Abstract

Porong River is an active river located in the Sidoarjo region, East Java which has been polluted by the Lapindo mudflow containing various chemical compounds, one of which is lead (Pb) heavy metal. Isolation of bacteria in the environment contaminated with Pb allows bacteria that have the potential as bioremediation agents to grow. The purpose of this study was to determine the content of heavy metal Pb and isolate and identify lead (Pb) tolerant bacteria in water and sediment at Porong river, Sidoarjo. Sampling of water and sediment was carried out at 2 sampling points based on the presence of Lapindo mud waste flow. Analysis of the heavy metal content of Pb was carried out using the Atomic Absorption Spectrophotometer (AAS). Bacterial isolation was carried out on NA media containing 10 ppm Pb of heavy metal and incubated for 24 hours at 300C. Bacterial isolates were identified based on the macroscopic and microscopic properties and biochemical tests. The results of the heavy metal content of Pb at sampling point 1 in water was 0.81 ppm, and in sediment was 0.98 ppm while at sampling point 2 in water was 2.93 ppm, and in sediment was 3.88 ppm. The results of bacterial identification obtained as many as 6 bacterial isolates belonging to 3 genera of bacteria including Bacillus, Acinetobacter and Pseudomonas.

Abstract

SCOBY (Symbiotic Culture of Bacteria and Yeast) results from symbiosis between yeast and bacteria during fermentation. SCOBY kombucha gel combined with orange peel extract has antibacterial compounds that can inhibit the growth of S. aureus bacteria. The method in this study was to make variations in the concentration of SCOBY in the gel and inject S. aureus bacteria into the ears of mice. After 2x24 hours, the diameter of the inflammation caused was observed and SCOBY kombucha gel was applied (0%, 2%, 4%, 8%, 10%, and 12%), positive control (Mediclin 1%), and negative control (without gel application). The results showed that the higher the concentration of SCOBY, the faster the healing activity of the gel against S. aureus. SCOBY kombucha gel has the fastest healing activity in inhibiting acne pathogen S. aureus 12% SCOBY gel. Inflammation in the ears of mice treated with 12% SCOBY gel had healed by the 90th hour, while in other groups of mice it had only healed at the last observation hour, namely the 114th hour.

Abstract

Corn is a substitute food crop for rice, and its number continues to increase yearly. Therefore, corn has experienced an increase in productivity because many Indonesian people like corn. The supporting factor for a plant to develop well is the provision of fertilizer. The fertilizers used by Indonesian farmers are generally not environmentally friendly and damage soil nutrients, such as inorganic fertilizers or chemical fertilizers. Therefore, environmentally friendly fertilizers from living organisms are needed to increase nutrients with biological fertilizers (PGPR). The aim of this research is (1)to determine the effect of PGPR Bacillus sp. and Pseudomonas sp. from the roots of apus bamboo on the growth of corn plants, (2) knowing the comparison of variations in the concentration of PGPR Bacillus sp. and Pseudomonas sp. on corn growth. This research was carried out from January to February 2024 at the laboratory and the greenhouse of BBPPTP Surabaya. The research sample used was 21 corn plant seeds. The research variables used were plant height, root length, number of leaves, root fresh weight, leaf fresh weight, root dry weight, and leaf fresh weight. The research results were analyzed using the SPSS test (One-way ANOVA and DMRT) and presented in a table. The result showed that isolates of Bacillus sp. and Pseudomonas sp. had a natural effect on corn, while the best concentration was given at a Bacillus sp. concentration of 15% and Pseudomonas sp. 15%.

Abstract

Indonesia memiliki potensi sumber daya perikanan yang besar, salah satunya ikan kembung banyak dikonsumsi karena memiliki nilai gizi tinggi dengan harga terjangkau. Namun, pada aktivitas penangkapan dengan durasi lama dapat menyebabkan penurunan kualitas ikan akibat aktivitas enzim dan mikroorganisme pembusuk. Tanaman kemuning memiliki potensial dalam mencegah proses pembusukan ikan, hal ini karena memiliki kandungan antibakteri. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak daun kemuning sebagai bahan pengawet alami ikan kembung serta variasi larutan pengencer dengan air tawar dan air laut terhadap kualitas kimia berupa kadar air dan pH, serta nilai organoleptik. Penelitian ini terdiri dari 11 perlakuan, terdiri atas kontrol negatif (ikan kembung tanpa perendaman, ikan dengan direndam air tawar, air laut), kontrol positif (pengawet komersil), ekstrak daun kemuning konsentrasi 100% (tanpa pengencer), konsentrasi 30%, 50%, dan 70% (pengencer air tawar dan air laut). Data di analisis secara statistik menggunakan Kruskal Wallis. Hasil penelitian menunjukkan nilai kadar air seluruh perlakuan masih berada pada kisaran standar mutu ikan segar, yaitu 66,6%–70%, dengan kadar air terendah pada perlakuan K1AL yaitu 66,6%, sedangkan nilai pH masih memenuhi standar kesegaran ikan, berkisar 6,26–6,46 dengan kadar pH terendah pada perlakuan K1AT 6,26. Nilai organoleptik (kenampakan rupa, bau, tekstur) tertinggi diperoleh pada perlakuan K2AL dan K3AL dengan rata-rata sebesar 7,46. Perlakuan ekstrak daun kemuning dengan pengencer air laut lebih efektif sebagai pengawet alami dibandingkan pengencer air tawar.

Abstract

  Dimethomorph is a systemic fungicide utilized within Indonesian agricultural sector. Inappropriate application of dimethomorph fungicide may result in environmental contamination and the development of resistance among rhizosphere microorganisms. This study aims to ascertain the responses of rhizosphere microbial isolates to dimethomorph fungicide, thereby providing critical insights for evaluating the efficacy of this fungicide against rhizosphere microbes. Such information is essential for formulating plant pest and disease management strategies that utilize more suitable and sustainable dosages. The investigation involved testing bacterial isolates MR-B01, MR-B02, MR-B03, MR-B04, and fungal isolate MR-F01 against dimethomorph fungicide employing the agar diffusion method with disc paper. The experimental design incorporated a treatment factor with five variation concentrations of dimethomorph fungicide (0 g/L, 0.5 g/L, 1 g/L, 1.5 g/L, and 2 g/L), executed with ten repetitions. The findings indicated that varying concentrations of dimethomorph fungicide exhibited distinct effects on the resistance of the tested microbial isolates, specifically bacteria MR-B01, MR-B02, MR-B03, MR-B04, and fungal isolate MR-F01.
