Saponins are one of the secondary metabolites found in Shallot (Allium cepa L.), particularly in the roots. Microclimate differences in the cultivation area are thought to have a significant impact on the production of secondary metabolites, such as saponins. This research aimed to observe the saponins content in the root of shallot plants cultivated in marginal agricultural land and their antimicrobial activity against bacteria (Ralstonia solanacearum) and fungus (Fusarium oxysporum). This research was observational research with a random sampling method. The samples were collected from the shallot plantation with two different cultivation conditions. Two varieties of ‘Bima' and 'Tiron' cultivated by farmers in sandy coastal land Samas, Bantul were used. The plants were harvested at 1, 1.5, and 2 months after planting, respectively. The crude saponins extract was used to test antimicrobial activity. Shallot plants cultivated in marginal coastal sandy land produced higher saponins accumulated in their roots. The saponins production increased along with the maturity of shallot plants, both cultivated in marginal coastal sandy land and regular paddy field. The saponins extracted from the roots of shallots cultivated in both marginal and regular land showed higher antimicrobial activity than antifungal activity. Saponin merupakan salah satu metabolit sekunder yang terdapat pada bawang merah (Allium cepa L.), terutama pada bagian akar. Perbedaan iklim mikro pada lahan budidaya diduga akan berpengaruh terhadap produksi metabolit sekunder termasuk saponin. Tujuan penelitian ini adalah untuk mengetahui kandungan saponin pada bagian akar tanaman bawang merah yang dibudidayakan di lahan pertanian marginal serta aktivitas antimikrobanya terhadap bakteri (Ralstonia solanacearum) dan jamur (Fusarium oxysporum). Penelitian ini merupakan penelitian observasi dengan metode pengambilan sampel secara acak. Sampel berasal dari perkebunan bawang merah dengan dua lahan budidaya yang berbeda. Digunakan dua varietas yaitu 'Bima' dan 'Tiron' yang dibudidayakan oleh petani di daerah pantai Samas,kabupaten Bantul. Bahan tanaman dipanen pada tiga waktu berbeda, yaitu 1 bulan, 1,5 bulan dan 2 bulan berturut-turut setelah tanam. Ekstrak kasar saponin digunakan untuk menguji aktivitas antimikrobanya. Tanaman bawang merah yang dibudidayakan di lahan marginal pasir pantai menghasilkan saponin yang lebih tinggi yang terakumulasi pada akarnya. Produksi saponin semakin meningkat seiring dengan umur tanaman bawang merah, baik yang dibudidayakan di lahan marginal pasir pantai maupun di lahan sawah biasa. Saponin yang diekstraksi dari akar bawang merah yang dibudidayakan di lahan marginal dan lahan biasa menunjukkan aktivitas antimikroba yang lebih tinggi daripada aktivitas antijamurnya.

This study aims to determine the differences in variations of crude papain enzyme concentration and optimal fermentation time on the microbiological quality of skipjack tuna (Katsuwonus pelamis L.) fish sauce. This research is an experimental study with two variables: 2 different enzyme concentrations (5% and 10%) and 3 different periods (3, 7 and 11 days). The microbiological tests include the Escherichia coli contamination test, total microbial test, and total lactic acid bacteria test. Physical tests include water content tests, pH tests, and organoleptic tests. The results showed that the enzyme concentration and fermentation time affected the microbiological quality of skipjack tuna sauce. The sample with an enzyme concentration of 10% and a fermentation time of 11 days was the best sample of skipjack tuna fish sauce because no E. coli bacteria were found (negative), the total BAL test result was 8.2 x 103 cfu/mL, and the TPC result was 7.1 x 103 cfu/mL which meets SNI standards for Fish Sauce No. 01-4271-1996. This sample also had the best organoleptic test results: a non-fishy aroma, savory taste, and dark brown color. Based on the pH test, samples with enzyme concentrations of 5% and 10% and a fermentation time of 3 days have a pH value that meets the requirements, namely 5.88 (pH requirement 5-6). The results of the water content test showed that all samples did not meet the standards.

Biological material, one of which is the sensory system, whose objects are difficult to approach directly, requires more sophisticated learning media. This is because the sensory system learning process still uses 2D-based learning media which is difficult to display biological objects in real terms. Teachers and students need media that can visualize material well and can be accessed flexibly via smartphone. Technology AR, with its characteristics of being able to display objects in more detail in 3D and being able to be used on smartphones, could be a solution. This research aims to develop AR on human sensory system material. This research uses the ADDIE (analysis, design, development, implementation, and evaluation). Data collection was carried out through expert validation and implementation of student responses. The material expert validation results were 98.25% and the media expert validation results were 89.25% (very good category). The teacher assessment results were 96.75%, and student responses were 83.5% (very good category). Based on these results, it is known that the AR media developed is suitable for use in learning sensory system material in biology learning

Pendidikan di Indonesia merupakan hak bagi semua anak bangsa, baik yang ada di tanah Indonesia maupun yang sedang berjuang di negara lain. Para pejuang devisa selain bekerja mencari uang mereka juga secara tidak langsung belajar skill dan pengetahuan baru. Hal ini dapat dimanfaatkan untuk mengikuti program rekognisi pembelajaran lampau (RPL). RPL adalah program pemerintah dengan tujuan memberikan kesempatan kepada seluruh penduduknya mendapatkan pengakuan formal yang berkaitan dengan keahliannya. Universitas Negeri Yogyakarta (UNY) merupakan salah satu perguruan tinggi yang dipercaya menyelenggarakan program tersebut. Untuk menyebarluaskan informasi mengenai program RPL kepada diaspora Indonesia, perlu dilakukan program sosialisasi program RPL tersebut terutama pada diaspora Indonesia di Préfecture Yamaguhi. Kegiatan ini bekerjasama dengan PPI Yamaguchi dan dilaksanakan secara hybrid (offline dan online). Terdapat 79 peserta yang hadir secara hybrid, namun hanya 22 peserta yang mengisi angket kepuasan. Secara umum peserta puas dengan kegiatan ini dan tertarik untuk dapat mengikuti program RPL. Sebagian kecil merasa bingung dan masih akan berfikir untuk mengikuti program ini. Kegiatan seperti ini perlu dilaksanakan tidak hanya di Jepang namun di beberapa negara lainnya untuk menngkatkan jumlah mahasiswa RPL di UNY.
