INDONESIAN FARMERS CAN CONTRIBUTE IN REDUCING GREENHOUSE GASES EMISSION FROM WETLAND RICE FIELD

Agricultural sector contribute significantly to the total GHG emission. There are some GHG mitigation options available but so far non of these mitigation options is being implemented by farmers. There is no real action have been taken by government to encourage farmers to implement the available mitigation option to reduce GHG emission from wetland rice field. We discuss some mitigation options and we suggest two additional GHG mitigation options namely crops rotation and System of Rice Intensification (SRI) that probably more attractive to farmer to implement them. However the impacts of these two proposed options as GHG mitigation options should be studied further.Key words: Greenhouse gases (GHG), mitigation option, farmer contribution, SRI, crop rotatio

Faktor-faktor yang Berhubungan dengan Perilaku Kesehatan Reproduksi Remaja Putri di Program Studi D-iii Kebidanan STIKES Hang Tuah Pekanbaru

Indonesia's population has reached around 262 million. The high population must be balanced with efforts to improve the quality of the population. One effort to improve the quality of human life can be done through efforts to improve reproductive health, especially for young people and the younger generation, this will increase the index of human resources in the future. This is because the number of adolescents in Indonesia today is quite large, one third of the composition of Indonesia's population is adolescents, so adolescent reproductive health remains one of the priority health programs in Indonesia because there are still many teenagers who pay less attention to reproductive health in Indonesia. at risk of reproductive health. This study aims to determine the relationship between knowledge and attitudes toward reproductive health behavior in the Midwifery Study Program STIKes Hang Tuah Pekanbaru. This type of research is Analytical Quantitative with Cross Sectional design method. The population in this study were all students of the Midwifery D-III Study Program at STIKes Hang Tuah Pekanbaru who attended 170 research participants with the Total Sampling technique and using Univariate and Bivariate Data Analysis. The results showed that there was a significant relationship between knowledge and behavior of reproductive health (pValue = 0.00 <0.05 POR = 4.850), and there was a significant relationship between attitudes and behaviors of reproductive health (pValue = 0.0042 <0.05 values POR = 7,700). It is expected that teachers or lecturers can cooperate with parents to provide good knowledge and guidance on reproductive health from an early age and can provide a good source of information about reproductive health. For teens to better equip themselves with knowledge about reproductive health, fill time with things that are useful and increase self-awareness to behave according to social and religious norms. Further research needs to be done on reproductive health with more developed variables and with broader respondents so that solutions can be found to solve reproductive health behavior problems.   &nbsp

The Incidence and Severity of Downy Mildew Disease on Local Madurese Maize Crops in Sumenep District, East Java, Indonesia

In Madura island, corn is the main commodity that is widely planted with an area of 301,725 ha or about 30% of the area of maize in East Java. Madura Island has local cultivars, such as: Tambin, Talango, Guluk-guluk, Manding, and Kretek. Efforts to increase production are continuously being made, starting from improving varieties until managing plant pests. One of the main diseases in maize is downy mildew. However, information about the incidence, incidence, severity, and species that cause downy mildew in local cultivars has not been reported. So, this study aims to identify the causes of downy mildew in local cultivars of Madura and disease severity in the field. The research method is a survey on local maize centers. Sampling was done by using the diagonal sampling method. Each plant sample was observed for symptoms of disease and scoring to calculate the value of disease severity. Fungi identification was carried out by microscopic observation of the fungus. The results showed that the cause of downy mildew in Madura local maize in Sumenep Regency was P. maydis. The highest incidence, disease severity, and AUDPC value after 4 MST were found in Guluk-guluk cultivars in Padangdangan Village, but had the lowest disease progression rate values. Meanwhile, the highest rate of disease progression was found in the Manding cultivar in Mandala Village. Based on the resistance category, Talango cultivar had the best resistance when compared to other cultiva
