Abstract

Indonesia has various types of vegetation which are used as natural coagulants or biocoagulants. Coagulants can be divided into chemical coagulants and natural coagulants (biocoagulants). Biocoagulants are more environmentally friendly and can be obtained from natural ingredients, both animals and plants, one of which is Moringa seeds. Moringa seeds or with the Latin name Moringa oleifera are a type of plant from the Moringaceae family. From several previous studies, Moringa seeds were used as a more economical and environmentally friendly wastewater treatment method. Moringa seed biocoagulant in powder form is made from ripe and old moringa seeds and contains less than 10% water. Moringa seed biocoagulant contains 4αL-rhamnosyloxy-benzylisothiocyanate and is a determinant of coagulation effectiveness. This active substance is able to absorb pollutants in waste water. This research aims to treat tofu waste with moringa seed biocoagulant in reducing pollutant parameters, namely TSS (Total Suspended Solid) and COD (Chemical Oxygen Demand). Results of the removal of pollutants from moringa seed powder biocoagulant in tofu waste water the efficiency value obtained for each TSS parameter, and the COD for the TSS parameter is 54.4%. and for the COD parameter of 14.6%, it can be concluded that the efficiency value for each parameter still does not meet the effectiveness value.

Abstract

Laboratory is one of the generators of hazardous liquid waste derived from chemicals used in practice and research. The waste is very dangerous when discharged into the environment because of the pollutants it contains. Therefore, it is necessary to treat the waste before it is disposed of to minimize the impact of pollution caused by the waste. The study aims to compare the effectiveness of zeolite adsorbents and activated carbon in reducing COD, TSS, and Cr heavy metals. Waste treatment is carried out by coagulation and adsorption methods. The adsorption process is performed using two types of adsorbents: zeolite and activated carbon. This study was carried out by variing the mass of the adsorbents at the time of complaining for 120 minutes in batches. Variations in the masses of the used 3, 5, 7, and 10 grams of adsorbenes. The results of the study showed that the more adsorbanes used, the higher the reduction of pollutant levels. The use of 10 grams of activated carbon adsorbents can reduce TSS pollutants levels of 92%, COD 95%, Cr 65%, and pH 5,0-6,38.

Abstract

Liquid waste from the tofu industry contains various organic and inorganic substances which can reduce water quality. This research aims to assess the effectiveness of Poly Aluminum Chloride (PAC) as a coagulant in reducing pollution parameters in liquid waste from the tofu industry. In this study, experiments were carried out with three variations of PAC doses (75 mg/L, 150 mg/L, and 225 mg/L) and different stirring times (10, 15, and 20 minutes) using the jar test method. The jar test method is a standard laboratory technique used to determine the optimal dose of coagulant needed to remove turbidity from wastewater. The results show that a PAC dose of 225 mg/L with a stirring time of 20 minutes is the optimal condition, reducing Total Dissolved Solids (TDS) from 996 ppm to significantly lower. The initial conductivity of 1971 µs decreased after the addition of high doses of PAC and longer stirring times. The pH parameter increased from 4 to 5. Although still acidic, this increase indicates a reduction in acidity, which can be useful in reducing negative impacts on the aquatic environment. The color of the wastewater becomes clearer and the odor decreases, indicating a decrease in organic compounds and dissolved substances. The temperature remained stable at 28ºC before and after treatment. This research confirms that PAC is effective in improving the quality of wastewater from the tofu industry through the coagulation mechanism, producing cleaner and clearer water with a significant reduction.

Abstract

This study aims to analyze CO concentration, CO concentration rate, and its distribution pattern in the Palmerah Three-Way Intersection area of Jambi City. The research method used is descriptive quantitative with measurements at three sampling points (Points I, II, and III) each 100 m from the Traffic Signal Device (APILL). The measurement results showed the highest CO concentration of 8,991 µg/Nm³ occurred at Point II on Tuesday Afternoon, Points II and III on Thursday Afternoon, and Points I and II on Saturday Afternoon. The lowest concentration was recorded at 2,247 µg/Nm³ at Point II on Tuesday Morning. These results indicate that traffic congestion contributes significantly to the increase in CO concentration in ambient air, so mitigation efforts such as traffic management and increasing green open spaces are needed to reduce the impact of air pollution in urban areas.

Abstract

Carbon dioxide (CO₂) is the main contributor to global warming and climate change. Human activities in residential areas significantly increase CO₂ emissions. Green open spaces such as urban forests play a vital role in absorbing this gas through photosynthesis. This study aims to measure the concentration of CO₂ in the areas of Muhammad Sabki Urban Forest and Grand Kenali Residential Complex, as well as to map its spatial distribution using Geographic Information System (GIS) with the Inverse Distance Weighting (IDW) interpolation method. Data collection was conducted over three days, during three time periods (morning, noon, and afternoon), at four sampling points spaced 65 meters apart. The results show a significant difference in CO₂ concentrations between the two areas, with residential zones showing higher levels than the urban forest. Spatial visualization through digital maps revealed a distribution pattern consistent with the level of human activity and vegetation cover in each area. This research provides valuable insights for emission reduction strategies and sustainable spatial planning. Keywords :    Carbon Dioxide (CO₂), Geographic information system (SIG), IDW, Residental area, Urban ForestABSTRAKEmisi karbon dioksida (CO₂) telah menjadi penyebab utama pemanasan global dan perubahan iklim.

Abstract

Domestic wastewater was collected from a drainage system on Soekarno Hatta Street, Kalibalau Kencana, Kecepatan District, Bandar Lampung City, with a high Chemical Oxygen Demand (COD) content of 4,867 mg/L. If the wastewater is discharged directly into water bodies, it can reduce the availability of dissolved oxygen, potentially disrupting the survival of aquatic organisms. This research aims to determine the effect of contact time on the reduction of COD levels in domestic wastewater, the effect of fly ash adsorbent both activated and non-activated on the reduction of COD values, and its impact on other parameters according to domestic wastewater quality standards. Fly ash was activated using 6M NaOH and heated at 160°C for 1 hour. The adsorption process was carried out with varying contact times of 30, 60, 90, 120, and 150 minutes, using both activated and non-activated adsorbents with masses of 1.5 and 3 grams. The results of this study showed that the adsorption test with the activated adsorbent with masses of 1.5 and 3 grams reached optimum times of 90 and 60 minutes, respectively, with percentage reductions of 98.78% and 99.03%. In contrast, for the non-activated adsorbent with masses of 1.5 and 3 grams, optimum times occurred at 150 minutes, with percentage reductions of 95.64% and 90.79%, respectively.

Abstract

Carbon monoxide (CO) is a compound that has no smell, taste or color. The compound carbon monoxide (CO) originates from vehicle exhaust emissions from incomplete engine combustion, when exposed it will have an impact on disrupting the path of oxygen binding to hemoglobin in the blood. The Mendalo Darat road is one of the busiest roads in Jambi Province, so it is prone to traffic jams due ti the dense mobilization of motorized vehicles. This can result in a decrease in ambient air quality due to the concentration of carbon monoxide (CO) compounds. This study aims to determine the quality of ambient air in the parameters of carbon monoxide (CO) on the Mendalo Darat highway and the resulting emission rate. Based on the research results for 3 days, namely Sunday (Weekend), Monday, and Tuesday (Weekday), it shows that the highest density is on Tuesday morning which is 17,994 units. Meanwhile, the lowest vehicle volume was on Sunday afternoon point III with a vehicle volume of 6.576 units. The results showed that the highest carbon monoxide (Qco) emission rate on Sunday was at point I in the afternoon of 97.114 µg/m.s, at point II in the afternoon that was 52.665 µg/m.s, and point III in the afternoon wa 52.644 µg/m.s. on Monday, the highest emission rate of carbon monoxide (Qco) was at point I in the afternoon of 106.830 µg/m.s. followed by point II in the afternoon, which was 86.795 µg/m.s on Tuesday, and point III, which was 86.749 µg/m.s. on Tuesday, point I with the largest carbon monoxide (Qco) emission rate was 114.290 tn the morning, followed by point I, which was 109.601 in the afternoon
