ABSTRACT
The
fact that ordinary least square (OLS) regression analysis of production
function is constrained by multicolinearity problem is evident. The multicolinearity inherently exists
because in production process certain factors of production are used in
relatively fixed proportion. The
existence of multicolinearity causes such consequences as the estimation of
unknown regression parameters be relatively imprecise and t test leading to the
conclusion that parameter values are not significantly different from zero.
This study aimed to apply the principal component regression procedure as an
alternative way to solve multicollinearity problem on the OLS regression
analysis of production function. By the
principal component regression, it was found that production factor of land,
seed, fertilizer as well as family and hired labour significantly influenced
the rice production. The elasticity of production of those factors showed their existance was in the region II of
production curve. It suggested that the quantity use of those factors should be
increased to get a maximum production of rice. Meanwhile, the quantity of
chemical pesticide should be decreasingly used because of overutilization. This
fact showed by its elasticity of production which was negative so that it was
located in the region III of production curve.

principal component regression, production factor, production elasticity

ABSTRACT
Research of production and efficiency of wetland rice
farming was done in non-irrigated and irrigated land in Gambut and Sungai Tabuk, Banjar Regency, South Kalimantan.
Selection of sites was intentionally set (purposive sampling) with
consideration that the sites was the
center of rice production. The study lasted from Feruary to April 2010. The study aims are to determine the
productivity and efficiency in the use of production factors. To analyze the
factors affecting the production, multiple linear regressions was used,
followed by a test of allocative efficiency. The result of production function analysis showed that the width of land, the amount of urea,
KCL, and ponska, have positive effect on irrigated rice production. Increasing
production can be achieved by adding those factors. Allocative efficiency test
results also showed that the seeds, urea, KCL and ponska were not efficient to
use, yet. As to get maximum production, farmers need to increase the use of those four factors.
Key words: production function, efficiency, rice

ABSTRACT
Minahasa Utara has been known
as center fruits producer in Sulawesi Utara Province for years. However, some
problems is still faced by businessmen in order to develop these commodities,
those are: high fluctuated prices, long gestation period, and land decrease.
Therefore, environment analysis to develop fruits agribusiness that to be local
advantages and have high competitiveness is needed. Exploratory method was used
in this study. Primary data were gathered through questionnaires and
interviews. Samples were taken purposively consist of: 5 government officers
from Agricultural Agency and BP4K of Minahasa Utara, 3 villages chiefs, and 3
agribusinessmen. Analysis used was environment analysis of internal (IFE) and
external factors (EFE). The results showed, the internal factors, which to be
the strengths were: land resource, strategic location, local government
policies, and existence of traders and seed breeders. On contrary, the weakness
factors were: low technological use in post-harvest and product processing,
fruits business management, institutional (farmer groups), and capital access.
While, the external factors those to be opportunity were: promotion program in
national and international events, increase in fruits demand, decentralization,
horticulture development policies from Ministry of Agriculture. Nonetheless,
the treats factors were: fluctuated fruits’ prices, coordination among
government agencies, trade liberalization and globalization, and quality
standards system. This study also suggested that: processing industry should be
developed as well as fruits production and quality. Moreover, the human
resources quality should be increased in terms of management, experiences and
technological mastery.
Key words: environment analysis, internal and external factors, local
superior fruits

ABSTRACT
The
purpose of the research was to analyze the
food expenditure
pattern of paddy farmer’s household in Banjar Regency. The study was conducted in June until
November 2009 in two subdistricts of Banjar Regency of South Kalimantan
Province. Two villages were chosen from each subdistrict namely Kayu Bawang and
Melintang (Gambut Subdistrict), and Penggalaman and Keliling Benteng Ulu (Martapura
Barat Subdistrict). The village choosing was based on the poverty level
(Purposive Sampling). The research was sample survey research by using cross
section data. The samples were taken randomly. The analysis methods used were
descriptive using tables. The result indicated that in Banjar Regency,
the rate
expenditure for
food was
higher than for
non-food. The
rate
of food expenditure
was Rp 6,818.82/capita/day (52.30%),
while for
non-food was Rp 6,219.27/capita/day (47.70%).
There were 32
poor farmer household (35.56%)
and 58
rich farmer household (64.44%).
The result also indicated that the percentage
of food expenditure was
still dominated by the
staple foods (30,54%). The
activity of the food expenditure
pattern development should be put in priority through the diversification
development as the effort to increase the buying capacity.

ABSTRACT
This
study aims to determine the general picture of the implementation of the Direct
Community Assistence-Rural Agribusiness Development (BLM-PUAP) in the Barito
Kuala Regency; Comparison of recipient and non recipient of BLM-PUAP and to
analyze the factors affecting income–of recipient of Direct Community
Assistance-Rural Agribusiness Development (BLM-PUAP). Research was conducted in
Barito Kuala Regency as one of the districts receiving BLM-PUAP in fiscal year
2008 by taking two representatives subdistricts, those are Tabukan and
Mandastana. This study uses survey and interview methods directly through the
technique of structured interviews (using questionnaires) with 100 respondents
(50 BLM-PUAP recipients and 50 non-recipients). The average income of the
BLM-PUAP recipient was Rp 6.799.670, while for non-BLM-PUAP recipients was Rp
4.299,939 and there is a difference in
income between the recipient and non- recipient of BLM-PUAP fund. Income was
simultaneously affected by variable amount of BLM-PUAP funds, own capital, age,
education level, experience, number of family members, and the dummy type of
business. Partially, variables of BLM-PUAP Fund, amount of own capital, age,
experience,and number of family members covered significantly affected the family income.
Keywords: income, BLM-PUAP program
