Abstract

Orchid mycorrhiza is a type of fungus that is able to associate well with orchid plants. Orchids require fungal hyphae infection at every phase of their growth and development. Mycorrhizal fungi provide the organic and organic nutrients needed by orchid planting. Meanwhile, orchid plants are suppliers because the results of photosynthesis of orchid plants are distributed in the body of fungi as an energy source. Given the importance of the prospect of mycorrhizal utilization for orchids, it is necessary to continue to develop studies on identification. The purpose of this study is to isolate, identify and characterize mycorrhiza in Dendrobium nobile orchids. The method used was with a descriptive design on the identified orchids, samples in the form of Dendrobium nobile orchid roots, the media used was PDA media, transverse and longitudinal root cut types.  The way it works includes sample preparation, media preparation, fungal isolation, fungal colony purification,

Abstract

Way Umpu River, located in Way Kanan Regency, Lampung Province, is widely used by the local community and the waste products are ultimately disposed of into the river. This can cause a decrease in river water quality which can cause changes in the balance of the ecosystem, both biotic and abiotic. One of the organisms that can be used as a bioindicator is macrozoobenthos. This research aims to determine the diversity of macrozoobenthos as a bioindicator of water pollution quality. The method used was a survey method and sampling using Ekmen Grab at 6 sampling stations. Samples were taken 3 times in the left, middle and right bank areas of the river. Apart from that, water analysis was carried out in the form of physical parameters (temperature and TSS) and chemical parameters (pH, DO, COD, BOD). The data was then analyzed using the Diversity Index. The research results found 14 types of macrozoobenthos consisting of 5 phylum, namely Arthopoda, Mollusca, Porifera, Ciliophora, and Annelida. From the results of the analysis of the macrozoobenthos diversity index at station IV, it has a value of 0.56 ind/m2, which states that the location is heavily polluted. Physical and chemical factors show a significant correlation with macrozoobenthos diversity.

Abstract

Pendahuluan: Kemajuan biologi molekuler membuka peluang besar dalam riset genomik, berdampak luas pada bidang kesehatan, pertanian, dan lingkungan. Diperlukan peningkatan keterampilan sivitas akademika dalam pengoperasian alat laboratorium biomolekuler. Metode: Pelatihan dilakukan melalui pendekatan teori dan praktik langsung (hands-on training), dengan evaluasi menggunakan pre-test dan post-test untuk mengukur peningkatan pemahaman peserta. Hasil: Terdapat peningkatan signifikan pada skor post-test, terutama dalam penerapan alat untuk riset. Peserta menunjukkan peningkatan pemahaman, khususnya dalam aspek teknis penggunaan alat. Kesimpulan: Pelatihan ini efektif dalam meningkatkan kompetensi laboratorium peserta. Direkomendasikan pelatihan lanjutan dan pendampingan rutin untuk memperkuat keterampilan riset biologi molekuler secara berkelanjutan.
