Abstract

Pseudomonas solanacearum is a bacterial agent causing wilt disease on mulberry species and other woody plant in Indonesian. Biological control employing the antagonist bacteria such as P. fluorescens and P. Putida is a potential method. The aim of the research was to know the effectiveness of P. fluorescens and P. putida to suppress wilt diseases caused by P. solanacearum. The diseases control test with antagonist bacteria was conducted by immersion of root of seedlings in P. fluorescens and P. putida suspensions before planted in a growth medium inoculated by P. solanacearum with the all concentrations were 108 CFU/ml. The following parameters were observed: numbers of leaves, fresh and dry weights of leaves and severity of disease. The results of the effectiveness test showed that antagonist bacteria in the form of mixing of P. fluorescens and P. putida was the best, because they were capable to suppress wilt disease caused by P. solanacearum and increased productivity of mulberry leaves. keywords : antagonist bacteria, biological control, wilt disease

Abstract

Grasserie disease is one of the serious diseases caused by viruses. Its symptoms generally appear in the last instar of silkworm larvae or just before the formation of the cocoon. This study aimed to determine the level of attack, yield losses and dispersal patterns of grasserie at three sericulture center in South Sulawesi, Districs (Wajo, Soppeng and Enrekang). At each location 10 farmers were selected purposively as respondents. Direct observation was conducted to the farmer’s rearing rack (on farmer’s rearing bed) of silkworm using five replications. The results showed that the attack rates of grasserie were categorrised as very slight, ranging from 3.06 to 3.72 kgs of yield losses per each box with a uniform pattern of disease spread. Reared of  silkworms in accordance with standard operating procedures can reduce the rate of grasserie disease to avoid losing larger cocoon yields.

Abstract

The forest bee farmer group in Rompegading Village still has problems regarding the limitions of hunting for forest bees which are only seasonal, safety and environmental risks and limited knowledge of trigona bee cultivation. With the program offered, the community can start a new business, namely trigona bee cultivation independently. The implementation of this program stars from socializing the introduction and potential of trigona bees, opening/cleaning cultivation/meliponiary areas, making bee houses, making paths to bee houses, planting food/flowers around bee houses, making bee boxes, searching for colonies in nature, installation of meliponiary signage, site fencing and monitoring and evaluation of activities. The activity was carried out for approximately 5 months starting from July to November 2021. The first harvest of 500 ml of trigona honey was sold and became a special satisfaction for member of the partner group. The Trigona Bee Thematic Village Development Program as an Effort for Community Empowerment in Rompegading Village, Maros Regency can be considered to have gone well because all activities carried out are carried out according to the scheduled timeline. It is hoped that from this PHP2D, the community of partner forest farmer groups have skills in trigona bee cultivation by utilizing the potential of the surrounding environment, so this can be the first step for them to start a trigona bee cultivation business so that it is hoped that a thematic village that is independent and caring for the environment will be created.

Abstract

Indonesian silk farming (Sericulture) has experienced two waves of a pebrine epidemic (also known as pepper disease) and grasserie. The first pebrine epidemic occurred in 1973 and the second one occurred in 2010. Natural silk production in Indonesia has undergone dramatic decline after these epidemics. In addition to the disease, other factors also simultaneously contributed to the decline. This research examines the conditions and challenges to national natural silk industry recovery after a pebrine epidemic. The present study employs a survey and focus group discussion in three regencies (Wajo, Soppeng, and Enrekang), which took place in September 2016. Findings show that there are three major factors which contribute to the decline of national silk production, namely the: i) epidemic of silkworm disease, ii) quality of silkworms and the process of silkworm provision, iii) insufficiency of farmer means of production, and iv) lack of guidance and assistance for the farmers. Without interventions and greater support to properly maintain silkworm operations a potentially lucrative economy for rural farmers could go unrealized. The implications of this research also highlight key potential interventions for working with communities and supporting the overall resilience of national silk production in Indonesia.
