Improving the Quality of the Local Chicken Eggs and Marketing for Livestock Farmers in Condong Catur Village, Sleman, Yogyakarta

HeadlineNews ReleaseStudent ActivitiesWaste Management Monday, 4 December 2023

[MBKM-PkM] The Independent Learning Independent Campus (MBKM) Community Service Program team from the Faculty of Biology, UGM, led by Prof. Dr. Endah Retnaningrum, M.Eng., along with four students Avila Kusuma W, Daimeera Anja, Shanaz Dhiya’ul Haq, and Syahidina has been conducting socialization and mentoring sessions with “Shobaru” livestock farmers in Condong Catur Village, Sleman, Yogyakarta, from October to November 2023.


The mentoring aimed to improve the quality of the local chicken eggs through the provision of fermented feed. The quality of these eggs is enhanced compared to those from non-fermented feed. The local chicken eggs have a richer taste and a stronger yolk color due to their high β-carotene content. This improvement is attributed to the higher nutritional content and better digestibility of fermented feed for the poultry. Moreover, providing fermented feed increases the animals’ appetite while reducing the odor from their waste. Additionally, fermented feed serves as a cost-effective alternative to commercial feed, which tends to be more expensive. The team also conducted socialization and mentoring on branding and online marketing of the local chicken eggs through social media platforms, including guidance on managing social media accounts. Packaging the local chicken eggs with branding has expanded their market reach, allowing consumers to locate and contact the local chicken egg farmers, thereby increasing the product’s visibility.

Through the MBKM Community Service activities by the Faculty of Biology, UGM, the “Shobaru” livestock farmers have seen improvements in both the quality of their egg products and their marketing strategies. This has led to sustained economic prosperity for the community while also contributing to environmental preservation.

Faculty of Biology UGM Received Visit from Kemantren Jetis to learn about organic waste processing

HeadlineNews ReleaseWaste Management Monday, 13 November 2023

Organic waste processing is a method of managing waste derived from organic materials, such as food scraps, leaves, and other organic matter that can naturally decompose. The goal of organic waste processing is to reduce negative environmental impacts and utilize the potential energy or products that can be generated from organic waste. Managing waste is a positive activity to mitigate various negative impacts caused by waste, both on the environment and human health. Therefore, it is important to implement sustainable waste management practices, such as recycling, reducing plastic usage, and educating the community about the importance of environmental cleanliness. Additionally, governments, communities, and the private sector need to collaborate to create sustainable and environmentally friendly solutions. This aligns with the Sustainable Development Goals (SDGs), specifically Goal 12, which emphasizes sustainable waste management as a form of responsibility for consumption and production.


The Faculty of Biology at UGM once again received a visit from Kemantren Jetis, Yogyakarta, to learn about organic waste management using Bio Ferti 2023. “This activity aims to support the growth of family awareness in improving the quality of environmental sustainability, especially in Kemantren Jetis and in the Special Region of Yogyakarta in general,” said Mr. Joko Sularno, Chairman of the Kemantren Jetis Waste Bank Forum, in his remarks.

The event was summarized in the Strengthening Workshop for the Cadres of the Kemantren Jetis Waste Bank on Friday, November 10, 2023, at the Tropical Biology Auditorium and the Organic Waste Processing Area of the Faculty of Biology at UGM and was attended by 40 people, including cadres from the Kemantren Jetis Waste Bank and Waste Bank Groups at the RW level in Kemantren Jetis. The workshop was divided into two sessions: the first session included presentations and an introduction to organic waste processing at the Faculty of Biology at UGM, while the second session involved observing the practical process of organic waste processing by the UGM Faculty of Biology Waste Management Task Force.

Mrs. Zaenab, Acting Head of the Kemakmuran Office of Kemantren Jetis, expressed gratitude to Mr. Soenarwan Hery Poerwanto, S.Si., M.Kes., Chairman of the Waste Management Task Force at the Faculty of Biology at UGM, and to the leaders of the Faculty of Biology at UGM for granting permission and welcoming the group to learn about organic waste management using Bio Ferti 2023.

Development of Future PHB Plastic-Producing Organisms

HeadlineResearch and PublicationWaste Management Friday, 10 November 2023

[MBKM]- Plastic has become an inseparable part of modern human life, from clothing, food packaging, household tools, to building materials. Despite its various benefits, plastic poses a significant threat to the sustainability of life on Earth, with over 10 million tons of plastic waste released into the environment and oceans annually. Numerous efforts are ongoing to address this issue, one of which involves seeking alternatives to conventional plastic that are more eco-friendly and sustainable. One potential substitute is PHB or polyhydroxybutyrate, a biopolymer naturally found in various types of microorganisms. It’s believed to become the primary polymer for future plastic materials, replacing conventional petroleum-based plastic due to its biobased, biosynthesized, and biodegradable. Recognizing this challenge and opportunity, three students from the Faculty of Biology UGM, Azizah Tyas Nugrahanty, Bagas Alfian Dwiaryanda, and Lucia Arum Sekar Meysari, embarked on the Independent Learning- Independent Campus (MBKM), focusing on developing effective and efficient PHB-producing organisms by utilizing genetic transformation technology.


This MBKM program was conducted under the guidance of Ganies Riza Aristya, S.Si., M.Sc., Ph.D., from the Faculty of Biology, UGM, in collaboration with Raden Afif Pranaya Jati, S.P., M.Sc., from the Indonesian Bioinformatics Institute (INBIO-Indonesia). Throughout the research, the students engaged in various activities ranging from dry lab experiments to wet lab experiments. The study began with discussions regarding the selection of vectors and host microorganisms to be used. Subsequently, they designed plasmid vectors for genetic transformation and created primers to serve as markers for positive colony identification through colony PCR. The research then progressed to the wet lab phase at the Genetics and Breeding Laboratory at Faculty of Biology UGM, involving the preparation of competent cells, genetic transformation using the electroporation method, colony PCR followed by electrophoresis to confirm positive colonies carrying the target gene. As of now, the team has successfully incorporated synthetic genes constructed within the plasmid into bacterial cells as candidates for naturally producing PHB microorganisms.

PkM-MBKM Faculty of Biology UGM 2023: Community Empowerment of Kepuh Kulon RT 001, Wirokerten, Banguntapan, Bantul through Usefully Wide Waste Management (Phase II: Production of Processed Waste and Waste Utilisation)

Community ServiceHeadlineWaste Management Thursday, 9 November 2023

The team of Pengabdian Kepada Masyarakat – Merdeka Belajar Kampus Merdeka (PkM-MBKM) Faculty of Biology UGM 2023 that chaired by Rina Sri Kasiamdari, Ph.D. and involved two students, namely Galuh Kirana Mahadewi and Laila Uswatun Chasanah, carried out again a series of Community Service activities in Kepuh Kulon RT 001, Wirokerten, Banguntapan, Bantul. This activity is a continuity of the PkM-MBKM activities that have been carried out previously from February to June 2023.

The first activity of this PkM MBKM phase II was held on Sunday, October 8th 2023 from 09.00 to 11.00 WIB at the house of the neighborhood head of Kepuh Kulon RT 001, Mr. Zamzuri, and attended by 18 people of Kepuh Kulon RT 001. The activity on that day was packaging the compost and eco enzymes that had been made previously. First of all, Galuh and Laila gave a short explanation and demonstration about how to harvest and package the compost and eco enzyme. The compost was harvested by dried it for a while. After that, the compost could be packaged in a customized plastic ziplock. Unlike the compost, eco enzymes must be filtered between the fruits that are used and the water and then packaged in 250 mL bottles as much as 60 bottles. The compost that have been made is used for plant fertilization, while the eco enzyme is used for washing dishes, cleaning floors, repelling pests, cleaning vegetables and fruit from pests, and cleaning glass or glass surfaces. The compost and eco enzymes that are already packed and labeled are given to the Head of Wirokerten village and the Head of Hamlet. Hopefully, the skills of the women residents of Kepuh Kulon RT 001 in making compost and eco enzymes can become a reference in managing daily household waste, so that they can reduce the accumulation of waste and can make household waste more useful.

The second activity was about utilising used cooking oil (UCO) that become household waste into aromatherapy candles. It was held on Sunday, October 29th 2023 from 09.00 to 12.30 WIB at the house of the neighborhood head of RT 001 Kepuh Kulon, Mr. Zamzuri, and attended by 18 people of Kepuh Kulon RT 001. In this activity, the used cooking oil was made into solid aromatherapy candles and liquid aromatherapy candles. Tools and materials that used for making solid aromatherapy candles were used candle wick, wood holder, tea filter, plastic basin, pan, measuring cup, stove, cement pot, saucepan, cutting board, knife, spoon, used cooking oil, stearic acid, crayon, and essential oil, whereas the tools and materials that used for making liquid aromatherapy candles were glass cup, tissue paper, the cover of pudding cup, five different food colouring, water, used cooking oil, and essential oil. During the practice of making aromatherapy candles, we produced 100 solid aromatherapy candles and 25 liquid aromatherapy candles. All of them were distributed and could be used by the residents of Kepuh Kulon RT 001. Hopefully, the utilisation of UCO into aromatherapy candle could be one of the solution for reducing oil waste that can cause an environmental pollution and also could be a micro/small/medium enterprises (MSMEs) business idea for Kepuh Kulon RT 001 residents. The aromatherapy candles also distributed to the Head of the Hamlet, and the Head of Wirokerten Village. It is hoped that this PkM-MBKM program can provide new knowledge for Kepuh Kulon RT 001 residents in processing and utilizing household waste into more useful products.

Students and Lecturers from the Faculty of Biology Share Knowledge about Natural Dyes and Organic Waste Processing with the Members of PKK RT01 Blotan Hamlet, Wedomartani, Sleman

HeadlineNews ReleaseWaste Management Tuesday, 7 November 2023

In connection with the continuation of the Community Service Program – the Independent Learning Independent Campus (MBKM) 2023, the Faculty of Biology Universitas Gadjah Mada in Blotan hamlet, led by Prof. Dr. Kumala Dewi MSc.St along with students, Alfina Damayanti ( and Estherina Claudya Manurung, conducted an extension activity on natural food and Fabric Dyes as well as Organic waste processing using stacked bucket at The Blotan village hall on Thursday, October 2023 from 3.30 PM to 5.00 PM. The activity was attended by the head of PKK RT 01 along with 12 members.


The material was delivered by Prof. Dr. Kumala Dewi MSc.St. She explained the advantages and disadvantages of using synthetic dyes compared to natural dyes. The use of natural dyes, whether for food and beverages or for batik fabric coloring, supports the Sustainable Development Goals (SDGs), especially goal number 2, which aims to end hunger, achieve food security, improve nutrition, and promote sustainable agriculture. Natural dyes introduced in this session included butterfly pea flowers (Clitorea ternatea L) for blue color and roselle (Hibiscus sabdariffa L) which provides red color for food and beverages. Additionally, there are other types of plants that can be used for food coloring, such as turmeric, pandan leaves, and black rice. In addition to providing natural color, the use of infusions from butterfly pea flowers, roselle petals, and black rice can also support health as they contain beneficial compounds like anthocyanins and vitamin C, which act as antioxidants. By planting butterfly pea flowers, roselle, or other beneficial plants, the environment can also be enhanced. Regarding fabric dyeing, Prof. Kumala Dewi MSc.St explained that the leaves of the indigo plant (Indigofera tinctoria L), which belongs to the legume family, can be processed to produce Indican dye, which imparts a blue color to fabric. The use of natural dyes for fabric can also reduce water pollution, which often occurs around batik industries that use synthetic dyes. Planting Indigofera is easy, and this plant can be beneficial in improving soil fertility.

In addition to the explanation about natural dyes, the process of household organic waste processing to create liquid fertilizer using stacked buckets was also presented. This was done in an effort to support the resolution of the waste problem, which has been a trending issue recently due to household waste disposal sites being full. Proper separation of household waste needs to be carried out diligently by every household member. Organic waste can be collected in stacked buckets, and with the help of Hermetia illucens flies that lay eggs in the waste, maggots can consume the waste and produce liquid fertilizer as well as residual solid waste. Both can be used for vegetable fertilizer, whether planted in polybags or in the field. From previous analyses, liquid fertilizer from organic waste processing with stacked buckets and the assistance of black soldier fly maggots contains hormones and amino acids that are beneficial for promoting plant growth. In this counseling event, small agar-agar snacks were also served, colored with natural blue dye (from butterfly pea flowers) and red dye (from roselle). Additionally, five sets of stacked buckets were provided for practical use in household organic waste processing. The participants were very enthusiastic in responding to the counseling session, with several questions discussed. Those who received the stacked buckets will report on their usage through videos, as well as the liquid fertilizer products produced. From this counseling activity for the PKK mothers in Blotan hamlet, it is hoped that the role of women in supporting food security for families and environmental sustainability can be established and sustained.

Presenting Integration Innovation of Activated Sludge Method in the WasteWater Treatment Facility (IPAL) at TPST Piyungan, Student of Faculty Biology Win 1st Place in National Essay Competition

AchivementsHeadlineNews ReleaseWaste Management Wednesday, 1 November 2023

Biology students at Gadjah Mada University (S1) made another achievement at the national level by winning 1st place in the National Essay Competition. This achievement was achieved by Rima Arvisya Natania Putri, Reny Ras Ninta Br Tarigan, dan Gafra Favian Ratmoro, a student at the Faculty of Biology class of 2022 under guidance of Dr. Miftahul Ilmi . This national-level essay competition was organized by Department of Biology Universitas Islam Negeri Walisongo Student Executive Board with the Theme “Optimizing the Role of Smart, Proactive, and Innovative Young Generations in Facing the 5.0 Revolution as an Effort to Realize Indonesia Emas 2045”. The competition opened on 1 July 2023 and the winners were announced on October 24, 2023.


In this competition the team took the subtheme Ecotechnology with the title “ Integration of Activated Sludge Method in the WasteWater Treatment Facility (IPAL) at TPST Piyungan, Yogyakarta”. The team discusses water as a source of life for all living organisms on earth. Unfortunately, the water around Piyungan Wastewater Treatment Facility are contaminated by Leachate from suboptimal processing. Based on Research By Kartikasari et al. (2020), shown that after undergoing aeration treatment, the quality of leachate in the Piyungan Landfill still does not meet the established quality standards. The research results indicate the content of the leachate as follows: TSS 235 mg/L, BOD 241 mg/L, COD 3511 mg/L, TN 700 mg/L, Hg 0.1015 mg/L, Cd 0.035 mg/L, Cr 0.021 mg/L. The standard limits are TSS 100 mg/L, BOD 150 mg/L, COD 300 mg/L, TN 60 mg/L, Hg 0.005 mg/L, Cd 0.1 mg/L, Cr 0.1 mg/L. This comparison of data indicates the suboptimal performance of the Wastewater Treatment Plant (WWTP) applied in the Piyungan Landfill. These contents can be highly dangerous when in direct contact with living organisms.

Given this issue, there is a need for the development of the activated sludge method to treat leachate more efficiently and effectively, with the aim of removing organic contaminants and hazardous chemicals contained within it. The innovation brought by this team involves the development of the activated sludge method with the optimization of land use, utilization of flocs, provision of biomass storage tanks, and the use of PAC as a clarifying agent. Thus, it is hoped that this innovation will be able to create a Wastewater Treatment Facility that meets the standards, thereby restoring the quality of water to a better state and enhancing the self-sufficiency of the community in support of the realization of Indonesia Emas 2045.
