As a result of the ban, many farmers or animal feed producer seek solutions in various ways such as the addition of herbs, probiotics, and a combination of both, but there are still few reports on the role of herbs, probiotics and a combination of both for alternative substitutes for AGP. This study aims to determine the role of herbs in the growth of probiotics. Herbs used ginger, turmeric, galingale, wild ginger, and temuireng, while the probiotics used are Bifidobacterium longum, B. bifidum, Bacillus sp., and Saccharomyces cereviciae. The benefits of herbs in supporting probiotics were tested using the disc diffusion method. Chloramphenicol disc ware used as control positive. Observation and measurement of the growth zone of probiotics were carried out after incubation. The results of this study prove that herbs do not inhibit the growth of probiotics. Herbal content can be a prebiotic candidate that can support the growth of probiotics. The combination of herbal-probiotics can potentially be an AGP substitute in animal feed.","PeriodicalId":338791,"journal":{"name":"JURNAL BIOLOGI PAPUA","volume":"294 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115352488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DHF disease control has been applied so far, one of which is the use of larvacide temephos (abate). However larvacide is a chemical insecticide that has a negative impact on human health and causes resistance. Therefore in this research, biological control is carried out by utilizing entomopathogenic fungi as a larvacide. The purpose of this study was to determine the effectiveness of entomopathogenic fungi isolated from Ae aegypti larvae. Against the death of Ae. Aegypti mosquito larvae with the moist chamber method. This study used a completely randomized design (CRD) with a factorial pattern and performed two repetitions. Factor A is a type of fungi with 3 levels, namely A1: Aspergillus sp1, A2: Aspergillus sp2, and A3: Syncephalastrum sp. Factor B is a dilution with 7 levels, namely B0: Control, B1: 100 (without dilution), B2: 10-1, B3: 10-2, B4: 10-3, B5: 10-4, B6: 10-5 with every treatment was applied in 2 repetitions. Observations were made 24 hours after treatment for 3 days. Data were analyzed using analysis of variances (anova) and continued with the Least Significant Difference Test (LSD) at 5%.

Zinc is one of essential heavy metals for organisms but be dangerous for human if comsumed in high concentration. So, it is important to to solve the problem to reduce the concentration of zinc in east coast of Surabaya through bioremediation using microorganism. Zinc resistant microorganism could be isolated from zinc contaminated region and be used for bioremediation agent because some microorganism developed resistance mechanism to zinc by bioaccumulation or biosorption. The aims of this study are to isolate and characterize zinc resistant microorganism from east coast of Surabaya. The most resistant microorganism will be observed for the growth in medium supplemented with zinc and without zinc. The potency of the chosen isolate to biosorb of zinc was also analyzed. Water sample from east coast of Surabaya was serries dilluted and innoculated on Luria Bertani Agar medium using spread plated method. Microbial resistance to zinc was analyzed by grown the cell on medium containing various concentration of zinc to determine Minimum Inhibitory Concentration (MIC) value of each microbial isolate. Cell turbidity will be observed in the chosen isolate using spectrophotometer in wave length of 600 nm to get the growth curve. The potency of the chosen isolate to biosorb of zinc was analyzed using atomic absorption spectrophotometer. From this study, six bacteria and three yeast have been isolated from east coast of Surabaya, designated as PmbZn1, PmbZn2, PmbZn3, PmbZn4, PmbZn5, PmbZn6, PmbZn7, PmbZn8, dan PmbZn9. All isolates could grow on medium containing 8 mM ZnSO4. The most resistant bacterial was isolate PmbZn5 with the MIC of 9 mM ZnSO4.
