  • Antibacterial Activity of Melaleuca alternifolia Extract From Different
           Extraction Method

    • Authors: Yuli Widiyastuti, Husnul Khotimah Matoha, Fitriana Fitriana
      Abstract: Antimicrobial resistance is an important issue that should be overcome globally. Melaleuca alternifolia is a powerful antimicrobial agent that could be one of the solutions to antimicrobial resistance with its wide range of antimicrobial activity. Steam distillation is used to utilize this plant to produce tea tree oil (TTO). This process has several drawbacks and studies have stated toxicity and adverse effects associated with oral administration of TTO. The usage of other extraction methods for M. alternifolia is not extensively studied.  The bioactive compound and antibacterial activity of M. alternifolia obtained from conventional extraction methods (maceration, soxhletation, and hydrodistillation) was studied to allow better utilization of this plant. Compounds present within each extract were observed using thin-layer chromatography (TLC),  the antibacterial activity of the extracts was evaluated using the Kirby Bauer method against Staphylococcus aureus and Escherichia coli, whereas the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was determined by broth dilution method. Analysis of compounds observed in TLC suggests that cardiac glycosides and terpenoids could be present in maceration and soxhlet extracts. This study suggests that maceration and soxhletation yielded different bioactive compounds from  M. alternifolia. Extracts of M. alternifolia from maceration and soxhelatin method have an excellent activity to inhibit the S. aureus, and E. coli in a dose-dependent manner. Maceration extract of M. alternifolia has a stronger effect against E. coli meanwhile the soxhelation extract of M. alternifolia reveals to have stronger antimicrobial activity against S. aureus. The same MIC and MBC values for all extracts (Maceration = 0.1875%; Soxhletation = 0.1875%) were observed from E. coli. MBC of S. aureus is two to more than fourfold of the MIC, with maceration having the highest MBC (MBC = >12%). Moreover, these extract also possess similar antibacterial activity to those observed in the tea tree oil.

  • The Effect of Ciplukan (Physalis minima) Leaf Extract on Mesenchymal Stem
           Cell Proliferation and Population Doubling Time (PDT) In Vitro

    • Authors: Kartini Eriani, Irma Suryani, Suhartono Suhartono
      Abstract: Ciplukan(Physalis minima) has been used as herbal medicine because it is believed by the community to cure neurodegenerative and cardiovascular diseases. This study aims to determine the effectiveness of P.minima extract in increasing the proliferation of mesenchymal stem cells (MSC) from mouse (Mus musculus) bone marrow (BM). Bone marrow from the femur and tibia were isolated using a flushing method. BM-MSC primary culture was conducted in mesenPROÒ medium at 37ᵒC in a 5% CO2 incubator until it reached a 70% confluence.BM-MSCs were sub-cultured overnight in Dulbecco's Modified Eagle's Media (mDMEM). The mDMEM was replaced with a treatment medium on the second day of subculture. The treatment medium was changed every three days and evaluated under an inverted microscope by counting the number of cells at the beginning and the end of the incubation period. The proliferation rate is expressed as Population Doubling Time (PDT), which was statistically analyzed using ANOVA at a significance level of 0.05% and followed-up with Duncan's test. The result demonstrates that induction of P. minima leaf extract effectively increased the number of BM-MSC cells. Statistically, P. minima leaf extract could significantly reduce the PDT value. The optimum dose of P. minima leaf extract that can increase the proliferation of BM-MSC was 0.8 mg/ml. It is concluded that P. minima leaf extract was effective as an inducer of BM-MSC proliferation. The result of this studyis preliminary data on the use of extracts in stem cell-based therapy for degenerative diseases.

  • Callus Development from Potato (Solanum tuberosum) Stem at Various
           Concentrations of Benzylaminopurine

    • Authors: Megananda Aprilia, Nintya Setiari, Yulita Nurchayati
      Abstract: Potato has the potential for food diversification.The propagation method in a short period is needed. One of the methods used is plant tissue culture. Benzyl Amino Purine (BAP), determine the success of propagation by tissue culture method. This research aimed to study the use of different BAP concentrations for callus development from stem explants. The explants put on culture medium added by 0, 1, 2, 3 ppm BAP. The development of the stem explant observed every week for a month. The results showed that callus formed in all media. Without BAP treatment, callus were formed after 2 weeks and got browning, then stopped growing. Callus grew and showed differentiation by application of all the BAP concentration. Callus greowth was optimally at 2 ppm BAP treatment. The callus from 1 ppm BAP produced the most number of roots, shoots and leaves than another concentration.  This experiment showed that different BAP concentrations affected callus development of S. tuberosum from stem explant. The conclusion was callus growth has obtained by the treatment of 2 ppm BAP, while the development of callus has obtained on addition of 1 ppm BAP. The novelty of this research is the callus induction method from potato sprout stems grown from potato seeds with plant growth regulators Benzyl Amino Purine. Callus induction method from potato sprout stems grown from potato seeds can be a guide for embryogenic callus induction.

  • Mechanical Scarification Influence on Gleditsia assamica Bor Water Uptake
           and Germination

    • Authors: Farid Kuswantoro, Arrohmatus Syafaqoh Li’aini
      Abstract: Physical dormancy is a typical kind of dormancy in Fabaceae species, including Gleditsia assamica. Physical dormancy is caused by the impermeability of the seed coat and can be alleviated, among others, by mechanical scarification. Previous studies on mechanical scarification effect on G. assamica seed focus only on its germination parameter without regard to its effect on seed water upatke. As germination is initiated with water uptake, current study aims to understand the treatment effect on both of seed water uptake and germination parameters. Tetrazolium dyeing and seed weight measurement trials were conducted to study the seed water uptake. Meanwhile, a germination test is conducted to investigate the treatment's influence on the seed germination parameters. This study shows that mechanical scarification can enhance G. assamica seed water uptake. The treatment was also significantly improve final germination percentage and germination speed index. This study result gives us a clearer understanding of the effect of mechanical scarification to alleviate G. assamica dormancy and germination, which will be advantageous to the species conservation and domestication efforts.

  • DNA Barcode of Red Junglefowl Gallus gallus L, 1958 (Aves: Phasianidae) of
           Sumatra Based on Mitochondrial COI DNA Gene

    • Authors: Jarulis Jarulis Jarulis, NURMEILIASARI NURMEILIASARI, HERY HARYANTO, IQWATI VILANDA
      Abstract: Genetic data of red junglefowl (Gallus gallus) from southern Sumatra is valuable for conservation efforts in Indonesia. A mitochondrial COI DNA gene sequencing was performed to elucidate its genetic character, single nucleotide polymorphism, genetic distance, and phylogeny. Blood samples (±0.5 ml) from 20 individuals of Gallus gallus were taken from the living collections of the people of Bengkulu Province (Central Bengkulu Regency and Seluma Regency) and South Sumatra Province (North Musi Rawas Regency) from May to November 2021. Total DNA isolation followed the procedure of The Spin-Column Protocol Kit uses the Dneasy® Blood and Tissue Kit, Qiagen. DNA replication using the Polymerase Chain Reaction technique with primers (COIGG_F and COIGG_R) using MEGA 10.0 software and Bioedit for data analysis. The results revealed716 conserved sites, 16 variable sites, 9 parsimony sites, and 6 singleton sites from the 732 bp nucleotide sequence. Six specific sites (SNPs) as barcodes for Sumatran Junglefowl were found at sequences 51, 273, 327, 721, 729, and 732. The mean genetic distance between individuals was 0.1%, between populations was 0.8%, between species was 7.4%, and between genera was 15.5%. The red junglefowlof South Sumatra Province and Bengkulu Province are closely related with 98% bootstrapping and separated from other Gallus in the same group (ingroup) with 100% bootstrap. The Gallus-gallus group is quite far apart from the outgroup species in the Phasianidae family with 47-100% bootstrap. Red junglefowl from southern Sumatra has genetic differences from other chickens in the world and these differences can be used as a species barcode and as origin identification the widely traded red jungle fowl.

    • Authors: Wulan - Christijanti, Aditya - Marianti, R. - Susanti, Senda Kartika Rakainsa
      Abstract: Hyperglycemia is one of the characteristics of diabetes mellitus that marks blood glucose levels higher than > 200 mg / dl. The management of diabetics includes treatment, diet, behavior, regular exercise and stress management. Many kinds of medicinal plants are used to maintain the stability of glucose levels. Moringa (Moringa oleifera) leaves are known to have various bioactive components that exhibit antihyperglycemic effect. The aim of the study was to analyze the role of moringa leaf extract to the liver function parameters of hyperglycemia rats. There were 4 groups, normal control (K0), aloxan-induced hyperglycemia (125 mg/kg body weight) that were divided into three groups with moringa leaf extract treatment doses of 0 mg (K1), 200 mg (T1) and 400 mg/kg body weight (T2) for 21 days. Variables measured levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The data was analyzed with Anava P<0.05 and Least Significance Different (LSD) test.  The results showed that the highest levels of AST dan ALT in the K1 group were then significantly decreased in the group that obtained moringa extracts (T1 and T2). There was significant difference between groups including control and treatment groups (p<0.05). The result of the research showed that moringa leaf extract has an effect on lowering the levels of liver enzymes in hyperglycemia rats

  • Properties of Bio-Silver Nanoparticles Mediated by Tuber and Leaf Extracts
           of Manihot esculenta Crantz

    • Authors: Synodalia C. Wattimena, Desy A. Ayuningrum, Leonita Y. Latuasan, Efraim Samson, Philipus J. Patty
      Abstract: Bio-silver nanoparticle using plant extract has been the subject of many studies nowadays. Researchers use various plant extracts, especially the popular plant from their places. This study aims to synthesize AgNPs using leaf and tuber extracts of Manihot esculenta and to characterize their properties to be compared one to another. The characterization includes surface plasmon resonance wavelength using UV-VIS spectroscopy, the chemical bonds related to the extract on the surface of the particles using FTIR spectroscopy, shape and size of the particles using TEM, and antibacterial properties using the disc diffusion method. Each tuber and leaf extract AgNPs were formed a few minutes after mixing silver nitrate with each extract indicated by the change of the color from transparent to yellowish-brown. The color of the sample was quantified by the wavelength of surface plasmon resonance which was found to be 425 nm for tuber extract AgNPs and 430 nm for leaf extract AgNPs. The results of FTIR spectroscopy indicate the presence of the extract at the surface of nanoparticles for both samples. The particles are mostly spherical, but the diameters of the leaf extract AgNPs are relatively smaller than those of the tuber extract AgNPs. The results of antibacterial assays of both samples show that both AgNPs inhibit the growth of S. aureus as effectively as they inhibit the growth of E. coli.

  • Inulinase Producing Yeast Isolated from Kepok Banana Peels (Musa acuminata
           x balbisiana)

    • Authors: Romario Dion, Wijanarka Wijanarka, Sri Pujiyanto
      Abstract: Inulinase enzyme (EC 3.2.1.80) is an enzyme capable of hydrolyzing inulin and is used as a catalyst in the production of High Fructose Syrup (HFS) and fructooligosaccharides (FOS). Inulinase enzymes can be produced by yeasts found in waste such as kepok banana peels (Musa acuminata x balbisiana). The aims of this study were to obtain the inulinase enzyme-producing yeast from kepok banana peels and to determine the effect of commercial inulin concentration and incubation time on enzyme activity. This research was conducted experimentally using a factorial completely randomized design with factors being inulin concentration of 1% (K1), 3% (K2) and 5% (K3) and incubation time of 6th (W1), 12th (W2), 18th (W3), and 24th hours (W4). The results showed that there were 4 isolates of inulinolytic yeasts obtained from kepok banana peels, namely YP1, YP2, YP4, and YP6. However, the most potential isolate to be used in inulinase production was YP2 isolate because it had the highest inulinolytic ratio value of 1.96. The results of inulinase activity showed that only inulin substrate with concentration of 5% (K3) had a significant or significant effect on inulinase production.

    • Authors: Sunarno Sunarno, Rully Rahadian, Sri Widodo Agung Suedy, Fendi E. Wahyudi, Ardi Sugianto, Bima Adistya, Afiarta Akbar Alfiyansyah
      Abstract: Flora biodiversity has been known to have a vital function in reducing carbon emissions in the air and contributing oxygen in significant levels to the environment. PT. Pertamina (Persero) Fuel Terminal Boyolali (FTB) has an important role in the conservation programs, protection of flora biodiversity, and environmental management. This study aims to analyze carbon stocks found in trees, plants cover soil, litter, necromas, and carbon in the soil and evaluate conservation of flora. This study uses a purposive random sampling method of carbon sources followed by the determination of carbon stocks in three conservation areas managed by PT. FTB, namely in the Wonopotro Forest, in the Pepe River watershed, and Pertamina's operational area. The samples from carbon sources include trees, litter, ground cover plants, necromas, and soil. The trees and necromas carbon sources sampling at each location was carried out at 2 stations with a size of 10 x 50 m2. Meanwhile, the sampling of litter, ground cover plants, and soil was carried out at 2 stations, each consisting of 3 plots. The results showed that the total carbon stock in the conservation areas was 1,688,0791 tons. The Pepe River watershed has the highest total carbon stock, which was 1,466,0928 tons/ha. The FTB and Wonopotro Forest, respectively, have about 180.7569 and 41.2294 tons/ha. The novelty of this research is the method of calculating carbon stocks in a conservation area that can be used as a database for assessing environmental management performance to the preservation of biological resources.

  • Waste and Water Management Practices and Environmental Attitudes of the
           Riparian Communities in Sapangdaku River in Toledo City, Cebu, Philippines
           

    • Authors: Joje Mar Perino Sanchez
      Abstract: This study examined the water utilization, waste disposal practices, and environmental attitudes of the riverside dwellers in a Philippine rural municipality. It also looked into the possible health impact of such practices on the community. The municipality river being the water source and provider of various domestic functions had played important socio-cultural value. As the degree of pollution and deterioration of water quality kept on worsening, the empirical study must be conducted for water monitoring and community household engagement to ensure sustainable use of a healthy river system. Socio-health and environmental attitudes surveys were randomly given to 120 residents across downstream, midstream, and upstream sites of the municipal river. Data on attitudes were subjected to the Pearson r correlation at α=0.05. Around 34% of the residents had experience being concerned with the river, while about 25% continue to use it. Waste disposal, animal bathing, and water drinking have since decreased, while quarrying activity kept increasing since. The residents usually use district water for bathing, cooking, flushing, and laundry while distilled/purified/mineral water for drinking. Moreover, indiscriminate disposal of both solid and liquid waste remained highly practiced and reported. Cough, flu, diarrhea, and skin ailments are the common diseases experienced by the riparian inhabitants. Their ecocentric concern is moderately positive and significantly correlated to their environmental movement activism as manifested in their strong opposition to solid and human waste disposal and quarrying/mining activities. There is a probable link to the health issues and the utilization and current river condition of the river. Developing positive attitudes translates to the positive actions of the riverside dwellers. The implications of this study can enhance public awareness of the importance of preservation and restoration of rivers. Local government units can implement an initiative for stringent monitoring, mitigation, and remediation of the river.

  • Electroencephalogram Detection for Insomnia Patients: A Preliminary Study

    • Authors: Inosensia Lionetta Pricillia, Ahmad Azhari
      Abstract: Insomnia is a disorder that causes sufferers to have difficulty sleeping or have less sleep than their portion. This insomnia occurs due to anxiety, stress, depression, bipolar disorder or trauma. Measurement of insomnia at this time is generally carried out by medical experts who are carried out by looking at the condition of the patient with symptoms that refer to insomnia, then it will then be diagnosed that the patient has a sleep disorder in the form of insomnia. At this time quantitative measurements are still very minimal found related to this insomnia. There is an alternative to scale measurements using an Electroencephalogram (EEG) using photic stimulation. By using the EEG tool, we can measure and record the activity of brain wave signals caused by the activity of neurons in the human brain. This study aims to be used as another alternative in identifying sleep disorders in the form of insomnia quantitatively. To get an analysis of the diagnosis of insomnia is to use EEG measurements with the use of a stimulus in the form of photic stimulation as listed above. The object of research involved in this study were late adolescents who had an age range of 17-25 years, who experienced symptoms of insomnia, who had previously been given tests related to sleep disorder treatment and identified severe, moderate and mild insomnia. Tests are devoted to Beta signals that will display conditions of focus, thinking, and concentration. EEG signal recording was performed using a Neurosky Mindwave Mobile 2 device with electrode placement in the Fp1 position. The Fp1 position that is meant here is by placing the electrode on the head with the sensor on the forehead. The expected result is to get a brain wave pattern, especially in beta signals for people with insomnia sleep disorders with an EEG measurement tool using a stimulus in the form of photic stimulationInsomnia is a disorder that causes sufferers to have difficulty sleeping or have less sleep than their portion.

  • Liver Histopathology of Rats Induced by High-Fat Feed After Giving Neem
           Leaf Ethanol Extract

    • Authors: Sri Isdadiyanto
      Abstract: Foods that contain high levels of fat can cause hyperlipidemia, which is one of the triggering factors for non-alcoholic fatty liver disease. Neem leaves contain flavonoids, alkaloids and tannins which have the ability to act as hepatoprotectors. This study aimed to determine the Liver Histopathology of Rats Induced by High-Fat Feed After Giving Neem Leaf Ethanol Extract. Twenty-four the male white rats (Rattus norvegicus L.) were divided into 6 treatment groups, namely: normal control (P0); negative control (P1: given high-fat diet); P2 treatment (P1+ 8 mg/200gBW simvastatin); and P1+ the dose of neem leaf ethanolic extract of  75; 100; and 125 mg/200gBW (P3; P4; and P5). Fixation process with 10% Neutral Formalin Buffer (NFB) solution. Liver histopathological preparations were made by paraffin method and Hematoxylin-Eosin staining, histopathological observations with a 400x magnification microscope. Liver histopathology was analyzed descriptively, homogeneous and normally distributed data of liver weight and hepatocyte diameter were analyzed statistically using ANOVA followed by Duncan's test with a significance level of 5% using SPSS 16.0 software. The results showed that the administration of ethanolic extract of neem leaves could improve the liver histology structure. From this study it was concluded that the ethanolic extract of neem leaves can be used as an alternative hepatoprotector.

  • APPLICATION OF UNMANNED AERIAL VEHICLE (UAV) REMOTE SENSING TECHNOLOGY FOR
           ESTIMATION OF TREE HEIGHT IN HETEROGENEOUS FOREST

    • Authors: Francine Hematang, Agustinus Murdjoko, Hendri Hendri, Max Tokede
      Abstract: Tree height is an important piece of information in forest management. Cost, time, and effort are some of the limiting factors in extracting tree height values on a large scale. The canopy height model approach through aerial photography using UAV can be used to quickly estimate the height of large-scale trees combined with field measurements. CHM analysis was carried out using spatial statistics to get the maximum tree height value based on the tree canopy. Evaluation of accuracy in the form of statistical tests is used to assess the level of accuracy of the estimation. Photogrammetry results show that the obtained CHM has a resolution of 11.8 cm/pixel with the results of the evaluation of tree height accuracy having an RMSE of 2.4 m, MAE 2.0 m, SDE 3.8 m. The chi-square statistical test shows that the results of the tree height estimation accept H0 and there is a strong relationship between the observed tree height and the estimation through linear regression with an R2 value of 0.67. The broad estimation of height shows that Mansinam Island has a tree height in the range of 7 – 66 m. The dominant tree height is in the 19-30 m class with the number of individuals reaching 1,877 trees. This study shows that CHM obtained from aerial photography using low-cost UAVs is still able to estimate tree height well. For future studies, it is necessary to use a ground control point (GCP) to increase the accuracy of the elevation model and orthophoto.
