Training students to develop creative and innovative talents

Creativity is the ability of a person that enables him/her to think of, dream up or visualize unusual solution to a problem. It plays an important part in the development of a nation. Generally, a creative process involves five significant steps: first insight, preparation, incubation, illumination and verification. Innovation, on the other hand, is the process of reducing creative ideas to practice, making some systems, components or equipment. The success of a creative process depends to a great extent on the individual, and the environment that exists around him / her. The generation of ideas is considered one of the most important elements, where brain-storming plays an important role, which is subjected to stringent evaluation process before being implemented. An encouragement and support from educators towards creative signs of students would help in the development of creativity. An awareness of creative and innovative process and an involvement in the solution of a creative problem may help students to develop creative and innovative talents. To promote creativity and innovation, areas e.g. projects, laboratory experiments, design of systems and components, where opportunities exist for the development of creativity, should be identified to play an active role in it

The Effect of Filler Content on Mechanical Properties of Polypropylene/Clay Nanocomposites

This study investigated the effect of filler content on mechanical properties of polypropylene. There are synthesis clay and un-synthesis clay used as filler content. Different ratio of clay in polypropylene to study which ratio has a better mechanical property. The tensile test was carried out using INSTRON5565 and the maximum stress, strain, and modulus of elasticity observed. The experimental results showed that polypropylene/clay nanocomposite has a higher maximum stress compare to pure polypropylene and un-synthesis clay. Besides that modulus of elasticity of specimen calculated and finds that it increased with increment filler content and strain did not affect by filler. The synthesis clay filled into polypropylene will have a better mechanical property.  Keywords: nanocomposite, polypropylene, synthesis cla

Desalination: conversion of seawater to freshwater

Desalination methods are used to convert saline/brackish water to drinkable freshwater. Major processes use either thermal energy (conventional distillation) or pressure energy (Reverse osmosis). Different methods of desalination are discussed and their influence on overall water production has been highlighted. With the increase in appreciation for a green technology, desalination methods using renewable/waste energy are drawing significant attention in recent years. Applying different methods of desalination for coastal areas in Peninsular Malaysia can be very promising in terms of overall public health and economy

Fatty acid profile of various fresh water and marine fishes at different geographical locations. / Tengku Nurul Diyana Tg Zainal Alam Shah

The comparison on the fatty acid compositions of one marine fishes Rastrelliger kanagurta and one freshwater fish Monopterus albus in two different locations which is Kelantan and Pahang with different environmental factor were studied. Result showed that the lipid content of Monopterus albus is 8.36% in Kelantan and 0.84% in Pahang. Whereas, lipid content of Rastrelliger kanagurta is 9.69%in Kelantan 1.60% in Pahang. In the fatty acid analysis, it was discovered that the major fatty acid in the oil from the Rastrelliger kanagurta, between Kelantan and Pahang recorded the highest PUFA specifically DHA and EPA regarding to nutritional aspect with 48.51% and 48.33% followed by freshwater species, Monopterus albus (eel) members between Kelantan and Pahang with 13.32% and 6.32% respectivel

Histopathological study of nasal masses, a one year retrospective study in a tertiary care centre of Assam

Background: Prolapsed lining of the nasal sinuses are defined as nasal polyp. Diseases of the nasal cavity include viral, bacterial and fungal infections, nasal cavity tumors (benign and malignant) as well as inflammations of the nasal mucosa. This study was undertaken to note the various histopathological patterns of nasal masses, their classification and relative distribution of various lesions with regard to age and sex in our setting.Methods: The study is done for a period of 1 year (July 2018 to June 2019). In this study, 30 patients are selected who presented in our hospital with nasal masses and having multiple types of clinical presentations.Results: Total 30 cases presented as nasal mass. Overall male to female ratio was 2.3:1. Nonneoplastic nasal masses formed the largest group of lesions; 24 cases (80%), followed by 6 cases (20%) of neoplastic nasal masses. Inflammatory polyp was the commonest non neoplastic lesion constituting 22 cases followed by rhinosporidiosis with 2 cases. Out of the 6 neoplastic nasal masses, 5 were benign and 1 was malignant. Out of the benign neoplastic masses, inverted papilloma constituted 3 cases and nasopharyngeal angiofibroma constituted 2 cases. Malignant neoplastic mass was embryonal rhabdomyosarcoma.Conclusions: Nasal obstruction and rhinorrhea are the most common symptoms of presentation. Simple inflammatory nasal polyps are the most common histological pattern seen in our environment, and surgery is the best modality of treatment

Sosialisasi Pentingnya Koperasi di Sekolah

Sekolah dasar Islam Terpadu (SDIT) dan MDTA serta pondok tahfizh. Yang mana dalam pengelolaan yayasan tersebut sangat minim sekali pengetahuan dari pemilik serta kepala sekolah dan guru guru untuk mendirikan koperasi bagi siswanya. Dan saat ini hanya memilki sebuah Kantin yang mana Kantin tersebut dijadikan sebagai tempat menjual peralatan yang dibutuhkan oleh siswa, seperti halnya: Buku tulis, Pulpen, Pensil, Penggaris serta snack atau makanan ringgan bagi siswa sekolah tersebut. Kegiatan pengabdian ini dilakukan dengan metode percobaan langsung di lapangan. Kegiatan diawali dengan penyampaian materi yang berhubungan dengan tema yang sedang dilaksanakan Berikut ini adalah tahapan pelatihan yang dilakukan: (1) Tahap Persiapan, (2) Tahap Pelaksanaan Pelatihan, (3) Metode Sosialisasi, (4) Metode Simulasi. (Suparmi, Suwena, and Meitriana 2020). Berikut hasil yang ditemukan dilapangan bahwasannya belum maksimal terlaksananya koperasi di SDIT Ar-Ridha Desa Pantai Cermin Kec. Tanjung Pura. Hal ini dikarenakan para guru, pimpinan sekolah dan orang tua tidak memahami arti pentingnya koperasi di sekolah. Oleh sebab itu, tim PkM mempunyai inisiatif untuk memberikan pelatihan atau sosialisasi tentang Pentingnya Koperasi di Sekolah. Pemberian Sosialisasi ini tidak hanya berguna bagi pemilki sekolah dan guru, tetapi juga penting bagi peserta didik maupun orang tua/wali siswa

Adsorption of Pb (II) Heavy Metals from Wastewater Using Modified Rice Husk as Adsorbent

Pb (II) heavy metal from wastewater as by-product of industrial activity often causes problem to environment. In order to minimize the amount of Pb (II), wastewater was treated in various ways, including adsorption process using adsorbent. Rice husks that containing lignin, cellulose, and hemicellulose are one of potential candidates to be utilized as adsorbent. The purpose of this research is to modify rice husk by using sodium hydroxide and citric acid and to know adsorption capacity and adsorption efficiency of modified rice husk adsorbent on Pb (II) metal uptake from wastewater. To identify substituted groups, analysis samples by using Fourier Transform Infrared was performed and to determine adsorbed amount of Pb (II) into adsorbent an Atomic Adsorption Spectroscopy Method was conducted. The result showed that optimum adsorption capacity and adsorption efficiency was 5.08 mg/g and 84.52%, respectively. These results were obtained on 60 ppm of Pb (II) adsorbate concentration and 0.8 M citric acid concentration for 150 minutes of contact tim
