Encouraging Knowledge Sharing Behavior to Boost the Business Performance of Creative Industry (Study in Indonesia SMES’s Context)

SMEs creative sector has an important and strategic role in national economic development. MSMEs for the Indonesian economy are able to absorb labor about 97% and contribute to gross domestic product (GDP) about 57%. In fact, owners of creative SMEs in the city of Semarang not yet have an awareness of the importance of innovation and creativity development [16]. One of the biggest obstacles is that they do not have a structured program to explore the attractiveness and uniqueness of its products, consequently its products cannot compete competitively with foreign products that increase in the domestic market. The purpose of this study is to examine the factors that can explain the strategy to boost the performance of creative SMEs business through a habit of cultivating the behavior of knowledge sharing between owners, employees, consumers, competitors, government or other stakeholders. The higher the desire to share knowledge then potentially will increasingly bring up innovative ideas that can encourage business performance. The sample consisted of 185 owners of creative SMEs in Semarang City who answered the structured questionnaire. The data is processed by Wrap PLS version 6.

Perawatan Ulang Saluran Akar Insisivus Lateralis Kiri Maksila Dengan Medikamen Kalsium Hidroksida-Chlorhexidine

Banyak faktor yang menyebabkan kegagalan terapi endodontik antara lain pembersihan dan membentuk saluran akar yang tidak sempurna dan obturasi tidak hermetis sehingga menyebabkan kurangnya kemampuan untuk menghilangkan mikroorganisme yang ada. Saluran akar yang terinfeksi membutuhkan suatu medikamen untuk menunjang keberhasilan dalam perawatan saluran akar.Kalsium hidroksida merupakan salah satu bahan medikamen yang efektif karena memiliki sifat antibakteri dengan spektrum luas, pH tinggi, biokompatibilitas baik, mampu menetralkan endotoksin bakteri, memiliki sifat toksik yang paling rendah, serta menstimulasi pembentukan jaringan keras. Tujuan laporan kasus untuk menunjukan keberhasilan perawatan ulang saluran akar gigi insisivus lateralis kiri maksila dengan lesi periapikal menggunakan medikamen kalsium hidroksida- chlorhexidine. Pasien wanita umur 53 tahun, gigi insisivus lateralis kiri maksila dengan lesi periapikal.Radiografi tampak obturasi kurang hermetis dan radiolusen daerah periapikal. Perawatan ulang saluran akar,diikuti pemasangan pasak fiber frefabricated dan restorasi porselin fuse metal.Keseimpulan setelah evaluasi setelah enam bulan pasca perawatan ulang saluran akar, radiografi menunjukan radiolusen mengecil dan gigi dapat berfungsi dengan normal.Re-Treatment of Root Canal of Maxillary Left Lateral Incisor with Calcium Hydroxide-Chlorhexidine Medicament. There are many factors that cause failure of endodontic therapy. For instances, incomplete cleaning and shaping of root canal and inadequate obturation that results in difficulty to remove the microorganisms. Infected root canal requires a medicament for the success of the root canal treatment. Calcium hydroxide is one of the effective ingredients as medicament because it has broad spectrum antibacterial properties, high pH, good biocompatibility, and it is able to neutralize bacterial endotoxins, decrease tissue toxicity, and stimulate the formation of hard tissue. The purpose of this case report is to show the success of root canal treatment of the left maxillary lateral incisor with periapical lesions using calcium hydroxide-chlorhexidine medicaments. The patient was a woman aged 53, complaining about her left maxillary lateral incisor with periapical lesion. Based on the radiographic evaluation, there was less hermetic obturation and a radiolucent in the periapical. Root canal re-treatment was continued with fiber prefabricated post and porcelain fused to metal crown. After six months of evaluation and endodontic retreatment, it is found that there is a decrease of radiolucency periapical lesion, and her teeth are able to function normally
