea, archipelagic waters, and inland waters. Sea as a major component of the area of the archipelagic nation needs special attention. Geographic Information Systems (GIS) is a system (computer-based) that are used to store and manipulate geographic information, including the proportion of marine assessment. This study presented the application of digital map processing to calculate the area of a region, with the aim of obtaining the proportion of Indonesian sea figures. The result showed the proportion of sea area to the total area of the Republic of Indonesia was 76.94 %. Of the whole sea under the authority of the cental government was 78.86 % and 21.14 % was in the regional government authority.Keywords: GIS, sea area, proportion, Indonesia region

Abstract

Wakatobi Regency has a huge capacity in natural resources with its beautiful and pristine coastal ecosystems that host 25 coral reefs species in diverse forms. The regency is considered as the world’s best biosphere and frequently visited by local and international tourists for diving/snorkeling. The objectives of this study are to determine the role of marine tourism in Wakatobi’seconomy and formulate an appropriate and strategic policy for its marine tourism development plan. Methods used in this research are theLocation Quotient (LQ) analysis to determine the relative ability of a sub-area to a wider area in the specific sector, and theProspective Participatory Analysis for preparing the marine tourism development plan. The LQ analysis for the marine tourism (trade, hotels, and restaurants) sector based on GDP data from 2004-2007 shows values ranging from 0.808-0.881, which indicate poor potential and low contribution of this sector toWakatobi’s economy. TheProspective Participatory Analysis involving 18 variables related to marine tourism development indicates that Wakatobi Regency has four key variables. These are:community behavior towards environmental protection, community character, human resources andmotivation. These variables would play an important role in preparing and implementing marine tourism development plan in Wakatobi Regency.

Abstract

Dari hasil relokasi kejadian gempa yang tercatat oleh Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) dan inversi data Global Positioning System (GPS) menunjukkan bahwa terdapat celah seismik (seismic gaps) di selatan Jawa, yaitu wilayah di sepanjang batas lempeng aktif yang tidak mengalami gempa besar atau gempa selama lebih dari 30 tahun. Pada zona tersebut diperkirakan terjadi penguncian (locked) terhadap pergeseran lempeng (slip deficit) yang berakibat pada akumulasi pengumpulan energi dan berpotensi menimbulkan gempa megathrust yang bersifat tsunamigenik. Pada penelitian ini dilakukan pemodelan numerik tsunami menggunakan persamaan gelombang shallow water 2 dimensi dengan 3 skenario gempa megathrust akibat patahnya lempeng samudera di zona celah seismik selatan Jawa. Skenario patahan lempeng di selatan Jawa Barat menyebabkan gempa dengan Mw 8,9, di selatan Jawa Tengah dan Jawa Timur sebesar Mw 8,8, dan untuk skenario patahan dari Jawa Barat sampai Jawa Timur sebesar Mw 9,1. Dari hasil simulasi selama 10 jam menggunakan software TUNAMI N2, dihasilkan gelombang tsunami setinggi maksimum 6 meter di pesisir selatan Jawa untuk gempa berkekuatan Mw 8,9, 12 meter untuk gempa berkekuatan Mw 8,8, dan 20 meter untuk gempa berkekuatan Mw 9,1. Propagasi dan travel time tsunami diamati oleh outlet-outlet ARLINDO berupa shallow pressure gauge (SPG) yang ditempatkan di jalur-jalur ARLINDO.
