Dragon fruit plants originating from Central and South America have not been widely cultivated. This plant has only been cultivated intensively in several countries such as: Israel, Colombia, Nicaragua, Vietnam, Thailand, China and Australia. Macroscopic identification showed that the fungi associated with dragon fruit stems had similarities to the colony form of Colletotrichum gloeosporioides sp. Trichoderma is known to have antagonistic abilities against pathogenic fungi. Trichoderma is easily found in soil ecosystems and plant roots. The method in this study is a survey method. Determination of the sample using purposive sampling or Judgmental sampling method, namely purposive sampling is a sampling method that selects objects (vines) that are considered attacked or have symptoms of pathogen attack. Trichoderma sp is also tolerant to stress and able to inactivate pathogenic microbial enzymes. In addition, Trichoderma sp. Able to produce enzymes that hydrolyze pathogenic cell walls which will inhibit the synthesis of pathogenic cell walls and increase their fungicidal activity, as a result of which pathogenic fungi experience a decrease in growth rate.

Participation from all parties is important in post-disaster rehabilitation and reconstruction because it is the most complex activity in disaster management from the planning process, funding, and implementation. A Tsunami that struck Sunda strait in December 2018 caused a great loss and immediate response is necessary. The delay of rehabilitation and reconstructions affected the stability of national security. Therefore, all parties need to take part in post-tsunami recovery so that the disaster recovery process implemented effectively and efficiently. The purpose of this study was to analyze the participation of society in the post-tsunami rehabilitation and reconstruction management in Pandeglang district, coordination networking, and contributions to national security. The qualitative method is used in this research from the primary and secondary databases. For the purposes of this study, the primary data were gathered through face-to-face interviews from the subjects of research who were chosen based on purposive sampling and snowball methods. The data analyzed qualitatively and simulation by UCINET 6 is used for coordination networking. The result shows that all parties had taken part in the Pandeglang post-tsunami recovery management from the planning process, implementation, monitoring, and evaluations. The level and form of community participation are diverse.

Banda Aceh, a coastal city located in the western most province of Indonesia, has long been known for its stunning natural beauty and vibrant cultural heritage. Situated on the northern tip of Sumatra Island, this bustling city is surrounded by the vast expanse of the Indian Ocean on one side and picturesque hills on the other. However, beneath its picturesque facade lies an alarming reality - Banda Aceh stands perilously exposed to a high risk of disaster.. With the history of disasters in Aceh which is one of the biggest disasters that has caused many casualties, education related to disaster awareness needs to be carried out. People with hearing  disabilities are one of the vulnerable groups in the event of a disaster. Education related to disaster awareness is a form of non-structural mitigation which at this time has been widely carried out both in formal education in schools and campuses and informally in the community. Efforts to increase disaster awareness through education are important, including for groups with disabilities . As a group with hearing impairments, they are at greater risk when a disaster occurs because they cannot hear warnings through sound media and the communications gap. However, with disaster awareness through education, people with disabilities are also expected to be able to carry out independent evacuations and save themselves when a disaster occurs. This research aimed to explore the effectiveness of designing disaster media education for children with disabilities in Banda Aceh, Indonesia. Recognizing the unique vulnerabilities of children with disabilities during disasters, the study focused on developing an inclusive and accessible media-based educational program. The method used in the research is qualitative research and encompassed various stages, including needs assessment, program development and implementation. Designing disaster media education for children with disabilities in Banda Aceh proved to be an effective and essential approach to bridge the education gap and enhance disaster preparedness among this marginalized group. The research outcomes emphasize the importance of inclusive and accessible education in disaster management, aiming to ensure the safety and well-being of all children, regardless of their abilities. The findings of this research contribute to the growing body of knowledge on disability-inclusive disaster education and provide a basis for future program development and policy-making in disaster management in Banda Aceh and beyond.
