Abstract

Improving the quality of services for students from the Batusangkar IAIN Information Management Department requires a system that can provide information needed by students and graduates such as information about alumni data and alumni careers themselves. In addition, this system can also be used as a means to establish communication and manage friendship between students and alumni. This research was carried out in several stages, namely: Collecting data through field studies by observing and observing the IAIN Batusangkar's Information Management Study Program, developing the system using the waterfall method and proceeding with the process, database and interface design. One indicator of the success of the education process can be seen from the success of alumni both continuing studies at a higher level, as well as various fields of work carried out professionally, but the Department of Information Management has not been managed and organized systematically causing some alumni data to not be captured properly, resulting in the lack of information and communication between alumni and alumni. The results of this study are in the form of developing a tracking information system for alumni that contains the amount of alumni data that has worked, alumni workplaces. For this reason, it is necessary to create a system to facilitate the institution, especially the informatics management department in tracking alumni. In this research the web-based application system is designed using supporting applications such as Apache, MySQL and Macromedia Dream Weaver and the waterfall modeling method.

Abstract

Talking about West Sumatra, what will surely be drawn is tourism, it is undeniable that West Sumatra is a tourist province, one of which is island tourism, including Pamusan Island, Cubadak Island, Pasumpahan Island, Pagai Island, Siberut and others. Because it needs the support of supporting applications such as inter-island transportation ordering, it needs the support of technology, one of which is inter-island transportation and also ordering food that can be delivered directly to the address. In order to help make it easier for tourists to visit the island in West Sumatra, an application called the Go Land Application was designed. The Go Land application is an application designed using the Agile system development method with the Android Studio programming language and the UML (Unified Modeling Language) system design tool. This application has several services including: Go_Land, Land_Car, Land_Food, Land_Med, Land_Rent, Land_Auto, in this application Travelers can use facilities on the island including water games, snorkeling, seafood and can be used for formal or informal events. With this application, tourists are expected to be easier, faster and safer to enjoy island tourism in West Sumatra.

Abstract

Differential equations are one of the topics in mathematics that have many applications in mathematical modeling, for example in population growth. Population growth is an important thing that needs to be considered in order to be able to see the development of an area so that it can assist the regional government in determining the policies taken for the progress of the region related to the potential growth of the existing population. In this paper we will study population growth models with limited growth. From this model, the population of a region can be predicted in the coming year

Abstract

Infant growth is largely determined by the amount of breast milk obtained including the energy and other nutrients contained in breast milk. Breastfeeding in Indonesia has decreased, especially in West Sumatra based on Indonesia Health Profile in 2014. This study aims to determine the Influence of Exclusive Breastfeeding on the growth and development of infants aged 6-24 months in Nagari Sariak Laweh Working Area Batu Hampar Puskesmas, District Akabiluru. The measured growth consists of body weight, body length and Head Circumference. Progress was seen through KPSP (Pre-Growth Questionnaire Developments). This type of research is an observational research that is analytic with Cross-Sectional research design. Data analysis used was univariate and bivariate (Independent T test). The study period was from October 2017-February 2018. The population in the study were infants aged 6-24 months in Nagari Sariak Laweh. The sample in this study amounted to 30 babies. Data collection was done by using questionnaire and direct measurement. The statistical results show that there is no Influence of Exclusive Breastfeeding on Infant Growth (body weight, body length, head circumference) and no Influence of Exclusive Breast Feeding on Infant Development (based on KPSP questionnaire).

Abstract

Lead (Pb) is heavy metal which is naturally found in the earth's crust or originates from human activities, for example from combustion gas emissions in motorized vehicle engines. Republic of Indonesia Ministry of Health Number 1406 / MENKES / SKI / IX / 2002 concerning the examination of lead levels in human biomarker specimens human measurements of lead levels in the human body can be carried out by blood, urine and hair specimens. The purpose of this study is to determine the levels of lead metal in the urine of active smokers. The results of research on lead levels obtained on accuracy parameters, namely the accuracy test results for the method of wet destruction using HNO3 has an average recovery of 71.8% while using HNO3 added H2SO4 has an average recovery of 46.48%, precision test results are obtained % RSD method of destruction on HNO3 was 28.80%. If on HNO3 added 50.58% H2SO4, linearity test (r) 0.999, LoD value on HNO3 0.76 and on LoD HNO3 H2SO4 added. Based on the results of the study of verification of lead metal using wet digestion in the urine of active smokers not in the range of acceptability conditions it indicates that the method cannot be valid for use in the examination of lead in urine by the method of wet destruction in the active smookers.
