Ku’u cake is a traditional food made from glutinous rice flour filled with green beans, has a chewy texture and has a pink pigment. The Ku cake is shaped like a turtle shell. The research objectives were to determine the addition of secang wood solution that can be used as a natural dye, to determine the anthocyanin levels, antioxidant activity, and to determine the level of acceptance of the panelists from traditional ku dumplings with natural dye of secang wood. The design in this study used a completely randomized design (CRD) with 4 treatments (P0: synthetic dye (control), P1: 2% secang wood synthetic dye, P2: 4% secang wood synthetic dye and P3: secang wood synthetic dye 6%) . The results showed the effect of making the cake using synthetic dyes with secang wood solution had a significant effect on anthocyanin levels, antioxidant levels and color levels. The values of anthocyanin levels at P0, P1, P2, and P3 were: 2.51, 3.27, 3.79 and 4.45, the antioxidant levels were (P0: 2.15 P1: 3,38 P2: 4,27 and P3: 6,49) and the color content, P0: 30,54 P1: 43,98 P2: 33,06 and P3: 32,43. For organoleptic test results on color, taste, aroma and texture, the recommended treatment is P1.

Callosobruchus Chinensis is a pest that damages mung bean seeds in storage and causes damage to both the quality and quantity of seeds. This study aims to determine the effectiveness of neem leaf extracts in suppressing the development of the Callosobruchus Chinensis pest as one of the postharvest pests in the commodity green beans. This research conducted at the Laboratory of the Faculty of Agriculture, University of Flores, by using a Completely Randomized Design (CRD) with five treatments and three replications. The concentration of neem leaf extract treatment is 0 ml / l, 25 ml / l, 30 ml / l, 35 ml / l, and 40 ml / l. The results showed that the concentration of neem leaf extract 40 ml / l caused mortality of C. Chinensis imago as contact poison by 99% and nerve poison by 47%. While the effectiveness of the limb leaf extract on spawning activity was 86%.

One of the entomopatogenous fungus types commonly observed and showed potency as myco-insectiside is Beauveria bassiana(Bals.) Vuill.In order to support effectiveness and patogenous activity of B. bassiana, it is necessary to add a carrying agent that protects its spores from ultra violet ray. This study aims to investigate the effect of storage temperature on viability of B. Bassianaspores on the carrier material. The observation was carried out in the Laboratory of Plant Diseases, Indonesian Coffee and Cocoa Research Institute. The research was arranged in completely randomized design by three factors. The first factor was carrier (C), that consists of C1 = rice flour, C2 = maize flour and C3 = tapioca flour. The second factor was dosage (D), that consists of D1 = 1 g B. bassiana+ 1 g carrier; D2 = 1 g B. bassiana+ 5 g carrier and D3 = 1 g B. bassiana+ 10 g carrier. The third factor was temperature of the storage (T),that consists of T1 = 5oC; T2 = 23oC and T3 = 29oC. Viability of B. Bassiana spores was examined by observing development of 100 blastopores randomly and determined under light microscope with 400 times magnification. Observation was conducted in two replicates after the spores of B. bassiana were kept in the storage for 2, 4, 8 and 16 weeks. The result showed that by adding 1 g tapioca flour and temperature of storage of 5oC was potentiall in keeping viability of B. bassianaspores at least for 2 months. It was due to that tapioca flour gave better effect than rice and maize flours in keeping the storage and appropriate low temperature. Viability of B. bassianaspores decreased with increasing carrier dosage, temperature and duration of the storage. Whereas, storage at 5oC was found to be a better condition in keeping viability of dry pure B. bassianaspores longer than conditions of 23o and 29oC. Key word:Beauveria bassiana, temperature, viability,carrier.

Abstract. Sarwono, Santosa S, Prameswari NS. 2019. Short Communication: The color fastness of cotton cloth dyed with dye extracted from skin of shallot (Allium ascalonicum). Biodiversitas 20: 2475-2479. Inventing new sources of materials in textile coloration industry in Indonesia, especially batik industry, is necessary for the preservation of Indonesia’s textile heritage. Focusing on the exploitation of Allium ascalonicum L., this present study aimed at discovering whether shallot skin can be used as a natural dye for textile through the fixation of alum, chalk, and tunjung. It also tried to shed light on the method of applying dye from the skin of shallot to cotton cloth for batik and measured the color fastness. The test of color fastness was done using Staining Scale and Grey Scale. Data were gathered through observation and analyzed descriptively. The results of color fastness test showed that the color fastness of cotton cloth dyed with extract of shallot skin using alum fixation was fairly good based on color change and sufficient based on staining scale. The test results using chalk fixation showed that the color fastness was poor based on color change, but sufficient based on staining scale. Other results with tunjung fixation showed that the color fastness was sufficient.

<p>Green beans are legume plants that are in great demand because of their high nutrition content and include plants that require boron to support growth from the vegetative to generative phase. The study aims to assess the growth and production of green beans due to influence of the dose and time of boron application. The research was carried out using completely randomized design with factorial pattern 3×3 with 3 replications. The first factor was the treatment of boron doses of 1, 1.5, and 2 kg/ha was given once at 7 Day After Planting (DAP), fertilizer application twice at 7 and 28 DAP, and once given at 28 DAP. The results showed that dose of boron at a dose of 1 kg/ha was able to produce the number of affective root nodules and the best pod weight. The treatment of boron once at 7 DAP can increase plant height, flowering age, pod weight, and seed weight per pod. The interaction between dose and time of boron application affects the number of affective root nodules and seed weight per pod.</p>

The purpose of this research is to determine the optimal dose of the addition of red spinach powder to artificial feed on the brightness of clown loach. This research was conducted at Aquaculture Laboratory Building 4 Faculty of Fisheries and Marine Sciences of Universitas Padjadjaran from April to May 2020. This research method is experimental with a Completely Randomized Design consisting of four treatments and three replications. The red spinach powder addition treatment used 0%, 2%, 4%, and 6% of the feed amount. The parameters observed are color value as primary data by using Toca Color Finder, while the growth, survival rate, and water quality as support data. Color assessment results were analyzed using the Kruskal-Wallis test, if there were significant differences, Z test would be performed. Growth data and survival rates were analyzed using Analysis of Variance (ANOVA). Because the F test results were not significantly different, the Duncan test was not carried out. The results showed that the addition of  6% red spinach powder is the best treatment with an increased color brightness value of 5,63.

Nutmeg oleoresin microcapsule is the solid, liquid, and gas coating technology of the nutmeg fruit.  The purpose of this study was to know how mace nutmeg oleoresin microcapsules could preserve the broiler chicken meat at room temperature during 4 days of observation. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments with mace concentration of nutmeg microcapsules oleoresin (0, 50, 100, 150, and 200) ppm. The variables observed were water content, pH value, total microbes, and organoleptic properties (color, aroma, and texture). The results showed that mace nutmeg oleoresin microcapsules did not affect (p> 0.05)  water content and sensory properties of broiler chicken meat, but had a significant effect (p <0.05) on the pH value and total microbe at the same day of room temperature storage. Panel organoleptic test results on the level of preference for meat color, aroma, and texture of chicken meat were in the range score of 3 (somewhat like) to 4 (somewhat dislike). The treatments of nutmeg oleoresin did not affect (p> 0.05) on color, the aroma, and the texture of broiler chicken meat. This research shows that marinating using oleoresin microcapsules has not been effective as a preservative to broiler chicken meat at room temperature. Keywords: chicken meat, mace nutmeg oleoresin microcapsules
