Research ArticleOpen accessUtilization of Holt's Forecasting Model for Zakat Collection in IndonesiaAkbarizan, Muhammad Marizal, M. Soleh et al.The practice of zakat is gaining popularity in Indonesia. This development is attributed to the strong role of the government in consistently developing zakat infrastructure and the increased awareness of people to practice zakat. Despite this success, a mechanism for predicting future zakat collection has not yet been developed. This study applies Holt's exponential smoothing and Auto-Regressive Integrated Moving Average … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 22 Dec 2016 · 7,499 accessesView PDF Cite

Research ArticleOpen accessContinuity Function on Partial Metric SpaceFitri Aryani, Hafiz Mahmud, Corry Corazon Marzuki et al.Ordered pairs form of a metric space (S,d), where d is the metric on a nonempty set S. Concept of partial metric space is a minimal generalization of a metric space where each x∈S,d(x,x) does not need to be zero, in other terms is known as non-self-distance. Axiom obtained from the generalization is following properties p(x,x)â‰¤p(x,y) for every x,y∈S. The … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 13 Nov 2016 · 7,205 accessesView PDF Cite

Research ArticleOpen accessDesign Maximum Power Point Tracking (MPPT) on Photovoltaic Panels using Fuzzy Logic MethodAhmad Faizal, Sutoyo, Mulyono et al.Solar energy is a clean energy, renewable, and available for the long term. The tool used to convert the energy generated from the intensity of sunlight into electricity is photovoltaic panels. However, due to the high cost and low efficiency, the use of the energy is still kind small compared to other types of energy sources. Thus, the need for … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 10 Aug 2016 · 8,498 accessesView PDF Cite

Research ArticleOpen accessDrying Characteristics of the Borneo Canarium odontophyllum (Dabai) FruitDayang Fredalina Basri, Ahmad Fudholi, Mohd Hafidz RuslanThe quality and shelf-life of an underutilized fruits are compromised by the conventional method of drying. We therefore proposed using hot-air chamber to develop the drying curves of Canarium odontophyllum (dabai) fruit. Present study provides evidence of the best mathematical model to demonstrate the drying characteristics of this indigenous fruit and thus, may generate or add to the existing database. … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 5 Sep 2012 · 8,946 accessesView PDF Cite

Research ArticleOpen accessAnalytical and Experimental Studies on the Thermal Efficiency of the Double-Pass Solar Air Collector with Finned AbsorberAhmad Fudholi, Kamaruzzaman Sopian, Mohd Hafidz Ruslan et al.Problem statement: The design of suitable air collectors is one of the most important factors controlling the economics of the solar drying. Air type collectors have two inherent disadvantages: Low thermal capacity of air and low absorber to air heat transfer coefficient. Different modifications are suggested and applied to improve the heat transfer coefficient between the absorber plate and air. … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,415 accessesView PDF Cite

Research ArticleOpen accessThermal Efficiency of Double Pass Solar Collector with Longitudinal Fins AbsorbersAhmad Fudholi, Kamaruzzaman Sopian, Mohd Hafidz Ruslan et al.Problem statement: One of the most important components of a solar energy system is the solar collector. The performances of double-pass solar collector with longitudinal fins absorbers are analyzed. Approach: The study involves a theoretical study to investigate the effect of mass flow rate, number and height of fins on efficiency, which involves steady-state energy balance equations on the longitudinal … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 8,066 accessesView PDF Cite
