Abstract. Bromelain is a proteolytic enzyme from Bromeliaceae plants that can be found in pineapple (Ananas comosus (L.) Merryl). Bromelain has activity as a pharmaceutical and food. The aim of this study was to determine the bromelain content from stem bromelain extract (SBM). The stem of pineapple was extracted using a grater and then concentrated by a freeze dryer to obtain a pure concentrate. SDS-PAGE, Bradford assay and protease specific activity was used to analyze bromelain activity. The results of this study showed that bromelain from pineapple stem has a molecular weight between 19-22 kDa. Bradford assay showed 0.476 μg/mL bromelain concentration. Bromelain activity of Non freeze dried (NF) extract showed 0.317 U/mL, while freeze dried (F) extract showed 0.212 U/mL. This study concluded that the pineapple stem has bromelain activity.

Keywords: Bromelain, pineapple, proteolytic enzyme

INTRODUCTION

In industry, pineapple is a fruit with considerable waste. Waste from pineapple fruit such as leaves, stems and skin are usually only used as animal feed. However, pineapple fruit waste can be optimized for reuse because it contains complete and quite high nutrition, such as protein, minerals, fats, carbohydrates, vitamins and bromelain.1

Bromelain is a major sulfhydryl proteolytic enzyme found in pineapple plants (Ananas comosus (L.) Merryl). Bromelain is usually found in the fruit and stem, but also easy to find in small amounts in leaf, skin, core, etc.2 Bromelain from stem is known as stem bromelain (SBM). SBM has a uniqueness content compared with bromelain from fruit (FBM) because SBM contains many mixtures of various types of thiol-endopeptidases.3 Based on the research of Heinecke and Gortner, SBM concentrations are better than FBM. 4

Bromelain has been reported to have medical efficacy. Bromelain has been used traditionally to relieve tense muscles, inflammation and connective tissue. In recent years, bromelain has been used as an anti-inflammatory, antiedematous and antithrombotic agent (preventing blood clotting). In addition, bromelain showed activity to prevent lung metastases and potentially as an anticancer agent.5

The development methods for proteinase assay and enzyme activity are important to standardize bromelain to be a therapeutic product in the future.6 The objective of this study was to determine the SBM activity from Ananas comosus (L.) Merryl.

Abstract. This study aims to get a profile of the cognitive structure of pre-service-teacher students in Indonesia, on the concept of a circulatory system with Free Word Association Test instruments and The Drawing-Writing Technique. The results of the circulatory system material content analysis found that the conceptual category of "structure and morphology of circulatory devices" has the most responses, while the concept of "circulated material," has a low response. Based on the analysis results, 12 categories of the cognitive structure are obtained, in which seven categories are obtained from the Drawing Technique and 11categories obtained from the Writing Technique, and the cognitive structure of pre-service-teacher students, are at levels 2 and 3.

Keyword: circulatory system, circulated material, cognitive structure.

INTRODUCTION

How students can configure the information obtained in mind, is very interesting to investigate. Through the cognitive structure, the configuration of the relationship between concepts in long-term memory can be seen.1 There are two main components of the cognitive structure, which are information units and the organizing of information units.1,2 The arrangement and incorporation of the concepts of information units in learning into a whole cognitive structure are essential to form complete information in mind.3 The effectiveness of students in building a hierarchy of cognitive structures profoundly determines the success of learning. This structure has individual and hierarchical features.4

In the process of learning the circulatory system, it, of course, is not only about knowing the concepts and the definition of the concepts, but also requires the students’ ability to connect the concepts into a unified whole.5 The material of the circulatory system is one of the hardest materials to comprehend, especially the concept of "Blood".6

The concept of the circulatory system is an essential concept in life processes that underlie the overall function of living organizations.7 Students have different concept alternatives to the circulatory system. The alternative concept to the circulatory system for high school students is the open and closed circulation, the structure and work of heart, the blood vessels, blood and its cells, and blood pressure.8 While for nursing students, there is also a separate concept related to the blood circulation sythe stthe em, which is a blood donor.9 Teachers asthe ithe nstructors also have alternative concepts of blood circulation system, i.e., blood flow, blood pressure, and vessel diameter10 and that undergraduate students have alternative concepts about the functions of heart and blood vessels.11

Based on the above literature, the concepts associated with the circulatory system varies considerably. The emergence of variations on the concept of the circulatory system is associated with the students’ level in

Abstract The current measurement of development only considers the achievement of each dimension of development,making it difficult to analyze the success level of sustainable development models. This study provides a developmentmeasure based on social, economic and environmental factors for a composite index of development. This compositeindex was developed by the Organization for Economic Cooperation and Development. After undergoing a reductionprocess using factor analysis, 16 variables were obtained, which can be used to determine the index of sustainabledevelopment. The 16 variables selected form three factors, namely social-economic-environment; economic-environment;and social-economic factors. Social-environment has been indicated as a weak point, enhanced sustainable developmentin Indonesia doesn’t run smoothly. In the future, it is necessary to develop an environmental education curriculum, sothat it can create an environmentally conscious culture.

Keywords: Development, social, economy, education, environment, social.

INTRODUCTION

Each country undertakes a development process that essentially aims to improve community welfare.Development is expected to enhance the standard of living not only in the form of income generation, but also interms of added employment opportunities, educational improvement and increased attention to cultural andhumanitarian values.1 In addition to these economic and social approaches, a development approach must considerthe environment in order to create a balance, intergenerational justice, known as sustainable development. TheWorld Commission on Environment and Development defines sustainable development as progress that seeks tomeet current necessities without diminishing the ability of future generations to meet their needs.

Development is currently measured through the developmental achievements of each dimension, which partiallymakes the analysis of sustainable development levels among regions difficult. A good achievement in onedimension may not necessarily be followed by another dimension, such as the trade-offs created between economicand environmental dimensions. Economic development that does not pay attention to the capacity of naturalresources and the environment will cause problems in future development.2

Indonesia’s economic development shows good results. According to the International Monetary Fund MissionChief for Indonesia Luis E. Breuer, Indonesia is one of the best performing economies in 2015.2 This is marked bythe achievement of relatively high economic growth, targeted inflation and decrease in the current account deficit.Additionally, according to the 2016 Asian Development Outlook (ADO) report by the Asian Development Bank(ADB), Indonesia will lead the economic growth in Southeast Asia, which is expected to grow stronger along withan increase to 4.8 percent output in 2017 from 4.4 percent in 2014.3

However, economic progress is not necessarily followed by environmental and social improvements in Indonesia.The continuous growth of industrial sectors, motor vehicles and energy consumption increases environmental

Abstract. Methyl tert-butyl ether (MTBE) is a major toxic pollutant that contaminates inhalable particulate matter (PM10). It is an anti-knocking reagent that is generated from incomplete combustion of gasoline. Microorganisms contaminating PM10 from city areas were screened and identified. The samples were collected by cyclone size-selective sampling from Pracha U Tid road, Charoen Krung Road, Klong Toei road, Sukumvit road, Rungsit road and Pratunum, Siam and Victory Monument areas of Bangkok, Thailand, which frequently experience heavy traffic. Two species of bacteria close to Acinetobacter calcoaceticus strain PVAS6 and Bacillus cereus strain BAB-806 were found in PM10. Therefore, these two species obtained from PM10 contaminated areas were used to study MTBE removal compared to Bacillus megaterium, a VOC removal bacteria. The results showed that at an initial MTBE concentration of 250 ppm, B. cereus strain BAB-806 had higher MTBE removal (60% removal) than B. megaterium (54% removal) and A. calcoaceticus strain PVAS6 (51% removal). Although, B. cereus strain BAB-806 had higher MTBE removal, this strain is a pathogenic bacterium. Therefore, B. megaterium, a non-pathogenic bacterium, is favorable for application at real sites.

Keywords: Bacteria, contamination, MTBE, removal.

INTRODUCTION

Particle pollution or particulate matter (PM) is a complex mixture of microscopic particles and toxic gases that are emitted into the ambient air. PM10 refers to inhalable particles with a diameter of ≤ 10 μm. These particles can get deep into the lungs, bloodstream and heart, thereby causing severe health effects. Particles that contain toxic pollutants and microorganisms pose more significant risks as they increase the harmful effects on human health. 1 One toxic pollutant that can be generated from gasoline and contaminate the environment is methyl tert-butyl ether or MTBE.2 MTBE is an anti-knocking reagent generated from incomplete combustion of gasoline in vehicles. Especially near the roadside, the amount of pollution that could be attributed to the surrounding areas depends on the wind direction and geography of that area.3,4 This pollution can affect the people living around these areas. The American Conference of Governmental Industrial Hygienists (ACGIH) limited the acceptable exposure of MTBE to approximately 50 ppm or 144 mg/m3 by time-weighted average (TWA).2,5,6 The number of cars is increasing continuously, which leads to increasing numbers of pollutants emitted into the ambient air.7 Sampling areas utilized
