Abstract

Researchers have widely applied heat shock on zygote stadia of domesticated aquatic animals especially for the purpose of ploidy manipulation in fish to accelerate growth, intermediate products for the production of infertile seeds, providing prospective brood stock as well as the monosex population.  This is certainly an interesting study to see how far the impact of heat shock on the early development stages. This experiment used a 42 0C heat shock for 2.5 minutes on the zygote at different initial time i.e. 28.5; 29; 29.5; 30 and 30.5 minutes after fertilization. All treated larvae and control were reared in a 25 liters plastic container at density of 5 larvae per liter. The results showed that high percentage of fertilization rate were 92.61 % to 96.32 % and hatching rate was 85.33 % without any abnormalities were achieved in the control. While in all treatments had a very low hatching rate of 4.12 % to 8.93 % with relatively high abnormalities of 12.36 % to 27.60 % and a significant differences (P<0.05) compared to controls, but survival rate, specific growth rate and feed conversion ratio after 30 days rearing period showed no significant difference (P>0,05). In terms of seed production, the heat shock treatment will limit 78 % to 82 % of larvae production.

Abstract

Striped catfish tetraploid induction through heat shock that carried out in this study is not intended to produce on growth fries.But to form a broodstock to produce triploid on growth fries through cross breeding without any physical shock induction process.The fries from the heat shock induction in the previous study were screened or selected by observing the maximum number of nucleoli in fin cells.The number of tetraploid individuals used in the performance test was 105 which were placed in three different concrete tanks.The results showed that the growth of tetraploid striped catfish was more significant than diploid with a difference in the daily weight percentage about 0.497% and 0.158% for length but insignificant differences in FCR and SR.In gonadal development based on histological observations, it was shown that each tetraploid and diploid both male and female striped catfish were at the same level of gonadal maturity.Female gonads were at the previtellogenic oocytes and vitellogenic oocytes, but males are dominated at the stage of spermatocytes and spermatozoa.This histology also shows us that the female gonad was still at the development stage, while the male had entered the mature stage and ready to be spawned.

Abstract

The researcher has succeeded in synthesizing the Ferri Salen-Taenolite complex as a clay based catalyst and applying it to the reaction of glycerol carbonate formation. Lewis acidity of the catalyst complex can increase through the immobilization process in addition, the activity and selectivity of the catalyst also increase. The formation of salene ligands is shown by the appearance of the peak C=N at the wave number around 1640 cm-1 and the O-H peak around 3400 cm-1. The formation of the Fe(salen)NO3 complex is indicated by the reduction of the vibration intensity O-H at the wave number of about 3400 cm-1 and the shift of the peak C=N in the area around 1640 cm-1 to 1690 cm-1. The complex [Fe(salen)]NO3 has been synthesized with physical properties in the form of brown powder and effective magnetic moment by 2,197 BM. The complex [Fe(salen)] + was successfully immobilized into the LiTN as much as 9.12 mmol/g LiTN. Based on the catalytic activity test, the catalyst was active in the reaction of polycarbonate monomer formation which is indicated by a change in vibration of the urea carbonyl (CO amine) group at wave number 4242 cm-1 to vibrate the carbonyl group (CO ester) at wave number 1786 cm-1 which indicates that glycerol carbonate has been formed.

Abstract

Awal mulanya, peradaban India, Persia dan Yunani adalah peradaban yang punya kedudukan istimewa. Dari tiga peradaban inilah secara khusus muncul dan lahirnya per- adaban falak Arab (Islam), di samping peradaban lainnya. Peradaban India adalah yang terkuat dalam pengaruhnya terhadap Islam (Arab). Dalam melihat perkembangan ilmu  Falak secara historis, dapat diperiodesasikan menjadi Ilmu  Falak sebelum Islam, ilmu Falak dalam peradaban Islam, ilmu Falak dalam peradaban Eropa dan ilmu Falak di Indonesia

Abstract

Hukum Islam sebagai ketentuan yang mengatur nilai-nilai hukum perbuatan ummat manusia terutama para mukallaf yang sumber utamanya Al-Qur’an dan Hadis, telah mengatur hubungan manusia dengan Allah dan hubungan manusia dengan sesama manusia dan alam sekitarnya.   Hukum Islam dalam menata kedua hubungan dimaksud, terdapat aturan atau ketentuan yang bersifat jelas dan terperinci yang mengandung tuntutan mengamalkan dengan penuh ketaatan, keikhlasan dengan mengharap ridha Allah Swt. Hal ini biasa disebut  “ibadah mahdah”. Di sisi lain, terdapat ruang yang bersifat pleksible memberikan kewenangan pada akal pikiran berijtihad untuk menemukan kejelasan hukum suatu persoalan yakni bidang muamalah.Istilah hisab dan rukyat, pada dasarnya adalah manhaj (metode) dan bukan syariah. Sebagai suatu metode, tentu dapat menjadi pilihan dalam penerapannya di mana suatu umat berada dengan kondisi masanya. Dalam sejarah perjalanan umat Islam khususnya di Indonesia, terdapat perbedaan pilihan penerapan metode ini. Ada yang menerapkan hisab secara murni (hisab hakiki ) seperti Persyarikatan Muhammadiyah pada semua bulan kamariyah, waktu shalat, arah kiblat hingga perhitungan gerhana dan ada yang memilih hisab dibuktikan dengan rukyat yakni Nahdatul Ulama dan  kementerian Agama Republik Indonesia atau imkanun rukyat, khususnya pada tiga bulan kamariyah yaitu . awal bulan Ramadhan, awal bulan Syawal dan awal bulan Zulhijjah. Selain ketiga bulan tersebut, Nu dan Kemenag juga menggunakan hisab secara murni

Abstract

A research about the utilization of red dragon fruit extract (Hylocereus polyhizus) as reducer of Fe (III) metal ions has been done. This research aims to determine the optimum condition of reducer solution of dragon fruit extract to reduce Fe (III) metal ions based on variation of Fe solution concentration and also ph variation with Na2S2O3 reductant as comparison. The results showed that the optimum concentration of the dragon fruit extract reducer agent could reduce Fe (III) metal ion to Fe (II) at a concentration of 10 mg / L, Fe reduced as much as 1.187 mg / L, while the optimum pH is at pH 5 when Fe reduced of 1.436 mg / L. The concentration of Na2S2O3 reducant was at concentrations of Fe 10 mg / L with reduced Fe of 0.538 mg / L while the optimum pH was at pH 5 with a reduced Fe of 0.511 mg / L. From the results of this research with both reducers it can be seen that the dragon fruit extract reduces Fe metal ion better than the reduction of Na2S2O3. Keywords: Fe metal ion, reductant, dragon fruit extract (Hylocereus polyhizus), Na2S2O3, determination of % Fe is reduced, optimum pH.
