  • Penggunaan Analysis Multifase dalam Karakterisasi Produksi Telur - The Use of Multiphase Analysis  in Egg Production Characterisation

L. Hardi Prasetyo

An intensive duck farming requires a production system with a high efficiency. One way of achieving high efficiency is by including only individuals with high productivity and consistency of production. A method of analysing individual egg production using a multiphasic approach with a mathematical model has been developed and successfully used in chicken and quails. However, its application in ducks is still not known and needs to be studied whether it can be used to characterize individual egg production. For this purpose, 20 Mojosari ducks at 9 - 10 month old were observed for a month, especially on the time of oviposition daily. The relationship between cumulative number of eggs and time of oviposition was analysed while considering lag and delay period in the production cycle. The results show that the estimates of lag range between -0.285 and 1.762 hours, and the average estimates of delay is 29.144 hours. The application of this method on ducks has not been able to detect the relationships between lag, delay, and the number of clutches. This is mainly due to large variation in time of oviposition in each individual. It can be concluded that this model can be applied.

  • Aplikasi Indeks  Tornqvist-Theil dalam Pengukuran Pertumbuhan Produktivitas Masukan Parsial dan Total-  The  Application  of Tornqvist-Theil Index in  Measuring  Partial  and Total  Factor Productivity

The  Application  of Tornqvist-Theil Index in  Measuring  Partial  and Total  Factor Productivity: A Case Study of Irrigated Rice Farming in  West Java.  Theoretically,  productivity is  defined as  the  level  of  output produced  per unit of input used in the production process. It is commonly measured  as  the  ratio  of  output to  a  single  input,  such  as  labor productivity, capital  productivity, or land productivity  (yield).  These measurement  are  simply  partial productivity concept.  The  total  factor productivity (TFP), on the other hand, is the generalization of the partial productivity concept.  TFP is measured as the ratio of aggregate outputs to the aggregate inputs, in value terms. This study is using  Tornqvist-Theil index  to  measure  both partial and total  factor  productivity  of  rice production in Northern Coast of West Java. The results of this study showed that  the partial factor productivity of almost all inputs, (except seed in 1980-88  and  labor  in all periods), exhibited a  negative  growth.  These results imply that the positive growth of output was much slower than  that of  inputs. If there is a negative growth of output, the decline in  output was  faster  than that of inputs.  The TFP, on the other hand, grew  by 30 percent  from 1980 to 1988, or it grew at a rate of 3.3 percent/year.  From 1988  to  1992, the TFP grew by -18 percent (-4.8 percent/year).  The  high growth of TFP from 1980 to 1988 have been caused by a significant  increase in yield due to an improvement in technology adoption from Insus in 1980 to Supra Insus in 1988.  In contrast, a sharp decline in TFP from 1988 to 1992 was mainly due to a significant decline in yield.

  • Penggunaan Program Linier pada Survei Karakterisasi Lahan Sawah Tadah Hujan, Sulawesi Selatan - Utilizing Linear Programming in Characterisation Survey at Lowland of Rainfed Area, Sulawesi Selatan

Jermia Limbongan

Utilizing  linear programming in characterisation survey at lowland of rainfed area, Takalar, Sulawesi Selatan was carried out in June, 1993.  Data was analized with LP 88 to determine resource allocations . The result of the research showed that Linear Programming can give a good information about optimum number of resource in the low land of rainfed area.  Bisides of that, optimum profit, optimum Cropping Pattern, optimum price for input and output also be find out. Decision maker can be Linear Programming information to make decision from now and future.  Also, we find out the tolerant limit of profit, price and amount of input and output.

  • Analisis Korelasi "Rank Spearman" dan "Konkordansi Kendall" dalam Penilaian Berkomunikasi antara Peneliti dan Penyuluh (Kasus Persepsi untuk Komoditas Pangan di Sulawesi Selatan) - Correlation analysis of "Rank Spearman and Concordansi Kendall" in communication of Researcher and Extensionist (Case of Perseption on Food Crops in South Sulawesi). 


Correlation analysis of "Rank Spearman and Concordansi Kendall" in communication of Researcher and Extensionist (Case of Perseption on Food Crops in South Sulawesi). The objektive of analysis is to find out the correlation of researcher‑ extensionist to explain the interrelated of relationship and ranking value in constrain of communication. The sample size is researcher is in RIMC (Research Institute for Maize and Other Cereals) Maros, and extensionist which is consentrate of food crops. The result correlation value is 0.88‑0.97 and could be interpretation that all variable be taken (old, education, service period, cooperation trial activities, communication frequently, and respons in communication system) is the same idea to find out the issues of constrain to increase of communication system. The high ranking to be solution of constrain is communication activities is very less, the location activities is far, less ability to communicaticated, cost and facility is less, different institution, motivation in collaborate is less, and different education level.

  • Mengenal Internet sebagai Jaringan Informasi Global - Internet as a Global Information Network

Nurheru dan Cece Suhara

Internet was initially established in the USA as a military information network. This network system was then used bye some universities for research and education information tool. The development of telecommunication and information technologies urged the internet to develop very fastly. The turning up of commercial provider resulted the wider internet serve almost in all living aspects. Internet facilities commonly used are World Wide Web (WWW), File Transfer Protocole (FTP), Telnet and Electronic Mail (E-mail). WWW is the favoured internet facilities, where the users may obtain or present the information (research, education, promotion, etc.) as text, figures, graphics, or even sound. The users may use an FTP server to up-load or down-load files from the server. A lot of computer programs or data base can be accessed from FTP server. Telnet is a two-way communication program application so that someone may communicate with their organization. E-mail is another internet facility which is also widely used. Using e-mail is relatively cheaper and extremely faster than conventional mail.
