Abstract

Sampah organik merupakan bahan biodegradable yang mudah terdegradasi oleh dekomposer. pembuangan sampah organik menghasilkan bau yang tidak sedap. Kecamatan Gamping terletak di Kabupaten Sleman, Yogyakarta. Seiring bertambahnya jumlah penduduk, volume sampah meningkat pesat. Jika tidak ada kesadaran pengelolaan sampah oleh masyarakat, penumpukan sampah akan menjadi masalah lingkungan. Tujuan program ini yaitu memberikan penyuluhan dan pelatihan bagi peserta tentang pengelolaan sampah rumah tangga, khususnya sampah organik. Evaluasi pengetahuan peserta dilakukan dengan menyebarkan kuesioner pada awal dan akhir pelatihan. Peserta program ini menunjukkan antusiasme yang tinggi. Program ini memberikan efek positif yang signifikan pada seluruh peserta. Hal ini terlihat dari adanya peningkatan pengetahuan dan keterampilan peserta dalam mengelola sampah organik menjadi pupuk cair dan kompos. Harapannya, melalui program ini, peserta dapat berperan sebagai agen edukasi, mendidik anggota keluarga dan orang lain di sekitar untuk turut serta dalam upaya pengelolaan sampah organik di rumah tangga.

Abstract

One part of the avocado (Persea americana Mill.) that is often unused and considered waste is the avocado seed. Avocado seeds have the potential to be made into an extract because they contain antioxidant compounds. The aim of this research was to determine the highest antioxidant activity, total phenolic and total flavonoid content in methanol and chloroform extracts, and to determine the relationship between total phenolic and total flavonoid content on the IC50values of methanol and chloroform extracts. Antioxidant activity was tested using the DPPH method. Data analysis used the classic assumption test, independent sample t-test, and Pearson correlation test. The results showed that the highest IC50 was found in the chloroform extract at 349.28 ± 137.29 µg/mL DW. The highest phenolic content was found in the methanol extract at 2,419.51 ± 389.54 mgGAE/g DW. The highest total flavonoid content was found in the chloroform extract at 232.13 ± 54.32 mgQE/g DW. Based on the Pearson correlation test, the total flavonoid content had a correlation (0.028<0.05) with the IC50 value of methanol and chloroform extracts of avocado seeds, while the total phenolic content had no correlation (0.749>0.05) with the IC50 value of methanol and chloroform extracts of avocado seeds

Abstract

As the COVID-19 pandemic comes to an end, education has returned to normal with in-person learning. The good practices in online learning conducted during the pandemic can be maintained to support practical activities, for example, using a virtual laboratory. The limitations of laboratory facilities and the skills of educators and laboratory staff in developing practical materials have made Biology practicals minimal and monotonous. Based on discussions with partners, there is a main problem that needs to be addressed through this program, which is the limited laboratory facilities in terms of tools and materials, resulting in minimal implementation of Biology practical activities in schools. The objective of this community service is to enhance the knowledge, skills, and empowerment of Biology teachers at Muhammadiyah high schools in Yogyakarta City in conducting practicals using virtual labs. This community service method is carried out by training on Biology practical learning online using virtual labs. This program is conducted in several sessions, each lasting 200 minutes, from June to October. Each session consists of a pre-test, material delivery, Q&A discussions, and a post-test. It can be concluded that the community service activities ran smoothly and provided benefits in the form of increased knowledge and skills of participants in Biology practical learning using virtual labs.

Abstract

Kembang leson sering dimanfaatkan sebagai aromaterapi pada saat pemulihan bagi pasien karena dipercaya dapat menghilangkan rasa lesu. Komposisi kembang leson sangat beragam, terdiri dari beraneka bunga dan rimpang, serta belum ada kajian mendalam terkait dengan kandungan senyawa terutama minyak atsiri pada kembang leson. Penelitian ini bertujuan untuk mengetahui kandungan minyak atsiri yang terdapat pada kembang leson. Pada penelitian ini dilakukan ekstraksi minyak atsiri dengan metode destilasi Stahl, minyak atsiri yang diperoleh dianalisis kualitatif dan kuantitatif. Analisis kualitatif minyak atsiri meliputi pengamatan organoleptis; sementara analisis kuantitatif minyak atsiri dilakukan dengan kromatograf gas-spektra massa (KG-SM). Minyak atsiri yang diperoleh memiliki bentuk cair, jernih, berwarna kuning kecokelatan, bau aromatis. Rendaman minyak atsiri yang diperoleh sebesar 0,75% (v/b). Analisis KG-SM diperoleh 50 komponen penyusun minyak atsiri, lima komponen minyak atsiri yang memiliki luas area tertinggi yaitu camphene kadarnya sebanyak 1,29% , benzene metil cymene 4,93%, camphor 4,75%, cyclohexanemethanol 7,56% dan curdione 4,83%.

Abstract

Household organic waste management in densely populated areas such as Tegalrejo, Yogyakarta, poses a significant challenge that impacts both environmental quality and public health. This community service program aimed to enhance the knowledge and skills of local residents—particularly members of the PRA Tegalrejo women's group—in utilizing Black Soldier Fly (BSF) larvae, or maggots, as biological agents for organic waste decomposition. The training was conducted through educational sessions, live demonstrations on maggot utilization, and interactive discussions. The results showed a 14.73% increase in participants’ understanding, based on pretest and posttest scores. Participants not only gained knowledge about the decomposition process using maggots, but also recognized the potential of maggot farming as a source of animal feed and local economic opportunity. This program demonstrates that hands-on, eco-friendly education can effectively encourage community participation in waste management while simultaneously strengthening environmental resilience and household socio-economic sustainability.
