منشی اقبال احمد

منشی اقبال احمد
افسوس ہے کہ ۶؍ دسمبر کو منشی اقبال احمد صاحب بھی حرکت قلب بند ہوجانے سے انتقال کرگئے، وہ ماہر کاتب تھے، اپنی پوری زندگی دارالمصنفین کی خدمت میں گزاری، اس کی اکثر کتابیں ان ہی کے خط سے نکلی ہیں، اپنی خوشنویسی کی وجہ سے اترپردیش اردو اکاڈمی سے انعام بھی حاصل کیا، اب بصارت کی کمزوری کی بناء پر کتابت ترک کردی تھی، ان میں غرور و گھمنڈ نہ تھا، اپنی نرم اور شیریں گفتگو سے لوگوں کا دل موہ لیتے، اﷲ تعالیٰ ان کی بشری لغزشوں سے درگزر کرے اور انھیں اپنے سایہ رحمت میں جگہ دے۔
(ضیاء الدین اصلاحی، دسمبر ۱۹۸۸ء)

 

KETERAMPILAN PROSES SAINS PADA PRAKTIKUM IPA MATERI ASAM BASA PADA MAHASISWA PGMI IAIN PALU

The purpose of this study was to describe the science process skills of  students of  PGMI FTIK IAIN Palu on the science  laboratory of Asam Basa. This research is a descriptive study conducted at the PGMI Study Program in September to October 2019. The research subjects were students of semester 3 of PGMI in the academic year 2019/2020 who took 28 natural science courses. Data in the form of students' Science Process Skills were obtained from the student performance appraisal in the science practicum on acid-base material. The results showed that students' science process skills varied in each category. For the category of skills using tools and materials, the average percentage for the 2 indicators is 83.05% or very high. For the category of observation skills, the average percentage for the two indicators is 83% or very high. For the grouping / classification skills category, the average percentage for the 2 indicators is 79% or in the high category. Whereas for communication skills where in this category there are 3 indicators with an average indicator of 82.5 or very high. Overall by averaging the percentage of all indicators obtained the percentage for science process skills in science lab, wet acid material is 82%. This shows that the science process skills of PGMI students are very high.

Downstream Approaches for Pure Biofine Chemicals and Aroma Substances from Cannabis Sativa Essential Oil

Essential oils are complex mixtures of biologically active substances used since along time as flavoring agents and constituents of number of commercial products. Currently, their importance is more highlighted due to their increasing demand for food,cosmetics and pharmaceutical industries. Recent scientific literature revealed theantimicrobial, antifungal, antioxidant and pharmacological potential of essential oils. In view of themultiple applications of essential oils, their characterization based on their chemicalprofiles, is of great importance.In the present study, indigenous specie of Cannabaceae family “Cannabis sativa” was screenedfor the isolation of essential oils. Essential oil components were fractioned, separated and isolated. The variations in the yield, chemical composition and biological activities of theessential oils and fractions were investigated in the present study with respect to temperature and technique of extraction.The hydro-distilled, steam distilled and supercritical fluid extracted essential oils were characterized fortheir physico-chemical and biological activities. It was tried to purify and separate the major constituents of Cannabis sativa essential oil by vacuum fractionation. GC-MS analysis of thechemical constituents of the isolated oils and fractions mainly revealed the presence of monoterpene hydrocarbons, sesquiterpene hydrocarbons, oxygenated monoterpenes, and oxygenated sesquiterpenes. The investigated essential oils and fractions exhibited good antioxidant, antimicrobial, cytotoxic, insecticidal, anti-inflammatory, antitumor, gastroprotective, nephroprotective, hepatoprotective activities as measured by different in- vivo and in-vitro assays and experimental models.
