Abstract

Community timber plantation has an essential role as a source for the wood industry. One of the community timber plantations is located in Cibugel, Sumedang Regency, West Java. Lots of Gmelina arborea are planted in this community timber plantation because it does not need specific care and have a short cutting time. However, planting Gmelina in a community timber plantation leads to insect attacks on trees from different age groups, which could decrease wood production. Sustainable insect pest control efforts can be carried out by first understanding the structure of insect communities at different plant ages. Therefore, a study was conducted to compare the diversity of insect communities in plant age groups of 2, 4, and 15 years using the pitfall trap and sticky trap methods, supported by the hand searching method and microclimate data collection. In addition, plant damage caused by insects was also determined by analyzing the absolute and relative damage intensity. The results show that the dominant insect community in Gmelina age groups 2 and 15 years is Formicidae, which are generally classified as predators. Meanwhile, in the 4-year age group, the insect community was dominated by insects classified as herbivores, pests of G. arborea plants. These results align with the highest level of plant damage, namely in the 4-year age group.

Abstract

Rice agroecosystems generally experience two kinds of environmental stresses, i.e., a decrease in the heterogeneity of land vegetation types due to the development of settlements in the border zone and the excessive use of insecticides. Both of these factors are known to affect the structure of the arthropod community in rice agroecosystems. However, studies related to the effects of these two stresses in shaping the structure of arthropod communities have not been widely carried out, especially during the planting period in the rainy season. This study aims toanalyze the relationship between land cover heterogeneity and insecticide use with the taxonomic and functional diversity of arthropods in thealpha, beta, and gamma dimensions. The study was conducted during the rainy season (October–March) on four rice agroecosystem sites in Bandung, West Java. Data was collected 30 and 50 days after planting (DAP). Arthropod samples were identified, and their taxonomic andfunctional diversity was calculated using the Shannon entropy formula (D). In general, land cover heterogeneity was positively correlated withthe value of arthropod taxonomic and functional diversity, especially in the early vegetative phase of rice plants (30 DAP). In con- trast,insecticides (g/m2) were negatively correlated with the value of arthropod diversity. The composition of arthropod species locally was relativelythe same except in the rice agroecosystem with the lowest land cover heterogeneity and the highest use of insecticides. Additionally, thecoefficient value of the insecticide variable has more influence on the value of arthropod diversity than the variable coefficient of land coverheterogeneity.

Abstract

This research aims to assess the efficacy of three distinct types of aquatic plants, namely Nymphaea sp., Hydrocotyle sp., and Spirodela sp., in wastewater bioremediation from the laundry industry. The wastewater from the laundry industry contains a range of chemical substances that have the potential to pollute the surrounding environment. These include detergents, fragrances, and other chemicals that can cause pollution of the aquatic environment. The research method entailed the simultaneous planting of the three types of aquatic plants in controlled containers with the tested laundry wastewater. The temperature, pH, total dissolved solids (TDS), and dissolved oxygen (DO) of the laundry water effluent were measured before and after passing through the aquatic plant system. The results demonstrated that all three types of aquatic plants exhibited the capacity to reduce the concentration of TDS in laundry wastewater. The study revealed that there were notable differences in the effectiveness of various aquatic plant species in reducing TDS. Of the three plant species examined, Spirodela sp. demonstrated the greatest potential for reducing detergent concentrations, as indicated by a notable decrease in TDS.

Abstract

The water hyacinth plant (Eichhornia crassipes) is often used for the phytoremediation process. This is because water hyacinth is a plant that is easy to find, besides that water hyacinth is able to grow in polluted waters and is able to produce biomass. This study aims to analyze changes in pH, TDS, temperature and DO levels in domestic wastewater at the Sigay waterfall which was treated with Eichhornia crassipes (water hyacinth) plants with the addition of palm fiber and gravel over a treatment period of 3, 6 and 9 days in retention ponds, as well to determine the optimum time for phytoremediation of Eichhornia crassipes in retention ponds. crassipes (Water hyacinth) during the experiment. The experimental reactor consisted of 3 treatments, namely water hyacinth fiber palm+gravel for 3 days (T-H3), 6 days (T-H6) and 9 days (T-H9) with reactor without treatment as the control. Each reactor is filled with 3L of leachate. The reactor is left in the open and exposed to sunlight. Data were processed using the ANOVA test. The results show a value of P= 0.027 for pH, P=0.026 for temperature, P=0.003 for TDS and 0.066 for the DO test with a value of α=0.05, which indicates that if P0.05 there is a significant difference between each treatment.

Abstract

Biosorbents are biological materials used to remove pollutants from solutions passively. Papaya seeds are believed to be a biosorbent candidate because they contain SiO2, which has the potential to act as an adsorbent. Papaya seed adsorbent was made by adding H2SO4 as an activator and using Wantex red as the tested dye. This research aims to determine the potential concentration of papaya seeds as a biosorbent. The analysis used is qualitative, quantitative, and a significance test analysis. The method in this research uses 0.5 g (1%); 1.5g (3%); 2.5g (5%); 3.5 g (7%) of papaya seed biosorbent dissolved in Wantex red dye solution and analyzed using a UV-Vis spectrophotometer. The qualitative color results show contrasting color differences where the most transparent color is the dye added with 1.5 g and 2.5 papaya seed biosorbent, and the UV-Vis spectrophotometer absorbance results show that the best biosorbent mass is 1.5 g and 2.5 g with the highest absorbance power, namely 0.024 mg/g and 0.009 mg/g.

Abstract

Used cooking oil waste can be carcinogenic and toxic to living creatures in soil. Bioremediation is a way to treat used cooking oil-contaminated soil by using microorganisms that are safe for the environment. This research aimed to determine the effect of adding exogenous bacteria Bacillus sp. on the bioremediation process of soil contaminated with used cooking oil waste. Total Petroleum Hydrocarbons (TPH) measurement and effectiveness of Bacillus sp. in degrading hydrocarbons was calculated in this study. The results showed that Bacillus sp. has the ability to rapidly degrade used cooking oil TPH and increased the effectiveness of bioremediation in soil.
