Abstract

Reproductive health is one of the knowledge that is still taboo in society. In fact, it is very important for reproductive development. In adolescents, physical, mental, and social changes must be balanced with good and correct knowledge. Thus, a healthy and quality generation can be created. Way Dadi Village, is one of the villages located in Sukarame District, Bandar Lampung City with a fairly high number of teenagers and adults. This Community Service (PKM) aims to provide knowledge to the public about the importance of reproductive health in maintaining the quality of generations and provide knowledge about the importance of knowing the potential of Medicinal Plants (TOGA) which can be used as prevention of reproductive diseases. This PKM is carried out with a face-to-face method in accordance with health protocols. The PKM method is carried out by evaluating the pre-instruction and post-instruction research questionnaires. Filling in is based on the weighting of understanding starting from not, enough, moderate, good, and very good. Thus, the final post-exam results are obtained with a very good average understanding of up to 86%.

Abstract

Rice is an important food crop in Indonesia, where more than 50% of the Indonesian population consumes rice as a staple food. Rice has decreased productivity by 50-80% due to bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo). The rapid spread and damaging effects of pesticide use on the environment are the main obstacles in the treatment of these bacteria. Alternative control is to use biological agents in the form of phosphate solubilizing bacteria (PSB). Phosphate-solubilizing bacteria are part of the growth-promoting bacteria that have other abilities, namely biocontrol. The purpose of this study was to develop the ability of acid soil phosphate solubilizing bacteria to inhibit growth in vitro. The test was carried out using the dual culture technique with the zone of inhibition method. The results showed that ten isolates of PSB had inhibition against Xoo with various diameters of inhibition. The four highest inhibitory isolates were EF.NAP 3 (5.267 ± 0.189 mm), Pseudomonas GSP 6 (4533 ± 0.772 mm), EF.NAP 4 (3,424 ± 0.161 mm) and EF. NAP 9 (3.167±0.136 mm). The ability of PSB to inhibit Xoo can be used as an alternative in controlling bacterial leaf blight in rice plants. This indicates that the PSB isolate acts as a biostimulant in the dissolution of phosphate in the soil and as a bioprotectant.

Abstract

Nitrogen (N) is naturally available in the form of N2. Nitrogen fixation can be facilitated by microbes such as Rhizobium bacteria, which can establish symbiosis with the roots of legume plants to form root nodules that perform nitrogen fixation. This study aims to determine the characteristics of Rhizobium bacteria in the root nodules of peanuts (Arachis hypogaea) and koro rawe (Mucuna bracteata). The methods used in this research include collecting root nodules, isolating Rhizobium bacteria, and identifying and characterizing these bacteria for their nitrogen fixation and phosphate solubilization capabilities. Characterization results on YEMA + Congo red media indicated that 10 out of 16 isolates from peanut root nodules and 30 out of 55 isolates from koro rawe root nodules were positive for Rhizobium bacteria. The nitrogen fixation activity test revealed that only 4 isolates from peanut root nodules and 6 from koro rawe root nodules exhibited nitrogen fixation ability in Jensen's medium. The highest phosphate solubilization index was obtained from isolate KK.5.1.1 (0.5±0.08), while the lowest was from isolate KK.5.2.2 (0.09±0.06). This research underscores the significance of Rhizobium in enhancing nitrogen availability and phosphate solubilization for legume plants.

Abstract

ABSTRAK Pandemi global mengharuskan masyarakat untuk memberikan perhatian lebih terhadap peningkatan daya tahan tubuh agar tidak mudah terpapar berbagai penyakit terutama Covid-19. Ada banyak cara yang dapat dilakukan untuk meningkatkan imunitas tubuh, salah satunya dengan mengkonsumsi makanan dari produk alami bebas bahan kimia berbahaya yang mengandung nutrisi seimbang. Salah satu produk alami yang dapat meningkatkan daya tahan tubuh adalah madu. Madu merupakan salah satu produk alami lebah yang dapat langsung dikonsumsi dan berkhasiat untuk kesehatan. Lebah yang umumnya dipelihara untuk menghasilkan madu adalah jenis lebah madu Apis sp. yang memiliki sengat. Hal ini yang menyebabkan madu hanya bisa diperoleh dari peternak lebah dan distributor madu. Namun, jenis lebah liar tanpa sengat dapat mempermudah masyarakat untuk memperoleh madu dan dapat dipelihara langsung dari rumah. Pengetahuan pemeliharaan lebah madu dapat membantu masyarakat untuk memastikan tersedianya asupan nutrisi yang dapat menjaga daya tahan tubuh keluarga. Pelaksanaan pelatihan pemeliharaan lebah tanpa sengat dilaksanakan dengan metoda ceramah di Desa Bumisari, Natar, Lampung Selatan. Tahapan pelaksanaan kegiatan ini meliputi pengisian kuesioner pre-test dan post-test untuk mengetahui pengetahuan masyarakat sebelum dan sesudah dilakasanakan pelatihan. Ketercapaian target diketahui dapat berdasarkan hasil analisis kuesioner yang dilakukan, dimana ditemukan peningkatan pemahaman masyarakat hingga 87.096%. Berdasarkan hasil akhir kegiatan, diharapkan masyarakat semakin baik mengelola lingkungan sekitar sehingga sumber tanaman penghasil nektar untuk madu lebah tanpa sengat tetap terus tersedia. Kata kunci: daya tahan tubuh, lebah tanpa sengat, madu, desa Bumisari ABSTRACT People need to focus more on strengthening their immune systems in order to avoid being easily exposed to numerous diseases, including COVID-19. There are many things that can be done to increase the body's immunity, one of which is by consuming foods derived from natural products that free of harmful chemicals and contain a balanced of nutrients. Honey is one of the natural bee products that can be consumed right away and is good for human health. Apis spp., is the common insect species of bees with sting, are typically kept to generate honey. Because of this, good quality honey is only available from professional beekeepers and honey suppliers. However, wild stingless bees can help people to obtain honey and can be kept at home. Knowledge of honey bee maintenance can help the community to ensure the availability of nutritional intake that can maintain the family's immune system. The implementation of stingless beekeeping training was carried out using the lecture method in Bumisari Village, Natar, South Lampung. The stages of implementing this activity include filling out pre-test and post-test questionnaires to determine community knowledge before and after the training. The achievement of the target can be known based on the results of the questionnaire analysis conducted, which found an increase in public understanding of up to 87.096%. Based on the final results of the activity, it is hoped that the community will better manage the surrounding environment so that sources of nectar-producing plants for stingless bee honey will continue to be available. Keywords: immune system, stingless bee, honey, Bumisari village

Abstract

The global increase in multidrug-resistant (MDR) bacterial infection has rapidly gained concern globally. This study aimed to investigate antibacterial and antibiofilm potential of 25 soil actinomycete strains against MDR strains including Escherichia coli strain M4, Pseudomonas aeruginosa strain M19, Klebsiella pneumoniae strain M19, Bacillus subtilis strain M18, and Methicillin Resistant Staphylococcus aureus (MRSA). In this study, three actinomycete isolates encoded APM-7, APM-11, and APM-21 showed a strong and broad antibacterial spectrum. The minimum inhibitory concentration (MIC) of extracts derived from these isolates was ranged from 78 μg/ml to 10,000 μg/ml. In addition, The extracts also displayed significant biofilm inhibition values ranging from 6.06 to 72.4%. Based on the results, APM-21 extract had the best antibacterial and antibiofilm activities with the strongest values against MRSA. According to the nucleotide sequencing of the 16S rRNA gene, APM-7, APM-11, and APM-21 strains possessed similar identities with Streptomyces cyaneus, Streptomyces coerulescens, and Streptomyces panayensis, respectively. Based on Liquid Chromatography Tandem-Mass Spectrometry (LC-MS/MS) analysis, two antibacterial compounds, namely rancimanycin III, and enteromycin were detected in all those three extracts. Interestingly, APM-21 extract also contained two prominent antibacterial substances including paramagnetoquinone C, and caerulomycin I, suggesting their contribution to the most potential activities. Moreover, new insights were provided into a promising candidate for use in an active compound combating strategy to control MDR bacterial strain infection.

Abstract

Background: Oil palm empty fruit bunches (OPEFB) represent the largest form of solid waste generated from palm oil production, comprising approximately 23 % of the weight of every ton of fresh fruit bunches (FFB) processed. Untreated OPEFB waste causing pollution problems and increase toxicity due to methane emission. This study aims to evaluate the potential of OPEFB as a growth substrate for the cultivation of Pleurotus ostreatus and Volvariella volvacea, as well as to assess the reduction in lignocellulosic content following fungal biodegradation. Methodology: The experiment was conducted using solid-state fermentation (SSF), and lignocellulose content was analyzed using the Chesson method and SNI 0429:2008 through descriptive quantitative analysis. Findings: Over a 21-day incubation period, mycelial growth of both fungi successfully colonized the OPEFB baglogs, resulting in a 1–2 % reduction in baglog weight. Both P. ostreatus and V. volvacea demonstrated the ability to degrade lignocellulose by secreting lignin peroxidase (LiP), manganese peroxidase (MnP), laccase, cellulase, and hemicellulase enzymes. Initial lignocellulose levels of OPEFB were 18 % lignin, 57 % cellulose, and 20 % hemicellulose. After 21 days of incubation, P. ostreatus reduced these levels to 10 %  lignin, 47 % cellulose, and 19 % hemicellulose, while V. volvacea reduced them to 11 % lignin, 52 % cellulose, and 18 % hemicellulose. Contribution: These findings indicate that OPEFB is a viable substrate for mushroom cultivation and can be effectively biodegraded by these fungi, offering a sustainable approach to managing palm oil industry waste. The treated OPEFB can be used as organic fertilizer, animal feed, and briquettes
