No full textThe impact of different coastal locations on the growth and Land suitability tissue culture on the Lampung Coast, Indonesia
No full textThis research was conducted at three different locations in the coastal waters of Lampung Indonesia, namely Hurun, Ruguk, and Pahawang, for one- month (March – April) 2021. The cultivation method used is the Long Line method, consisting of 20 points across four lines, with an initial weight of 50 g of seedlings per planting point. A land suitability analysis was conducted by scoring method (23–45), followed by observation of seaweed growth in each location. The result of observation and assessment of land suitability shows that the waters of Ruguk with a score of 38 and the waters of Hurun with a score of 34 are appropriate criteria for seaweed cultivation while the waters of Pahawang are less suitable criteria by the score of 28. receiving a score of only 28. The growth of seaweed, characterized by weight gain, absolute growth, and specific growth rate, was different among locations. The best results were obtained in Ruguk, which achieved a total production of 26,700 g/m and a daily growth rate per month of 8.54%, followed by Hurun, with a total production of 13,680 g/m, and an average daily growth rate per month of 6.32%. Pahawang had the lowest production yield of 9,900 g/m, with an average daily growth rate per month of 5.35%. The assessment of land suitability analysis is very important in land planning and management so that land use can be sustainable and by local environmental characteristics

The impact of resources availability on phytophthora population dynamics and ecosystem health
No full textThe relationship between resource availability and the population dynamics of Phytophthora species plays a critical role in shaping ecosystem health. Phytophthora is a genus of oomycetes that known for their impact on agricultural and natural ecosystems. Resource availability, encompassing both abiotic factors like soil nutrients and moisture, and biotic factors such as host plant density and diversity, influences Phytophthora populations and their pathogenicity. This interaction often results in complex feedback loops where shifts in resource availability can worsen or mitigate the spread of Phytophthora infections. For instance, high soil moisture levels and nutrient availability can enhance pathogen growth and sporulation, leading to increased disease incidence and severity. Conversely, resource limitations may suppress pathogen populations but can also lead to reduced host plant vigor, indirectly affecting ecosystem health. Understanding these dynamics is crucial for effective management strategies, as it helps in predicting disease outbreaks and implementing measures to sustain ecosystem functionality and resilience. This study highlights the need for integrated approaches that consider both the ecological impacts of Phytophthora and the broader implications for ecosystem health, emphasizing the importance of resource management in mitigating pathogen-related disruptions
