“…According to Sutono et al (2017), hot clouds heading west and south caused severe disturbances to the MMNP forest in the Cangkringan Resort and Srumbung Resort area with volcanic ash as high as 15 cm. Volcanic ash that comes out during an eruption is a source of accumulation of soil organic carbon (SOC) (Fiantis et al 2019;Hunziker et al 2019) and a source of macro and micronutrients in the soil (Mulyaningsih et al 2012). Residents in 30 buffer villages (Garjita et al 2013) utilize the soil fertility around Mount Merapi for agriculture and building raw materials (Sutono et al 2017).…”

The eruption of the most active volcano in Indonesia, Mount Merapi, has resulted in a very dynamic landscape as a form of ecosystem succession. This study aimed to analyze the carbon stock and vegetation composition in the secondary forest with variations in the level of disturbance after the 2010 eruption of Mount Merapi. Data collection was carried out in January 2020, in which biomass, necromass, and soil organic carbon data were taken in plot transect and Geographic Information Systems carbon stock products compared field data. The results showed that secondary forests at stations A and B with low and medium disturbance levels had carbon stocks in the high category. In contrast, station C at Cangkringan Resort, with high disturbance levels, still had carbon stock with a low category. Furthermore, the comparison of 2020 field data with GIS carbon stock products concluded a similar pattern between carbon stock from aboveground biomass WHRC 2010 and belowground biomass NASA 2010. This research concludes that the disturbance affected forest carbon stocks ten years after the 2010 Merapi eruption. Therefore, monitoring the vegetation community needs to be carried out annually through a combination of spatial and direct checks in the field.

Fish is an environmental bioindicator and a contributor to the daily intake of mineral elements. The content of mineral elements in fish is influenced by what it eats and its environment. Moreover, based on location, around the north coast of Java there are denser residential and industrial areas compared to around the south coast of Java. In this study, we analyzed the mineral content of fish of the same species originating from the southern and northern seas of Java using neutron activation analysis. Fish samples of the same 11 species were each collected from fish auctions in Pemalang and Garut districts. The samples were washed, and then the meat was taken and dried by the freeze-drying method. The samples were irradiated in the G.A. Siwabessy multi-purpose reactor through the rabbit system then counted using gamma spectrometry. The results obtained as many as 17 mineral elements in fish: Na, K, Mg, Cl, Ca, Br, Fe, Zn, Sr, Al, Cr, Se, Rb, Mn, Co, Hg, and Cs. Statistical test results show that there are various differences (positive covariance on 14 elements, negative covariance on 3 elements) for each element between fish from the South Java Sea and North Sea, which indicates that marine environmental conditions have contributed significantly to changes in mineral content on fish.

Potassium (K) is an essential nutrient and one of the main minerals in the blood as a counterweight to electrolyte and blood pressure. Decreasing K intake can be one of the causes of increased blood pressure. Mamuju is one area with high hypertension cases. Potassium is widely obtained from foodstuffs. In this study, food was collected from the markets in Mamuju Indonesia and analyzed using neutron activation analysis to determine K concentration. The results for the meat and egg category show that beef has a higher potassium concentration than chicken meat, and Negeri chicken eggs are higher than Kampung chicken eggs. For the vegetable category, six samples have very high concentrations of potassium, namely caisim, kemangi, fern leaves, chinese cabbage, spinach, and beans; and the spices namely turmeric and kencur have high concentrations of potassium. For the fish and seafood category, tilapia has the highest potassium concentration and the lowest shrimp. For staples, the highest concentration of potassium is found in potatoes, the lowest in sticky rice; and the processed soybeans, tempeh has a higher potassium concentration than tofu. Therefore, it is important to pay attention to daily potassium intake by looking at the combination of food and potassium concentration in it, such as by increasing consumption of vegetable foods. On the other hand, high potassium intake needs to be followed by a reduction in sodium and salt intake in food.
