The Effects of Nano-Chitosan Hydroxyapatite, CPP-ACP, and Silver Diamine Fluoride on Enamel Remineralization: A Qualitative and Quantitative In Vitro Study
No full textDental caries is one of the most common oral health problems globally, including in Indonesia. The initial indication of dental caries is the presence of non-cavitated lesions or white spot lesions (WSL). Demineralization is the primary cause of WSL formation. The mechanisms of demineralization and remineralization of Ca and P ions involve a series of chemical processes occurring in the enamel. When the oral pH drops below 5.5, H+ ions from dietary acids and bacteria cause enamel demineralization, leading to the release of Ca and P ions from hydroxyapatite. Conversely, remineralization involves the binding of Ca and P ions to demineralized enamel areas. This issue can be addressed by applying materials that promote enamel remineralization, such as chitosan. The purpose of this study is to compare the effectiveness of nano-chitosan hydroxyapatite, CPP-ACP, and SDF as remineralization agents using SEM-EDX analysis and to compare enamel hardness values using the Vickers hardness test. A total of 30 tooth sections obtained from the splitting of molar teeth were divided into four groups. Group I received CPP-ACP application. Group II received SDF application. Group III received nano-chitosan hydroxyapatite application. Statistical analysis showed no significant differences in calcium and phosphorus content among the groups (p > 0.05). Qualitative analysis using SEM revealed differences in the enamel surface morphology after remineralization. The enamel surface hardness test results indicated a significant difference in hardness values between the CPP-ACP and SDF groups (p = 0.014). In conclusion, there are variations in the effectiveness of each material, and all three remineralization agents demonstrate potential in restoring demineralized enamel structure96 PagesSkripsi Sarjan

No full textAquaculture are very dependent on the availability of feed in sufficient
quantity and good quality to assist in the fish growth process. It is known that male
gourami fish (Osphronemus gouramy) grow faster so that it can increase production
from growing gourami fish. One of the aquaculture biotechnologies that has been
widely developed and applied in increasing aquaculture production, especially fish
through masculinization, is sex reversal. This method is carried out orally by adding
Brahman cattle testicle flour (Bos indicus) to commercial feed at different doses.
The aim of this research is to determine the dominant gender by using cow testicle
meal for the Sex Reversal process in Gourami Fish (Osphronemus gouramy) and to
determine the effect of the interaction between mixing commercial feed and cow
testicle meal used on sex formation in gourami fish larvae (Osphronemus gouramy).

Utilization of Social Capital by Traditional Market Traders in Maintaining and Advancing the Business (Study in Gambir Market, Percut Sei Tuan District, Deli Serdang Regency)
No full textTraditional markets play a crucial role in the community's economy, primarily as
distribution centers for essential goods and as social interaction spaces between
traders and buyers. However, their existence is increasingly threatened by
competition from modern markets and e-commerce. In this situation, social capital
becomes a strategic factor that can help traders sustain and grow their businesses.
This study aims to analyze the utilization of social capital by traders at Pasar
Gambir, Percut Sei Tuan District, Deli Serdang Regency, focusing on three main
elements: trust, norms and values, and social networking. The study employs a
qualitative approach with a case study method. Data was collected through in-depth
interviews, direct observations, and documentation. The data analysis technique
was conducted using a descriptive-interpretative approach to understand the
interaction patterns and strategies traders use to leverage their social capital. The
results indicate that trust is a key element in maintaining customer loyalty. Traders
who uphold product quality, apply transparent pricing, and ensure accurate
measurements gain the trust of buyers, leading to increased sales. Additionally,
social values and norms such as honesty, friendliness, and solidarity among traders
play a significant role in fostering harmonious relationships. The norm of mutual
cooperation also enables traders to assist one another, both in terms of capital and
business information. A strong social network, both among traders and with
suppliers, provides advantages in securing stock at more competitive prices and
reaching a broader customer base. However, the study also identifies several
challenges, including changing consumer preferences, price competition with
modern markets, and market infrastructure limitations that may hinder the
optimization of social capital. This study emphasizes that social capital is a
valuable asset for traders in sustaining and expanding their businesses. Therefore,
support from the government and trader associations is needed to strengthen social
capital through policies that promote the sustainability of traditional markets.
