    Communication in Physical Sciences 2020, 5(1): 34-41 Authors: F. G. Okibe, G.A. Shallangwa, I. Usman Received 10 March 2020/Accepted 01 April 2020 The White method for determination of 5hydroxymethylfurfural (5-HMF) content in honey was successfully modified using Perchloric acid (HClO4) as replacement for zinc acetate (Zn (CH3CO2)2·2H2O) and potassium ferrocyanide (K4Fe (CN) 6·3H2O) to serve as Deproteinizing agent, and Sodium bisulphite (NaHSO3) was replaced with sodium pyrosulphite (Na2S2O5) for the chromophore removal of 5-HMF at 284 nm. The proposed method was validated by evaluation of parameters such as linearity, precisions (reproducibility and intermediate), accuracy, and limit of detection (LOD), limit of quantification (LOQ), ruggedness and robustness. The correlation coefficients for the calibration curves were 0.9994 and 0.9923. The method is in agreement with Beers- Lamberts law at the concentration range of 5, 10, 15, 20 and 25 mg/kg. The values of reproducibility and intermediate precision in honey samples were 2.65, 2.67, 3.03, 4.73, and 1.90 % respectively. The recoveries for the analyses were between 81.4 % and 104.6 %, LOD and LOQ were 0.12 and 0.36 mg/kg at 284 nm and 0.06 and 0.17 mg/kg at 336 nm respectively. The ruggedness of the method was 1.23 and 1.00 %, and the robustness were 0.64 and 0.42 %. The results obtained suggest that Perchloric acid and sodium pyrosulphite can successfully replace zinc acetate, potassium ferrocyanide and Sodium bisulphite which are scarce and expensive reagents. The Modified method is suitable for routine determination of 5-HMF in honey samples References Abraham, K, Gürtler, R, Berg, K, Heinemeyer, G, Lampen, A. & Appel, K. E. (2011).

    This study was conducted in the Bali strait held from 2 to 16 April 2014 aimed to study the effect of environmental parameters on purse seine catches in the Bali strait such as temperature, salinity, current speed, depth, and pH , and the type of fish caught in the waters of the Bali strait. The method used in this research is the method of experimental fishing that by measuring and observing directly the environmental parameters in which it operates Purse Seine. The data collected in this study were: temperature, salinity, current speed, depth, and pH, and the type of fish caught. The catch and the measurement of these parameters are collected and then tabulated into a table and analyzed.The observation of environmental parameters during the study is the temperature range between 26-280 C, salinity ranges between 30-33 0/00, currents ranging from 0.3 to 0.5 m/s, water depths ranging from 64-78 m , and the pH of the water ranges from 7 - 8. The type of fish that were caught at Bali Strait is Sarden (Sardinella lemuru), mackerel scad (Decapterus mackarellus), and swordfish (Euthynnuss affinis)

    Perintisan Ushul Fiqh dan Kategorisasinya

    Kebolehan berijtihad yang dilakukan para sahabat atas petunjuk Rasulullah melalui beberapa riwayat, menunjukkan bahwa metodologi penetapan hukum Islam tersebut telah tumbuh sejak masa Rasulullah, dan hal ini dilakukan juga oleh para sahabat yang sangat memahami benar bagaimana Rasulullah menetapkan suatu keputusan hukum yang diajukan pada beliau. Akan tetapi metodologi ini tidak tersusun selayaknya susunan suatu ilmu. Kedekatan para sahabat dengan Rasulullah sangat memungkinkan mudahnya para sahabat dalam berijtihad, sehingga metodologi bukanlah suatu keharusan pada masa tersebut. Walaupun sebenarnya dalam tataran praktisnya metodologi ini telah dipraktekkan pada masa sahabat.Dengan meluasnya wilayah kekuasaan Islam ke belahan dunia Barat dan Timur, dari daratan Spanyol sampai perbatasan Cina, dan berkembangnya berbagai bidang ilmu pada masa Tabi\u27in, tidak hanya berdampak pada beragamnya persoalan hukum yang terjadi di masing-masing wilayah tersebut, tapi juga sering terjadi perbedaan antara ulama disetiap wilayah dalam memutuskan persoalan hukum yang dihadapinya, walaupun persoalan hukum yang dihadapi ulama saat itu memiliki kesamaan kasus. Atas dasar ini lahirlah beberapa aliran dalam menetapkan metodologi hukum Islam, yang dijadikan acuan masing-masing kelompoknya. Terdapat aliran Jumhur ulama ushul fiqh yang membangun metodenya secara teoritis, tanpa terpengaruh pada masalah furu\u27. Aliran Fuqaha yang justru banyak dipengaruhi oleh masalah furu\u27 dalam mazhab mereka, dan terdapat pula aliran yang mengkompromikan keduanya
