Abstract

Traditional brackishwater aquaculture in Indonesia focuses on production of shrimp and milkfish. However, since the 1990’s production of shrimp, particularly Penaeus monodon, has become problematic because ofthe prevalence of white-spot disease. Crop losses due to white-spot disease have limited production of P. monodon in traditional tambak throughout Indonesia. Because of this, many tambak have fallen into disuse, or their use islimited. In response, we are developing and trialling diversification options for tambak farmers in Aceh and South Sulawesi. Alternative production options that we are evaluating include Nile tilapia (ikan nila) and soft-shell crab(kepiting lunak) in Aceh, and Nile tilapia, swimming crab (rajungan) and rabbitfish (baronang) in South Sulawesi. In Aceh our main focus has been on Nile tilapia (Oreochromis niloticus) culture, either alone or co-cultured with milkfish (Chanos chanos). We have undertaken trials with farmers in Samalanga and Jangka (Kab. Bireuen) and Banda Mulia (Kab. Aceh Tamiang). Overall, our trials have shown that tilapia will grow and survive well at salinities below 20 ppt. Above 20 ppt, growth rate is reduced and the fish are prone to bacterial disease. At salinities above 20 ppt, milkfish (bandeng) perform better in ponds than tilapia. Our trials in Aceh have demonstrated that Nile tilapia can provideincome to farmers comparable with shrimp culture. Out of a total of 22 trials to date, 9 ponds (41%) have met or exceeded our reference profitability of IDR 1–5 million per hectare per crop. Fourteen ponds (64%) have been‘profitable’, i.e. have generated positive economic returns. This figure is similar to the profitability figure for traditional shrimp ponds (64–73%), indicating that Nile tilapia culture in brackishwater ponds provides economic returns similar to traditional shrimp culture. Based on these results, we recommend Nile tilapia culture to farmers whose ponds are 20 ppt. This provides a profitable production option for farmers in areas subject to low salinities, or during the rainy season when salinities are depressed. Because outbreaks of white-spot disease are particularly common and severe during the rainy season, Nile tilapia culture provides a viable option for income generation for Acehnese tambak farmers under conditions where shrimp culture is too risky

Abstract

Agricultural yield was negatively impacted by salt stress throughout around the world affecting production whether it is for economic gain or subsistence. The tolerance of Acehnese local rice on salinity stress was studied with using osmotic condition in the method of in vitro germination. NaCl was applied on medium MS for the salinity stress simulation for studying the capability of the various osmotic conditions in selection of some Acehnese local rice for the tolerance of salinity stress. The objective of this research was to simulate with in vitro method the tolerance of some varieties of Acehnese local rice on salinity stress during seed germination. Sixteen varieties of Acehnese local rice was sterilized and germinated in vitro for tens days in 250 ml bottle containing 25 ml of medium MS with applying NaCl as concentration 0, 0.5, 1.0, 1.5 and 2.0 g/liter. The varieties of Acehnese local rice that used in this research are Ciherang as control variety, and Acong, Padi Mas, Aweuh, Rom Mokot, Bo Santeut, Sigudang, Bo 100, Sanbei, Sigupai, Manggeng, Sipirok, Padi Berselona, Salah Mayang Ru, Pandrah, dan Sikuneng. The results of this study showed that the tolerance of Acehnese local rice different significantly on observed viability of the seeds: seed growth rate, germination capacity, growth velocity, growth unity, and seedling fresh weight. The osmotic condition of NaCl resulted an effective method to simulate the tolerance of salinity stress for Acehnese local rice using NaCl in the method of in vitro cultivation. The solution with 2.0 g/l of NaCl that used to study the responds of Acehnese local rice to the tolerance of salinity stress was obtained as the best concentration. Thus, simulation of salinity stress condition on Acehnese local rice will become an alternative method for selection of genotype traits related to the tolerance of salinity stress for local rice in the future

Abstract

The potential of fluorescent bacteria as biological control agents for white root disease caused by Rigidoporus lignosus has been investigated. Isolation of bacteria from the soil using S1 media produced two fluorescent bacteria isolates. Using the Microbact 12A+12B method, both bacteria were identified as Pseudomonas fluorescens and P. aeruginosa. These two species of bacteria were then used as antibiosis activity test against R. lignosus. Four series antibiosis activity tests were done, that were antibiosis test of media culture bacteria growth to R. lignosus colony, antibiosis test of dry fluorescent pigment extract to R. lignosus, influence of Fe3+ to antibiosis activity of bacteria test, and affinity of media supernatant to Fe3+. The results were: antibiosis activity of King’s B (KB) media was more effective than media 523 in the inhibition of R. lignosus colony growth. There was no significant different antibiosis activity of dry fluorescent pigment extract from media KB and media 523 in the inhibition of R. lignosus colony growth. The level of Fe3+ in the media might influence antibiosis activity of fluorescent pigment. Affinity test of KB supernatant from fluorescent bacteria culture with Fe3+ showed an absorption peak of 410 nm on spectrophotometer, and none for the fungi. These results indicate that P. fluorescens and P. aeruginosa produce cathecol-type siderophore with high affinity against Fe3+ compared with hydroxamate-type siderophore which is generally produced by fungus.
