    Sugar is a strategic commodity for Indonesia, such that the availibility and the price have been managed by the government. The national production of Indonesia sugar has not been enough to cover the consumption, such that the deficit must be imported. Indonesian sugar was produced by 61 factories, where 51 units are State-owned Company. Unfortunately, the quality of sugar produced by State – owned factory has been getting worse, such that some are not qualified to the Indonesian National Standards (SNI). One of the reasons is poor process technology adopted, which is mostly using sulfitation technology. The Government, therefore, encourages industry to migrate the process technology from sulfitationsystem to defecation remelt carbonatation (DRK) system. This study assesses the techno-economy feasibility of the migration. The results indicate that technology migration is technically feasible, but for the business, Government needs to give price incentive to the product. Furthermore, the study recommends that adoption of DRK technology should be prioritized to the factories with abundant stock of baggase

    The program of elimination of mosquito breeding places is still low since there is no public participation effort in vector control. Social capital is key factor for sustaining any health programs implemented. This study was aimed to analyze the effectiveness of social capital impact on participation and environmental based dengue prevention programs. Study design was cross sectional. Population study was community around Bantul district. Sample was collected as 600 house hold devide on two categories endemic and potential areas. Data was collected with interviews and observation. Data were analyzed with person corelation, confirmatory analyzed and path way analyzed. There were significantly relationships between social capital and family perseption, disease perception, individual perception, environment perception and larva density p < 0,05. Relationship between perception of counselling and family perception, dengue programs and family perception p < 0,05, and the strongest factor is environment participation (r=0.296). Based on the path analysis for potential areas, social capital was effectively for increased larvae free index through family perception. Theoretically, model for social capital is more efficient in increasing the number of free larvae index through community environment participation. In potential areas, social capital is concluded to be more effectively increase of larva index through participation of individuals. In endemic areas, that dengue programs increase larva index more effectively, compared with social capital does. Strengthening of social capital is important because it effectively the coverage of larva index through environment participation both areas

    Full text link
    Lobster air tawar menghadapi banyak hambatan dalam upaya peningkatan produksi lobster air tawar seperti tingkat pertumbuhan yang kurang optimal serta tingginya tingkat kematian pada fase pasca larva, salah satunya karena faktor salinitas. Domestikasi merupakan suatu cara pengadopsian hewan dalam suatu populasi yang hampir punah (terancam kelestariannya) dari kehidupan liar (habitat asli) ke dalam lingkungan budidaya.Hasil penelitian menunjukkan bahwa salinitas berpengaruh nyata (p<0,05) terhadap pola osmoregulasi, pertumbuhan, dan efisiensi pakan. Pola osmoregulasi lobster air tawar pada perlakuan S3 (14 ppt) mengalami pola osmoregulasi isosmotik, sedangkan S4 (21 ppt) mengalami pola osmoregulasi hiperosmotik. TKO terendah terdapat pada perlakuan S3 (14 ppt) sebesar 30,54±0,01 mOsml/l H20, sedangkan pada perlakuan S4 (21 ppt) memiliki TKO tertinggi yaitu sebesar 287,82±0,04 mOsml/l H20. Laju pertumbuhan mutlak terbaik pada perlakuan S3 (14 ppt) yaitu 3,51 gr dan efisiensi pakan pada perlakuan S3 (14 ppt) sebesar 20,04%
