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.

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.

This study aims to determine the larval population and pest attack of S. frugiperda on two varieties and eight lines of hybrid maize implemented in Talawaan Village. It is hoped that from this study information on larval populations and pest attacks of S. frugiperda on two varieties and eight lines of hybrid maize implemented in Talawaan Village will be obtained. This study used a randomized block design with 10 treatments, consisting of two varieties and eight lines, each treatment was repeated 3 times, so that 30 experimental units were obtained. As treatments were two maize varieties, namely ADV 777 (A) and JH 37 (J) and eight lines namely HLN 01 (B), HLN 02 (C), HLN 03 (D), HLN 04 (E), HLN 05 ( F), HLN 06 (G), HLN 07 (H), HLN 08 (I). Observations were made at intervals of 1 week starting at 15 ADP, 22 ADP, 29 ADP and 36 ADP.  The things that were observed were attack symptoms, larval populations and the percentage of S. frugiperda in the treatments being tested. The results showed that the highest average population of S. frugiperda larvae was found in the 36 ADP observations, namely treatment I (HLN 08) namely 165.33 individuals and the lowest in treatment A (ADV 777) of 18.33 individuals. The highest percentage of attacks was observed at 36 ADP, namely treatment I (HLN 08) of 46.00% and the lowest in treatment A (ADV 777) of 11.00%.

This research was conducted in Tababo Village, Belang District, Southeast Minahasa Regency. The research time was three months from July to September 2021. This research used a quantitative method where the three organic wastes were mixed with the contents of the rumen of cows and water into the biodigester and fermented for one month. Data collection was done by measuring the height of the biodigester cylinder, conducting a fuel test, measuring the temperature, and weighing the weight of the biogas. Data from measurement and testing results were compared with data on a mixture of fermented cow rumen contents and water. The results of measurements of the addition of biodigester height showed that the highest organic waste on the first day was 5 cm with an average weekly biogas productivity of 24.1 cm. Whereas in the rumen contents of cows, methane gas burned on the seventh day and the best burning was on the fourteenth day. Biogas in cow rumen contents burns faster than biogas in organic waste. The color of the resulting fire is bluish. The weight of the biogas produced is 1.8 kilograms.
