Abstract

Collection and selection are important steps in a breeding activity series. The purpose of this research is to produce new superior varieties of sweet corn, chilli and cowpea, as this research is also a bridge between researchers/lecturers (seed producer) and farmers (seed users). This research was conducted in Gunung Gede experimental garden, IPB Diploma Programs, commenced from August to December 2010. The genetic materials used are 1 (one) genotype of corn, 10 genotypes of cowpea, and 12 genotypes of chilli. The plant materials are strains produced by the Plant Breeding and Genetics Laboratory of Agronomy and Horticulture Department, IPB. The experiment was done in Randomized Block Complete Design, one factor is genotype. The negative and positive selection was applied on sweet corn selection, while the index selection was applied on chilli and cowpea. Selection on corn (with 20% of selection proportion) produced 30 best plants. This step can be used as a startup to get the next population (with upturned genetics) to be better. The 5002046 is the best chilli genotype; meanwhile Cilibende, Kencana, K7 and Majalengka are the best cowpea genotypes. Selected chilli and cowpea genotypes are candidat lines for good seed production.Keywords: corn, cowpea, chili, seed, selection.

Abstract

This research was conducted to study the effect of probiotic bacteria application through artificial feed on growth performance of tiger shrimp. The research was carried out for 42 days with four treatments and three replications, those were control, SKT-b (feed + SKT-b probiotic), 1 UB (feed + 1 UB probiotic) and commercial (feed + commercial probiotic). Feed and probiotic bacteria were mixed in ratio of 3:1 (weight : volume) by adding 3 % of white egg as a binder.  Then the test feed was analyzed by proximate analyses and compared by using control feed. Tiger shrimps with initial weight of 0.04 ± 0.005 g were reared in 50 cm x 40 cm  x 40 cm aquaria at the density of 15 shrimps per aquarium.  Feeding was carried out four times a day at 08.00, 12.00, 16.00, and 22.00. The weight of tiger shrimp were observed once every 2 weeks, whereas the water quality and the total abundance of bacteria in media were monitored at the beginning, middle and end of the research.The result showed that theadministration of the probiotic bacteria through artificial feed produced better growth rate than control. Application of 1 UB probiotic gave the best results by producing 9.03% growth rate and 1.35feed conversion ratio. Whereas, survival rates for all treatments were not significantly different from the range of values between 91.11% - 97.78%.Keywords: probiotic bacteria, feed, tiger shrimp

Abstract

The study was aimed to examine the storage effect of rennet extracted from abomasum of local sheep on the texture and organoleptic qualities of cheese including color, flavor, salty taste, and bitter taste. Ten samples of crude rennet extract were divided into two groups which each five samples were stored for 2 weeks and 24 weeks  respectively. The rennet extract was then used as milk clotting agent in cheese making process. Streptococcus thermophilus and Lactobacillus bulgaricus were used as starter in those processes. The fresh cheese was coated with beeswax and ripened for 20 days in refrigerator. The ripened cheese was analyzed for the quality. The texture was analyzed by using warner blatzer shear (INSTRON®) and the data were evaluated with completely randomized design (CRD). The result showed that both time storage of rennet extract were not significantly influence on cheese texture (P<0,05). The organoleptic tests of color, flavor, salty taste, and bitter taste were rated by 25 panelists and then the data were analyzed with Friedman test. The time storage of rennet extract resulted variation on organoleptic quality of cheese.  Descriptive statistical analyses provided information that each panelist has varied preferences on cheese samples. It can be concluded that the storage of rennet extract had no significantly influence on the texture of cheese and provided variation  on organoleptic test. Keywords: storage, rennet extract, cheese, organoleptic test

Abstract

IPB Diploma Program has alumni that are broadly spread throughout Indonesia. Tracer study is always conducted progressively each year. Other methods conducted include questionaire via post, email, mailing list, graduation ceremony, alumni meeting, etc. By evaluating tracer study, some innovations are needed to increase its activities. Regarding the advancement of web based technology and internet media that has gone significant in Indonesia, one innovation for tracer study is a website facility which can be accessed by alumni, assumed that all alumni have internet access. IPB Diploma Program Tracer Study Information System is built on the basis of web technology. This system is aimed to increase data collectivity and gives out information, in form of report with default format prepared by IPB Diploma Program. This research yields an IPB Diploma Program Tracer Study Information System which already helps alumni and the data collection of user satisfaction. IPB Diploma Program Tracer Study Information System has a feature to show report which makes alumni information and user satisfaction data to be easily obtained. The information shown is in the form of graphic and tabular data. On the other hand, this system is also equipped with alumni searching facility to track whether an alumni has already participated in tracer study activity.Keyword : Information system, tracer study, website facility

Abstract

E-learning method provides the ease and smoothness of the teaching-learning process for both students and lecturers. With e-learning methods, teachers can increase the intensity of interactive communication with students outside of official class hours. E-learning methods provide flexibility to the faculty to provide access to students to gain scientific references related to the course that may not be obtained during the hours of lecture and lab activities. These references may be scientific papers, popular articles or electronic journals.   This would be particularly useful for students, because in addition to strengthening the understanding of students for each subject of the course, a reference of the international journals will greatly help to expand the students’knowledge, as well as improve their English. So hopefully in the future, IPB Diploma graduates, especially those who earn Programming Language course, will have high competitiveness in the global competition which is increasingly filled by graduates of foreign universities.Keyword : e-learning, online, course, learning methods.

Abstract

The implementation of conventional accounting system is based on the accounting records which are done manually (paper work). In contrast, the implementation of computer-based accounting system is an impact of the development of science and technology. Therefore, the manually accounting records can be replaced by computersin terms of data processing of daily transactions to financial reports. The purposes of this research are firstly to determine the implementation of conventional accounting system at UD. Mekarsari.  Secondly is to determine the implementation of computer-based accounting system in PD. Cimanggu Jaya. Lastly is to compare  those two accounting systems which have been applied to the two companies. The difference of those two models of accounting system can be seen from the output of the accounting records. All variables or sub systems that run on those two trading companies with different accounting recording system is the study of assessment of the implementation between conventional accounting system and computer accounting systems so that two accounting systems can be compared. Last stepistoprovidere commendations for improvement in the implementation ofthe accounting system for more efficiency and effectiveness when applied in the trading companies. Based on the results and discussion, it can be summarized as follows: 1). The application of conventional accounting systems at UD. Mekar Sari is still simple.   2). The application of computer-based accounting system at PD. Cimanggu Jaya has formed separate functions, all transactions are recorded in the printed serial numbered transaction receipt, and has done journal recording to generate financial reports using computer applications ie Microsoft Office Excel. 3). The comparison between the conventional accounting system and computer-based accounting system on timber commodity trading company shows that the conventional accounting system is more simple, their functions have no optimal performance, and the application of internal control is still lacking, so the company’s financial statements has not been realized.Keyword : Accounting System,Conventional Accounting System, Computer Based Accounting System
