Abstract

Penggunaan lahan merupakan hasil akhir dari setiap bentuk campur tangan kegiatan (intervensi) manusia terhadap lahan dipermukaan bumi yang bersifat dinamis dan berfungsi untuk memenuhi kebutuhan hidup baik meterial maupun spiritual (Arsyad, 1989). Kualitas air adalah istilah yang menggambarkan kesesuaian atau kecocokan air untuk penggunaan tertentu, misalnya: air minum, perikanan, pengairan/irigasi, industri, rekreasi dan sebagainya. Peduli kualitas air adalah mengetahui kondisi air untuk menjamin keamanan dan kelestarian dalam penggunaannya. Penggunaan lahan dapat menurunkan kualitas air, meningkatkan volume dan kecepatan air permukaan, meningkatkan frekuensi air banjir, meningkatkan aliran air dua kali lebih besar dari hutan alam, menyebabkan hilangnya bahan material dan mengakibatkan penurunan air tanah.Oleh karenanya dilakukan studi literatur dari beberapa penelitian mengenaipengaruh penggunaan lahan terhadap kualitas air.Penggunaan lahan disini meliputi penggunaan lahan hutan, pertanian, pemukiman dan industri.Berkurangnya penggunaan lahan hutan seluas 186 ha atau berkurang 3,7%, lahan permukiman meningkat dengan luas 35 ha atau 2,1%, lading atau tegalan meningkat seluas 53 ha atau 3,9%, berpengaruh terhadap penurunan kualitas air.Penggunaan lahan yang ditandai dengan aktivitas masyarakat yaitu permukiman, pertanian dan industri telah memberikan sumbangan bahan organik sehingga mempengaruhi kualitas air.

Abstract

Solid waste problem is happen in many big city, such as Surabaya City. Jemur Wonosari which is participant in Surabaya Green and Clean (SGC) program also have waste management problems. When SGC was conducted, solid waste management is good. However, after the program finished, solid waste management facilities was neglected. In this research we measured solid waste measurement in waste generation and composition from domestic and non-domestic. Also to survey the level of community participation in manage solid waste. The design is quantitative research, data getting from measurement of waste generation and composition also question data to know community participation level in waste management which influenced by internal factors (knowledge, motivation, and environment attitude).The result of research, waste from people in a day is 0,093 kg/person/day. The result of solid waste generation which produced by the community is about 2054,37 kg/day. Waste composition which dominated by food waste, it’s about 43,3%. From the X2 test explain that there is a relation between knowledge, motivation, and environment attitude to community participation and between community participation to solid waste management. The community need to improve composting activities to minimize waste and rise up community participation.

Abstract

The majority (was approximately about 70%) of the Carbon Monoxide (CO) exposure were derived from transportation sector (Damara, et.al, 2017). CO concentration in the air may be caused by anthropological and meteorological factors such as air temperature. This study analysed air quality, air temperature, number of fuel transportation and its correlation. The air quality parameters were CO concentration and air temperature. This study was a quantitative research. CO concentration and Air temperature were measured by CO Analyzer with air temperature sensor inside it. Fuel Transportation was counted by transportation counter. This research was conducted on Weekdays and Weekends at a different time on 07.00-08.00 am, 12.00-01.00 pm, and 4.00-5.00 pm. The results showed that the highest of CO concentrations and air temperature on 07.00-08.00 am, 12.00-01.00 pm, and 4.00-5.00 pm were 71,002 µg /Nm3 and 35 ºC, 20,613 µg /Nm3 and 37 ºC, and 36,646 µg /Nm3 and 35 ºC respectively. Meanwhile the highest number of fuel transportation were 2,442 units, 1,871 units and 2,050 units. There are two site on area of study with CO concentration was exceed national air quality standards according to PP No. 41 of 1999. The Pearson correlation analysis concluded that there are no correlation between air temperature and CO concentration (α = 0.976). Meanwhile there are a correlation between fuel transportation and CO concentration (α = 0,000).

Abstract

AbstractClimate change is a condition of temperature change and rainfall distribution. Extreme climate events or anomalies such as very high rainfall intensity in short time cause floods and landslides. There is no rain in a long time that will cause drought. Flood and landslide disasters are a form of hydrological disaster in this study. The approach to mitigation and adaptation to climate change focused on how to prevent the occurrence of hydrological disasters, namely land reclamation and water conservation. The method of this research was descriptive research. Descriptive research methods aimed at describing, explaining, and validating the phenomena which became the object of this research. From the recapitulation results of the Indonesian Central Statistics Agency, the temperature of the last 25 years has increased dramatically to reach around 7.5oC. While rainfall figures have also experienced significant fluctuations. The ups and downs are not easily predicted, which will have an impact on human activities in daily life. To anticipate the climate change in Indonesia, two policy approaches are used to develop development patterns, namely mitigation and adaptation. In the concept of a mitigation approach based on research results, intermittent irrigation has proven to be effective. The concept of adaptation approach about the development of the database system expected that the primary foundation for the government and the community was the early warning system for disasters. Principally, the ways of handling climate change mitigation and adaptation through land reclamation and water conservation are quite extensive and varied. The latest in the implementation is the reclamation of ex-mining land, the development of agroforestry systems, and rainwater harvesting systems.Keywords: Mitigation, Adaptation, Climate, Conservation, Water.AbstrakPerubahan iklim adalah kondisi perubahan suhu dan distribusi curah hujan. Kejadian atau anomali iklim ekstrem seperti intensitas curah hujan yang sangat tinggi dalam waktu singkat menyebabkan banjir dan tanah longsor. Tidak ada hujan dalam waktu lama yang akan menyebabkan kekeringan. Bencana banjir dan tanah longsor adalah bentuk bencana hidrologi dalam penelitian ini. Pendekatan mitigasi dan adaptasi terhadap perubahan iklim berfokus pada bagaimana menangani terjadinya bencana hidrologi, yaitu reklamasi lahan dan konservasi air. Metode yang digunakan dalam penelitian ini adalah bentuk penelitian deskriptif. Metode penelitian deskriptif memiliki tujuan untuk mendeskripsikan, menjelaskan, dan memvalidasi fenomena yang menjadi objek penelitian. Dari hasil rekapitulasi Badan Pusat Statistik Indonesia, suhu 25 tahun terakhir telah meningkat secara dramatis hingga mencapai sekitar 7,5oC. Sementara angka curah hujan juga mengalami fluktuasi yang signifikan. Pasang surut tidak mudah diprediksi, yang akan berdampak pada aktivitas manusia dalam kehidupan sehari-hari. Untuk mengantisipasi perubahan iklim di Indonesia, dua pendekatan kebijakan digunakan untuk mengembangkan pola pembangunan, yaitu mitigasi dan adaptasi. Dalam konsep pendekatan mitigasi berdasarkan hasil penelitian, irigasi intermiten terbukti efektif. Konsep pendekatan adaptasi tentang pengembangan sistem basis data diharapkan menjadi fondasi utama bagi pemerintah dan masyarakat dalam sistem peringatan dini untuk bencana. Pada prinsipnya, cara penanganan mitigasi dan adaptasi perubahan iklim melalui reklamasi lahan dan konservasi air cukup luas dan beragam. Yang terbaru dalam implementasi adalah reklamasi lahan bekas penambangan, pengembangan sistem agroforestri, dan sistem pemanenan air hujan (rain water harvesting).Kata kunci: Mitigasi, Adaptasi, Iklim, Konservasi, Air.
