Initiating Model of Agricultural Development Based on Local Wisdom: The Case of Risk Mitigation of Organic Rice Farming in Indonesia

Agricultural development in Indonesia still depends on ideas and practices taken from outside or international agency. By the less successful integrated pest management in Indonesia encouraged by FAO, and the imperfection of organic rice farming (ORF) is still one stretch and has the same water flow with the conventional farming, it could be probably contaminated by chemical residue, and therefore, the agricultural development based on local wisdom can be a valuable alternative. Pleasantly, Indonesia is rich with farming local wisdom, and the research about this local practice is frequently conducted. But, unfortunately, this research is merely to describe it case by case in local context and does not yet become a systematic planning for agricultural development. Therefore, the aim of this research is not only to explore farmer local wisdom in mitigating risk of organic rice farming especially in pre-planting period, but to formulate the items of this mitigation into a planning which could gradually be implemented as the first & second priority, the items that have been completely implemented, and as the aspects of mitigation which are not important to develop. By in-depth interview with the prominent farmer, this research finds five items of local wisdom to mitigate the risk of organic rice farming, in which part of them are making a filter tub upstream into organic rice fields, topped with water hyacinth (eceng gondok); providing rice seeds by themselves; and the seed to be planted should come from organic seedbeds. Adopting the Importance Performance Analysis to the 109 samples in Tasikmalaya, West java -- which the sample size is determined by Slovin formula with below 7% of error probability and adopts stratified proportional random sampling -- this research which proves eceng gondok planting in the upstream is one of the local wisdom that is usually practiced to mitigate ORF, and it should be maintained. Another action that should be maintained is the awareness that the seeds should come from organic seedbeds. While, the agreement that farmer group association should provide rice seeds themselves is one of local wisdom that should be prioritized in agricultural extension. Based on this research, the model of agricultural development could be on the basis of local practices, and it could be implemented in Indonesia as well as in other countries that have local wisdom.

The invasive apple snail Pomacea canaliculata in Indonesia: a case study in Lake Rawa Pening, Central Java

The occurrence of the invasive apple snail Pomacea canaliculata in Indonesia was first reported in 1984. The species was introduced as an ornamental aquarium pet. Since then, people have begun to culture the snail in ponds usually adjacent to rice fields. When it was realized that the species multiplied rapidly and was a serious pest, this invasive apple snail had already spread widely. There are many cultural methods of controlling and preventing its distribution, but none are effective in keeping them at non-damaging levels. We mapped the distribution of P. canaliculata in Indonesia from the MZB’s collections as well as literature references and found that the snail invaded almost all large islands, such as Sumatra, Java, Kalimantan, Sulawesi, Maluku, and West Papua. We also studied the impact of P. canaliculata on the native apple snails P. ampullacea, P. scutata, and P. virescens in Lake Rawa Pening (a popular tourism destination) as a case study. The results showed that two species of Pila already disappeared from Lake Rawa Pening. Only P. scutata occurs still in the region and was found alive usually in shallow water and rice fields surrounding the lake. To resolve the problem we recommend that cleaning the lake periodically from the invasive aquatic weed Eichhornia crassipes (known to locals as “eceng gondok”) by a private company and harvesting the weeds for the local small craft industry by the local fishermen could be an alternative measure to reduce the population of the P. canaliculata, as well as collecting P. canaliculata for local food or for feeding ducks. Rearranging the number of fish-pens “karamba” and their location in the lake could be seen as an alternative way also for reducing the population of P. canaliculata, since the snails lay their egg masses on the bamboo stakes of “karamba.” Such rearrangement could make the landscape more attractive for tourism.

A Review of Pyrolisis of Eceng Gondok (Water hyacinth) for Liquid Smoke

The growth of eceng gondok (Water hyacinth) in Rawa Pening Lake showed rapid increase.. Based on the mandate of the National Lake conference in Bali and the 16th World Lake Conference, Rawa Pening is one of the fifteen national lakes which need to be treated for its conservation. Reducing number of eceng gondok plants is one of the alternatif. However, further processing is required to treat the waste of eceng gondok. One attempt is to convert eceng gondok (water hyacinth) into liquid smoke product. This article reviewes the potency of eceng gondok for liquid smoke through pyrolisis method. The liquid smoke can be used for various applications such as preservatives, antioxidants, biopesticides and perisa disinfectants. Pyrolysis is a combustion process in the absence of oxygen to produce liquid and charcoal activated charcoal products called activated charcoal. The pyrolysis process is generally carried out at a temperature range between 200-700 °C. The pyrolysis process is one of the methods chosen in order to strive for development that suppresses the formation of CO gas but releases water vapor. Pyrolysis at a temperature of 300-700 ° C, produces the most dominant compounds 1.6 Anhyro-beta-d-glucopyranose, phenol, and acetic acid. The reaction that occurs during pyrolysis of this temperature is the release of water vapor instead of carbon gas so that it is safe for the environment. The discussion on this article focused on the production of liquid smoke from eceng gondok biomass.
