An unhealthy environment can lead to environmental-based disease transmission. Based on the preliminary survey, many houses still do not meet health requirements, such as having no ceiling, closed sewerage, and no latrine. This study aims to determine the description of residential sanitation, including the components of the house, the components of sanitation facilities, and the occupants' behavior. This research is descriptive with the survey method. The population is all houses in Roworejo Village, as many as 1,244 houses. Data collection is done by visiting people's homes, conducting an assessment using a checklist guide. Interviews were conducted to support the required data. The data that has been collected is scored, processed with a computer program, and presented in tabular form. The results of the study found that the majority of the sanitation components had met the requirements. However, there are still physical components of the house (30%), components of sanitation facilities (34%), and unhealthy behavior of residents (30%). Increasing public knowledge is an action that must be taken in order to change public health behavior.
Air limbah tahu mengandung padatan tersuspensi yang akan mengalami perubahan fisik, kimia,dan biologi sehingga menghasilkan zat beracun serta menjadi media pertumbuhan bakteri. Tujuan penelitian ini untuk memperoleh data kemampuan enceng gondok untuk menurunkan kadar BOD, COD dan TSS air limbah tahu tempe dengan variasi konsentrasi air limbah. Metode penelitian bersifat eksperimen semu, menggunakan pre-test dan post-test untuk objek dan kontrolnya. Hasil penelitian menunjukan; 1)kualitas air limbah kosentrasi 100% parameter BOD,COD,TSS adalah 1800 mg/l, 2912 mg/l, 4050 mg/l, Kosentrasi 75% parameter BOD, COD, TSS adalah 864 mg/l, 1369 mg/l, 1985 mg/l, Konsentrasi 50% parameter BOD, COD, TSSadalah 540 mg/l, 917 mg/l, 810 mg/l, 2) Pengaruh variasi kosentrasi air limbah tahu tempe Konsentrasi 100%, Konsentrasi 75% dan Konsentrasi 50% terhadap BOD, COD dan TSS menggunakan uji Anova berpengaruh signifikan hal ini dapat dilihat dari nilai signifikasi semuanya memiliki nilai ≤0,05 dan rekomendasi penelitian ini adalah dilaksanakan rancang bangun IPAL tahu sebagai aplikasi dengan metoda Fitoremidiasi.
Kemiling adalah sebuah Kecamatan di Kota Bandar Lampung, letaknya berada di daerah perbatasan Kota Bandar Lampung. Kecamatan Kemiling terdiri dari kelurahan Beringin Jaya, Kedaung, Kemiling Permai, Kemiling Raya, Pinang Jaya, Sumber Agung, dan Sumber Rejo. Berdasarkan informasi dari Dinas Lingkungan Hidup Kota Bandar Lampung, bank sampah Dinas Lingkungan Hidup (DLH) sudah ada sejak bulan April 2019 tetapi Bank Sampah Dinas Lingkungan Hidup (DLH) di kelurahan Beringin Jaya, Kecamatan Kemiling, Kota Bandar Lampung belum beroperasi secara maksimal. Permasalahan mitra adalah tidak beroperasionalnya bank sampah yang sudah dibangun fasilitas fisiknya. Hal ini disebabkan belum adanya organisasi yang dibentuk untuk mengelola bank sampah di Kelurahan Beringin Jaya. Tujuan kegiatan ini yaitu membentuk organisasi Bank Sampah Di Kelurahan Beringin Jaya, Kecamatan Kemiling, Kota Bandar Lampung. Metode pelaksanaan terdiri dari kegiatan persiapan, pelaksanaan kegiatan pengabdian kepada masyarakat, sosialisasi/ penyuluhan bank sampah, pembentukan organisasi bank sampah, monitoring kegiatan pengabdian kepada masyarakat, evaluasi kegiatan pengabdian kepada masyarakat. Hasil pengabdian ini berupa kegiatan sosialisasi bank sampah kepada warga melibatkan berbagai pihak seperti Dinas Lingkungan Hidup, RT, Kelurahan, petugas pengangkut sampah di Kelurahan Beringin Jaya, PT. Pegadaian Cabang Bandar Lampung, Tim Pengabmas Politeknik Kesehatan Tanjungkarang dan HMJ Jurusan Kesehatan Lingkungan. Hasil lainnya adalah terbentuknya organisasi bank sampah Kelurahan Beringin Jaya yang sudah dibuat strukturnya berdasarkan Surat Keputusan Kepala Kelurahan Beringin Jaya No: 412/21/V58.VI96/2020. Tindak lanjut dari kegiatan ini adalah pendampingan pengoperasian bank sampah, pendampingan ini merupakan kelanjutan dari kegiatan pembentukan bank sampah. Pendampingan pengoperasian bank sampah akan dilaksanakan oleh tim pengabmas yang telah melaksanakan pembentukan organisasi bank sampah
An alternative method of treating hospital wastewater can use a microfiltration membrane, where the results showed that the disposal of oily wastewater reached 82.5%, BOD 90%, COD 85%, and total Coli up to 70%. In addition, it can remove particles from wastewater from 0.04 to 100 microns in size. The problem with using microfiltration membranes is the rapid occurrence of fouling/saturation on the surface of the microfiltration membrane, causing the wastewater treatment operation time to be short. The length of this treatment causes the problem of less amount of wastewater being treated and another problem, namely faster membrane replacement. This study aims to determine the performance of pretreatment of microfiltration membranes made of alum, silica sand, and activated carbon for parameters pH, BOD, COD, TSS, Ammonia, Fatty Oil, and Total Coliform. The results of the study were as follows: 1) the average quality of hospital wastewater was temperature 28.8°C, pH 7, BOD 79 mg/l, COD 167.05 mg/l, Total Suspended Solid 68 mg/l, Ammonia 4 mg/l, Phosphate 0.745 mg/l, Fatty Oil 1.64 mg/l, Coliform 2.200 MPN/100 ml. 2) Comparison analysis of the most effective materials on the parameters, for BOD Silica Sand 78.24%, COD 56.25% Silica Sand, Total Suspended Solids 83.42% Activated Carbon, Ammonia Silica Sand 56.49%, Phosphate 80.43 % Activated Carbon, Fat Oil is 80.43% Alum, Coliform is Microfiltration Membrane 40.91%.
