Stainless Steel 316L is metal that can be used as a bone plate, but it has low biocompatibility. To achieve better biocompatibility with bone, Stainless Steel 316L can be coated with hydroxyapatite. Hydroxyapatite (HA) is the main inorganic phase of human bone with a composition around 65% of our bone. Dip coating techniques was used to applyhydroxyapatite into Stainless Steel 316L. Stainless Steel 316L with a size of 2x1x0,1 cm was dipped into a suspension containing HA, sago starch and water mixed with a rate of 250 rpm for 20 hours. Suspension were prepared with compositions 16 gram, 18 gram and 20 gram aquadest. And then coating HA were dried in oven at temperature 110 °C for 30 minutes.Coating HA were sintered at temperatures of 600°C, 700°C and 800 °C for 1 hour. SEM observation showed that the thickness of HA coating composition of 20 gram, 18 gram and16 gram increased in the range of 42 – 144 μm. Maximum shear strength obtained in this research was 11,78 MPa.Keywords : Coating, Dip Coating, Hydroxyapatite, Stainless Steel 316L

Bacgkround: Efforts in the eradication of mosquito breeding have been done, but have not shown maximum results due to lack of community participation caused by several factors, such as lack of knowledge, attitude and practice that are considered to play important role in reducing the incidence of vector-borne diseases transmitted by mosquitoes. This study aimed was to determine the relationship of knowledge, attitude and practice of cleaning services with the amount of mosquito larvae at water container around Bhayangkara Hospital Palembang. Populations in this study were 25 cleaning services in Bhayangkara Hospital Palembang. Methods: Samples in this study were all populations taken by using total sampling technique. Data included the number and types of water containers, the number and species of mosquito larvae found in the water containers, and data of knowledge, attitude and practice of cleaning services. The results were analysed using Kruskal-Wallis statistic test. Results: There were 75 water containers, 63 water containers were indoors, one of them contains larvae, and 12 water containers were outdoors, the type of two outdoors water containers that contained larvae were plastic buckets. Total larvae that found were 16 larvae of Aedes aegypti. Based on Kruskal-Wallis statistic test, there was no average difference between the number of mosquito larvae based on knowledge with p>alpha± (0.072>0.05), and there was an average difference between the number of mosquito larvae based on attitudewith p<alpha± (0.006>0.05) and practice with p<alpha± (0.019<0.05). Conclusion: There was a negative association between attitude and practice against the number of mosquito larvae, but not with knowledge.

Abstract Environmental education plays a strategic role in changing human perceptions and attitudes towards environmental problems in the long term. early environmental education is very important in building a generation that cares and is responsible for the environment. This service aims to increase environmental awareness in rural schools through a socialization program involving lecturers as resource persons. Through this service program we managed to show a significant increase in environmental knowledge and awareness among students after attending the socialization program. Students showed positive behavioral changes such as throwing garbage in its place and participating in environmental conservation activities for example greening, and working together to clean their school environment. Keywords: Environmental Awareness; Cleanliness; Waste; Rural Schools Abstrak Pendidikan lingkungan berperan strategis dalam mengubah persepsi dan sikap manusia terhadap masalah lingkungan dalam jangka panjang. pendidikan lingkungan sejak dini sangat penting dalam membangun generasi yang peduli dan bertanggung jawab terhadap lingkungan. Pengabdian ini bertujuan untuk meningkatkan kesadaran lingkungan di sekolah-sekolah pedesaan melalui program sosialisasi yang melibatkan dosen sebagai narasumber. Melalui program pengabdian ini kami berhasil menunjukkan adanya peningkatan signifikan dalam pengetahuan dan kesadaran lingkungan di kalangan siswa setelah mengikuti program sosialisasi. Siswa menunjukkan perubahan perilaku yang positif seperti membuang sampah pada tempatnya dan berpartisipasi dalam kegiatan pelestarian lingkungan contohnya melakukan penghijauan, dan melakukan kerja sama membersihkan lingkungan sekolahnya. Kata Kunci: Kesadaran Lingkungan; Kebersihan; Sampah; Sekolah Pedesaan
