    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

    Get PDF
    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

    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

    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

    Get PDF
    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

    Implementation of the Simple Multi Attribute Rating Technique Method (SMART) in Determining Toddler Growth

    Toddler nutritional status is an important factor in efforts to reduce child mortality. The development of community nutrition can be monitored through the results of recording and reporting of community nutrition improvement programs reflected in the results of weighing infants and toddlers every month at the Pos Pelayanan Terpadu (Posyandu/ Integrated Service Post) , where these efforts aim to maintain and improve health and prevent and cope with the emergence of public health problems, especially aimed at toddlers. However, in carrying out the health service activities of Medical Officers, faced with an important problem that is still difficult in providing information related to the results of monitoring the growth and development of infants, because information on growth and development of infants owned is obtained from the data collection done manually such as; make records and calculations to find out the condition of a toddler declared good, less, or bad. Implementation of the SMART method in Toddler's growth and development, this method can be used based on the weights and criteria that have been determined. The criteria used are based on the Anthropometric index assessment criteria. The results of the analysis are the results of ranking the greatest value to be used as the material in the decision-making process
