Selasih (Ocimum basilicum L.) memiliki kandungan minyak atsiri yang dapat digunakan dalam industri kosmetik, parfum, dan medis. Penelitian ini bertujuan mengetahui hubungan usia panen dengan biomassa dan produksi minyak atsiri pada organ daun serta batang selasih. Penelitian menggunakan Rancangan Acak Lengkap (RAL) pola faktorial, dengan faktor pertama usia panen (1; 1,5; dan 2 bulan), dan faktor kedua organ tanaman (daun dan batang). Media tanam menggunakan tanah dan kompos (1:1) yang dimasukkan dalam polibag ukuran 30cm x 30cm, dan diberi naungan paranet 25%. Parameter yang diamati: data pertumbuhan (tinggi tanaman, jumlah daun dan cabang primer), biomassa, dan produksi minyak atsiri. Analisis data menggunakan Anaylysis of Variance (ANOVA) dan Duncan's Multiple Range Test(DMRT) pada taraf kepercayaan 95 %. Penelitian menunjukkan hasil bahwa tanaman yang dipanen pada umur lebih tua menunjukkan pertumbuhan, biomassa dan produksi minyak atsiri yang lebih tinggi. Pada usia 1,5 bulan, biomassa meningkat 114,485% dibanding usia 1 bulan, sedangkan pada usia 2 bulan, peningkatan biomasa 91,410%  dibanding usia1,5 bulan. Produksi minyak atsiri tertinggi dihasilkan oleh organ daun pada usia panen 2 bulan sebesar 0,273g, dan 0,023g pada organ batang. Kesimpulan penelitian ini menunjukkan bahwa usia panen berbeda berpengaruh nyata terhadap biomassa dan produksi minyak atsiri tanaman selasih. Basil (Ocimum basilicum L.) contains essential oils that can be used in the cosmetic, perfume, medical industries. This study aims to determine the relationship between harvest age and biomass and essential oil production in basil leaves and stems. The study used a completely randomized design (CRD) with a factorial pattern, with the first factor being harvest age (1; 1.5; and 2 months), and the second factor being plant organs (leaves and stems). The planting medium used soil and compost (1:1) which was put in 30cm x 30cm polybags and was given a 25% para net shade. Parameters observed: growth data (plant height, number of leaves, and primary branches), biomass, and essential oil production. Data analysis used Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) at a 95% confidence level. Research shows that plants harvested at an older age show higher growth, biomass, and essential oil production. At the age of 1.5 months, biomass increased by 114.485% compared to the age of 1 month, while at the age of 2 months, the increase in biomass was 91.410% compared to the age of 1.5 months. The highest essential oil production was produced by leaf organs at 2 months of harvesting at 0.273g, and 0.023g in stem organs. The conclusion of this study showed that different harvest ages had a significant effect on the biomass and essential oil production of basil plants.

The propagation of Cavendish (Musa acuminata L.) seedling conventionally relatively took a longer time, not uniformed in quality and possibly has a disease that is derived from unhealthy mother stock. This research aimed to find the effect of IBA and BA on difference concentrations on the growth of plantlet, also to determine the optimum concentration of IBA and BA on the growth of Cavendish bud plantlets in vitro. This research had been carried out started from April to July 2018 in Tissue Culture Laboratory, Research Institute of Horticultural Seed Development of Pasir Banteng, Sumedang, West Java. Indonesia. The method used in this research was Completely Randomized Design with two factors. The first factor was IBA (i0 = 0 mg L-1, i1= 0,75 mg L-1, dan i2= 1,5 mg L1), and the second factor was BA (b1= 1 mg L-1 b2= 3 mg L-1 b3= 5 mg L-1 b4= 7 mg L-1), replicated three times. Duncan Multiple Range Test (DMRT) was used as a further test. The result showed an interaction between IBA and BA on the parameters of shoot growth and the number of leaves at 6 WAC. IBA showed an independent effect on the number of buds. The addition of 1,5 mg L-1 IBA and 3 mg L-1 BA was optimum for the growth of Cavendish bud explants.

This study investigated the influence of plug cell volume ( 72 cell ( 36 mL ) and 128 cell tray ( 20 mL) ) and substrate type ( peat and cocopeat) on the development of cucumber seedlings. The experiment was designed in a factorial arrangement in a completely randomized design with four replications. The following growth data were measured: plant height, number of leaves, stem diameter and shoot and root biomass. The result showed significant differences among the treatments with respect to the plant height, stem diameter, as well as the shoot and root biomasses. Overall, it was found that growing cucumber seedlings in 36 mL cell volume with cocopeat produces a much better young plants for transplanting.

ABSTRACT This study had the following objectives: to identify and quantify the constituent compounds of essential oils from Cymbopogon winterianus Jowitt, Eucalyptus globulus Labill., Eucalyptus staigeriana F. Muell. ex F.M. Bailey, Foeniculum vulgare Mill., Ocimum basilicum L., Ocimum gratissimum L., and Piper hispidinervum C. DC., investigate their toxicity and repellency to S. zeamais and evaluate the toxicity of P. hispidinervum to immature S. zeamais. Individual tests for each essential oil were conducted with a completely randomized design with five concentrations for each oil and four replicates. Gas chromatography-mass spectrometry revealed the presence of citronellal in C. winterianus, 1,8-cineole in E. globulus, limonene in E. staigeriana, limonene in F. vulgare, linalool in O. basilicum, (E)-anethole in O. gratissimum, and safrole in P. hispidinervum. The median lethal concentration required to kill 50% of the insect (LC50) in contact and ingestion toxicity tests ranged from 5.12 to 78.89 μL 40g-1 corn in P. hispidinervum and C. winterianus, respectively. In adult fumigation tests, the LC50 ranged from 2.1 to 19.4 µL L-1 air, and in immature fumigation tests, the egg stage was susceptible to essential oil, whereas larval and pupal phases were tolerant. All of the oils repelled S. zeamais.

The study investigated that the effect of sulfur solutions as foliar spray with different concentrations on some selected growth parameters of ladies fingers plants. Pot experiment was conducted with six treatments (2g/L, 4g/L, 6g/L, 8g/L and 10g/L sulfur solutions) and three replicates. For each pot,two plants were maintained throughout the experiment. After seedling emerging, sulfur solutions were sprayed in every week using OSATU sprayer (5 L), until all the leaves got wet. After 30 days physiological features (Number of leaves, leaf length andleaf width) were recorded. Pest and disease incident also recorded at the mean time. Completely Randomized Design (CRD) with five replicates was used. Statistical analysis was performed with Duncan’s multiple range test using SAS software (version 9.1.3). Result showed that the highest significant values in number of leaves (26), leaf length (21cm) and leaf width (24cm) were observed that in 10g/L solution of sulfur applied as foliar spray. With the increasing concentration of sulfur solutions the values for the selected physiological features also increased. Pest and disease incidence was significantly higher in control experiment while all the other treated plants don’t showed any physiological damage or symptom. The results revealed that the application of sulfur as a foliar spray can be effectively use in increase the net photosynthetic area and to reduce the pest and disease incidence.

<p>ABSTRACT</p><p>Basil (Ocimum basilicum L.) is one of essential oil producers. Essential oil price fluctuates, one of the reasons is because of inappropriate cultivation which vary the supply. The research was conducted to determine the best rate of nitrogen fertilizer and the effect of biological liquid fertilizer on the essential oil production of basil. The experiment was arranged in Randomized Complete Block Design with two factors. The first factor was three levels of nitrogen rate: 0, 22.5, and 45 kg ha-1 and the second factor was two levels of biological liquid fertilizer rate; 0 and 2 L ha-1 for three replications of each treatment. Nitrogen increased the number of branches, flowers, and leaf length variables. Nitrogen rate of 22.5 kg ha-1 gave a higher economic value on the basil of essential oil production. Biological liquid fertilizer increased the height and number of basil leaves variables, but it was not impacted the yield and essential oil of basil.</p><p>Keywords: branches, distillation, fertilization, yield</p><p>ABSTRAK</p><p>Kemangi (Ocimum basilicum L.) merupakan salah satu sumber penghasil minyak atsiri.
