The research was motivated by a lack of enthusiasm for learning for students because the delivery of course material which is considered boring by conventional delivery methods without any variation. Based on the reason in this study developed a computer-based digital learning media for Urban Geography course material which is a type of development research. The result of this research is that the media is easy to use learning and increased student motivation to learn which is expressed by 97.67% of the students.

Morinda citrifolia L. leaves extract (MCLE) has been used as a medical material because of its antibacterial properties. Hydrogels synthesized from polyvinyl alcohol (PVA) are known to be applicable as delivery media for antibacterial substances. This article reports using the freeze-thaw method to use PVA hydrogel as an encapsulation medium for MCLE. PVA/MCLE hydrogel was synthesized in several combinations, namely 10:0, 10:1, 10:2, 10:3, 10:4, and 10:5. The test results showed the conductivity and pH values of the precursor solution increased as the extract fraction increased, but decreased in the viscosity. The hydrogel showed a morphology with increased pore size when the extract fraction in the hydrogel increased. FTIR characterization confirmed that the extract had been successfully loaded into the hydrogel. The swelling degree test of the hydrogels showed an increase for samples 10:1 to 10:3 and a decrease for samples 10:4 to 10:5. Increasing the extract fraction then resulted in a decrease in the gel fraction of the hydrogel. The antibacterial activity test confirmed that the antibacterial activity in the extract remained present after being encapsulated in the hydrogel. Thus, the addition of MCLE affects the performance of the hydrogels to be applied in the medical field.

Daerah Lembang merupakan salah satu desa dengan potensi pertanian, khususnya tanaman sayuran. Namun, keterbatasan sumber daya air dan praktik penyiraman konvensional menjadi kendala utama dalam peningkatan produktivitas pertanian di desa tersebut. Melalui program Pengabdian kepada Masyarakat (PKM) yang didanai Kementerian, tim PKM Universitas Halim Sanusi melaksanakan penerapan teknologi irigasi tetes sebagai solusi alternatif untuk mengatasi permasalahan kekurangan air sekaligus meningkatkan efisiensi penggunaan tenaga kerja. Kegiatan dilaksanakan di dua tempat, yaitu di lahan petani di Desa Gudang Kahuripan dan Kelurahan Lembang. Kegiatan meliputi sosialisasi, perancangan, pembangunan instalasi irigasi tetes, pendampingan, dan evaluasi bersama petani. Hasil menunjukkan bahwa irigasi tetes mampu mengurangi penggunaan air, menurunkan beban tenaga kerja dalam penyiraman, serta meningkatkan keterampilan masyarakat dalam penerapan teknologi tepat guna. Respon masyarakat sangat positif karena teknologi ini dinilai praktis, efisien, dan mendukung keberlanjutan pertanian di Daerah Lembang.
