Abstract

The objectives of this study were to identify and evaluate diet composition and feeding strategy of Gobiid fishes in Pabean Bay, Indramayu. Fishes were collected monthly using gill nets, shrimp nets and fixed trap nets from April 2016-March 2017. Diet composition and feeding strategy were analyzed by IRI (Index of Relative Importance) and modification of the graphical Costello method, respectively. Nine species of Gobiidae were captured during the study period, namely Acentrogobius caninus (with total body length range 46-115 mm), Acentrogobius cyanomos (49-108 mm), Boleophthalmus boddarti (95-189 mm), Glossogobius aureus (70-210 mm), Oxyurichthys tentacularis (88-130 mm), Parapocryptes serperaster (112-198 mm), Paratrypauchen microcephalus (100-150 mm), Pseudapocryptes elongatus (88-190 mm), and Taenioides cirratus (160 mm). According to the diet analysis, A. caninus, A. cyanomos, and G. aureus were grouped into crustacivore, while the B. boddarti, P. serperaster, P. microcephalus, and P. elongatus were categorized as phytobenthic feeder. A. caninus, G. aureus, and A. cyanomos exhibited a specialist feeding strategy with the main food was Metapenaeus sp., Metapenaeus sp. and Acetes sp., respectively. B. boddarti, P. serperaster, P. microcephalus, P. elongates displayed a generalized feeding strategy. This research showed that Gobiid fishes occupy different trophic levels and play an important ecological role in Pabean Bay.

Abstract

In recent years there has been a decrease in Cipaniis springs, indicating the declining ecological conditions of the area surrounding the spring. The compensation fund provided by Kota Cirebon to Kuningan Regency in the framework of payment for environmental services cooperation since 2004 has not provided significant benefits for Cirebon City, the surrounding community, and the environment. This study aims to evaluate the allocation and use of compensation funds and its benefits to the city of Cirebon, society, and the environment. Gap analysis is used to evaluate the allocation and use of compensation funds, as well as descriptive analysis on see the benefits of compensation funds for PDAM of Cirebon City, communities, and the environment. In 2016 the compensation fund paid is IDR 2.9 billion, of which only 16.23% is allocated for conservation activities, 1.53% for the villages around the springs and the remaining 82.3% for the Regional Government of Kuningan Regency. The compensation fund for the payment of environmental services has not been utilized properly, so the benefits received by PDAM of Cirebon City, society, and environment are still very low.

Abstract

Cattle and buffaloes have economic value as a source of protein and draught power. The people of Sulawesi also use buffalo in various custom and religious activities. Infections by Trematodes may disrupt livestock productivity. In Indonesia, endemic Schistosomiasis can only be found in Central Sulawesi, Indonesia (Lindu, Napu, and Bada Valleys). There is no data on the status of Trematode infection in cattle and buffalo animals in the area. The study was conducted using a cross-sectional design to measure the prevalence of Trematodosis in cattle and buffalo around the endemic areas of Schistosomiasis in July-November 2016. A total of 261 stool samples consisting of 173 cattle and 88 buffaloes from 7 villages (Anca, Bewa, Mount Gintu, Sedoa, Wangga, Watumaeta, and Wuasa Villages) were collected and stored at 2-8 °C until further analysis. The Danish Bilharziasis Laboratory method was chosen to quantify the infection by trematodes. The prevalence of the overall trematodosis of this study was 85.06%. The prevalence of Trematodosis in buffalo was higher than in cattle and differed statistically (P<0.05). The highest prevalence was Paramphistomiasis (75.48%), followed by Fascioliasis (67.05%) and Schistosomiasis japonica (30.27%). The trematodosis prevalence of each village also varied and differed statistically (P<0.05). Intensites of infection of mild, moderate, and severe infections were reported in this study. Mixed infections by two even three species of trematodes were reported in this study. Two newly endemic Schistosomiasis villages are reported, namely Bewa Village and Gunung Gintu. The results of this study are used as a basis for controlling Trematodosis in large ruminants in endemic areas especially with zoonotic potential.

Abstract

Papayas as a climacteric fruit are commontly harvested and distributed in an unripe state with various of maturities. Ripening is required before papaya ready for consumption. The objectives of this research were to analyze the response of artificial ripening treatment for papaya in order to perform the best marketing schedule. This study was started by harvesting, sorting, cleaning, hot water treatment, and transportation simulation similar to 90.44 km, storage in refrigerator at 15 °C, artificial ripening treatment and storage at room temperature. Physical quality parameters measured consisted of weight loss, color, firmness, and total soluble solid. Artifial ripening using ethephon will accelerate the maturation of papaya. Papaya with maturity level of 60% (yellow tinge) that stored at 15 °C for 7 days was found still not ready to be consumed as a table fruit, and it was still necessary to artificially ripening process. Artificial ripening using ethephon of 250 and 750 ppm did not significantly affect the fruit color, hardness, and total soluble solids. This papaya could be consumed after 2 days of ripening and reached the optimum conditions for consumption after 4 days, with a possibility of shelf life for 6 days at room temperature. The best artificial ripening treatment for papaya that had been stored 14 days at 15 °C was by using 250 ppm of ethephon. The use of 250 ppm ethephon would make the best visually and smoothly yellow color of papaya?s peel surface.

Abstract

Rice demand in Indonesia increases every year so it makes the big gap between production and consumption of rice. Excess demand is covered by rice import which causes domestic rice price responds the global rice price movements that harm both producers and consumers. So, the policy instruments that could reduce dependence on rice import and can provide benefits to producers and consumers of rice is very needed. The objectives of this study were to analyze the impact of rice policy on rice market and the welfare of rice producers and consumers. This study uses annual time series data and simultaneous equations model with two stages least squares method. The analysis showed that rice policy changes can influence condition of Indonesia?s rice market and that the increase in Government Purchase Price (HPP), agricultural credit, and fertilizer subsidy can improve the welfare of the producers and consumers.

Abstract

Void space in the bean layers will lead to the occurrence of non-fully interacted radiation (NFIR) affecting the reproducibility of NIRS measurements. Void space in addition to being affected by particle size is also influenced by the number/thickness of the bean layers. The objective of this study was to analyze the effect of number of bean layer variation on prediction accuracy of caffeine, chlorogenic acid and trigonelline in Bondowoso green Arabica coffee beans by NIR Spectroscopy (NIRS). The study was conducted using three kind of layers, i.e. 3, 4, and 5 layers, with 100 samples each. Samples were measured by FT-NIR spectrometer in wavelength of 1.000-2.500 nm. The pretreatment method used were second derivative (dg2), the combination of first derivative (dg1) and Multiplicative Scatter Correction (MSC), and the combination of dg2 and MSC, while calibration method used was Partial Least Square (PLS). The results shows that the accuracy of 5 layers was better than 3 or 4 layers. The best calibration and validation for caffeine was obtained by dg2 pretreatment and 6 factors of PLS (r = 0.99; SEC = 0.01%; SEP = 0.01%; and RPD = 5.40), for chlorogenic acid was by dg2 pretreatment and 5 factors of PLS (r = 0.99; SEC = 0.09%; SEP = 0.09%; and RPD = 4.76), whereas for trigonelline was by combination of (dg2, MSC) and 5 factors of PLS (r = 0.99; SEC = 0.01%; SEP = 0.01%; and RPD = 4.86). Therefore, the 5 layers can be used as a reference in NIRS measurement of coffee beans.

Abstract

The aims of this study were to analyze the effect of environmental factors (age of bull, season of collection and frequency of ejaculation) and estimate the repeatability on semen quality of ongole grade bulls. Semen data were collected from Singosari National Artificial Insemination Centre, in Malang District, East Java Province, Indonesia. A total of 1.020 ejaculates collected from three Ongole grade cattle from 2012-2016 were analyzed. Data were analyzed by restricted maximum likelihood (REML) method using the mixed model including the random effect of bull and the fixed effects of age of bull, season of collection, and ejaculate number. The results showed that age of bull and ejaculate number significantly affected all studied variables (P<0.01). Season only affected to sperm motility (P<0.01). Repeatability estimates of semen volume, sperm concentration, total number of sperm and sperm motility were 0.48; 0.42; 0.28; and 0.01, respectively. It was concluded that the age of the bull and frequency of ejaculation significantly affected semen quality of Ongole grade cattle. Repeatabilities for semen quality were low, moderate and high.

Abstract

One effort to increase domestic sugar production is through the extension of sugarcane growing area outside Java island. The status of sugarcane disease outside Java, particularly those caused by virus(es), has not been evaluated yet; where virus diseases are able to decrease sugarcane productivity. Therefore, the aim of this research was to identify the sugarcane major viruses and their distributions in Lampung and South Sulawesi. Field survey and leaf sampling was collected from Lampung Tengah District, in Lampung Province and three districts in South Sulawesi Province i.e., Bone, Gowa, and Takalar. Virus detection was performed by reverse transcription-polymerase chain reaction (RT-PCR) method using specific primers for Sugarcane mosaic virus (SCMV), Sugarcane streak mosaic virus (SCSMV), and Sugarcane yellow leaf virus (SCYLV). Results indicated that symptoms variation was observed in the field. The highest disease incidence and severity was found in Lampung, i.e. 100% and 61.67-71.67%, respectively; whereas the lowest disease incidence and severity was found in Takalar, i.e. 5-70% and 5-45%, respectively. The disease incidence and severity of viral diseases tend to be low in dry and low rain fall conditions. This information might be helpful for the extensification program of sugarcane development in supporting the sugar self-sufficiency program. Keywords: disease incidence, disease severity, reverse transcription-polymerase chain reaction, sugar self-sufficiency

Abstract

The research to improve the growth, production, and seed quality of Jack Bean (Canavalia ensiformis L.) through pruning, which was carried out from May to October 2016 in Purwasari Village, Dramaga, Bogor Regency and continued by seed testing at the Seed Testing Laboratory, Bogor Agricultural University in December 2016. The research was designed in a randomized block design (RBD) with eight treatment of stem and branch pruning and one treatment without pruning as a control, i.e. without pruning of branches and stems (P1), pruning on the 10th stem nodes (P2 ), pruning on the 11th stem nodes (P3), pruning on the 5th branch nodes (P4), pruning on the five branch nodes and the 10th stem nodes (P5), pruning on the 5th branch nodes and stem nodes to -11 (P6), pruning on the 6th branch nodes (P7), pruning on the 6th branch nodes and 10th stem nodes (P8), and pruning on the 6th branch nodes and 11th stem nodes (P9). The results showed that pruning affected some of the results of the study, but was not able to increase the production of Jack Bean. Pruning treatment on the 5th branch nodes and 10th stem nodes (P5) produced the highest seed production (3.4 tons ha-1), the physical quality of the seeds produced was classified as moderate with a weight of 1000 seeds between 1273.3-1291.7 g. The physiological quality of the seed is moderate with maximum growth potential 84.0-90.7%, germination percentage 73.3-82.7%, germination speed 9.1-116.1% / etmal, germination uniformity 40.0-49 , 3% and vigor index of 14.0-20.0%.

Abstract

Clove is an important commodity in Indonesia and it is used as a main material for cigarettes. Clove propagation can be conducted by generative method, but this method takes a long time to produce a considerable number of seedlings. To overcome such problem, it can be applied a tissue culture technique. An effort has been conducted to induce calli from sliced clove leaves and performed at Plant Biotechnology Laboratory, Faculty of Agriculture, Tadulako University from June-November 2016. The aim of this experiment was to determine the most suitable type and concentration of auxins for callus induction of sliced clove leaves via in vitro culture. This experiment used a Completely Randomized Design with six treatments, namely 0.25 ppm 2.4-D; 0.50 ppm 2.4-D; 0.75 ppm 2.4-D; 0.25 ppm NAA; 0.50 ppm NAA; and 0.75 ppm NAA. Parameters observed consisted of the speed or time of appearance, the percentage, color, and texture of calli. Data were analyzed by using analysis of variance and differences between mean treatments were determined by Duncan Multiple Range Test at 5% level. The results of this experiment indicated that the type and concentration of auxin most suitable for callus induction of sliced clove leaves was culture medium supplemented with 0.75 ppm 2.4-D. In such medium composition, it was obtained the quickest callus formation, namely average 4.22 WAC with the percentage of callus formation was up to 100%. In general, the colors of calli were white, yellowish white, and brown; with the textures of formed calli were soft, compact, and intermediat. Keywords: callus formation, clove, growth hormone, tissue culture
