Abstract

The aim of the research was to probe farmer’s knowledge, attitude and action on the use of pesticide and its impact on the health of the farmers and the population of various organisms.  The research was conducted in the production center of shallot at Nganjuk regency of East Java Province from March to August 2002 and used the survey method.  The number of respondents was 192 farmers selected based on the Stratified Sampling method at six villages from three sub-districts.  The results showed that the SLPHT farmers had a high level of attitude and knowledge on the use of pesticide whereas the non-SLPHT farmers only had low to moderate level of both.  However, the farmer’s attitude and knowledge were not implemented when they applied the pesticide on their crop.  Harmful effects of the pesticide misuse have degraded the farmer health with symptoms such as unconscious, blindness and also acetilcollin enzyme disorder.  The population of local organisms was also reduced.  In conclusion, the farmers had overlooked their own knowledge and attitude when pesticides were applied in the field, consequently the farmers’ health were at risk.

Abstract

The objectives of the research were to increase the use of arenga starch and to achieve an optimal processing method of instant starch noodle made of arenga starch. In the research, the instant starch noodle was made using porridge methods. The methods of making instant starch noodle porridge including determination of starch/water ratio, duration of cooking, and optimal aging time. The starch/water ratio and duration of cooking was established based on inter-molecule binding freedom level (gelatinization and retro gradation) with a minimal score of 80% according to instant noodle requirement (SNI 01-3551-1994). While, the determination of aging time was based on physicochemical properties of instant starch noodle produced. The physicochemical properties included water content, inter-molecule binding freedom level, and cooking speed, cooking loss, tensile strength, elongation, texture and white level. The results of the research indicated that the best porridge method was done with starch/water ratio of 1:1.5 (v/v), cooking duration of 12 minute, and aging of 60 minute. Physicochemical properties of instant starch noodle porridge using such method resulting in water content of 7.62%, inter molecule binding freedom level of 82.70%, cooking speed of 2.42 minute, cooking loss of 6.15%, tensile strength of 0.018 MPa, elongation of 7.44%, texture of 10.27 N and white level of 76.30%.

Abstract

Land use changes from forest to agricultural farms have been incessantly occurring in Indonesia. This condition will have harmful effects on nature equilibrium if uncontrolled. Forest can effectively absorbed carbon, in contrast deforestation will result in the release of carbon dioxide (CO2) to the atmosphere. The research results indicated that significant carbon losses have taken place due to forest changes to agricultural farms.  Agro-forestry system can lessen these losses from vegetation, litter, soil and due to soil erosion. Agricultural farm with maize and peanut produced lower carbon than forest and vanilla agro-forestry.

Abstract

The aim of the research was to identify the influences of the number of hosts and the density of parasitoid on the behavior of selfsuperparasitism at Trichogramma chilotraeae. The behavior of selfsuperparasitism was studied by examining the percentage of selfsuperparasitism as affected by the variability of host number (3, 6, 12, 24 and 48) exposed to 1 and 2 female parasitoids. A descriptive analysis was conducted in order to identify an ovipositioning sequence. The results indicated that the number of hosts significantly affected the  selfsuperparasitism percentage in the exposing treatments 1 and 2. The percentage of selfsuperparasitism was positively correlated with the ratio of the host number and the female parasitoid density. The tendency of the selfsuperparasitism behavior occurred in the early stage of ovipositioning.
