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

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.

Abstract

Traditional markets are key centers of economic activity and major sources of organic waste generation in Indonesia. This study aims to analyze the volume, density, and composition of organic waste at Markasan Market, Nanga Pinoh, and to identify traders’ participation in waste management. The research employed a quantitative approach through direct measurement and surveys involving 58 traders representing four main commodities: vegetables, fish, poultry, and fruits. Data were collected using observation, interviews, and questionnaires, then analyzed descriptively. The results show that waste generation is dominated by organic waste (>80%) with an average density of 104.68 kg/m³ and a generation rate of 2.74 kg/unit/day. The largest composition comes from poultry feathers, while the smallest is vegetable residue. Traders’ knowledge, facilities, and compliance with waste management are categorized as moderate. The main issues include limited waste facilities, low awareness among traders, and weak regulatory enforcement. The study recommends improving waste storage facilities, formulating stricter regulations, conducting continuous training and awareness programs, and implementing incentive and penalty systems. Additionally, utilizing organic waste for compost, animal feed, or biogas is considered a promising strategy to support 3R (reduce, reuse, recycle) principles and Sustainable Development Goal 12 (Responsible Consumption and Production). This research contributes to developing effective, healthy, and sustainable waste management models for traditional markets and provides a practical reference for local governments and market managers.
