<![CDATA[This research aims to determine metal pollution in the Marbau river basin in North Labuhanbatu Regency. Sampling was carried out at 3 monitoring points in the upstream to downstream areas of the Marbau River in North Labuhanbatu Regency. Determination of sample return points. The method used is purposive sampling, by determining sampling points based on the differences in characteristics found in the research area. Some of the parameters measured are temperature, conductivity, turbidity, total dissolved density, BOD, COD, DO, pH, nitrate and chlorophyll which are then compared with the Standard Criteria for Class III river water quality according to the attachment to the reference regulation PerMenKes No.32 of 2017. The research results show that the upstream to downstream areas of the Marbau River are areas that can be categorized as low level pollution referring to PP RI NO 82 TAHUN 2001 with the specified quality standard for the heavy metal lead being 0.003 ppm. The conclusion of the analysis of the heavy metal lead (PB) from upstream to downstream of the Marbau River shows that the heavy metal lead (PB) pollution in the river is still relatively low or has not been contaminated by the heavy metal lead (PB). Keywords: Labuhanbatu, Marbau, Water Pollution]]>

<![CDATA[This study aims to explore the benefits of bajakah (Spatholobus littoralis Hassk) through the study of its utilization as a hepatoprotector. This research method is quantitative. Bajakah stem extract was made using 96% ethanol solvent using the maceration method. Analysis was carried out using liver histology preparations to determine the HAI (Histology Activity Index) Knodel Score. The treatment group consisted of 5 groups, namely, a) negative control (K1) treated with toxic doses of CCL4; b) positive control, namely vitamin E 46.8 mg/KgBW; c) P1 (treatment 1) was 750 mg/KgBW of Bajakah stem extract; d) P2 (treatment two) was 1200 mg/KgBW of pirated stem extract; e) P3 (treatment of three) was extract of the stem of Bajakah 1500 mg/KgBB. The results showed that the post hoc LSD test results in the P1 group had a histopathological picture of damaged liver, there was a significant difference with the K and P3 groups (p <0.05), but there was no significant difference when compared with the P2 group. Meanwhile, the P3 group had significant differences when compared to all groups (p <0.05). In conclusion, the administration of extract of pirated stems at a dose of 1,500 mg/Kg has a significant effect on the HAI value on the average number of hepatocytes with parenchymatous degeneration and necrosis after CCL4 induced Keywords: Bajakah, CCL4, Hepatoprotective]]>

<![CDATA[This research aims to determine the compressive strength of paving blocks produced from plastic waste through a comparison with paving blocks made from a mixture of plastic and sand, as well as factory-produced paving blocks used for the UIN Fatmawati Sukarno Bengkulu campus courtyard. The research is conducted using an experimental method, starting with the manufacturing of plastic-based paving blocks and followed by strength testing in the civil engineering laboratory of the University of Bengkulu. The results of the research show that the compressive strength of factory-produced paving blocks made from sand and cement averages 5.9 MPa, while the compressive strength of paving blocks made from a mixture of plastic and sand averages 1.32 MPa, and the average compressive strength of paving blocks is 2.23 MPa. In conclusion, the compressive strength of paving blocks made from pure plastic or a mixture of plastic and sand is still below the SNI 03-0691-1996 standard due to the brittle nature of plastic. Keywords: Conversion, Plastic, Paving Block]]>

<![CDATA[This study aims to isolate cellulolytic bacteria that have the potential to degrade cellulose by taking home-scale diaper waste samples. This research was also conducted to isolate and determine the ability of bacteria to degrade cellulose based on the Congo red test and filter paper degradation test. This research method is descriptive qualitative. Isolation of cellulolytic bacteria was carried out using selective Carboxymethyl Cellulose (CMC) media. The characterization was carried out by growing selected pure isolates on CMC media and then dropping congored drops to test their cellulolytic potential (cellulolytic potential is indicated by the appearance of a clear zone around the colony). The results showed that the results of isolating bacteria obtained 12 isolates that were able to grow and utilize cellulose as a carbon source. In the Congo red test isolate DS07 cellulolytic bacteria of the Hafnia genus had the highest cellulolytic index value of 2.5 mm. Isolate DS03 with the genus Bacillus had the highest ability to degrade cellulose on the Whatman No. filter paper test. 1 of 16.66%. Keywords: Bacteria, Diapers, Isolation, Cellulolytic]]>

<![CDATA[This research aims to determine the antioxidant activity of ciplukan leaf kombucha on variations in sugar type and fermentation time and to determine the organoleptic quality of ciplukan leaf kombucha on variations in sugar type and fermentation time. The research method used was descriptive quantitative and qualitative using experimental methods and a Completely Randomized Design with 2 factors with 3 replications. The results of the research showed that the antioxidant activity of ciplukan leaf kombucha was highest in the G1F2 treatment (225 grams of ciplukan leaf kombucha with palm sugar and 7 days of fermentation), namely 47.4%. Meanwhile, the highest organoleptic quality of ciplukan leaf kombucha in the G1F2 treatment (225 gram palm sugar ciplukan leaf kombucha and fermentation time of 7 days) was that it had a pleasant taste, sour taste, had a typical kombucha aroma and was brown in color. In conclusion, the type of sugar has no significant effect on the antioxidant activity of ciplukan leaf kombucha and the fermentation time has a significant effect on the antioxidant activity of ciplukan leaf kombucha.

<![CDATA[This study aims to determine the effect of colchicine on the stomata of dendrobium orchids. This research method is quantitative. This research used 2 factorial RAK where the first factor was the variety treatment consisting of dendrobium venus purple algis (ALG) and dendrobium transient pink frederika (FRD). The second factor, namely the colchicine concentration treatment, consisted of control (0 ppm), 4000 ppm, 5000 ppm and 6000 ppm. The research parameters observed were stomata density, stomata length and width. The results showed that dendrobium orchid varieties FRD and ALG were treated with several concentrations of colchicine with the average parameters of open stomata, stomata density, length and width of somata not significantly different from each treatment or control. Colchicine still does not appear to have an effect on the stomata of the FRD and ALG varieties of dendrobium orchids. Based on observations of the stomata, the average length of the stomata at each concentration is still not classified as diploid because it is <1.25x the length of the control stomata. In conclusion, the observed parameters have no effect or are significantly different. Keywords: Dendrobium Orchid, Colchicine, Stomata]]>
