  • Alternatif Model Pendugaan Stok Gabah/Beras di Penggilingan Padi dan Sub Dolog

Mohamad Chafid, Statistisis Madya pada Pusat Data dan Informasi Pertanian.

Currently, information on total amount of paddy/rice stocks in certain area is not known except by survey. The owner paddy/rice stocks are farmer household, consumer household, rice milling unit, grocer rice, trader rice, restaurant/hotel, industry and Bulog.  On this research, the objective is aimed to develop paddy/rice stocks model for rice milling unit and Bulog. Based on these models, the stocks can be predicted.

Model for suspected stocks of paddy/rice at the rice mill unit in August, affected by the free variables of rice production in March, April, May and July. The results of model analysis in the stock of rice mills shows that stocks in August, is strongly influenced by the production of rice in March. This happens because the month of March is the peak of the rice harvest in Subang Regency, thus providing a significant contribution in expected grain/rice stocks the mill. Model test results indicate this model is feasible with the coefficient of determination corrected for 79.7% (adj-R2 = 79.7%).

Results of analysis showed Arima model can be applied to predict the monthly rice stocks in Sub Dolog. Based on the selection of the best models, models to predict rice stocks next few months at Subang was sub Dolog Arima (2,0,2). Test results for the model parameter estimates Arima (2,0,2) with a test Modified Box-Pierce (Ljung-Box) showed significant value at 95% confidence level.

Family selected  of maize (S1, S2, half sib/HS, full sib/FS) which is hundreds of families to find out of family superior should be used of incomplete block design. The experimental error could be reduce by using of incomplete block design and probably to rejected of hypothesis H0 was highly than complete block design. The simple lattice design with two replication could be used and more accurated to concluded for evaluated family with number of entries k2 (square) or kxl (rectangle).The balanced lattice with two replication is name simple latis design, randomization and data analysis of incomplete block design has been used of alfa lattice, soft ware modification by MST and the last by MSTATC released of Michigan University.

       The experimental just to applied of incomplete block design two replication by 16x16 treatment to evaluated population Pool-2 on drought at KP Muneng Probolinggo has been conducted with model     Yi = μ + βi + τj + αk + εijk + γl + εijkl  and to concluded that 25 families selected with 1,570-2,991 t/ha  yielded and c.v. = 27.0%. The average yield of families selected was higher than control of Bisma

Jeffry E. Sianipar, Parlindungan Silitonga dan S. Hartono, Sriwidodo, Dwidjono. Sekretariat Badan Litbang Pertanian - Jakarta dan Dosen Ekonomi Pertanian UGM - Yogyakarta.

Paddy production and productivity in Manokwari increased 6,5% inyear of 2006 - 2008. The growth of it was lower than growth of national productivity, namely national productivity was 4.8 ton/ha while paddy productivity in Manokwari was 3.75 ton/ha. Research aimed to analyse the influencing factors to paddy farm production and farm house-hold consumption. Research has been done in Prafi and Masni District, Manokwari Regency. Production was analysed by Cobb-Douglass production function and estimated by Ordinary Least Square (OLS). Meanwhile demand consumption function was estimated using Seemingly Unrelated Regression (SUR). Research of result showed that usage of seed, availibility of out side family labour, urea, NPK, PPC fertilizer, and farm intensification influencing paddy production. While farm household consumption was influenced by price of goods, farm income changing and improving farming by farm intensification.

  • Analisis Kinerja Pemasaran Jeruk Keprok Soe di Kabupaten Timor Tengah Selatan Nusa Tenggara Timur
Yusuf, Masniah dan Masyhuri, Irham, Jangkung Handoyo Mulyo. BPTP NTT dan Dosen Ekonomi Pertanian UGM - Yogyakarta. 

Soe tangerine is one of the leading national commodity East. Market opportunities still wide open because the development of acreage, production and productivity since 2002 continue to rise. The purpose of research, are: (1) knowing marketing channels, (2) to analyze the marketing margin, and (3) analyze the efficiency of marketing, the elasticity of price transmission and market integration. Research approach using suvei, Meret conducted in the month - December 2009. Results showed: There are four marketing chain tangerine soe, namely: (1) farmer - middlemen - retailer - consumer end, (2) farmer - retailer - consumer end, (3) farmer - collector - end consumers, and (4) farmer - the final consumer. Margin seen on the channel I was Rp 2146.75 per kg for traders and Rp 4424.19 per kg to retailers. Marketing channel II for USD 2738.55 per kilogram, and the margin for the third marketing channel for USD 5547.10 per kg. The average technical efficiency index for each of the marketing channels are: Channel I amounted to 57.25; channel II, IV lines at 83.19 and 35.26. While the average index of economic efficiency channel I 0.12; channel II and channel III 0.16 for 1.38. III marketing channels with the lowest technical efficiency index and efficiency index is the largest ekonomsi more efficient marketing channel. Elasticity of Price Transmission (ET) is approximately 1.060 (Et = 1) means that the sensitivity changes in relative prices at farm level with changes in relative prices at the level traders. The correlation coefficient (b1) = 0.043, meaning there is no integration (integration) are perfectly between the market prices at the farm gate to the market at the consumer level, so to say the market is not efficient.

  • Revitalisasi Radio Pertanian Ciawi (RPC) Sebagai Pusat Informasi Pembangunan Pertanian
Retno Sri Hartati Mulyandari, Amiruddin Saleh dan Dadan, Pustaka, IPB - Bogor dan PPMKP - Ciawi. 

Information Center for Rural Development (Pusat informasi pembangunan perdesaan-PIPP) is one of the institutions for developing the network collaboration with government institutions, private, and Non Government Organizations related in rural and agricultural development.  PIPP is expected to  develop the social networking within target audiences, especially for productive message intentions enforcement.    It is such as appropriate knowledge information that has been translated from science institutions source. As a radio broadcasting that focusing on educated information services for communities, farmers especially, Radio Pertanian Ciawi (RPC) that was developed by Agricultural Management and Leadership Training Center, Indonesian Agency for Human Resource Development, Ministry of Agricultural (Pusat Pelatihan Manajemen dan Kepemimpinan  Pertanian, Badan SDM, Deptan) is not pure as a commercial radio broadcasting. RPC revitalization is needed for facing the RPC development as an ideal PIPP and multifunctional for supporting the each aspects of agribusiness chain. This revitalization activities are: a) Proposing the RPC as a leader or information source of improving the human resource development of farmers community and radio broadcast legality application (Ijin Siaran Radio – ISR) to Dirjen Postel; b) Developing the PIPP-RPC management through organization completion and human resource development professionally; c) Revitalizing the RPC services through: providing information and promoting products, documenting and managing the agricultural information and other related information supporting the agribusiness activities, facilitating the interpersonal approach for information access and technical consultation, and improving the agribusiness player capabilities in supporting the agricultural information access and management both manually and information technology application.
