Abstract

The study aimed to identify the total volume of clean water consumption and total economic value of hydrological services used for domestic and agricultura needs. The research was carried out in Lakomea Village, Landono District of South Konawe Regency since May to June 2015. The study employeed survey and depth interview with key respondents.  Location of the study was determined using Purposive Sampling Method. While respondents were identified in the two stages : (1) Respondents are grouped in the two major gorups using Stratified Sampling Method namely: (a) Domestic water user group; and (b) Irrigation water consumers group. (2) Respondents for the domestic water users were then determined using Simple Random Sampling, whereas for irrigation water consumersusing Sensus Sampling Method with consideration that the number of users of irrigation water were only 3 families. Data analysis was conducted using Hedonic Price for water domestic used and Productivity Method for the agricultural used.The results of the research showed that the total volume of water usage over the past year using by135 families obtained 27.504 m3/year. While the economic value of this domestic waterused reached Rp. 16.197.930,72/year.  The research also revealed that the economic irrigation water for rice fields achieved Rp. 1.811.950,00/Planting Season. In conclusion, Total Economic Value of the hydrological environmental services of Lakomea Productive Forest Area of Landono District, South Konawe Regencyobtained Rp. 18.009.880,72/year.Keywords: Valuation, Environmental Services, Domestic Use of Water, Agricultural Use of Water, Total Economic Value

Abstract

Forest hydrological environmental service such as water resource was one of the most important environmental services produced by forest. The objective of this study is factors affected the society in determining the analyz economic valueof forest hydrological environmental service. This research used Willingness to Pay (WTP) method as appreciation of Laroonaha community village to the hydrological environmental services of productive forest area surrounding. Besides, Multiple Regressions method used to determine the main factor influenced the community in deciding the economic value.The result of this research showed that the total of water consumption yielding from productive forest area of Loi-loiyo Mountain by the Laroonaha society is 1.039,5 m3/month with an average usage about 14,4375 m3/KK/month or about 12.474 m3/year with an average usage of 173,25 m3/KK/year.The value of total WTP hydrological environmental services for the Laroonaha society was about Rp. 6.543.652/monthwith an average value of WTP about Rp. 6.295/KK/month. The main factor affected the respondents WTP value was the average of the respondent family income to determine on the confidence level of 99%, whereas the number of family member and the educational level was not significantly affected, with standard error 20% and 5%. Keywords: EconomicValuation, Hydrological Environmental Service,Willingness to Pay.

Abstract

Penelitian ini bertujuan untuk menaksir potensi kayu berupa jumlah, luas bidang dasar, dan volume kayu berdasarkan tingkat pertumbuhan pohon. Kemudian mengetahui  struktur tegakannya secara vertikal.  Selain itu, akan diketahui berbagai manfaat dari pohon yang ditanam serta pola tanam yang dikembangkan pada hutan rakyat di Kecamatan Barangka.  Pengambilan sampel pohon dilakukan secara acak tanpa pemulihan (sampling without replacement) pada lahan hutan rakyat dengan bentuk bujur sangkar dan kesalahan yang diperkenankan (allowable error)  5%.   Hasil penelitian menunjukkan bahwa 1) Potensi kayu sebagai berikut : a) jumlah batang yakni kelas tree (pohon) berjumlah 159 batang/ha, kelas pole (tiang) 2119 batang/ha, kelas sapling (pancang) 497 batang/ha; c) luas bidang dasar berupa kelas tree (pohon) berjumlah 6,794 m2/ha, kelas pole (tiang) 14,241 m2/ha, kelas sapling (pancang) 2,545 m2/ha; d) volume kayu pohon yakni kelas tree (pohon) berjumlah 118,69 m3/ha, kelas pole (tiang) 174,575 m3/ha, kelas sapling (pancang) 10,676 m3/ha. 2) Struktur tegakan secara vertikal yakni lapisan atas > 16,21 m berjumlah 697 batang/ha, lapisan tengah 14,59 – 16,21 m berjumlah 976 batang/ha, dan lapisan bawah < 14,59 m berjumlah 1116 batang/ha. 3) Kategori manfaat pohon yang ditanam yaitu kategori manfaat kayu : jati; kategori manfaat kayu dan buah : jeruk dan rambutan; kategori manfaat kayu dan biji : jambu mete dan kakau; kategori manfaat kayu, buah, dan hijaun makanan ternak (HMT) : nangka. 4) Pola hutan rakyat yaitu Pola I : jati, jagung, ubi kayu dan rumput; Pola II : jati dan kacang panjang, tomat dan labu; Pola III : jati, jambu mete, kakau, dan kelapa; Pola V : jati, rambutan, jeruk, nangka, dan pisang; Pola VI : jati. Kata kunci : hutan rakyat, potensi kayu, struktur, manfaat pohon, pola

Abstract

Water is part of the environment has an important function for human life and other living things. The level of water pollution has increased significantly followed by an increase in population. Water pollution is caused by several things, one of which is detergent waste. This study aims to determine the concentration of detergents as well as the load capacity of sanua river water detergent pollutants, in Sanua Village, West Kendari District, Kendari City.The results showed that the type of detergent used by the public was powder detergent which contained LAS (Linear Alkylbenzene Sulfonate) compounds. Detergent concentration analysis results showed that, detergent concentration in February, station 1 was 0.067µg l -1, station 2 was 0.106µg l-1, station 3 was 0.117µg l-1, station 4 was 0.129µg-1, station 5 was 0.112 μg-1 and station 6 were 0.109 μg l-1. Whereas in March station 1 was 0.128µg-1, station 2 was 0.496µg l -1, station 3 was 0.139µg l-1, station 4 was 0.107µgl-1, station 5 was 0.265µg l-1 and station 6 was 0.149µg l-1 1 The average concentration of the pollution load capacity of detergents is 0.106 µg-1 in February and 0.215 µg l-1 in March, this value is far from the quality standard stipulated by PP. No. 82 of 2001, where the quality standard is 200 µg l-1 for grades 1-3.

Abstract

The purpose of this study was to determine the Water Pollution Index of the Jompi River in Muna Regency as Raw Water for PDAM Kota Raha. This research was carried out in April to May 2018, using the Pollution Index Analysis method carried out with reference to the Regulation of the Minister of Environment No. 115 of 2003 concerning Guidelines on the Status of Water Quality. with physical parameters (odor, color, turbidity, taste, dissolved solids (TDS) and suspended solids (TSS)), organic chemical parameters (oil and fat, surfactants / detergents), biological parameters (total Coliform and number of Escherichia coli) . Still in the classification meets quality standards. While the average percentage of the River Jompi Pollution Index has a classification of ≤1, which means that the River Jompi is still in good condition.
