Abstract

In Indonesia, low soil P availability is the major constraint in upland area.  Therefore, it is needed to find soybean varieties with characters efficient in P and high yield.  The objective of this study was to evaluate P uptake, P efficiency, yield, morphological and physiological characters for selection of P efficient varieties.  A Randomized Completely Block design was used with three replications.  Seven varieties i.e. local, Slamet, Leuser, L1 503, S1 131(2), SL3 113(6), S1 053 and P applications i.e. without P and 36 kg P2O5 ha-1 were tested.  Some variables such as plant height, shoot weight, leaf number, branch number, filled and unfilled of pod number, grain weight, P content, P uptake and efficiency were analyzed.  Data was analysis by F test and followed by DMRT.  The results showed that there were different responses on P uptake among genotypes under low P condition. Slamet, S1 053, SL3 113 (6) and Leuser had characters of high potential of yield and efficient in P uptake under P stress.  Some characters could be used for variety selection of P efficient with high yield i.e. shoot and grain weight, and P efficiency.

Abstract

Pot experimental research under green house condition was carried out in Yogyakarta during March-Mei 2009. The aim of the experiment was to determine the influence of soil moisture on growth and yield of local-varieties shallots (Palasa, Palu and Sumenep) at different elevations. The experiment was arranged in a Split Split Plot Design with three replications. The main plot was local varieties of shallot: (1) Palasa; (2) Palu; and (3) Sumenep. The sub-plot were soil moisture (field capacity percentage - % FC), included: (1) 50% FC; (2) 100% FC; and (3) 150% FC. Each variety has a different response to different soil moisture and altitude places.  Sumenep variety had the lowest net assimilation rate (NAR) and Palasa variety produced smallest fresh-bulb at all soil moisture and elevation. Soil moisture at 100% FC increased crop growth rate (CGR) and bulb’s fresh-weight per crop bunch of Palu variety particularly on elevation 100 m above sea level, whereas 50% FC reduced shallot growth and yield on all elevation.

Abstract

The purpose of this study was to determine the characteristics of edible films made from highamylase arenga starch, and its application as noodle seasoning powder packing. The treatment wasfractionated natural arenga starch at 70 and 80oC. Edible film was constructed from arenga starchsolution at a concentration of 2.8% (w/v) added with glycerol plus solution 0.5% (w / v) and thenheated at 85oC for 5 minutes. The next process was the addition of palm oil (palmitic acid) with aconcentration of 10% (w / w polymer) in the same condition. The solution then was poured in aplastic plate and oven dried at 50oC for 18-24 hours. Once dried, it was cooled at room temperaturefor 15 minutes. Parameters observed at this stage were thickness, water vapor transmission rate,tensile strength and elongation. The results showed that characteristics of edible films producedfrom the arenga starch at 70oC included thickness 0.103 mm, water vapor transmission rate(WVTR) 5.09 g/m2h, tensile strength 32.76 MPa and elongation 2.60%; while for the fractionatedarenga starch at 80oC included thickness 0.104 mm, the WVTR 2.55 g/ m2h, tensile strength 44.03MPa and elongation 1.71%. It is suggested that edible films produced from fractionation can beapplied as packing noodle seasoning powder that dissolves less than 3 minutes.

Abstract

In the current era, government has facilitated, trained and supported the implementation ofirrigation development and management providing maximum opportunities to any region, bybringing forward the initiative, capacity, and the regional authority concerned in accordance withthe economic and decentralization spirits. However, based on the present data, it is suggested thatirrigation improvement program has not been able to absolutely alleviate poverty because irrigationis only one of supporting capitals in farming system. The research was conducted in ParigiMoutong from March 2009 to December 2010. Data was collected through survey aimed at: (1)analyzing poverty incidence and gap; (2) identifying government policy on irrigation developmentand management. The research results showed that: (1) based on the poverty incidences and gapanalysis, Torue and South Parigi sub districts had populations of poor people of 55.89 and 49.36%,respectively, (2) the Central Sulawesi governmental policy on Water Resources and IrrigationSector Management Program (WISMP) has been running for 3 years, which is currently a priorityprogram in managing water/irrigation resources. Its implementation is needed in order tosuccesfully create self-supported farmers in participative irrigation management by activelyinvolving water user farmer groups (WUFG) directed to foster the sense of belonging. Thus,responsibility transfer in management can run smoothly and the realization of efficient, effectiveand sustainable irrigation based on self-supported farmer community belong to WUFG isachievable. The WISMP can reduce the poverty level 5% but it was not significant in alleviating povertyKata kunci : Irrigation, poverty, regional government policy.

Abstract

This study aimed to determine the influence of embryonic axis length and the storageduration on palm seed germination. The study was conducted at the laboratory of SeedScience and Technology, and the green house of Agriculture faculty-UNTAD from April toNovember 2008. A randomized block design with two factors was used. The first factorwas the axis length of embryo consisted of three levels (<2 cm, P1); 2-4 cm, P2; and >4 cm,P3). The second factor was the storage duration (10 days, L1; 20 days, L2; and 30 days, L3).All treatment combinations were replicated 3 times. The variables observed were: axislength of the embryo, seedling height, number of leaves, stems diameter, root length, dryweight of root, dry weight of shoot, and hypothetic index of vigor. The results showed thatthe axis length 2-4 cm of embryos stored for 20 days (L2P2) resulting in the best responseon germination of palm seeds compared to other treatmentsKey words: Stored duration, sugar palm, the axis lenght of the embryo.

Abstract

Cocoa bean is important (top) commodity especially in plantation sub-sector, and generallyin agriculture sector in Central Sulawesi Economy. The aim of the study was to identifyand to analyze the productivity function of smallholders’ cocoa farm in Central Sulawesi.The panel data analysis, i.e. fixed effect model was applied. Data used were secondarytime series data of 2000 – 2008, i.e. regency production and prices of cocoa beans, pricesof substitution commodity, prices of input factors, regency inflation, GDP and theexchange value of the currency's main export destination countries (Malaysia and USA).The secondary data was confirmed with primary data taken by purposive and unproportionalstratified random sampling techniques. The number of farmers interviewedwas 138 people. The results of the research showed that the productivity of smallholders’cocoa farm tended to be constant even decreased. Instead of having negative effect onproductivity, GDP of USA, and pesticide prices were found to have significant and positiveeffect. Besides, wage had negative effect but statistically significant. This is reasonablebecause cocoa farming requires a high level of maintenance. Finally, GDP of Malaysia hadnegative effect but statistically significant suggesting that the quality of the cocoa beanscoming from the province was low.Key Words : Cocoa farm, productivity function, and smallholders.

Abstract

Four antagonist bacterial strains, Pseudomonad fluorescent strain UTD1 (Pf-UTD1), Pseudomonad fluorescent strain UTD2 (Pf-UTD2), Bacillusspp. strain UTD1 (Ba-UTD2), and Bacillusspp. strain UTD1 (Ba-UTD1) which had been found  to have biocontrol activity  in vitro assays against blood disease bacteria, the causal agent of wilt banana, were tested for their compatibility in vitro and its antagonism  in  screen  house using  banana  budless  Kepok  as  test  plant.  The compatibility  test showed  that  Pseudomonad  fluorescent strain  UTD1  was  only  compatible  with Pseudomonad fluorescent strain UTD2, Pseudomonad fluorescent strain UTD2 compatible with all antagonist (Pf-UTD1, Ba-UTD1, dan Ba-UTD2), Bacillus  spp.  strain UTD1 only compatible with Bacillus  spp. strain UTD2,  and Bacillus spp.  strain UTD2  compatible with all  antagonist  (Pf-UTD1, Pf-UTD2 and  Ba-UTD1).  Inoculation  with  blood  disease bacteria  caused  significant  wilting,  and  reduced plant growth.  Single  Inoculation  using  either  Pseudomonad fluorescent  UTD1  or  Bacillus  spp. UTD2  causing  greater results with  no wilting. Combination  between Pseudomonad fluorescent UTD2 and Bacillus spp. UTD2 also  showed no wilting. Generally, all treatments were considered good because  they  could  reduce  disease  intensity  less  than 25%,  except  for  Pseudomonad fluorescent UTD2  and Bacillus  spp. UTD  treatments which  caused wilting  up  to 38.89%.    The results suggested  that both single and combination  treatments of Pseudomonad  fluorescent UTD2 and Bacillus spp. UTD2 can be used to control blood disease bacteria in wider scale.  Key words: Bacillus spp., biological control, blood disease bacteria, pseudomonad fluorescent.

Abstract

Cassava (Manihot Esculenta Crantz) is one of the export commodities from food crops sub-sectorand has potency to be developed. Indonesia is the biggest fourth producer of cassava in the worldafter Nigeria, Brazil and Thailand. Cassava grows very well under limited rainfall and poor soilconditions, with flexibility in planting and harvesting period. However, the negative impact andimage of cassava cause existing potency cannot be improved optimally, either in export or domesticmarket. This research aimed to identify level of comparative advantage and competitive position forthe Indonesian cassava products. Revealed Comparative Advantage (RCA), SpecializationCommerce Index (SCI), and Acceleration Ratio (AR) analysis were implemented to determine thecompetitiveness rate of Indonesian cassava. The result of analysis will be used as the basicdeterminant of Indonesian cassava export and domestic market potencies. The results of theresearch showed that Indonesia has a strong comparative advantage for the commodities of cassavaand tends to be net exporter.Key words : Cassava, competitiveness, export market, domestic market.
