The purpose of this research is to develop a cooperative learning model based on local wisdom (PKBKL) of Bali (Tri Pramana's concept), for physical education, sport, and health learning in VII grade of Junior High School in Singaraja-Buleleng Bali. This research is the development research of the development design chosen refers to the development proposed by Dick and Carey. The development of model and learning devices was conducted through four stages, namely: (1) identification and needs analysis stage (2) the development of design and draft of PKBKL and RPP models, (3) testing stage (expert review, try out, and implementation). Small group try out was conducted on VII-3 grade of Undiksha Laboratory Junior High School in the academic year 2013/2014, large group try out was conducted on VIIb of Santo Paulus Junior High School Singaraja in the academic year 2014/2015, and the implementation of the model was conducted on three (3) schools namely SMPN 2 Singaraja, SMPN 3 Singaraja, and Undiksha laboratory Junior High School in the academic year 2014/2015. Data were collected using documentation, testing, non-testing, questionnaire, and observation. The data were analyzed descriptively. The findings of this research indicate that: (1) PKBKL model has met the criteria of the operation of a learning model namely: syntax, social system, principles of reaction, support system, as well as instructional and nurturing effects, (2) PKBKL model is a valid, practical, and effective model, (3) the practicality of the learning devices (RPP), is at the high category. Based on the research results, there are two things recommended: (1) in order that learning stages (syntax) of PKBKL model can be performed well, then teachers need to have an understanding of the cooperative learning model of Student Team Achievement Division (STAD) type and the concepts of scientifically approach well, (2) PKBKL model can be performed well on physical education, sport and health learning, if the teachers understand the concept of Tri Pramana, therefore if the physical education, sport and health teachers want to apply this PKBKL model, they must first learn and master the concept of Tri Pramana well. © Published under licence by IOP Publishing Ltd.

open content is a concept where the learning content can be shared freely and openly. Video lecture can be used as open content by recording any lecture in the classroom and share them through the learning management system. However, video lectures have some disadvantages, such as (a) the focus of the video cannot cover all objects in the class. (b) one lecture video has a lot of frames so that it is difficult for the students to find the desired sub-topics in the video. This article discusses how to overcome both these problems by combining video and slide into one learning content so that it can cover the weaknesses of learning videos as the main medium of learning. In addition, the developed system also allows users to use them offline so that it can be distributed to anyone who do not have internet access. © 2016 IEEE.

Learning geometry gives many benefits to students. It strengthens the development of deductive thinking and reasoning; it also provides an opportunity to improve visualisation and spatial ability. Some studies, however, have pointed out the difficulties that students encountered when learning geometry. A preliminary study by the author in Bali revealed that one of the main problems was teachers' difficulties in delivering geometry instruction. It was partly due to the lack of appropriate instructional media. Coupling with dynamic geometry software, dynamic learning environments is a promising solution to this problem. Employing GeoGebra software supported by the well-designed instructional process may result in more meaningful learning, and consequently, students are motivated to engage in the learning process more deeply and actively. In this paper, we provide some examples of GeoGebra-aided learning activities that allow students to interactively explore and investigate geometry concepts and the properties of geometry objects. Thus, it is expected that such learning environment will enhance students' internalisation process of geometry concepts. © Published under licence by IOP Publishing Ltd.

The objective of this third year study was to describe the result of the effectiveness testing in the field aided by mobile technology to the draft of dictionary of loan words in Balinese that has been successfully validated by linguists and lexicologists in the second year. This study was designed by following the stages of thinking in research and development adapted from the development of a set of teaching materials using 4-D model (Define, Design, Develop, and Disseminate). The subjects for this third year were Balinese language teachers and the students of Balinese Language Department in the public as well as in private institutes of higher learning in Singaraja and Denpasar. The data were collected through questionnaire The data that had been collected were analyzed by using a descriptive analysis Based on the formulation of the problems in this third year research and data analysis that has successfully been done it can be concluded that quantitatively, the draft of dictionary of loan words in Balinese can be said to be effective since the mean score obtained was 3.6 (falling into effective category). However, qualitatively, there are reasonably many inputs given by the respondents for the purpose of improving the draft of the dictionary. The inputs given are related to the aspects of (1) the appearance, (2) the title of the dictionary, (3) the foreword, (4) the guide to the use of the dictionary, (5) the quality of the contents of the dictionary and (6) bibliography. © 2005 – ongoing JATIT & LLS.

Through the use of information technology, the students no longer find it difficult to look for sources/learning materials, interact and discuss with each other any time and any where they are. One form of the roles of information technology which can facilitate students in individual learning, group learning and learning together with the teacher in the classroom and outside of the classroom is blended learning. The fact in schools shows that not all of the learning process can be optimized by using blended learning. Therefore, there is a need to evaluate comprehensively any time and any where they are (evaluators). For this purpose, the appropriate evaluation model to be used is mobile phone-based CIPP. By using this model, then the evaluator can study evaluating the use of blended learning overall through of the context, input, process and product that will be able to provide appropriate recommendations for the improvement of the learning process using blended learning in school.

The development of the automotive industry brings impact of increasing use of aluminum for vehicle components that will ultimately produce more aluminum waste. If it is not addressed properly, it will be a serious problem for the environment. One of the solutions is to recycle the waste of drum brake to be a raw material for motorcycle accessories brake handle. The process of making motorcycle brake handle using the sand casting method can be done by varying the temperatures of casting molten metal which are at temperatures of 650°C, 700°C and 750°C. Furthermore, the testing of the mechanical properties and microstructure of the resulted product is done. The result shows that motorcycle brake handle required high impact strength in which the highest impact strength was 0.011 Nm/mm2 that was obtained when temperature of casting was 700°C. © 2016 Trans Tech Publications, Switzerland.

Seawater circulation in permeable coastal sediments is driven by tidal changes in hydraulic gradients. The resulting submarine groundwater discharge is a source of nutrients and dissolved organic matter (DOM) to the water column. Yet, little is known about the cycling of DOM within tidal sediments, because the molecular DOM characterization remains analytically challenging. One technique that can dissect the multitude of molecules in DOM is ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). To aim at a high resolution DOM analysis we study the seasonal turnover and marine and terrestrial sources of DOM in an intertidal creek bank of the southern North Sea down to 3m depth and link the biogeochemical processes to FT-ICR-MS data and the analyses of inorganic porewater chemistry, δ13C of solid-phase extracted dissolved organic carbon (SPE-DOC), dissolved black carbon (DBC) and dissolved carbohydrates (DCHO). Increasing concentrations of dissolved Fe, Mn, P, total alkalinity, dissolved nitrogen, DOC and a concomitant decrease of sulfate along the seawater circulation path from the upper tidal flat to the tidal flat margin indicate continuous microbial activity. The relative increase of Si concentrations, unsaturated aliphatics, peptide molecular formulae and isotopically more 13C-enriched SPE-DOC towards the tidal flat margin suggests that remineralization processes mobilize DOM from buried algal (diatoms) and microbial biomass. Porewater in sediments <100cm depth contains 13C-depleted SPE-DOC and highly unsaturated compounds which are probably derived from eroded peats, suggesting rapid removal of bioavailable marine DOM such as DCHO from the water column and selective enrichment of terrestrial DOM. DBC concentrations are highest in the discharging porewater close to the tidal creek suggesting that the intertidal flat is an important DBC source to the coastal ocean. Porewater DOM accumulating at the low water line is enriched in N and S. We hypothesize that this is partly due to DOM reacting with dissolved sulfide and ammonium which may increase the refractory character of the DOM, hence making it less bioavailable for in situ active microbes. © 2014 Elsevier Ltd.

Various methods of solid waste treatment are available. However, due to heterogeneity characteristic of solid waste, determined the best means to manage solid waste in environmental view of point is not straightforward. In this case, solid waste management scenarios and an environmental analysis tool are required. This study compared various energetic valorization options with each other using the simplified Life Cycle Assessment (LCA) methodology. These scenarios were landfilling without energy recovery as a representative of existing solid waste management, landfilling with energy recovery, combination of incineration and anaerobic digestion, combination of gasification and anaerobic digestion, direct incineration, and direct gasification. A case study area in a typical KARTAMANTUL (acronym of three cities: Yogyakarta, Sleman, Bantul) intercity region in province of Yogyakarta, Indonesia. One ton of solid waste treated was defined as the functional unit of the systems studied. The Life Cycle Inventory (LCI) analysis was done by including field and laboratory survey to characterize solid waste in area study and using emission factors which were adopted from literature to estimate environmental burdens for each scenario. Inventory's result was classified into impact categories, i.e. global warming, acidification, eutrophication, and photochemical oxidant formation. The indicators of categories were quantified by using the equivalence factors of relevant emissions to determine the environmental performance of each scenario. The study shown that in most of the impact categories (except acidification), a scenario with direct gasification indicated the best environmental profile. A sensitivity analysis was also conducted to examine change in outcomes for a variety of organic biowaste inputs, but had no significant effect on the overall result. © 2011 Elsevier Ltd.
