Abstract

Ekosistem mangrove merupakan ekosistem di daerah pesisir tropis dan subtropis yang berperan penting sebagai ekosistem pelindung pantai dari abrasi dan tsunami; produsen makanan bagi makhluk hidup pesisir serta ekosistem penyerap dan penyimpan karbon bagi ekosistem pesisir. Sebagai penyerap dan penyimpan karbon, mangrove dapat menyimpan karbon lebih banyak dari hampir semua ekosistem di bumi, sehingga ekosistem ini dapat berperan penting pula dalam upaya mitigasi pemanasan global. Mangrove dapat menyimpan karbon lebih banyak dari hampir semua ekosistem di bumi. Hampir 40% dari biomassa pohon adalah karbon, dimana melalui proses fotosintesis dapat menyerap karbon dioksida dari atmosfer dan mengubahnya menjadi karbon organik (karbohidrat).   Penyimpanan karbon pada ekosistem mangrove dapat dalam biomassa vegetasinya seperti dalam batang, daun, akar, umbi, buah dan lainnya. Estimasi potensi penyimpanan karbon dalam vegetasi mangrove sebagai mitigasi pemanasan global, menjadikan indikator penting bagi konservasi ekosistem mangrove. Kata Kunci : Mangrove, Pemanasan Global, Dampak

Abstract

Saat ini pelayanan air bersih oleh PDAM Ketapang untuk penduduk Kecamatan Benua Kayong melalui fasilitas sambungan rumah masih sangat minim, yaitu sekitar 11,95% dari jumlah penduduk di Kecamatan Benua Kayong walaupun wilayahnya memiliki banyak sungai. Pertumbuhan penduduk yang bertambah berdampak terhadap besarnya kebutuhan air. Diperlukan pengembangan sarana dan prasarana dalam penyediaan air bersih yang lebih besar untuk mencukupi kebutuhan penduduk di Kecamatan Benua Kayong. Sistem perpipaan akan berpengaruh terhadap elevasi jalur transmisi sehingga penentuan jalur transmisi yang efisien sangatlah penting direncanakan. Penentuan jalur transmisi dilakukan berdasarkan hasil survei di lapangan yang dihubungkan dengan data spasial, seperti peta topografi dan peta tata guna lahan. Jalur transmisi air baku untuk IPA Muliakerta ada 2 jalur alternatif dengan panjang transmisi dan penggunaan lahan yang berbeda. Jalur transmisi terpilih adalah alternatif 2 dengan panjang transmisi 17,4 km.Kata-kata kunci:   transmisi air baku, Kecamatan Benua Kayong, PDAM Ketapang, IPA Muliakerta

Abstract

This study focuses on the impact of tidal sand mining on the water quality of the Kapuas River. The research methods include laboratory tests for parameters such as Water Temperature, Turbidity, DO, BOD, COD, TSS, pH, and Color, as well as field measurements using equipment such as Current Meters, ropes with weights, Sechhi Disks, air temperature, and GPS to record sampling locations. The results of the analysis showed a significant increase in BOD and COD values ​​at point A9, 200 meters downstream from the mining location, due to suction and overflow of water from pontoon boats. Despite the increase in values, the DO value indicates that the water quality is still good, although not comparable to the increase in BOD and COD. The influence of water discharge is an important factor, where high water discharge, especially at points A7, A8, and A9, results in dilution and decreased concentration of pollutants. Parameter analysis shows a decrease in water quality in spots, indicating a source of pollutants that may be diffuse. However, the average Pollution Index value shows that the water quality meets class III quality standards. Kapuas River water can still be used for fish farming, livestock, agricultural irrigation, and other related purposes. The importance of monitoring and mitigation to minimize the negative impacts of tidal sand mining on water quality and maintain environmental sustainability.

Abstract

In the era of globalization and rapid technological development, sustainable development has become crucial for a country's growth, especially in the tourism sector, which has significant potential to drive economic growth and environmental conservation. This research aims to examine how environmental externalities from the tourism sector can be effectively managed through the application of green economy principles. The method used is a qualitative approach with literature study, which includes analysis of the concept of green economy, the impact of tourism on society, and policies that can internalize negative impacts. The research results indicate that the application of green economy principles can reduce negative externalities caused by tourism, such as pollution and ecosystem damage, while also improving the welfare of local communities. Policies such as Pigovian taxes, subsidies, and regulations are necessary to support this implementation. Therefore, sustainable tourism management through green economy not only focuses on economic profit but also on environmental and social sustainability.
