Abstract

Agricultural activities still involve the use of synthetic pesticides to support the increase of their products. On the other hand, the use of synthetic pesticides such as organochlorines and pyrethroids may contribute to the decline of aquatic ecosystem health due to the accumulation of their residues in sediments and organisms. The current study aimed to assess the levels of organochlorine and pyrethroids pesticide residue in endemic fish and sediment from Lake Singkarak. Bilih fish and sediment samples were taken in June 2021 at ten (10) sampling sites in Lake Singkarak. The samples were extracted and analyzed by gas chromatography. Seven organochlorine compounds were measured, including aldrin, endrin, dieldrin, DDT, heptachlor, lindan, and endosulfan. Meanwhile, three compounds chosen from the pyrethroid group, cypermethrin, permethrin, and α-cypermethrin, were also measured. Four organochlorine compounds, aldrin, dieldrin, DDT, and endrin, were detected in bilih fish in three different sites. Dieldrin had the highest concentration at nd-0.007 mg/kg, followed by DDT, endrin, and aldrin. Meanwhile, in the sediments, no organochlorine compounds were detected from all observed sites. Pyrethroid compounds were detected in bilih fish at six sites. The compound with the highest concentration was permethrin (nd-0.02 mg/kg), followed by cypermethrin and α-cypermethrin. The surface sediment from three sites contained two pyrethroid residues, permethrin and α-cypermethrin, at nd-0.002 and nd-0.001 mg/kg, respectively. Our findings show that the residual levels of organochlorine and pyrethroid in bilih fish still meet the standards set by the Codex Alimentarius Commission (CAC). Nevertheless, Bilih fish accumulate more pesticide than surface sediment, so it is essential to be aware of their potential accumulation in the human body as the final consumer. Restriction on synthetic pesticide application is necessary to reduce its residue input into the lake waters for ecological and human health.

Abstract

Air minum adalah air yang melalui proses pengolahan atau tanpa proses pengolahan yang memenuhi syarat kesehatan dan dapat langsung diminum. Saat ini mikroplastik telah mencemari berbagai makanan dan minuman termasuk air minum dalam kemasan. Mikroplastik merupakan partikel plastik yang berukuran kurang dari 5 mm. Berdasarkan penelitian yang telah dilakukan pada AMDK asal Indonesia ditemukan mikroplastik pada AMDK yang tidak terpapar matahari. Penelitian ini bertujuan untuk menghitung kelimpahan dan menganalisis jenis mikroplastik pada Air Minum Dalam Kemasan di Kota Padang. Selain itu juga dilakukan Uji Kruskal Wallis untuk mengetahui perbedaan konsentrasi mikroplastik terhadap merek Air Minum Dalam Kemasan yang berbeda di Kota Padang. Sampel yang digunakan pada penelitian ini berjumlah 30 AMDK 600 ml yang berasal dari 3 merek berbeda. Analisis mikroplastik dilakukan melalui 2 tahapan, yaitu penyaringan dengan bantuan vacuum filter dan pengamatan menggunakan mikroskop. Hasil penelitian menunjukkan bahwa semua sampel AMDK telah terkontaminasi mikroplastik. Kelimpahan rata – rata mikroplastik yang ditemukan pada sampel AMDK terdapat pada rentang 5–11 partikel/L. Partikel mikroplastik yang ditemukan didominasi oleh partikel fragmen, lalu diikuti oleh fiber dan pellet. Berdasarkan hasil dari Uji Kruskal Wallis yang telah dilakukan didapatkan nilai output Asymp.Sig adalah sebesar 0,002 yang berarti ada perbedaan signifikan antara kelimpahan mikroplastik ketiga merek AMDK.  Drinking water is defined as water that meets the necessary health requirements for human consumption. It has been found that microplastics, which are plastic particles smaller than 5mm, have contaminated various foods and beverages, including bottled drinking water. Research conducted on bottled water from Indonesia has shown that microplastics were present in bottled water that had not been exposed to sunlight. This study aimed to determine the abundance and types of microplastics present in bottled drinking water in Padang City. Additionally, we conducted the Kruskal Wallis Test to identify any differences in microplastic concentrations among the different brands of bottled drinking water in Padang City. Our sample consisted of 30 bottles of 600 ml from three distinct brands. Microplastic analysis was conducted in two stages: filtering with a vacuum filter and observation under a microscope. The results indicate that the bottled water samples were contaminated with microplastics, with an average abundance of 5-11 particles/L.  Fragment particles were the most dominant type of microplastic found, followed by fibers and pellets, according to the results of the Kruskal-Wallis Test, the Asymp.Sig output value is 0.002, indicating a significant difference in microplastic abundance among the three bottled water brands.

Abstract

Salah satu sumber terbesar dari pencemaran udara berasal dari gas buang kendaraan. Salah satu jenis pencemaraan udara adalah particulate matter (PM), yaitu PM10 dan PM2,5. Jalan Gajah Mada, khususnya MAN 2 Kota Padang, setiap harinya dipenuhi oleh kendaraan. Tujuan penelitian adalah menganalisis hubungan jumlah kendaraan dan temperatur udara terhadap konsentrasi PM10 dan PM2,5. Pengukuran PM10 dan PM2,5 menggunakan Multifunction Air Detector Digital. Pengukuran jumlah kendaraan secara manual menggunakan counter. Pengukuran temperatur udara menggunakan anemometer. Hasil penelitian menunjukkan rata-rata harian jumlah kendaraan, temperatur udara, konsentrasi PM10 dan konsentrasi PM2,5 yang didapat di depan MAN 2 Jalan Gunung Pangilun yaitu 625,76 unit, 28,88ºC, 39,37 µg/m3, dan 35,49 µg/m3. Jumlah kendaraan bermotor dengan konsentrasi PM10 dan PM2,5 di udara ambien depan MAN 2 Jalan Gajah Mada memiliki hubungan sedang. Sedangkan kecepatan kendaraan di Jalan Gajah Mada tidak memiliki hubungan atau tidak mempengaruhi konsentrasi PM10 dan PM2,5. Kecepatan kendaraan tidak selalu berpengaruh terhadap konsentrasi PM10 dan PM2,5 dikarenakan konsentrasi PM10 dan PM2,5 terdispersi di udara yang disebabkan oleh faktor lain seperti kecepatan dan arah angin. Variabel temperatur udara dengan konsentrasi PM10 dan PM2,5 di udara ambien Jalan Gajah Mada tidak memiliki hubungan karena alat penelitian tidak ter kalibrasi sehingga data tidak dapat digunakan untuk uji lebih lanjut. Sedangkan menurut jurnal dan penelitian sebelumnya, variabel temperatur udara memiliki hubungan dengan konsentrasi PM10 dan PM2,5.

Abstract

This study, titled “Modification of Power Sprayer into a Pest Spraying Tool for Citrus Plants (Citrus Sp),” was conducted in Gunuang Omeh Sub-district, Lima Puluh Kota Regency, from September to October 2024. The objective was to assess the efficiency of a power sprayer and the effectiveness of pest control on citrus plants. The research involved modifying the nozzle of the power sprayer and conducting field tests on a 20 x 20 meter plot. Observations included flow rate, insecticide output capacity, spray distribution, operator walking speed, theoretical field capacity, effective field capacity, spraying efficiency, wind speed, and operator power. In addition, the performance of the power sprayer was compared with that of a knapsack sprayer. Based on the results, the average flow rate was 0.008874 L/s; average droplet size from the power sprayer was 0.3611 mm; average operator walking speed was 0.0413 m/s; average theoretical field capacity was 0.076764 ha/h; average effective field capacity was 0.058789 ha/h; average wind speed was 1.22 km/h; and average operator power was 0.227 kW. The average spraying efficiency of the power sprayer and knapsack sprayer was 76.66% and 60.66%, respectively. These findings indicate that the power sprayer is more efficient than the knapsack sprayer, as it requires less time, less physical effort, and delivers a comparable spray output. Furthermore, the power required by the operator when using the power sprayer is lower than that of the knapsack sprayer.

Abstract, Urban Forest is one of the Public Green Open Space which is controlling atmosfer, water, and soil pollution. Carbon dioxide (CO2) is one of the emission substances of greenhouse gas sources. Increased concentration of CO2, which comes from burning fuel oil and gas, can cause various diseases, such as upper respiratory tract infections, heart disease, cancer and etc. Therefore, it is necessary to reduce CO2 emissions, which one of them is through the utilization of Public Green Open Space, especially urban forest. Jambi City as the most populous area in Jambi Province has high CO2 emission potential. The purpose of this research is to predict the potential of tree vegetation in urban forest in Jambi City in reducing CO2 gas. The research was conducted in 3 locations: Bagan Pete Urban Forest, Muhammad Sabki Urban Forest, and Pine Forest Kenali. The vegetation analysis was performed using the Quadrant Method, where the 10 x 10 m observation plot was determined randomly. Vegetation analysis at each location was conducted to obtain basal area, which then determined the potential of CO2 emission reduction. The basal area of the trees vegetation at each location was 72,72 m2/Ha, 25,45 m2/Ha and 5,12 m2/Ha. Reduction of CO2 of tree vegetation in urban forest in each location in sequence was 41386 Ton/Ha/Year, 14482.93 Ton/Ha/Year, 2916.94 Tons/Ha/Year. Bagan Pete Urban Forest has the highest reduction potential. Based on this research, total carbon dioxide emission reduction potential through urban forest in Jambi City was 58785,87 Ton/Ha/Year.

Abstract

The Indonesian tofu industry is dominated by small scale industries with limited capital, so most do not have waste treatment facilities. Waste from the tofu industry in the form of liquid waste has a high BOD and COD content, and exceeds the quality standards set by PerMenLHK No. P.21 of 2018. Treatment of liquid waste from the tofu industry is necessary to reduce BOD and COD concentrations. Phytoremediation is an effective, efficient and environmentally friendly liquid waste treatment method to reduce BOD and COD parameters. This research aimed to determine the effectiveness of Azolla microphylla and Eichhornia crassipes in reducing BOD and COD of tofu liquid waste. The research data consists of BOD and COD test results following the phytoremediation method with a contact time of 15 days. Initial testing of tofu liquid waste showed BOD and COD results of 193.5 mg/L and 489.2 mg/L, respectively. After the tofu liquid waste was treated with the phytoremediation method, the BOD and COD reduction efficiencies were 48.27% and 74.52%, respectively. The effective weight combination for the reduction of BOD and COD parameters is 100 Azolla microphylla + 300 Eichhornia crassipes.
