Abstract

Using leaf explants, this research aimed at identifying the type of growth response that can be created and the optimal mix of media for the growth of Cattleya sp orchid. This was an experimental investigation employing the RAL method (completely randomized design) with a combination of 2.4-D (0;1; 2; 3 ppm) and Kinetin  (0;0.3;0.6 ppm) repeated three times. According to the results of this study, the growth regulators 2.4-D and kinetin  were unable to promote the development of all explants. Explants transferred to media containing polyvinylpyrrolidone (PVP) to prevent browning after 12 weeks of observation. Then the results of the study also found the emergence of shoots in the treatment P0 (control), P2 (2,4-D 0 + Kinetin  0.6 ppm), P8 (2,4-D 2 + Kinetin  0.6) and P11 (2.4- D 3 + K 0.6 ppm) in the 3rd week of observation, the appearance of callus at P5 (2.4-D 1 + Kinetin  0.6 ppm) in the 4th week of observation

Abstract

This study aims to determine the effect of plant growth regulators and seed cutting patterns on the induction of mangosteen shoot growth. The research was conducted at the YAHDI Tissue Culture Laboratory in Medan, North Sumatra, Indonesia, in 20245. The method used in this study was a Completely Randomized Design (CRD) with two factors: BAP concentration and seed cutting pattern. The data collected were analyzed using statistical analysis of variance (ANOVA) with Duncan's Multiple Range Test (DMRT) at a 5% significance level using SPSS 26. The results of the study show that the interaction between BAP concentration and seed cutting pattern significantly affected the time of shoot emergence, the number of leaves, and the shoot height. The best shoot emergence time was obtained with a BAP treatment of 4 mg/L using whole seed explants, which occurred at 1 MST (Month After Sowing). A BAP concentration of 2 mg/L with whole seed explants produced the highest number of leaves, with 8 leaves. The highest number of shoots was obtained from explants planted in a medium with 6 mg/L BAP, which resulted in 5.67 shoots. Whole seeds planted in a medium with 0 mg/L BAP produced the tallest plants, measuring 8.9 cm. The combination of BAP concentration and seed cutting pattern did not significantly affect the number of roots.

Abstract

Orchids are ornamental plants that have high aesthetic value and beauty. Many human activities use this plant, including weddings, Christmas, New Year and birthdays. Orchid propagation can be done conventionally, but it requires a large area of land and takes a long time to grow. However, it can also be multiplied using tissue culture. Plant tissue culture techniques have better prospects than conventional propagation because tissue culture can produce large numbers of new plants without being influenced by time or season. This research aims to determine the effect of IAA and leaf order on shoot growth of Cattleya sp orchid plants. This type of research is experimental research with a Factorial Completely Randomized Design (CRD) with 12 treatments and 3 replications. There are 2 factors in this study, namely factor I PGR IAA (0, 0.5 mg/l, 1 mg/l, and 1.5 mg/l) and factor II Leaf order (1st leaf, 2nd leaf, and 3rd leaf). This research is a quantitative descriptive study with the parameters of the time of shoot emergence and using 2-way Statistics with Analysis of Variance (ANOVA) with the parameters of number of shoots, number of leaves (strands), and plantlet height. From the research results, it was found that the administration of IAA (Indole Acetic Acid) and the order of the leaves did not have a real effect on the number of shoots, number of leaves (strands) and plantlet height. However, the best treatment is the I0.5D2 treatment (IAA 0.5 mg/l and 2nd leaf).

Abstract

Penggunaan pupuk organik, baik dalam bentuk padat maupun cair, mampu meningkatkan kualitas tanaman secara keseluruhan. Tanaman yang dipupuk dengan organik cenderung menghasilkan panen yang lebih melimpah, dengan bobot yang lebih berat, kesegaran yang lebih lama, serta cita rasa yang lebih lezat dibandingkan dengan tanaman yang dipupuk dengan bahan kimia. Kandungan mineral, zat-zat penting, dan hormon pertumbuhan tanaman yang terdapat dalam pupuk organik cair turut berkontribusi dalam memaksimalkan potensi pertumbuhan tanaman. Lebih lanjut, dibandingkan dengan pupuk kimia, pupuk organik, khususnya dalam bentuk cair, lebih efektif dalam merangsang pertumbuhan vegetatif tanaman dan meningkatkan kapasitas tanah dalam menyerap serta menahan unsur hara yang dibutuhkan tanaman. Penelitian ini secara mendalam mengeksplorasi bagaimana variasi konsentrasi pupuk organik cair yang berasal dari bekas limbah beras dapat memberikan pengaruh yang berbeda-beda bagi proses penumbuhan bayam. Melalui pendekatan kuantitatif yang teliti, penelitian eksperimental ini dirancang untuk mengumpulkan data empiris yang dapat diuji secara statistik. Dengan menggunakan rancangan acak lengkap, penelitian ini membandingkan pertumbuhan tanaman bayam yang diberi perlakuan pupuk dengan dua tingkat konsentrasi yang berbeda, yaitu 80% dan 100%. Setelah dilakukan pengamatan lapangan selama 28 hari di Dusun II, Gang Buntu, Kecamatan Tanjung Morawa, data pertumbuhan tanaman bayam yang diperoleh kemudian diolah secara komprehensif menggunakan aplikasi perangkat lunak Excel. Analisis deskriptif yang dilakukan bertujuan untuk memberikan gambaran yang jelas mengenai pola pertumbuhan tanaman sebagai respons terhadap variasi konsentrasi pupuk organik cair yang diberikan. Penelitian ini memberikan bukti empiris mengenai potensi pemanfaatan limbah rumah tangga, yaitu air cucian beras, sebagai sumber nutrisi tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk organik cair dengan konsentrasi 100% memberikan pengaruh yang signifikan terhadap pertumbuhan tanaman bayam. Namun demikian, penelitian ini juga menyarankan perlunya penelitian lebih lanjut untuk mengoptimalkan penggunaan pupuk organik cair dalam sistem budidaya tanaman.
