Abstract

Adiwiyata School program is unable directly build the student’s environmental care character. Therefore, it is necessary to evaluate the students’ environmental care character at schools that won the Adiwiyata Award. This study aims to evaluate the environmental care character of students at Adiwiyata School. This study used a mixed-method, which combines quantitative and qualitative descriptive methods. The research sample was taken using the purposive sampling technique where the researcher took 110 students as the research sample. There are 3 (three) indicators used to evaluate students' environmental care character. The first indicator is the environmental cleanliness concern which showed 89.88% of students gave a positive value response. The second indicator is the knowledge of waste management which showed 90.07% of students gave a positive score response, and the last indicator is the knowledge about reforestation and natural resource management which showed 82.62% of students gave a positive score response. Based on the three indicators used, the overall response was a positive value of 75%. In accordance, the results of the study show that the average value of positive responses was 88.08%. Thus, it can be said that the environmental care character of students at SMPN 19 Palembang is in the very good category.

Abstract

The high price of toman fish (Channa micropeltes Cuvier.) in the market is one of the reasons for the need for toman fish farming activities.  However, the expensive price of commercial feed causes the cost of cultivation to be high.  Effective and efficient feeding can reduce feed costs.  Satisfaction is done so that the stomach is emptied in an uncharacteristic time, so it is expected to increase the appetite of Toman Fish.  This study aims to determine the effect of grazing time on the growth of toman fish. This research was conducted in the Wet Fisheries Laboratory, Faculty of Agriculture, Muhamadiyah University of Palembang.  From September to November 2021.   The research method used is an experimental trial with a Non-Factorial Complete Randomised Design. Treatment factors include P1 (No gratification/control), P2 (1 day fasting 4 days fed), P3 (1 day fasting 3 days fed), P4 (1 day fasting 2 days fed), and P5 (1 day fasting 1 day fed). The changes observed were weight growth, length growth, and survival rate (SR).  The treatment of 1-day of fasting and 1 day fed to toman fish (Channa micropeltes Cuvier.) is the best treatment for length growth (3.35 cm), weight (11.06 grams), and survival (89%).

Abstract

The existence of tree vegetation planted in coffee plantations as shade trees is believed to have a positive influence on the growth and production of coffee plants. This study aims to analyze the diversity of coffee plant vegetation in three age classes planted inside and outside protected forest areas included in the administrative area of North Dempo and Central Dempo Districts, Pagar Alam City, South Sumatra Province. The results of observations and calculations of Value IVI found that Albizia sumatrana was the dominant species in all coffee plantations at various age levels. The IVI values of Albazia Sumatrana in coffee plants aged < 5 years were 157.32 (inside PF) and 720.92 (outside PF), in coffee plants aged < 10 years, were 84.30 (inside PF) and 155.51 (outside PF), while in coffee aged > 10 years is 75.46 (inside PF) and 95.92 (outside PF). Assessment using the Shanon Index and Simpon Index showed the same results; coffee plantations at all age levels had a moderate diversity index, except for vegetation in coffee plantations aged < 5 years which were outside protected forest areas and had low diversity index values. Through the availability of this information, it is hoped that it will be used as initial information for selecting vegetation types that will be used to support restoration activities in areas around protected forests.

Abstract

Rice productivity can be increased by expanding the number of inputs or through the application of new technologies. Demonstration Farm (Demfarm) is one of the methods used for the adoption of agricultural technology according to the developed potential commodities. This study intended to determine the financing model for lowland rice located in Sungai Dua Village, Rambutan District, Banyuasin Regency based on the variety used in relation to rice field construction. The method used was a trial or experiment. This research was conducted on an outdoor laboratory area of the University of South Sumatra in collaboration with partners (IPB University, PT ATS Inti Sampoerna, PT PUSRI, BPTP). There are 3 superior varieties used consisting of IPB3S, Inpari 32 and Ciherang covering an area of 6 hectares in 2021. The population of this study are all farmers who participate in the new rice field printing program that will be formed into the Rice Estate Community (KEP), as many as 15 people who own land and farm laborers by using the census method considered that the entire population as the sample. The analysis used is qualitative and quantitative analysis. The results showed that the income earned by the University of South Sumatera in the first period was Rp.(7,3977,235)/0.5 Ha/MT for the IPB3S variety, Rp.(6,638,485)/0.5 Ha/MT for the IPB3S variety. Inpari 32 and p(5,949,235) /0,5 Ha/MT for Ciherang variety. Constraints faced were soil pH <4, pH of water between 2-3 and still contains pyrite, shallow swamp land type endanger to flooding, inappropriate irrigation and land conditions that still had a lot of tree trunks left. The feasibility analyses used were the B/C ratio and R/C ratio, the results of which showed that based on superior varieties the B/C ratio for the IPB3S variety was (0.80), the Inpari 32 variety was (0.79 ) and Ciherang variety was (0.74). While the R/C ratio in the IPB3S variety was 0.20, the Inpari 32 variety was 0.21 and the Ciherang variety was 0.24. The B/C ratio and the R/C ratio value < 1 indicated that the activities of this model of financing of new rice farming for the first planting period were not feasible due to natural hazard, technical and inappropriate  facilities. This research showed that the better resistance and adaptation were shown by the Ciherang variety.

Abstract

Flash flood is one of the natural disasters that currently happens a lot in Indonesia. Java Island is one of the largest archipelagoes in Indonesia and has the highest incidence of flash floods. Several efforts were conducted to anticipate and mitigate flash floods in Java Island, including an early warning system, preparing safety equipment, building evacuation route signs, and monitoring watersheds. Through the dataset of Village Potential 2018, this study aims to explore the effectiveness of flash flood mitigation in Java Island using the R programming language. The stages of research carried out in this study are data preprocessing, including selecting, recoding the variables, exploratory univariate, bivariate, and multivariate data analysis. The results showed that the fatalities of flash floods often occurred in areas with plains surface, especially in West Java and East Java, followed by the topography of Central Java on the hills and the valleys in Banten. In addition, the most effective disaster mitigation established in Java Island is safety equipment and the construction of evacuation route signs compared to other disaster anticipation efforts.

Abstract

Nutrients (C, N, and P) can affect the growth and biochemical content of Arthrospira platensis. Ethanol can be a potential carbon source compared to glucose and acetic acid. Glycerol is also potential as a carbon source for the growth of Arthrospira platensis. This research was carried out from June to July 2021 at the Aquaculture Laboratory and Experimental Pond Laboratory of the Aquaculture Study Program, Sriwijaya University. The research method used Completely Randomized Design (CRD) factorial with 2 factors consisting of the first factor with 3 treatments and the second factor with 2 treatments and 3 replications. The inoculant was cultured in liquid fertilizer technical F/2 media for culture stock as initial inoculum with a density of ± 1.0 g L-ˡ. Parameters observed were the density, the specific growth rate, and water quality. The results showed that M1S3 treatment had the highest density with a value reaching 4.95 g L-1 and the highest specific growth rate of 0,33% per day. ANOVA test result showed that the addition of carbon sources in the culture media of fertilizer and technical waste had a significant effect (P<0.05) on the growth rate of Arthrospira platensis. The water quality parameters of each treatment were suitable for Arthrospira platensis culture.
