Abstract

This study aimed to determine the effect and identify the optimal sterilization pattern for suppressing contaminant growth in the in vitro culture of Sidikalang Arabica coffee (Coffea arabica L.) leaf explants. The experiment was conducted using a completely randomized design (CRD) with five treatment levels and 15 replications. Data were analyzed using the Kruskal Wallis test, and if significant differences were found, the Mann Whitney test was applied at a 5% significance level. The results showed that sterilization patterns significantly affected the time to contamination onset, the percentage of contaminated explants, the percentage of browning explants, and the percentage of explants forming callus. However, no significant effect was observed on the time of callus initiation. Sterilization pattern 5 was identified as the most optimal in suppressing contamination, with the lowest contamination percentage (6,6%), browning (6,6%), and the highest callus formation (93,3%). This pattern involved washing with detergent; soaking in Agrept (30 minutes) and Benlate (30 minutes); followed by sterilization in a laminar airflow cabinet (LAFC) using Tween 20 (20 minutes), graded Bayclin at 10%, 20%, and 30% (for 20, 15, and 5 minutes, respectively), 70% alcohol (20 seconds), and ascorbic acid (20 minutes).

Abstract

Penelitian ini menelusuri makna falsafah kepemimpinan dalam budaya Minangkabau dan relevansinya bagi praktik kepemimpinan di Indonesia masa kini. Metode yang digunakan ialah pendekatan kualitatif dengan dukungan kuantitatif korelasional, melalui wawancara mendalam dan penyebaran angket kepada informan terpilih secara purposive. Analisis data dilakukan menggunakan uji korelasi Pearson untuk melihat hubungan antara tingkat pemahaman terhadap nilai-nilai kepemimpinan adat dan sikap penerapannya dalam konteks nasional. Hasil penelitian memperlihatkan bahwa pemahaman responden terhadap nilai-nilai kepemimpinan Minangkabau tergolong sangat tinggi (rata-rata skor 4,87 dari 5), sedangkan nilai korelasi r = 0,97 menunjukkan hubungan positif yang kuat antara kedua variabel tersebut. Temuan ini membuktikan bahwa semakin mendalam pemahaman seseorang terhadap nilai-nilai seperti adat basandi syarak, syarak basandi Kitabullah, bajanjang naik batanggo turun, serta duduak samo randah tagak samo tinggi, semakin bijak pula sikap kepemimpinannya. Nilai-nilai falsafah Minangkabau ini terbukti tetap relevan sebagai pedoman moral dan etis untuk membentuk karakter pemimpin yang adil, berintegritas, serta demokratis di Indonesia

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

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

This study evaluates the effects of NaOCl concentration and immersion time on contamination levels and viability of in vitro mangosteen seed explants, aiming to identify the optimal sterilization protocol. Conducted at YAHDI Tissue Culture Laboratory, Medan, Indonesia, a Randomized Complete Block Design tested three treatment combinations: (1) 15% and 10% NaOCl for 5 minutes, (2) 20% and 15% NaOCl for 15 minutes, and (3) 30% and 20% NaOCl for 25 minutes. After immersion, explants were rinsed three times with sterile distilled water. Observations spanned 12 MST, with data analyzed using ANOVA and Games-Howell post hoc tests; contamination sources were qualitatively described. Results showed the first combination had the lowest effectiveness, the second was better but suboptimal, while the third significantly delayed contamination and yielded the highest explant survival rate of 86.1%. The third treatment also prolonged the contamination-free period compared to others. Fungal and bacterial contaminants were predominant, highlighting the need for effective disinfectants against both. These findings indicate that the third combination is a promising sterilization protocol for mangosteen seed explants, especially for hard endocarp tissues prone to contamination.

 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
