The birth of a healthy baby is generally around 38-42 weeks of pregnancy. However, there are many babies born at an inadequate age of birth and the age of birth that is past its time. This study aims to predict the age of the birth of a patient. The method used is a classification with the Naïve Bayes algorithm with input variable (X), the factors experienced by pregnant women in the form of 8 variables X and Y variable in the form of Birth Age. Problems that arise are too many attributes that affect the results of accuracy. To overcome this, preprocessing is used with the Correlation Based Features Selection (CBFS) method. CBFS chose the X variables which had the highest correlation with the Y variable (Birth Age) but had the least correlation between the X variables. From the CBFS that had been done, produced 4 X variables, namely: blood pressure, number of babies, congenital diseases before pregnancy, and problems during pregnancy. The results of the test showed an increase in Precision, recall, and accuracy in the Naïve Bayes classification when implemented CBFS. The highest value of accuracy after preprocessing is 67% with an increase of 2 percent compared to before preprocessing.
University library accreditation aims to improve library quality. In order to get formal recognition from the state, university libraries apply for accreditation to the National Library to assess whether they have met national standards. This study aimed to determine implementation the management of university library accreditation with national standards at the University of Malang (UM). The research method used the descriptive qualitative method, which described management functions performed by UM library in the university library accreditation. The results research showed that library accreditation management carries out planning, organizing, implementing, and monitoring processes. Management functions are described in accreditation ranging from planning to supervisory functions. The planning process is to design accreditation activities structurally and organizationally to achieve the expected conditions through team planning, physical evidence, and accreditation performance. Organizing processes are forming an organizational structure and detailing the duties of accreditation team members to play an effective role by classifying accreditation instruments, organizing teamwork, and accreditation documents. General and technical guidelines for university library accreditation guide the implementation process to obtain optimal performance from the accreditation team through completing documents, preparing for visitations, correcting forms, and conducting self-assessments. The monitoring process avoids deviations by evaluating the administration, budget, forms, performance, and physical evidence of accreditation. The study concludes that the implementation of accreditation management through planning, organizing, implementing, and monitoring aims that the UM library can achieve accreditation objectives, namely obtaining satisfactory results as well as the legitimacy, reputation, and legality of the library.
The purpose of this study was to determine the structure and condition of seagrass communities in the waters of hadirin Beach and Batu lawang karimunjawa. national park. This exploratory research used descriptive qualitative methods, each study location is divided into two transects. Data identified at SPTN Office 1 Kemujan Karimunjawa National Park. The results of the study were six species of seagrass, namely: Holodule uninervise, Thalassodendron ciliatum, Halophila minor, Syringodium isoetifolium, Thalassia hemprichii and Cymodocea serrulata. The percentage of seagrass cover namely Holodule uninervise is 38.04 %. Thalassodendron ciliatum of 6.25%, Halophila minor of 29.56%, Syringodium isoetifolium of 31.25%, Thalassia hemprichii at 14.21% and Cymodocea serrulata to 16.9%. The highest density of seagrass species in Hadirin Beach is from the Uninervise holodule species 72.30%, with 858 stands on the first transect and 54.66% on the second transect with 253 stands. Whereas for the highest Batu Lawang Beach is the species of Thalassia hemprichii 51.1% with 162 stands, on the first transect and 44.9% with 114 stands. The substrate has the type of sandy clay and coral fragments. Holodule uninervise is the most dominant species found on the beach of Hadirin meanwhile Thalassia hemprichi is the most dominant species in Batu Lawang.
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.
