Overview of Indonesian Islamic Education: A Social, Historical and Political Perspective
The aim of this study is to examine how the historical genealogy of Islamic educational tradition, particularly the tradition of teaching and learning, has contributed to the development of Islamic education in Indonesia. By drawing together in an analytic way a historically based description of the social and political circumstances surrounding Indonesian Islamic education, the study discusses some significant issues concerning the religious base, knowledge base, structural form, and the pedagogical approach of Indonesian Islamic education, all of which are important to the development of a modern form of Islamic education.
The argument of the thesis is that the existing values of the Islamic tradition in education, particularly evident in Madrasah schools, provide a valuable basis for further developing and reconstructing an effective Islamic education system in Indonesia. However, there is also a strong need to construct an Islamic education curriculum in Indonesia that can meet the challenge posed by the circumstances generally understood as 'modernity'. The quality of teaching and learning in the Madrasah are very much influenced by the quality of the wider Islamic education programme. Any change in the curriculum of Islamic education will thus have significant effects on the quality of the Madrasah schools in Indonesia. This thesis will thus conclude by suggesting some implications for further development of Islamic education that arise from the study.
This is a qualitative study using an historical genealogical approach to discover, understand and analyze the challenges currently facing Islamic education In Indonesia. The techniques for collecting data involved, primarily, a critical reading of historical and contemporary policy documents. Primary and secondary sources were also collected, studied and subjected to a critical reading in the production of this account of Indonesian Islamic education
Lymphangioma in nasal tip and vestibulum: Case report
A ‘Pinocchio’ or ‘Cyrano’ nose is a condition with a deformity at the tip of the nose caused by an underlying soft tissue tumor. The deformity of the nose with secondary involvement in the form of lymphangioma is a sporadic case, and few studies have reported it. Lymphangioma itself is a benign tumor that originates from the lymph vessels. The diagnosis of lymphangiomas can be made based on the clinical picture and computed tomography (CT) or magnetic resonance imaging (MRI) scans. Treatment options for nasal tip lymphangioma and nasal vestibule are radiotherapy, cryotherapy, and sclerosant injection
Reproductive Characteristics of Female Egg-carrying Buntingi, Xenopoecilus oophorus, an Endemic Fish to Lake Poso in Central Sulawesi
Reproduction characteristic of female egg-carrying buntingi, Xenopoecilus oophorus had been studied. This research was conducted at Lake Poso, Central Sulawesi, Indonesia. Specimens were collected monthly from August 2012 to July 2013 at four sampling stations around the lake. Macroscopic observations of ovarian maturity level and gonadosomatic index revealed a long reproductive period during the rainy season, with four spawning peaks in November, January, February and April. The highest total fecundity was 135 oocytes, and the highest batch fecundity was 36 oocytes. Analysis of the oocyte diameter frequency distribution showed X. oophorus is a multiple spawner. Batch fecundity was correlated (r = 0.78) with body weight
Komposisi Makanan dan Strategi Makan Ikan Famili Gobiidae di Teluk Pabean, Indramayu
The objectives of this study were to identify and evaluate diet composition and feeding strategy of Gobiid fishes in Pabean Bay, Indramayu. Fishes were collected monthly using gill nets, shrimp nets and fixed trap nets from April 2016-March 2017. Diet composition and feeding strategy were analyzed by IRI (Index of Relative Importance) and modification of the graphical Costello method, respectively. Nine species of Gobiidae were captured during the study period, namely Acentrogobius caninus (with total body length range 46-115 mm), Acentrogobius cyanomos (49-108 mm), Boleophthalmus boddarti (95-189 mm), Glossogobius aureus (70-210 mm), Oxyurichthys tentacularis (88-130 mm), Parapocryptes serperaster (112-198 mm), Paratrypauchen microcephalus (100-150 mm), Pseudapocryptes elongatus (88-190 mm), and Taenioides cirratus (160 mm). According to the diet analysis, A. caninus, A. cyanomos, and G. aureus were grouped into crustacivore, while the B. boddarti, P. serperaster, P. microcephalus, and P. elongatus were categorized as phytobenthic feeder. A. caninus, G. aureus, and A. cyanomos exhibited a specialist feeding strategy with the main food was Metapenaeus sp., Metapenaeus sp. and Acetes sp., respectively. B. boddarti, P. serperaster, P. microcephalus, P. elongates displayed a generalized feeding strategy. This research showed that Gobiid fishes occupy different trophic levels and play an important ecological role in Pabean Bay
