Lactobacillus plantarum FNCC-0461 merupakan bakteri asam laktat yang diisolasi dari dadih, yang berpotensi sebagai probiotik. Probiotik menunjukkan manfaat jika memiliki viabilitas minimal 1 x 10⁷ CFU di ileum distal atau kolon. Namun, sebagian besar probiotik tidak tahan terhadap kondisi ekstrim selama melalui saluran cerna. Enkapsulasi probiotik menjadi sediaan pelet tertarget kolon menjadi solusi yang baik untuk menjaga viabilitas dan memberikan pelepasan probiotik ke lokasi spesifik di kolon. Pelet diformulasikan menggunakan metode ekstrusi-sferonisasi dengan eksipien berupa Microcrytalline Cellulose (MCC), laktosa, pektin, Cellulose Acetate Phthalate (CAP) dan shellac. Sediaan pelet yang telah dibuat dievaluasi karakteristik fisik, viabilitasnya hingga dilakukan uji disolusi selama 24 jam pada pH 1,2; 6,8 dan 7,4. Pelet yang dilapisi CAP menunjukan hasil yang paling optimum dengan karakteristik pelet yang berbentuk bulat dengan distribusi ukuran partikel 913,57 ± 8,28 μm dan persen perolehan kembali 88,71 ± 1,04 % yang memiliki sifat alir yang sangat baik, kekuatan mekanik yang baik, viabilitas 4,76 x10⁷ CFU/g dan hasil uji disolusinya menunjukan pelepasan sel tertinggi pada cairan simulasi kolon sebesar 1,38 x 10⁷ CFU/g setelah 24 jam. ......Lactobacillus plantarum FNCC-0461 is a lactic acid bacteria isolated from dadih which has potential as a probiotic. Probiotics show health benefits if they have viability at least 1 x 10⁷ CFU in the distal ileum or colon. However, most probiotics are not resistant to extreme conditions while passing through the digestive tract. Encapsulation of probiotics into colon-targeted pellets was a good solution to maintain the viability and provide release of probiotics to specific site in the colon. Pellets were formulated using extrusion-spheronization method with excipient such as Microcrystalline Cellulose (MCC), lactose, pectin, Cellulose Acetate Phthalate (CAP) and shellac. The obtained pellets were evaluated for their physical properties, viability and dissolution study was carried out at pH 1.2; 6.8 and 7.4 for 24 hours. CAP-coated pelet provide the optimum formulation were spherical with particle size distribution was 913.57 ± 8.28 μm and yield was 88.71 ± 1.04 %, it’s have very good flow properties, good mechanical properties, viability was 4.76 x10⁷ CFU/g and it’s dissolution study showed the highest cell release in simulated colonic fluid of 1.38 x 10⁷ CFU/g for 24 hours.

Latar Belakang: Candida albicans merupakan penyebab utama infeksi mikroba oportunistik pada pasien kanker. Pasien Leukemia Limfositik Akut (LLA) yang menjalani kemoterapi memiliki risiko tinggi terkena kandidiasis karena imunosupresi dan melemahnya barier epitel. Penggunaan obat antifungal sistemik dibatasi oleh risiko efek samping yang lebih besar dan berkembangnya strain yang resisten, namun obat antifungal topikal yang tersedia saat ini masih dianggap kurang efektif untuk pasien imunosupresi termasuk pasien kemoterapi. Beberapa penelitian memberikan bukti kelayakan probiotik Lactobacillus casei untuk bertindak sebagai antifungal alternatif di berbagai sistem organ manusia. Tujuan: Menganalisis pengaruh probiotik terhadap jumlah C. albicans di rongga mulut anak penderita LLA selama kemoterapi. Metode: Sampel saliva diambil dari 11 anak penderita LLA selama kemoterapi. Subyek diinstruksikan untuk berkumur dengan probiotik yang mengandung L. casei selama 60 detik, dua kali sehari, selama 14 hari. Sampel saliva tidak terstimulasi dikumpulkan secara berurutan pada 3 titik waktu (awal, 7 hari, dan 14 hari). Jumlah C. albicans dihitung dengan qPCR. Hasil: Perbedaan signifikan secara statistik ditemukan antara jumlah C. albicans pada awal (494.363+180.737 CFU/ml), setelah 7 hari (276.654+69.903 CFU/ml), dan setelah 14 hari (229.286+50.883 CFU/ml) berkumur dengan probiotik. Jumlah yang lebih rendah secara signifikan ditemukan setelah 7 dan 14 hari berkumur dengan probiotik (p<0.05). Kesimpulan: Probiotik L. casei memiliki efek menurunkan jumlah C. albicans di rongga mulut anak leukemia selama kemoterapi. ......Background: Candida albicans is the leading cause of opportunistic microbial infections in patients with cancer. Acute Lymphocytic Leukemia (ALL) patients undergoing chemotherapy have high risk of candidiasis due to immunosuppression and weakened epithelial barriers. Systemic antifungal drugs’ usage is limited by the greater risk of side effects and developing resistant strains, yet currently available topical antifungal drugs are still considered ineffective for immunosuppressed patients including chemotherapy patients. Several studies provide evidence for the feasibility of probiotic Lactobacillus casei to act as alternative antifungal in various human organ systems. Objectives: To analyze the effects of probiotic L. casei on the number of C. albicans in oral cavity of children with ALL during chemotherapy.Methods: Saliva samples were taken from 11 children with ALL during chemotherapy. Subjects were instructed to do mouth rinse with probiotics contained Lactobacillus casei for 60s, twice daily, over the course of 14 days. Unstimulated saliva samples were collected sequentially at 3 time points (baseline, 7 days, and 14 days). The number of C. albicans was quantified by qPCR. Results: Statistically significant differences were found between the number of C. albicans at baseline (494.363+180.737 CFU/ml), after 7 days (276.653+69.903 CFU/ml), and after 14 days (229.286+50.883 CFU/ml) mouth rinsing with probiotic L. casei. Significant lower number was found both after 7 and 14 days rinsing with probiotics (p<0.05). Conclusion: Probiotic L.casei has reducing effects on the number of C. albicans in oral cavity of children with ALL during chemotherapy.

ABSTRAK
Ekstraksi Asbuton secara biologis terhadap CaCO3 sebagai pengotor utama Asbuton dilakukan dengan dua tahap. Tahap pertama glukosa dikonversi menjadi asam laktat oleh bakteri Lactobacillus acidophilus FNCC 0051 melalui proses fermentasi selama 24 jam pada suhu 37oC. Tahap kedua proses bioleaching CaCO3 berlangsung saat asam laktat bereaksi dengan CaCO3 menjadi kalsium laktat. Tingginya kandungan umpan glukosa dan besarnya kecepatan agitasi mempengaruhi kemampuan bakteri mereduksi padatan karbonat. Keberadaan kalsium laktat, CaCO3 dan aspal diuji menggunakan FTIR. Hasil penelitian menunjukkan bahwa kandungan glukosa yang tinggi dengan kecepatan agitasi yang rendah mampu menghasilkan CaCO3 terlarut sebesar 0,3188%. Kandungan CaCO3 pada ekstrak bitumen berkurang menjadi 19,67% dari 43,28% pada 150 rpm dengan umpan glukosa 12 % (b/v).

Simpulan: Pemberian probiotik Lactobacillus acidophilus dengan GRV tidak mempunyai efek hubungan dibandingkan dengan placebo. ......Background: Laparotomy is a surgical procedure that affects gastrointestinal motility. Research by Cihoric et al showed that 12.5% ​​of post-laparotomy patients experienced complications of gastrointestinal dysfunction. Dysfunction in gastrointestinal motility is a frequent complication of abdominal surgical procedures. Out of 100 patients with digestive laparotomy surgery, it was found that as many as 40% of patients in the ICU experienced an increase in gastric residual volume in postoperative digestive laparotomy patients. Supplementation with Lactobaciillus acidophilus is known to increase gastric motility. Aim: This study aims to determine the effect of the relationship between administration of Lactobacillus acidophillus probiotics and GRV. Methods: The study design used was an experimental or double-blind randomized clinical trial. A total of 55 subjects who followed the randomization, 54 subjects who would undergo gastrointestinal laparotomy were included in the study, 1 subject dropped out due to sepsis. Research subjects were given probiotic capsules Lactobacillus acidophilus 109 (probiotic group) or given lactose capsules (placebo group) for 3 days before surgery. GRV levels were measured 2 days after the procedure. Results: Of the 54 subjects with 27 subjects in each group, they followed the research to completion. On the first day (24 hours), the 24-hour GRV with the administration of probiotics and the control group showed insignificant results (p value 0.669). On day 2 (48 hours), GRV 48 hours with probiotic administration and the control group showed insignificant results (p value 1,000). Results that were not significant at GRV 24 hours and 48 hours could be influenced by confounding factors, geriatrics, history of neurological disorders, obesity, history of vasopressor use, history of consumption of opioids, hypercapnia and hyperglycemia while in the ICU.
