Salinity stress has negative effect on seed germination; therefore, it is necessary to find technology to mitigate it. The research was conducted to study the potency of peel extract of dragon fruit to mitigate salinity stress on soybean seed germination. This research used a randomized block design with factorial patterns and three replications. The first factor was the level of salinity of NaCl (C), consisted of 3 levels (c0 = 0%, c1=0.5%, c2=1%), The second factor was peel extract of dragon fruit (I), consisted of 3 levels (i0 = 0% (control), i1 = 1%, and i2=2%). The parameters analyzed were germination percentage, germination rate, root length, epicotyl length, electric conductivity, and dry weight of sprout. The data were analyzed with ANOVA and Duncan’s multiple range test at α = 5 %. The result showed no interaction between salinity stress and peel extract of dragon fruit on soybean seed germination. Salinity stress significantly decreased sprout vigor with the highest decrease was shown at 1% salinity; on contrarily peel extract of dragon fruit could maintain sprout vigor. Peel extract of dragon fruit 2% was the potential to mitigate salinity stress.

This research aims to determine the effect of tofu dregs compost and rice straw compost to growth of pepper cuttings. The research by experiment to determine the best dosage of tofu dregs compost and rice straw compost and to determine the relationship between P uptake and pepper cuttings growth. The experiment design was a factorial Randomized Complete Block Design consisting of two factors (dosage of dregs of tofu and rice straw compost) with 4 levels respectively, each of combination replicated 3 times. The dosage dregs of tofu compost are without dregs of tofu, 200, 250, and 300 g per plant). Dose of rice straw compost are without rice straw compost,75, 100, and 125 g per plant. The results showed that the combination tofu dregs compost and rice straw compost did not effect on all growth parameters. Application dregs of tofu compost of 300 g per plant and 75 g per plant of rice straw compost had an effect on the formation of roots and leaves. The relationship between growth and P uptake was not significant.

Breeding programs need genotypic variation to make a selection and create a promising variety. Hybridization in plants produces genetic variations in the offspring to select Robusta coffee as superior planting material. The maternal-effect and combining ability help determine the next breeding strategy. This study aimed to determine the maternal effect and the combining ability on the morphological characters of branches and leaves of Robusta coffee diallel crosses. The study involved six groups of F1 offspring and their reciprocals from three parents, namely clones BP961, Q121, and BP409, which were planted singly side in the Kaliwining Experimental Garden, Jember, East Java. The estimation of female parental effect was analyzed using a t-test, and combining ability was analyzed using diallel analysis method III. The analysis results showed that the female parental effect occurred on the character of the internode length in all cross combinations and did not occur on stipule length, petiole length, leaf length, and leaf width. The parent of the cross that can be the best combiner was parent BP961 for the petiole length and leaf length, parent Q121 for stipule length and internode length, and parent BP409 for leaf width character.

Tomatoes are easily damaged horticultural products, so that further handlings are needed in food production in the industry today. In order to keep availability, there is an increase in tomato fruit volume as raw material. Among them with increasing types and varieties of tomatoes that need to be continuously developed to supply the industry's needs. The research aimed to increase local tomato cherry production in Subang through an engineering strategy of nutrient feeding with a drip irrigation system. Research conducted from April to December 2019 at Cigadung Subang, West Java. The research was conducted using the Completely Randomized Design (CRD) one factor and the Duncan’s test at 7 nutritional dose treatment consists of P1 = dose 5 ml, P2 = dose 7 ml, P3 = dose 10 ml, P4 = dose 15 ml, P5 = dose 20 ml, P6 = dose 25 ml, P7 = Control with 5 repetition. The results concluded that two applications of nutritional doses at 7 and 10 ml could give different responses that increase the diameter and thickness of the fruits.

Shallot production in Central Sulawesi recorded a decline from 8.651-8.362 tons, between 2017-2018. However, the use of an accurate composition of the planting medium serves as a possible alternative to boost the yield. Also, the introduction of organic matter tends to increase the nutrient content, influence the aeration, and subsequently leads to drainage. This study is aimed at determining the effect of plant media composition on shallot growth and yield. A randomized block design comprising 4 treatments, termed soil composition, husk charcoal, and goat manure. Each treatment was repeated at 5 times to achieve 20 experimental units. The results showed that the plant media composition indicated a significant effect on the parameters of plant height at age 4 and 6 Weeks After Plantings (WAP), quantities of leaves aged 4 WAP, tillers aged 6 WAP as well as tubers per clump. Similar impacts were also reported on plant height at 2 WAP, the number of leaves aged 2 and 6 WAP, fresh tuber weight, tuber diameter, accumulated weight loss, root length, and available moisture content. Furthermore, the addition of husk charcoal and manure at a volume ratio of soil: husk charcoal: manures = 2:1:1, tends to increase the quantities of leaves, tillers, tubers per clump, as well as plant height, fresh tuber weight, and shallot bulb diameter.

Kombinasi BAP dan NAA untuk Media Perbanyakan Nanas Varietas Smooth Cayenne, Toboali in Vitro Nia Dahniar; Pepi Elvavina

Toboali pineapple variety is a smooth cayenne variety because it contains high antioxidants in the form of vitamins A and C. In addition, it is a source of citric and malic acids, substances that can be used to enhance the taste of the fruit. Pineapple is a plant that is propagated with vegetative organs such as suckers, slips, and crowns. However, conventional propagation has a low propagation rate. Tissue culture is an in vitro technique used in the rapid propagation of plants and in large quantities to meet the needs of cultivation and research. The selection of regeneration media is very influential on the development of plants in tissue culture. This study aimed to obtain the optimal media combination with BAP and NAA in the regeneration of Smooth Cayenne pineapple (Toboali) in vitro for mass propagation of seedlings and genetic engineering research. This study used 6 levels of BAP, namely 0, 1, 2, 3, 4, 5 mg.L-1 and 4 levels of NAA, namely 0, 1, 2, 3 mg.L-1. The treatment used was a combination of BAP and NAA as many as 24 treatments with 3 replications. The best pineapple regeneration medium for mass plant propagation in this study was BAP 3 mg.L-1 without NAA media which produced the highest shoots of 17.33 shoots per explant at 12 week after planting. The best pineapple regeneration medium for genetic engineering research was a combination BAP 3 mg.L-1 and NAA 2 mg.L-1 media which produced 18.33 shoots per explant from embryogenic callus.

Various fruit flies are in Indonesia, but only a few species of fruit flies have been found at the red guava plant in Deli Serdang District. Knowing the species of fruit flies are needed to do the proper control. In addition to morphological identification, it is necessary to carry out molecular characterization to obtain accurate results in characterizing species differences. This study aims to identify the fruit fly based on morphology and molecularly PCR-RAPD for mapping the genetic closeness of the relationship between individual fruit flies. Bactrocera morphologically identified at LIPI, namely B. carambolae, B. papayae, B. caudata, B. albistrigata, B. umbrosa, B. curcubitae, B. tau, and B. kinabalu. For molecular identification PCR-RAPD, shows the dendrogram results from the Neighbor-Joining analysis based on RAPD markers of DNA band characters showing the genetic proximity of eight species divided into three groups of Bactrocera based on their location. The closeness of genetic relationships between individuals was analyzed using Pairwise Distance Calculation which describes the genetic distance between species. The results of Pairwise Distance Calculation ranged from 0.13-0.42. By knowing what species there fruit flies are in red guava plantations in the Deli Serdang district, it can make it easier for farmers to monitor and control fruit flies in red guava plantations.
