Faculty of Biology, Universitas Gadjah Mada, responded to the waste emergency situation in Yogyakarta following the closure of the Piyungan Final Disposal Site (TPA), which has been the main landfill for final disposal in the Yogyakarta Province (DIY) area. Based on a circular letter from the Regional Secretariat of the DIY Government, the Piyungan Regional TPA will no longer receive waste services as of July 23, 2023 to September 5, 2023 due to the fact that the amount of waste is full and exceeds capacity. Universitas Gadjah Mada through the Faculty of Biology and the Faculty of Dentistry responded by following up on waste management at UGM internally where the coordination of organic waste management is carried out by the Faculty of Biology while the coordination of inorganic waste management is carried out by the Faculty of Dentistry.

As of Thursday, 27 July 2023, Dean of the Faculty of Biology UGM, Prof. Dr. Budi Setiadi Daryono, M.Agr.Sc., has coordinated with the Chancellor of Universitas Gadjah Mada, Prof. dr. Ova Emilia, M.Med.Ed., Sp.OG(K)., Ph.D., and Director of DPKM (Directorate of Community Service) Universitas Gadjah Mada, Dr. dr. Rustamaji, M. Kes. It has been agreed that the Faculty of Biology will manage internal organic waste from Universitas Gadjah Mada in the form of leaf and twig litter. The collection of organic waste will be coordinated at each unit point in all UGM areas to be enumerated first and then sent and managed by the Faculty of Biology to become organic compost. Meanwhile, organic waste in the form of food scraps, fruit and vegetables will be managed by the UGM Argotechnology Innovation Center (PIAT).

The management of leaf litter and twigs in the Faculty of Biology has been going on for a long time in the Biology Garden Area, Faculty of Biology. The chopped organic waste will be processed into compost and then supplied to consumers in collaboration with PT. Pagilaran. The establishment of the Waste Management Center as a response to the closure of the Piyungan TPA will then be coordinated with Soenarwan Heri Purwanto, S.Si., M.Kes. and the waste management team from the Faculty of Biology.

This waste management initiative is a form of commitment from the Faculty of Biology UGM to contribute to the sustainability environment, especially in UGM’s internal environment. It is hoped that this management program will be useful in the long-term settlement of internal waste at UGM in particular and in the Special Region of Yogyakarta (DIY) in general.

On 12-15 July 2022, Lecturer at the Faculty of Biology UGM Akbar Reza, M.Sc and Puji Lestari, S. Hut, M.Sc lecturers at the Department of Biology and Veterinary Technology at the UGM Vocational School carried out research and community service activities in Kotabaru, South Kalimantan, particularly Hilir Muara Village and Gedambaan Village. The activity which is a cross-sectoral collaboration between the Social Development Studies Center (SODEC) UGM, Faculty of Biology UGM, PT. Mubadala Energy, Kotabaru Polytechnic and the local government have been implementing this since 2020. Activities in Hilir Muara Village focus on empowering coastal communities with main assistance to Pokdarlis (Environmental Awareness Group), UMKM (Hilir Muara Cinta Bumi), and Waste Bank. Some of the programs initiated include greenhouses establishment for plants with economic value and native of Kalimantan, optimizing composters, including initiating collaboration with BUMDES and assisting BPOM’s licensing process for UMKM. These programs were initiated out of concern for the sustainability of coastal ecosystems which actually provide high ecosystem services, especially in the face of the climate crisis. Furthermore, the waste problem is also a problem for coastal areas which, apart from reducing aesthetics, also has the potential to cause long-term health problems.

Activities continued in Gedambaan Village which focused on studying coastal biodiversity. On this occasion, Akbar Reza, M.Sc with an expertise on ecology and conservation, and Puji Lestari, S.Hut, M.Sc with an expertise on Forestry were responsible for justifying techniques and locations for planting mangroves, determining permanent plots (PUP), and monitoring methods as an initiation for long-term monitoring. In its implementation, this activity was intensely assisted by Fitra Nofra, S.Si and Gema Starliantri, S.Hut as the Biodiversity Officer of PT. Mubadala Energy, in collaboration with the Kotabaru Polytechnic and the Gedambaan Village Government as the main actors. On the same occasion, planning was also carried out for a program for planting typical Kalimantan plants in collaboration with the Pulau Laut Sebuku  in the Environmental Services Block in the Bukit Mamake area. Furthermore, in the long term these programs are expected to have economic value that can support the lives of local communities.

In general, these research activities and empowerment programs simultaneously support national programs such as PROKLIM Village, climate change adaptation, and local community-based blue carbon ecosystem preservation. It is hoped that the programs implemented will actually be able to help coastal communities as vulnerable to climate change. In addition, the programs are expected to be able to bring about change, both from an environmental and economic perspective

MBKM-PkM activities was started by distributing questionnaires on Saturday and Sunday of 20 and 21 May 2023 to the residents of Dusun Pajangan using the door-to-door method. The aim of the questionnaire was to find out the community’s understanding of degenerative diseases, the condition of vacant lands in Dusun Pajangan, as well as the potential of medicinal and vegetable plants to prevent degenerative diseases. Through distributing this questionnaire, 40 respondents were found with an age range of 15-69 years. Among them, 33 respondents had never heard of degenerative diseases. Based on these results, we found out that most residents of Pajangan think that an unhealthy lifestyle and stress are the main triggers of degenerative diseases. Then, based on the several examples of degenerative diseases mentioned, people are more familiar with high blood pressure (hypertension) and diabetes mellitus, while 7 of them did not know the examples of degenerative diseases. Furthermore, through distributing this questionnaire, it was revealed that there were several vacant lands in Dusun Pajangan, most of which had not been used optimally other than for gardening and for waste disposal. In addition, we also obtained data that 29 out of 40 respondents already knew about medicinal and vegetable plants, plant samples, and some of their uses. Most people in Dusun Pajangan also use medicinal plants as herbal medicine.

Then, to further increase public understanding of degenerative diseases, our team has also conducted socialization or outreach programs about degenerative diseases and the potential of several plants as preventative alternative treatment on June 4, 2023 at 10.00-12.00 WIB. This program aims to increase the understanding of the Dusun Pajangan community about degenerative disease, the factors that affect degenerative diseases, as well as the potential of some plants to prevent these diseases. The socialization which was attended by 17 residents of Dusun Pajangan received positive responses. Besides that, our team also made an inventory of several medicinal and vegetable plants in Dusun Pajangan which aimed to find out what medicinal plants are often used by the community. Based on the results of the inventory, there are several medicinal and functional plants that are widely grown by the people in Dusun Pajangan, including ginger, galangal, betel, aloe vera, Indian mulberry, papaya, banana, guava, butterfly pea, pandan leaves, taro leaves, and many more.

In order to introduce waste management techniques, the team of Pengabdian Kepada Masyarakat – Merdeka Belajar Kampus Merdeka (PkM MBKM) Faculty of Biology 2023 chaired by Rina Sri Kasiamdari, S.Si., Ph.D. and involved two students namely Galuh Kirana Mahadewi and Laila Uswatun Chasanah have carried out activities related to organic waste management in Dusun Kepuh Kulon RT 001, Wirokerten, Banguntapan, Bantul. This activity is planned to take place in 2 semesters, starting with a socialization event which have been held on Sunday 14 May 2023 from 09.00 to 10.30 WIB at the house of the neighborhood head of RT 001, Mr. Zamzuri. This socialization activity was attended by 15 participants of RT 001 and the head of Hamlet. In her greetings, Ms. Rina said that the MBKM PkM activity was the second year of the MBKM PkM Program at RT 001 Kepuh Kulon. The Waste Management theme is a program that is expected to be applied by people in their homes or in their environment. Head of the hamlet, Mr. Sunartana conveyed the importance of household-scale waste management. This is because a lot of garbage has accumulated in various places due to garbage dumps that can no longer accommodate waste. In this socialization activity, it was explained the meaning of waste, types of waste, examples, as well as how to process waste into more useful items.

After the socialization activities were carried out, then practical activities were carried out in managing household organic waste into compost and eco enzymes. This activity was held on Sunday, 21 May 2023 from 09.30 to 11.00 WIB at the house of the neighborhood head of RT 001, Mr. Zamzuri. This activity was attended by 23 participants consisting of women from Kepuh Kulon RT 001. Before doing the practice, Galuh and Laila demonstrated how to make compost and eco enzymes from household waste. In this activity, Rania Naura Anindhita, a student at the UGM Faculty of Biology, introduced her product to the participants who attended. Eco Lindi is a liquid that neutralizes the smell of garbage, the smell of garbage sprayed by Eco Lindi will disappear within 10 minutes. During the practice of making compost and eco enzymes, the community was divided into four groups, one group consisting of 5 to 6 people and each group carried out independent practices. The waste used comes from household waste collected a few days before. At the end of the activity, the MBKM PkM team distributed EM4, molasses, and Eco Lindi to the participants that attend, so they could re-practice making the compost and eco enzyme at their homes. Eco Lindi that is distributed can be sprayed to remove the smell of household waste, chicken coops, or cattle houses. This PkM MBKM activity will be continued from July to November with the utilization of household waste into more useful materials.

Two Biology students Class of 2019 who are members of the “Organic Sheet Mulch” team under the guidance of Dwi Umi Siswanti, S.Sc., M.Sc. won a bronze medal on March 21, 2023 in an international scientific work competition. The team chaired by Vykra Aulia Firdiana with one member, namely Fatika Soraya Taufik took part in the Agritech Research and Entrepreneurship Innovation (AGREETION) competition which was held in cooperation with several organizations at the Faculty of Agricultural Technology, University of Brawijaya, including the Agritech Research and Study Club (ARSC), Agritechno Business Center (ABC), Agricultural Industrial Technology Student Association (HIMATITAN), Agricultural Engineering Student Association (HIMATETA), and Agricultural Product Technology Student Association (HIMALOGISTA). This competition takes place from 1 February 2023 to. 21 March 2023 and was successfully attended by 243 teams from three countries (Indonesia, Malaysia and the Philippines).

The big theme that was carried out in this competition was “Development and Innovation on Sustainable Agro-Based Industry Technology to Achieve Human Welfare” with 4 sub-themes. In this competition, Vykra and Soraya compiled a scientific work on the sub-theme “Green Agroindustry and Bio-economy” entitled “Organic Mulch from Sewage Sludge and Banana Pseudostem Waste to Reduce the Impact of Drought Due to El Nino Phenomenon on Horticultural Crops to Improve Human Welfare”. The problem behind the preparation of this scientific work is the statement by the National Disaster Management Agency (BNPB) and the Meteorology, Climatology and Geophysics Agency (BMKG) regarding an increase in drought up to three times worse due to an increase in the El Nino index which is predicted to occur in mid-2023. This has the potential to further increase puso (parched) due to drought which has long been a problem for farmers despite the low El Nino index.

In this scientific work, sewage sludge and banana leaf waste are used as organic mulches which are able to maintain soil water content during the drought phase so that soil moisture is maintained. The organic materials contained in this mulch innovation also add to the role of mulch as a supplier of additional nutrients to the soil to support optimal plant growth. The use of these two materials is an effort to utilize biowaste and create a green agroindustry. The hope is that this innovation can be used as a reference in anticipating and reducing puso due to drought

On March 18, 2023, a presentation on the Business Plan ENVIROTECH 4.0 innovation by PT Pertamina Hulu Indonesia was held with the sub-theme of organic solid waste management, as well as commemorating World Waste Recycling Day. The STARGAZE team fronted by Eva Yunizar Reza Permana Putri, Fanny Najmi Faza, and Fika Zulfiani participated in the competition. The title raised was “MoldtoPlast” Product Innovation of Aspergillus niger Spore Suspension as a Biodegradation Agent for Plastic Packaging Waste” under the assistance of Dr. Miftahul Ilmi, S.Si., M.Sc.

The use of plastic, especially plastic packaging, is increasing. This of course has a bad impact on the environment because plastic waste has a long recycling period. The STARGAZE team looks at the potential for microorganisms that have the ability to degrade plastic, one of which is mold, which is an alternative in the biodegradation of plastic waste made from Low Density Polyethylene (LDPE). The innovative product in the form of Aspergillus niger Spore Suspension is packaged in powder form and environmentally friendly paper packaging. This product is targeted to a wide range of markets due to its effectiveness and environmental friendliness.

Prof. Michael Sauer, Deputy Head of The Institute of Microbiology and Microbial Biotechnology, BOKU University, Vienna, Austria gave a Guest Lecture to students, lecturers and researchers at the Auditorium of the Faculty of Biology, UGM. Topics presented were about bioprocess and biorefinery. The guest lecture was opened by the Vice Dean for Research and Community Service and Alumni, Dr. Eko Agus Suyono who is also the moderator on the agenda. In the guest lecture, it was conveyed that the world is experiencing a sustainability problem. One of the main causes is environmental pollution, especially from plastic waste.

Indonesia, which is a mega-biodiversity country, has natural wealth potential that can be utilized as a source of raw materials for bioplastic production. Organisms such as bacteria and fungi are sources of bioplastic microorganisms that are widely found in Indonesia. However, the research and development in this matter is hardly enough to get attention.

Guest lectures that invite speakers from outside UGM are routine activities held by the Faculty of Biology UGM. With these activities, students will gain insight and material from experts related to the world of biology. Meanwhile, the partner network of the Faculty of Biology UGM will be accelerated and institutional recognition will also increase.

On Wednesday 8 February 2023, the Faculty of Biology UGM received a visit from the Vice Chancellor for Student Affairs, Community Service, and UGM Alumni, Dr. Arie Sujito, S.Sos., M.Sc., UGM Director of Community Service, Dr. dr. Rustamaji, M.Kes., and Director Secretary of Community Service UGM, Dr. Djarot Heru Santosa, M.Hum. The visit began with a discussion on program development in the KPTU Meeting Room of the Faculty of Biology UGM, followed by a tour around the campus of the UGM Faculty of Biology to review the production sites of POC (Liquid Organic Fertilizer) and organic fertilizers produced by the Faculty of Biology.

Dr. Arie Sujito, S.Sos., M.Sc., expressed the importance of community participation around the UGM campus to participate in activities carried out by UGM such as KKN, Research and Community Service. There are 3 very strategic hamlets that are the belt of UGM, namely Sagan hamlet, Blimbingsari hamlet and Terban hamlet. UGM will provide assistance to the community around the UGM campus to be able to supply the needs of UGM and hotels around the UGM campus.

On that occasion, they also discussed the IUP (International Undergraduate Program) program at the Faculty of Biology UGM which has been running and this year there will be the first batch of graduates. The IUP program also provides opportunities for students to take part in KKN activities organized by the university, but in practice there are still some obstacles which yet to be solved, for example the number of credits that must be taken, the time for the KKN to be carried out. Dr. Djarot Heru Santosa, M.Hum., will report and discuss this problem at the university level in order to get the best solution and can be applied to this year’s KKN.

The UGM Faculty of Biology will also play an active role in the management of organic waste generated from the environment around UGM and internally from UGM. The waste will be processed into organic fertilizer and POC which can then be reused by the community around the UGM campus, and can also be sold to earn UGM income.

Biology undergraduate students at Gadjah Mada University made another achievement at the national level by winning 3rd place in the National Scientific Writing Competition. This achievement was achieved by students Susy Wijayanti and Umi Salamah from Biology Class of 2018 under the guidance of Dr. Ardaning Nuriliani, S. Si., M. Kes. This competition is a competition held by the University of North Sumatra with the theme “Gen Z Innovation and Strategy in the Environmentally Friendly Living Movement”. This activity aims to be a forum for channeling student creations & innovations for a healthy generation.

This final activity took place on November 25 2022 online at the University of North Sumatra which was attended by students from universities throughout Indonesia. This competition was carried out in four stages, which were abstract submission, assessment of scientific papers, announcement of the top 10, and the culmination of which was the presentation of the paper in front of the judges.

In this competition the team raised the title “Phytoremediation of Domestic, Industrial and Agricultural Liquid Waste by Photobioreactor-Based Microalgae”. According to the team, the idea was motivated by the high increase in global population, industrialization, and economic progress which had an impact on increasing waste and decreasing water quality. This prompted the team to conduct research to find an efficient method of managing this waste. One of the biological agents that can act as a natural bioremediator for managing waste is microalgae. Hence, the waste becomes safer for the environment.

Team preparation was carried out a week before the online presentation activities by preparing presentation materials and materials. The team regularly practices so that they are able to provide clear and firm explanations of the papers being presented. The team was able to convey ideas and answer all the jury’s questions straightforwardly. They said that this was none other than the result of the team’s hard work and the support of all parties.

With this competition, they really hope to be able to provide encouragement and support for students who are interested in the field of scientific work to convey their best ideas through their intelligence in thinking. In addition, the team also hopes that through this competition it can bring and make the Faculty of Biology and Gadjah Mada University proud in the future.

On July 17^th, 2022, undergraduate students from the Faculty of Biology won 1^st place in the National Scientific Writing Competition organized by Universitas Brawijaya, out of eighty teams from universities across Indonesia that participated in this competition. The team consists of Umi Salamah, Maria Bening Wohingati, and Wulan Usfi Mafiroh from Biology 2018 under the supervision of Dr. Ardaning Nuriliani, S.Si., M.Kes. This competition was part of the annual KATULISTIWA 14 event, with the theme “Innovative Mindset: Let’s Build Society 5.0 for Indonesia” that aims to express students’ innovations and ideas in order to improve their scientific thinking skills.

This competition was divided into five stages: abstract submission, paper evaluation, announcement of the top ten, video and poster evaluation, and the climax was the presentation of the work in front of the judges. Our team proposed “Decolorization of Textile Dye Waste Based on Enzyme Mediator System by Microalgae” for this competition. This idea was motivated by the fact that many textile industries dispose their waste without proper management, resulting in the environmental pollution and the death of organisms. We proposed the combining ability of microalgae to synthesize enzymes that play a role in decolorization of textile dye waste with biofuel production. We would like to thank everyone who helped us won the 1^st PLACE at the KATULISTIWA 14 event. [US]
