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.

Abstract

Land as a limited natural resource can suffer damage and decrease productivity if it is not managed wisely. Land use of anarea affects the hydrology of the area, changing land use means changing the type and proportion of land cover which in turn affects its hydrological response. Incompatibility of land use can have an impact on decreasing land quality, so that it often resultsin floods, droughts, erosion which will reduce land productivity and community welfare. The equipment used in this researchare: (1) Computer with ArcGIS¬ 10.4 software, ArcSWAT version 2012.1_8 Microsoft Office 2013, SWAT Plot for calculating R2and NS values; (2) Global Positioning System (GPS); (3) Digital camera, stationery and external hard disk to store data.Planting with agroforestry patterns and the application of conservation techniques in the Batang Merao Hulu sub-watershedhave an effect on hydrological characteristics, this is indicated by the reduced runoff coefficient value before plantingagrofrestry with the application of conservation techniques from 0.4 to 0.09 and the flow regime coefficient from 48.49 m3/s to 17.18 m3/s. The best land management scenario is to carry out planting with agroforestry patterns and the application of conservation techniques in the form of mound terraces. This agroforestry pattern not only emphasizes the types of woodyplants and MPTs but also prioritizes local local plants which are the prima donna of the people of Kerinci Regency, namelycoffee and cinnamon, so that ecologically, the hydrological function of the watershed is maintained.

Abstract

One material that has the potential to replace cocopeat and peat for planting media is rice husk biochar because it has the ability to increase pH, has a porous structure and is rich in potassium. Currently, Acacia crassicarpa nurseries generally use polybag and polytube containers which often have negative effects on rooting and problems in the planting process in the field. The use of paper bags as an alternative to containers that have a larger volume advantage than polytubes, and can be directly planted in the field requires a more in-depth study. This study aims to examine the optimum dosage of rice husk biochar and container type for the growth of Acacia crassicarpa seedlings in nurseries. This study used a Split Plot design with a factorial pattern, each consisting of 3 main plots, namely polybag, polytube and paperbag and 4 subplots consisting of 4 doses of husk charcoal biochar, respectively 0%, 10%, 30% and 50 %. Each treatment was repeated 3 times. The variables measured were media porosity, media pH, plant height, stem diameter and seedling root volume. Data were analyzed using the ANOVA test and then tested further with the DNMRT test at α5%. Analysis using SPSS software version 2.3. The results indicated that the interaction between the type of container and the dosage of rice husk biochar only had a significant effect on the porosity variable. The type of container alone did not show a significant effect on soil pH variables, but had a significant effect on plant height, stem diameter and root volume variables. Polybags give the best results for the height and diameter of the seedlings. Polytube gave the best effect on root volume variables, paperbags showed the least circular roots. This variable was not tested but visually shows a significant difference. Treatment of single doses of biochar had a significant effect on soil pH, seedling height, seedling diameter and seedling root volume. There was a tendency to increase soil pH and root volume with increasing doses of biochar. The best seedling height and diameter variables were obtained at a dose of 10% biochar, this gives an indication that the biochar dose is optimum for seedling growth

Abstract There is recently an issue; Batanghari watershed degradation and sustaining Batanghari watershed quality in Jambi Province, Indonesia. Watershed degradation and sustaining watershed quality as well as putting ecological point of view upon watershed management, which in turn emerge in term : integrated watershed management, is also a global issue. We aware of the interdependency between land and soil along with all inherent aspects in them and watershed quality and all inherent aspects in it. It has been proved that unwise measures upon land and soil gives undesired impacts on watershed quality. The first damages shall mostly be upon water quality. For the existence of human being and livelihood of most communities depend strongly on soil and water, at least true to happen in developing and under developed countries, it is true then that both soil and water should be regarded as very important natural resources. By this thought managing and sustaining watersheds need an integrated measures for both components: river, landuse-soil through an ecological approach, conditio sine qua none all efforts will end in failure. The main goal of watershed management are to integrate the use of water, soil, forest and other natural resources within watershed into a NOT CONFLICTING dynamic-ecological based management. This goal can be achieved through an implementation of interdependency concept to regional space planning.   Keywords: watershed, river and interdependency   Abstrak Baru-baru ini ada masalah; Degradasi DAS Batanghari dan  Menjaga Kualitas DAS Batanghari di Provinsi Jambi, Indonesia. Degradasi DAS dan mempertahankan kualitas DAS serta menempatkan sudut pandang ekologi pada pengelolaan DAS, yang pada gilirannya muncul dalam istilah: pengelolaan DAS terpadu, juga merupakan isu global. Kami menyadari adanya saling ketergantungan antara tanah dan tanah beserta segala aspek yang melekat di dalamnya dan kualitas DAS serta segala aspek yang melekat di dalamnya. Terbukti bahwa tindakan yang tidak bijaksana terhadap tanah dan tanah memberikan dampak yang tidak diinginkan pada kualitas DAS. Kerusakan pertama sebagian besar terjadi pada kualitas air. Karena keberadaan manusia dan mata pencaharian sebagian besar masyarakat sangat bergantung pada tanah dan air, setidaknya benar terjadi di negara berkembang dan terbelakang, maka benar bahwa tanah dan air harus dianggap sebagai sumber daya alam yang sangat penting. Dengan pemikiran tersebut pengelolaan dan pelestarian DAS memerlukan langkah-langkah yang terintegrasi dari kedua komponen: sungai, tata guna lahan-tanah melalui pendekatan ekologis, conditio sine qua none semua upaya akan berakhir dengan kegagalan. Tujuan utama pengelolaan DAS adalah mengintegrasikan pemanfaatan air, tanah, hutan dan sumber daya alam lainnya di dalam DAS ke dalam suatu pengelolaan berbasis ekologis dinamis yang TIDAK BERKONFLIK. Tujuan ini dapat dicapai melalui implementasi konsep interdependensi dalam perencanaan ruang wilayah.   Kata kunci: DAS, sungai dan interdependensi
