Abstract

North Halmahera Regency is one of the mangrove spots of the Xylocarpus sp species with a fairly abundant amount. This study aims to determine the distribution map of Xylocarpus sp species and population character of Xylocarpus sp in North Halmahera Regency. This research was conducted from April to June 2021. The method used included a mapping survey of Xylocarpus sp by recording the coordinates from GPS for each Xylocarpus sp found. Determination of population character of Xylocarpus sp was done by observing plant morphology related to vitality and periodicity. Data analysis was carried out by processing coordinate data and observational data on the character of the population of Xylocarpus sp into a base map through a GIS application. The results showed that the species Xylocarpus sp. found in North Halmahera district was Xylocarpus granatum. The distribution pattern of Xylocarpus granatum in North Halmaera is spread in groups. Population characteristics show Xylocarpus granatum in very low sociality conditions, vitality in a well-growing state, periodicity in flowering and fruiting conditions.

Abstract

Early identification is needed to predict the condition of patients who are at risk of worsening symptoms to become more severe. Simple laboratory tests such as measurement of the neutrophil-lymphocyte ratio are known to be used as factors to determine the patient's prognosis in various clinical situations. The purpose of this study was to analyze the value of the neutrophil-lymphocyte ratio as a predictor factor for COVID-19. This study is retrospective, using medical record data of 327 Covid-19 patients at the Dr Chasan Boesoirie Hospital Ternate from April to September 2021. Subjects were classified as not severe and severe COVID-19. The value of the neutrophil-lymphocyte ratio was determined based on the results of a routine blood test (sysmex XN-1000B3 BF). Data were analyzed using SPSS version 16, Pearson's test to determine the relationship between NLR and severity and using the ROC (Receiver Operating Characteristic) curve to determine the strength of the relationship with the Cut-off value, p < 0.05 and AUC to determine the sensitivity and specificity of NLR to COVID-19 severity. Results: From 327 subjects consisting of 229 non-severe and 98 severe, the neutrophil-lymphocyte ratio (NLR) in the non-severe (3.45±2.02) was significantly different from the severe (9.73±5.64) (p < 0.00). The ROC (Receiver operating Characteristic) curve shows that the NLR has a sensitivity of 83%, specificity of 82% with a cut-off of 3.5 with a positive predictive value (PPV) of 88.2% and a negative predictive value (NPV) of 83.6%. The results of this study can be used as a reference for determining clinical prognosis using neutrophil ratio data.

Abstract

Ternate is one of the spots in the Walacea expedition. Ternate Island has unique characteristics in the diversity of flora and fauna. So far, information on local butterfly diversity has not been reported. The purpose of this study is to update the latest information on the diversity and distribution pattern of local butterfly species on the island of Ternate for conservation efforts. An exploratory descriptive research using survey method has been conducted at the research location on the island of Central Ternate. The results of the study found 88 individuals consisting of 15 types of local butterflies from 5 families, namely; 1) family Papilionidae as many as 2 species including Pachliopta polyphontes, Papilio sataspes; 2) the Nymphalidae family as many as 9 species including Euploea tulliolus, Danaus genutia, Mycalesis perseus caesonia, Paratica Aspasia-aspasia, Limenitis helena, Yoma sabina, Vindula dejone dorokusana, Ideopsis similis, Cyrestis acilia latifascia; 3) family Pieridae as many as 2 types Pieris brassicae, Eurema sari sodalis); 4) 1 species of Lycaenidae family (Arhopala major) and 5) 1 species of Callidulidae family (Callidula evander). The local butterfly diversity index value on the island of Central Ternate is H'= 2.33 categorized as low diversity. Furthermore, the analysis of the distribution pattern is 17.6 or S2 > x̄, categorized as group distribution.
