Abstract

The organic matter in the forest ecosystem that contributes to the organic horizon of soil profile decomposes to CO2. The DOC (dissolved organic carbon) leached to the mineral soil horizons could be decomposed, leached or adsorbed onto mineral surfaces. The effect of soil properties on the DOC dynamic has not been fully understood because of limited data. The objective of this research was to characterize the DOC in Bukit Duabelas National Park and reveal the effect of soil profile position in toposequence and soil properties to the DOC. Six soil profiles were made with different positions in toposequence (two soil profiles on each upper, middle, and lower slope). Lysimeters were installed horizontally (in AO, AB and B horizons and in each soil profile) and connected to a bottle collector that placed on the bottom of the soil profile. The soil samples were collected from each of the soil profiles, at the beginning of the research, while soil solutions were collected periodically. The results showed that the independent sample t-test revealed that fluxes of DOC of soil profile on the lower slope were different from that of soil profiles on the upper and middle slopes. The concentration, amount, and fluxes of DOC in soil profile on the lower slope were higher than those of soil profiles on the upper and the middle slopes. The independent sample t-test also revealed that fluxes of DOC of AO horizons were different from those of AB and B horizons. The concentration, amount, and fluxes of DOC of AO horizon were higher than those of AB and B horizons. The result of Pearson correlation showed positive correlations between DOC fluxes with organic-C, total-N, and Cation Exchange Capacity (CEC), but negative correlation with soil bulk density, pH, and Fe dithionite-citrate-bicarbonate (Fed) content. The results suggested that soil profile on the lower slopes on toposequence had a higher amount of DOC than that on other soil profiles above it. Horizon AO had a higher amount of DOC than that of AB and B horizons. The increase of organic-C, total N and CEC increased DOC. On the other hand the increase of soil bulk density, pH and Fed decreased DOC. Keywords: DOC, horizon, soil organic matter, toposequence

Abstract

Watershed (river basin) is a hydrological unit. DAS holds water, distributes water through a channel system from upstream to downstream, and ends in a body of water in the form of a lake or sea. Watershed is also an ecosystem, where the elements of organisms and the biophysical environment and chemical elements interact dynamically and in which there is a balance. DAS is seen as a unit of territorial unity where rainwater collects into a river to become a river flow. The factors that influence the characteristics of the watershed are morphometric factors and the biophysical aspects of the watershed. Watershed morphometry is a quantitative measure of the natural characteristics of the watershed, namely the geomorphological aspects of an area. This characteristic is related to the process of draining (drainage) of rainwater that falls in the watershed including the shape of the watershed, the area of the watershed, the density of the river (drainage), and the flow pattern. River flow is greatly influenced by the biophysical conditions of the Kambang watershed. Analysis of the biophysical conditions of the Kambang watershed includes analysis of soil types, land use, topographic conditions including slopes and contours, as well as the quality of Kambang river water. Considering the strategic designation of the Kambang watershed should be aligned with the watershed character.

Abstract

The character of caring for the environment is an important part of the effort to create a sustainable environment so it needs to be passed on to the next generation. Schools are a means of internalizing important values in shaping the character of caring for the environment in the younger generation, especially students. The process of internalizing the character of caring for the environment is currently still focused on subjects in schools that are related to the environment. Therefore, schools have an important role in implementing the internalization of environmental care characters. One of the implementations of the environmental care character is to carry out 6R-based waste management, namely reducing, reusing, replacing, separating, recycling, and composting. The purpose of this activity is to increase students' awareness of the environment (environmental care character) and increase students' insight and skills in managing waste in the school environment. This activity was carried out for 6 months. This activity is carried out on a bottom-up basis using methods of counseling, mentoring, training, and evaluation. This activity consists of six stages of activities: (1) socialization of environmental care character and school waste management; (2) Demonstration of garbage selection; (3) demonstration of composting; (4) Compost monitoring assistance; (5) Compost harvesting; and (6) Evaluation of activities. The result of this activity is that participants understand the character of caring for the environment, implementing waste management, separating waste, and making compost.

The objectives of this research are to know effect of forest conversion to land of rubber (Hevea brasiliensis) and palm oil (Elaeis guinensis Jack) farming on run off and soil erosion and different of erosion rate on agro technology of rubber and palm oil farming in Batang Pelepat watershed. The research was carried out during 3 months, begin October to December 2006. Run off and soil erosion measured plot with gutter in the lower of plot. Experimental design for this research is randomized complete block design, with land use type as treatment and slope class as replication or block. Data analyzed statistically by variance analysis (F-test) and Duncan New Multiple Range Test on confidence 95% (α = 0.05). The results of this research show that area of forest coverage in Batang Pelepat watershed was decreasing. In 1986 this area still 94,50% of watershed area, but in 1994 area of forest only 78,17% and in 2006 forest area 64,20% of watershed area. Forest conversion was carried out to land of rubber and palm oil farming with some actual agro technologies. Land of monoculture rubber I resulted the highest run off and soil erosion more than the other land use type and showed different of run off and soil erosion on land of secondary forest.

Abstract

Pembangunan Kota Jambi menyebabkan DAS Kambang dimanfaatkan untuk berbagai macam peruntukan. Selain sebagai pusat ibu kota, wilayah yang masuk dalam DAS Kambang juga merupakan pusat pendidikan, ekonomi, dan keagamaan. Ditemukan fenomena banjir di beberapa bagian wilayah Kota Jambi, saat terjadi hujan. Tata ruang Kota Jambi telah mengatur pengelolaan sistem drainase, walaupun belum ada kepastian implementasi yang berwawasan lingkungan. Peraturan Daerah Kota Jambi No 9 Tahun 2013 Tentang Rencana Tata Ruang Wilayah Kota Jambi Tahun 2013 disebutkan bahwa lokasi atau daerah rawan genangan dan banjir di Kota Jambi salah satunya adalah wilayah yang dicakupi oleh DAS Kambang, antara lain Kecamatan Telanaipura dan Kecamatan Kota Baru. Penelitian ini bertujuan menggambarkan kondisi aktual drainase di DAS Kambang dan penataan sistem drainase DAS Kambang yang berwawasan lingkungan sesuai dengan tata ruang Kota Jambi. Hasil penelitian di lapangan, menunjukkan kondisi saluran drainase eksisting yang telah berubah fungsi. Analisa perhitungan kapasitas debit eksisting tidak mampu menampung debit rencana dengan parameter perhitungan curah hujan rencana Metode Log Person III. Penerapan sistem drainase konvensional pada DAS Kambang yang mengalirkan air  secepatnya ke badan air terdekat perlu diubah menjadi sistem drainase berwawasan lingkungan yang berprinsip menampung dan meresapkan kelebihan air.

Abstract

Jl. Pancasila Pondok Tinggi District is one of the districts in Sungai Penuh city which often experiences inundation during the rainy season. In this area, the performance of the drainage system is determined by the involvement of the community. Apart from that due to the lack of government operation and maintenance costs, the drainage system is mostly managed with community participation. Therefore drainage conditions need to be considered, evaluated with a sustainable drainage system based on community participation. This research was conducted to analyze the performance level of the drainage network on Jl. Pancasila Pondok Tinggi District Sungai Penuh city, the assessment parameters include physical condition, participation and institutional conditions (in this case the community at the research location and related institutions). This research is quantitative descriptive. Data collection was carried out by distributing questionnaires to 42 respondents, interviews with questionnaires and direct surveys to the research location to collect primary data on the physical condition of the drainage network on Jl Pancasila. Data analysis was carried out by providing an assessment of the physical conditions in the field based on direct observations. Data were analyzed using the Partial Least Square (PLS) approach, using the Smart PLS 3.0 software. PLS is a variant-based Structural Equation Modeling (SEM) statistical method. The results showed that the relationship coefficient between physical aspects of the variable on the sustainability of urban drainage had a positive and significant effect, the influence of social aspects on the sustainability of drainage in total had a positive and significant effect and the institutional aspects had a positive and insignificant effect on the sustainability of urban drainage.
