Villagers tried to cultivate catfish and tilapia, but it did not work because they died. Water as a medium for fish farming activities is an important factor that must be considered. Water quality in waters can affect aquaculture activities and fish growth. The study was conducted to determine the water quality (physics and chemistry) in the Komering River tributary as a basis for the cultivation environment. The research was conducted in the Komering tributary of Pangkalan Gelebak Village, Banyuasin Regency, in September, October, and November 2019. The sampling point is determined using a purposive sampling method in four sampling points. The temperature measurements range from 27-32.7ºC, depth 0.4-9 m, brightness 0.2-1.1 m, and turbidity 12.62-69.2 NTU. Only the depth of the four physical parameters is unsuitable for cultivation activities. During the dry season, the water depth between the riverbed and cage nets does not reach 1m. Chemical parameter measurement results; dissolved oxygen 1.7 – 7 mg/l, pH 6.5 – 7, alkalinity 34 - 46 mg/l CaCO3, nitrate 0.892 - 2.278 mg/l, nitrite 0.032 - 0.217 mg/l, ammonia 0.02-0.398 mg/ l and ortho-phosphate 0.054-0.283 mg/l. The value of nitrate, ammonia, and orthophosphate indicated high values so than unsuitable for fish farming activities. Agricultural activities around creeks and domestic waste disposal are causes of poor water quality.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131327228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sentani Snakehead Fish is one source of animal protein that is very important for the community around Lake Sentani. The population of the Sentani Gudgeon Fish species is at a crucial level. The issue could be affected by environmental pressures, continuous catches, competition with introduced species from outside Papua, intensive predation systems, and imbalances in ecological systems. The condition made a decline in population size until it became extinct. Gudgeon Sentani fish is the main target of catching in the lake. This condition significantly affects stock, size when first captured, population decline, reproductive cycle, and average catch. Until now, data and information on the growth of snakehead fish as the basis for fisheries management in the waters of Lake Sentani are not widely known. Considering the importance of preserving the native species of Lake Sentani, especially the Snakehead Fish, efforts to manage the fisheries in Lake Sentani's waters are urgent. This research was conducted in March - October 2020, located at Lake Sentani. The specimens were obtained from the catch of fishers with various gill nets and chopsticks. Enumerators or field assistants assisted the recording of the number and measurement of the total length of fish caught by fishermen daily. The results of the analysis showed: asymptotic size (L?) 46.20 cm, growth coefficient (K) 0.29, the total mortality rate (Z) 0.80 per year, natural mortality (M) 0.74 per year, the mortality rate due to fishing (F) 0.06 per year and exploitation rate (E) 0.075 per year.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121655447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine the effect of Formula Application and dosage of complete compound fertilizer on the growth and yield of chili plants. This study used a factorial Randomized Block Design (RAK) with nine treatment combinations and three replications, each treatment consisting of 3 plants. The combination of these treatments used two Complete Compound Fertilizer Formulas (P). Formula 1 (P1) Complete Compound Fertilizer Pril (PMLP), 2 (P2) : Complete Compound Fertilizer Tablets (PMLT), and 3 (P3) as a control mixture of single fertilizer Urea, SP 36, and KCL ( 1:1:1). The second formula is fertilizer dosage (D) which consists of three levels, namely D1 (30 g fertilizer/plant), D2 (40 g fertilizer/plant), and D3 (50 fertilizer/plant). The variables observed in this study were plant height, number of fruit per plant, fruit weight per plant, dry weight of plant stover. Based on the results of the research that has been carried out, it is concluded that the treatment of Complete Compound Fertilizer Formula (P) has a very significant effect on all observed variables, namely: plant height, number of fruits per plant, the weight of dry root, and weight of fruit per plant. While the Fertilizer Dosage (D): 30, 40, and 50 g did not show a significant difference in the results for all observed variables, and the interaction between the two did not show significant differences in all observed variables.","PeriodicalId":198121,"journal":{"name":"Journal of Global Sustainable Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130878024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify the plankton community, i.e., abundance, diversity index, dominance index, similarity index between stations, and describe pollution level conditions based on saprobic coefficient. Sampling in this study using purposive random sampling method at five observation stations with three sampling locations, respectively. The physical and chemical parameters of the waters include temperature, brightness, current speed, pH, Dissolved Oxygen (DO), nitrates, and phosphates. The composition of plankton consists of 47 Genera derived from 8 Classes, with a total abundance value in March ranging from 13-27 ind./L, and the total value of abundance in April 2018 has a range of values of 12-21 ind./L. Plankton diversity index values in about 1.87-2.98 indicate the stability of the moderate biota community. Based on the index of plankton dominance with a range of 0.05-0.21, no species dominate other species or D = 0(<0.5). In contrast, the index of plankton similarity between stations shows the communities between stations are relatively different (<50%). The water quality of the Ogan River based on saprobic coefficients is light to very light.
