Jumlah civitas akademik Universitas Ma Chung yang semakin meningkat setiap tahunnya, membuat jumlah kendaraan bermotor milik pribadi baik roda dua maupun roda empat meningkat pula. Peningkatan jumlah kendaraan tersebut akan menyebabkan jejak karbon. Langkah Universitas Ma Chung untuk melakukan penyegahan jejak karbon yang terus menerus meningkat tersebut adalah mengadakan program kampus berwawan lingkungan (Eco Campus). Dalam mencapai hal tersebut dilakukan rancangan causal loop diagram, simulasi pemodelan sistem dinamis (stock and flow diagram) dengan software Stella untuk mendapatkan skenario usulan terbaik. Berdasarkan hasil penelitian didapatkan skenario usulan terbaik berupa pelaksanaan hari bebas kendaraan (car free day) dua kali dalam sebulan. Melalui skenario usulan tersebut didapatkan hasil perhitungan stock and flow diagram total nilai tapak karbon kendaraan bermotor di Universitas Ma Chung berkurang sebesar 517,2 ton of kg CO2untuk satu tahun kedepan dari kondisi awal.

During the Covid-19 pandemic, the government issued a policy through Large-Scale Social Restrictions and the impact was felt on the unsustainable availability of various food commodities, one of which was broiler chicken meat. Broiler chicken is one of the animal protein food products that is favored by people from various circles because it has a relatively cheaper price compared to other meat commodities that provide animal protein, is easy to obtain, and has good organoleptic quality. The purchasing power of the people of the Special Region of Yogyakarta (DIY) is also increasing due to increased nutritional awareness related to the fulfillment of animal protein. The broiler production process contains uncertainty because it is seasonal. This causes a fluctuating price change. Fluctuations in broiler prices are not a new phenomenon in the DIY. Price fluctuations usually occur at certain times such as during religious holidays and this phenomenon occurs repeatedly every year. So we need a broiler supply chain research to maintain price stability using a dynamic simulation system model of the broiler chicken supply chain in DIY. This study develops a Causal Loop Diagram (CLD) and Stock and Flow Diagram (SFD) of system dynamic model of the broiler supply chain in the DIY and simulates the model using Powersim Studio 10 software. The simulation is confirmed verified and valid, therefore for the next research model can be used to solve the problem by generating policy scenario.

Computer programs are now available in various laboratories for the indexing and simulation of transmission electron diffraction patterns. Although these programs address themselves to the solution of various aspects of the indexing and simulation process, the ultimate goal is to perform real time diffraction pattern analysis directly off of the imaging screen of the transmission electron microscope. The program to be described in this paper represents one step prior to real time analysis. It involves the combination of two programs, described in an earlier paper(l), into a single program for use on an interactive basis with a minicomputer. In our case, the minicomputer is an INTERDATA 70 equipped with a Tektronix 4010-1 graphical display terminal and hard copy unit.A simplified flow diagram of the combined program, written in Fortran IV, is shown in Figure 1. It consists of two programs INDEX and TEDP which index and simulate electron diffraction patterns respectively. The user has the option of choosing either the indexing or simulating aspects of the combined program.

Overview:   This document provides a summary of a practical method that can be used to compare handwriting (whether text-based or signatures) in the forensic environment. It is intended to serve as an approach to forensic handwriting examination for practitioners actively involved in casework, or for those interested in investigating general aspects of the practice of forensic handwriting examination (for example researchers, academics and legal professionals). The method proposed does not cover in detail all aspects of the examination of handwriting. It does, however, form the framework of forensic handwriting methodology in the government environment in Australia and New Zealand as represented by the Document Examination Specialist Advisory Group (DocSAG). It is noted from the outset that handwriting is examined using complex human perceptual and cognitive processes that can be difficult to accurately and validly describe in written form since, for the most part, these processes are hidden. What is presented here is the agreed general approach that DocSAG practitioners use in the majority of the comparisons that they carry out. The method is based around a flow diagram which structures the comparison process and provides the reader with a guide as to the significant landmark stages commonly worked through in practical handwriting examinations. Where decision points occur within the course of the method flow diagram a series of modules have been developed which describe the nature of the decision under consideration and address relevant theoretical and practical issues. Each module is, as far as is practical, independent of other modules in the method. This assists in facilitating changes in the process over time that may result from theoretical, practical or technological advances in the field. Purchase Volume 26 - Special Issue - $40

Hukum Islam merupakan seperangkat norma atau peraturan yang bersumber dari Allah SWT dan Nabi Muhammad SAW untuk mengatur tingkah laku manusia di tengah-tengah masyarakat. Aktifitas yang kian padat menjadikan sebagian orang memiliki tingkat mobilitas yang tinggi. Terkadang hal yang tidak menjadi prioritas namun suatu keharusan bagi umat muslim terlalaikan, diantaranya yaitu mengenal dan menguasai hukum Islam dengan baik dan benar menjadi terabaikan bahkan terlupakan. Faktor penyebabnya adalah terbatasnya informasi, waktu maupun media untuk belajar, untuk itu dibutuhkan suatu aplikasi yang dapat memudahkan masyarakat khususnya umat muslim untuk mempelajari hukum Islam dengan lebih efektif dan efisien. Aplikasi Ayatul Ahkam Berbasis Web dirancang dengan menggunakan data flow diagram (DFD) dan penyimpanan data menggunakan database MySQL. Rancangan database menggunakan entity relationship diagram (ERD), conceptual diagram modelling (CDM), physical diagram modelling (PDM) dan menggunakan bahasa pemrograman hypertext preprocessor (PHP) serta menggunakan algoritma stemming Porter untuk pencarian. Metode dalam pembangunan menggunakan metode prototipe.   Kata Kunci : Ayatul Ahkam, Website

Proses pengumpulan data dalam penelitian survey merupakan hal yang sangat penting. Penelitian berbasis survey membutuhkan instrumen pengumpulan data berupa kuesioner. Selama ini peneliti atau surveyor melakukan pengumpulan data secara manual yaitu dengan  mencetak kuesioner dan menyebarkannya dengan mendatangi satu persatu responden. Hal ini memakan waktu yang lama dan biaya yang besar sehingga menjadi masalah utama yang dihadapi dalam pengumpulan data dengan kuesioner. Untuk mengatasi masalah tersebut dibutuhkan suatu aplikasi yang dapat membantu surveyor dalam melakukan survey secara online. Penelitian ini bertujuan untuk  merancang dan membangun aplikasi kuesioner online berbasis web dengan meggunakan metode waterfall dengan tahapan analysis, design, implementation, testing dan maintanance. Pemodelan sistem dan basis data meggunakan Data Flow Diagram (DFD) dan Entity Relationship Diagram (ERD). Bahasa Pemrograman yang digunakan yaitu, HTML, PHP, CSS, Java Script, dan untuk databasenya menggunakan MySQL. Skala pengukuran yang digunakan dalam perancangan kuesioner menggunakan skala likert dan skala guttman. Aplikasi ini memiliki 3 hak akses yaitu, admin, surveyor dan pengunjung/responden. Dengan adanya aplikasi diharapkan ini proses pengumpulan data dengan kuesioner dapat lebih efektif dan efisien.

: Streptomyces species are very well known for the production of antimicrobials and enzymes. The objective of this review is to search for the novel Streptomyces isolated in 2018 along with their characteristics and possible antimicrobial properties. The literature search was done according to the PRISMA flow diagram where 28 research papers were eligible for the review. Data entry and analyses were performed using IBM SPSS Statistics version 25 while phylogenetic tree was constructed using Geneious Prime Software. The data on general characteristics, biochemical as well as sugar fermentation tests, 16S rRNA gene sequence similarity and DNA-DNA hybridization relatedness were extracted from the research papers and summarized in tables and figures. The biosynthesis gene cluster (BGC) was identified using ‘antibiotics and secondary metabolite analysis shell-antiSMASH’ which showed the possibility of production of new antibiotics, antifungal and antitumor substances from the 28 novel Streptomyces isolated in 2018 which would contribute to the global effort to fight against growing multidrug-resistance.
