Abstract

Kesehatan rongga mulut merupakan bagian penting dari kesehatan secara menyeluruh. Gigi merupakan salah satu organ pencernaan paling penting dalam proses pencernaan makanan, sehingga kesehatan gigi merupakan salah satu hal terpenting bagi pertumbuhan anak. Tingginya resiko karies gigi pada anak-anak disebabkan karena secara fisiologis-anatomi gigi sulung mempunya pit dan fissure yang lebih dalam sehingga memudahkan plak menempel. Selain itu, konsumsi gula yang tinggi pada anak-anak memicu proses terjadinya kerusakan gigi (Suwelo, I.S. 1992). Anak-anak berkebutuhan khusus merupakan kelompok berisiko tinggi terhadap masalah kesehatan sehingga membutuhkan bantuan dan kerjasama dengan orang lain untuk mendapatkan dan memelihara kesehatan, termasuk dalam menjaga kesehatan gigi dan mulut mereka. Kondisi gigi dan mulut yang bersih dan sehat sangat penting untuk menunjang kehidupan anak-anak tersebut. Masalah gigi yang biasanya muncul pada anak berkebutuhan khusus antara lain karies (lubang) gigi, gigi berdarah, dan gigi berjejalan (maloklusi). Oleh karena itu, anak-anak berkebutuhan khusus lebih membutuhkan perhatian dibandingkan anak-anak normal lainnya karena berbagai keterbatasan yang dimiliki terutama kurang mampu untuk membersihkan sendiri rongga mulutnya. Sehingga hal ini meningkatkan faktor resiko kerusakan gigi-gigi dan jaringan lunak rongga mulut disekitarnya. Penelitian ini bertujuan untuk mengetahui tingkat kebersihan rongga mulut dan status kesehatan rongga mulut serta hubungan antara tingkat kebersihan rongga mulut dengan status gingivitis/penyakit periodontal pada siswa autis. Jenis penelitian ini adalah anayitic correlation dengan pendekatan cross sectional, sampel diambil menggunakan teknik accidental sampling dengan uji statistik Kolmogorov-Smirnov. Subjek adalah 35 siswa autis di SLB Autis dan TPA B SLB Branjangan Kabupaten Jember. Hasil penelitian menunjukkan tingkat kebersihan mulut siswa autis di SLB Branjangan sebagian besar adalah sedang (57,1%) dan sebagian besar siswa yang diperiksa mengalami karies dan penyakit periodontal sedang (70%). Semua siswa yang diperiksa mengalami karies, baik itu siswa dengan tingkat kebersihan mulut yang baik, sedang maupun buruk. Disarankan kepada siswa autis tersebut untuk selalu menjaga kebersihan dan kesehatan rongga mulutnya.

Abstract

The current energy crisis momentum is the right time to redesign energy policy; otherwise, the energy deficit will continue and influence economic activities. For this reason, this research took Central Java Province as a case study. This research aims to estimate energy demand, the dominance of energy use, and energy efficiency. In this study, energy demand was modeled by sector using the intensity approach to calculate the energy used per activity unit. Low Emissions Analysis Platform (LEAP) model was then utilized to figure out future trends in energy demand and energy structure from 2015 to 2030 under different scenarios, including Business as Usual (BAU), Moderate (MOD), and Optimistic (OPT) scenarios. The results uncovered that energy demand in Central Java has grown by 5.6% per year, and the overall final energy demand is 1,683,091.24 thousand BOE. In this case, the transportation and household sectors are the largest and second-largest consumers, while premium and electricity are the dominant components in this province. In addition, efficiency energy could be achieved in 2021 and 2017, respectively, under the MOD and OPT scenarios. From the utilization of renewable energy, Central Java also contributes 1.17% to the utilization of renewable energy nationally. Overall, this research provides important insights and highlights possible steps for policymakers in developing energy efficiency policies.

Abstract

ABSTRACTIntroduction: Green tea leaves are abundant in bioactive components, including catechins, flavonoids, and polyphenols. These compounds are known for their antibacterial, anti-inflammatory, and antioxidant properties. In addition, green tea also contains minerals, such as Calcium, Phosphor, Potassium, Magnesium, and Sulphur. However, the precise mineral content and anti-bacterial properties of green tea against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans from Gunung (Mount) Gambir in Jember Regency are currently unknown. This study aimed to analyze the phytochemical composition and antibacterial activity of green tea leaf extract from Gunung Gambir, Jember against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Methods: The bioactive constituents of green tea leaf extract were identified using a UV-Vis spectrophotometer to measure its total flavonoid content (TFC) and total phenolic compounds (TPC). Mineral identification was performed using flame atomic absorption spectrometry. The disc diffusion method was used to assess antibacterial activity by quantifying the diameter of the inhibition zone in cultures of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans treated with green tea leaf extract at concentrations of 3.125%, 6.25%, 12.5%, 25%, 50%, and 100%.  Anaerobic conditions were created by incubating the Petri dishes in a desiccator for 24 hours at 37°C. One-Way Anova test was used to analyze the data, and differences were considered statistically significant at p<0.05. Subsequently, a LSD test was carried out (p<0,05). Results: The TPC value was 1.607±0.742 mg GAE/g, while the TFC value was 99.146 ± 0.307 mg GAE/g. Calcium appeared to be the most abundant mineral in the tea extract, measured at 31.65 ppm. The inhibitory power of green tea leaves extract against both bacteria was not significantly different (p>0.05). Conclusion: Green tea leaves extract from Gunung Gambir Jember Regency in Indonesia is rich in phenolic compounds, flavonoids, and certain minerals, such us Phosphor, Calium, Magnesium, Sulphur and Calcium. These constituents are known to possess biological and antibacterial activity against Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans.KEYWORDS Antibacterial, flavonoid, green tea extract, minerals, phenol, Jember

Abstract

Periodontitis is an inflammatory disease of the tooth supporting tissues caused by pathogenic microorganisms in dental plaque. P. gingivalis as the main etiology of periodontitis has a virulence factor in the form of lipopolysaccharide (LPS). The use of NiTi wires in initial orthodontic treatment can exacerbate periodontitis. Robusta coffee beans contain active compounds such as chlorogenic acid, caffeic acid, ferulic acid and caffeine as anti-inflammatories and antioxidants. This study aims to analyze the ability of robusta coffee bean extract gel to reduce TRAP in a rat model of periodontitis induced by the combination of LPS P. gingivalis and NiTi wire. The 28 male wistar rats were classified into 7 groups of normal (K), injected with LPS (P1), NiTi wire (P2), combination of LPS and NiTi wire (P3), injected with LPS and 500 mg/ml robusta coffee bean gel (P4), NiTi wire and 500 mg/ml robusta coffee bean gel (P5), combination of LPS and NiTi wire with 500 mg/ml robusta coffee bean gel (P6). The rats were decapitated, and then the tissue was stained with HE and IHC. The expression of TRAP was counted in the area around alveolar bone of the lower-left M1. Data were analyzed using SPSS software by going through several test, such as Saphiro-Wilk, Levene-Test, Kruskal-Wallis, and followed by Mann-Whitney. The results of TRAP expression showed a significant decreased (p<0,05) on combination of LPS and NiTi wire with robusta coffee bean extract gel. Robusta coffee bean extract gel was able to reduce TRAP expression on periodontitis model rats induced by the combination of LPS P. gingivalis and NiTi wire.

Abstract

The development of renewable energy is essential amid the global energy transition, yet the sustainability of solar power plants—both commercial and household—in Bali Province remains low. Access to electricity is a vital component of sustainable development, helping to bridge the gap between rural and urban areas in Indonesia. In 2016, solar power plants were established in Karangasem Regency to electrify rural communities that previously lacked access due to difficult geographical conditions. This study aims to identify and analyze the key factors influencing sustainable solar power growth in Karangasem while offering strategic recommendations. Employing a qualitative approach and the MICMAC method, it explores economic aspects such as job creation, poverty alleviation, and energy investment; social factors like energy access and community participation; environmental considerations including waste management and climate mitigation; and institutional elements involving local regulations and public-private collaboration. The findings highlight that fostering local economic development (ESD), sustainably managing resources (SNRU), and reducing air pollution (AP) are crucial for enhancing environmental quality (EQI) and attracting investment (EI). The study emphasizes the need for collaborative frameworks and robust policy measures to promote renewable energy, ensuring long-term sustainability and advancing rural development and environment in Karangasem Regency, Bali Province.

Abstract

The regional approach aims to identify, analyze and evaluate the extent of regional development carried out by local governments, as well as to achieve regional development whether it is in accordance with the characteristics of the region. Bogor Regency plays an important role as a buffer area for DKI Jakarta. The high regional development and economic growth of DKI Jakarta has caused high population growth and high economic growth in Bogor Regency. However, the high economic growth does not guarantee economic equality in the region. The purpose of this study is to analyze and map regional development in Bogor Regency based on regional hierarchy and analyze the extent of equitable distribution of economic activities in Bogor Regency. The analsysis method used is using Regional Hierarchy Analysis and Overlay by Geographic Information System. The data used in this study used data on Gross Regional Domestic Income (GRDI). The results showed that the Regional Development Index in Bogor Regency in total continued to increase. However, if observed, the value of the coefficient of variation shows a significant increase. This shows an increase in inequality during that period of 32.057 percent.
