ABSTRACT Sweet bread is associated with smooth texture and high carbohydrate content, tasty and filling - quality that makes it preferred for snack. The key is in formulating raw material and other components. Commonly, sweet bread has short shelf life. Frozen dough could be the solution to this problem, and glucomannan addition during freezing process should be able to improve its physicochemical characteristics. This research aims to determine the effect of adding modified arrowroot (Maranta arundinacea L.) starch (MAS) as substitution, and glucomannan as frozen dough cryoprotectant toward sweet bread’s physicochemical. Randomized Complete Block Design Factorial (RCBD) was applied, and two factors were studied. The first factor was modified arrowroot starch (0.00%, 3.75%, and 7.50%) and the second was glucomannan (0.0%, 0.5%, and 1.0%). The best result was combination between MAS 3.75% and glucomannan 0.5%, reaching dough expansion volume range of 50% to 60%, bread expansion volume range of 77% to 80%, hardness range of 2 N mm-2 to 3 N mm-2, elasticity range of 88% to 96%, moisture content of 16% to 19%, ash content of 1.4% to 1.7%, fat content of 10% to 15%, protein content of 5%, and carbohydrate content of 51% to 66%. MAS is able to substitute wheat flour in bread production only if it is combined with glucomannan.

Crackers are a type of biscuits produced through a fermentation process. They are crunchy, have a flat shape and a rather salty taste, and when broken, they show a multi-layered cross-section. A study on the effects of the addition of siamese gourami fish meal on the sensory and physicochemical characteristics of crackers was carried out at the laboratory of Fishery Technology. This research used a randomized block design with five treatments of different types of the concentration of siamese gourami fish meal, i.e. 0%, 5%, 10%, 20% and 30%. The observed parameters were sensory characteristics, physical characteristics (color and crispiness) and chemical characteristics (water content, ash content, protein content, fat content, and carbohydrate content). The results suggest that the addition of siamese gourami fish meal significantly affects the sensory characteristics (appearance, odor, color, texture and crispiness), as well as chemical characteristics (ash content, moisture content, protein content, fat content, and carbohydrate content). The best treatment found in this research was A2 (20 g fish meal : 180 g wheat starch).

Eucalyptus is among the most widely cultivated forest trees in the world over 22 million hectares (ha). It provides major raw material for the pulp, plywood and paper industries in India, so it is imperative that planting stock of high genetic quality be used to increase the yield from plantations. In India, Eucalypts are in improving stage for adoption at larger level and choice of suitable clones is still a big challenge in eastern part of Uttar Pradesh. To assess the suitable clones of Eucalyptus for this region, an experimental trial was established under statistical design of Randomised Block Design for 13 clones (IFGTB 1,2,3,4,5,6,7,8,9,10, FRI-100,104,124) of 02 eucalyptus species (E. tereticornis and E. camaldulensis). The soil analysis indicated pH 9.3, EC 0.89 mm/cm, organic carbon 0.21%, Nitrogen 47.3 kg/ha, Phosphorus 11.3 kg/ha and Potassium 184.8 kg/ha. The highest value of annual increment in gbh belonged to clones IFGTB 6 (5.18 cm) followed by IFGTB 8 (5.12 cm), IFGTB 2 (4.74 cm), IFGTB 5(4.36 cm) and IFGTB 10 (4.02cm) amongst IFGTB series whereas in FRI clones, clone FRI 100 performed superior with 3.03 cm increment in girth after one year of planting. The lowest values belonged to clone IFGTB 9 and DDN 124 with 2.44 cm and 2.49, respectively. The clones with good annual increment in height were IFGTB 2 (3.85 m) followed by IFGTB 6 (3.80 m), IFGTB 10 (3.77 m) ,IFGTB 8 (3.55 m) and IFGTB 5 (3.30 m) in IFGTB series whereas in FRI series, FRI 100 (2.70 m) performed superior over other two clones. The survival of plants was in range of 66-100%. The clones of species E. camaldulensis in IFGTB series performed better over other clones/species. The evaluation of Eucalypt clones will be helpful for identification of promising clones for the specific region, thus, planting stock of desired clones may be raised for their further cultivation in field. The expansion of plantations of Eucalyptus in agro forestry will be helpful in reducing pressure of forests, increasing trees outside forests and upgrading the economic level of farmers.

The objective of this study was to evaluate the effect of nitrogen sources and rates on the physicochemical characteristics and yield of tomato plants. Forty hybrids were cultivated at 100 and 400 kg ha-1 of N, combined with four sources (urea, ammonium sulfate, ammonium nitrate and calcium), plus a treatment without N application in a randomized complete block design four replicates. Size, stem diameter, number of leaves, SPAD (Soil Plant Analysis Development), leaf nitrogen, number of fruits / plants, fruit firmness, bark thickness and average fruit size, ° BRIX, pH, calcium, potassium and sodium in fruits. There was an increase in SPAD index, Brix and longitudinal diameter of fruits as a function of the N dose. The use of ammonium nitrate and calcium provided stronger fruits. Urea and ammonium nitrate provided the highest pH value in tomato fruits. The application of the 100 kg ha-1 dose of N resulted in the highest potassium content in fruits. The highest productivity was obtained with the application of sources containing ammonium and the lowest in the control treatment. Sources and doses of nitrogen fertilizers influenced growth, productivity and parameters related to tomato quality.

Knowing the cause and effect among two or more traits can help to increase the selection accuracy of superior genotypes. The main objective of this study was to evaluate the cause and effect relationship between expansion volume and kernel size in popcorn hybrids using path analysis and Bayesian network. A total of 41 popcorn hybrids were evaluated through a randomized complete block design (RCBD) with two replicates in the city of Jaboticabal, Brazil. The assessed traits were grain length (GL),grain thickness (GT), grain width (GW), caryopsis roundness index (CRI), mass of 50 grains (MG), and expansion volume (EV). Measurements were performed on individual grains, using three 50-grain samples from each plot. Pearson’s correlation coefficient, path analysis and Bayesian network were estimated. A negative correlation was detected among EV and the traits, except for GT. Path analysis indicated that MG has a direct and positive effect on EV and the negative correlation observed is mainly due to the indirect effects by GL and GT. Bayesian networks did not detect a direct association between kernel size and expansion volume while indicating that GT is the only trait that can affect popcorn flake size.

AbstractThe challenge related to waste management has become a serious worldwide environmental problem. Highly sustainable solutions, which do not involve reworking the material and are based on waste utilization, are sought. Such waste as used casting compounds, which so far has been used, among others, in construction, road construction, mining and cement production. Descriptions of the use of various waste moulding compounds, such as waste quartz compounds with water glass, quartz chamotte and quartz bentonite can be found in the literature. Due to the high content of quartz and low toxicity of bentonite sandmix, an attempt was done to use them for the production of sand-lime products.The aim of this article is to determine the suitability of the waste material as a substitute for quartz sand in the production of sand-lime products. The usability of waste was determined by laboratory tests of physicochemical characteristics of the finished silicates. Sand, which is a carrier of silica, was replaced with used moulding compounds with fractions up to 0.5 mm, in the weight amounts of 5.5, 11 and 16.5%. Applying up to 11% of used casting materials as a substitute for quartz sand with a lime content of 5.5% in the raw material mixture has a clearly positive effect on compressive strength. However, the higher share of sand substitution in the mixture weakens the mechanical features of the obtained materials. The absorptivity of the finished products increases with the increase of the inserted additions’ amounts. The influence of significant amounts of casting compound additives on the microstructure of calcium-silicate products was studied as well. It was stated, that they affect the location of the tobermorite in the volume of the autoclaved material.

ABSTRACT Sandalwood (Santalum album Linn.) Is a native species of East Nusa Tenggara that have high economic value because it contains oil in the hardwood that is used as a raw material for cosmetics and pharmaceuticals. However, sandalwood population in East Nusa Tenggara has declined severely caused of massive exploitation in the past without accompanied by the success of replanting. Excessive exploitation impact on the decreasing of genetic diversity. Conservation was initiatied by the Forestry Research Institute of Kupang in 2012 with Eastern Part of Timor Island as a genetic material source. This study was aimed to investigate the genetic variation of plant growth on sandalwood (Santalum album linn.) genetic conservation from Eastern Part of Timor Island until 8 months after planting. The research was designed using Incomplete Block Design (IBD), consists of 25 families, single treeplot and 10 blocks as replicates. The variance analysis showed there was no significant difference between the families tested and the average height and diameter growth of test plants respectively 51,02 cm and 4.70 mm. The families heritability (h2f)  estimation of height is 0.70 high category and the diameter is 0.53 medium category.   Key words : Population, conservation, variation, heritability ABSTRAK Cedana (Santalum album Linn.) merupakan jenis tanaman asli Nusa Tenggara Timur yang memiliki nilai ekonomi tinggi karena kandungan minyak atsiri pada kayu terasnya yang digunakan sebagai bahan baku industri kosmetik dan obat-obatan. Namun demikian populasi jenis ini di Nusa Tenggara Timur telah mengalami penurunan sangat tajam, akibat eksploitasi besar-besaran dimasa lalu yang tidak dibarengi keberhasilan penanaman kembali. Kondisi tersebut berdampak pada keragaman genetik cendana yang pernah ada di NTT. Tindakan konservasi mulai dilakukan oleh Balai Penelitian Kehutanan Kupang pada tahun 2012 yang berasal dari populasi Pulau Timor bagian Timur. Penelitian ini bertujuan untuk mengetahui variasi genetik pertumbuhan tanaman pada plot konservasi sumberdaya genetik cendana populasi Pulau Timor bagian Timur sampai dengan umur 8 bulan setelah penanaman. Penelitian disusun dengan rancangan Incomplete Block Design (IBD) yang terdiri dari 25 famili, single treeplot dan 10 blok sebagai ulangan. Hasil analisis varian tidak menunjukkan adanya perbedaan nyata antar famili yang diuji dengan nilai rerata pertumbuhan tinggi dan diameter masing-masing sebesar 51,02 cm dan 4,70 mm.
