Abstract

COD level of Pojok Laundry’s wastewater did not meet the quality standard regulated in the Special Region of Yogyakarta Regulation No. 7 of 2016 (>150 mg/l) which was 442.5mg/l. This study was aimed to decrease COD levels using the tray aerator method. Manganese greensand with a diameter of 0.25 mm and a thickness of 2.4 cm/tray was also added. This type of research was a quasi-experimental with Nonequivalent Control Group Design. The sample in this study amounted to 50 samples with 5 treatments (30, 45, 60, 75, and 90 minutes), and 5 repetitions. Samples were taken from the washing machine outlet pipe. There were two groups, where the control group was only given aeration and the treatment group was given aeration with the addition of manganese greensand. Data analysis using the two-way ANOVA test showed that there was an effect of time variations on the decrease in COD levels (p<0.05), there was a difference in the average of decreased levels of COD between the control and treatment groups (p<0.05). The average decrease in COD levels after treatment with a time of 30, 45, 60, 75, and 90 minutes, respectively, was 195.7 mg/l (28.80%); 299.0 mg/l (43.63%); 372.1 mg/l (54.79%); 438.3 mg/l (64.61%); and 513.8 mg/l (75.45%). The decrease in COD levels increased with time. The conclusion of this research was that tray aerator with manganese greensand addition can reduce COD levels with the highest reduction up to 76.69% (90 minutes treatment, detergent usage: 30 g).

Abstract

Aktivitas sehari-hari manusia menghasilkan produk samping berupa sampah. Sampah merupakan limbah hasil yang bersifat padat terdiri dari zat organik dan zat non organik yang dianggap tidak berguna lagi dan harus dikelola agar tidak membahayakan lingkungan. Timbulan sampah yang dihasilkan tiap tahunnya semakin bertambah. Total sampah nasional pada tahun 2021 mencapai 68,5 juta ton dengan proporsi sampah tidak terkelola sebanyak 10,695,895.16 (ton/tahun) Untuk mengurangi beban tersebut diperlukan pengelolaan yang dapat mengurangi jumlah sampah yang harus dibuang ke tempat pembuangan akhir (TPA). Pengelolaan sampah tingkat rumah tangga dengan komposting merupakan salah satu alternatif untuk mngurangi jumlah sampah. Tujuan kegiatan pengabdian ini adalah untuk meningkatkan kualitas perilaku masyarakat Kelurahan Jabungan dalam Pengelolaan Sampah dengan memberikan pengetahuan, merubah sikap dan praktek masyarakat dalam pengelolaan sampah melalui alternatif penanganan sampah yaitu memanfaatkan kembali sampah yang bisa digunakan dengan Bank Sampah dan memanfaatkan kembali sisa sampah organik menjadi pupuk cair. Peserta kegiatan pengabdian ini adalah perwakilan RW, PKK, LPMK, dan Karang Taruna kelurahan Jabungan Kecamatan Banyumanik Kota Semarang. Bentuk kegiatan yang dilakukan berupa ceramah, diskusi tanya-jawab, dan demonstrasi. Hasil kegiatan pengabdian menunjukkan bahwa peserta sangat aktif dan antusias dalam mengikuti pemberdayaan yang dibuktikan dengan banyaknya peserta yang bertanya serta menyampaikan pendapatnya saat sesi diskusi dan tanya jawab. Dari kegiatan pemberdayaan ini dapat disimpulkan bahwa peserta telah memahami pengelolaan sampah, perintisan bank sampah, serta mengubah sampah organik rumah tangga menjadi kompos cair.Kata kunci: Bank sampah, sampah organik, komposting, pengabdian masyarakat

Abstract

Introduction: Pulmonary tuberculosis is ranked the second health problem in the world, including Indonesia with reasonably high mortality rates. This study examined the association between the ventilation, physical condition, and the prevalence of pulmonary tuberculosis in the working area of the Sragen Primary Healthcare Center. Methods: This study used a case-control design and purposive sampling to select 40 patients with positive smear pulmonary tuberculosis as the case group and 40 subjects with negative smear pulmonary tuberculosis as the control group who lived in the same area. Results and Discussion: Ventilation volume per hour (p = 0.007; OR = 3.889; 95% CI = 1.533–9.868), ventilation area (p = 0.014; OR = 3.462; 95% CI = 1.379–8.691), lighting intensity (p = 0.007; OR = 3.955; 95% CI = 1.546–10.114) and a humidity level (p = 0.001; OR = 5.762; 95% CI = 2.065–16.079) were associated with the prevalence of pulmonary tuberculosis in patients of the productive age group who attended the Sragen Primary Healthcare Center. The results of the multivariate analysis conclude that ventilation (OR = 5.900), humidity level (OR = 8.414), and occupancy density (OR = 0.113) had joint influences with a significant contribution of 41.3% to TB prevalence. Conclusion: House' ventilation and humidity are the main factors contributing to the incidence of pulmonary tuberculosis in the working area of Sragen Primary Healthcare Center.

Abstract

The brick industry has the potential to create a source of pollution in the form of dust which is harmful to the environment and workers health from the burning process. This study aims to determine the risk factors and analyze the relationship between dust exposure and symptoms of respiratory disorder in workers. This study used the total sampling technique to choose a sample of 75 participants for an observational study with a cross-sectional approach. The results showed that the average total dust particulate levels at 13 points was 1748.47 µg/Nm3 and the average inhaled dust content in 75 respondents of 4.56 mg/m3. The results of the analysis showed that the variables associated with symptoms of respiratory disorder were inhaled dust levels (p=0.023), working period (p=0.040), length of exposure (p=0.032), and use of personal protective equipment (p=0.015). Workers in the brick sector in Tegowanuh Sub-District may have respiratory symptoms more frequently depending on their exposure to amounts of inhaled dust, working period, exposure duration, and use of personal protective equipment. During the work process, it is advised to use personal protective equipment as a mask to prevent the onset of respiratory problems.

Bermain dalam pembelajaran tidak hanya disukai oleh anak-anak, tetapi sangat bermanfaat bagi perkembangan anak, yang meliputi manfaat motorik, manfaat afeksi, manfaat kognitif, manfaat spiritual, dan manfaat keseimbangan. Tujuan uji validitas dan reliabilitas mengetahui perbedaan pengetahuan, sikap, praktik dan perilaku pengendalian vektor untuk pencegahan filariasis sebelum dan sesudah diberikan intervensi. Intervensi diberikan pada siswa kelas 5 di SDN 1  X di Kota Pekalongan jumlah 30 siswa. Uji bivariat mengunakan uji t Independent dan uji wilcoxon. sebagian besar variabel penilaian menunjukkan nilai p-value 0,05, pada nilai α 0,05, artinya terdapat perbedaan signifikan antara pretest dengan posttest. Hanya variabel perilaku tidur siang yang tidak memiliki perbedaan signifikan (p-value 0,073). Hasil evaluasi media permainan menunjukkan rentang rata-rata nilai antara 90,70 sampai dengan 95,00 dengan rata-rata nilai rata-rata terendah adalah untuk desain buku selamat datang sebesar 90,70 dan standard deviasi 11,50.

Abstract

Tubercolusis is a disease that attacks the lungs. The disease is caused by the bacterium mycobacterium tubercolusis. The bacteria mycobacterium tubercolusis can be killed by antibiotics. However, continuous use of antibiotics can cause bacterial resistance. So we need to find new drugs that can prevent multi-drug resistant tuberculosis. This study aims to determine the antibacterial activity of MDR TB from soft coral symbiont bacteria Lobophytum sp. There were 6 bacterial isolates obtained from soft coral Lobophytum sp. One isolate from Lobophytum-associated bacteria were successfully screened for antimycobacterial against MDR TB bacteria. PLO2 was found to inhibit the growth of MDR TB (MDR TB strain SIRE and R). Based on the results of identification with PCR, soft coral symbionts of PLO2 was closely related to Virgibacillus marismortui with homology of 99%.
