Abstract

High demand on black rice Oryza sativa L. due to their high antioxydant content and better nutrition than the white rice. On the other hand this high price rice still less interest for the farmet to cultivate it. Therefore, improvement of plant characters was carried out through polyploid induction using the natural anti-mitotic compound bio-catharanthine. The purpose of this study was to test the effectiveness of bio-catharanthine in inducing polyploidy in Cemp ireng black rice. This study used a two-factor completely randomized design (CRD) method with three replications. The treatment factor of bio-catharanthine concentration was 1%, 1.5 %, 2 %, 2 %, 2.5 % and 3 % with the soaking time of 48 hours. The germination rate, ploidy level, stomatal size and density, and antioxidant were measuret to observed the characteristic of the mutan. The results showed that the treatments of 3 % bio-catharanthine enhanced the chromosome number of black rice Cempo ireng. Biocatharantine did not affected the germination rate through the treatments. Out mutants shows alternation on the stomatal size and density. The antioxidant of leaf sample did not changed after the treatment. Bio-catharanthine on high concentration migh be possible to be applied on polyploidy induction in black rice

Abstract

Trichosanthes, one of the largest genera of Cucurbitaceae with in species and sub-species diversity offers a broad study for the systematic and taxonomy and also for the phytochemistry and conservation especially for the local specimen. The aims of this study were to determine the specimen and provided the information of medicinal uses and potency, also the conservation strategy. Determination was conducted by literature and confirmation to the experts, while the medicinal and conservation studied with literature review. The taxonomic investigation through the morphological of specimen collected from Jember, East Java represented Trichosanthes tricuspidata Lour. Medicinal potencies of the species were for threatment of imflamation, worm infection, migrain, and fever. Conservation action via habitat protection, species exploration, seed production, breeding activities were purposed for the flora sustainability.

Abstract

Pembelajaran dengan pendekatan pengembangan ketrampilan merupakan strategi yang sering dipakai dalam pembentukan sikap ilmiah. Prakatikum merupakan metode pembelajaran yang diselenggarakan terhadapa mahasiswa STIKES dr. Soebandi Jember dalam pengenalan dan penggunaan Mikroskop, serta pendalaman materi pembelajaran bentuk dan struktur sel. Pelaksanaan praktikum selama pandemi Covid-19 di Jurusan biologi Universitas Jember dilakukan secara online. Tujuan penulisan artikel ini adalah untuk mengetahui efektifitas pembelajaran online terhadap capaian pembelajaran yang direkam dari kegiatan praktikum. Penelitian dilakukan dengan analisis data capaian pembelajaran dan menguji signifikansi skor rerata nilai laporan praktikum dan membandingkannya dengan tes akhir. Hasil penelitian diketahui bahwa capaian pembelajaran terendah adalah tes akhir yang dipengaruhi oleh beban materi pembelajaran yang diujikan. Pembelajaran berbasis aktivitas dan dilengkapi dengan kecukupan pengetahuan yang dimiliki oleh mahasiswa memberikan hasil optimal dalam penilaian capaian pembelajaran
