Abstract

Citrus reticulata is a vital fruit crop in Nepal, where its demand is very high and has been produced as the main source of income in the hilly region. Nepal offers suitable topography, climate and soil for the profitable production of mandarins with great taste, precocity and high nutritive values. This study attempts to analyze the production trend, export and import, current scenario and prospects of mandarin in Nepal. The study employed a comprehensive review and synthesis of secondary data, including statistical records, publications from relevant organizations, and academic literature from 2001 to 2023, to analyze the production, marketing status, and prospects of mandarin in Nepal. The findings of the study shows that the production of mandarin is in increasing trend with an average annual growth rate of 7.04% from fiscal year 2019/20 to 2020/21 and cultivating area by 33.84 % from fiscal year 2019/20 to 2021/22. The study emphasizes the economic value of mandarins, especially in the mid-hill’s region, as well as their health advantages because of their fiber and antioxidant content. The yield of mandarin has decreased because of several issues, such as high investment costs, lack of adoption of improved technology, poor orchard management, diseases and pests, unstable prices and profit margins along with inappropriate market channels. Therefore, to strengthen this subsector, it is advised to focus on developing mandarin productivity through conventional mechanization, better adoption of technology, price intervention, market recognition, HLB management, establishment of storage and processing centers, and diplomatic relations for easy international marketing.

Abstract

The identity of coffee is significant for consumers mostly in relation to the characteristics of the end result product taste and quality. Robusta coffee varieties are widely grown by farmers in Bondowoso Regency in east Java, Indonesia using planting materials of unknown origin. The objective of this work was to identify the physical and chemical occurrence of Robusta cherries harvested from seven chosen genotypes grown in Curahpoh Village, Bondowoso. Samples of Robusta coffee cherries of seven selected genotype plants were harvested from Curahpoh Village, Bondowoso at three levels of maturity. Some physical and chemical factors were assessed as follows: sphericity, bean density, weight per bean, moisture content, total dissolved solids, to elicit differences in the genotypes. Analyzing the results obtained, the authors pointed to rather serious differences in these characteristics between various genotypes. The sphericity of fresh coffee fruits ranged from 0.82 to 0.93, with average density values between 1.00 and 1.11 g/cm³. The moisture content of green beans varied widely from 4.46% to 22.79%, while total dissolved solids ranged from 2.67% to 5.27%. These studies suggest the possibilities of genotypes selection in order to produce a superior genotype that would improve the quality as well as the marketability of Bondowoso Robusta coffee. These data contribute to the enhancement of the current agricultural practices, and the proposal of new varieties of coffee adapted to the specifics of their environment.

Abstract

The management of the Manggar Beach tourist area cannot be separated from obstacles related to the problem of waste generation. The problem of waste generation also results in the loss of aesthetic value and beauty of the beach, which decrease tourist interest in the tourism area. Therefore, efforts are needed to maintain the sustainability of the tourist environment by building tourist participation related to tourism waste management by applying the concept of the polluter pays principle so that tourist area more responsible for the waste they produce. Travel-based waste management can be done with a refund deposit mechanism. This study aims to (1) identify waste generation and the composition of the types of waste produced by tourists in the Manggar Beach tourist area; (2) analyze tourist perceptions regarding tourist-based waste management in the Manggar Beach tourist area; (3) measure the value of tourists' willingness to pay (WTP) on the amount of deposit refund in waste management in the Manggar beach tourist area. The result showed that plastic is the largest waste generation by tourist and 93% of tourists are willing to implement DRS for their waste. Thus, deposit refunds based on tourist’ WTP can cover operational costs for waste management in the Manggar Beach Area, so that DRS can be implemented in the Manggar Beach Area.

Abstract

Lake Towuti, one of the ancient lakes in Indonesia, is the second largest freshwater lake after Lake Toba. One of the endemic fish that live in Lake Towuti is the Matano Medaka fish (Oryzias matanensis Aurich, 1935). Due to land change, Lake Towuti's indicate is in threat of declining, which potentially have an impact on the endemic fish's habitat. The aim of this study is to identify the habitat characteristics of Lake Towuti. The data collected in this study includes temperature, pH, dissolved oxygen, and aquatic plants. Sampling was carried out in the morning, starting at 8:00 WITA and ending at 11:00 WITA at two different stations. Station selection was carried out based on differences in habitat, the presence of aquatic plants, and the presence of fish samples. Habitat characteristics at station one are marked by the number of water plants with the basic substrate types of sand, mud, and stones. In contrast, at station two, it is characterized by the absence of water plants and the basic substrate types of sand, rock, and gravel. Ecological aspects, including water physics and chemistry parameters, did not experience large fluctuations during the study period. The water conditions at each research station were not significantly different, so the water conditions were still good and supported the fish life in Lake Towuti.

Abstract

Seligi leaf (Phyllanthus buxifolius muell. Arg) is one of the medicinal plants that are traditionally used by the community. This plant can empirically treat several diseases, thanks to the content of antibacterial compounds such as flavonoids and terpenoids. The bacteria Pseudomonas aeruginosa and Staphylococcus aureus are the main causes of nosocomial infections. The purpose of this study is to examine the antibacterial activity of seligi leaf extract and fraction against Pseudomonas aeruginosa and Staphylococcus aureus bacteria, as well as to identify active compounds that have an important role in these antibacterial activities. The extraction process is carried out using the maceration method with 70% ethanol. The antibacterial activity test was carried out by the disc diffusion method, with concentration of 20, 40, 60, 80, and 100% for extraction, then for all fractions a concentration of 50 %. The test results showed that the extract had antibacterial activity against Staphylococcus aureus on 8 mg/disk loading disk with inhibition zone diameters of 10.33 ± 0.58 mm and 12.16 ± 1.41 mm, but no inhibition zones formed against Pseudomonas aeruginosa on all loading disks. The identification of compounds in seligi leaves using the KLT method showed that the extract contained phenolics, flavonoids, and terpenoids, while the ethyl acetate fraction contained phenolics and alkaloids. However, bioautographic tests do not indicate any antibacterial potential.

Abstract

Among frozen dairy products, ice cream is a product that is produced and consumed in large quantities. Coconut milk contains different types of fats, such as saturated fats, polyunsaturated fats, omega-3 fats, omega-6 fats, and monounsaturated fats. To improve the quality of ice cream in terms of taste, aroma, texture, and flavor, one can combine two ingredients, namely coconut milk and cashew milk. Cashews contain 40-57% fat and 21% protein. The purpose of this study is to measure fat content and antioxidant activity and determine the effect of cashew milk combination on fat content and antioxidant activity of coconut milk-based ice cream. This study is an experimental study with a factorial design in the form of a Completely Randomized Design (CRD). It consists of three treatments with different percentage compositions of coconut milk and cashew milk: A (60%:40%), B (50%:50%), and C (40%:60%). The experiment was conducted with two replications The parameters analyzed were fat content and antioxidant activity. The data obtained were processed using editing, coding, tabulating, and entry procedures. Furthermore, the data were analyzed using statistical tests in the form of One-Way ANOVA and the Kruskal-Wallis test to determine the effect of the combination of coconut milk and cashew milk on ice cream products. The results showed that there was a significant difference in the use of coconut milk and cashew milk on fat content with p = 0.000 (p ≤ 0.05) and antioxidant activity with p = 0.001 (p ≤ 0.05).

Abstract

Ice cream is one of the most popular foods, favored by people of all ages, from children to adults. Cow's milk is generally the primary ingredient for making ice cream. However, due to limited production and relatively high prices of cow's milk, alternatives such as coconut milk and cashew milk combinations are being explored. The quality of ice cream is influenced by total solids and melting rate. This study aims to determine the total solids and melting rate of coconut milk-based ice cream with the addition of cashew milk. This research is an experimental study using a Completely Randomized Design (CRD) with three treatments, varying the composition of coconut milk to cashew milk in ice cream production: 60%:40%, 50%:50%, and 40%:60%. The research procedure consisted of three stages:(1)Ice cream production;(2)Testing total solids in ice cream products;(3)Testing the melting rate of ice cream products Data were processed through editing, coding, tabulating, and entry. Statistical analysis was performed using a one-way ANOVA test. Results showed a significant difference in total solids among the treatments with varying ratios of coconut milk to cashew milk. Ice cream A had the highest total solids at 23.412%. However, the total solids values did not meet the quality requirements of the Indonesian National Standard (SNI). Regarding melting rate, no significant difference was found among the treatments. Ice cream A exhibited the highest melting resistance with an average value of 0.865. The melting rate values met the SNI quality requirements, with an average melting time of 45 minutes.

Abstract

Changes in land use are linked to climate change, resulting in the loss of carbon reserves due to decrease in vegetated land. Forests play crucial role in carbon storage. This research aims to determine carbon storage in the Toari Watershed, Southeast Sulawesi, in response to land use changes. The method uses GIS analysis to track changes in land use from 1991 to 2023, employing the SRTM Digital Elevation Model (DEM) for delineation. Carbon storage is calculated by multiplying the area of each land use by its respective carbon content value. The results of this research show that there have been significant land changes occurring from 1991 to 2023. Forest land is the land use with the most extensive changes, experiencing decrease in area of 7,181.20 hectares. This was also followed by increased mixed dryland farming use by 5,579.23 hectares, plantations by 1,994.28 hectares, residential land by 353.13 hectares, and open land by 640.85 hectares. From 1991 to 2023, land use changes had big impact on carbon stocks in the Toari Watershed. The largest decrease occurred in secondary dryland forests, leading to reduction of 741,530.7 tons C. Conversely, mixed agricultural land and plantations saw increases of 167,376.90 tons C and 125,639.60 tons C, respectively. Open land and residential areas also registered increases in carbon stocks. These findings highlight the influence of land use on carbon stock changes. The carbon stocks in the Toari Watershed decreased from 1,142,112.3 tons C in 1991 to 728,627.9 tons C in 2023 due to changes in land use.

Abstract

This paper aims to explore the key issues that govern water resource management in a particular District of East Tanjungpinang in Indonesia with particular reference to the reservoir systems on which the District relies heavily especially during the rainy seasons. Using both statistical analysis of water quality data and case-study / interview data, this research demonstrates that the district is exposed to climate variability, increasingly inadequate water infrastructure, and pollution threats. The research study shows that the reduction in water levels is being accompanied by poor water quality both due to poor infrastructure and increased pollution from industrial, agricultural and domestic sectors. The study provides new directions for water management, it emphasizes the need for enhanced more adaptive and resilient water management approaches that include technologies, infrastructure and green infrastructure. This also raises the call to develop better governance systems that increase opportunities for people’s participation, better compliance with the law, and the incorporation of indigenous concepts with contemporary management systems. Overall, it advances the understanding of water security concept and provides findings and suggestions for other regions in the world experiencing the same issues in the management of the freshwater resources under the conditions of climate change and growing urbanization.
