Abstract

Generative propagation of orchids is difficult because orchid seeds do not have endosperm for growth and development, so propagation can be done by in vitro. The growth and development of orchids in vitro can be faster and more efficient compared to conventional methods when combined with the addition of growth regulators into the growing medium of in vitro cultures. MS media is a medium that is often used in in vitro propagation because it has the most complete macro and micro nutrients for plant growth and development, but because the price is fairly expensive, the use of 50% MS media can be a solution to this problem.               This study aims to determine the interaction of the use of MS media composition with ZPT BAP, see the effect of MS media composition on the growth and development of orchid buds, and see the effect of ZPT BAP on the growth and development of orchid buds. This research was conducted at the Biotechnology Laboratory, Faculty of Agriculture, Sam Ratulangi University Manado from March to May 2023. This study used a factorial experiment in a completely randomized design (CRD) with 3 replicates consisting of two factors.. The first factor is MS media composition; MS 100% (A1) and MS 50% (A2) and the second factor is BAP concentration; BAP 0.5 ppm (B1), BAP 1.5 ppm (B2), BAP 2 ppm (B3), and BAP 3 ppm (B4). Data were analyzed by ANOVA and if the effect was significant then continued with 5% BNT test. The variables observed were: Shoot height (cm), number of leaves (strands), number of shoots (units), number of roots (units), and wet weight (g). The results showed that there was an interaction between the treatment of MS media composition and growth regulators on the number of shoots, but there was no interaction on the variable shoot height, number of leaves, number of roots, and wet weight of Dendrobium mirbelianum Gaudich orchid shoots. Keywords: Orchid, Dendrobium mirbelianum, MS media, ZPT BAP, In vitro. Abstrak Perbanyakan anggrek secara generatif sulit dilakukan karena biji anggrek tidak memiliki endosperm untuk pertumbuhan dan perkembangannya, maka dari itu dapat dilakukan perbanyakan dengan cara in vitro. Pertumbuhan dan perkembangan anggrek secara in vitro bisa lebih cepat dan efisien dibandingkan dengan cara konvensional jika dikombinasikan dengan penambahan zat pengatur tumbuh ke dalam media tanam kultur in vitro. Media MS adalah media yang sering digunakan dalam perbanyakan in vitro karena memiliki unsur hara makro dan mikro yang paling lengkap untuk pertumbuhan dan perkembangan tanaman, tetapi karena harganya yang terbilang mahal maka penggunaan media MS 50% dapat menjadi solusi terhadap permasalahan tersebut. Penelitian ini bertujuan untuk mengetahui interaksi penggunaan komposisi media MS dengan ZPT BAP dan mendapatkan kombinasi perlakuan yang paling baik terhadap pertumbuhan dan perkembangan tunas anggrek. Penelitian ini dilaksanakan di Laboratorium Bioteknologi, Fakultas Pertanian, Universitas Sam Ratulangi Manado dari bulan Maret sampai Mei 2023. Penelitian ini menggunakan percobaan faktorial dalam Rancangan Acak Lengkap (RAL)  dengan 3 ulangan yang terdiri dari dua faktor. Faktor pertama yaitu komposisi media MS; MS 100% (A1) dan MS 50% (A2) dan faktor kedua konsentrasi BAP; BAP 0,5 ppm (B1), BAP 1,5 ppm (B2), BAP 2 ppm (B3), dan BAP 3 ppm (B4). Data dianalisis dengan ANOVA dan jika berpengaruh nyata maka dilanjutkan dengan uji BNT 5 %. Variabel yang diamati adalah: Tinggi tunas (cm), jumlah daun (helai), jumlah tunas (unit), jumlah akar (unit), dan berat basah (g). Hasil penelitian menunjukkan bahwa terdapat interaksi antara perlakuan komposisi media MS dan zat pengatur tumbuh terhadap jumlah tunas, tetapi tidak terdapat interaksi pada variabel tinggi tunas, jumlah daun, jumlah akar, dan berat basah tunas anggrek Dendrobium mirbelianum Gaudich.

Abstract

Subterranean termite Coptotermes sp. is one of the important pests that pose a threat to agriculture. Coconut shell liquid smoke is the result of a pyrolysis distillation process. The content of compounds in liquid smoke includes phenolic compounds, carboxylic acids, and carbonyls. The objective of the study was to determine the effective concentration of coconut shell liquid smoke to control the subterranean termite Coptotermes sp. This study used a completely randomized design (CRD) with 5 treatments, 1 treatment (control), and 4 replications. Subterranean termites used were 300 subterranean termites, each treatment filled with 15 termites (12 workers and 3 soldiers). The research data was calculated to obtain the total mortality percentage of Coptotermes sp. on the last observation. Data were analyzed using Sidik Ragam (ANOVA). If the concentration of the treatment shows a significant effect, then proceed with the 5% LSD (Least Significant Difference) test. Control of the Coptotermes sp. subterranean termite. with coconut shell liquid smoke grade 3 effect on the mortality of Coptotermes sp. subterranean termites. Treatment with a concentration of 1 ml of coconut shell liquid smoke is effective and economical to be used as an organic insecticide among other treatments in controlling Coptotermes sp. subterranean termites. Keywords: Control, Mortality, Rayap Subteran, Coconut Shell Liquid Smoke Abstrak Rayap bawah tanah Coptotermes sp. merupakan salah satu hama penting yang menjadi ancaman dalam bidang pertanian. Asap cair tempurung kelapa merupakan hasil proses destilasi pirolisis. Kandungan senyawa pada asap cair antara lain senyawa fenolik, asam karboksilat dan karbonil. Tujuan penelitian adalah untuk mengetahui konsentrasi asap cair tempurung kelapa yang efektif untuk mengendalikan rayap tanah Coptotermes sp. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan, 1 perlakuan (kontrol) dan 4 ulangan. Rayap tanah yang digunakan sebanyak 300 ekor rayap, masing-masing perlakuan diisi 15 ekor rayap (12 pekerja dan 3 prajurit). Data penelitian dihitung untuk memperoleh persentase kematian total Coptotermes sp. pada pengamatan terakhir. Data dianalisis menggunakan Sidik Ragam (ANOVA). Apabila konsentrasi perlakuan menunjukkan pengaruh nyata maka dilanjutkan dengan uji LSD (Beda Nyata Terkecil) 5%. Pengendalian Coptotermes sp. rayap bawah tanah. dengan asap cair tempurung kelapa grade 3 berpengaruh terhadap mortalitas Coptotermes sp. rayap bawah tanah. Perlakuan dengan konsentrasi 1 ml asap cair tempurung kelapa efektif dan ekonomis untuk digunakan sebagai insektisida organik diantara perlakuan lain dalam mengendalikan Coptotermes sp. rayap bawah tanah.

Abstract

The tissue culture technique can be the best method of choice because it is fast in propagation and has a relatively short time. This research was conducted using a completely randomized design, with 4 treatments, namely: P0. MS Media 100%, P1. MS Media 90% + 10% Coconut Water, P2. MS Media 80% + 20 Coconut Water, P3. MS Media 70% + 30% Coconut Water. Each treatment was repeated 10 times to obtain 40 experimental units and in each experimental unit/bottle, there were 2 shoot explants. The results of the study that the substitution of Coconut Water in MS Media had a significant effect on plant height parameters but had no significant effect on parameters of number of leaves, number of roots, number of branches, and dry weight of potato plantlets. The best use of coconut water as a substitute for MS media for the growth of potato plantlets is at a concentration of 30%. because it did not differ from the control (100% MS media), especially the parameters of the number of leaves, number of roots, number of branches, and dry tissue of potato plantlets. Keywords: Potato Seeds, MS Media, Coconut water Abstrak Teknik kultur jaringan dapat menjadi pilihan metode terbaik karena cepat dalam perbanyakannya dan memiliki waktu yang relatif singkat. Penelitian ini dilakukan dengan menggunakan rancangan acak lengkap, dengan 4 perlakuan yaitu: P0. MS Media 100%, P1. MS Media 90% + 10% Air Kelapa, P2. MS Media 80% + 20 Air Kelapa, P3. MS Media 70% + 30% Air Kelapa. Setiap perlakuan diulang sebanyak 10 kali sehingga diperoleh 40 satuan percobaan dan pada setiap satuan percobaan/botol terdapat 2 eksplan pucuk. Hasil penelitian bahwa substitusi Air Kelapa pada Media MS berpengaruh nyata terhadap parameter tinggi tanaman namun tidak berpengaruh nyata terhadap parameter jumlah daun, jumlah akar, jumlah cabang, dan berat kering planlet kentang. Pemanfaatan air kelapa sebagai pengganti media MS untuk pertumbuhan planlet kentang yang terbaik adalah pada konsentrasi 30%. karena tidak berbeda dengan kontrol (media 100% MS) terutama pada parameter jumlah daun, jumlah akar, jumlah cabang, dan jaringan kering planlet kentang.
