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.

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.

Leprosy stills a public health problem in West Sulawesi which has a Case Detection Rate (CDR) around 43.69/100.000 population. Household contacts of leprosy are a high risk group to be infected, due to droplet infection mode of transmission of the disease. A nose swab examination and serological study was conducted to detect exposure of M. leprae of people who live in leprosy endemic area. Detection of M. leprae in the nasal cavity will represent the exposure rate from outside and the measurement of specific antibody is represented the result of exposure to the immune system. Two group of inhabitants (30 household contacts of leprosy and 30 nonhousehold contacts) were involved in the study. They live in Banggae district, a leprosy endemic area of Majene Regency, West Sulawesi. Sixty nose swab samples and sixty capillary blood samples from the same invidividuals of the two groups were collected and sent to Leprosy laboratory of the Institute of Tropical Disease, Airlangga University Surabaya. A Polymerase Chain Reaction (PCR) was performed to the nose swab samples for detection of M. leprae. The blood samples were examined serologically to measure the level of anti PGL-1 antibody. PCR examination of nose swab samples showed 1/30 positive result in the household contact group and also 1/30 positive result in non-household contact of leprosy (statistically no significant difference, p > 0.05). Serological study showed higher sero-positive result in the household contact group (15/30 or 50%) compared to non-household contact (11/30 or 36%), but statistical calculation revealed no significant difference between the two groups (p > 0.05) on sero-positive results of leprosy. It is concluded that household and non-household contact in leprosy have the same risk to be affected by the disease. The term of household and non-household contact need to be redefined. The possible role of exposure from the environment was also discussed, especially from non-human resource of M. leprae.

Drug resistance in leprosy is important for Leprosy Control Program, since the WHO-Multidrug regiment (MDT) has been used for global treatment of leprosy for more than two decades already. A Dapsone resistance case in a Multibacillary (MB) leprosy case is reported. The patient was diagnosed and treated in Tajuddin Chalid Hospital Makassar, South Sulawesi. Previously he was treated in a health center at South Sulawesi and was given a treatment for one year, before referred to the hospital. The leprosy skin lesions are still active with erythematous skin lesions and thickened ear lobe. Bacteriological examination was positive for Acid Fast Bacilli, the Bacterial Index was 3+ and the Morphological Index was 1%. The specimens of M.leprae isolation was sent to the Institute of Tropical Disease Surabaya for drug resistance study. Using the Lp1-2 and Lp3-4 nested primers, PCR test was positive for M.leprae.Sequencing result for folP gene showed a double mutation at codon 53 (ACC / Threonin ) which become (AGG / Arginine). Simultaneous mutation at two nucleotides at one codon has never been reported in Indonesia before and this phenomenon is important for leprosy control policy.

Background: The intensity of Mycobacterium leprae exposure to people who live in leprosy endemic area could be measured by serological study and detection of the bacilli in the nose cavity. Different geographical altitude might have some influences to this exposure since the bacilli prefer to live in warm areas. Aim: A combined serological and PCR study of leprosy was conducted in Selayar island, South Sulawesi to 80 school children (40 from low land and 40 from highland altitudes) in order to compare the exposure intensity between the two areas. Method: Anti PGL-1 IgM antibody (ELISA) and PCR study to detect M.leprae in the nasal cavity were performed simultaneously from each person. Result: Seropositive cases were found in 23/40 children from low land compared to 16/40 children from high land, but statistically no significant difference (p>0.05). PCR positive for M.leprae in the nasal cavity only found in 1/40 children, both in low and high altitude. Conclusion: It is concluded that although the existence of M.leprae in nasal cavity is minimal, the intensity of exposure to this bacilli still high as indicated by serological study.

Leprosy in twins is rarely reported. A 19 years-old male student, from Lamongan district, was diagnosed as Multibacillary (MB) leprosy in the Skin and STD Clinic of Dr. Soetomo General Hospital Surabaya. Multiple anesthetic skin lesions were found, but the bacteriologic examination was negative for Acid Fast Bacilli (AFB). Histopathology examination support the diagnosis of BL type of leprosy. His twin brother that has been lived together since born until present seems healthy without any complaints of skin lesions and have no signs of leprosy. When a serologic examination for leprosy was performed, a high anti PGL-1 antibody level was found in patient (IgM anti PGL-1 2937 and IgG anti PGL-1 3080 unit/ml) while his healthy twin brother showed only low level (IgM 745 and IgG 0 unit/ml). Interestingly when a PCR study was performed to detect M.leprae in the blood, both of them showed positive results. Using the TTC method, a genomic study of for M.leprae, it is revealed that both samples were identic ( 27x TTC repeats). According to patient's history, he had a traffic accident and got a wound in the knee seven years ago, while the skin lesions seems started from this area around three years ago before it spread to other parts of the body. The patient was treated with Multi-drug therapy (MDT) while his sibling got a prophylactic treatment for leprosy. After 6 months of treatment, the leprosy skin lesions were diminished and the serologic anti PGL 1 has been decreased. His healthy brother also showed a decrease in anti PGL 1 level and no skin signs of leprosy.

Leprosy still a health problem in Indonesia, where many leprosy pocket areas still persists, especially in the eastern part of the country. Although the program of WHO – Multidrug Therapy (MDT) regiment has been conducted elsewhere since 1980s, only the prevalence can be reduced but not the incidence of new leprosy cases. Theoretically after the source of leprosy (the infectious leprosy cases) has been treated, no more transmission of the disease and should be no more new leprosy cases will be found. To explain this phenomenon, the non-human resource of M.leprae became a new topic of debates, especially the existence of bacteria in the environment. A field study of the existence of M.leprae in the environment of leprosy endemic area had been conducted in a leprosy endemic area of the northern part of East Java. The aim of the study is to find any correlation of the existence of these bacteria in the environment with the presence of leprosy patients who live in that area, in order to study its role in the transmission of the disease. Ninety water samples from wells in the house of inhabitants who live in one endemic sub district were collected. The owner of the well was interviewed whether any leprosy patients who routinely use the water for their daily life activities. Water samples were examined by Polymerase Chain Reaction (PCR) method to detect M.leprae DNA, using the LpF-LpR and Lp3-Lp4 nested primers (99bp). The PCR results showed positive band for M.leprae in 22 out of 90 (24%) water samples. Water samples from wells that used by leprosy patients showed positive PCR in 11/48 (23%), while 11 out of 42 (26%) water samples from wells that never been used by leprosy cases showed positive result. Statistically there was no difference (p>0.05) in the positivity of M.leprae between the two groups. It was concluded that the existence of M.leprae in the daily water resource was not correlated with the present of leprosy cases in the area. Possible symbiosis between protozoan and mycobacterium in the environment were discussed.

The "Iceberg phenomene” has been used to explain this situation which indicate that these new leprosy cases is originated from Subclinical Leprosy. Fifty eight healthy school children who live in Jeneponto Regency, a leprosy endemic area in South Sulawesi were recruited. The first examination was performed in 2007 and sera samples were kept in deep freeze refrigerator. In 2010 these children were re-examined for clinical leprosy and sera were collected again. ELISA study was performed simultaneously to these 58 pairs of sera (2007 & 2010) for measuring the titer of IgM anti PGL-1 antibody (ELISA) and the level 605u/ml was regarded as cut off value. After three years evaluation, none of these children showed any clinical signs of leprosy, but 20 of 22 ( 90.9%) children were remained sero-positive and only 2 (9.1%) became sero-negatives. In other sites, 5 children that previously sero-negatives became sero-positives after 3 years. Eight of 10 (80%) children who showed sero (+) with high titer (>1.000u/ml) in 2007, were also remained in high titer. The mean titer of 2007 was 627.8 u/ml, and after3 years became 723.9 u/ml (p<0.05). Although there is no progression from Subclinical to Manifest Leprosy cases among these children, the number of sero (+) cases were increased and the mean titer of IgM anti PGL-1 antibody was significantly increased.. The majority who previously showed high anti PGL-1 antibody titer, remained in high level. This study support the "iceberg phenomene” theory in Leprosy.

East Java province still has some pocket of leprosy endemic areas. In order to solve the problem, molecular typing will make it feasible to study the transmission pattern of Mycobacterium leprae in leprosy endemic area. The present study is to analyze the presence of M.leprae DNA in the environment and to study variation number of TTC repeats and their distribution. Poteran Island is located in Madura, East Java and was chosen because this island has a high prevalence of leprosy and remains stable for the last five years. All samples were analyzed by PCR and the numbers of TTC repeats were confirmed by direct sequencing. Of all collected samples, 26.4% isolates of water resources (24); 61.9% nasal swabs (26); and 35.3% skin tissues (24) are positives. No statistically difference in the pattern distribution of TTC repeats between skin tissues of patients and nasal swab of households contact (p=0.594); also distribution of TTC repeats between skin tissues of leprosy patients and those of water resources (p=0.441); and distribution of TTC repeats between nasal swab of households contact with water resources (p=0.906). It means that the transmission of M.leprae in leprosy endemic area has closely related in 3 aspects: agent, host & environment.
