Abstract

The presence of Islamic education is expected to be an alternative solution to educational problems caused by the materialism education system. This present study aims at investigating education from an Islamic perspective and its role in fostering Islamic personality. This study employed a qualitative approach and literature review method. Based on the results of the discussion, there has been no agreed term on education based on Islamic perspective. However, in this case, the writer is more inclined to ta'dÄb as the term for education in Islam since it, based on its conceptual structure, has included the elements of science (ilm), teaching (ta'lÄ«m), and good care (tarbiyaħ). The purposes of Islamic education are to develop an Islamic personality and to master Islamic safaqah, science and technology, and adequate expertise. In Islam, teachers are regarded as a highly honored person, and students are encouraged to maintain good character and conduct (adab) when they interact with their teachers. In addition, Islamic curriculum and education materials are supposed to be in line with the Islamic Aqeedah (faith). In principle, Islamic education methods have their own characteristics and one of them is the Quranic education method. All media and facilities are permissible as long as it does not conflict with the Islamic Aqeedah (faith). The evaluation in Islamic education consists of measurements and assessments covering the aspects of aqliyah, qolbiyah, and amāliyah. Islamic education plays an important role in fostering Islamic personality since it is inseparable from the idea of Islamic education in order to foster an Islamic personality.

Abstract

Semarang city has experienced of the land subsidence that be caused by intake groundwater in confined aquiferabundant. The land subsidence happened during range of time 20 years, it’s critical boundary so that result theenvironmental damage. Hence needed a study of cause of the land subsidence. This study aim to know theposition of piezometric surface and also explain the mechanism hydrogeology when happened the landsubsidence. The study of spreading aquifer has been done by the analysis of secondary data which is in the formof drilling log data, piezometric surface and soil mechanics test obtained from PLG (Environmental Center ofGeology) Bandung. Later then, between the land subsidence and piezometric surface be overlay becamezonation. From the data made a analysis of cause of the land subsidence. This aquifer has the land subsidence.The land subsidence explainable with the experienced phenomenon fact for example degradation of piezometricsurface at confined aquifer and process of hydrocompaction. That process influenced by two factors that areassess the pore number (e) and specific gravity (Gs). The degradation of piezometric surface formed the trapezeof water table until 20 m from sea level with the mean 0.7 - 1.1 m/year. Hydrocompaction cause the degradationof number of mean pore 0.145 - 0.5 and specific gravity 0.009 - 0.073 . The degradation of piezometric surfaceand process the hydrocompaction cause the fast of land subsidence around 0.5 - 1.75 cm/year.

Abstract

Pemodelan sandbox adalah salah satu jenis pemodelan analog dalam ilmu geologi yang memiliki tujuan utama yaitu simulasi gaya, deformasi dan evolusi struktur cekungan sedimen. Terbentuknya struktur geologi berupa sesar naik (thrust atau backthrust fault) diakibatkan oleh sistem tektonik konvergen dan dapat dimodelkan dengan pemodelan sandbox. Penelitian ini bertujuan untuk memahami mekanisme dan sekuen deformasi dari sistem sesar naik dengan mengetahui hasil deformasi yang berupa pola struktur geologi; mempelajari perkembangan morfologi, pola dan distribusi struktur pada sistem tektonik konvergen; mengetahui variabel pengujian dalam pembentukan deformasi pada pemodelan sandbox. Penelitian dilakukan dari tahap persiapan hingga pelaksanaan. Persiapan yang dilakukan adalah pewarnaan, pengeringan dan pengayakan bahan model yaitu pasir kuarsa Formasi Ngrayong dengan dua macam ukuran butir; kategori ukuran pasir kasar (30-50 mesh) dan kategori ukuran pasir halus (60-80 mesh). Selanjutnya melakukan uji konsistensi alat sandbox. Hingga terakhir menentukan kondisi batas pemodelan seperti ukuran butir, ketebalan dan basement. Pada tahap pelaksanaan, data yang dihasilkan yaitu; foto/ gambar hasil pemodelan, waktu pergerakan dan jumlah sesar yang terbentuk, jarak pemendekan dan perubahan dip sesar, serta perkembangan morfologinya. Struktur yang terbentuk yaitu thrust dan backthrust fault. Morfologi yang terbentuk merupakan sabuk sesar thrust yang perkembangannya ditandai oleh terbentuknya struktur-struktur sesar baru. Jumlah sesar bertambah dan sudut kemiringan sesar pun cenderung bertambah seiring dengan meningkatnya pemendekan. Semakin tebal lapisan pasir maka jumlah sesar yang terbentuk lebih sedikit sebaliknya semakin tipis lapisan maka jumlah sesar yang terbentuk lebih banyak. Perbedaan ukuran butir material akan menghasilkan pola struktur dan jumlah sesar yang berbeda pula.

Abstract

Korido is located in Supiori District , Papua , Indonesia . This area is in the north of the Central Range and included in the North Irian Basin which is the fore arc basin (Mc Adoo & J.C. Haebig, 1999). Own research area based on geology map created by Masria et al ( 1981) composed by Wainukendi Formation which is composed predominantly by carbonate sedimentary rocks .The purpose of this study is to determine the pattern of lithology and lithological boundaries were obtained from measured stratigraphy along the trajectory of research which is then integrated with the micro facies analysis and facies zone were obtained by petrographic analysis to determine the depositional environment and depositional processes that occur in Wainukendi Formation. More over, the relative age determination is also done based on the analysis of large benthic foraminifera so the deposition process can be integrated with relative age . The ultimate goal of this research is to integrate field data, micro facies analysis results and deposition process analysis results to create a model of sedimentation, determining stratigraphic marker, and the determines system tract that develops in Wainukendi Formation in the study area .The method used in this research is geological mapping focused on stratigraphy subjects in Korido area to get  lithostratigraphy sequence, platform type, sedimentation processes, and laboratory analysis include petrographic analysis to determine micro facies and facies zone and paleontological analysis to determine the relative age which then integrated to obtain stratigraphic marker and systems tract that develops in Wainukendi Formation. From the analysis of platform type showed the type of platform existing in this area is rimmed shelf type which is then used as a reference in micro facies analysis according to Wilson (1975) to obtain 4 facies zone that exist in this study area is reef platform margin , slope , toe of slope apron and deep shelf . Based on the analysis of the deposition process obtained 3 cycles of sedimentation that occurred from Wainukendi Formation . From the results of this analysis are used in determining the stratigraphic sequence to obtain stacking patterns that evolve based sequence boundary and its systems tract is composed of LST - TS - MFS - TST - HST so that obtain a full cycle changes in accommodation space and sediment supply where there is an increase in accommodation space which was offset by an increase in the supply of sediment in LST phase is characterized by progradation and agradation, an increase in the supply of sediment is lower than the increase in accomodation space in TST phase is characterized by retrogradation, and lastly, a decrease in accommodation space while sediment supply rate is still high in HST phase characterized by progradation.

Abstract

Kali Semarang is one of the watering pattern that was in Semarang, Central Java, which runs from Pandanaran heading north toward the Java Sea. At the time of Semarang and surrounding areas have a condition that there are no rocks exposed at the surface because it is an area of older alluvium and river stage consisting of loose material such as clay, so this area has soft soil conditions until very soft. Lowering occurs in the area of construction of the embankment caused by the soft soil in the area around the construction of the embankment. Judging from the condition of the soil is soft and very soft, so we must be careful in determining the appropriate and correct methods for prevention of ground movement. Based on the soil conditions in the area of Kali Semarang, a study was undertaken using data SPT (Standard Penetration Test) to see the condition of the soil strength, and then to increase the strength of the soil used a method which is the method of grouting.From the results of drilling conducted at the Gate House point E1 +10 m, known at depth 0-2 m of sand sized loose gravel gray. At a depth of 2-20 m in the form of clay sized soft to very soft with gray. From SPT test data at Gate House point E1 +10 m, obtained N - SPT values <2 (very soft) at a depth of 2.8 to 5.8 m and a depth of 10.4 to 11.7 m. 2-3 N - SPT values (soft) is at a depth of 7.8 to 8.8 m and a depth of 13.4 to 19.3 m. SPT N - values (very dust) contained in an area close to the surface that is at a depth of 1.4 m.Once implemented method of grouting on Retaining Wall section B point 13 +1 m, +2 m point C10, and C18 +2 m point, a change in the value of the SPT test that the higher the value of N-SPT 4 (very dust) its value changed to 10 -15 (rather dense). N-SPT value of 0-1 (very soft), and the N-SPT values 2-3 (soft) turned into a N-SPT values 3-4 (soft), the value of N-SPT 5-7 (firm,) and N-SPT values 8-13 (stiff). To pile foundation bearing capacity changes from 16.57 tons to 35,98 tons to 53,03 tons. From the results of this investigation obtained good results for the purpose of grouting method successfully to increase the carrying capacity of the soil at the study site.Judging from its success with the implementation of the construction of grouting method can be resumed because the carrying capacity of the land has allowed it to withstand the load of the building to be erected.
