Abstract

D. magna as feed has advantages: easy to digest, the size is in accordance with the larval mouth opening, has 42.65% protein in the form of nutrition, contains a number of digestive enzymes, does not degrade water quality and can be cultivated in bulk. In this study, commercial catfish pellets fermented with probiotics were used as feed for D. magna. The probiotic that is often used in aquaculture is EM4 (Effective Microorganism 4). EM4 is able to play a role in increasing protein levels and with the right dose, EM4 becomes the main determining factor in growth productivity. The purpose of this study was to determine the good duration of EM4 fermentation in population growth of D. magna. This study is an experimental study (CRD), using D. magna as a test animal, with 5 different treatments. The results of the density of D. magna which were given different treatments gave different results. The highest density was found in treatment 3 and the treatment that had the lowest density was in treatment 5. The results of the Nonparametric test (Friedman-Test) showed significant results (P=0.00<0.05). Significantly different treatments were in treatment 3 and 5, while treatment 2 and treatment 4 had no significant difference. The results of the study the highest specific growth rate obtained was in treatment 4 of 0.223%/day, then followed by treatment 3 of 0.211%/day, while other treatments were relatively lower. Thus, feeding in the form of catfish pellets fermented with EM4 on the population growth of Daphnia magna gave a significant effect on treatment 3 and treatment 5 with the highest specific growth rate in treatment 4.

Abstract

Chromium can be found in 2 oxidation states, trivalent chromium (Cr3+) and hexavalent chromium (Cr6+) in environment. Trivalent chromium can be oxidized by manganese oxide to hexavalent chromium (Cr6+). The aim of the study was to determine the effect of Mn on the oxidation of Cr³⁺and plant growth of Tagetes. The study was conducted experimentally using a completely randomized design. The Tagetes plants grown in media with 2 treatment factors, namely Cr3+ (CrCl3) with 3 concentrations of 0, 100 and 500 mg/l) and Mn (MnSO4) with 4 concentrations of 0, 1, 5 and 10 mg/l. The plant growth and Cr6+ content in roots and shoots were measured to determine the effect and to detect the occurrence of Cr3+ oxidation. The addition of Mn in the media of Tagetes containing Cr3+ increased the Cr3+ oxidation process, indicated by the detection of Cr6+ in the roots and shoots of Tagetes. The highest Cr6+ content was found in the roots and shoots of Tagetes sp. treated with Cr3+ 500 mg/l and Mn 10 mg/l at 0.059 and 0.035 g/l, respectively. The interaction of Cr3+ and Mn treatments significantly affected the growth of Tagetes plants. Cr3+ and Mn at high concentrations increased plant height, root length, root and shoot dry weight. The interaction of Cr3+ and Mn at high concentrations inhibited the increase in the number of leaves of Tagetes.

Abstract

Ketersediaan air limbah rendaman kedelai yang melimpah dapat dijadikan sebagai pakan alternatif bagi D. magna. Peningkatan nutrisi dapat dilakukan melalui penambahan probiotik EM4. Tujuan penelitian ini adalah untuk mengetahui pengaruh perbedaan konsentrasi pemberian pakan air limbah rendaman kedelai terfermentasi dan periode waktu terhadap pertumbuhan D. magna. Penelitian dilaksanakan secara eksperimental di Laboratorium Akuakultur, Fakultas Biologi UKSW. Hasil pengamatan pertumbuhan D. magna tertinggi ditunjukkan oleh P3 (pakan terfermentasi 10 ml) sebanyak 922 ind/L, sedangkan perlakuan yang tidak mengalami pertumbuhan berarti ditunjukkan oleh P6 (pakan terfermentasi 80 ml) dan P1 sebagai kontrol. Konsentrasi terbaik ditunjukkan oleh P3 (pakan terfermentasi 10 ml). Pemberian air limbah rendaman kedelai terfermentasi sebagai asupan pakan D. magna lebih efektif dibandingkan dengan pakan tanpa fermentasi.The abundant availability of soy soaking wastewater could be used as an alternative feed for D. magna. Improving the feed’s nutrition could be done through by adding EM4 probiotics. This study aimed to determine the impact of differences in the concentration of fermented soy soaking wastewater feed and the growth period on the growth of D. magna.  The study was conducted experimentally in the Aquaculture Laboratory, Faculty of Biology UKSW. The observation revealed that the highest D. magna growth was demonstrated by P3 (10 ml of fermented feed) with 922 ind/L. In comparison, the treatment that did not experience significant growth was shown by P6 (80 ml fermented feed) with  P1 as the control.  The best feed concentration was  P3 (10 ml fermented feed). To conclude, the provision of fermented soy soaking wastewater as a D. magna’s feed intake was more effective compared to non-fermented feed intake.

Abstract

One of heavy metal pollutants in the soil that can be absorbed by the sorghum is chromium (Cr). The study was conducted to determine the growth response of Cr3+ stress of sorghum cultivars. Two chemical compounds Cr3+ and 3 level concentrations were exposed to sorghum cultivars. The research was conducted in two separate experiments i.e. during seed germination and early seedling development stages. The parameters measured were radicle/root length, seedling length, fresh weight, dry weight, and stress tolerance index (STI) value. The results showed that Cr3+ either in form of CrCl3 or KCr(SO4)2 significantly reduced the seedling growth of sorghum cultivars. The growth responses of sorghum cultivars toward Cr3+ stress showed differences both on stage of the germination and early seedling. Based on the average of STI value, four sorghum cultivars (Badik, Keris, Keris M3 and Numbu) were classified as very strong tolerant, 4 cultivars (Hegari, Mandau, Sangkur and Gambela) were categorized as moderate tolerant, two cultivars (UPCA and Selayer) were weak tolerant, and 2 cultivars (Kawali and Batari) were sensitive ones, under stress condition of Cr3+.The results of this study are expected to provide the scientific basis of the physiological and tolerance responses of sorghum cultivars toward Cr3+ stress condition.How to CiteKasmiyati, S., Santosa, S., Priyambada, I., Dewi, K., Sucahyo, S., Sandradewi, R.

Abstract

Increased production of reactive oxygen species or ROS is one of the common responses to a wide range of biotic and abiotic stresses. Increased production of ROS is outstripping endogenous antioxidant defense systems has been referred to as oxidative stress. Heavy metals are known to initiate ROS generation which is implicated as a oxidative stress. Cr is a toxic heavy metal that can generate ROS like H2O2 and O2 - which cause oxidative stress. In this study, chromium toxicity was studied to detect the oxidative stress on Sonchus oleraceus weed plants by the detection of superoxide anion and H2O2. Superoxide anion was detected by staining techniques with nitroblue tetrazolium (NBT) and hydrogen peroxide by Diaminobenzidine tetrahydrochloride (DAB) staining. Results indicated that the plants were grown in sand media generate the highest (0.89 A/g FW and 3.23 mol/g FW) than in soil media (0.23 A/g FW and 2.11 mol/g FW) superoxide anion (*O- 2) and H2O2 and soil containing textile sludge (0.18 A/g FW and 2.66 mol/g FW), respectively. At application of 10 mg Cr6+/L and 250 mg Cr3+/L, the production of *O- 2 and H2O2 in leaves of sonchus plants were significantly increased compared with the control plants. The highest production of H2O2 and *O- 2 were showed in the leaves of sonchus plants grown in sand media with Cr6+ application. In this study, either Cr3+ or Cr6+ caused oxidative stress in Sonchus oleraceus weed plants. The result also showed that sonchus plants esposed to toxic Cr can suffer from oxidative stress leading to reduction of its fresh and dry plants biomass. NBT and DAB in an appropriate probe and significant value for monitoring the formation of *O- 2 and H2O2 in plants.

Abstract

It is thought that the development of the Senjoyo River as a tourist attraction in Semarang Regency will cause changes to the natural ecosystem in the area, one of which is changing the structure of the existing gastropod community. This research is a quantitative analysis research using a survey method that aims to examine the structure of the gastropod community after the development of tourism activities on the Senjoyo River. Gastropod samples were taken from 10 different observation stations along the Senjoyo River, which are located at 7˚22'23"S and 110˚31'37"E. Observation station locations were determined by the purposive random sampling method, based on tourism activity density. The result showed types of gastropods that were found in the Senjoyo River namely, Sulcospira testudinaria, Tarebia granifera, Brotia costula, Thiara scraba, and Melanoides tuberculata with clustered distribution patterns (Id>1). Statistical analysis showed that location affected gastropod abundance (Asymp. Sig of 0.043), with the highest abundance found at station seven (45,11 individuals/m2). So station seven, with sandy and muddy substrate conditions, moderate current speed (0.257 m/s), and rarely found human activity, is the most suitable location to support the survival of gastropods in the Senjoyo River. Furthermore, the gastropod community structure indicates environmental changes at observation stations nine and ten, the locations where the most activities and construction of tourism facilities were found. That was indicated by the low diversity (H’= 0.00-0.01) and evenness (E = 0.00) index of gastropods, and there is dominance by Sulcospira testudinaria (C= 0.98-1.00).
