Abstract

The Gibbs surface excess was examined by using surface tension vs. concentration curve and a new concept for the surface excess is presented based upon data from the evaporation rate of water, the activation energy of evaporation, and the BAM images for surfactant solution. As the result, the surface excess was found to concentrate not at the air/water interface but at some depth apart below the interface as bi-lamellar aggregates.

Abstract

Innovation is needed in learning to make meaningful learning, so the student constructs their ownknowledge from the learning experience of learning process. One of the innovations is to integrate Problem Based Learning model. Problem Based Learning involves students to be active in every problem. Eleven problems type in Problem Based Learning that have different solving steps, due to every student different metacognition character potential and can change by given treatment. This research is a pre-experimental design: the pretest-posttest control and experimental group design with embedded experimental design. The metacognition character data were analyzed qualitaively, whereas the average grade data were analyzed quantitatively. The analysis of metacognition character shows the different metacognition characters and on learning process there is improvement of student achievement from 14% to 84.4%.

Abstract

Changing of minimum wage policy option by the actors in 2006 is caused mainly by any change from internal aspects of policy subsystem directly, especially the change of secondary aspects of two advocacy coalition of minimum wage in South Sulawesi. This case mainly influenced from implementation the decentralization aspect where labors or group of labors have also any opportunity to involve in wage policy debate or in the forum of board of Provincial Waging. Furthermore, the Board of Manpower (Dinas Tenaga Kerja) of South Sulawesi Province which is identified as the policy broker has an important role to meet policy subsystem’s different strategies. As a result, conflict of minimum wage between labors and employers can reduce and they can act as a mediator to chooce the wage policy.Keywords: minimum wage, advocacy coalition framework

Abstract

This study aims to study the performance of phytoecdisteroids from mulberry leaves in molting stimulating of mangrove crabs. The research was carried out at the Research and Development Center for Aquaculture at the Faculty of Marine Sciences and Fisheries at Hasanuddin University, located in Bojo Village, Mallusetasi District, Barru Regency, South Sulawesi Province. Mangrove crabs (Scylla olivacea) weighing 45-55 g and carapace widths 60-65 mm were used as test animals. There were five doses of mulberry leaf extract applied through feed, namely: A) 1.1 mg / g feed, B) 1.9 mg / g feed, C) 2.7 mg / g feed, D) 3.5 mg / g feed. Crabs were kept individually in plastic boxes that are floated above the surface of the pond. During rearing, crabs are fed 3% dry fish per day which has been enriched with mulberry leaf extract. The parameters observed were ecdysteroid compounds contained in mulberry leaf extract, ecdysteroid content in hemolymph before and after application of mulberry leaf extract, and molting percentage. Identification of the ekdisteroid compounds contained in mulberry leaf extract was carried out using Thin Layer Chromatography (TLC) and Measurement of the content of ecdysteroids in crab hemolymh was carried out using Ultra Fast Liquid Chromatography (UFLC).  The results showed that the 3.5 mg dose of mulberry leaf extract / g feed gave the highest increase in ecdysteroid hemolymph, which was approximately 1760 ekdisteroid per mL hemolimph, while the dose of 1.1 mg / g feed only provided an increase of 100 ng ekdisteroid per mL hemolymph. The higher the dose of mulberry leaf extract in the feed, the higher the increase in the concentration of hemolymph ecdysteroids, but the high concentration of ecdystoid in the hemolymph does not guarantee molting.  The optimal dose of mulberry leaf extract in the feed stimulating molting was 2.4 mg / g of feed.Keywords: mulberry, phytoecdysteroid, molting, crab, aquaculture

Abstract

Tahura Pocut Meurah Intan in Aceh Besar is a nature conservation area that has various tourist attractions to be developed for ecotourism. This requires community support which is an important factor in ecotourism development. The purpose of this study was to find out the community's carrying capacity in the development of Tahura Pocut Meurah Intan ecotourism through 3 parameters, which are acceptance for visitors, participation in ecotourism development and participation in conservation. The study used descriptive method, while data was collected from questionnaires to villagers around the Tahura Pocut Meurah Intan, which are the Suka Damai Village, the Suka Mulia Village, and the Aceh Saree Village. The results showed that the community's carrying capacity for ecotourism development in the Tahura Pocut Meurah Intan in the SukaDamai Village was classified as supportive (70%) while the other two villages, the SukaMulia Village and the Aceh Saree Village were classified as very supportive (76.6%). It can be concluded that the community's carrying capacity in the development of the Tahura Pocut Meurah Intan as ecotourism area is very supportive, in terms of visitors' acceptance, community participation in ecotourism development, and community participation in conservation effort.

Abstract

Tulisan ini memaparkan hasil Penelitian yang dimaksudkan untuk memberikan salah satu solusi terhadap masalah konsumsi energi listrik bagi perangkat elektronik berdaya kecil, misalnya sensor. Smartphone yang umumnya memiliki port audio dapat mengeluarkan sinyal audio. Dengan menggunakan perangkat lunak aplikasi pembangkit sinyal, maka dapat dihasilkan berbagai macam sinyal audio pada port audio. Keluaran sinyal audio, yang salah satunya berupa sinyal sinusoida yang merupakan bentuk tegangan AC (bolak-balik), dapat diubah besar tegangannya dan selanjutnya disearahkan sehingga menghasilkan tegangan DC (searah) dengan menggunakan rangkaian penaik tegangan (voltage multiplier) dan penyearah (rectifier). Hasil yang diharapkan adalah berupa tegangan DC 5 V yang dapat digunakan sebagai catu daya bagi berbagai perangkat elektronik berdaya kecil.

Abstract

Most of the eleventh-grade students of SMAN 3 Jambi City find difficulties in understanding the concepts of Coordination Systems in Biology subject. This study aims to create a learning tools in the form of students? worksheets based on problem-based learning-flipped classroom. This study employs ADDIE Model. Validations were undertaken by learning design, material, and product design experts.  Where as, best practice validation was done by a Biology teacher teaching in SMAN 3 Jambi City. Research subject was students of SMAN 3 consisting of 3 students for individual trial and 9 students for small group trial. Data from validation results were described qualitatively. The design stage produces a worksheet prototype based on problem-based learning-flipped classroom. The development stage produces a new version of student worksheet that has been positively responded by the research participants. In implementation stage, the worksheet has been considered very good by students. In evaluation stage, the study has produced a sudent worksheet that accommodates students needs to improve their ability in transforming knowledge. Based all stages of the ADDIE, it can be concluded that the produced student worksheet is interesting, easy to use and easy to understand. It helps students to learn coordination systems more effectively. The created student worksheet can be further developped into an e-student worksheet.
