Abstract : Ibn Khaldun is one of the leaders of Islamic thinkers who has a great influence in the development of science. Ibn Khaldun is better known as a historian and social expert. As stated in his Muqoddimah work, besides having the concept of education in an educational perspective is the result of the ideas of Ibn Khaldun who emphasized education. Ibn Khaldun's view of education rests on concepts and philosophical-empirical approaches. Through this approach, he provides direction to the vision of the ideal and practical goals of Islamic education. Based on the results of research from the literature that has been done that Ibn Khaldun is a great figure in the Islamic world, who succeeded in contributing so much in the scientific world that exists in the world. The thoughts of Ibn Khaldun cannot be separated from the roots of Islamic thought. Ibn Khaldun considers that education is the essence of human existence. Ibn Khaldun argues that education seeks to give birth to a cultured society and strives to preserve the future existence of society. Ibn Khaldun's view of education rests on concepts and philosophical-empirical approaches. Through this approach, he provides direction to the vision of the ideal and practical goals of Islamic education. The challenge of education according to Ibn Khaldun is that education can create quality human resources, namely giving birth to a culture of society and trying to preserve and increase the existence of the next society.Keywords: Education, Ibnu Khaldun, Perspective

Abstract

Effort to Increase Oil Palm Production through Application Technique of Soil and Water Conservation (K. Murtilaksono, W. Darmosarkoro, E.S. Sutarta, H. H. Siregar, and Y. Hidayat): The study was carried out at block 375, 415, and 414 (block 1, 2, and 3) Afdeling III, Mangement Unit of Rejosari, PT Perkebunan Nusantara VII, Lampung from June 2005 until December 2007.  Objective of the study is to examine the effect of soil and water conservation measurement, namely bund terrace and silt pit that are combined with retarded-water hole on production of oil palm. Sampled trees of each block were randomly selected as much as 36 trees.  Parameters of vegetative growth (additional new frond, total of frond, number of new bunch), production (number of bunch, fresh fruit bunch (TBS)), and average of bunch weigh (RBT) were observed and recorded every two weeks.  Production of palm oil of each block was also recorded every harvesting schedule of Afdeling.  Tabular data were analyzed descriptively by logical comparison among the blocks as result of application of bund terrace and silt pit.  Although the data of sampled trees were erratic, bund terrace and silt pit generally increasing number of frond, number of bunch, average of bunch weight, and fresh fruit bunch.  Bund terrace gived the highest production of TBS (25.2 t ha-1) compared to silt pit application (23.6 t ha-1), and it has better effect on TBS than block control (20.8 t ha-1).  Aside from that, RBT is the highest (21 kg) at bund terrace block compared to silt pit block (20 kg) and control block (19 kg).

Abstract

The study was aimed to quantify volume of surface runoff, soil erosion and nutrient loss from the forest-agriculture landscape (forest margins) in Lore Lindu National Park Central Sulawesi.  Surface runoff volume and soil erosion were measured daily on erosion plots. It was installed on  several land use types i.e. forest land,  maize,  young cocoa, medium cocoa, old cocoa, vanilla, shrub and bush and bareland, on the soil Typic Dystrudepts with slope ± 40%. The nutrient content in surface runoff and sediments were analyzed from selected surface runoff and sediment samples.  Surface runoff and soil erosion from agriculture land were respectively 2.1 to 3.4 and  3.6 to 5.8 times higher than from forest lands. Meanwhile, surface runoff and soil erosion from bareland were respectively 7.0 and 23.7 times greater than forest land respectively.  Sediment nutrient contents from forest land were  higher than agriculture land.  In the contrary, total nutrient lost from agriculture land were higher than forest land ones.  Nutrient losses carried by surface runoff were larger than those losses carried by sediments.  Dissolved organic carbon (DOC) loss in surface runoff was 6,1 to 8,0 times higher than total organic carbon (TOC) loss in sediments.  Likewise, nitrate (NO3-) loss in surface runoff was 1.9 to 12.1 times higher than total nitrogen (TN) in sediments as well as potassium, calcium, magnesium and sodium losses.  Potassium is dominant cation loss carried by the surface runoff, while calcium is mainly carried by sediment.Keywords:  Dissolve organic carbon; forest-agriculture landscape; nutrient loss; soil erosion; surface runoff[How to Cite: Hidayat Y, K Murtilaksono and N Sinukaban. 2012.

Abstract

Crop and management factor value is significantly corelated with outputs of ANSWERS model especially on soil erosion.   Using daily crop and management factors (daily C factors), the ANSWERS model performs well in predicting soil erosion which is showed by determination coeffient (R2 = 0.89), model efficiency (0.86), and average of percentage model deviations (24.1 %).  Whereas using USLE C factor (2 cropping systems), predicted is much higher than measured soil erosion (over estimate).  Output of the model is not statisfy, it is represented by model coefficient (0.40) and average of percentage model deviations (63.6 %).

Abstract

The purpose of this experiment was to investigate the influence of soil compaction and water content on root development of 6 month old sengon seedling. The experiment was arranged 3 x 3 factorial experiment within a complete randomized design and 3 replications. The factor number one was soil compaction and factor number two was soil water content. The soil compaction factor consists of 3 levels, which are 1,5 g/cm3 (A1), 1,2 g/cm3 (A2), and 0,9 g/cm3 (A3) respectively, while the soil water content also consists of 3 levels, which are 60,41 % (B1), 49,64% (B2), and 42,86 % (B3) for each level. The parameters were counted which are root number, diameter, root length, biomass, surface area, and root length density. The result was that soil compaction treatment has a significant influence to root number, root length, biomass, surface area, and root length density. On the other hand the soil water content treatment on pF 2,54 until 3,5 and interaction soil compaction and water content have no influence to root number, diameter, root length, biomass, surface area, and root length density. Root number, diameter, length, biomass, surface area and root length density were increased accordingly to the age of the seedling, but the increasing of soil compaction has decreased to the number, length, root length, biomass, surface area and root length density. The secondary root was found more larger than the primary and the tertiary root in term of the root length, surface area and root length density.

Abstract

Banjir di Cekungan Bandung terjadi setiap tahun di wilayah cekungan terendah seperti di Kecamatan Majalaya, Ciparay, Deyeuhkolot, Rancaekek, Bojongsoang, dan Baleendah, Kab. Bandung. Kajian analisis bahaya dan arahan mitigasi banjir merupakan salah satu upaya untuk mengurangi risiko dari bencana tersebut. Tulisan ini bertujuan untuk menganalisis bahaya dan menyusun arahan mitigasi banjir di wilayah Cekungan Bandung. Bahaya banjir diidentifikasi dengan menganalisis daerah bahaya banjir menggunakan Modification Topography Wetness Index (MTWI), sedangkan arahan mitigasi banjir dianalisis secara deskriptif dengan membandingkan hasil analisis bahaya dengan data penggunaan lahan. Hasil penelitian menunjukkan bahwa 2.36% daerah Cekungan Bandung termasuk kelas bahaya tinggi, 7.15% termasuk bahaya sedang, dan 90.49% termasuk daerah bahaya rendah. Kesadaran masyarakat terhadap pengelolaan lingkungan yang rendah juga menjadi salah satu faktor penyebab banjir di Cekungan Bandung. Pada zona prioritas arahan mitigasi banjir dilakukan dengan pembuatan saluran drainase tambahan untuk mengalirkan air dari cekungan terendah. Selain itu, perlu dilakukan pengendalian penggunaan lahan dengan cara penegakan hukum terhadap penggunaan lahan yang tidak sesuai Rencana Tata Ruang Wilayah (RTRW) dan dilakukan rehabilitasi hutan dan lahan pada lahan kritis di DAS Citarum Hulu.

Abstract

Banjir yang terjadi hampir setiap tahun di Daerah Aliran Sungai (DAS) Ciujung menyebabkan DAS ini menjadi sorotan berbagai pihak. Penelitian ini bertujuan untuk mengkaji kinerja model SWAT untuk memprediksi debit aliran dan hasil sedimen DAS Ciujung, serta mensimulasikan parameter hidrologi untuk menurunkan debit aliran dan hasil sedimen DAS Ciujung. Dalam menjalankan model SWAT terdapat beberapa tahapan kegiatan yang dilakukan yaitu: (1) deliniasi batas DAS Ciujung, (2) pembentukan HRU, (3) pendefinisian HRU, (4) input data iklim, (5) membangun input data, (6) menjalankan model SWAT, (7) kalibrasi dan validasi model, dan (8) simulasi parameter hidrologi. Model SWAT cukup baik untuk mensimulasikan debit aliran DAS Ciujung. Hal ini dapat dilihat dari hasil kalibrasi model SWAT untuk memprediksi debit aliran yang menunjukkan nilai R2 dan NSE masing-masing sebesar 0.83 dan 0.65 (baik) serta hasil validasi model masing-masing 0.78 dan 0.63 (memuaskan). Hasil sebaliknya diperlihatkan dalam memprediksi hasil sedimen DAS Ciujung dengan nilai R2 dan NSE yang dihasilkan masing-masing sebesar 0.55 dan -193.62 (tidak memuaskan). Skenario pengelolaan lahan yang diterapkan diantaranya adalah fungsi kawasan hutan, rehabilitasi lahan kritis, teknik KTA metode vegetatif dan sipil teknis, serta skenario gabungan. Berdasarkan kemampuannya dalam menurunkan aliran permukaan, hasil sedimen, dan hasil air (water yield) serta meningkatkan aliran dasar dan aliran lateral, penerapan tindakan pengelolaan lahan gabungan merupakan pengelolaan lahan yang harus dilakukan.

Abstract

Indigofera zollingeriana is a bush type legume plant that grows well in full light but tolerant to shade conditions. Modification efforts of the environment with paranet shade treatment are the accurate approach. The objective of this research was to study the tolerance limit of I. zollingeriana plant at various shade levels. The study was conducted in October 2016-April 2017 at the Leuwikopo-IPB Bogor and used randomized block design with one shade factor (0, 40, 65, and 80%). The results of the measurement of microclimate with various shading levels showed that in the shade treatment 40%, the intensity of light decreased by 40% the temperature decreased by 6%, while the humidity increased by 10%. In the 65% shade, the light intensity decreased by 62%, the temperature decreased by 10%, while the humidity increased by 24%. In the 80% shade, the light intensity decreases 95%, the temperature decreases 13%, while the humidity increases 34%. The shade intensity has a real significant on decreasing stem diameter, number of branches, canopy dry weight, and roots. I. zollingeriana is rather tolerant of shade and it is able to adapt to shade up to 40%.

Abstract

Poverty in rural areas is a central issue of national mitigation which can?t be postponed and should be a priority in the implementation of social welfare development. Lack of access to capital sources, markets and technologies, as well as farmer?s organizations are still weak to be one of our problem. Optimizing the potential of existing financial institutions could be an alternative source of funding for farmers and rural communities, namely the development of MFIs. To that end, this paper aims to identify the problems of MFIs, to analyzes the potential of MFI?s which can use as basis for the future development strategy and key success factors of empowerment MFI. From the discussion, MFIs development can be the one of effective solution in reducing poverty with the help of the role and intervention of various parties, both governmental, non-governmental and community. This can seen from the success of the empowerment of MFIs that have been implemented in Bangladesh, Philipine and China. Keywords: MFI, Poverty, Rural.
