Abstract

Kabupaten Belitung merupakan bagian dari wilayah provinsi Kepulauan Bangka Belitung yang memiliki objek wisata utama berupa wisata bahari. Kabupaten Belitung telah ditetapkan sebagai salah satu Kawasan Strategis Pariwisata Nasional (KSPN) sesuai dengan PP Nomor: 50 Tahun 2011 tentang RIPPARNAS dan ditetapkan sebagai salah satu titik labuh kapal wisata (yacht) dari 18 Pelabuhan di seluruh Indonesia. Oleh karena itu saat ini Pemerintah Kabupaten Belitung merencanakan akan membangun kawasan marina di sekitar Pantai Tanjungpendam. Pembangunan kawasan marina akan menimbulkan dampak terhadap lingkungan baik positif maupun negatif. Sebagai dasar untuk menganalisis dampak lingkungan suatu kegiatan pembangunan diperlukan kajian rona lingkungan awal di sekitar lokasi rencana pembangunan. Salah satu komponen lingkungan adalah lingkungan abiotik yang meliputi lingkungan geofisik dan kimia seperti kondisi geologi, hidrologi, hidro-oseanografi, iklim, kondisi udara dan lain sebagainya. Metode yang digunakan dalam kajian ini adalah kompilasi data sekunder, survei lapangan dan analisis data berdasarkan baku mutu lingkungan. Tujuan kajian ini adalah mengetahui rona lingkungan awal aspek biotik sebagai dasar dalam memperkirakan kemungkinan dampak lingkungan yang terjadi serta mengetahui daya dukung lingkungan untuk pengembangan kawasan marina. Berdasarkan hasil kajian ini kondisi lingkungan abiotic (kualitas udara, kualitas air laut, kualitas air sungai) secara umum memenuhi baku mutu lingkungan yang berlaku. Kondisi hidrooseanografi dan daya dukung geologi (struktur geologi, geologi teknik, geomorfologi) sangat mendukung untuk dibangun kawasan marina Belitung. Kata kunci : abiotik, hidro-oseanografi, kawasan marina, baku mutu lingkungan

Abstract

Indonesia?s disaster potential is very high and varied. Natural conditions, population and cultural diversity in Indonesia cause in increased risks due to natural disasters, man-made disasters and emergencies to be complex, on the other side Indonesia is rich in natural resources. Disaster relief should be directed from pre-disaster phase, during emergency response and post disaster. The initial phase of this effort is the need for understanding of all stakeholders (mainly institutions) about the development of the concept and paradigm change mitigation. By knowing the concept and development of this paradigm is expected that all stakeholders can do things from the smallest to the larger and synergies will occur from all stakeholders to minimize the impact of a disaster. From ancient times until now the concept of a paradigm in disaster management shift very rapidly starting from the conventional to the holistic paradigm. In general, the development paradigm is the conventional paradigm (relief emergency), mitigation paradigm, development paradigm and paradigm of risk reduction. Paradigm that is now growing and effective enough to minimize the risk mitigation is the analogy of mitigation for diseases caused by poor environmental sanitation. The analogy with disease problems mentioned above, there are disasters which can now be viewed in the same perspective, where the current disaster is something that is not predictable and it is destiny or part of the risks of everyday life. The concentration of people and higher population levels worldwide would increase the risk of disasters and multiply the consequences of natural hazards as dangers that arise. However, based on science ?of epidemiology disaster? actually most of these disasters can be prevented or at least many ways to reduce the impact of a disaster (mitigation actions). Like the war against disease, warfare should be fought against disaster by any person jointly and involve society as well as changes in social behavior as well as improvements in individual practices.Keywords : mitigation, disease, environmental sanitation, disaster

Abstract

aat ini pesisir Teluk Semarang mengalami berbagai permasalahan yang sangat kompleks. Permasalahan tersebut adalah rob dan banjir, penurunan muka tanah, dan abrasi pantai. Untuk mengatasi permasalahan tersebut telah banyak konsep diusulkan dan yang paling mengemuka adalah konsep dam lepas pantai dan sabuk/ tanggul pantai sepanjang garis pantai. Untuk merencanakan pembangunan dam lepas pantai ataupun sabuk/ tanggul laut diperlukan data dan informasi terkait kondisi dan karakteristik perairan laut padahal data dan informasi terkait hal tersebut masih sangat terbatas. Oleh karena itu diperlukan survei dan kajian kondisi karaktersitik perairan laut di Teluk Semarang. Metodologi kajian ini adalah dengan mempelajari data hasil penelitian terdahulu, melakukan survey lapangan dan pengambilan sampel sedimen dasar dan sedimen layang serta melakukan analisis di laboratorium. Berdasarkan hasil kajian ini diketahui bahwa kualitas air laut di Semarang secara umum memenuhi baku mutu untuk kegiatan pembangunan pelabuhan, sedangkan untuk kegiatan wisata terdapat beberapa parameter yang melebihi baku mutu terutama yangberada di dekat muara sungai. Kondisi hidro-oseanografi perairan laut di Semarang adalah kecepatan arus kurang 50 cm/dt dengan arah dominan ke barat dan barat daya, kedalaman kawasan kajian mencapai -17 m, tipe pasang surut campuran dominan ke harian ganda. Konsentrasi sedimen melayang di peraiaran laut lepas berkisar 0,028 ? 0,063 gr/l dan di sekitar muara berkisar antara 0,036 ? 0,079 gr/l. Sedimen dasar tergolong pasir halus dengan d50 berkisar antara 0,1 ? 0,23 mm.kata kunci : dam lepas pantai, kualitas air laut, hidrooseanografi

Abstract

Since year 1977 until 2005, PT. ANTAM has been exploited nickel ore resources at Gebe Island Center of Halmahera District North Maluku Province. Mining activity, beside give economically advantages also cause degradation of environment quality espicially water quality. Therefore, it need evaluation activity for change and compare of water quality at GebeIsland after mining activity. In this research we took a field survey and got 4 samples (1 samples for undisturbed water : Niwisyo Lake; 3 samples for disturbed water : Check Dam, Port and Turap Ponds). And then these samples were analyzed at BIOTROP laboratory. Base on this research, the water quality in Niwisyo Lake [only BOD parameter exceed standard] andCheck Dam were classified in Class I [only Ni concentration (0,213 mg/lt) and suspended solid (12,93mg/lt) have high value] , water in port was Class III [only DHL parameter (567 S) has high value] and water ini Turap Ponds was Class IV [only BOD (18,43 mg/l) and DHL (497 S) parameter have high value]. This condition may be caused the rehabilitation activity in GebeIsland has been succeded.

Abstract

Regional spatial planning is done for anticipate increasing and developpingsocial-economic activity. Generally, spatial planning tend to spatial valueand economic value, on the other hand environmental value is ignored. Forexample : in saptial planning is no space for conservation area for rechargearea. For determine (mapping) suitability a zone for recharge area needrequirements or a model for guidelines to determine recharge area. Generallyrequirements or parameter are used for mapping recharge area are materialpermeability, rain intensity, soil, slope and depth of groundwater surface.

Abstract

Jelitik River is the main river and economic artery of Sungailiat District, Bangka Regency. Currently around the Jelitik River there is a Jelitik Fishing Port and is developed as an industrial area. In addition to the problems of sedimentation problems with the development of industrial estates and the presence of sand mining rich in tin ore on land and on the high seas it is feared that it will reduce the quality of the environment, especially the surrounding sea water. Therefore, this study is needed in order to find out the quality of waters in this estuary which can be used as a basis or baseline for the initial environment of this region if later this area will be developed as a port or industrial area. The method used in this study is field observation, water sampling, and laboratory analysis. Therefore, as an initial step, it is necessary to identify the quality of the waters in this estuary which can be used as the basis or initial environmental baseline of this area if later this area will be developed as a port or industrial area. Based on observations in the field of laboratory analysis of water samples, generally the quality of seawater around the estuary of Jelitik River still meets seawater quality standards both for port activities, marine tourism and for biota. Some parameters that exceed the quality standard include total suspended solid (TSS) which reaches 250 mg/l, total dissolved solids (TDS) which reaches 24,700 mg/l and nitrate content which reaches 0.38 mg/l. BOD value is 4.7 mg / l and COD is 46.4 mg / l, these parameters are still below the existing sea water quality standard.

Abstract

Jakarta menghadapi permasalahan lingkungan dan bencana alam, potensi bencana alam tersebut meliputi banjir, gelombang ekstrim, abrasi dan cuaca ekstrim. Land subsidence yang semakin tinggi, sebagai akibat dari konsolidasi tanah dan pengambilan air tanah secara masif menyebabkan potensi kejadian banjir akan semakin meningkat. Dalam rencana pembangunan jangka panjang 2030, Jakarta mempunyai rencana pembangunan Giant Sea Wall (GSW), yang digunakan untuk mengatasi masalah di Jakarta. Pembangunan GSW yang membentang dilepas pantai Teluk Jakarta akan menyebabkan dampak terhadap perairan dan lingkungan. Tujuan dari penelitian ini adalah melakukan kajian perubahan kondisi hidrodinamika di Teluk Jakarta akibat dari pembangunan Giant Sea Wall. Pembangunan GSW berpengaruh sangat signifikan terhadap pola hidrodinamika terutama di dalam tanggul. Fluktuasi muka air laut dan kecepatan arus di dalam tanggul, bersifat sirkulasi tertutup dan hanya dipengaruhi dari debit sungai yang masuk ke tanggul.
