Abstract

Saddang Watershed (DAS) as a large watershed in Sulawesi, rich in natural resource potential in the form of land, topography, slope, geology, soil, vegetation, climatology; rainfall, temperature, humidity, and sunshine. In maintaining and utilizing (watershed management) availability and water requirements for; humans, plants and animals. The availability and demand of water in watershed management requires the role of land in regulating agroclimatology and hydrology conditions. The water balance approach method used is SWAT (Soil and Water Assessment Tool) method of soil and water assessment tools, to determine the condition of availability and demand of water in an effort to maintain water flow conditions at all times (number and distribution) of Bendung Benteng irrigation system, which is capable of supply water for paddy field irrigation in two regencies of South Sulawesi’s paddy granaries namely Pinrang Regency and Sidrap Regency. According to the Schmidth-Fergusson climate classification, the type of climate in Saddang watershed area belongs to type C climate = slightly wet area with tropical rainforest vegetation, the average amount of rainfall ranges from 2.155 mm/year. This indicates that there is large level of rainfall every year and land use with a forest area of 676,39 or 26,41% of the watershed area, thus Saddang watershed is able to save tremendous amount of water supply. Based on the results of the water balance analysis using SWAT method, the amount of water available in the average watershed ; 3.133 mm year-1, the amount of water being flowed ; 1.040,9 mm, and stored as ground water ; 29,60 mm, as well as direct runoff ; 366,9 mm and flow coefficient of 0,45. Hence, there is 45% of the flow loss as surface stream and there is 55% of the flow stored in the watershed, and the model application is categorized as good both in conducting simulations and validating the flow discharge on Saddang River. Watershed processing classified as having good watershed conditions, because one indicator of a watershed's water performance can be seen from the river discharge fluctuation. River discharge fluctuations can be seen from the river regression coefficient (KRS), which is a number that shows ratio between maximum discharge (Qmax) and minimum discharge (Qmin). The highest discharge (Qmax) was 30.805 m³/sec while the lowest discharge (Qmin) was 994 m³/sec. The regression coefficient value (KRS) of Saddang River watershed was 26.650 m³/sec. Based on the results of the 2017 data analysis, the condition of Saddang watershed provides surplus value of 1.911.986 (m3 year-1), out of the total water availability of 2.155.273 (m3 year-1) minus the total irrigation water requirement of 243.286,50 m3 year-1, with the pattern of planting paddy-paddy-secondary crops (palawija). Therefore, Saddang watershed has the ability to store large amounts of water throughout the year

Abstract

Recently, coastlines in several areas of Indonesia have experienced erosion, which is quite worrying. Makassar City is one of 30 coastal cities in Indonesia that is estimated to be potentially affected by rising sea levels. As is the case in the Tanjung Bunga and Barombong Beach areas, the level of abrasion is very high. The beaches in these two areas have experienced a decline in coastline over the years, so they have moved far inland. This is caused by several factors, such as the influence of waves that occur in coastal waters, the influence of local winds, the presence of tides and the existence of coastal currents around Tanjung Bunga due to the lack of physical wave dampening structures, such as the lack of artificial structures/ buildings and mangrove forests. as physical protection of the coast. This study was conducted to identify changes in the extent of mangrove cover around the Barombong Shipping Polytechnic campus concerning data and information processing using a geographic information system (GIS). Based on the results of the data analysis, there has been a change in the extent of the mangrove ecosystem around the study location. This change in area can be seen from the upward trend over the last ten years. In 2013-2018, there was an increase of ​​30.38% or around 8.2 ha. In 2018-2023, there was an increase in the area of ​​7.36% or around 2.6 ha; in 2013-2023, there was an increase of ​​39.97% or around 10.8 ha.

Abstract

The availability of adequate water is one of the key factors in supporting increased food productivity, especially in areas that have large agricultural potential such as the Warsansom Watershed (DAS), West Papua. This research aims to predict water availability in the Warsansom watershed using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was chosen because of its ability to simulate hydrological processes, erosion and land use dynamics in a spatial-temporal manner. The data used includes rainfall, temperature, topography, soil type and land use patterns. The analysis results show that the average annual rainfall is 322 mm/year, with an annual average temperature of 26.49°C. The Warsansom watershed area is dominated by secondary dryland forest (78.69%) which contributes significantly to groundwater infiltration and recharge. Regional delineation resulted in 33 sub-watersheds with a total area of ​​144,280 ha, as well as 273 hydrological response units (HRU) which became the basis for identifying critical areas in water management. SWAT simulations reveal potential risks of surface runoff in areas with steep slopes (36.53%) that require conservation interventions to reduce erosion and sedimentation. This research recommends data-based strategies for optimizing water resource management, including improving irrigation infrastructure, developing cropping patterns that are adaptive to water availability, and mitigating the impacts of climate change. By utilizing SWAT simulations, it is hoped that food productivity in the Warsansom watershed can increase sustainably, supporting food security in the West Papua region

Abstract

This study aimed to evaluate the effect of aromatized thin-layer biopolymers on sensory perception in gel emulsions with spatial distribution of fat. An edible coating technique was used with Wijsman butter and cheese-cheese aromas to enhance fat perception without compromising other sensory attributes. Homogeneous gels with 20% fat content were applied with scented and unscented thin-layer biopolymers and then analyzed using the hedonic organoleptic method involving hardness, suppleness, color (transparency), and aroma parameters. The results showed that the scented thin-film biopolymer improved panelists' acceptance of fat aroma perception (score of 7.8), compared to the unscented biopolymer (score of 5.5). Panelists' acceptance of hardness, suppleness, and gel transparency did not differ significantly between the flavored and unscented treatments (values ranged from 7.1 to 7.9). This suggests that the addition of aroma can improve the perception of fat without affecting the physical quality of the gel. The use of aromatized thin-layer biopolymers can be an effective strategy to improve the sensory quality of low-fat food products, which is relevant in efforts to address the prevalence of overnutrition. This study contributes to the development of healthy food technology while maintaining consumer preferences for product texture and visuals.

Abstract

Composting organic waste is significantly gaining attention as a sustainable and environmentally friendly material. This is because the use of microorganisms or microbial consortia in the composting process can enhance the quality of compost. Therefore, this study aimed to examine the impact of microbial consortia on cow manure composting efficiency and nutrient content. The experiment was conducted at the Polinela Organic Farm, Department of Food Crop Cultivation. A randomized block design was used with multiple treatments combining fresh cow manure and microbial inoculants, including catalyst, Bacillus, and Trichoderma. The parameters evaluated were the effects of water content, pH, temperature fluctuations, and macronutrient levels on composting, including nitrogen, phosphorus, and potassium. The results showed that microbial consortia significantly improved composting parameters such as moisture retention and temperature as a function of higher doses?of the inoculum. The highest total nitrogen (3.6%) and potassium (1.67%) content were obtained from Trichoderma treatment,?while the highest phosphorus (0.47%) content was obtained from Bacillus treatment. This?implied that microbial consortia could improve the quality and availability of composted nutrients in addition to the effectiveness of agricultural waste management and soil fertility practices. However, more research should be conducted?to determine the optimal microbial mixtures for various conditions of composting and the quality of the best compost produced.

Abstract

Tofu dregs is an abundant waste from food production that is often not optimally utilized. In fact, tofu dregs have the potential to become an alternative food source if done in accordance with the ideal processing process and supported by the characterization of its nutritional content. This study aims to assess the chemical characteristics of tofu dregs flour through proximate analysis. The parameters analyzed included moisture content, ash, fat, protein, and carbohydrate by difference. Tofu dregs samples were obtained from tofu artisans in Bogor Regency, then dried, ground, and analyzed through the laboratory. The research was exploratory in nature using two replicates. The results showed that the moisture content of tofu dregs flour was 8.49 ± 1.34%, ash content 2.81 ± 0.19%, fat 7.86 ± 0.21%, protein 17.32 ± 0.27%, and carbohydrate by difference 63.53 ± 1.09%. The high protein content indicates that most of the soybean protein fraction is still left in the dregs. The low moisture content means the potential microbiological resistance of tofu bagasse flour during storage. These findings confirm that tofu dregs flour has promising nutritional value and it can be further developed as a sustainable ingredient for high-protein and fiber-rich food formulations. This will thereby contribute to waste reduction and functional food innovation.
