Abstract

Peningkatan pertumbuhan anggrek Dendrobium dapat dilakukan perbanyakan secara kultur in vitro melalui penggunaan media ½ Murashige dan Skoog (MS) dengan penambahan berbagai jenis bahan organik. Penelitian ini bertujuan untuk mengetahui pertumbuhan tunas anggrek Dendrobium dalam media ½ MS dengan penambahan berbagai jenis adenda secara in vitro dan jenis bahan organik mana yang terbaik untuk pertumbuhan anggrek Dendrobium secara in vitro. Tunas dikulturkan dalam media ½ MS dengan tambahan pemberian adenda, ekstrak tomat, bubur pisang, ekstrak jeruk, ekstrak buah naga dan ekstrak jagung manis. Penelitian ini menggunakan rancangan acak kelompok (RAK) dan dilakukan analisis sidik ragam (Anova) dan dilakukan uji lanjut dan uji rerata DMRT (Duncan’s Multiple Range Test) dengan taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa perlakuan penambahan ekstrak jagung manis pada media ½ MS dapat meningkatkan persentase pertumbuhan tunas, tinggi tunas dan pertumbuhan jumlah daun pada tunas anggrek Dendrobium sp. Ekstrak jagung manis merupakan bahan organik tambahan yang terbaik dalam perbanyakan tanaman anggrek Dendrobium sp. secara kultur in vitro.

Abstract

The establishment of the Act must be approved by the President as stated in Article 20 of the 1945 Constitution paragraph (2). Interesting when Indonesia uses a presidential system with the separation of powers. However, in the formation of the Act involving the President. Article 20 paragraph (2) of the 1945 Constitution confirms the necessity of mutual agreement in the discussion and ratification of the Law. However, there are other assertions, namely that in Article 20 paragraph (5) of the 1945 Constitution, even without the President's signature, the Act can still be promulgated within 30 days of the Draft Law being discussed. Things like that can't just happen without a reason. Therefore, the writing of this study will look for the meaning of the agreement between the DPR and the President in the formation of the Law and how the legal politics of Article 20 paragraph (5) of the 1945 Constitution. The writing of this study is focused on researching and searching for the meaning of mutual agreement and focusing on legal politics from Article 20 paragraph 5 of the 1945 Constitution. The research method in this writing is normative juridical. The results of the research can be concluded that the meaning of the joint agreement between the DPR and the President in the establishment of the Law is an agreement in determining the policy in the form of a Law which is a reflection of the principle of checks and balances. Legal politics Article 20 paragraph (5) of the 1945 Constitution is an affirmation of Article 20 paragraph (2) of the 1945 Constitution or can be called an affirmation of collective agreement.

Abstract

One of the techniques that can be applied to overcome seed decline is the invigoration technique using organic materials as priming, namely with young coconut water, bean sprout extract, and aloe vera extract. This study aims to determine the effect of the use of young coconut water, bean sprout extract and aloe vera extract on the viability and vigor of expired cayenne pepper seeds. This study was conducted at the Seed Laboratory of the Agrotechnology Department, Bangka Belitung University. This study used a Completely Randomized Design (CRD) treatment. The treatment given was in the form of organic materials used for priming (Z) with 4 levels of treatment, namely (z0) control, (z1) young coconut water with a concentration of 15%, (z2) bean sprout extract with a concentration of 80%, and (z3) aloe vera extract with a concentration of 50%. Soaking expired cayenne pepper seeds is done for 1 hour. The results of this study indicate that expired cayenne pepper seeds soaked in young coconut water with a concentration of 15% (z1) can increase the parameters of maximum growth potential, seed germination rate, vigor index, plumule length, and dry weight of normal seed sprouts which are better than the control although not significant. The treatment of soaking expired cayenne pepper seeds with organic materials had no significant effect, thought to be due to inaccuracy in the soaking dosage, soaking duration, and abscisic acid content in one of the materials used.
