Abstract

Fruit flies (Bactrocera sp.) are the most common types of plant pests attacking fruit plants. The pest attacks the fruit in the plantation. The control of fruit flies is quite difficult, which is usually done by using eugenol. Fruit flies are insects that are sensitive to light with wavelengths of 300-650 nm. The light trap is a method commonly used yet it is rarely used to control the fruit flies. This research was conducted to determine the effect of the color variation in light traps on the number of trapped fruit flies. This study used quasi-experimental research methods. The data were analyzed descriptively and continued with one-way ANOVA statistical testing using SPSS 25.0. The results showed that the highest average number of fruit flies was in light traps with the addition of blue lights of 17.22. Post hoc tests showed that blue lights were more effective in attracting flies into light traps.

Abstract

Echinacea (Echinacea purpurea (L.) Moench) is a medicinal plant known to boost the immune system. Propagation is necessary to increase production. One of the methods of propagation in tissue culture. This research was conducted to understand the most suitable concentration of plant growth regulators. The treatment was given a combination of Benzyl Adenine (BA) and Indole Butyric Acid (IBA) with BA concentration of 1 ppm, 2 ppm, 3 ppm and 4 ppm while the IBA concentration used was 1 ppm and 2 ppm. The next step was subculture by using the combination among IBA 0 ppm, 0.5 ppm, 0.75 ppm and BAP 0 ppm, 0.5 ppm, 0.75 ppm of BAP. The result showed that the most shoots produced by the combination treatment of BA 2 ppm and IBA 1 ppm while the highest shoot and leaf number is best produced in treatment BA 1 ppm and IBA 2 ppm. The largest number of shoots was shown by treatment BA 2 ppm and IBA 1 ppm. This study can be concluded that BA 1 ppm and IBA 2 ppm, and BA 2 ppm and IBA 1 ppm gave the best treatment for shoot growth and control for root induction.

Abstract

Bark consumption is defined as the thickness of sliced bark per time unit. This research, aiming to identify the effects of direction, panel height, and tapping frequency on daily bark consumption, was carried out at Sungei Putih Research Center, North Sumatera and several estates in Lampung (Kedaton, Bergen, and Way Lima) from January to March 2018. The observations involved 15 tapping tasks consisting of GT 1, PB 260, and mixed clones. Bark samples were collected from 10 randomized trees in each task. Tapping direction was distinguished as downward tapping and upward tapping, while panel height was classified into 50 cm, 50 – 100 cm, and 100 – 130 cm in downward tapping and 130 – 150 cm, 150 – 170 cm, and 170 cm in upward tapping. Tapping frequency effect was investigated in a trial plot using frequency of once in three days (d3), once in four days (d4), once in five days (d5), once in six days (d6), and once in eight days (d8) on the basal panel (B0-2). Bark consumption was measured directly using a digital caliper. The observation result indicated that upward tapping had higher bark consumption than downward tapping. In downward tapping, the lower tapping position, the higher bark consumption would be, whilst in upward tapping, bark consumption increased along with the panel height. Low tapping frequency (d4, d5, d6, and d8) showed higher bark consumption per tapping than d3, yet they had lower cumulative bark consumption per year.

Abstract

A surfactant that can be developed from palm oil is non-ionic. Diethanolamine is a nonionic surfactant based on palm oil methyl ester, which can replace the use of polyoxyethylene amine surfactant in a commercial herbicide formula that harms the environment. This research aimed to determine the physicochemical properties of diethanolamine surfactant and to study the effect of diethanolamine surfactant addition in herbicide formulation with active ingredients of isopropylamine glyphosate. This study was arranged in a complete randomized design with surfactant concentrations as treatment, consisting of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 4%, 5%, 6%, 7%, 8%, and 9% (w/w). The results showed that there was a significant effect of diethanolamine surfactant addition on the characteristics of the herbicide formulation. The concentration of 5% diethanolamine surfactant had the best character in producing herbicide with the lowest surface tension and a contact angle of 30.73 dyne/cm and 11.48°. The commercial herbicide, having a surface tension of 36.27 dyne/cm and a larger contact angle of 83.03°, was used as the comparison for the formulations. The stability of the solution was up to 100% for 5 weeks at room temperature with solubility in water of 80.60% and droplet size of 7.20 ?m.

Abstract

Various potato clones are cultivated by farmers in Banjarnegara and Wonosobo, Central Java, Indonesia such as MZ, NH1, NH2, Vega, Gareta, Granola, Bliss, Merah (Red Potato), Ungu (Purple Potato), Klon_17 (K17), Local Dieng, Margahayu, and X. This encourages the importance of genetic diversity and genetic similarities. This study aimed to analyze genetic diversity and genetic similarities between 13 accessions of potatoes based on seven Random Amplified Polymorphic DNA (RAPD) primers and nine pairs of Simple Sequence Repeat Marker (SSR) primers. The results showed that RAPD and SSR primers could be used to analyze genetic diversity and genetic similarities of 13 potatoes accessions from Banjarnegara and Wonosobo. The PLP value was 80.9% in the RAPD primer and 65.41% in the SSR primer. Four RAPD primers were informative based on PIC value: OPG 08, OPM 19, OPP 13, and OPX 04. Three SSR primer were informative: STM 2005, RGH- SSR 8, and StI 035. Genetic similarities presented by Phylogenetic tree analysis resulted in two main clusters. The first cluster consisted of Granola, MZ, Ungu (Purple potato), Merah (Red Potato), Local Dieng, Margahayu, Gareta, Vega, NH2, NH1, Klon_17 (K17), and Bliss. The second cluster consisted of X. Granola and MZ having a high genetic similarity with a genetic distance of 0.07 and 0.132. Meanwhile, K17 and X had a low genetic similarity with a genetic distance of 0.31 and 0.987.

Abstract

Strawberry (Fragaria spp.) has a high economic value and various benefits, but the production of strawberry plants in Indonesia is still low in terms of both quantity and quality. Strawberry plant breeding can be done in various techniques, one of which is polyploidization. Polyploidization by an induction of colchicine at various concentrations in strawberry crops cv. California and Festival resulted in superior phenotype characteristics. To prove the existence of a change in ploidy in strawberry, then research at the molecular level needs to be done. The purposes of this study were to find out changes in ploidy of strawberry plants using CAPS molecular markers and to detect the polymorphism in strawberry plants quickly. The samples used were young leaves. Main procedure was the cutting of the amplified DNA using restriction enzymes of TaqI and HaeIII. The results showed that CAPS molecular markers were capable of detecting polymorphism quickly and efficiently in strawberry plants. Specific bands among strawberry plants having undergone polyploidization and those not having undergone polyploidization can be seen on the differences in monomorphic or polymorphic bands between the control plants and treated plants.

Abstract

High yield potential (more than 8 ton ha-1), resistant to pest and disease, adaptive to specific or broad environment and good palatability are among rice traits preferred by farmers and consumers. In order to develop such superior rice, yield testing at different agro-climates for some promising lines bred is necessary. This study aimed to examine selected rice genotypes in two different environments, namely Indramayu (9m asl) and Jatinangor (752m asl) and to obtain environment factors affecting the plant trait variation. The experiment was conducted during dry season with fifteen F5 genotypes, arranged in an augmented design. Based on Least Significant Increase (LSI), genotypes showing better performance than checks were SP87-1-1 on number of productive tillers and total grain weight, SP73-3-1 on panicle length, total grain weight, and weight of 1000 grains. Meanwhile, SP46-4-1 and SP87-4-1 showed better number of filled grains than checks in Indramayu. There was no genotype performing higher number of empty grains than that of the checks. Based on the Principal Component Analysis (PCA), altitude contributed to high variation of plant traits. SP87-1-1 and SP73-3-1 are recommended to be grown in medium and lowland ecosystems because they have high productivity in both environments.

Abstract

The use of synthetic inorganic fertilizers containing chemical compounds cause soil quality to decrease. Chromolaena odorata are potential weeds used as a source of organic matter, which can be used as compost. This research aimed to determine the effect of Chromolaena odorata compost on the soil and nutrient uptake of lettuce. The research was conducted using a single factor experimental method arranged in a Randomized Complete Block Design. The treatments tested were the applications of C. odorata weed compost at various doses (222 grams/pot, 444 grams/pot, and 666 grams/pot) with control treatments of 200 ml/pot NPK Phonska (15:15:15), 320 grams/pot cow manure, and without fertilization. The experiment consisted of three blocks with three samples and three units of sample plants within each treatment. The results showed that the application of C. odorata weed compost significantly improved nutrition and nutrient uptake of lettuce. The dose of 444 grams/pot C. odorata weed compost was the best dose to increase soil quality and nutrient uptake of lettuce.

Abstract

This study aimed to determine the growth and yield responses of four soybean cultivars to different methods of N, P, and K fertilizers application. The methods consisted of one-time application (at the planting time) and split application (at the planting time and during the initial stage of pod formation (R3 stage)). Four superiors soybean cultivars were used, namely Anjasmoro, Grobogan, Dena-1, and Argomulyo. One-time fertilizers application resulted in an increased plant height compared to split fertilizers application. In contrast, the split fertilizers application led to a higher yield of soybeans indicated by the higher total number of pods, number of filled pods, 100-grain weight, and seed dry weight. Cv. Anjasmoro produced higher growth and yield than cv. Grobogan, Dena-1, and Argomulyo. It also produced the highest yield compared to other cultivars. Meanwhile, cv. Argomulyo produced the lowest yield in both fertilization methods. Based on the soil analysis after harvest, the nutrient content of K in the soil was higher than before planting in both fertilization methods. In addition, the split fertilizers application led to higher utilization of P in the soil after harvest.
