Abstract

Parthenocarpy on plant can be produced through a number of approaches, for example via application of gibberellin on the flowers of plant. The aim of this experiment was to investigate the production of parthenocarpy on the eggplant via application of various gibberellin concentrations. This experiment was conducted on the farmer’s land in Lasoani village, Palu city, Central Sulawesi,from December 2014 to April 2015. This experiment used Randomized Block Design with treatments tested namely concentration of gibberellin consisted of four levels, including without gibberellin application, application of gibberellin with 0.1%; 0.2% and 0.3% per flower. Each treatment used five replications, and therefore there were 20 experimental units used.Furthermore, each experimental unit utilized two flowers and there were 40 flowers used as experimental object. Variables observed consisted of weight, length and diameter of eggplant fruits as well as the number of seeds formed. Results of this experiment indicated that the application of gibberellin had a significant effect on the parthenocarpy of eggplants. Eggplants applied with gibberellin at the concentrations of 0.1% - 0.3% resulted in parthenocarpy, but weight, length and diameter per eggplant only ranged from 32.76 g to 53.60 g; 6.94 cm to 9.30 cm; and 3.30 cm to 4.60 cm, respectively; whilst eggplants formed without application of gibberellin produced up to 221 seeds with weight, length and diameter per eggplant reached 162.32 g; 21.20 cm; and 5.12 cm, respectively.

Abstract

         The fresh meat is easy to damage due to the change of chemical and microbiological contamination. This study aims to determine the quality of microbiological and organoleptic quality jerky laying ducks curing rejects at various times and concentrations of salt. The Experiments used completely randomized factorial design with two factors: the first factor, the time of curing (C) consists of 15 hours (C1), 20 hours (C2), 25 hours (C3) and 30 hours (C4). The second factor was the concentration of salt (B) consisting of: 5% (G1) and 10% (G2). Each treatment was repeated 2 times therefore there are 16 units experimental treatment. Variables observed included: 1) Test microbiology (TPC) and 2) the organoleptic test. The results showed that the interaction of treatment time and the salt concentration significantly affected to the appearance, aroma and taste, while the color and quality of microbiological have no real effect. Microbiological quality of the treatment time curing for 30 hours (C4) was not significantly different  on the total microbial jerky laying ducks culled but gave the lowest total of microbial namely 1'5 x106 compared to another treatments. Organoleptic quality test showed that the best combination of treatment was that the curing time for 25 hours with the salt concentration 10% (C3G2) on the appearance, aroma, color and flavor with the average value 5 (like category).

Abstract

Tilapia has a high tolerance to salinity waters. This study aims to assess the growth and survival of tilapia reared at salinity. Assessing the optimal salinity for the growth and survival of tilapia fish. This study will use a completely randomized design (CRD). Completely randomized design to be used consists of 4 levels of treatment with each of 4 replicates ie Treatment A: Maintenance of tilapia in medium salinity 0 ppt, Treatment B: Maintenance of tilapia in the media with a salinity of 10 ppt, Treatment C: Maintenance fish indigo in media with 20 ppt salinity, treatment D: Maintenance of tilapia in media with 30 ppt salinity The variables measured were daily growth rate and survival of tilapia reared at salinity media The results showed that the growth of tilapia is affected by salinity, The highest absolute growth value was obtained at a salinity of 20 ppt with an average of 2.68 grams, then followed at a salinity of 30 ppt with an average of 2.35 grams and a salinity of 10 ppt with an average of 2.31 grams and the best growth rate achieved at a salinity of 20 ppt is 26,48%. Tilapia fish survival was not significantly different in the four treatments. This suggests that the increase in salinity from 0 ppt - 30 ppt does not affect the survival of tilapia fish

Abstract

This research aimed to: 1) describe the structure of plankton community in the Gulf of Palu; 2) explain the relation between the physical-chemical waters conditions and the plankton community in the Gulf of Palu; 3) producea biological learning media in form of book as a learning resource. This research has been employed a quantitative descriptive method by using field survey and laboratory. The research samples have been collected three times through a sampling technique by using the plankton net. The research’s results have found 49 types of plankton which consist of 27 types of phytoplankton and 22 types of zooplankton from various taxonomic categories. The plankton abundance is around 2.818 to 4.072 cell per liter. The value of plankton’s biodiversity index is 2.81 to 3.15 which shows that the community establishment is good (stable) and the uniformity index located at 0.98 to 0.99. Based on achieved value, which is in range of 0,040 to 0,065, the dominance value index has also shown that there is no dominant type. From the Morisita’s index calculation that intended to determine the distribution a pattern of plankton types, this research has found that around of 78 percent of phytoplankton is uniform and 22 percent is regular in their distribution patterns. Meanwhile, for the zooplankton the distribution pattern is 86 in form of uniform distribution and 14 percent in a group formation. The result of assessment produced by this Knowing Plankton’s monograph, both its content and design, has finally declared “feasible” with the percentage of 95.55 percent.

Abstract

The aim of this study is to identify VSD  attacks  to cocoa crop in three villages in Palolo. b.analize  the way of VSD   infecting  cocoa crop in three villages, in  Palolo, Sigi. c.how to cut  the attack and control the damage caused by VSD to cocoa in three villages in Palolo. This study using identification method. The  research method  that is conducted through observation of the leaves, twigs and branches of the cocoa plant which suspect  attacked  by VSD in the field and observation in laboratory to ensure that the attack VSD on cocoa in the three villages in Palolo actually happened , as well as focusing on actual problems of the development of  VSD. The research was conducted in three villages names  Ampera, berdikari  and  Rejeki village in Palolo. Determination of the location of the research done on purpose (purposive method), with the consideration that all three of the village is the center of  development of  cocoa  production in  Palolo.  This research was conducted for three months from January to April 2015  and then continued  by observing VSD in the laboratory of pest and disease Agriculture faculty, Tadulako University. VSD has been  informed  attacking   almost all the province which producing cocoa   in Indonesia. In 2000, there were VSD attacks reaches 6000 ha with yield losses  Rp 405 643 680 000 / year.  The number of the attack until May 2001 reached 70 000 ha with a loss of billions  rupiah (Ditjenbun, 2007). The observation  result  like contained  in Tabel 1 show that in average the intensity  attacks of VSD  from the research site showed that  cocoa  in Berdikari  has the highest VSD attack it is 16.9%, on the contrary VSD attack  in Ampera  and Rejeki are low attack each of  them  12 , 5% and 12.1%. This shows that in all three villages have been found the attack of VSD as seen in the field, where the characteristic of  attack ,the leaves infected  of VSD changes the color  to yellow with green patches on the surface of the leaves, and the leaves will eventually fall. In the former  leaves holder  which is affected by VSD will appear visible three point brown indicates that the plant has been attacked by VSD, meanwhile on the twig attacked, if observed in detail and touched with fingers, it would seem that the surface of twig is uneven  because it has been Swelling occurs on the surface, so that within a certain time the branch would dry up and will seem toothless, this happens because the VSD disease has progressed on the xylem and hinder the process of transformation of food to other plant tissues. These events will cause significant changes in plants, from healthy plants become dry due to the intake of food that goes into the xylem become obstructed. With the special mark left by VSD on branches and twigs of cocoa plants in three villages can be assumed that in  Palolo, there has been a VSD attacks caused by fungi Oncobasidium theobromae (Basidiomycetes).
