"Perbedaan Sifat Fisik, Kimia dan Sensoris Tepung Umbi Suweg (Amorphophallus campamulatus BI) pada Fase Dorman dan Vegetatif"
Umar Hafidz Asy’ari Hasbullah, Rini Umiyati
Abstract
This study aims to determine ofdifferences in physical, chemical and sensory properties of suweg flour from the dormant and vegetative phases. Physical parameters include yield, edible portion, bulk density, brightness, particle size index, water absorption index and water solubility index. Chemical parameters include the moisture, ash, fat, protein, carbohydrates, starches and sugars reduction. Sensory parameters include hedonic test of color and aroma as well as descriptive test of color and aroma. The results showed that the physical characteristics of flour suweg dormant phase and vegetative phase significantly different at all parameters. Yield, edible portion, bulk density, brightness, particle size index of dorman phase higher than vegetative phase. Chemical characteristics from dormant phase and vegetative phase were significantly different at all parameters, except fat and carbohydrate. Starch contain in dorman phase higher than vegetative phase. But in contrast to the sugar reduction contain. Panellists assess the suweg flour produced from the vegetative phase has a more brown color and smells stronger than the dormant phase so it is less preferred color and aroma. Suweg flour should be selected from the dormant phase. Utilization of flour suweg is recommended for products such as cookies and biscuits that can be grown ingredients to cover the presence of brown and off flavor.

Abstract
To improve yield and cup quality, mature coffee tree as rootstock could be grafted with scion of selected genotype. This research aimed to study growth performance of mature trees resulted from intra and inter-specific grafting on Robusta coffee. The research was arranged in Randomized Complete Block Design with 3 replications. There were 12 treatments of entrees/under-stump genotype for coffee grafting including 8 treatments of intraspecific local Robusta/Robusta grafting and 4 treatments of interspecific coffee grafting of Robusta/Liberica and Arabica/Robusta. The results showed that intraspecific grafting of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta resulted in grafting mortality of 9.8%, 10.9%, and 24.8%, respectively. Until 28 weeks after grafting, branch growth variables were significantly affected by scion/rootstock of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta grafting. Grafted Arabica/Robusta coffee showed the poor growth performance. In second year of Robusta/Robusta and Robusta/Liberica growth, generative growth of cherry inflorescence per branch and number of cherries per inflorescence were not affected by scion and rootstock genotypes. Leaf and branch growth were very important variables correlating with other variables.

Lily Ismaini, Suluh Normasiwi, Muhammad Imam Surya, Destri Destri

Abstract
Rubus fraxinifolius belonging to the wild raspberry group has not been developed in Indonesia. Mutation breeding using gamma-ray as mutagen which was combined with in vitro culture is one of acceleration effort to obtain superior characteristics of the fruit crops, such as larger fruit size, higher nutrition content, plant with less of spines and fruit storage ability. The R. fraxinifolius seeds were irradiated with different doses of gamma-ray ranging from 0 to 500 Gy using the 60Co (Cobalt). This research aimed to determine in vitro growth of R. fraxinifolius mutant (M1) after irradiation using gamma-ray. The results showed that the highest percentage of seed germination was obtained on the doses of 100 and 200 Gy. Furthermore, the subculture of R. fraxinifolius mutant (M1) on MS medium with the addition of BA showed the different growth on number of shoots, number of leaves, and plantlet height. Moreover, R. fraxinifolius control showed higher value of shoots, number of leaves, and plantlet height at 4 and 8 weeks after subculture compared to R. fraxinifolius mutant. MS medium with the addition of IBA showed that the number of roots of R. fraxinifolius control (5.75) was higher than that of R. fraxinifolius mutant (M1) (4.83).

Abstract
Complementary food should be added to the diet of the babies in addition to breast milk from 6 months onward and the food should be sufficient for the baby’s nutrition needs. Complementary feeding using baby biscuit made of yellow pumpkin flour and the addition of coconut flour is an effort to improve nutrition through local food diversification approach. The purpose of this study was to determine the best biscuit formulation and to test the physicochemical properties of the selected formula. This research used completely randomized experimental design consisting of four formulae of yellow pumpkin flour, i.e. 10%, 15%, 20% and 25%. The results of organoleptic tests showed that the best formula of the biscuit as complementary food is 25% yellow pumpkin flour and 12% of coconut flour. Consumption of two servings of biscuits can meet the nutritional adequacy of the babies except calcium. The biscuits can be kept for 92 days 8 hours under open conditions. In addition, the biscuits have good physical properties in terms of water absorption and hardness."

"Effects of Ascorbic Acids on Post-Harvest Longevity of Chrysantemum Cut Flowers"
Kurniawan Budiarto
Abstract
The longer vase life of chrysanthemum cut flower is one of the preferable quality traits in marketing for growers, retailers and consumers. Several compounds, like ascorbic acid, have been reported to be able to prolong the post-harvest quality and longevity of cut flowers. Thus, the purpose of the study was to assess the ascorbic acid effects in several concentrations (0, 100, 200, and 300 ppm) in extending the fresh life of two chrysanthemum cultivars, i.e. cv. Remix (spray) and Yellow Fiji (standard). The results showed that the termination of flower freshness was visually characterized by wilting of leaves and florets and the change in floret color (paler). The supplementation of ascorbic acid solution at the concentrations of 200 and 300 ppm prevented and lengthened leaves and florets turgidity and postponed the wilting up to 2 – 3 days compared to control. At the same concentrations, the solution also slowed down the degradation rates of chlorophyll content on leaves during vase life periods.

"N Absorption in Nontidal Rice Fields Treated with Microalgae and Nitrogen Fertilizer Application"
Nova Tri Buyana, Nuni Gofar, A. Madjid Rohim

Abstract
Nutrient elements that are needed by plants during its growth and development is nitrogen. Nitrogen deficiency can cause plants to become necrosis so that plants are not able to photosynthesize well, thus result in lack of food needed by plants. Microalgae can provide nitrogen for rice crops due to its activity. The aim of this research was to know the effect of microalgae from nontidal swamp land to reduce the use of inorganic N fertilizer in paddy field. The study was conducted from January to April 2017, using factorial completely randomized design with two factors, namely isolate and dosage of nitrogen fertilizer. The first factor is the type of the isolate (I), consisting of cultures from the area of rice cultivation (I1), the culture originating from the area around the rice fields (I2) and the cultures of area without rice cultivation (I3) area. The second factor is the dose of nitrogen fertilizer (N) consisting of 0%, 50% and 100%. The results showed that the treatment of the isolate (I) or dosage of nitrogen fertilizer had a significant effect on the weight of 1000 filled grains and the weight of empty grains in the generative phase of rice plant. The interaction between both treatments had a significant effect on the generative (production) phase. The microalgae culture from area of rice cultivation (I1) can contribute nitrogen requirement of 16.23% - 48.71% with an abundance of 7.48 cells ml-1, with the requirement of rice plant nitrogen fertilizer of 45-135 kg ha-1.

Purwanto Purwanto, Tridjoko Agustono, Bambang Rudianto Widjonarko, Teguh Widiatmoko

Abstract
The aim of this research was to examine the diversity of indigenous plant growth promoting rhizobacteria from paddy soil and to obtain a superior isolate that can support the growth and vigor of rice plants. This research was conducted in the Laboratory of Agronomy and Horticulture, Faculty of Agriculture, Jenderal Soedirman University from July to September 2017. The bacteria were isolated from paddy soil rhizosphere originated from rice production centers of Banyumas Regency i.e. Kebasen, Rawalo, Patikraja, Jatilawang, and Karangwangkal. Results showed that indigenous PGPR from paddy soil were able to produce Indol Acetic Acid (IAA) in the range 0.05-5.40 ppm, but did not have the ability to solubilize phosphate. Plant Growth Promoting Rhizobacteria (PGPR) inoculation in rice seedlings was able to increase seed vigor, plant height, root length, and seed germination. Based on morphological and biochemical characters, PGPR isolates were identified as Bacillus sp., Pseudomonas sp., Streptococcus sp., and Staphylococcus sp.

"The Effect of Light Color Variation in Simple Light Traps on the Number of Fruit Flies (Bactrocera sp.)"
Eka Sobiatin, Herianto Herianto, Nur Khosiyatun, Heru Kuswanto

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.

"Methane Emissions and Rice Yield in Rainfed Bed System (Surjan) as Affected by Manure and Zeolite Treatment"
Anggri Hervani, Helena Lina Susilawati, Anicetus Wihardjaka

Abstract
Rainfed area as one of rice production areas is facing drought due to climate change. Management of rainfed area is needed due to its contribution, in addition to the production of rice, in producing methane as a contributor to greenhouse gas emission. This research aimed to investigate the methane emission status and yield from rainfed rice system with manure and zeolite treatment on the bed system (surjan). The doses of manure were 5, 15 and 30 tons/ha and the zeolite was 1 and 2.5 tons/ha. The result showed that all treatment had no significant effect on daily methane fluxe and grain yield in surjan system. However, the combination of manure at 15 tons/ha with zeolite at 1 ton/ha promoted higher methane emissions (63.43 kg CH4/ha/season). In addition, the combination treatment of manure at 5 tons/ha with zeolite at 2.5 tons/ha contributed to obtain higher grain yield (6.9 tons/ha).
