Abstract

The aims of this experiment were to determine the most suitable phase of palm sugar tree for producing starch and the characteristics of starch (functional, physical and chemical compositions) which were appropriate for starch noodle. Three growth phases of palm sugar tree were observed, namely: before flowering, productive growth and post growth productive phases.  Starch characteristics analyzed included water content, reduced sugar, starch, amylase, lipid, protein, fiber, ash, acid degree, form and size of granular, and starch amilography. Starch of green bean was used as a comparison.  Results of this experiment indicated that the highest starch content on the palm sugar tree was found at the productive growth phase. The characteristics of starch on the palm sugar at the post growth productive phase were similar to the starch of green bean. Therefore, starch obtained from post growth productive phase is the best for starch noodle.

Abstract

Apple development by vegetative propagation via tissue culture is an effort to reduce the import of apple.  This experiment aimed to investigate media composition (cytokinin and NAA combination) suitable for initiation of apple.  A Completely Randomized Design was employed, with four treatments i.e., : 3 ppm Benzylaminopurine (BAP) + 0.2 ppm NAA (P1), 4 ppm BAP + 0.2 ppm NAA (P2), 2 ppm kinetin + 0.2 ppm NAA (P3) and 3 ppm kinetin + 0.2 ppm NAA (P4), Parameters observed included number of shoots, leaves and nodes. Results of this experiment showed that the use of medium composition with 4 ppm BAP + 0.2 ppm NAA produced the most intensive shoot, leaf and node growth. However, medium composition with 3 ppm BAP + 0.2 ppm NAA had a good initiation quality.

Abstract

The research aims were to determine the cocoa seed vigor of various storage periods and seed invigorant viewed from aspect of seed physiology quality. This research was a two factorial experiment in a completely randomized design. The first factor was the time length of storage consisted of 5 levels: i) Control, ii) 2 week, iii) 4 weeks, iv) 6 weeks, and v) 8 weeks. The second factor was seed invigoration using ZPT consisted of 4 types: i) without ZPT, ii). 0.01 mmol GA3, iii) 0.01 mmol GA3 + 0.1 mmol NAA, and iv) coconut milk. The data obtained was analyzed using variant analysis; the data with coefficient of variation more than 20 % was transformed to x + 0.5 whereas treatment with significant influence was advanced with HSD test with level of 0.05. The research findings showed that a longer period of seed storage led to the reduction of seed vigor. Invigoration with GA3 + NAA also contributed to a better seed vigor though it was not significantly different from GA3 invigoration and coconut milk. All seed invigoration treatment (GA3 + NAA and coconut milk) could slow seed deterioration up to 6 week storage.

Abstract

The research objective was to study the influence of the area of land use pattern and physical environment condition on land and water resource degradation through river water debit identification including its intensity and fluctuation, and sedimentation. The research object covered 12 water catchment areas which area spread at Upper Cimanuk watershed, West Java. Analysis model applied in this research was a multiple regression for determining a correlation between independent variable (X) and dependent variable (Y) on water catchment area unit as in Draper and Smith (1992). Research results indicated that mixed farming system, rice field area and stream form coefficient increased sedimentation. Increasing settlement area and average rainfall per year augmented annual water debit average. Upland farming increased debit fluctuation, annual debit average and sedimentation.  The larger the stream form coefficient and community forest the smaller the annual debit average.  Whereas the larger the water catchment area the smaller the stream debit fluctuation.

Abstract

The objective of the research was to identify the rate and amount of soil water infiltration under various soil characteristics in the Sungai Allu Bankala Watershed.  Data of the measurement can assist to indicate water requirement for different soil types to achieve certain soil humidity. This water requirement can be given by irrigation or precipitation. The research was done in non irrigated paddy or corn land at the Sungai Allu Bankala Watershed, sub district Bangkala District - Jeneponto , South Sulawesi. The types of  soils tested and replication done as follow : Grey Alluvial (2  replications) ; Litosol (3  replications) ; Red Brown Latosol (3 replications ); and Association of litosol and Red Mediteran (2 replications). So that there are 10 location observed. The measurement of infiltration was done using a double ring infiltrometer with measurement interval of 5-6 hours. The results showed that the constant infiltration was achieved after 4-5 hours. The determination coefficient value at linier and non-liniar curve were > 0.9 indicating that the value was sufficiently accurate. The average of infiltration from the highest to the lowest values were as follows Grey Alluvial>Litosol > Association of Latosol and Litosol > Mediteran – Litosol. The first two soil types had very rapid infiltration rate category, while the last two soil types was moderate. The time to achieve a constant infiltration rate under the non irrigated paddy land planted with paddy/corn was faster than other soil condition.

Abstract

The objectives of the research were to examine whether there were differences in the technical efficiency of input allocation of rice farming between wt (with-enso) and wo (without-enso) areas at various planting season and to study whether the input allocation was technically efficient. Data analysis used a production function analysis method and dummy variables. The research results showed that: the dummy variables were significant in planting season II but not significant in planting season I.   The technical efficiency of input allocation in wt and wo areas was significant at planting season I and II, whereas at planting season–t the efficiency was not significant.  The efficiency of urea, SP36 and KCl fertilizer allocation in wt and wo areas was significant at all planting seasons while that of ponska fertilizer only at planting season I and II the efficiency was significant. On the contrary, the efficiency of pesticide in both areas was only significant at planting season-t.

Abstract

The WHO and FAO regulation on the maximum level of 30 ppb aflatoxin in foods and feeds has prompted consumer-countries from Europe and USA to put pressure on producer-countries of cacao seeds to fulfill this requirement.  It is reported that aflatoxin contamination produced by fungi Aspergillus flavus in cacao seeds can occur in crops, in the field, at harvest, during postharvest operations and in storage.  This study aims at identifying mycotoxigenic fungi and their population, the content of aflatoxin in cacao seed at farmer, collecting-traders and exporter levels, and correlation between fungi population with aflatoxin content on cacao seed from Central Sulawesi. At a preliminary study, survey was conducted to determine samples of farmers, collecting-traders and exporters, and samples of cacao seeds (purposive sampling) in Donggala, Parigi Moutong, Poso, Morowali, Buol and Toli-toli districts as well as in Palu city.  Six samples of cacao seed were taken from every district and city (1 kg per seed sample).  Fungi from cacao seeds were isolated using a planting method with Potato Dextrosa Agar (PDA) as a media. The examination for other A. flavus and mycotoxigenic population was determined microbiologically, whereas aflatoxin was determined using HPTLC (High Performance Thin Layer Chromatography).  The results of the study showed that the number of fungi species (9 species), the density of fungi population (1.4 x 109) and the aflatoxin content (104.798 ppb) in dried cacao seed trading at the farmer level were higher than that of at the collecting-trader level          (6 species; 6.5 x 107 population density; 61.305 ppb aflatoxin content) and at the exporter level                 (5 species; 6.0 x 105 population density; 47.737 ppb aflatoxin content).  The fungi found at the ecology of cacao seed were Aspergillus flavus, A. fumigatus, A. niger, Peniciliium sp, Fusarium sp, Mucor sp, Rhizopus sp, Geotrichum sp, Verticillium sp, Trichoderma viride dan Trichoderma sp.
