High-quality tree seedlings are a key component of landscape restoration. The limited supply of quality seeds has been an obstacle so far. C. inophyllum is a tropical tree species that grow well under harsh environmental conditions. It can be used as an alternative tree species for degraded land rehabilitation. We present an efficient and reproducible protocol for improving seed quality with exogenous NAA hormones. The Murashige and Skoog (MS) medium was supplemented with NAA hormones (0 mg/l, 1 mg/l, 2 mg/l, and 3 mg/l of NAA) for observation of the influence of the exogenous NAA on seeds germination in micro-environment controlled. After seven weeks of incubation in axenic culture, the highest concentration of NAA (3 mg/l) showed the fastest average seed-breaking time of C. inophyllum (2.0 weeks), After three weeks, the roots were nearly five times longer (4.9 ± 0.1 cm) than the control (1.1± 0.1 cm), and the shoots were nearly three times longer (4.9 ± 0.1 cm) than the control (1.1± 0.1 cm).

If not properly managed, coastal abrasion can lead to other environmental issues, such as damage to mangroves and coastal ecosystems. The local government is actively carrying out mangrove ecosystem restoration program to conserve the coastal ecology by involving related agencies, industries, and the community surrounding the Juntinyuat coastal area. The focus of this research is to find out the planning, implementation, and monitoring carried out in relation to the restoration of the mangrove ecosystem based on the involvement of the parties in overcoming coastal abrasion on the coast of Juntinyuat, Indramayu Regency, West Java. Data were collected by conducting observations, interviews, and documentation to the community and the parties involved in restoring the mangrove ecosystem on the Juntinyuat coast. The results showed that mangrove ecosystem damage in the coastal area of Juntinyuat generates a high level of abrasion. The damage caused by abrasion threatens settlements, ponds, and agricultural land, as well as threatens the gas and oil pipelines of Pertamina Gas in the West Java operation area (Pertagas OWJA). There is a relationship between the critical condition of the mangrove ecosystem in the Juntinyuat coastal area and the initiation of efforts to restore the mangrove ecosystem. The initiation of mangrove ecosystem restoration arose from the critical condition of mangroves, which necessitates careful planning to restore damaged mangrove conditions. Related parties concerned with the preservation of the mangrove ecosystem subsequently coordinate to plan the mangrove ecosystem restoration program on the Juntinyuat coast. The mangrove ecosystem restoration was conducted after an initial survey in mid-2014. The role of the parties in planning, implementing, and monitoring the restoration of the mangrove ecosystem is running well and maximally with a clear division of duties and responsibilities. Currently, the results of the restoration of the mangrove ecosystem on the Juntinyuat coast can be felt together with the denser mangrove cover, reducing the abrasion impact, and making it a mangrove ecotourism area. In the future, it is necessary to form a coordinating team for the strategy of mangrove ecosystem management at the regency and sub-district levels to synergize policies and programs for managing mangrove ecosystems. Empowerment activities need to be carried out intensively to encourage a change in the role of mangrove management.

These challenges need extensive interdisciplinary approaches enabling multiple perspectives from diverse stakeholders to be recognised and utilised.

We are therefore happy to see the growing number of community-based participatory studies being submitted to InJAST and hope these will increase in future. There are exciting and vitally important issues to be tackled and supported by environmental managers to build the necessary environmental security and resilience, from direct conservation work to flood risk management and pollution control. Climate change drives or affects all these of course and has been, for example, one of the key drivers for Indonesia’s momentous plans to move the capital from the 256,000-hectare (990-square-mile) Jakarta on the north-western side of Java Island, the most populated island in the country, to the relatively undeveloped and biodiversity-rich East Kalimantan province on the island of Borneo. Climate change and immediate economic drivers in many parts of Indonesia also contribute to the annual toxic haze, which causes air quality to reach hazardous levels and creates major health, environmental and economic problems, especially in Sumatra and Java.

She has asked me to share with readers some further, personal thoughts on this topic. I am an ecologist by training, but I spent much of my career managing agricultural research programmes in tropical regions. For the last ten years, I have held a position in a school of public health. This varied disciplinary experience has given me the opportunity to explore and understand interactions between environment, agriculture and human health. It is helpful to think of environment, agriculture, and health as points in a triangle, each having specific interactions with an adjacent sector, but also being influenced by more complex, three-way interactions. For environmental scientists, the interactions with agriculture are probably the most familiar. Extensive planting of crops like rice and oil palm has dramatic effects on biological diversity, water systems and their function, and soils. The importance of healthy environments to agriculture is repeatedly demonstrated. Thirty years ago, I had the opportunity to review the Indonesian national programme on integrated pest management in rice. Use of pesticides on rice was, paradoxically, causing severe outbreaks of pests like brown planthopper. The environmental processes behind this were actually quite complex. Soon after flooding, aquatic arthropods colonizing rice paddies provided a food source for generalist predators that moved in and built levels capable of suppressing subsequent pest invasion. Pesticides killed off this general predator community, while the pests, which lay their eggs inside plants, were less affected and their populations exploded in this predator-free environment (Settle et al. 1996). Integrated Pest Management (IPM) on rice, pioneered in countries like Indonesia, was for many years a leading example of the value of integrating environmental and agricultural research.Environmental scientists will be less familiar, perhaps, with the interactions between agriculture and health, so here is a short introduction. Agricultural systems have two impacts on health, which for historical reasons have been treated as separate disciplines in the health sector. They produce food that contributes to nutrition, which is usually, but not always, a health benefit, and they produce distinct health risks, including diseases associated with food and food production, and toxins associated with agriculture, such as the pesticide just mentioned.","PeriodicalId":191982,"journal":{"name":"Indonesian Journal of Applied Environmental Studies","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116631556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
