Abstract

Orange-footed scrubfowl (Megapodius reidwardt) are protected species and need to be preserved. Orange-footed scrubfowl (Megapodius reidwardt) are terrestrial birds that build nests on the ground. To maintain its sustainability, it is necessary to have knowledge about the characteristics of orange-footed scrubfowl nests. Kerandangan Natural Tourism Park is one of the places where orange-footed scrubfowl are found, but until now there is still no information about the characteristics of orange-footed scrubfowl nests. So this study aims to analyze the characteristics of orange-footed scrubfowl nests in Kerandangan Natural Tourism Park. The method used in this research is descriptive exploration, the research variables include physical parameters of the nest, environmental parameters of the nest, chemical parameters of the nest mound and plant vegetation around the nest. The results showed that the diameter of the nest ranged from 400-590 cm with a nest height of 85-154 cm, the number of laying holes ranged from 1-3 holes and the soil texture class of the nest mound consisted of sandy loam and loam. Environmental parameters obtained average temperature outside the nest 27,9oC, average temperature inside the nest 28,6oC, average humidity outside the nest 80,3%, humidity inside the nest 81,2% and light intensity ranged from 98,1-834,1 lux in the morning, 437,8-4014,8 lux in the afternoon, and 45,7-653,8 lux in the afternoon. Chemical parameters obtained organic matter content ranged from 1,4%-3,2% and pH ranged from 6,8-7. Vegetation that had the highest INP in each nest was Voacanga foetida, Inga edulis, Artocarpus elasticus, and Bambusa bambos, these plant species act as materials for building nest mounds and potentially as food for orange-footed scrubfowl.

Abstract

Stroke is the third most normal sickness after coronary illness and disease and is the main source of handicap on the planet. The incidence of stroke in Indonesia is very urgent because the number of stroke sufferers is increasing day by day and ranks first in Asia. This study aims to determine factors related to the quality of life of stroke patients at Ibnu Sina Hospital Makassar. The design of this study is descriptive correlative with a cross-sectional approach. The statistical tests performed on 30 stroke patients at Ibnu Sina Hospital Makassar revealed two factors related to quality of life—age (= 0.034), medical history (= 0.011), and nutritional status (= 0.057)—and two factors that were not related to quality of life—gender (= 0.027 =) and nutritional status (= 0.057). The end is that orientation isn't connected with personal satisfaction, yet age and clinical history are connected with the personal satisfaction of stroke patients at Ibnu Sina Medical clinic Makassar.

Abstract

Stunting is one of the focuses of the Sustainable Development Goals (SDGs), which includes the secondary goal of ending hunger and all forms of malnutrition. Stunting is a serious chronic nutritional problem throughout the world, especially in developing countries. Stunting occurs when a child does not get enough nutrition during his growth period and can result in impaired physical growth and cognitive development. An effective solution to overcome stunting is to increase your intake of protein and important nutrients through additional food. Catfish has been proven to be a potential nutritional raw material for overcoming stunting because it is rich in protein and nutrients. The aim of this research is to analyze in detail the nutritional content of catfish extract which is considered a superior food ingredient for overcoming stunting. This research used a purposive sampling method by measuring proximate tests, total polyphenols and antioxidant activity (DPPH). It is hoped that the results of this research will provide further insight into the nutritional value of catfish extract and its potential in improving the nutritional status of stunted children. The results showed that catfish extract had a water content of 4.97%, ash content of 8.91%, fat content of 29.87%, protein content of 48.85%, carbohydrate content of 7.40%, total polyphenol content of 0.12% and antioxidant activity with an IC50 value of 4.9724%. This research concludes that catfish extract has the potential to improve nutrition for stunted toddlers.

Abstract

Sumatra has a very large forest area so it has great potential to become a place for honey bee cultivation. The various honey produced has different characteristics depending on the source of the nectar. Research on sensory testing of Sumatran forest honey appears limited, with studies focusing more broadly on honey quality and properties. It is necessary to collect data on the sensory profile of Sumatran forest honey as a database that will help control the quality and ensure the authenticity of the honey. The purpose of this study is to determine the sensory profile of five types of Sumatran forest honey traded around Lampung Province. The method used a scoring test on color, aroma, taste, and viscosity. 30 trained panelists were used who had been selected and trained before conducting sample assessment. Data processing using ANOVA and further test Duncan Multiple Range Test (DMRT) with SPSS 27.0 software. The results showed that the five types of Sumatran forest honey tested had the same viscosity but had different color, aroma, and taste profiles. These distinctive and unique characteristics can enrich the biodiversity in Indonesia so it needs to be optimized for its benefits and preserved.

Abstract

The traditional agroforestry industry is part of the Forestry and Other Land Use Net Sink 2030 (FOLU Net Sink 2030) strategy for low carbon development and climate resilience in Indonesia. This study aims to estimate the value of biomass, carbon stock, and carbon sequestration in traditional agroforestry systems in Rimbo Panjang Village, Kampar. Six plots (each measuring 20 x 20 meters) are used; three of the plots are 15 years old and three are 9 years old, respectively, for the conventional agroforestry system.  Biomass, carbon stock and carbon sequestration were estimated at the tree, pole and sapling levels.  Biomass calculations used allometric equations based on diameter at breast height (DBH) data. The results showed that carbon sequestration in Dusun 2 (618.2 tons/ha) was greater than in Dusun 1 (399 tons/ha), with an average carbon sequestration in both dusun of 508.6 tons/ha.  Trees contribute the highest value of biomass, carbon stock, and carbon sequestration, which is 74%, The difference in the value of biomass, carbon stock, and carbon sequestration in traditional agroforestry systems in Rimbo Panjang Village is significantly influenced by the average stem diameter. The various trees that make up traditional agroforestry in Rimbo Panjang Kampar, which is generally in the yard, should ideally be maintained and developed because of their high carbon sequestration potential.

Abstract

Abalone shells (Haliotis sp.), known as seven-eyed shellfish, are a type of gastropod. Abalone shells have high economic value accompanied by high market demand. The selling price of abalone reaches Rp. 250,000 (shells and meat). To optimize abalone cultivation activities with a long growth time, one method is needed for cultivating abalone shells in KJA (Floating Net Cages), namely using a tiered system in one hanger with different depths, namely 1m, 2m, 3m, 4m and 5m. so that it can increase land efficiency in cultivation activities. The aim of this research is to evaluate and analyze the effect of depth on the growth and survival rate of abalone shells (Haliotis sp.) using a multilevel system. The method used in this research was a Completely Randomized Design (CRD) experimental method with five treatments and three replications. The results of the research conducted showed that the results of the anova test on absolute length growth, specific length growth rate, absolute weight growth, specific weight growth rate, and survival of abalone shells (haliotis sp.) showed that they had no real influence (>0.05) on the maintenance of abalone shells. Based on the research results, it can be concluded that using a tiered system at different depths does not have a real effect on the growth of abalone shells because the water quality conditions at a depth of 1-5 meters are optimal so they can support the growth of abalone shells.

Abstract

Plankton are organisms that are found living floating in the water, that move passively so they are easily carried by currents. Plankton includes two large groups, namely phytoplankton which is similar to plants and zooplankton which similar to animals. One of important benefits of plankton is an indicator of biological conditions. This research aims to determine the types of plankton and their abundance at Situ Gintung, South Tangerang City. Sampling was conducted at three points area. The samples obtained were then observed and counted under a microscope and identified using web determination. Data were analyzed using plankton diversity and abundance formulas. The research results found phytoplankton species, such as Nitzschia sp., Navicula sp., Coscinodiscus sp., Synedra sp., Staurastrum sp., Scenedesmus sp., Coelastrum sp., Oscillatoria sp., Spirulina sp., Peridinium sp., and Phacus sp. The zooplankton obtained were Nauplius sp., Eudiaptomus sp., Polyarthra sp., Brachionus sp., Trichocerca sp., and Lecane sp. The average value of the phytoplankton diversity index is 0.543 and zooplankton is 1.043. The average phytoplankton abundance index obtained is 18,808,334 ind/L and zooplankton is 32,766 ind/L. Based on the results obtained, it was concluded that there were 11 types of phytoplankton and 6 types of zooplankton. The phytoplankton diversity index is in the low category and zooplankton is in the medium category, while the phytoplankton and zooplankton abundance index are in the medium to high category, but phytoplankton abundance is more dominant than zooplankton.
