    Get PDF
    The soil in the Landfill area has generally been contaminated by various types of pollutants, including heavy metals, microplastics, ammonia, chloride, benzene, toluene, ethylene, ethylene benzene, and xylene (BTEX). At high concentrations, the pollutant can cause toxic effects on plants. The study aimed to evaluate the morphological and physiological conditions of C. argentea L. and C. rutidosperma D.C. after being planted on Randukuning landfill soil. Plant species were planted on landfill soil in the greenhouse for two months. Morphological observations (stem length, root length, and the number of leaves) and physiological (biomass of roots, stems, and leaves) were carried out on days 0, 3, 7, 14, 21, and 28 after planting on landfill soil. The results showed that C. argentea L. and C. rutidosperma D.C. did not show morphological and physiological effects. Both species can grow well on landfill soils. Therefore, these species can be potential phytoremediation agents

    Diatoms are widely used as bioindicators of water quality because of their short life cycle and sensitivity to changes of environmental conditions in waters.  One type of diatom that is used as a bioindicator is an epilithic diatom. Epilithic diatoms are one of the diatom microalgae communities attached to rock, so they are difficult to be carried away by currents. This study aimed to determine the type, composition, abundance, diversity, and dominance of epilithic diatoms found in the waters of the Brangkal subwatershed, and to determine the quality of water in the Brangkal subwatershed based on the epilithic diatom tropic index. Epilithic diatom samples were taken from 4 stations in the Brangkal subwatershed, Mojokerto Regency at the beginning of the dry season (July-August). The analysis carried out includes abundance, diversity index, dominance index, and Diatom Trophic Index (TDI). Based on the results of the study, 17 genera of epilithic diatoms were found, with the highest abundance of epilithic diatoms, including Navicula, Cocconeis, Nitszchia, and Gomphonema. The diversity index of all stations was in the medium category, with a value between 1.206 to 1.882. The lowest dominance index at station 1 was 0.167 and the highest was at station 4 with 0.373. In addition, the observed water quality is based on the Diatom Trophic Index (TDI), stations 1 to 3 are in a good category, and stations 4 are in a bad category.Â

    The production and demand of tilapia (O. niloticus) in some countries continue to increase but are not matched by good growth quality. Several methods have been used to increase growth, such as the use of synthetic hormones and radiation, however, the methods require such a high cost. Thus it needs to be investigated the potential replacement with natural prooduct. Papaya leaf contains papain enzyme thought to be able to improve the growth performance of fish body weight through the conversion of proteins into amino acids. The purpose of this study was to investigate the growth performance of tilapia (O. niloticus) fish that were given papaya meal (C. papaya) treatments. The concentrations pellet with papaya meal respectively T1(feed with 0 grams of papaya leaf meal), T2 (administration of papaya leaf meal with 1.25 g/kg feed), T3 (administration of papaya leaf meal with 1.75 g/kg feed), T4 (administration of papaya leaf meal with 2 g/kg feed), T5 (administration of papaya leaf meal with 2.25 g/kg feed). Parameters analyzed included: absolute length growth, absolute weight, specific growth rate, FCR survival rate and, water quality. The results showed that the highest weight growth of tilapia fed with the administration of papaya leaf meal was found at T4 of 21.23 grams. In the specific weight, the optimal treatment was found in T4 with a percentage of 20.97%. In the length growth of tilapia, it was known that the T1, T4 and T5 had highest lengths when compared to other treatments and the highest survival rate of tilapia (O. niloticus) was in the T2, T3, T5 treatments of 73%. The optimal FCR value was found in the T4 treatment of 1.14. Based on the results of the study, it can be concluded that the administration of papaya leaf flour can increase the growth performance of tilapia.Al-Nemrawi, N. K., Alsharif, S. S. M. & Dave, R. H.

    Chayote plants (Sechium edule) with monoecious characters require a pollination process. The pollination process requires pollinating agents to increase its productivity, one of which is insects. This research aimed to determine the diversity and abundance of insects pollinator on chayote plants. Observation of diversity and abundance used a scan sampling method. Pollinator insects observations were carried out in 3 time periods, morning, afternoon, and evening on male and female flowers. We measured environmental parameters such as temperature, humidity, wind speed, and light intensity. Eight species of wild insects pollinated chayote flowers, Apis cerana, Apis dorsata, Lasioglossum leucozonium, Polistes sagittarius, Phimenes flavopictus, Campsomeriella annulata, Lucilia sericata, and Musca domestica. The insect pollinators community had moderate diversity (1.23), a relatively dynamic community (0.59), and moderate dominance (0.62), with A. cerana, which had been the dominant insect pollinator with a relative abundance of 61.63%. Musca domestica and L. sericata were (0,58%) the least dominant insect pollinator with a relative abundance of 0.58%. This research concludes that the insects pollinator of chayote has a moderate level of diversity, relatively dynamic community, and average dominance

    Get PDF
    Gelodok or mudskipper fish are unique fish that have the ability to live in both aquatic and terrestrial areas. Some Indonesian who live in coastal areas use this fish for consumption. Types of mudskipper that are abundant in Indonesia are from the genera of Boleophtalmus, Periophthalmodon and Periophthalmus, where not all types have been studied for their nutritional content. The aim of this study was to analyze the content of Boleophthalmus boddarti and Periophthalmus variabilis. his study compared the nutritional content of the two types sampled from the Kaliwungu Kendal mangrove ecosystem and the Wedarijaksa Pati mangrove ecosystem. The two types of fish sampled were measured by morphometry which included body length, body width and body weight. Then the fish were analyzed for their nutritional content, namely carbohydrates using the Luff Schroorl test method, protein using the Kjeldahl method, fat using the Soxhlet method, iron using the AAS method, and phosphorus using the spectrophotometer method. The results showed that B. boddarti had a higher protein and iron content than P. variabilis . Meanwhile, P. variabilis had higher carbohydrate, fat and phosphorus content than B. boddarti. The difference was due to different feeding behavior, habitat, and types of food in B.boddarti and P. variabilis

    Basil plant (Ocimum americanum L.) is a fragrant annual plant widely cultivated by the people in Indonesia because it is useful and commercial. Previous research on salinity and drought stress in basil affects growth and development plant, cell turgor pressure, and the anatomical structure of the plant. However, research on the effect of alkalinity and drought stress in basil plants has not been carried out. Therefore, this study was conducted to determine the effect of variations in alkaline and drought stress on the growth and superoxide dismutase (SOD) content of basil plants. Alkalinity stress was carried out by variations of dolomite (D) doses which is divided into four levels, namely D1, D2, D3, and D4 (0 grams/pot, 100 grams/pot, 150 grams/pot, and 200 grams/pot) and variations of drought stress were divided into four types of field capacity, namely A1, A2, A3, and A4 (25%, 50%, 75%, and 100%). Parameters measured were plant height, leaf length and width, number of leaves, fresh and dry weight, SOD content, and environmental parameters. The growth of the basil plant (O. americanum L.) decreased after being given drought stress at a field capacity level of 25%, while the SOD content of basil (O. americanum L.) did not differ significantly but increased with the increase in dolomite doses and field capacity given

    Get PDF
    The problem in the management of blue swimming crab (BSC) fisheries is a decrease in stock that overlaps with an increase in fishing activities. This study aimed to analyze the ratio of spawning potential (SPR), reproductive potential, and reproductive productivity of BSCs taken from the Spermonde Islands. Spawning potential was analyzed using SPR, while reproductive potential analysis used the relative proportion of data between female, berried female and the average fecundity of each class size. The results showed that the BSC in Spermonde were growth overfishing and recruitment overfishing. The SPR of the BSC was estimated to be 7%, below the biological reference point. The highest reproductive potential index of berried females occurred in the group with a carapace width of 111-120 mm which contributed 36.84% of the total egg production. The value of reproductive productivity was 1.35 indicating a productive population. Current legislation allows the capture of BSCs with carapace sizes larger than 100 mm. Based on the data of this study, this size limit has the potential to eliminate 65.92% of the total egg production in the Spermonde Islands. To ensure the sustainability of BSCs in the Spermonde Islands, it is necessary to limit size by capturing BSCs >120 mm to protect the berried female and increase total egg production

    There is little documentation of bamboo species diversity and distribution in the Maluku Islands of Indonesia. This study aimed to provide information on the diversity and distribution of Maluku’s bamboo species. The research was conducted in March‒April 2021 at the Herbarium Bogoriense (BO), National Research and Innovation Agency. Herbarium specimens of bamboo in BO collected from the Maluku Islands (Provinces of Maluku and North Maluku) were studied alongside online scanned images of herbarium specimens. Bamboo species were re-identified and validated. A literature study was conducted to enrich the data. A distribution map of bamboo species in the Maluku Islands was compiled. Data were analyzed and presented descriptively. We built an identification key for the bamboo species in the Maluku Islands. There are 16 species and eight genera of bamboo in the Maluku Islands: Bambusa glaucophylla, B. maculata, B. multiplex, B. spinosa, B. tuldoides, B. vulgaris, Dendrocalamus asper, Gigantochloa atter, G. robusta, Neololeba amahussana, N. atra, Phyllostachys aurea, Racemobambos ceramica, Schizostachyum brachycladum, S. lima, and Thyrsostachys siamensis. These bamboo species were found across Maluku Province (Buru, Ambon, Seram, Kei Kecil, Kei Besar, Yamdena, and Tanimbar) and North Maluku Province (Ternate, Tidore, Halmahera, Obi, and Sula) at an altitude of 1‒1100 m above sea level in primary and secondary forests, limestone, peatland edges, city parks, and gardens
