Analysis of PAX9 and MSX1 Gene Mutations in Nonsyndromic Tooth Agenesis
No full textBackground: Tooth agenesis is the congenital absence of tooth buds.
Nonsyndromic tooth agenesis is the most commonly encountered form. This
abnormal condition can affect tooth development and aesthetic function. The cause
of agenesis is suspected to be influenced by genetic and environmental factors, with
genetics being the primary cause. PAX9 and MSX1 genes are the most frequently
discussed and identified in subjects with nonsyndromic tooth agenesis. Based on
previous research, mutations in PAX9 and MSX1 genes can lead to nonsyndromic
tooth agenesis. Aim: This study aims to analyze mutations in PAX9 and MSX1
genes and their implications on nonsyndromic tooth agenesis. Methods: This study
uses 26 blood samples from nonsyndromic tooth agenesis subjects. The blood
samples were extracted to isolate the DNA which were subsequently sent to the
Faculty of Dentistry, Chulalongkorn University, for sequencing. Demographic data
analysis was performed using SPSS software. Frequency and percentage were
calculated for categorical data, while mean, median, and mode were used for
numerical data. Results: Blood collection was performed on only 13 subjects with
tooth agenesis, and sequencing was conducted on only 4 subjects due to the limited
number of dental agenesis patients and time constraints. The results showed that
only the third sample had a mutation variant in the PAX9 gene with a significant
amino acid change. The other three samples showed the presence of mutation
variants in the PAX9 and MSX1 genes, with a less significant impact on gene
function. Conclusion: There are variant of uncertain significance (VUS) in the
PAX9 gene, and various impact variants found in the MSX1 gene.98 PagesTesis Magiste

Gangguan pendengaran dapat memperburuk hambatan tersebut. Penilaian pendengaran dini dan akurat pada anak dengan CP sangat penting, namun sering kali sulit dilakukan karena keterbatasan kerja sama dalam pemeriksaan perilaku. Penelitian ini bertujuan untuk menentukan prevalensi dan pola gangguan pendengaran pada anak dengan CP serta mengevaluasi hubungannya dengan faktor risiko dan subtipe CP. Bahan dan Metode: Penelitian potong lintang ini melibatkan 31 anak dengan diagnosis CP di Medan. Kriteria inklusi mencakup anak berusia di bawah 17 tahun dengan persetujuan orang tua. Data yang dikumpulkan meliputi karakteristik demografis, riwayat perinatal, serta subtipe CP berdasarkan klasifikasi klinis dan topografis. Pemeriksaan pendengaran dilakukan menggunakan timpanometri, otoacoustic emissions (OAE), dan Brainstem Evoked Response Audiometry (BERA). Analisis statistik menggunakan uji chi-square dengan tingkat signifikansi p < 0,05. Hasil:Rerata usia responden adalah 7,45 ± 3,46 tahun, dengan mayoritas berusia 7–14 tahun (61,3%) dan berjenis kelamin laki-laki (64,5%). Sebagian besar memiliki berat badan lahir normal (74,2%) dan lahir cukup bulan (83,9%). Hasil timpanometri menunjukkan tipe A pada 83,9% telinga kanan dan 87,1% telinga kiri. Pemeriksaan OAE menunjukkan 71% pass dan 29% refer. Hasil BERA menunjukkan 71% normal, 25,8% mengalami gangguan pendengaran sensorineural (SNHL), dan 3,2% gangguan campuran.

The Impact of Macroprudential Policies on the Stability of the Banking System in Indonesia
No full textThe stability of the banking system is a crucial pillar in maintaining national
economic resilience, especially amid ongoing global economic fluctuations. In this
context, macroprudential policies have become essential instruments implemented
by monetary authorities such as Bank Indonesia. This study aims to analyze the
impact of macroprudential policies, represented by Loan to Value (LTV), Reserve
Requirement (GWM), and Capital Adequacy Ratio (CAR), on the stability of the
banking system in Indonesia, as measured by the Z-Score. In addition, this study
includes control variables such as Return on Assets (ROA) and bank size (Size) to
enrich the analysis.
The data used is secondary panel data obtained from 25 publicly listed
conventional commercial banks in Indonesia during the period of 2014–2023. The
study employs dynamic panel regression analysis using the Generalized Method of
Moments (GMM) to address potential endogeneity issues. The findings indicate that
LTV has a negative and significant effect on the Z-Score, while both GWM and CAR
have positive and significant impacts. Bank size also shows a positive and
significant relationship with banking stability, whereas ROA exhibits a positive but
statistically insignificant effect.
These results suggest that strengthening liquidity and capital buffers
through macroprudential instruments can enhance banking system resilience, while
excessive credit expansion poses risks to stability. Therefore, this research
recommends that monetary authorities continue to reinforce supervisory
mechanisms and adjust policies in line with economic conditions. The study is
expected to contribute to evidence-based policymaking aimed at ensuring financial
system stability in Indonesia.100 PagesSkripsi Sarjan
Analysis of Sanitary Hygiene and Fly Density of Chicken Meat Sellers at Simpang Limun Market Medan City
No full textTraditional markets are strategic locations for the transmission of environment-based diseases, particularly through the sale of food products such as broiler chickens. Meat is an ideal medium for bacterial growth due to its high water content, abundance of nitrogenous substances, and minerals, which support microbial proliferation. Contamination in chicken meat can occur due to poor personal hygiene of sellers and unsanitary sales environments. Poor hygiene and sanitation conditions contribute to an increased population of disease vectors, such as flies, which can contaminate food and endanger public health. This study aims to analyze personal hygiene, sanitation, and fly density among broiler chicken sellers at Simpang Limun Market in Medan City. This is a descriptive study using observational and interview methods. The sample consisted of 40 chicken meat sellers selected through total sampling. Results showed that the majority of the sellers were male (82.5%), aged 26-35 years (32.5%), graduated from high school (47.5%), had worked for 1-5 years (50%), and were generally not suffering from infectious diseases (92.5%). Most sellers had good personal hygiene (95%). Sanitation conditions among sellers without live chickens mostly did not meet the requirements (80%), while those with live chickens mostly met the requirements (60%). Fly density measurements indicated high fly density at broiler chicken stalls. It is recommended that sellers improve their behavior, particularly waste disposal and stall cleanliness, as well as sanitation practices, including equipment cleanliness, waste bin availability, and waste channel maintenance. It is also recommended that the relevant government authorities improve and provide adequate market sanitation facilities, such as regular disinfection.

Synthesis and Characterization of Superabsorbent Polymers Based on Sodium Carboxymethyl Cellulose and Hydroxyethyl Methyl Cellulose with Citric Acid as a Crosslinking Agent
No full textThis study investigates the synthesis and characterization of polymer superabsorbents (SAP) based on sodium carboxymethyl cellulose (Na-CMC) and hydroxyethyl methyl cellulose (HEMC). The synthesis of polymer superabsorbents was carried out by mixing Na-CMC and HEMC using a mass ratio of 3:1 in a 2% mass mixture. In the next stage, citric acid was added as a cross-linking agent using varying concentrations of 2%, 3%, 4%, and 5%. The resulting mixture formed a film that was characterized using cross-linking degree testing, water absorption testing, FTIR, DSC, and TGA. The best crosslinking percentage was observed at a citric acid concentration of 3%, yielding 82.10%. The water absorption results showed an optimum value with a 3% citric acid concentration, which could absorb 7.184%, or 359.2 g/g of its dry weight. The FTIR test results showed the formation of SAP, supported by the FTIR spectrum in the mixture of Na-CMC, HEMC, and citric acid as cross-linking agents, with the presence of –OH groups at a wavelength of 3382.1 cm-1 and –COO groups at a wavelength of 1416.4 cm-1, and a new absorption peak at a wavelength of 1687.8 cm-1 indicating the presence of ester groups, which indicates that cross-linking has occurred in the SAP. The results of the thermogram analysis using DSC yielded a glass transition temperature (Tg) value between 109.0 °C, which is between the Tg of Na-CMC and HEMC, namely the Tg of Na-CMC at 148.03 °C and the Tg of HEMC at 113.82 °C. This indicates that there has been polymer network interaction between the three samples. The TGA test was conducted to assess thermal stability, and the results showed that SAP Optimum 3% has better thermal stability compared to Na-CMC67 PagesSkripsi Sarjan
