Abstract

 Penelitian ini bertujuan untuk Untuk mendapatkan teknik sterilisasi yang terbaik untuk eksplan batang anggrek Cattleya sp. muda. Penelitian ini dilakukan di Laboratorium Kultur Jaringan YAHDI Perum Pelabuhan Jl. Lambung No. 8 Tanah 600 Medan Marelan. Rancangan penelitian yang digunakan dalam penelitian ini adalah metode eksperimental laboratorium dalam mencobakan beberapa teknik sterilisasi. Untuk mengetahui teknik sterilisasi yang tepat, penelitian ini menggunakan eksplan lapang anggrek Cattleya Sp. dengan jenis pendekatan deskriptif kuantitatif. Data dianalisis dan ditabulasi menggunakan parameter penelitian hari terkontaminasi, persentase eksplan yang terkontaminasi, persentase eksplan browning, persentase eksplan yang membengkak, persentase eksplan yang membentuk bakal tunas dan persentase eksplan hidup. Hasil penelitian ini menunjukkan bahwa terdapat 2 teknik sterilisasi yang optimal dalam sterilisasi eksplan lapang Anggrek Cattleya Sp. yaitu teknik sterilisasi 2 dan 4. Teknik sterilisasi 2 menggunakan zat sterilan deterjen, akuades steril, Tween-20, benomil 50%, agrimicin, NaOCl 15% 10% dan alcohol 70% kemudian teknik sterilisasi 4 dengan zat sterilan Clorox 1,05%, HgCl 0,02% dan akuades steril merupakan teknik sterilisasi yang tersebut. Hal ini ditunjukkan dengan rendahnya tingkat kontaminasi eksplan dan tampaknya spot-spot hijau pada eksplan dimana eksplan akan mengalami pertumbuhan tunas. Faktor-faktor yang menyebabkan kontaminasi pada eksplan Anggrek Cattleya Sp. adalah kurangnya kehati-hatian praktikan pada saat melakukan sterilisasi eksplan lapang, kontaminasi endogenus yang tinggi dan penggunaan zat steril yang kurang tepat

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana rebranding yang dilakukan UMKM KRIKEN untuk menjangkau retail modern sebagai strategi komunikasi pemasaran. Metode penelitian yang digunakan dalam penelitian ini adalah kualitatif dengan pendekatan deskriptif. Informan di dalam penelitian ini adalah pemilik UMKM KRIKEN. Teknik pengempulan data dilakukan melalui tiga tahap, yaitu observasi non-partisipan, wawancara mendalam dan studi dokumentasi. Sedangkan, teknik analisis data dilakukan dengan menerapkan model Miles and Huberman, yaitu reduksi dan penyajian data serta penarikan kesimpulan. Hasil penelitian menunjukkan bahwa rebranding sebagai strategi komunikasi pemasaran perlu diperhatikan dan diterapkan oleh pemilik UMKM untuk menembus pasar retail modern. Produk yang memiliki informasi yang lengkap seperti tanggal kadaluarsa, komposisi, berat produk dan kandungan nilai gizi, menjadi salah satu diantara poin penting yang diperhatikan pihak retail modern. Selain itu, rebranding pada logo yang memanfaatkan ilustrasi animasi dianggap menjadi daya tarik dan keunikan tersendiri bagi produk. Begitu pula dengan kemasan, penting untuk menggunakan packaging yang lebih mencolok seperti standing pouch dengan pemilihan warna yang terang dan cerah, agar produk terlihat lebih memanjakan mata dan bisa diletakkan di rak-rak retail modern, dimana produk serupa yang telah lebih dahulu terkenal di pasaran.

Abstract

This study aims to examine the indigenous knowledge of the traditional oil formulation of the Karo ethnic using an ethnoscience approach. The ethnoscience approach is a learning method that reconstructs indigenous science into scientific knowledge. This research is a descriptive qualitative study. Data was collected through a literature review, observations, and interviews with the Karo ethnic residing in Medan. The results show that the Paeam formulation involves various types of spices, leaves, and roots. There are 4 plant species used as ingredients in the preparation of param, they belong to 8 different plant families.The family with the most species is Zingiberaceae, with 6 species. Based on the results obtained, the study further explores indigenous science using an ethnoscience approach. The reconstruction of indigenous knowledge into scientific knowledge in the processing of Paraml can be observed in the following stages: 1) The collection of spices and, 2) The Process of Making Param. The integration of param processing into Junior High School science learning can be seen in the topics of classification of living things (grade VII), element, compound, and mixture (grade VIII), and temperature, heat, and expansion (grade VII). It can be concluded that the processing of param is integrated with science learning at the junior high school.

Abstract

This study aims to obtain a good concentration of IBA and plantain and is suitable for root induction in Dendrobium sp. The benefit of this study is to provide information about the successful root induction of orchid plantlets Dendrobium sp. In vitro culture and creating formulations using IBA hormones and organic plantain ingredients in in vitro culture media optimally. This research has been carried out at the YAHDI Plant Tissue Culture Laboratory. Rooting orchids Dendrobium sp. In vitro using MS basic media which was added with IBA (Indole 3 Butyric Acid) 0 ppm, 2 ppm, 4 ppm, and 6 ppm, and added with plantain pulp with levels of 0 g/l, 100 g/l. and 200 g/l. This study was a factorial experiment with 2 factors compiled based on a 4 x 3 Complete Random Design (RAL) with 12 treatment combinations. The data obtained was analyzed for variance analysis (ANOVA). If there are results that have a real effect, it is followed by the DMRT (Duncan Multiple Range Test) test at the level of 5%. (1) The results of the study showed that the treatment of the variables of the number of roots, plant height, and root length was influenced by IBA. (2) The treatment of the variables of the number of buds, the number of leaves, the number of roots, the height of the plant, and the length of the roots is influenced by plantains. (3) The treatment of the variables on the number of roots, root length, and leaf width were influenced by the interaction of IBA and banana pulp.
