Abstract

Stunting is a national health problem that is still of great concern to the government. One effort to prevent stunting is to search for local food ingredients that contain nutritional value as an indicator of their ability to become anti-stunting candidates. Sea bean sprouts or also called Lingua unguis are a type of shellfish found on Mutiara Beach, Sukadana City, North Kayong, empirically used by coastal communities as a family food menu. This study aims to determine the content of the essential metals iron (Fe), zinc (Zn) and iodine (I) as elements of nutritious food used to prevent stunting. The research results showed that the Fe, Zn and I contents were 92.09 ppm, 26.44 ppm and 15.2 ppm respectively. Determination of essential mineral content using the Inductively Coupled Plasma (ICP) Mass Spectorophotometer (ICP-MS) instrument.

Abstract

Ecoenzymes are fermented products of organic waste such as fruit and green vegetables, which are rich in nutrients so they have great potential as organic fertilizer. Making ecoenzymes can reduce waste discharge into the environment, thereby reducing pollution, thus supporting environmentally friendly sustainable agricultural practices. This research aims to produce and characterize the macro nutrient content of Nitrogen (N), phosphorus (P), Potassium (K) and organic C from ecoenzymes produced from pineapple and green vegetable waste. Organic waste from pineapple skins and green vegetables is fermented with palm sugar and water in a ratio of 3: 1: 10 (organic material: sugar: water), in a container with a lid for 3 months. The process of observing changes in pH per week was carried out during the fermentation process. Determination of the macro nutrient content of organic N, P, K and C from ecoenzymes produced from pineapple and green vegetable waste using the atomic absorption spectrophotometry method. The research results showed that the organic N, P, K and C contents were 9.5%, 3.01%, 1.02% and 21.04%, respectively.

Abstract

The global climate changes that are currently occurring can have a significant impact on the plantation and forestry sectors in Sesaot Village, West Lombok Regency. Even though the plantation technology used by the people of Sesaot Village is still traditional, there are also very diverse types of plantation crops in the village which can make a significant contribution to the local economy, the main challenge faced is increasing temperatures which have the potential to reduce harvest yields and forest productivity. Due to changes in temperature experienced by the community from year to year, it shows a significant increasing trend. Based on data from the West Lombok Regency Meteorology, Climatology and Geophysics Agency (BMKG), the period from 1997 to 2024 in May shows a trend of increasing temperatures that continues from year to year. This research aims to analyze the concrete impact of global climate change and adaptation on the plantation and forestry sectors in Sesaot Village. In facing this challenge, cooperation between government, society and other related parties is very important. Efforts to increase awareness of the impacts of climate change and encourage the adoption of modern technology in the plantation sector can be key steps in mitigating possible negative impacts.

Abstract

The diversity of marine biota is very high, with nutritional and chemical content that can be used to fulfill food requirements and maintain health. Stunting is a national health problem that has a big impact on the nation's future, so it is necessary to look for local food sources that have the potential to be used in dealing with stunting. The aim of this research is to obtain nutritious food from the sea, which has the potential to be a source of protein and fat and is very necessary for children during their growth and development period, pregnant and breastfeeding mothers. One of these food sources is Lingula unguis which has empirically been used as a side dish by the coastal communities of Mutiara Beach. The results of measuring the macronutrient content of marine biota Lingula unguis show a water content of 75.3%, ash content of 1.12%, protein content of 3.3%, fat content of 2.07% and carbohydrate content using difference calculations obtained at 18.35%. The protein and fat macronutrient content of L. unguis can be a consideration for use in the consumption menu for treating stunting.

Abstract

This study aims to examine the effect of lead (Pb) heavy metal absorption in depuration media on the agar quality and yield of seaweed (Gracilaria sp) from local coastal waters, and to assess its potential use in industry. The research method involved analyzing six seaweed samples using atomic absorption spectrophotometry (AAS) to measure Pb content and calculate the dry matter yield. The results showed that the SB samples (SB1, SB2, SB3) did not contain detectable levels of Pb, indicating that their growing environment was relatively free from heavy metal contamination. In contrast, the SS samples (SS1, SS2, SS3) showed detectable levels of Pb, with the highest concentration in SS2 (2.65 mg/kg). The dry matter yield in the SB samples averaged around 20%, while the SS samples had a slightly higher average yield of around 21.5%. These results indicate that the SS samples had a higher dry matter content compared to the SB samples. Based on these findings, it is concluded that the SB samples are safer for industrial use due to the absence of Pb contamination, whereas the SS samples require further treatment to reduce the risk of Pb contamination. This study emphasizes the importance of regular monitoring and testing for heavy metal content in seaweed to ensure product quality and safety, as well as effective environmental management of coastal waters to prevent heavy metal contamination of vital natural resources.

Abstract

Trash fish has high nutritional content such as protein, fat and essential minerals, so it has the potential to be used as a processed product for snacks. This research aims to make meatballs from trash fish which are added with Eucheuma cottonii seaweed pulp as a binding agent, to partially substitute the use of wheat flour. This research was carried out by comparing the macronutrient and essential mineral Zn content between trash fish meatballs with the addition of E. cottonii and trash fish using wheat flour alone. The characteristics evaluated include texture and taste, water content, ash content, protein content, fat content and carbohydrate content as well as the essential mineral sen (Zn). The results showed that the addition of Eucheuma cottonii flour significantly improved the texture and taste of trash fish meatballs with an average protein content of 17.55%, average fat of 5.57%, carbohydrates of 14.07% and zinc of 5.6 ppm. Trash fish meatballs without the addition of E. cottonii showed a protein content of 15.15, fat of 5.2%, carbohydrates of 22.09% and zinc of 4.2 ppm.

Abstract

The distribution, graduation and conservation of Megapodius reinwardt based on the ecological knowledge of local residents to support ecotourism on moyo island, has been carried out. The objectives are: 1) to obtain an accurate picture of the distribution of the population and its behavior, 2) knowledge of the ecology of the local population, 3) perception and behavior of the local population, 4) to increase the population, and 5) to carry out conservation to prevent its extinction in the Moyo Island. This research consists of two stages of activities, namely first, mapping population distribution, nest analysis, diseases, pathogens, interviews and discussions with local community about their perception and knowledge about M. reinwardt, document study about tourist visits; second, building awareness and participation of local community to support M. reinwardt conservation activities, formulating its conservation design and identifying potential nests as tourist attractions. The perception of the local residents of Moyo Island towards the existence of M. reinwardt is useful in supporting the fulfillment of their life needs directly or indirectly. Locals believe that by keeping M. reinwardt, his life needs can be met. In addition, the locals of Moyo Island think that laboring the bird at the time of laying eggs will be "Mali" or bring bad luck to hunters. The attitude of the local residents of Moyo Island towards the preservation of M. reinwardt is mostly 85% of residents agree with the preservation of M. reinwardt on Moyo Island, 10% are still hesitant and 5% disagree. The efforts to manage M. reinwardt as one of the tourist attractions, must involve and be able to accommodate the needs of local residents, tourists, tourism entrepreneurs and the government. For the success of the bird conservation efforts, six things must be considered, namely: 1) an agreement on the recognition of the minimum rights of group members; 2) the clarity of the boundaries of the scope of control of each active management community group; 3) the suitability between the cost of nest management and the benefits obtained; 4) conflict resolution mechanisms; 5) firmness in the application of sanctions and 6) willingness to receive knowledge/information and technology on the conservation and management of M. reinwardt from outside the moyo island area.

Abstract

Giant prawns (Macrobrachium sp) are one of the freshwater aquaculture commodities that have high economic value (Murtidjo, 1992). The demand for giant prawns in Indonesia has only been met by 40% of all existing demand (Tambunan, 2009. The aim of the research was to analyze the abundance of giant prawns and the size distribution of giant prawns in Togafo Village, West Ternate District, Ternate City. The purposive sampling method was used in this research. Then the sampling points that had been determined using purposive sampling were marked with coordinates with the help of the Global Positioning System (GPS). For the research location, it was divided into 3 observation stations. First, the shrimp body length and weight were measured using calipers and analytical scales. Abundance relative = individual/trip and Distribution of length measurements and distribution of shrimp weight measurements can be grouped using the equation (Effendie, 1979) as follows: K = 1 + 3.3 log n. Note: K = Number of Interval Classes, n = Number of Observation Data, log = Logarithm. Based on the results, the highest abundance of giant prawns (Macrobrachium sp) is at station 3 with a value of 0.575 ind., station 1 is 0.336, the lowest is at station 2 with a value of 0.088 ind. Size Distribution The smallest ranges between 40.17-52.19 mm and the largest ranges between 105.25 – 117.27 mm.
