Pengaruh Pemangkasan Batang dan Cabang Primer terhadap Laju Fotosintesis dan Produksi Jarak Pagar (Jatropha Curcas L.)

This research was aimed to study the effect of stem and primary branch prunning on photosynthetic rate and production of physic nut. The experiment was conducted in IPB experimental station in Cikabayan, Darmaga, Bogor, from February 2007 until May 2008. A randomized block design with one factor was used in the experiment. The treatments were combination between stem pruning with various height from the soil surface and pruning of primary branches with various number of branch remained. Stem pruning on 40 cm above the soil surface with no branch pruning resulted in the highest photosynthetic rate (8.10 µmol CO2 m-2 s-1), while stem pruning on 20 cm above the soil surface with 2 primary branches remained resulted in the lowest photosynthetic rate (4.71 µmol CO2 m-2 s-1). Stem pruning on 40 cm above the soil surface without branch pruning produced the highest yield components, i.e., capsul number (207.3 capsul plant-1), seed number (506 seeds plant-1) and seed dry weight (323.81 g plant-1)

The Influence of Difference Temperature Against the Rate of Embryonic Development and Larval Abnormality of Cantik Grouper (Epinephelus SP.)

Cantikgrouper is the hybridization results grouper or cross-breeding between Epinephelus fuscoguttatus as a female and Epinephelus microdon as a male. The main barriers faced in the development of this commodity is still low levels of spawning up to seeding grouper. Based on the background, this study aimed to investigate optimum temperature observations against the rate of embryonic development Epinephelus sp.larvae. This study used the results of artificial spawning eggs.The fertilized eggs were incubated on six pieces of the container temperature treatment;each treatment there was repeated three times.The incubation temperature was kept on (A) 21-22°C; (B) 23-24°C; (C) 25-26°C; (D) 27-28°C; (E) 29-30°C; (F) 31-32°C. Results showed that eggswere incubated at a temperature of 21-22 ℃ embryonic development to a halt in the blastula, and temperature 23-24°C stalled on phasemyomere embryos. The low-temperature incubation period lasts a long time. Temperature 25-26°C needed 18 hours 6 minutes by 8.33% abnormality rate. Temperature 27-28°C needed 16 hours to hatch witha degree of abnormality of 7.6%. Temperature 29-30°C needed 15 hours 1 minute for the hatch tothe degree of abnormality of 5.33%. The 31-32°C temperature needed 14 hours 6 minutes to hatch witha degree of abnormality of 17.3%. The limits of tolerance for the incubation of the eggs ofcantik grouper (Epinephelusspp.) were 26-32°C.The best temperature of each treatment were obtained at a temperature of 29-30°C. Based on our results, it concluded that the changing temperature affected how long eggs could hatch

Pemetaan Zona Rip Current Sebagai Upaya Peringatan Dini Untuk Bahaya Pantai (Lokasi Kajian : Pantai Kuta Bali)

Wisata pantai merupakan wisata favorit yang mengandung resiko tinggi. Bahaya pantai salah satunya adalah kecelakaan yang terjadi di wilayah pantai dan beberapa kasus kecelakaan yang terjadi di pantai biasanya akibat pengawasan yang lemah, kurangnya pemahaman wisatawan akan bahaya pantai, fasilitas pengawasan yang kurang memadai, atau wisatawan yang tidak dapat berenang kemudian terseret arus sampai ke tengah laut. Menurut Daryono (2010), arus yang membawa korban tersebut adalah Rip Current. Penelitian ini bertujuan untuk Tujuan penelitian ini adalah untuk mengetahui zona potensi rip current, Mengetahui persentase potensi terjadinya rip current di Pantai Kuta Bali. Metode penelitian yang digunakan adalah metode kuantitatif. Hasil penelitian menunjukkan bahwa Pantai Kuta Bali dibagi kedalam 2 (dua) zona, yaitu zona aman dan zona bahaya. Pada zona aman terdapat 2 (dua) pola rip current, karena gelombang yang datang tidak membentuk sudut yang tegak lurus terhadap garis pantai, sedangkan pada zona berbahaya terdapat 7 (tujuh) pola rip current. Persentase terjadinya rip current di sepanjang Pantai Kuta Bali adalah sebesar 83%, nilai ini berdasarkan kejadian gelombang pecah tipe plunging. Slope pantai akan mempengaruhi terjadinya rip current. Pada penelitian ini pantai landai memiliki potensi rip current paling besar yaitu sebesar 91.5% yang memiliki slope sebesar 7.5˚, berada pada koordinat 08˚43'23” LS dan 115˚10'9” BT. Sedangkan, pantai datar memiliki potensi rip current yang kecil yaitu sebesar 51.5% dan memiliki slope antara 0.5˚ sampai 1.8˚

Finding Islam in Cinema: Islamic Films and the Identity of Indonesian Muslim Youths

This paper discusses Islamic films in Indonesia that have been a phenomenon since a decade. It is reported that Islamic films have been consciously produced to propagate Islamic lessons to the Muslim youths. The paper challenges the notion that young adults are passive recipients as proposed by some popular culture theorists. They did not merely become object of ideologies injected by filmmakers, and their responses were not an unquestioning acceptance. The research found that some Muslim youths have been ambiguous toward the emergence of Islamic films. Watching movie for Indonesian youths is an important way to construct identity, and they feel that there is a sense of religious ritual involved in film viewing, especially with Islamic messages. I argue that Islamic films help Indonesian young people to develop their own distinctive identity, being new sources of authority apart from parents, formal education, and friends.[Tulisan ini membahas film islami di Indonesia yang menjadi fenomena sejak satu dekade terakhir. Film-film islami sengaja dibuat untuk menyebarkan ajaran Islam dengan sasaran kalangan muda. Makalah ini menolak gagasan bahwa remaja adalah penerima pasif seperti yang diajukan oleh teori budaya popular. Mereka tidak hanya menjadi objek desakan ideologi pembuat film dan mereka juga tidak bisa menerimanya secara bulat. Sebagian pemuda muslim merasa ambigu menghadapi munculnya film-film Islam. Di sisi lain, menonton film menjadi media untuk membangun identitas diri dan dapat dirasakan sebagai bagian dari ritual agama, khususnya ketika menonton film yang mengandung pesan-pesan Islam. Dengan demikian, film Islam membantu pemuda Indonesia untuk mengembangkan identitas mereka sendiri dan menjadi sumber otoritas baru di luar orang tua, pendidikan formal, dan lingkungan pergaulan.
