Euodia suaveolens is one of the plants that ancient people in Indonesia used due to its manifold benefits. Earlier research on this plant was mostly done on its potency as a mosquito repellent. This present study aims to determine the phytochemical and antibacterial analyses of the essential oils (EOs) extracted from the leaves of E. suaveolens. The EOs of the leaves of E. suaveolens were extracted by steam distillation method and were analyzed phytochemically utilizing the GC-MS technique to determine the chemical constituents. The chemical components were tested on four pathogenic bacteria Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis utilizing the diffusion agar method. The results showed that the main compounds extracted from the EOs were delta curcumene, evodone, globulol, limonene, linalool, longipinenepoxide, menthofuran, and p-mentha-1,8-diene. The antibacterial analysis of these compounds showed potential activities to inhibit the growth of four pathogenic bacteria tested, but the inhibition zones formed were still lower compared to commercial antibiotic kanamycin. E. suaveolens EOs exhibited diameter of zone of inhibition as follows 2.03 plus minus 0.22, 0.50 plus minus 0.49, 1.38 plus minus 0.10, 1.40 plus minus 0.27 cm to E. coli, P. aeruginosa, S. aureus, and S. epidermidis while kanamycin showed 3.43 plus minus 0.08, 3.25 plus minus 0.08, 3.38 plus minus 0.12, and 3.18 plus minus 0.24 cm respectively. These results recommend that the main compounds extracted from the EOs of the leaves of E. suaveolens be explored further to determine their potencies as new antibiotic medications.

Paroki Santa Theresia Lisieux (STL) Boro terletak pada area pengembangan pariwisata sehingga berpotensi menjadi desa wisata dengan amenitas khas berupa jahe emprit. Produksi jahe pada area ini memiliki keterbatasan kuantitas, kontinuitas, dan kualitas karena minimnya pengetahuan dan ketrampilan petani dalam penanaman dan pemeliharaan tanaman serta pengolahan rimpang jahe menjadi produk jadi. Fakultas Teknobiologi, Universitas Atma Jaya Yogyakarta memberikan pelatihan dan pendampingan untuk memperbaiki pengetahuan dan ketrampilan petani jahe di area Paroki STL Boro. Pelatihan dan pendampingan dibagi menjadi tujuh kali pertemuan yang terdiri dari sosialisasi dan evaluasi pengetahuan dalam bentuk kuesioner, dilanjutkan dengan pelatihan tentang prapanen, panen, pascapanen primer dan sekunder, serta yang terakhir adalah evaluasi berupa diskusi dan kuesioner. Topik pertemuan pascapanen sekunder terdiri dari pembuatan produk kesehatan (serbuk jahe instan) dan produk kosmetik (lulur jahe). Hasil analisis data kuesioner secara semikuantitatif menunjukkan terjadi peningkatan pengetahuan petani sebesar 75% antara sebelum dan sesudah pelatihan. Dengan adanya pelatihan, petani di Paroki STL Boro mampu menghasilkan produk jahe instan yang telah dipasarkan secara terbatas.

Abstract "Teratai Salju" is a symbiotic community of bacteria and yeast. One of the fermentation results of "snow lotus" was alcohol that is useful as a solvent such as cosmetics, disinfectants, and fuels. This research aims to determine the genus of microorganisms and the maximum ethanol content produced by "teratai salju" using palm sugar and sucrose variations 15, 45 and 85 grams in 250 ml water with 5 repetitions. Stages of research including growth and maintenance of "snow lotus", observation of colonies morphology, yeast staining, negative staining, Gram staining, dry weight measurement, total acid number, pH measurement, and ethanol content measurement. Data analysis was performed by Analysis of variance (ANOVA) followed by a duncan multiple range test with a 95% confidence level with SPSS 15.0. This research was conducted with a Completely Randomized Design (CRD). The results obtained show that ethanol content of "teratai salju" optimized at the addition of 85 gram sucrose at 0,22-0,86%. Key Words : Ethanol, Fermentation, Sucrose Variation, “Teratai salju”.

This community service program aimed to strengthen the human resource capacity of tourism village administrators of Bojong Tourism Village through the development of a growth mindset integrated with a benchmarking visit to Pentingsari Tourism Village, Sleman. The program, conducted on July 26, 2025, involved 19 prospective tourism village administrators, consisting of 12 men and 7 women. The benchmark was designed through four main stages: (1) outbound activities; (2) a sharing session with Pentingsari managers on strategies for tourism village development and the formulation of a unique selling point; (3) participation in local attractions, namely the gamelan-playing experience and Merapi honey coffee educational tour; and (4) filling of a growth mindset questionnaire before the activities. The results indicated increased awareness among participants regarding the importance of continuous learning, creativity, collaboration, spontaneous leadership, and communication skills in tourism village management. These findings highlight that integrating growth mindset and benchmarking can serve as an effective strategy to strengthen human resource capacity, foster innovation, and promote sustainability in the development of Bojong Tourism Village. Keywords: growth mindset, benchmarking, tourism village, integration
