The growing medium is an important factor for plant growth and development. Many growing media are used for orchids, but their availability is limited and some are prohibitively expensive. Therefore, alternative growing media need to be studied. This study was conducted to investigate the potency of some alternative growing media for growing two Dendrobium genotypes, D. sylvanum and D. nindii x D. stratiotes, at the post-acclimatization stage. Five growing media were used in this experiment, namely tree fern fibers, coconut fibers, sphagnum moss, asplenium root, and calliandra humus.

Climate change significantly impacts sweet potato production because of the high potential for drought conditions. Understanding the regional impacts of climate change on the irrigation interval is important for effective water resource management. This study aims at determining the influence of the irrigation interval on the drought tolerance responses of two new sweet potato varieties from Universitas Padjadjaran. The experiment was arranged in a randomized block design (RBD) with two factors. The first factor was two varieties of sweet potato i.e. Awachy-1 (Orange-Fleshed) and Biang (Purple-Fleshed); and the second factor was the irrigation interval (1, 3, 5 and 7 days). This research was conducted in a screen house of Ciparanje experimental field station, Universitas Padjadjaran Jatinangor. Experimental results showed no interaction between the irrigation intervals and the varieties on the sweet potato's yield components and nutritional content. Biang provided the most optimal result regarding the number of tubers and dry mass, despite being watered once every three days. Biang also produced a higher number of tubers, shorter sweet potato length and higher dry weight than Awachy-1 in every irrigation interval. Biang also showed a higher value for nutritional content than Awachy 1 on total soluble solids, sugar and carbohydrate content. The optimal water usage to store the root yield of Biang and Awachy-1 is one to three days of irrigation intervals on the sweet potato’s tuber diameter and the plant's dry weight. However, the irrigation interval that most significantly improved the weight of the tuber was one day, while the increased nutritional content of the tuber was three days. Biang and Awachy-1 cultivars could survive under drought conditions, although some yield components had decreased. These results suggested that the varieties or watering interval affected sweet potato growth and yield components.

Pengembangan anggrek lokal merupakan salah satu kegiatan yang memiliki prospek menjanjikan khususnya di daerah Jatiangor yang merupakan kawasan lingkungan pendidikan, wisata serta banyaknya perkantoran dan perumahan yang memerluk Kegiatan ini dilaksanakan di wilayah Desa Cileles Kecamatan Jatinangor Kabupaten Sumedang. Masih banyaknya lahan pekarangan yang belum dimanfaatkan secara optimal merupakan peluang untuk pengembangan anggrek. Permasalahan masih terbatasnya pengetahuan dan minat warga untuk membudidayakan anggrek. Anggrek kultivar Dian dan Zahra 27 merupakan anggrek jenis baru yang belum banyak dikenal oleh masyarakat setempat. Oleh karena itu, perlu adanya salah satu kegiatan untuk mensosialisasikan dan mendiseminasikan kedua jenis anggrek ini khususnya di kawasan Jatinangor sebagai langkah awal pengembangan anggrek secara komersial. Tujuan kegiatan pengabdian kepada masyarakat ini adalah meningkatkan wawasan serta minat masyarakat Desa Cileles dalam pengembangan anggrek yang memiliki nilai ekonomis tinggi dengan pemanfaatan lahan pekarangan. Metode yang digunakan adalah: memberikan penyuluhan termasuk pelatihan mengenai materi prospek pengembangan anggrek, teknik persilangan anggrek, teknik produksi bibit anggrek secara kultur jaringan, teknik budidaya anggrek dan teknik pemasaran anggrek. Hasil kegiatan menunjukkan bahwa peserta terutama para remaja putri dan ibu-ibu PKK berminat untuk mengembangkan tanaman anggrek pada skala komersial baik dalam bentuk bibit maupun tanaman dewasa
