The presence of chlorophyll-a is an indicator of water fertility, where the high chlorophyll-a content will be followed by the presence of zooplankton which will then affect other aquatic organisms that form the food chain. The interaction of chlorophyll-a concentration on the presence of mackerel in West Halmahera waters is unknown, so this study was carried out with the aim of examining the relationship between chlorophyll-a concentration in West Halmahera waters and mackerel catch. The use of experimental fishing methods from May to July 2020 and non-linear regression analysis and Generalized Additive Model (GAM) are expected to provide an overview of the relationship between the two research variables. The results showed that the distribution of Indian Mackerel was more in coastal areas with a chlorophyll-a concentration distribution of 0.18 - 0.39 mg/m3 which played a major role in determining the variability of the quantitative distribution of mackerel (α < 0.05) and positively correlated with a value of r = 0.819 and these results supported by predictions using GAM, where the potential fishing area for mackerel in West Halmahera waters is at a chlorophyll-a concentration value of aboutb 0.2 - 0.4 mg/m3.
Fish population dynamics are determined by the balance between population increase resulted from growth and addition of new individuals (recruitment), and population decrease due to fishing mortality and natural mortality. It is important to understand fish resources condition, including their change pattern caused by pressures on coral reef fisheries resource in coastal area of Ternate Island. This research aimed to analyze mortality and exploitation rate of several reef fishes that caught at coastal area of Ternate Island. Stock assessment method was used to determine the mortality and exploitation rate of some reef fishes. Study results showed that the fishing mortality of the sample species was lower than their natural mortality, while the exploitation rate results also showed the same condition those found in mortality rate, where the fish with high growth coefficient tended to have high mortality rates.
the prevalence of malaria disease is still high in Indonesia. It requires to be diagnosed and handled quickly to decrease themorbidity and the mortality. the purpose of this study was to evaluate the results liver and kidney function tests of malaria patients forcomplications and to know the etiology. A cross sectional method was used for this study by using medical record of malaria patientsthat at Wahidin Sudirohusodo hospital in Makassar during January to December 2006. Malaria was diagnosed based on pheripheralblood while the examination of Sgot, SgPt (DgKC method), ureum (Barthelots method) and creatinine (Jaffe's method) were doneby chemistry autoanalizer. the increasing concentration of Sgot was found on 14 patients (42.4%) which was consisted of high at 12patients, SgPt on 13 patients (39.4%), ureum on 2 patients (6.1%) and creatinine on 11 patients (33.3%). Plasmodium falciparum wasfound on 18 patients (54.5%) and Plasmodium vivax on 15 patients (45.5%). the Sgot, SgPt, ureum, and creatinine concentrationsmostly exist in normal range, this indicated that liver and kidney damage was still mild. the etiology of malaria disease was Plasmodiumfalciparum and Plasmodium vivax, it was found from examination of pheripheral blood. there was no significant different in this studyfor the increasing of Sgot, SgPt, ureum and creatinine concentrations based on plasmodium etiology.
This study aims to analyze the effect of good governance on the quality of financial reports. This research was carried out in the vertical agency of the Ministry of Agriculture in the South Sulawesi Region using the survey method. The instrument in this study was in the form of a questionnaire. In this study, the sample used is 74 which is a saturated sample from the finance department, commitment making officials, procurement officials and goods managers in each work unit. The method used in this study is quantitative using a simple linear regression analysis tool. In conducting simple linear regression testing, this study uses the help of the SPSS (Statistical Package for the Social Sciences) application version 21. The results of this study indicate that good governance has an effect on the quality of financial reports.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
