Abstract

The research was conducted on the linearity of the output radiation in the mobile X-ray by using Piranha. This study aimed to measure the radiation dose exposure, to determine the relationship between the increase in the voltage of the radiation dose exposure and increase the tube current to the radiation dose exposure, as well as to analyze the radiation output and linearity of the output radiation. Data collection was conducted at the Dr. Tadjuddin Chalid Hospital Makassar in radiological installation. In this study the variables that measured the radiation dose and exposure variables that change the tube current and voltage. The data obtained and analyzed to calculate the value of the output radiation and radiation output linearity in the X- ray mobile. The analysis showed that the X-ray mobile with GE brand that are in radiological installation Dr. Tadjuddin Chalid Hospital has good linearity.

Abstract

A research has been done on the dye components from the extract of red pepper (Capsiccum annum L) which is potentially used as photosensitizer. This study aims to determine the efficiency and the characteristics of the dye. The efficiency is measured on a cell made of glass ITO 100 Ω and a technical semiconductor TiO2. The pepper extract obtained from the ultrasonic maceration by methanol which then purified using a chromatography column using the ratio of 1: 4, 1: 1 and 4: 1 methanol:n-hexane. The results showed that the efficiency of the crude extract, fraction by ratio of 1:4; 1: 1 and 4: 1 are respectively 0.027%, 0.012%, 0.013% and 0.034%. Subsequently, the best efficiency fraction was characterized by using FTIR, UV-Vis and GC-MS. The wavelength of visible light obtained at 466 and 443 nm which is corresponds to the wavelength of carotene. The components indicate absorption  at 1631.78 cm-1, 3008.95 cm-1 and 2992 cm-1 that are characteristic of carotenoid whereas, that of 1739 cm-1 and 3446.79 cm-1  are carbonyl and hydroxyl group of xantofil. According to the GC-MS fragmentation pattern, the carotenoid compounds identified by mass abundace at 91 and 105.

Abstract

The research was conducted by taking a sample of 25 pieces of cell phone. Mobile radiation intensity measured electromagnetic waves are receiving phone calls. Measurements were made by placing two headphone in a different room with a range of ± 20 meters. Tool used to measure the intensity of radiation of electromagnetic waves emitted by mobile phone radiation is a measure C32-QX5. Values were collected before phone calls and performed on two conditions after receiving the phone call is a normal condition and the condition of the loudspeaker. The purpose of this study was to determine the intensity of the electromagnetic radiation emitted by mobile phones with different brands and types and determine their effects on health. Results showed that all cell phones that have measured the intensity of the radiation was still safe to use because it has an average radiation intensity 6 mW/cm2, which limits the intensity of radiation that can be tolerated by the body is equal to 10 mW/cm2. The use of mobile phones continuously for one hour a day in the ten-year timeframe, estimated the value of the intensity of radiation received by the body tissue will exceed safe limits.

Abstract

The purpose of this article was to provide the understanding of the performance of family firms, explain the relationship of family ownership and family involvement in management and the performance of firms, and to show the differences in the performance of family firms and non- family firms. The analysis carried out based on the results of the review of 29 articles published in the international journals. The selected article is an article that proves the role of family ownership and family involvement in management as a monitoring of firms in order to increase the performance of firms. The results of the literature review found that family ownership and family involvement in management improved the performance of firms. Small scale firms, middle scale firms, and young company positively contributed to the performance of firms. The performance of family firms was better than the performance of non–family firms.

Abstract

ABSTRACTVascular plants have contain some microbes, one of them is endophytic fungi. Endophytic fungi is microorganisms present in the plant organs such as seeds, leaves, flowers, twigs, stems and roots. White pomegranate is one of vascular plants associated with endophytic fungi. White pomegranate contains many benefits in it, among others, as an antimicrobial. Endophytic fungi present in plant tissue to produce the same compound with  host. The aim of the study is to determine the type of endophytic fungi in the peel of pomegranate and know the different types of endophytic fungi on three levels of fruit maturity The study conducted in February until May 2016 in biology Laboratory of educational Faculty, Syiah Kuala University. The approach that is used in this study is a qualitative approach with descriptive type. The data collection is conducted by several stages of sampling, media preparation, isolation of fungi and fungal identification. Based on the analysis of data, result of the study are: endophytic fungus found in the peel of pomegranate divided into seven types of fungi, they are Penicillium sp.1, Penicillium sp.2, Aspergillus sp.1, Aspergillus sp.2, Aspergillus sp.3, Phytium sp, and fungi can not be identified. There are different types of endophytic fungi on three levels of maturity of pomegranate are young, middle-aged and elderly, but there was one type of fungus that was on the third level of maturity pomegranate is Penicillium sp.1Key words: endophytic fungi, peel of white pomegranate, identification

Abstract

Endophytic fungi that live on plant tissue has the potential to produce secondary metabolites, same as its host. This study aimed to identify the types of endophytic fungi found in leaves of Jamblang (Syzygium cumini L.). This study used a qualitative approach and exploration and experimentation method. The sample used in this research was leaves of Jamblang from Ujongbatee, Mesjid Raya sub-district, Aceh Besar. The data were collected with some procedures: (1) isolation using sterilization surface method and (2) identification of endophytic fungi conventionally  by observing microscopic and macroscopic morphological phenotypic characters then compared with the monograph. The results showed that endophytic fungi isolated from leaves of Jamblang as many as 11 species have been identified and were as much as 7 types and were grouped into 7 genus: Fusarium, Macrophopmina, Dactylella, Paecilomyces, Nigrospora, Acremonium and Colleotrichum. The types of endophytic fungi that found on immature leaves were Fusarium sp., Isolate I, Paecilomyces sp., Isolate III, Macrophomina sp., and Acremonium sp. Fusarium sp., Macrophomina sp., Paecilomyces sp., Isolate I, and Isolates II have been found in the middle-mature leaves. While in mature leaves, Dactyela sp., Fusarium sp., Nigrospora sp., Acremonium sp., and Colletotrichum sp., Isolate I, Isolate III and IV Isolates were found. Key words: isolation, identification, endophytic fungi, leaves of jamblang

Abstract

The aim of this is to analyze the investment behavior of Acehnese entrepreneurs by considering the individual characteristics of entrepreneurs. This study was analyzed using a quantitative descriptive approach. The number of samples was 150 Aceh Entrepreneurs in 10 districts/cities in Aceh. The selected entrepreneurs who have been designated as Taxable Entrepreneurs (PKP) by the Directorate General of Taxes. The sampling technique used is judgment sampling. The research data collected by using a closed questionnaire. The results of the study show that Acehnese entrepreneurs have risk-averse behavior in making investment decisions. The results of the study also show that Acehnese entrepreneurs consider investments by sharia principles. Entrepreneurs with an older age tend to have alternative investments in financial assets. Factors of saturation and reliability cause this tendency. Older entrepreneurs are becoming increasingly uncomfortable with the business they are running right now, but they are worried about the significant risks of diversifying investment into financial assets. Education needs to be given about investing in the financial sector for Acehnese entrepreneurs, especially for older entrepreneurs.
