Abstract

Acne is a dysbiotic condition caused by Cutibacterium acnes and Staphylococcus epidermidis bacteria. Gribong (Archidendron clypearia (Jack) I.C. Nielson) has been empirically used as a treatment for facial problems by the people of Bangka Belitung. This study aims to test the potential of ethanol extract and fractions of gribong leaves against two bacteria that cause acne. This study is an experimental research conducted in four stages, namely phytochemical testing, antibacterial activity testing, minimum inhibitory concentration testing, and minimum bactericidal concentration testing and equivalence tests against clindamycin antibiotics as positive controls. The results of this study showed (1) Secondary metabolites contained in 96% ethanol extract, ethyl acetate fraction and n-butanol fraction are phenolics, flavonoids, tannins and saponins. Terpenoids were only found in the ethanol extract. The ethyl acetate fraction found no alkaloids and the n-hexane fraction contained only steroids. (2) The 96% ethanol extract, ethyl acetate fraction and n-butanol fraction had antibacterial activity. (3) The highest antibacterial activity was shown by the ethyl acetate fraction with KHM on C. acnes at 0.375% and on S. epidermidis at 1% and KBM for both bacteria at 2.5%. (4) The equivalence value of antibacterial activity of fractions to antibacterial antibiotic clindamycin is still relatively low but still has good antibacterial activity. In conclusion, the ethanol extract and its fractions have potential as anti-acne against C. acnes and S. epidermidis bacteria.

Abstract

Penelitian ini dilakukan pada ketiga pulau kecil yang ada di Bangka Belitung yaitu Pulau Putri, Pulau Panjang dan Pulau Semujur. Tujuan penelitian ini adalah untuk mengetahui keanekaragaman bivalvia dan gastropoda berdasarkan karakteristik masing-masing pulau. Metode yang digunakan adalah metode Purposive sampling dengan teknik transek garis yang dilakukan pengambilan garis tegak lurus terhadap garis pantai. Stasiun terdiri dari 3 stasiun dengan 5 plot pencuplikan yang dibuat kerangka kuadran berukuran 50×50cm2 dengan jumlah total daerah pencuplikan adalah 15 masing-masing pulau. Analisis data menggunakan rumus keanekaragaman Shannon Wiener. Hasil penelitian menunjukkan bahwa parameter fisik dan kimia pada lingkungan ketiga pulau tergolong baik dengan suhu rata-rata 31,9℃, pH 7,395 dan salinitas 4,15%. Keanekaragaman Gastropoda lebih besar daripada keanekaragaman Bivalvia. Hal ini ditunjukkan dengan adanya 21 spesies gastropoda di Pulau Putri, 18 spesies gastropoda di Pulau Panjang, dan 7 spesies gastropoda di Pulau Semujur sedangkan bivalvia 20 spesies di Pulau Putri, 13 spesies di Pulau Panjang, dan 2 spesies di Pulau Semujur. Famili dari kelas Gastropoda yang paling banyak ditemukan adalah Cerithiidae. Berdasarkan parameter yang diukur pada lokasi penelitian dan adanya perbedaan karakteristik dari ketiga pulau menyebabkan adanya perbedaan keanekaragaman gastropoda dan bivalvia, seperti di Pulau Putri yang didominasi oleh rataan terumbu karang yang sangat luas dan rapat dengan substrat berupa pasir, yang mana kondisi tersebut mempengaruhi tingginya keanekaragaman gastropoda dan bivalvia. Adapun di Pulau Panjang di dominasi oleh ekosistem lamun dengan tipe substrat yang lumpur berpasir, keberadaan lamun dapat menjadi sumber nutrisi serta habitat bagi moluska hal tersebut yang menyebabkan tingginya keanekaragaman gastropoda dan bivalvia. Adapun Kondisi lingkungan di Pulau Semujur di dominasi oleh ekosistem lamun dengan substrat berpasir, serta terdapat pemukiman warga, banyaknya aktivitas seperti rekreasi, memancing dan eksplorasi serta pengambilan fauna untuk koleksi pribadi di Pulau tersebut menyebabkan rendahnya keanekaragaman gastropoda dan bivalvia.

Abstract

Pelawan Bitter Honey and Pelawan Mushroom are typical Bangka biodiversity found in Central Bangka Regency. The Pelawan mushroom grows in Bangka Belitung Islands Province and generally used as a food ingredient and has the potential to be developed as a source of natural immunomodulator agent. Phenolic compounds are known to have immunomodulatory activities that can improve the immune system. In addition, based on preliminary study, honey was also used by local people to strengthen the immune system. The purpose of this study was to identify the content of active compounds from Pelawan honey and Pelawan mushrooms. This research was an experimental study with several stages of testing including phytochemical screening, Thin Layer Chromatography and Extract Standardization tests. The results showed that based on phytochemical test of Pelawan honey contained flavonoids and alkaloids, while based on the Thin Layer Chromatography (TLC) test contained flavonoids and alkaloids. Phytochemical test of Pelawan mushroom showed the existence of Phenolic and Alkaloids, while based on TLC test containing flavonoids with an average Rf value of 0.56.  The standardization of Pelawan mushroom extract produced a total ash content of 28%, drying shrinkage of 40.88 g /mL, specific gravity 0.67 g/mL and water soluble extract content of 59.01% and ethanol soluble extract content of 41.12%. From these results, it can be assumed that the pelawan honey and pelawan mushroom have the potential to be developed as immunomodulatory agent.

Abstract

Freshwater lobster (Cherax quadricarinatus) is one of the freshwater commodities that has the potential to be cultivated and has economic value. However, the problem still faced by farmers is the quality of feed which can affect low growth and survival. This research aims to analyze the growth performance of juvenile lobsters fed silk worms and rice flour. This research used 30 juvenile lobster samples measuring 1-3 cm (+ 1 inch) that were around 30 days old per aquarium. The parameters observed were body length, body weight, and survival rate (SR) of juvenile lobsters and the water parameters measured were pH, temperature, and total dissolved solids (TDS). The results of the research show that juvenile freshwater lobsters are able to consume silk worms and rice flour so that juvenile lobsters can be classified as omnivores. Feeding treatment in the form of a combination of silk worms and rice flour showed the best results for growth in length, weight and SR of juvenile freshwater lobsters. Juvenile growth during 32 days of rearing fed a combination of silkworm and rice flour resulted 4.30 cm + 0.02 cm in a length, 1.43 g + 0.01 g in weight, and SR 80%.

Abstract

Bangka Belitung Province is one of the largest tin producing area in Indonesia. One of the mining sites located on the Sampur Beach, Kebintik Village, Central Bangka Regency. Tin mining activities can increase heavy metals harmful to the environment, such as Cadmium (Cd). This research aimed to measure Cd levels in sediment and seawater, to isolate and identify Cd resistant bacteria from sediment. Cd metal was analyzed using Atomic Absorption Spectrophotometer (AAS). The average Cd metal level in seawater is 0,0080 ppm and in sediment is 0,0086 ppm. Bacteria were isolated using Zobell 2216E media with the spread plate method. The isolated Bacteria were tested for resistance to Cd with concentration of 20 ppm, 50 ppm, 80 ppm, 100 ppm, and 120 ppm. From 16 bacterial isolates that have been obtained, 7 isolates were resistant to all concentrations, 1 isolate was resistant to 50 ppm, 1 isolate was only resistant to 20 ppm, and 7 isolates were not resistant. Based on the results of the analyzed, the seven isolates of resistant bacteria have similarity with Halomonas sp. (R2 and R3), Neisseria sp. (R4), Cupriviadus sp. (R5), Bacillus sp. (R11), Alcaligenes sp. (R12), and Roseobacter sp. (R13).

Abstract

This study aimed to determine the level of feed consumption, weight gain of cattle, and to calculate the population of lactic acid bacteria (LAB) and pathogenic bacteria Escherichia coli and Salmonella in cattle feces in order to determine the effect of giving probiotics on the digestive system of cattle. The research object used was 10 bali cattle with a weight of about 90-120 kg. The data in this study were analyzed by experimental design using analysis of variance to determine the effect of giving probiotics to cattle feed on cattle weight gain. The treatment in question includes G0 with treatment in the form of feeding with a composition of 60% forage, 15% palm cake, 25% cassava, and 100 ml molasses. Meanwhile, G1 was treated with the same feed as G0, but added with 100 ml of probiotic Probio_FM. Based on the results of the study, it is known that probiotics given to cattle feed showed no significant effect on the level of feed consumption and body weight of cattle where cattle with non-probiotic feed had a higher average consumption level than cattle on probiotic feed. Furthermore, this causeed the average weight gain of non-probiotic cattle to be higher than that of probiotic cattle. In addition, it was known that the population of Lactic Acid Bacteria in the feces of probiotic cattle showed a higher number of LAB colonies compared to non-probiotic cattle with numeric values of 3.6x108, 3.3x109, and 2.7x1010. This proved that giving probiotics to bali cattle with a concentration of 100 ml / 100 kg of feed was able to increase the concentration of lactic acid bacteria in the digestive system.

Abstract

Porang tubers (Amorphophallus sp.) are a food commodity rich in glucomannan but also contain antinutritional compounds such as calcium oxalate. This study aimed to determine the effect of adding Saccharomyces cerevisiae yeast on improving the quality of porang flour and its ability to reduce calcium oxalate content. The research method used was fermentation with the addition of various concentrations of S. cerevisiae. The treatments applied were soaking with 10% S. cerevisiae, 20% S. cerevisiae, and a control treatment without yeast (0%). Parameters observed during the fermentation process included pH, total acidity, and total population in the porang soaking water. Meanwhile, yield, calcium oxalate, glucomannan, starch, moisture, ash, and color were analyzed to assess porang flour quality. The results showed that pH decreased and total acidity increased with the length of fermentation up to 72 hours. Yeast increased at 10% and 20% S. cerevisiae concentrations until 48 hours and decreased at 72 hours, whereas in the control treatment, population of yeast decreased up to 48 hours and increased at 72 hours. The study indicated that fermentation with S. cerevisiae effectively reduced calcium oxalate content and improved porang flour quality. The lowest calcium oxalate content was found in the 10% S. cerevisiae treatment, while the highest glucomannan content was observed in the 20% treatment. Porang flour treated with 20% S. cerevisiae showed lower moisture and ash content, while flour from the 10% treatment had higher starch content and a brighter color. Based on various test parameters, the porang flour produced in this study complied good quality standards.
