Abstract

Kondisi perairan Teluk Kendari saat ini semakin memprihatinkan, padahal kawasan perairan ini merupakan pelabuhan utama di Provinsi Sulawesi Tenggara. Daerah Aliran Sungai (DAS) Wanggu seluas 339,73 km² merupakan DAS penyumbang sedimen terbesar di perairan Teluk Kendari, dengan laju sedimentasi yang semakin meningkat. Kondisi iniakan menyebabkan terjadinya ancaman terhadap kualitas air untuk biota laut dan lingkungan sekitarnya. Penelitian ini bertujuan menganalisis pola sebaran kualitas air laut berdasarkan KepMen LH No.51 Tahun 2004 tentang baku mutu untuk biota laut. Penelitian dilaksanakan pada bulan Juni 2015 berdasarkan parameter nilai pH, DO, kekeruhan dan salinitas yang diukur menggunakan alat Water Quality Checker TOA DKK di 25 stasiun titik pengamatan. Data – data yang diperoleh kemudian disesuaikan dengan baku mutu air untuk biota laut dan selanjutnya dilakukan analisis dengan pendekatan spasial menggunakan Sistem Informasi Geografis (SIG). Hasil yang diperoleh menunjukan nilai pH berkisar antara 8,64 – 8,96 ini berarti kondisi pH berada pada kondisi tidak sesuai untuk biota laut, nilai DO berkisar antara 6,57 – 7,29 mg/l ini berarti kondisi DO berada pada kondisi sesuai untuk biota laut, sedangkan nilai salinitas berkisar antara 11,2-33,5% ini berarti pada stasiun 3, 24 dan 25 berada pada kondisi sesuai untuk biota laut dannilai kekeruhan berkisar 1,8 – 64,4 ntu, ini berarti nilai kekeruhan pada stasiun 8, 10, 11, dan 22 berada pada kondisi sesuai untuk biota laut.KATA KUNCI: Biota laut, kualitas air laut, Teluk Kendari.

Abstract

The fast growth of population, the increased flow of transportation, industry spread in Padang Municipality, and thermal inverse effect can trigger air pollution leading to acid rain in the municipality. The aims of this study are to analyze the nitrate, sulfur and pH contents of rain water and to analyze the effect of rain intensity, air temperature, air pressure, and wind direction and speed on the acidity of rain water in Padang Municipality. The study was conducted using a field measurement and a laboratory test. The sample of rain water was collected by a purposive sampling technique as displayed in Thiessen polygon. The sample of rain water was collected in ten times of sampling in six regions of Thiessen polygon in Padang Municipality. The data collected were analyzed by climate data analysis, rain intensity analysis, multiple linier regression analysis, spatial analysis, and descriptive analysis. The results of the laboratory test showed that sulphate and nitrate contents in rain water in Padang Municipality was still under the threshold of clean water quality No. 416/MENKES/PER/IX/1990, i.e. 400 mg/l for sulphate and 10 mg/l for nitrate. The effect of rain intensity on the acidity of rain water was inversely proportional to sulphate and nitrate contents and directly proportional to pH. The results of validation test and multiple linear regression analysis about the effect of sulphate, nitrate, and pH contents and independent variable as the selected factor displayed in classic assumption test showed that sulphate and pH contents had a significant effect, while nitrate content had no significant effect

Abstract

Mangrove is a plant that can live in tidal areas and form a community of independent vegetation, ranges to various disorders, especially marine resource management that is not environmentally friendly causing damage to the Mangrove forest. Thus researched to know the condition, the rate of change in land area and public response to the mangrove ecosystem implemented in August 2019 using Phantom 4 Drone data and a descriptive method Quantitative. The results were adopted, namely, the condition of the mangrove ecosystem was declared normal (0.22) in the year 2009 using NDVI value classification, as well as the year 2019 NDVI value of 1 in the condition is very good. The area on land cover amounted to 406.61 ha in 2019, while the year 2009 amounted to 406.69 ha with a change of-0.08 ha. Mangrove conditions with an area of 79.13 ha in 2009, a decline in 2019 of 60.01 ha, a change of-19.12 ha (-24.16%). The mangrove ecosystem is getting worse because of the road construction that causes some material to fall into the mangrove area that makes the sedimentation wider, as occurs in the segment 3 The change of mangrove overflow from the year 2009 (21.60 ha) 19.83 ha in the year 2019. People are still promoting the economy compared to the survival of mangroves because the existence of mangroves is considered economically beneficial for them.

Abstract

Climate change and global warming have a negative impact on coastal, especially small islands. Abration and floods can be very danger and need response to minimize the disaster risks. A simple and practical method is needed to inform the location and type of coastal vulnerability and its risks along coastal segments. Smartline is a coastal management method that represents the geomorphology of coastal, hinterland and shoreline. The North Pagai is a small island, a part of the Mentawai Islands that located at the west offshore of Sumatra Island and one of the under developed areas in Indonesia. The island is surrounded by the Hindia Ocean and located on a subduction path of tectonic plate that prone to earthquakes and Tsunami. High rainfall, strong winds, the complexity of coastal morphology and also the majority of coastal residents and limited infrastructure make the problems more complicated. Tsunami in 2010 (7.7 Mw) caused the change of shoreline getting worst on The East Coast of The North Pagai Island. This study aims to identify the coastal vulnerability using Smartline method. The research was conducted on April and September 2016. The result concludes that physical aspect shows Saumangaya and Matobe Village at high and also very high level of vulnerability hence Sikakap Village at very high level. The socio-economic aspect shows that The Sikakap Village is more advanced but contrary more vulnerable to disaster in terms of population density and complex activities. The North Pagai Island is a vulnerable island from physical and socio-economic aspects.

Abstract

The Kampar River estuary is well known for a tidal-bore phenomenon called ‘Bono waves’. The emergence of Bono waves has a significant influence on the estuary system of Kampar River. Scoured materials, resulting from the hydraulic jump of the tidal bore, are carried into the middle of the river. These materials are then deposited when the velocity of the river decreases as a result of the collision of the tidal current from the sea and the river flow. The aim of this was to determine the area of erosion and sedimentation with respect to the river line and perform land-cover change analysis for the area around the Kampar River estuary for the years of 1990, 2007, 2010 and 2016. The method employed was the supervised maximum likelihood (SML) classifications, which uses an overlay technique to yield alternate information on the river line and land-cover changes in the form of time-series data. The largest erosion occurred during 1990–2007, for which the average change reached 2.36 ha/year. The smallest erosion occurred during 2010–2016, when the change reached 0.41 ha/year. The largest land-cover change was found during 1990–2016, which occurred in the land for agriculture/plantations (11.57 ha/year), building/settlement (48.11 ha/year) and scrubland (30.88 ha/year). The other types of land cover, such as bare land and sediment deposition, varied every single year. The changes to the river line are caused by land-cover changes, and the Bono waves that lead to erosion and sedimentation that is not stable in the middle of the river and downstream.
