Selecting methods for water resources in coastal area: Comparative study cases of Hong Kong and Jakarta
Get PDFEnvironmental problems in coastal areas are related to water resources. This is due to the high demand as a result of population activities on the coast beside the water quality on the coast is less good than that onthe mainland. The objective of this study is to review and compare the selection of clean water supply methods and their alternatives, especially in Hong Kong and Jakarta, from a public policy point of view. Hong Kong has a variety of water supply methods. Currently, the ones that are still used are seawater toilet flushing and water imports from China. In policy formation, Hong Kong has not looked at it holistically or is still traditional. In Indonesia, water resources are the obligation of the state to meet the needs of its population in accordance with the 1 945 Constitution. Jakarta\u27s coastal areas have not fully experienced access to piped water to date, so the Provincial Government has chosen the method of providing water according to public acceptance

Sepanjang aliran sungai segmen Kecamatan Sumbersari dan Kecamatan Kaliwates ini terdapat aktivitas antropogenik berupa perumahan padat penduduk dan lahan pertanian yang menghasilkan limbah organik maupun an-organik. Kegiatan tersebut yang berhubungan langsung ke sungai berpotensi menambah beban pencemaran. Beban pencemaran yang dihasilkan dapat berpotensi menurunkan kualitas air. Tujuan penelitian ini yaitu menganalisis kualitas air dan laju deoksigenasi serta reoksigenasi Sungai Bedadung Segmen Kecamatan Sumbersari-Kaliwates menggunakan metode Streeter-Phelps. Pengambilan data berupa debit air, TSS, DO, BOD, dan COD dengan grab sampling. Hasil perhitungan laju deoksigenasi dan reoksigenasi disintesis dengan metode deskriptif kuantitatif. Nilai TSS dan DO memenuhi baku mutu kelas I akan tetapi nilai BOD dan COD tidak memenuhi baku mutu kelas I. Nilai rata – rata laju deoksigenasi (rD) dan reoksigenasi (rR) secara berurutan sebesar 0,798 mg/L.hari dan 2,753 mg/L.hari. Nilai laju reoksigenasi lebih besar dari pada nilai laju deoksigenasi. Kondisi tersebut mengindikasikan bahwa kemampuan Sungai Bedadung berjalan dengan baik dalam reduksi bahan organik secara alami. Besar kecilnya rR dan rD dipengaruhi oleh konstanta reoksigenasi, konstanta deoksigenasi, dan profil hidraulik sungai.Bedadung River is one of the main rivers in Jember Regency. Along with the river flow of the Sumbersari Subdistrict and Kaliwates Subdistricts, there is an anthropogenic activity in the form of densely populated housing and agricultural land that produces organic and inorganic waste. Such activities that are directly related to the river have the potential to increase the burden of pollution. The resulting pollution load can potentially lower water quality. The purpose of this study is to analyze the water quality and the rate of deoxygenation and reoxygenation of the Bedadung River Segment Sumbersari-Kaliwates District using the Streeter-Phelps method. Data collection in the form of water debit, TSS, DO, BOD, and COD with grab sampling. The results of the calculation of the rate of deoxygenation and reoxygenation are synthesized using quantitative descriptive methods. The TSS and DO values meet the grade I quality standard but the BOD and COD values do not meet the grade I quality standard. The mean deoxygenation rate (rD) and reoxygenation (rR) were 0.798 mg/L.day and 2.753 mg/L.day, respectively. The value of the reoxygenation rate is greater than the value of the deoxygenation rate. These conditions indicate that the Bedadung River\u27s ability to perform well in reducing organic matter naturally. The size of rR and rD is influenced by the reoxygenation constant, deoxygenation constant, and the hydraulic profile of the river

The estimation of mammal species loss and gain from shrubs to oil palm plantations in South Sumatera
Get PDFBeberapa penelitian sebelumnya menyebutkan bahwa perubahan tutupan lahan menjadi perkebunan kelapa sawit menyebabkan kehilangan jenis satwaliar, salah satunya dari kelompok mamalia. Oleh karena itu, diperlukan data mengenai bagaimana besarnya kehilangan jenis tersebut. Penelitian ini menduga besaran kehilangan dan perolehan jenis mamalia akibat adanya pembangunan perkebunan kelapa sawit. Data diambil dengan pengamatan langsung (metode strip transect) secara paralel di perkebunan kelapa sawit PT. Rambang Agro Jaya, Sumatera Selatan. Penelitian ini dilakukan pada tutupan lahan antara sebelum (semak belukar) dan setelah adanya perkebunan kelapa sawit. Hasil penelitian ini menunjukkan bahwa perubahan dari semak belukar menjadi perkebunan kelapa sawit tidak mengubah jumlah jenis mamalia, namun meningkatkan indeks kekayaan jenis dan menurunkan indeks kekayaan jenisnya. Indeks kesamaan jenis antara semak belukar dan perkebunan kelapa sawit adalah 0,56. Pembangunan perkebunan kelapa sawit juga menyebabkan kehilangan dan perolehan jenis mamalia dengan persentase yang sama, yaitu 67%. Keberadaan mamalia setelah adanya perkebunan kelapa sawit diduga disebabkan karena ketersediaan pakannya.Several previous studies stated that land cover changes to oil palm plantations caused the loss of wildlife species, one of which was from the mammals. Therefore, data on the magnitude of this type of loss is needed. This study estimates the amount of loss and gain of mammal species due to the development of oil palm plantations. Data were taken by direct observation (strip transect method) in parallel at the oil palm plantation of PT. Rambang Agro Jaya, South Sumatra. This research was conducted on the land cover before (shrubs) and after the development of oil palm plantations. The study shows that the change from shrubs to oil palm plantations does not change the number of mammal species but increases the species richness index and decreases the species richness index. The similarity index of shrubs and oil palm plantation is 0.56. The development of oil palm plantations also causes the loss and gain of mammal species with the same percentage of 67%. The presence of mammals in oil palm plantation is thought to be due to the feed availability
