Learning subject matter through English as the medium of instruction: students’ and teachers’ perspectives

Abstract: Many policy-makers are in favor of Content Language and Integrated Learning (CLIL) for this approach integrates both language and content. In Indonesia, CLIL is locally known as English as a medium of instruction (EMI) where content subjects are taught in English. This present study presents the results of implementing an EMI policy in a large college in Indonesia, a semester after the start of the implementation. The main objectives of the study were to seek the views of both the students and teachers regarding the use of EMI. Questionnaires, classroom observations, and interviews were used as the research instruments. The findings suggest that both students and teachers acknowledge the important role of English in the world. However, both reported a host of problems with the implementation of EMI. In this paper, I would also suggest ways to deal with these from both institutional and curricular perspectives.

Physical violence detection for preventing school bullying

Abstract: School bullying is a serious problem among teenagers, causing depression, dropping out of school, or even suicide. It is thus important to develop antibullying methods. This paper proposes a physical bullying detection method based on activity recognition. The architecture of the physical violence detection system is described, and a Fuzzy Multithreshold classifier is developed to detect physical bullying behaviour, including pushing, hitting, and shaking. Importantly, the application has the capability of distinguishing these types of behaviour from such everyday activities as running, walking, falling, or doing push-ups. To accomplish this, the method uses acceleration and gyro signals. Experimental data were gathered by role playing school bullying scenarios and by doing daily-life activities. The simulations achieved an average classification accuracy of 92%, which is a promising result for smartphone-based detection of physical bullying.

Integration of Theory of Planned Behavior and Norm Activation Model on Student Behavior Model Using Cars for Traveling to Campus

Abstract: Although there are clear environmental, economic, and social drawbacks in using private vehicles, students still choose cars to get to campus. This study reports an investigation of psychological factors influencing this behavior from the perspective of the Theory of Planned Behavior and Norm Activation Model. Students from three different university campuses in Surabaya, Indonesia, (n = 312) completed a survey on their car commuting behavior. Results indicated that perceived behavioral control and personal norm were the strongest factors that influence behavioral intention. Attitude, subjective norm, perceived behavioral control, and personal norm explain 62.7% variance of the behavioral intention. In turn, behavioral intention explains 42.5% of the variance of the actual car use. Implications of these findings are that in order to alter the use of car, university should implement both structural and psychological interventions. Effective interventions should be designed to raise the awareness of negative aspects of car use.

Using information and communication technology (ict) to enhance language teaching & learning: an interview with dr. a. gumawang jati

Abstract: In recent years, information and communication technology (ICT) has become embedded and affected the every aspect of our lives. Rapid development of ICT has changed our language teaching pedagogy at all levels. Teachers, curriculum developers, researchers have been constantly striving to find techniques to use some form of it to both assist and enhance language learning. What is more exciting is that studies have demonstrated positive effects that ICT brings towards students' learning motivation (Chenoweth, Ushida & Murday, 2006; Stepp- Greany, 2002), students' personal needs and learning styles (Gimenez, 2000), students' language mastery (Stepp-Greany, 2002), effective teaching and learning process (Al-Jarf, 2004), etc. Although these studies have shown that ICT has the potential important role in supporting and enhancing language learning, the use of ICT should never be the goal in and of itself. The responsibility for language instruction should be in the hands of qualified teachers who have the knowledge and expertise to manage and to make the best use of it to accomplish learning objectives.

Effect of Particle Size on Properties of Sidoarjo Mud-Based Geopolymer

Abstract: The eruption of Sidoarjo mud volcano that has been taken place since 2006 had caused significant damage to the local social environment, and until now there is no immediate solution that can be offered. Utilization of the Sidoarjo mud as construction material recently has gained some advancement by calcination of the mud, that make the previously inert material to become more reactive and to be more viable for its use as cement replacement or geopolymer precursor. This paper reports an on-going study to utilize the Sidoarjo mud as precursor of geopolymer by investigating the influence of particle size on the reactivity of the calcined Sidoarjo mud. Furthermore, durability properties of Sidoarjo mud-based geopolymer was also studied. The results show that making finer the mud particles by milling in longer period, using a rod-mill drum for 8 hours, can increase the reactivity of the mud. Compressive strength of geopolymer mortar can increase up to 155% when compared to the ones based on milling time of only 2 hours. Durability properties of sulphate acid resistance and chloride penetration are comparable to fly ash-based geopolymer, while the shrinkage measurement showing higher value.

Stackelberg game for two-level supply chain with price markdown option

Abstract: Vendor–retailer collaboration has an important role in supply chain management. Although vendor–retailer collaboration results in better supply chain profit, collaboration is difficult to realize. This is because most vendors and retailers try to optimize their own profit. This paper applies the Stackelberg game with stochastic demand for the vendor–retailer system. The vendor as a leader determines the product price, and the retailer decides order quantity and frequency of price markdown. This study develops example and sensitivity analyses to illustrate the theory. Results show that the price markdown option has a better total supply chain profit than without a price markdown policy, and the vendor receives more benefit. For different demand variances, the retailer profit is more sensitive than the vendor profit.

Remanufacturing of Short Life-cycle Products

Abstract: Rapid development and innovation in science and technology have resulted in shorter product life-cycle, especially in technology-based commodities like mobile phones and computers. Mounting wastes from such products have received increasing attentions from government, society, as well as industries for sustainability concerns. Numerous studies on remanufacturing have been found on durable goods, but only a few focusing on short life-cycle products. Even though several studies implied that successful remanufacturing requires products to have long useful life and stable technology, there are other findings that support remanufacturing of short lifecycle products. It is our intention to investigate remanufacturing of short life-cycle product. A literature review is conducted to study the pros and cons, life-cycle implication, and remanufacturing aspects of short life-cycle products. Then we propose a framework that can be used to decide and plan the remanufacturing system. Furthermore, we conduct a survey to obtain descriptive analysis about the market potential for remanufactured short life-cycle products. The factors investigated are existence of demand, customer’s willingness to pay (WTP), and existence of green segment. The survey results show that low-end customers are the potential market segment for short life-cycle remanufactured product, because they have the highest preference toward remanufacturing and 95% of them chose remanufactured product when the price is less than 40% of new product. It is also shown that green segment exists since 42%, 65%, and 47% of customers from high-end, low-end, and student subgroup respectively consider buying remanufactured products over new ones driven by their concern for the environment.

Behavior of Flame Propagation in Biogas Spark Ignited Premix Combustion with Carbon Dioxide Inhibitor

Abstract: Biogas is a mixture of gases which commonly consists of methane (up to 50%) and other inhibitor gases which are dominated by carbon dioxide (up to 50%). Biogas is produced naturally by the decomposition of organic materials such as vegetation or animal manure in the absence of oxygen and it also contributes less greenhouse gases which may lead to global warming or climate change. The presence of carbon dioxide (CO2) in biogas is presumed to have some effects on biogas flame propagation characteristics. This study focuses on the effect of carbon dioxide (CO2) as the biggest inhibitor composition in biogas on flame propagation speed as the important flame propagation characteristic in spark ignited premix combustion. Propagating flames are employed to measure the flame propagation speed as a function of the mixture composition. This parameter was measured using a transparent tube fuel chamber with dimensions of 60 mm inner diameter and 300 mm height based on DIN 51649 standards and recorded by high speed digital photographic technique. The characteristic of biogas-oxygen flames were studied at stoichiometric, room temperature and atmospheric condition from 0% to 50% CO2 biogas inhibitor composition increased by 10% for each experiment. The results showed that the carbon dioxide decreases flame propagation speed of biogas. These indicated that carbon dioxide reduced reaction rate of biogas premixed combustion.

Fuzzy Logic Reliability Centered Maintenance

Abstract: Reliability Centered Maintenence (RCM) is a systematic maintenence strategy based on system reliability. Application of RCM process will not always come out with a binary output of “yes” and “no”. Most of the time they are not supported with available detail information to calculate system reliability. The fuzzy logic method attempts to eliminate the uncertainty by providing “truth” in different degrees.Data and responses from maintenance department will be processed using the two methods (reliability centered maintenance and fuzzy logic) to design maintenance strategy for the company. The results of the fuzzy logic RCM application are maintenance strategy which fit with current and future condition.

Analysis of the impact of information technology investments-a survey of indonesian universities

Abstract: In recent years, the utilization of information technology has been magnificently increased in service industries, particularly, education institution, which by using Information Technology related products such as academic information system and learning management system. In Indonesia, universities invest enormous resources in information technology (IT), with little evidence of the latter’s effectiveness. Stakeholders struggle with gauging how effective or ineffective making these investments truly is, given the lack of instruments of measurement by which to establish, for instance, an internal rate of return or a period of recovery on investments. This paper investigates the impact of investment in information technology on the return on assets (ROA) of selected private universities in Indonesia for the period 2008 2014 using Adapted Information Economics. By using this method, it is possible to implement into other university. Primary and secondary data were collected during this research. The study recommends that universities should increase investments in software, hardware and infrastructure which will enhance their Management Information System and profitability.

Neuro-fuzzy architecture of the 3d model of massive parallel actuators

Abstract: This paper reports the effective control mechanism of the discrete state manipulators (DSMs) with six degree of freedom (DOF). The DSMs are special kind of robot manipulator with massive actuators that can be switched among limited number of discrete states. We introduce ternary-DSMs (t-DSMs) manipulators which controlled by force and have continuous motions that commanded through only three discrete states. The main problem of this mechanism is how to design a real-time controller which is efficient and fast for solving its inverse static problem (ISP). Precisely, a computational intelligence method based on neuro-fuzzy method is suggested to find the optimal training computation, which is measured by the root mean squared error of ISP. The architecture of t-DSMs featuring three-state force pneumatic actuators and six-DOF. For instance, a neuro-fuzzy method for t-DSMs constructs IF-THEN rules from fuzzy relations among inputs and outputs in the training mechanism (inputs: position and force; outputs: three-state). After related model is found in the training phase, the architecture can be used to determine outputs of the network from given inputs with similar accuracy in the testing phase. The paper proposed an architecture which is based on the Neuro-Fuzzy Takagi Sugeno (NFTS) inference scheme with Gaussian membership functions. The structure is with multivariate input and multistate outputs, such as positions and forces as input NFTS networks and the three-state of the actuators as output networks. The learning of the network uses an extended LMA version with optimal training parameters. The training algorithm needs at least one million iterations with different membership functions; employ around 17% of the input-output correspondences dataset from the known input and output. For training database, the NFTS model generates 124 dataset from the 729 possible dataset. The optimized membership function (M) after one week searching time using optimized search procedure using M from 4 to 15 for the 6-DOF model of 6-ternary DSMs. Regarding model performances for the ISP solution, the NFTS with M=9 features better root mean squared error results compared to the others.

Potentials of LUSI Volcanic Mud as Construction Materials

Abstract: This year of 2014 is marked as the eight anniversary of Sidoarjo or LUSI volcanic mud eruption. More than 640 hectares of productive land has been submerged, and yet the eruption is still continue. This paper reviews the search to uncover its potential as construction materials. The mud is in semi-crystalline state in its original form, and it is rich in silicon and aluminium oxides, with the total amount of SiO2, Al2O3 and Fe2O3 is more than 80%. Calcination at 600-8000C for a certain period of time, followed with grinding to reduce the particle size to less than 63μm convert the mud to be an amorphous and reactive material. The treated mud is an excellent pozzolanic material, suitable for making high volume pozzolanic mortar or concrete. At the same time, it is a strong candidate for precursor of geopolymer material.

Stereotyping risma : pembingkaian sosok tri rismaharini di majalah detik dan tempo

Abstract: Saat ini, dunia politik dan pemerintahan tidak hanya menjadi milik laki – laki, tapi juga perempuan. Banyak perempuan yang terjun ke dalam dunia politik, menjadi politisi, atau bahkan pemimpin pemerintahan. Namun, stereotip yang merujuk pada keraguan publik masih ada. Perempuan dianggap tidak cocok menjadi pemimpin pemerintahan karena dianggap tidak mampu dan feminin. Media massa juga berperan dalam pengukuhan anggapan tersebut. Penelitian ini bertujuan untuk melihat bagaimana media massa, memberitakan atau membingkai sosok pemimpin perempuan, yakni Tri Rismaharini (Walikota Surabaya). Majalah Digital Detik menerbitkan edisi “Risma Super Wali”, sedangkan Majalah Tempo menerbitkan edisi “Bukan Bupati Biasa”. Setelah dianalisis dengan perangkat framing Pan – Kosicki (sintaksis, skrip, tematik, dan retoris), peneliti menemukan masih adanya stereotip berbau gender pada berita – berita tentang sosok Risma, yakni feminin, domestik, emosional, dan tidak memiliki kemampuan politik. Sifat feminin dan emosional Risma terlihat dari berita tentang kepeduliannya kepada warganya dan kecenderungannya menggunakan hati saat bekerja. Adapun sifat domestik Risma terlihat dari berita mengenai kinerjanya dalam merawat dan menjaga kebersihan serta taman – taman di Surabaya. Terakhir, penjelasan mengenai ketidakmampuan Risma dalam hal politik memperkuat stereotip gender bahwa perempuan tidak pantas menjadi pemimpin pemerintahan.

Extreme Rainfall Indices for Tropical Monsoon Countries in Southeast Asia

Abstract: Southeast Asian countries have the possibility to have rainfall and number of extreme rainfall event change due to future climate variation. This paper proposed three extreme rainfall indices as a modification of climate extremes indices from CLIMDEX Project by researchers at the Climate Change Research Centre (CCRC), the University of New South Wales (UNSW). The proposed indices aim to be used as a parameter for observing extreme rainfall events in tropical monsoon countries. Eleven extreme precipitation indices from CLIMDEX Project and the three proposed extreme precipitation for tropical monsoon countries are systematically analyzed based on data of daily rainfall from meteorological stations in Bangkok and Jakarta. Mann-Kendall test was used to observe the trend of extreme rainfall. In general, the analysis of a total of 14 extreme indices show both Bangkok and Jakarta received more rainfall during rainy season and less rainfall during dry season. Specifically, a significant increasing trend of extreme rainfall indices (R60 and R80) was revealed using the proposed indices.
