Abstract

Snakehead is a kind of fresh water fish that still taken from the nature, which is the yieldof it fishing are unreliable. Therefore, the aquaculture technique is needed. Criticalphase of snakehead aquaculture is choosing suitable feed for larvae. Based on this problem, information about first feed suitable for larvae is very important.The aim of the research is to know about growth and survival rate of snakehead larvae with differentfeed. The research was done in 21 days at the Center for Research and Development ofFreshwater Aquaculture Bogor. Larvae with first weight 0.4±0.07 mg and length 4.56±0.53 mm were used. Fish were feed three times daily in ad satiation. Experimentaldesign used was completely randomized design four treatment with three replications,namely A (egg yolk chicken), B (Moina sp,), C (Artemia sp.) and D (silk worm).Parameters measured were the absolute length growth, the growth of absolute weight,specific growth rate, survival rate and feed efficiency. Water quality parameters weretemperature, pH, DO and conductivity. The result showed that the used of silk worm asfirst feed for larvae indicated the best performences. The growth of the absolute length of13.34±1.30 mm, absolute weight of 54.52±2.93mg, specific growth rate 23.85±0.21%,survival rate 97.67±2.36% and feed efficiency 82.69±7.79%.  Keywords : feed, growth, larvae, silk worm, snakehead, survival rate.

Abstract

This article tries to describe the thought of Muhammad Abdullah Darraz about the i’jaz of the Qur'an in his work an-Naba' al-’Azim: Nazarat Jadidah fi al-Qur'an. Thorough this work, Darraz emphasizes the things that become the domain of the i’jaz al-Qur'an plus debates the people who doubted it. Uniquely the study on the i’jaz of the Qur'an in this book is not only discussing theological doctrines but also excellence and incomparability (al-mu’aradah), challenges (at-tahaddi), inability to respond the challenge (ar kal-mu’aradah) and weaknesses (al-’ajz) which lead to the superiority of the Qur’an. Moreover, Darraz could take the study of i’jaz (miracles) to the area of the principle of interpretation whose study is not only theoretical but also conceptual and even applicative one. In general, the Darraz ideas of i’jaz (miracle) of the Qur'an are four important points: the first is about character of the structure of the Qur’an which is marvelous. The structure covers the beauty of the sound of the series of letters and the letter marking, short but full of meaning which satisfies the reason and soul, uses the pronunciation with the precise meaning and uses the various structure of sentences; the second is that the character of the discourse is suprarational; the structure of the meaning is intertwined; and the fourth is that Darraz can present various meaning of the words in the Qur’an.

Abstract

Groundwater is the water contained in bedrock or regolith, it can also be said to flow naturally to the surface of the soil through jets or seepage. Groundwater has an important role especially for human needs. The research area is administratively located in Cipatat District, West Bandung Regency. Geographically it is located at 6°46'4.84" LS – 6°53'54.30" LS and 107°18'7.44' E – 107°28'53.23" E. The development of the Cipatat area in industrial, service, trade and residential activities can affect the use of groundwater and will continue to increase. The purpose of this study was to identify the potential of water resources using remote sensing methods supported by Geographic Information Systems (GIS), data processing using secondary data and conducting field checks. Satellite image processing classifies Cipatat land class images divided into 4 types of land, from low to high pixel values, namely water body distribution land, ground cover vegetation, plantation vegetation and grasses, as well as forest vegetation, dry fields, and rocky soils. The results of data processing showed that the water critical areas in the study area had a percentage of 3-10% in Bojongheulang, Cipageran, Cirawemekar Mandala sari dan Rajamandala and safe areas with a percentage of 11-51% in Campaka Mekar, Ciburuy, Cihea, Cipatat, Gunung Masigit dan Padalarang. Based on the correlation test of the distribution area of ​​Cipatat and its surrounding vegetation with the distribution area of ​​groundwater, it shows a strong relationship and influences each other. Field checks were carried out in the North and South Cibatat areas.
