Abstract

Srimenganten Village, located in Pulau Panggung Sub-district, Tanggamus Regency, Lampung Province, is an agrarian area with vanilla as one of its main commodities. However, vanilla productivity in this village has declined due to the outbreak of Vanilla Stem Rot Disease (BBV), caused by the fungus Fusarium oxysporum f.sp. vanillae. To address this issue, a community service program was conducted through training on BBV disease management for vanilla farmers in Srimenganten Village. The training covered topics such as disease symptom identification, prevention methods, and environmentally friendly control techniques. The effectiveness of the training was evaluated by comparing participants' pre-test and post-test results. The evaluation showed an average increase in participants' knowledge scores by 33.3 points, with a percentage increase of 61.3%. This indicates that the training effectively enhanced farmers' understanding of BBV disease management. It is expected that this increased knowledge will be applied in vanilla cultivation practices, thereby improving productivity and the quality of harvests.

Abstract

Tempe is a traditional Indonesian food product obtained through a fermentation process that utilizes the activity of molds from the genus Rhizopus sp. on soybeans. Oxygen availability plays a crucial role in tempe fermentation, as Rhizopus sp. is an obligate aerobic mold that requires oxygen for optimal growth. This study was conducted to examine the extent to which oxygen availability affects the growth of Rhizopus sp. during the tempe fermentation process, while also serving as a practical application of traditional biotechnology in daily life. The study employed an experimental design with three different packaging treatments: banana leaves, perforated plastic, and non-perforated plastic. Fermentation took place over 48 hours at a temperature of 30–32°C. Observations of mycelium growth were conducted every 12 hours, focusing on several indicators: color, hyphal density, and the surface area covered by mycelium. These observations were supplemented by an assessment of tempeh’s physical quality, encompassing color, aroma, texture, and firmness. Based on the research results, it was found that the use of banana leaf packaging produced the densest, most even, and purest white mycelium growth, while also yielding tempeh with the highest physical quality and nutritional content compared to other types of packaging. Perforated plastic packaging yielded fairly good results, whereas non-perforated plastic packaging produced tempeh of the lowest quality due to restricted air circulation. It can be concluded that oxygen availability has a significant effect on the growth of Rhizopus sp. and the quality of the resulting tempeh. The better the air circulation within the packaging, the more optimal the fermentation process and the quality of the resulting tempe.

Abstract

Aquaculture activities generate various types of waste that can potentially degrade environmental quality if not properly managed. As an institution dedicated to the development of marine aquaculture, the Lampung Marine Aquaculture Center (BBPBL) has implemented a waste management system to preserve the aquatic environment. This study aims to examine the waste management system implemented in fish farming activities within the BBPBL Lampung facility, located in Pesawaran District, South Lampung. The approach used is qualitative descriptive, employing data collection techniques such as direct field observations, structured interviews, and a review of relevant documents. All collected data were then analyzed narratively to describe the types of waste generated and the sequence of their management processes. The findings revealed that the generated waste includes organic solid waste, wastewater, chemical residues, biological waste, residues from processing and post-harvest activities, as well as waste classified as hazardous and toxic materials. Wastewater treatment is carried out through a Wastewater Treatment Plant (WWTP), which includes the stages of collection, separation of contaminants, particle sedimentation, and regulation of chemical levels before the effluent is released back into the environment. The implementation of this system has proven effective in reducing the amount of pollutants such as dissolved solids, organic compounds, and chemical residues, thereby minimizing the risk of environmental pollution. Therefore, the implementation of an integrated wastewater management system at the Lampung Aquaculture Research and Development Center plays a strategic role in maintaining the quality of aquatic environments while supporting the sustainability of aquaculture operations.

Abstract

Water quality is one of the key factors determining the success of grouper aquaculture because it affects the growth, health, and survival of the fish. Proper water quality management requires monitoring important parameters, such as temperature, pH, and dissolved oxygen (DO), to ensure that water conditions remain within a range suitable for the biological needs of the fish. This study aims to evaluate water quality management based on pH, temperature, and dissolved oxygen (DO) parameters in grouper aquaculture at the Lampung Marine Aquaculture Research and Development Center (BBPBL). The study employed a descriptive method with a qualitative approach. Data were collected through semi-structured interviews with managers, direct observations during site visits, documentation of water quality monitoring results obtained from the Lampung Marine Aquaculture Center (BBPBL), and a literature review. The data were analyzed descriptively by comparing the results of water quality management against the recommended parameter ranges cited in various scientific literature. The results of the study indicate that water quality management at the Lampung BBPBL is carried out through routine monitoring of temperature, pH, and dissolved oxygen parameters as an effort to maintain optimal aquaculture environmental conditions. Based on the evaluation results, water quality management has been implemented in accordance with the needs of grouper aquaculture, thereby supporting environmental conditions conducive to fish growth and survival. Therefore, periodic monitoring and management of water quality must be maintained as part of efforts to improve the effectiveness of grouper aquaculture.

Abstract

Biology teachers' competence in utilizing laboratory facilities as learning media plays an important role in developing students' scientific skills. However, the application of plant tissue culture techniques as a practical component of biotechnology learning is still limited in many secondary schools. This community service program aimed to strengthen the competence of senior high school Biology teachers through plant tissue culture training conducted at SMAN 1 Wonosobo, Tanggamus Regency, Lampung. The program consisted of lectures, demonstrations, hands-on laboratory practice, and learning evaluation using pre-test and post-test assessments. The training materials covered the basic principles of plant tissue culture, sterilization techniques, culture media preparation, explant inoculation, subculturing, and plantlet maintenance. The evaluation results showed that the participants' average knowledge score increased from 39.8% before the training to 88.0% after the training, representing an improvement of 48.2 percentage points. These findings indicate that the training program was effective in enhancing teachers' knowledge and practical skills in plant tissue culture techniques. The improved competence is expected to support the implementation of laboratory-based biology learning and promote the development of students' scientific skills in secondary schools.
