Abstract

Mitra dalam pengabdian ini adalah masyarakat, namun terfokus pada edukasi berupa bimbingan belajar untuk siswa Sekolah Dasar di daerah Karang Anyar RT 05, Karang Anyar, Plupuh, Sragen. Metode pelaksanaan pengabdian ini diawali dengan mengadakan sosialisasi kepada orang tua siswa melalui kelompok kecil. untuk menyampaikan informasi mengenai adanya kegiatan bimbingan belajar. Selalin itu juga kami memberi gambaran mengenai konsep orangtua dalam mendampingi anak ketika pembelajaran daring. Dalam pelaksanaannya bimbingan belajar dilakukan setiap hari mulai jam 09.00-11.00 WIB. Diikuti oleh dua belas siswa, yang terdiri dari tujuh siswa laki-laki dan lima siswa perempuan. Bertepat di Masjid Baiturrahim. Proses belajar sebelum adanya “bimbingan belajar” terkesan monoton dan siswa kurang memahami materi karena tidak adanya tempat bertanya dan praktik. Namun dengan adanya bimbingan belajar yang memanfaatkan media audio visual ini siswa menjadi lebih mudah memahami materi dan kembali aktif bertanya tidak monoton dengan cara belajar sebelum mengikuti bimbingan belajar ini. Hal ini menunjukkan pentingnya pemberian pengalaman pada siswa pada saat proses pembelajaran. Pentingnya pengabdian ini dilaksanakan sebagai upaya membantu orang tua dalam mendampingi proses pembelajaran siswa dan sebagai fasilitator siswa dalam membantu siswa memahami materi.

Abstract

AbstractFive isolates of endophytic bacteria from the roots of klutuk and ambon banana plants produce indole acetic acid (IAA) hormone. However, the evidence of its potential as Plant Growth Promoting Bacteria (PGPB) has not been observed. Therefore, this study aims to determine the effect of bacterial isolate to increase the growth of rice and maize plants. The growth rates of bacterial isolates were measured before the inoculation into the plant root. The root inoculation was performed following a complete randomized design. Root inoculation was carried out using 5 isolates of endophytic bacteria in rice and maize plant seedlings, and the process was repeated 15 times (n=15). The growth of rice and maize plants was monitored from 1st day after planting (dap) to the 14th dap. The collected data were analyzed by student t-test with a significant level of 5% (a= 0.05). The results showed that the logarithmic phase of all isolates was reached at 4 to 16 hours and K10, K25, K35, K111, and A41 isolates increased the height of plants while the K111 isolate can significantly increase the plant height compared to the control. This experiment revealed that the endophytic bacteria from banana plants increase the rice and maize plant’s growth.AbstrakLima isolat bakteri menghasilkan hormon indole acetic acid (IAA) yang berpotensi memacu pertumbuhan tanaman. Namun, bukti empiris potensinya sebagai Plant Growth Promoter Bacteria (PGPB) belum didapatkan. Penelitian ini bertujuan untuk mengetahui pengaruh isolat bakteri terhadap peningkatan pertumbuhan padi dan jagung. Penelitian ini menggunakan metode eksperimen dengan desain rancangan acak lengkap dan setiap perlakuan diulang 15 kali (n= 15). Hasil pertumbuhan tanaman yang diinokulasi dengan isolat bakteri masing-masing dibandingkan dengan perlakuan kontrol. Sebelum perlakuan, tingkat pertumbuhan bakteri endofit diukur sehingga didapatkan fase logaritmik yang cocok untuk dilakukan inokulasi ke akar tanaman. Setelah perlakuan, pertumbuhan tanaman padi dan jagung dipantau dari hari ke-1 setelah tanam (hat) sampai dengan ke-14 hat. Data dianalisis dengan uji t dengan taraf signifikan 5% (α= 0,05). Hasil penelitian menunjukkan bahwa 5 isolat yang berasal dari tanaman pisang mengalami fase logaritmik pada masa inkubasi 4 hingga 16 jam dan semua isolat bakteri meningkatkan tinggi tanaman serta isolat K111 dapat meningkatkan tinggi tanaman secara signifikan dibandingkan dengan kontrol.

Abstract

Four endophytic bacteria have been isolated from banana kluthuk plants and banana ambon. Previous study showed that they produce Indole Acetic Acid (IAA). This study aimed to analyze the effect of endophytic bacterial inoculation on plant height and the number of rice root. For this reason, two endophytic bacteria of each klutuk banana and ambon banana plants were cultured and examined for growth rate using a 600 nm spectrophotometer. Isolate growth was calculated every two hours for 16 hours of bacterial growth in NB media. Bacterial inoculation experiments on rice plants were carried out with five replications. This inoculation begun with germination of rice seeds until the radicle was observed. Then germinated rice seedlings were soaked in a bacterial suspension for 1 hour at room temperature. The results showed the exponential phase of all isolates was observed at 6 hours with shaking. Inoculation using A22 and A51 isolates significantly increases plant height, number of leaves. While, A22 isolate significantly increased the number of roots compared to the uninoculated plants (control). It supports the potential of endophytic bacteria from banana kluthuk and ambon plants.

Abstract

Frangipani trees (Plumeria acuminata) are commonly found in cemeteries. Cemeteries are used as a location for interment so that the corpse actively decomposes to provide soil minerals that encourage the formation of microbes, including bacteria. Bacteria around the roots of frangipani trees are thought to have potential as plant growth-promoting rhizobacteria (PGPR). Based on reference searches, there has been no research on frangipani tree rhizosphere bacteria from burial grounds. The aim of this study was to investigate the phosphate-dissolving and blast disease-causing Pyricularia oryzae fungus-inhibiting properties of frangipani tree rhizosphere bacteria from Pracimaloyo cemetery, Surakarta. A total of 39 isolates of frangipani tree rhizosphere bacteria were tested for their ability to dissolve phosphates using PKA media (Pikovskaya), while the antagonism test against the fungal pathogen Pyricularia oryzae used the dual assay method. The results of the study showed that 15% of the rhizosphere bacteria of the frangipani tree were able to dissolve phosphate, and 33% of the isolates were able to inhibit the growth of the fungus Pyricularia oryzae with an inhibitory power of more than 40%. Based on the results, the rhizosphere bacterial isolates from Pracimaloyo TPU show the characteristics of a possible PGPR.

Abstract

A public cemetery (TPU) is land provided by the government to bury bodies. The culture of funerals in Indonesia is varied but generally involves being buried in the soil with wrapped clothes, covered wooden boards, and tombs. The material contains cellulose that will be broken down by cellulolytic microorganisms, including bacteria. The exploration of the cellulolytic bacteria of TPU in Indonesia has not been carried out, so this study aims to investigate and identify cellulose bacteria isolates from TPU. This research is a non-experimental study for the isolation of bacteria in the soil of TPU Bonoloyo, Surakarta. A selection of cellulite bacteria is grown in CMC media. Isolates that show cellulolytic activity are identified by observing colonial morphology and Gram coloring. Selection results of cellulolytic bacteria obtained isolates with cellulolytic index (IS) including a high category of 1 isolate (B14), a medium category of 3 isolates (B16, B27, and B45), and 9 low category isolates. The study concluded that 28.8 % showed cellulolytic activity with irregular morphological forms of white dyeing on flat surfaces with flat edges and dominated by gram-negative coccyx-shaped.

Abstract

In The Pracimaloyo Public Cemetery, the body’s decomposition occurs continuously, producing soil nutrients and minerals that affect the growth of bacteria. Bacterial population data from the cemetery area is still very limited, whereas cemeteries hold the risk of contamination with pathogenic bacteria. This research aims to find out how the population and diversity of bacteria in the Pracimaloyo Public Cemetery. Soil samples were taken from the Pracimaloyo cemetery at 2 locations (blocks 8 and 18), each at 20 and 50 cm depth. Soil samples are inoculated in Nutrient Agar media using the spread plate method. After 48 hours, colony counting, colony morphology, and gram staining observations were carried out. The rate of soil bacterial populations in blocks 8 and 18 at a depth of 20 cm was 4.23 × 107 CFU/g and 9.79 × 107 CFU/g, while at depths of 50 cm, it was 1.94 × 107 CFU/g and 1.92 × 107 CFU/g. The morphology of the bacterial colonies is dominated by circular shape, entire margin, flat elevation, and white color. 20 isolates are gram-negative and 16 isolates are gram-positive, the cell form is dominated by the bacillus.

Abstract

This study aimed to introduce Nusantara culture based on educational games by adjusting students' learning styles. Culture as an ancestral heritage tradition needs to be preserved by introducing it to the younger gen-eration from an early age. However, the survey results found that less than 26% of student respondents un-derstood Nusantara culture well. Compared to previous research, the model of cultural introduction through adaptive educational games is more fun because it is adapted to the way students learn. This research was carried out using the Design-Based Research (DBR) method through 4 stages of the procedure. The feasibil-ity test and application effectiveness test were carried out on a group of students from several elementary schools in Indonesia, who were taken using a cluster random sampling technique. The results of media design and content validation obtained an average value of 0.76 and 0.82, which means that the media is declared valid. The feasibility test used the System Usability Scale (SUS) with an average value of 80% in the acceptable category. The results of the research obtained a description of the comparison of the final scores of the control class and the experimental class, which was 55 compared to 75. This study concluded that learning media for introducing Indonesian culture based on adaptive educational games had a positive impact by effectively increasing learning outcomes on students' understanding of Indonesian culture. Further development of this game application can be expanded in the application of animation in more depth.

Abstract

One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.

Abstract

Background: A public cemetery (TPU) is where bodies are buried. Before being buried, the body is wrapped in a shroud or full clothes and sometimes put in a coffin. These materials contain cellulose, a substrate for cellulolytic microorganisms, including bacteria, to decompose. Exploration of cellulolytic bacteria in TPU has not been found, even though TPU holds potential cellulolytic bodies. This study aims to determine the cellulolytic potential and identify bacterial isolates from TPU. Methods: 36 bacterial isolates tested for cellulolytic potential have been isolated from TPU Pracimaloyo Kartasura, Sukoharjo. Selection of cellulolytic bacteria used selective Carboxymethyl Cellulose (CMC) media dripped with Congo red 0.1%, while identification was based on colony morphology and Gram staining. Results: This study obtained one isolate (2.78%) showing high cellulolytic activity with a cellulolytic index (IS) 7, namely P14, 24 isolates (66.67%) in the "moderate" category, four isolates (11.11%) with category "low," and seven isolates (19.44%) did not show cellulolytic ability. Isolates cellulolytic positive have a shiny white colony color, entire edges, raised elevation, and belong to the Gram-negative coccus form. Conclusions: From the results of this study, it can be concluded that public burial sites (TPU) harbor potential cellulolytic bacteria.

Abstract

Background: Plants’ response and antagonistic reaction against disease-causing organisms are two crucial characteristics of Plant Growth Promoting Bacteria (PGPB). Seventeen endophytic bacteria have been isolated from Musa balbisiana. However, the plants’ reaction against these isolates and their antagonistic activities against disease-causing organisms remained unknown. This study aims to (1) determine the sensitivity effect of endophytic bacteria isolates to tobacco and (2) test the antagonism of endophytic bacteria isolates against the blast disease actor, namely Pyricularia oryzae. Method: Sensitivity tests were performed by inoculating bacterial isolates into tobacco leaves with infiltration. Bacterial isolates were prepared with a minimum OD 600: 0.5. Then, a milliliter volume of each isolate was infiltrated into tobacco leaves from the abaxial side using a 3 mL syringe. The lesion on the tobacco leaves was observed seven days after inoculation (DAI). The antagonism test was carried out by growing Pyricularia oryzae on a PDA plate for seven days, subsequently transferred to an NA medium for three days then inoculated with endophytic bacteria. The assessed parameter of the antagonistic test was the formation of an inhibitory zone between endophytic bacteria and Pyricularia oryzae at 4 DAI. Results: No hypersensitive reaction of tobacco leaves against K117, K324, K38, K86, K18, K28, K102 isolates inoculation at 7 DAI. Furthermore, the antagonistic test indicated that all isolates inhibited the growth of Pyricularia oryzae, with the range of inhibition from 32.36 to 40.46%. Implication: Thus, these results revealed the PGPB characteristics in the newly isolated endophytic bacteria from the banana.
