Abstract

Pantai Pulau Rangsang di Kabupaten Kepulauan Meranti yang terletak di wilayah Provinsi Riau merupakan pantai yang sangat rawan mengalami abrasi, karena merupakan pantai yang terbuka. Penelitian ini melakukan kajian seberapa besar laju abrasi dan sejauh mana perubahan garis pantai yang terjadi di Pulau Rangsang dengan menggunakan data citra Landsat 24 tahun terakhir. Pengolahan data citra landsat terdiri atas kalibrasi geometrik, pemotongan citra, penajaman citra, dan digitasi, sehingga didapatkan posisi garis pantai untuk masing-masing tahun data. Perubahan garis pantai dari tahun ke tahun dianalisis dengan proses tumpang-susun data pada kurun waktu tersebut. Laju perubahan garis pantai dianalisis dengan pendekatan statistik End-Point Rate (EPR) dengan menggunakan alat bantu Digital Shoreline Analysis System (DSAS). Hasil penelitian ini menunjukkan bahwa sebagian besar pantai utara dan timur Pulau Rangsang mengalami abrasi dengan tingkat abrasi yang bervariasi. Pantai Timur Pulau Rangsang merupakan pantai yang mengalami abrasi paling parah, sedangkan bagian timurnya juga terdapat sedikit sedimentasi. Pada kurun waktu 24 tahun terakhir telah terjadi abrasi di Pulau Rangsang Kabupaten Kepulauan Meranti dengan laju abrasi rata-rata 48,41 ha/tahun, dan laju sedimentasi 10,74 ha/tahun. Hal ini menunjukkan bahwa, pulau Rangsang di Kabupaten Kepulauan Meranti mengalami pengurangan luas daratan yang cukup besar yaitu rata-rata 37.67 ha/tahun. Pantai-pantai kritis yang mengalami laju abrasi maksimum direkomendasikan untuk segera ditanggulangi agar kejadian abrasi tidak berlanjut di tahun-tahun berikutnya.Kata Kunci: laju abrasi pantai, data satelit, DSAS

Abstract

The forest fires that occurred in 2015 were very severe in the past 20 years. The forest fires caused a haze disaster for several months. The depth of groundwater plays an important role as a key in determining the risk of a fire occurring on peatlands. The purpose of this study is to create a hydrological model to predict the depth of the groundwater surface as a parameter for potential fires on peatlands using regression analysis. The location of the research is the village of Sungai Tohor. The data used for modeling are rainfall data and groundwater depth data that have been recorded historically on peatlands by installing SESAME at the research location and obtained data through the website address web.sesame-system.com. Regression analysis was performed using five data length scenarios, namely 1 month, 3 months, 6 months, 9 months, and 12 months to determine the period that could represent the hydrological conditions in the field. The results showed that the regression analysis with data lengths of 1 month, 3 months, 6 months, and 12 months gave the best prediction results for groundwater levels with strong correlation coefficient values of 0.80, 0.93, 0.89 and 0.94. Meanwhile, groundwater level prediction using regression analysis with 6 months length of data gives results with a moderate correlation value of 0.56.Key words: correlation value, groundwater level, peatlands, regression analysis.

Abstract

Bengkalis island is the main island of Bengkalis Regency, Riau Province, where the district capital is located and is the border of Indonesia and Malaysia. Bengkalis island often experiences a reduction in shoreline (abrasion) which can reach 38.02 meter/year and an additional shoreline (sedimentation) which can reach 29.77 meter/year. The process of abrasion and sedimentation occurs as a result of a series of waves that rub against the shore and transport sediment. Sediment transport can take the form of suspended loads, this is what causes the Bengkalis strait to become turbid, turbidity can be bad for the ecosystem and construction around the strait. Is is the necessary to study the effect of significant wave height and turbidity around the Bengkalis strait. This study use Turbiditymeter to collect turbidity data, the equipment will be assembled and placed on the bottom of the straitfor 2 month. The result of this study indicate that significant wave height has a effect on the turbidity at the study site.Keywords: significant wave height, turbidity, turbiditymeter

Abstract

Debris flow is the flow of mixture of water (from rain or other) with a high concentration of sediments slide down through the high slopes. Often, this flow carry large rocks and tree trunks, sliding down at high speed with great destructive force capabilities against anything in its path such as building houses or other facilities that threaten human life. Debris flow is not directly associated with volcanic eruptions, but can occur in volcanic regions and non-volcanic. Kanako 2D version 2.043 is a simulation software that is used as a tool to verify the effects of erosion control by sabo dam in the process of sediment transport during the debris flow. By using the tool, it can be estimated the occurrence of debris flows on the slopes of Mount Sago with simulation. Keyword : Debris flow, Kanako 2D, Sabo dam

Abstract

Land fires are frequent disasters, especially on peatlands. One of the efforts to prevent fire on peatlands is by building canal blocks. The effectiveness of the canal block needs to be analyzed for its effectiveness to find out whether the canal block can prevent peatland fires. Hydraulic conductivity is one of the parameters used to determine the effectiveness of canal block construction. Hydraulic conductivity is the ability of the soil to drain water through it. The purpose of this study is to find out how much the hydraulic conductivity value of peatlands in Lukun Village and to find out whether the canal blocking construction in Lukun Village is effectively built. The results of this study indicate the value of hydraulic conductivity with the Rice and Bower (1976) method is 0.366 m / day - 14.146 m / day. The value of hydraulic conductivity also shows that the construction of canal blocks in Lukun Village is effective in preventing peatland fires.Keywords: Hydraulic Conductivity, Peatland, Rice and Bouwer (1976)
