“…The Synthetic sex pheromone used in our study was effective in capturing S. litura adults in the Indonesian population [19]. The effectiveness of azadirachtin to control larvae of L. indicata assigned S. litura has been reported [30,31] According to Mordue and Nisbet [32] active compound of neem affects several insect physiological activities such as feeding activity, reproductive ability, moulting process, chitin-forming, etc.…”

Pests are one of the limiting factors in increasing soybean production. Pest control carried out by farmers using pesticides is feared to threaten the sustainability of soybean production in Indonesia. This study aimed to identify the effect of different pest management systems and various soybean varieties on pest population dynamics, abundance and diversity of natural enemies, plant damage, and soybean production. A split plot design with three replications was applied, where the main plot was pest management systems i.e. (1) control (which received neither chemicals nor integrated pest management), (2) chemical control, and (3) integrated pest management, and the sub-plot was soybean varieties i.e. (1) Anjasmoro, (2) Demas 1, and (3) Dering 1. Results indicated that variety affects pest diversity and abundance, however, it affected leaf damage, pod damage, and production. The pest management systems influenced the diversity and abundance of pests and natural enemies, plant damage, and production. Interaction between variety and pest management system affected plant damage. We conclude that the use of resistant varieties combined with integrated pest management could reduce plant damage, maintain the natural enemy population, and optimize soybean production.

Plak adalah pembentukan komunitas bakteri yang terorganisir pada permukaan gigi yang berupa lapisan tipis tidak berwarna. Pseudomonas aeruginosa adalah salah satu bakteri yang sangat berperan pada pembentukan plak. Metabolit sekunder yang terkandung dalam tanaman Kalanchoe tomentosa dapat digunakan sebagai antibakteri. Tahapan penelitian diawali dengan maserasi menggunakan pelarut n-heksan dan diklorometana. Ekstrak diklorometana dipisahkan menggunakan Kromatografi Cair Vakum (KCV) dengan n-heksana dan etil asetat sebagai pelarut bergradien selanjutnya direkristalisasi dengan n-heksan, hasil rekristalisasi didapatkan isolat 1. Isolat 1 dikarakterisasi dengan spektroskopi infra-red (IR), ultraviolet (UV) dan nuclear magnetic resonance hydrogen (1H NMR) serta dibandingkan dengan literatur. Isolat 1 diketahui merupakan stigmast-5-en-3ꞵ-ol atau ꞵ-sitosterol. Pada ekstrak diklorometana dan senyawa ꞵ-sitosterol kemudian ditentukan aktivitas antibakteri secara mikrodilusi didapatkan hasil bahwa ekstrak diklorometana dan senyawa ꞵ-sitosterol bukan hanya menunjukan sifat bakteriostatik tetapi juga bakterisid kuat terhadap bakteri Pseudomonas aeruginosadengan nilai Konsentrasi Hambat Minimum (KHM) <100 µg/mL.Steroid Compounds from Cocor Bebek (Kalanchoe tomentosa) as Antibacterial Pseudomonas aeruginosa. Plaque is a thin, colorless layer that adheres tightly to the surface of the teeth and contains a collection of bacteria. One of the bacteria that can form dental plaque is Porphyromonas aeruginosa. Kalanchoe tomentosa contain secondary metabolite which can be used as antibacterial. Stages of the study begin with maceration using n-hexane and dichloromethane. Dichloromethane extract was separated using Vacuum Liquid Chromatography (KCV) using n-hexane and ethyl acetate solvents and then recrystallized with n-hexane, the recrystallization results were obtained by isolate 1. Isolate 1 was marked by IR spectroscopy, and 1HNMR and compared with literature. Isolate 1 is known as stigmast-5-en-3ꞵ-ol or ꞵ-sitosterol. In dichloromethane extracts and ꞵ-sitosterol is determined by microdilution by microdilution. The results showed that dichloromethane extract and ꞵ-sitosterol compound not only showed strong bacteriostatic but also bacterisid activity against P. aeruginosa with Minimum Inhibiroty Concentration (MIC) <100 μg / mL.

“…the best concentration of Azadirachta indica seed extract 50 EC at a concentration of 2% with a mortality of 76.67% and decreases feeding activity, larvae weight, and lengthening the development time of S. litura. The administration of K. pinnata 50 EC extract was slightly toxic and insignificant feed consumption, weight, and duration of development of larvae compared to controls (Paramita et al, 2018). Research using the factorial RAL method consists of 2 factors, namely the application of neem leaf extract and castor leaf.…”

The growth regulators of gibberellin and cytokinins are found in banana hump extract, while natural pesticides are found in the neem leaf extract. These two active ingredients can condition the growth and yield of chilies. There have not been any publications on the use of banana hump extracts and neem leaves to increase the growth and production of chili plants. The writing of this research article aims to explore the diversity of Indonesia's biological resources, among others, sword stalk banana hump extract and neem leaves which can stimulate the growth and yield of red chilies. Data analysis used a randomized block design with two variables and 3 repetitions. The first treatment used banana hump extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five percent, and the second treatment used neem leaf extract which consisted of four percentage levels, namely zero, fifteen, thirty, and forty-five, percent. A total of 600 grams of banana hump granules and neem leaves plus 1 liter of methanol, concentrated to a volume of 250 ml were used in this study. The results of the research showed that giving banana hump extract and neem leaves was able to stimulate the growth of leaf area so that it had an impact on increasing photosynthesis and plant metabolism. Fruit weight cannot be stimulated because, during the study, there was a long dry season, so there was a water deficit which was a limiting factor in the production of fruit formation.
