Abstract

The 21st century is the digital age, so learning is expected to take advantage of technology. Teachers have not utilized technology as much as possible so learning in the classroom is not optimal. This study aims to develop a web-based e-module teaching material on the human reproductive system for high school/MA class XI students. The research and development model uses ADDIE. The research subjects consisted of 1 media expert, one material expert, two biology teachers, and 30 students. Data collection methods consist of observation, interviews, and questionnaires. Data analysis used descriptive qualitative and quantitative descriptive. The results showed that the assessment score of media experts was 3.82 (Very Valid); the score of material experts was 3.50 (Valid); the score of the biology teacher was 3.91 (Very Valid), and a student score of 3.46 (Valid). Therefore, it can conclude that the web-based e-module on the human reproductive system material is suitable for biology learning. Web-based e-modules can help class XI students to study independently anytime and anywhere and to understand material on the human reproductive system.

Abstract

The accumulation of rubbish at temporary waste storage locations has become a common concern for us. The organic waste in the rubbish pile usually causes a very strong pungent odor. In fact, if organic waste is managed from every house/location that produces it, it will very significantly reduce both the volume of rubbish piles and the pungent stench. Therefore, it is necessary to instill awareness in every member of society about the importance of managing waste and specifically organic waste which can be degraded by various types of organisms. One of the organisms that can be used to process this organic waste is maggot, which is the larva of the black soldier fly (BSF). Apart from being an organic waste processing agent, maggots can also be used as a feed supplement for chickens and fish. In this way, maggot cultivation can have a dual function for community members who are motivated to manage organic waste independently. Through Lecturer Activities Off Campus (DLK) activities this year, the community in Umbulmartani Village, Ngemplak District, Sleman was given training on Maggot Cultivation to be used as an organic waste processor on a household scale and can also be used to improve the family economy if maggot cultivation is carried out managed seriously. The final activity is evaluation. The program results show the success of the process as indicated by: a. Attendance of participants reaches 100%, b. Increasing knowledge and skills in cultivating maggots for processing family organic waste, c. The results of the participant satisfaction questionnaire showed that participant satisfaction in all aspects was good and very good.

Abstract

Masalah sampah merupakan isu besar, terutama dengan ditutupnya Tempat Pemrosesan Akhir (TPA) Piyungan dalam menampung sampah dari Kabupaten Sleman, Bantul, dan Kota Yogyakarta. Di Padukuhan Nayan, sampah organik dan anorganik dibuang di pekarangan dan di sungai atau dibakar oleh sebagian warga sehingga menimbulkan pencemaran lingkungan dan mengganggu Kesehatan. Masyarakat belum mempunyai pengetahuan mengelola sampah organic menjadi produk yang bermanfaat dan ramah lingkungan, padahal sampah organik berpotensi dimanfaatkan menjadi produk bermanfaat dan bisa bernilai ekonomi. Maka dari itu kegiatan ini bertujuan untuk  mengedukasi dan melatih masyarakat dalam mengelola sampah organik menjadi ekoenzim yang bermanfaat dan ramah lingkungan. Kegiatan dilakukan melalui sosialisasi, pemberian materi, praktek pembuatan dan pemanfaatan ekoenzim, monitoring dan evaluasi kegiatan kepada 45 peserta yang terdiri dari warga pedukuhan Nayan. Pelatihan dilakukan pada 7 September 2024, dengan pemantauan setiap  bulan sekali selama 3 bulan. Peserta menunjukkan antusiasme yang tinggi terhadap materi dan praktek pembuatan ekoenzim yang dapat dilihat dari penilaian evaluasi oleh peserta dengan hasil sangat baik. Setelah pelatihan, mereka berhasil mengaplikasikan teknik pembuatan ekoenzim dalam mengelola sampah organik rumah tangga. Ekoenzim yang dihasilkan digunakan untuk pupuk dan pembersih lantai. Kegiatan ini juga menunjukkan peningkatan kesadaran tentang pentingnya pengelolaan sampah secara ramah lingkungan, yang mendukung tujuan SDGs ke-12 terkait produksi dan konsumsi yang bertanggung jawab. Pelatihan pembuatan ekoenzim berhasil meningkatkan keterampilan masyarakat dalam pengelolaan sampah organik dan berkontribusi pada pengelolaan lingkungan sekitar menuju pembangunan berkelanjutan.

Abstract

The intensive application of organophosphate pesticides containing profenofos as the active compound may lead to soil contamination and the emergence of pesticide-tolerant bacterial strains with potential for bioremediation. Comprehensive identification and characterization of these bacteria are crucial to support sustainable agricultural and environmental management practices. The aim of the study is to analyze the characteristics and identify indigenous bacteria tolerant to profenofos pesticide in Sleman agricultural land, DIY. This study is qualitative research using an exploratory-descriptive. Isolation was carried out by dilution to a level of 10-7 followed by a spread plate on Mineral Salt Medium (MSM) which was given with 100 ppm profenofos pesticide. Bacterial isolates were characterized and then identified using profile matching with reference genera. Based on the results of the study, it is found that 10 bacterial isolates tolerant to organophosphate pesticide with the active ingredient profenofos that have a similarity index of ≥70%. Based on the reference bacteria, 5 different genera are obtained, namely Paracoccus (D3, D8), Micrococcus (D5, D6, D9), Enterococcus (D2, D10), Arthrobacter (D1, D4), and Neisseria (D7). The bacterial isolates obtained have different characteristics. The characteristics of these bacteria are gram positive and negative bacteria with round, irregular, and rhizoid shapes. Their margins are lobate, curled, entire, undulate, and ciliate. Their elevations are umbonate, raised, and flat. The color of the bacteria is white to light orange, with various physiological test results.

Abstract

The amount of mask waste has increased significantly due to the COVID-19 pandemic. Mask waste can be found everywhere, likewise in Wana Tirta Mangrove. Its existence in the mangrove ecosystem, making mask waste, has the potential for cellulolytic bacteria. The purpose of this study is to determine the cellulase enzyme activity, characteristics, and genus of purified cellulolytic bacteria found in mask waste from Wana Tirta Mangrove. The method used in this study was qualitative research. The samples for this research were bacterial isolates from mask waste, which had previously been isolated from the Wana Tirta Mangrove. Samples were grown on CMC media to determine isolates that were included in cellulolytic bacteria. The cellulase activity of cellulolytic bacteria was tested qualitatively and quantitatively. Morphological, physiological and biochemical tests were carried out to obtain phenetic characters which were then used as the basis for determining the genus of cellulolytic bacteria. The results showed that 10 isolates were cellulolytic bacteria. The highest activity of cellulase enzyme qualitatively was produced by isolate 72 with a value of 0.466 mm, while the highest activity of cellulase enzyme quantitatively was produced by isolate 84 with a value of 0.931 U/ml. The dendrogram result showed 4 genera of cellulolytic bacteria, including Pseudomonas, Alcaligenes, Cellulomonas, and Aeromonas.
