Abstract

Kegiatan ini merupakan bagian dari program pengabdian kepada masyarakat yang bertujuan untuk meningkatkan kapasitas UKM Bank Sampah Mandiri di Kota Batam, khususnya dalam penyusunan laporan keuangan dan strategi pemasaran berbasis eCommerce. UKM ini bergerak di bidang pengelolaan sampah sebagai upaya untuk mengurangi dampak lingkungan. Namun dalam praktiknya, UKM ini menghadapi kendala dalam manajemen keuangan dan pemasaran produk secara efektif. Melalui program ini, dilakukan pelatihan dan pendampingan secara tatap muka dan daring guna memberikan pemahaman kepada pelaku UKM mengenai penyusunan laporan keuangan yang lebih sistematis dan terstruktur. Selain itu, pelatihan juga mencakup pengenalan strategi pemasaran digital melalui platform eCommerce sebagai alternatif promosi dan penjualan. Hasil kegiatan menunjukkan bahwa peserta mengalami peningkatan dalam kemampuan menyusun laporan keuangan serta memahami pentingnya pemanfaatan teknologi digital untuk mendukung pemasaran. UKM mulai menerapkan eCommerce untuk menjangkau pasar yang lebih luas dan meningkatkan efisiensi operasionalnya. Program ini tidak hanya memberikan dampak positif bagi UKM yang menjadi mitra, tetapi juga berpotensi menjadi model pembinaan bagi UMKM lain yang menghadapi tantangan serupa. Lebih jauh, kegiatan ini turut mendorong penguatan kapasitas masyarakat lokal dalam penguasaan teknologi dan kewirausahaan, sehingga dapat berkontribusi pada pembangunan ekonomi masyarakat berbasis digital secara berkelanjutan.

Abstract

The current interest in exploring white-rot fungi has been concentrated in increasing their ligninolityc enzyme production such as laccase and manganese peroxidase (MnP) due to the great value in industrial application. The presence of appropiate inducers can enhance the enzyme production. Hence, the aim of the study was to investigate the activity of laccase and MnP in response to various aromatic compounds. The fungus Trametes hirsuta was cultured in Glucose Yeast Peptone (GYP) broth (pH 5.0) with the addition of 0.5% of sorghum biomass as substrate. The cultures were then incubated on rotary shaker at 150 rpm at 27oC. The 7-day-old cultures were then supplemented with different aromatic compounds, namely caffeic acid, gallic acid, syringic acid, trans-cinnamic acid, vanillin, and veratryl alcohol. Our results demonstrated that veratryl alcohol, gallic acid and vanillin gave an inductive effect on the value of laccase and MnP activities, with vanillin showing the highest induction. On the contrary, the level of laccase and MnP activities remained low in the presence of aromatic compound such as syringic acid, trans-cinnamic acid and caffeic acid. To conclude, our study reveals that aromatic compounds can be potential as inducers and may contribute to the improvement of laccase and MnP productivity by T. hirsuta.

Abstract

Lactic acid bacteria (LAB) are important for prevention of spoilage and pathogenic bacterial growth in foods due to their ability to generate antimicrobial substances. The objective of this study was to screen LAB for antimicrobial activity and to optimize culture medium for antimicrobial production using Response Surface Methodology (RSM) with Central Composite Design (CCD). Optimization of antimicrobial production of selected LAB was conducted with different combinations of glucose, NaCl, inoculum, and temperature. Our experimental results showed that from 129 LAB isolates, 55 showed significant inhibition against Bacillus subtilis, Escherichia coli, Micrococcus luteus, Staphylococcus aureus, Aspergillus niger, and Candida albicans. No isolates inhibited the growth of Aspergillus flavus. Lactobacillus plantarum LIPI13-2-LAB011 was selected for further study on culture medium optimization to inhibit the growth of C. albicans. From statistical analysis, the production of antimicrobial substances was significantly influenced by temperature, NaCl, and concentration of glucose. Furthermore, the optimum concentrations of glucose, concentration of inoculum, temperature, and NaCl were 1.63 %, 3.03%, 33.74°C, and 3.4%, respectively, with a maximum predicted inhibition index of 1.916, which increased 3.56-fold compared to that obtained in medium before optimization processes. The result was confirmed as when the optimum concentration of nutritions used, the inhibition index increased 3.12-fold.

Abstract

Alkanes are major component of crude oil that could be hydrolyzed by the enzyme of alkane hydroxylase. The are three types of alkane hydroxylase based on the chain length of alkane such as short-chain length/SCL (C2-C4), medium-chain length/MCL (C5-C17), and long-chain length/LCL (C>18). The aims of this study were to characterize and identify alkanes-degrading bacteria from these bacteria. The 30 strains from marine were grown on MCL (Pentane-C5H12, Decane-C10H22, and Pentadecane-C15H32) and LCL (n-Paraffin-C12H19C17 and branch of Pristane-C19H40). The study showed twenty-nine isolates have the ability to degrade alkanes compounds, whereas 14 isolates have grown ability on MCL and LCL medium, 11 isolates have the ability to grow on MCL and n-LCL, 3 isolates have the ability only to grow on MCL medium and 1 isolate has the ability only grow on n-LCL medium. The growth test result indicated that 29 isolates have medium-chain alkane monooxygenase and long-chain alkane hydroxylase. Based on 16S rDNA gene analysis, we obtained twenty nine of oil- degrading bacteria, namely a-proteobacteria (57 %), g-proteobacteria (30 %), Flavobacteria (7 %), Bacilli (3%) and Propionibacteriales (3 %). g-Proteobacteria and a-proteobacteria which seems to play an important role in the alkane biodegradation.

Abstract

Dibenzothiophene (DBT) and its derivatives have been widely used as model organic sulfur compounds in petroleum, included their biodegradation process. The abilities of microorganisms to degrade pollutants are significantly influenced by various factors such as microbial species, nutrients and environmental parameters. In this research, we carried out further study to determine optimal condition for DBT biodegradation regarding with substrate and strains cell concentration by several indigenous marine bacteria from Indonesia. These three isolates were belong to Mauricauda olearia, Alcanivorax xenomutants, and Stakelama pacifica, with homology result 99% each. Optimal dibenzothiophene as substrate reached by all isolates is 100 ppm, while cell concentration or microbial numbers that gave highest growth for all isolates is 20 based on conversion of OD600 nm measurement.

Abstract

Polycyclic Aromatic Hydrocarbons (PAHs) as well as crude oil are widespread environmental pollutants. The contamination of air, soil, freshwater (surface water and groundwater), and marine environments by PAHs as well as crude oil has been reported. Of concern to public health is the fact that many PAHs or their metabolites are mutagenic, carcinogenic, or both. North Java coastal area such as Jakarta Bay is the polluted marine area in Indonesia as a result from anthropogenic wastes and the oil spill. Although evaporation and photo-oxidation play an important role in oil detoxification, ultimate and complete degradation is accomplished mainly by marine micro flora, and being dominant in this function. Certain bacteria are well-known could consume and degrade the PAHs as well as crude oil. Therefore investigating the potential PAH and oil degrading marine bacteria is important. In this study, we collected sample from oil polluted area in Marina Port Ancol, Jakarta Bay and isolated four PAH substrates and Arabian crude oil degrading marine bacteria using enrichment method and direct isolation method. As result, 223 strains could degrade PAHs, among these strains, 94 strains could degrade phenanthrene, 23 strains degrade fluoranthene, 92 strains could degrade dibenzotiophen, 14 strains could degrade phenotiazin and 106 isolates degrade crude oil.
