This research aims to produce and characterize the macro nutrient value in compost from Mamasa coffee waste using the microorganism bioactivator EM 4. This research was carried out by mixing coffee waste with EM-4, water and sugar in certain proportions. The composting process lasts for four weeks, with observations every week to trigger physical and chemical changes in the compost produced. The research results showed that the compost produced had good physical characteristics, namely black in color, not lumpy and odorless. Determination of macro nutrient levels in the organic material of Mamasa coffee waste before and after fermentation into compost showed a significant increase in the macro nutrients it contains, namely total organic C 25.59%; organic matter was 43.91%, Nitrogen was 2.53%, P2O5 was 1.95%, K2O was 1.68%, C/N ratio was 9.48 and water content was 24.34%. Thus, Mamasa coffee waste can be processed into high quality compost using EM-4, thereby providing a sustainable solution for managing organic waste and increasing soil fertility.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"31 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141382835","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}

Stroke is the second highest cause of death worldwide. The total prevalence of stroke continues to increase in the world and in Indonesia. However, stroke treatment is still less effective, so adjuvant therapy needs to be developed; one of them is MLC901. However, this therapy still needs to be studied further regarding its effect on acute ischemic stroke and the biomarkers used as the prognostic factors, such as red cell distribution width (RDW). This paper aims to determine the effect of MLC901 therapy on RDW values in acute ischemic stroke by analyzing various previous studies from different databases as a reference. Increased RDW values are associated with poor outcomes of acute ischemic stroke. MLC901 was shown to have neuroprotective and neurorestorative abilities in neurons that are under stress due to ischemia. MLC901 also can reduce inflammatory responses, reduce oxidative stress, and increase erythropoietin (EPO) production. So, administration of adjuvant MLC901 therapy can reduce RDW values and improve neurological outcomes in acute ischemic stroke.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"5 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141383831","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}

The research method involved analyzing six seaweed samples using atomic absorption spectrophotometry (AAS) to measure Pb content and calculate the dry matter yield. The results showed that the SB samples (SB1, SB2, SB3) did not contain detectable levels of Pb, indicating that their growing environment was relatively free from heavy metal contamination. In contrast, the SS samples (SS1, SS2, SS3) showed detectable levels of Pb, with the highest concentration in SS2 (2.65 mg/kg). The dry matter yield in the SB samples averaged around 20%, while the SS samples had a slightly higher average yield of around 21.5%. These results indicate that the SS samples had a higher dry matter content compared to the SB samples. Based on these findings, it is concluded that the SB samples are safer for industrial use due to the absence of Pb contamination, whereas the SS samples require further treatment to reduce the risk of Pb contamination. This study emphasizes the importance of regular monitoring and testing for heavy metal content in seaweed to ensure product quality and safety, as well as effective environmental management of coastal waters to prevent heavy metal contamination of vital natural resources.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"33 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141382294","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}

One aspect of animal evolutionary development is learning behavior. Learning behavior in animals, especially those related to intelligence, is correlated with the relative size of the animal's brain. This research has examined the comparison of intelligence levels and relative brain size between animals, especially four species of animals from the Order Rodentia, namely mice (Mus musculus), mice (Rattus assimilis), hamsters (Mesocricetus auratus) and guinea pigs (Cavia porcellus). The learning ability of test animals was measured using the T-Maze procedure according to a complete group randomized experimental design. Data on the learning ability of the test animals were processed using ANOVA Model I and continued with the Orthogonal Contrast Test. The results of the research show that the average learning ability from highest to lowest is possessed by mice, hamsters, guinea pigs and mice. This learning ability data is in sync with data on relative brain size, namely the relative size of the largest brain in mice and the relative size of the smallest brain in mice. The learning ability of mice and rats, which both come from the same family, namely Disciples, is not significantly different from that of hamsters from another family, namely Cricetidae. Rats, mice and hamsters, which all come from the same suborder, namely Myomorpha, have much higher learning abilities compared to guinea pigs which come from another suborder, namely Hystricomorpha.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"40 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141385751","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}

Bacteria were isolated from the rhizosphere of peanut plants, while pathogenic fungi were isolated from large chili fruit infected with anthracnose disease taken from Jelantik Village, Central Lombok Regency. Characterization of isolates for siderophore production used the Arnow method, while the protease enzyme production test used SKIM Milk Agar media. Next, the inhibition test of bacterial isolates against pathogenic fungi was carried out using the dual culture method. Characterization of potential isolates was carried out by observing bacterial colony morphology, gram staining and biochemical tests. The results of the siderophore production test showed that there was one isolate capable of producing siderophores with the isolate code RKT2.
