Abstract

Abstract: This study using an interview for survey, respondents were asked a series of questions about their willingness to pay for environmental services as hypothetical research, which would assist in the conservation of water resources. Willingness to pay (WTP) for the owners who commercialized the well water using bidding game methods with offers of different starting points was asked to the respondents for the Groundwater Basin (CAT) Tabun-Bakunase-Haukoto-Sikumana, CAT Kupang-Oesapa-Tarus, CAT Penfui and Baumata, CAT Bolok-Tenau-Alak-Namosain. The results of the study showed that the value of Willingnes To Pay of the well owner was commercialized from 17 respondents who were willing to pay in the amount of Rp. 518.209 or Rp.6,100/m3. The average cost of production around Rp. 146.650/day, with the amount of discharged water that taken is 4.175 m3, with a cost per 5 m3 is Rp. 3.482, resulting in Rp.30.997 surplus for the producer. Consumer Respondent surplus towards payment of environmental services for commercialized wells water resources is Rp. 496.000,. The consumption of commercialized well water resources in Kupang on CAT Bolok-Tenau-Alak-Namosain is 150 m3/day or 54.750 m3/year, CAT Tabun-Bakunase-Haukoto-Sikumana is 2.600 m3/day or 949.000 m3/year, CAT Kupang- Oesapa-Tarus is 1.125 m3/day or 410.625 m3/year, CAT Penfui is 300 m3/day or 109.500 m3/year, and the amount of water withdrawal is less than the potential of groundwater in each CAT, so there is a surplus of water discharge that taken on CAT in the city of Kupang. The factors that influence the agreed response based on the test results indicate that the risk factors that have a low level of risk are Age (X1), Education (X2), Occupation (X3), Cost (X5), while risk factors that have a strong level of risk are Acceptance (X4) and Environmental Services Knowledge (X6). For Age risk factors (X1), Education (X2), Employment (X3), Costs (X5) have a low level risk level, this means that these factors are not risk factors that can pose a high risk on the willingness of the respondents to pay (WTP). While Acceptance (X4) and Environmental Services Knowledge (X6) have strong risk factors which means that these factors pose a strong risk to the willingness of respondents to pay (WTP), so that a significant effect is partially between acceptance and knowledge of environmental services to willingness of well owners in paying for groundwater environmental services that are used as economic goods. Acceptance and knowledge of environmental services have a significant effect because the greater the acceptance and knowledge of environmental services, the greater the willingness to pay for environmental services.

Abstract

Respirasi tanah terdiri atas respirasi autotrof dan heterotrof. Pada lahan gambut, respirasi heterotrof setara dengan laju dekomposisi bahan gambut. Penelitian ini bertujuan mengembangkan model potensial redoks (Eh) tanah sebagai penduga respirasi heterotrof dari perkebunan kelapa sawit pada lahan gambut tropika. Respirasi tanah diukur menggunakan metode sungkup tertutup pada plot close-to-tree (berjarak 2 m dari pohon) dan far-from-tree (4.5 m dari pohon), sedangkan untuk respirasi heterotrof pada plot root-cut (4.5m dari pohon) yang disiapkan dengan pemotongan akar hingga kedalaman 80 cm dan diinkubasi selama 8 bulan. Respirasi tanah pada lokasi penelitian 40.81 ton CO2 ha-1.th-1, 50.53% darinya berasal dari respirasi komponen heterotrof (RKH). Respirasi heterotrof berkorelasi positif dengan Eh tanah pada pH 7 di kedalaman -30 dan -90 cm (Eh7~30 and Eh7~90) dan berkorelasi negatif dengan tinggi muka air tanah. Nilai koefisien korelasi linier sederhana yang signifikan, r= 0.84 dan 0.87; n= 12, dengan RKH masing-masing ditunjukkan oleh Eh7~30 and Eh7~90. Oleh sebab itu, kedua faktor tersebut dapat disarankan sebagai penduga RKH dengan persamaan: RKH (ton CO2 ha-1.th-1) = 18.2 + 0.029 Eh7~30 + 0.037 Eh7~90 (Eh dalam mV).

Abstract

Protected forests play an important role in supporting human life, protecting land and water and preventing the dangers of flooding and landslides, but a lot of conversions have taken place today. Research-based on techniques for observation, interviews, and case studies. Measurement of respondents' perceptions and attitudes is carried out using instruments in the form of questionnaires that refer to the Likert scale. Data analysis was performed descriptively to describe the level of perception, attitude with simple non parametric linear regression. Maruni protected forest has the potential of limestone with 11 mineral elements, 5 of which are the largest Ca (93.62%), Si (2.45%), Mg (1.58%), Al (0.97%) ) and K (0.47%). This forest allows conversion area, from an area of ​​969.84 ha with limestone potential of only 250 ha (25.78%), another 719.84 ha (74.22%) can still be designated as a protected forest. The public perception of conversion to cement mining was 59.03% negative, 14.83% neutral and 26.12% positive. While the attitudes of the community 43.1% accept, 38.94% neutral and 47.92% reject the conversion to become cement mining. The community hopes that there will be economic improvement, community empowerment and employment, especially affected communities.

Abstract

Nowadays, electricity is a basic human need that must be available. Therefore, efforts to obtain electrical energy from renewable natural resources continue to be explored, especially water energy from watersheds and sub-watersheds. Aceh Province is a relatively widely available area of ​​watersheds and sub-watersheds. This study aims to analyze and categorize the potential of electric power generated by the Lawe Sempali sub-watershed, Aceh province, as a source of hydroelectric power. The method used in this research is the study of literature and field studies. The rainfall analysis of the ten year return period plan was carried out with four approaches, namely (i) normal distribution method (ii) normal log distribution method, (iii) Gumbel distribution method, and (iv) Pearson III log distribution method. Discharge plans that occur are analyzed using the rational method. The categorization of the power capacity of hydroelectric power plants is based on the capacity that can be produced by the sub-watershed. The results of this study were to report that the Lawe Sempali Sub-watershed has the potential to be a source of hydroelectric power generation in the category of micro-hydro and or small-hydro power plants. The capacity of electric power generated with planned discharge in the shortest return period (2 years) is a minimum of 68.21 KW (head 2 m) and a maximum of 3.41 MW (head 100 m).

Abstract

Perubahan penggunaan lahan hutan menjadi perkebunan kelapa sawit diduga mengubah distribusi fraksi fosfor (P) tanah. Penelitian ini bertujuan untuk mengevaluasi fraksi P pada lapisan permukaan tanah di lahan hutan dan perkebunan kelapa sawit di Jambi, serta korelasinya dengan sifat kimia tanah. Sampel tanah diambil dari lapisan atas tanah hutan dan perkebunan kelapa sawit. Beberapa sifat kimia tanah dan fraksi-fraksi P dianalisis. Fraksionasi P dilakukan dengan menggunakan metode Tiessen dan Moir. Hasil penelitian menunjukkan bahwa fraksi P agak labil yaitu NaOH-Porganik (-Po ) dan -Pinorganik (Pi) merupakan fraksi yang ditemukan dominan di hutan dan perkebunan kelapa sawit. Persentase P labil (resin-Pi, NaHCO3-Pi,-Po) dan P organik agak labil (NaOH-Po) dari total fraksi P ditemukan lebih tinggi di lahan hutan dibandingkan dengan perkebunan kelapa sawit. Fraksi NaOH-Pi di perkebunan kelapa sawit lebih tinggi nilainya dibandingkan dengan di hutan. Hal ini menunjukkan bahwa secara alami perubahan penggunaan lahan hutan menjadi kelapa sawit mengubah distribusi fraksi P sebagai akibat dari perubahan kandungan karbon (C) organik tanah. Analisis korelasi menunjukkan bahwa hampir semua fraksi P berkorelasi positif dengan C organik, mengidentifikasikan bahwa mineralisasi C organik mempengaruhi distribusi fraksi P yang artinya C organik tanah mengontrol distribusi fraksi P pada lapisan permukaan tanah di lahan hutan dan perkebunan kelapa sawit.
