This study aimed to investigate the potential use of brown algae Sargassum polycystum as irreversible hydrocolloid (alginate) impression material. Potassium alginate extracted from Sargassum polycystum was prepared in three different compositions (14%, 15%, and 16%) and mixed with other standard components to form an alginate impression material. Prior to that, the purity of potassium alginate was quantified with Fourier Transform Infrared Spectroscopy (FTIR) analysis. As a control material, the alginate impression material from a commercially available product was used. All alginate impression materials were then applied to a die stone model. Dimensional accuracy was measured by calculating the mesiodistal width of incisors in the generated dental cast using a digital caliper 0.01 accuracy (five replications). In addition, to evaluate the dimensional stability, the impression results were poured at four different periods (immediately, 5 min, 10 min, and 15 min). An independent t-test was performed to compare the measurement results with p < 0.05 considered significant. Analytical results confirm that the impression material containing 15% potassium alginate gives the best dimensional accuracy similar to control (p > 0.05). Meanwhile, the optimal dimensional stability was produced in the impression material containing 16% potassium alginate. Our study suggested that brown algae Sargassum polycystum has a promising potential to be used as an alginate impression material in clinical application.

Background/objectives: Oral lichen planus (OLP) is a chronic autoimmune disorder affecting various age groups and is associated with multiple factors. Conventional therapies often encounter complications from opportunistic infections, particularly oral candidiasis. This study examines the relationships between Candida colonization and oral microbiome composition in OLP patients. Through meta-analysis, we clarify these interactions and their implications for OLP progression. Methods: The PICOS is a systematic research strategy, following PRISMA 2020 and MeSH descriptors: oral lichen planus, oral microbiome, oral fungal, and non-Candida oral fungal. Results: A search of CINAHL, EMBASE, PubMed, Science Direct, and Web of Science identified 313 studies. Twelve studies were suitable for a systematic review, with four appropriate for meta-analysis. Findings showed a significant association between OLP and oral microbiota, with an OR of 4.155 (95% CI: 1.278–13.511, p = 0.024). Although analyses of C. albicans and non-albicans species lacked significance, particular non-albicans species were noted. The subgroup analysis of oral microbiota approached significance, indicated by an OR of 11.739 (95% CI: 0.654–210.713, p = 0.059). Conclusions: This study highlights the roles of Candida species and the oral microbiota in OLP, revealing a complex interaction between Candida colonization and the oral microbiome.

The provision of complementary feeding (MP-ASI) is one of the important periods in the first thousand days of a child's life. The transition period, which takes place at the age of 6 months to 24 months, is quite vulnerable for children's growth. The selection of quality MP-ASI is influenced by the mother's level of knowledge about food ingredients and the nutritional adequacy of the baby. Although instant MP-ASI is now easy to obtain, complete with information on nutritional values, the percentage of the Nutrient Adequacy Rate (RDA) for each baby is different, depending on the baby's weight, age and type of allergy. So that more knowledge is needed to determine the right MP-ASI menu according to the nutritional needs of infants. With these problems, the author makes a web-based MP-ASI menu recommendation information system, which uses the PHP programming language, and the MySQL database. The algorithm method used to determine the MP-ASI menu recommendations according to the nutritional needs of infants is the Forward Chaining method, while the system testing method uses white box testing. The purpose of this study is to make it easier for mothers to choose the right MP-ASI menu recommendation system and information about MP-ASI that can be accessed by users through the website, where all data on the system is managed by the admin on a different website from the website that can be accessed by users. users. With this system, it is hoped that it can help the community to get the right MP-ASI menu recommendations.

Udang vaname (L. vannamei) adalah komoditas yang berkembang pesat dengan keunggulan pertumbuhannya cepat, dan mempunyai harga pasar yang cukup tinggi dan secara ekonomi udang vaname memberikan kontribusi terhadap nilai ekspor hasil produksi perikanan di Indonesia yaitu sebesar 33,1%. Upaya yang dipenuhi untuk kebutuhan konsumsi yang berkualitas maka dibutuhkan pengelolaan teknis dan sumberdaya yang mencukupi serta diperlukannya teknologi yang tepat. Seiring berkembangnya teknologi, udang vaname (L. vannamei) telah dikembangkan dengan sistem intensif dan supra intensif. Salah satu potensi tambak di Indonesia adalah PT Suri Tani Pemuka, yang merupakan salah satu perusahaan yang aktif dalam memproduksi dan pengembangan budidaya udang yang telah menerapkan teknologi intensif. Pengamatan ini dilaksanakan di PT Suri Tani Pemuka, Banyuwangi pada tanggal 2 September sampai dengan 30 Oktober 2019. Tujuan pengamatan adalah mengevaluasi aspek teknis, performansi kinerja budidaya udang vaname, aspek finansial dan identikikasi masalah. Metode observasi dan wawancara digunakan untuk mengumpulkan data primer maupun sekunder. Aspek teknis dan performansi kinerja budidaya udang vaname di PT STP belum mencapai standar yang berlaku yang diterapkan oleh perusahaan yaitu rata-rata produkttivitas 82%, SR 78%, FCR 58%, ABW 0%, dan ADG 66%

Objective: to assess awareness of senior community in the Belawa distric, Wajo, South Sulawesi, Indonesia regarding their oral soft tissue abnormality specifically regard to Oral potentially malignant disorders, and to assess community ability to descript any pain or uncomfortably origin from their oral cavity. Methods: A self-made questionnaire written in Indonesia language was given to the old aged-adult based on WHO criteria with age range between 45 to 75 years old, who was willing to participate in this study. The questioner consists some picture representing oral mucosal cavity with clinical feature of some ulcers, clinical feature of candida infection, and some clinical appearances of oral potentially malignant disorders. Results: In term of oral mucosal diseases questions, 22 (55%) participants had history of ulceration, however only 5 (45%) participants could specifically point out its previous ulcer location. However, history of pain only stated by 11 (28%) participants, 24 (60%) did not experienced any pain, and 5 (12%) did not answer the questions. Conclusion: knowledge and awareness regarding oral health lesion, especially the associated-potentially malignant lesion was far from ideal in the Belawa Community.

Budidaya udang vaname menjadi primadona di Indonesia karena memiliki nilai komersil dan memberikan pendapatan bagi negara. Teknologi pemberian pakan salah satu faktor untuk keberhasilan budidaya. Saat ini teknologi berbasis IoT yaitu automatic feeder yang sedang tren pada budidaya udang vaname. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan automatic feeder pada budidaya udang vaname. Penelitian dilaksanakan pada bulan Maret-Mei 2021 di PT. Windu Marina Abadi, Lombok Timur dengan pengukuran pertumbuhan, kelangsungan hidup, dan FCR serta menganalisis kualitas air. Hasil penelitian menunjukkan pertumbuhan berat terendah terdapat pada petak A5 (7,79 g) dan tertinggi B5 (18,14 g) dengan rata-rata laju pertumbuhan perhari terendah yaitu A5 (0,09) dan B5 (0,21 g), kelangsungan hidup pada tambak menggunakan automatic feeder mencapai 97%, FCR tertinggi yaitu pada tambak (manual) A5 (2,45) dan terendah pada tambak B6 (automatic feeder) (1,08). Nilai kualitas air masih kisaran normal untuk budidaya. Tambak dengan penggunaan automatic feeder relatif lebih baik dibandingkan dengan tambak dengan pemberian pakan secara manual.
