Atribut destinasi sebagai pesan komunikasi pariwisata: dari pariwisata untuk komunikasi
Abstrak

Reputasi Indonesia sebagai destinasi pariwisata sudah diakui oleh dunia internasional. Namun jumlah wisatawan asing yang berkunjung ke Indonesia masih jauh tertinggal dibanding pencapaian negara-negara destinasi lain, bahkan di ASEAN sekalipun. Untuk mengejar ketertinggalannya, pariwisata Indonesia perlu dikomunikasikan dengan baik. Pesan komunikasi pariwisata haruslah dirancang secara cermat, yaitu dengan menampilkan atribut destinasi yang tepat. Penelitian ini bertujuan untuk mengindentifikasi atribut destinasi utama yang menjadi perhatian dan daya tarik wisatawan ke Indonesia. Hasil penelitian ini diharapkan dapat memberikan kontribusi dalam pengembangan strategi komunikasi pariwisata Indonesia ke mancanegara. Pengambilan data dilakukan dengan menyebarkan kuesioner melalui internet untuk memungkinkan menjangkau responden dengan karakter geografis tinggal di luar Indonesia. Pengelolaan data dilakukan dengan pendekatan kuantitatif, multiple discriminant analysis, dengan populasi data wisatawan mancanegara. Hasil penelitian menunjukkan bahwa wisatawan asing menetapkan atribut safety dan securityphysiography, dan budaya sebagai tiga atribut utama dari destinasi Indonesia yang paling diperhatikan. Ketiga atribut tersebut masing-masing memiliki indikator yang saling mendukung untuk mengindentifikasi preferibilitas atribut destinasi Indonesia.

Kata kunci: Komunikasi Pariwisata, Strategi Komunikasi, Atribut Destinasi

The Use of Nanosilica for Improving of Concrete Compressive Strength and Durability
Abstrak

 

The development of construction materials technology, particularly concrete is growing

very rapidly in the presence of nanotechnology. One material that deserves the attention of researchersis nanosilica. Silica has been used on concrete, starting from silica sand as a filler to microsilica (silicafume) as a reactive pozzolan. Based on previous research, silica fume is proven effective to improvethe mechanical properties and durability of concrete. A novel nanotechnological process allowsproducing amorphous nanosilica with high reactivity from locally available silica sand. In this study alocally available nanosilica is used on mortar and concrete thereby limiting the use of commercialnanosilica materials from semiconductor industry waste. To obtain sustainable concrete, the mix isdesign to have high strength as well as low permeability using as much possible local sources. This study also make use of commercial, regular silica fume combined with the locally produced nanosilica. The results show that combined use of nanosilica with silica fume can increase the compressive strength and durability.

Keywords: Nanotechnology, Nanosilica, Compressive Strength , and durability

Development of Mix Proportion For High-Performance Concrete Using Locally Available Ingredients Based on Compressive Strength and Durability
Abstrak

 

The use of concrete materials to date, remain a key ingredient in such construction work onthe construction of building, bridges and infrastructure. One indicator is the increased production ofreadymix concrete which is nearly 16 billion tons in 2010. But the increased used of concrete,apparently bring the impact of environmental damage. This is due to the fact that production of rawmaterials contributes greatly to CO2in the air. One effort to reduce such impact is to use of highperformance concretes. Mix proportion of High Performance Concrete are strongly determined bythe quality and availablity of local materials. The implications of research result from other countriescan‘t be directly used. Therefore is need to the research on development of High Performance Concrete mix using locally available materials. In this research the mix proportions for f’c : 60 and 80 MPa are developed using local materials that are commonly used by readymix producers. The high Performance Concrete is developed based on compressive strength and durability. The result is expected to be applied to readymix industry particularly for construction use in Indonesia.

Keywords: High Performance Concrete, mix proportions, compressive strength , and durability

Material Development of Nano Silica Indonesia for Concrete Mix
Abstrak

 

Based on data from Indonesian Directorate General of Mineral and Coal Technology,

popular sources of silica sand in Indonesia can be found: Bangka Belitung, Pangkal Pinang,South Sumatra, Lampung, West Kalimantan, South Kalimantan, West Java, and East Java. Unfortunately, the use of silica sand in concrete mix is still limited as filler material. The challenge is then to explore the use of such silica sand, for instance in the form of nano silica. This research work explores silica sand from: Bangka Belitung, Pangkal Pinang, Lampung, West Java, East Java, West Kalimantan and South Kalimantan. The selected silica sand are then processed by the novel method developed by Indonesia Center for Ceramics using Polishing Liquid Milling Technology. The result is expected to contribute in the development of increased added value of locally available silica sand and to advancing application of nano silica for concrete.

Keywords: Nanotechnology, Nano silica, Characterization, Polishing Liquid Milling Technology
