Abstract

Population data needs are absolute things that must be met by BPS, but the most complete source of population data comes from population census results. Meanwhile, the implementation of the population census is only once every 10 years because it requires cost, time, and energy. Population prediction in the following year in each census period needs to be done to determine the difference in population growth in that year. Therefore, researchers are interested in studying the "Application of the Advanced Newton Gregory Polynomic Method and the Newton Gregory Backward Polynomic with the Hamilto-Perry Method in Predicting the Population of North Sumatra." this case the researcher will analyze between the three census periods. The purpose of this study is to obtain effective results from the three methods so that it can be used as an alternative application for the Central Statistics Agency (BPS) of North Sumatra province to predict the population in the year between the census. For Hamilton-perry, the application of the method is easy to do because the calculation process is uncomplicated and the data used as prediction material is very minimal, but the predicted value produces a non-rounded value so it needs to be rounded but when the value has been rounded there is a difference between the value not rounded to the rounded value aggressively. Therefore we need an adjustment to the value of rounding results based on the value not rounded. Then based on an aggregate trial of population prediction using the Hamilton-Perry method it produces a value that is higher than the actual value. For the advanced newton gregory polynomic method and the backward newton gregory polynomic each obtained total relative error isΣ????????=0,31412327 and Σ????????=0,3522818. From the two relative errors it is known that the total error for the advanced Newtonton polynomial method is smaller than the total error for the backward Newtonian polynomial method. Thus the Newton Newton method of advanced polynomial has better accuracy

Abstract

Along with the increase in the number of human population and economic conditions that are increasingly advanced, the public awareness of health is increasing. In addition, currently access to services for the Social Security Administering Agency (BPJS) is getting wider, the hospital must be able to add capacity to existing facilities and improve the quality of services. This study aims to implement the Fuzzy Servqual method and Quality Function Deployment on the quality of BPJS Health services in H. Adam Malik Hospital and determine which attributes are priority improvements. Data processing based on the criteria of the Fuzzy-Servqual method by determining fuzzy sets, fuzzyfication and defuzzyfication. determine the Gap and determine the priority of improvement using the Quality Function Deployment method. The results of this study indicate that all 19 BPJS service attributes provided by applying the Fuzzy Servqual method still do not meet patient expectations, because the value of patient satisfaction with services is still lower than the expectation value. Attributes that must be prioritized to improve their quality, namely: Revelation Attribute of Q2 with a gap value -3.68, Revelation Attribute of Q7 with a gap value of -1.58., Revelation Attribute of Q12 with a gap value of -1.58. The technical response that became the main target was the Procurement of Excellent Training Services, the addition of AC Fan in the inpatient room, making improvements to the facilities and infrastructure.

Abstract

The existence of leprosy or kusta or Morbus Hansen or Hansens disease has been known for years, including in Indonesia. Starting from the discovery of Mycobacterium leprae isolates from ancient bone (about 1.000 years B.C), the archaeological excavations results in East Nusa Tenggara, interesting questions arise about how the development of leprosy in eastern Indonesia is. Biology molecular study would become a powerful tool to investigate the presence of leprosy bacillary whether there are similarities between the genomes of M. leprae isolates in the primeval and the present. PCR examinations were performed on mandibular bone fragments from ancient human who lived 1000 years B.C. discovered in archaeological surveys on the island of Lembata and three leprosy patients from East Nusa Tenggara. The DNA extraction was performed using a kit from Qiagen products and its TTC repeating pattern was seen with the method of direct sequencing. It turned out that the TTC profile obtained from samples of archaeological was as many as 13 copies, while the repetition of TTC in three samples of leprosy patients were 15, 17 and 26 copies. The different number of TTC repetition shows the different isolates of M. leprae between in the ancient times and the present. Further studies are needed to verify the differences in the genome that occur, for example from the study of SNPs (single nucleotide polymorphisms).

Abstract. The purpose of this study was to determine the level of understanding of Elementary School Teacher Education Students as prospective teachers regarding the use of Dakota visual aids in learning mathematics. This research was conducted in the Elementary School Teacher Education Study Program, University of Quality, Berastagi, with a population and sample of 28 students in Semester 1 of the 2022/2023 Academic Year. The type of research used is classroom action research. Based on the research conducted, PGSD students have various levels of understanding about the use of the Dakota visual aid in teaching the smallest common multiple and the largest common factor. The difference in the level of understanding is caused by differences in students' cognitive abilities. The evaluation results show that the percentage of students' understanding of the five material components assessed is as follows: regarding the teaching of multiples material, 53.57% of students have an understanding in the high category and 46.43% in the medium category. For teaching factors there are 50% of students with understanding in the high category and the other 50% are in the medium category. For fellowship teaching there are 57.14% of students with understanding in the high category. 28.57% of students are in the medium category and 14.29% of students with low understanding. For KPK teaching, there were 89.29% of students with an understanding in the high category and another 10.71% in the medium category. For FPB teaching, there are 71.43% of students with an understanding in the high category, 17.86% of students with moderate understanding, and another 10.71% with a low category.

Abstract

Penjaringan Sari Flats is a solution implemented by the Surabaya City Government to overcome the limited housing in Surabaya. Due to the high number of residents , Penjaringan Sari Flats have a rapid and spread infectious rate. One of the impacts of infectious diseases that may be experienced by pregnant women and also children under five aged is low birth weight (LBW) babies and stunting. One solution to reduce the number of stunting and LBW that can be done is screening at early conditions of infection in pregnant women and toddler using the urine examination method (urinalysis). In examining a urine sample which is examined using the dipstick method (urinalysis using strips), 11 parameters can be read. Three of the eleven dipstick parameters (nitrite, leukocytes, and protein) were stated to be sufficient to screen a patient's initial infection profile. Participants in this community service activity are residents of Penjaringan Sari flats who are female, pregnant, and/or small children aged up to 5 years. The first stage carried out was the introduction of this program and activity plan to the Head of Penjaringan Sari Subdistrict. Data collection on the number of pregnant women and toddlers in Penjaringan Sari Village using observational methods. Data collection was carried out personally by the Head of Community Service accompanied by local women community. The number of pregnant women is 40 and toddlers are 60 as of August 2023. The results of urine sample examinations from 74 patients from residents of Penjaringan Sari Subdistrict are divided into two different categories: pregnant women and toddlers. In the category of pregnant women, around 90% of patients had positive leukocyte results, 60% had proteinuria, and 10% showed positive urine nitrite. In the second group, namely toddlers, the results showed that around 58.13% showed positive leukocytes, around 16.27% experienced proteinuria, and 4.65% of toddler patients had positive nitrite values.

Abstract

Indonesia was the third most recent case of leprosy globally in 2020 with 11,173 people, after India and Brazil. Most of the leprosy manifestations are asymptomatic. This is possibly as subclinical leprosy which individuals without leprosy symptoms but have leprosy specific antibodies high levels, so it has the potential to become a transmission and disability. Therefore, an ELISA test need for early detection in preventing leprosy transmission. This study aims to measure IgM and IgG antibody levels in leprosy patients and assess the accuracy of the measurement results. This research is a cross-sectional study. Five patients' blood samples have analyzed for IgM and IgG anti-PGL-1 antibody levels by ELISA. Accuracy interpretation of this measurement based on the %CV. Antibody levels were classified based on the cut-off <605 u/ml as IgM seronegative or <630 u/ml as IgG seronegative, 605–1000 u/ml as low seropositive IgM or 630-1000 u/ml as low seropositive IgG, and >1000 u/ml as high seropositive IgM and IgG. Among five patients examined, 40% had high seropositive leprosy with anti-PGL-1 IgM and IgG antibody titers>1000 u/ml, and 60% of patients had seronegative leprosy. Accuracy in this ELISA test shows high accuracy with %CV <10% in the conversion of OD to antibody titer levels.  IgM and IgG Anti PGL-1 antibody titers by ELISA as one of the parameters in identifying patients at higher risk of leprosy. A significant portion of patients with high seropositive leprosy with high accuracy.
