Abstract

Desalinasi merupakan metode untuk mengubah air laut menjadi air tawar. Salah satu metode yang yang ramah lingkungan dan hemat energi adalah menggunakan elektroda karbon dengan prinsip kapasitif. elektroda karbon yang telah difabrikasi menggunakan bahan campuran antara karbon aktif dan PVA dengan komposisi perbandingan 20:1. Hasil campuran bahan – bahan dicetak diatas graphite sheet dengan ukuran 80 x 60 x 0,5 mm3. Proses desalinasi berlangsung sebanyak 2 siklus adsorbs dan desorbsi. Siklus adsorbsi adalah siklus saat elektroda dialiri tegangan listrik sehingga ion – ion akan tertarik ke elektroda dan air menjadi berkurang kadar garamnya. Sedangkan siklus desorbsi adalah siklus ketika tegangan elektroda dilepas dan ion – ion yang menempel saat siklus adsorbsi akan lepas kembali. Hasil pengukuran TDS yang digunakan untuk mewakili pengukuran kadar garam air sampel menunjukkan penurunan nilai TDS sebesar 32,5% dari kondisi awal. Pengukuran temperatur air sampel selama proses desalinasi menunjukkan tidak terjadi perubahan.

Abstract

Sumber air bersih yang berasal dari sungai sudah tercemar dan tidak bisa digunakan untuk kebutuhan sehari - hari. Salah satu penyebab pencemaran air sungai adalah limbah kamar mandi. Sifat air limbah kamar mandi yang basa dan mengandung banyak deterjen mengakibatkan air tersebut susah diurai oleh mikroorganisme yang ada dalam air, agar air limbah tersebut dapat digunakan, maka perlu adanya proses daur ulang. Penelitian dilakukan menggunakan teknologi plasma untuk mengolah air limbah. Plasma dibangkitkan dengan menggunakan memodifikasi transformator flyback berfrekuensi 7 KHz, 8 KHz dan 10 KHz. Tegangan yang dihasilkan berupa tegangan tinggi (High Voltage) antara 5 ? 24 KV. Variabel yang diteliti dari air limbah kamar mandi adalah pH dan TDS (Total Dissolve Solid). Proses daur ulang dimulai dengan dipaparkannya plasma pada permukaan air selama 20 menit dan dijaga pada suhu konstan. Hasil penelitian menunjukkan terjadi penurunan pH air dari 10,0 menjadi 8,1 dengan menggunakan teknologi plasma (electron discharge). Sedangkan untuk pengukuran TDS mengalami kenaikan dari nilai 135 ppm menjadi 210 ppm.

Abstract

Lokasi SMA Negeri 1 Tumpang di Desa Malangsuko, Kabupaten Malang berpotensi terjadi bencana alam, seperti halnya beberapa wilayah lain di Kabupaten Malang, salah satunya adalah gempa bumi. Namun demikian, pendidikan mitigasi bencana yang melibatkan aktivitas partisipatif dari siswa-siswi di sekolah tersebut belum pernah dilakukan. Kegiatan school watching dilaksanakan sebagai upaya meningkatkan kesadaran terhadap potensi bahaya di lingkungan sekitar bagi siswa-siswi di SMA Negeri 1 Tumpang. School watching merupakan kegiatan pemetaan potensi bahaya yang ada di sekitar sekolah. Hasil pemetaan tersebut selanjutnya disajikan dalam bentuk peta dan dipresentasikan oleh peserta. Sebanyak 50 siswa-siswi SMA Negeri 1 Tumpang dilibatkan dalam kegiatan ini yang dibagi menjadi 5 kelompok. Masing-masing kelompok didampingi oleh satu orang dari tim Pengabdian kepada Masyarakat (PkM). Kegiatan ini berhasil meningkatkan kepekaan peserta terhadap potensi bahaya yang ada di sekitarnya. Hal ini terlihat dari presentasi potensi bahaya yang ada di sekolah dan upaya mitigasinya. Lebih lanjut, hasil pengisian kuisioner menunjukkan lebih dari 90% peserta menyatakan kegiatan tersebut penting untuk meningkatkan kepekaan terhadap potensi bahaya di sekitarnya. Oleh karenanya, kegiatan school watching perlu dilakukan secara rutin dengan melibatkan semua siswa-siswi dan guru di SMA Negeri 1 Tumpang dan sekolah-sekolah lain sebagai upaya menciptakan warga sekolah yang tanggap bencana.

Abstract

Clean water sources from rivers are polluted and cannot be used for daily needs. One of the causes of river water pollution is bathroom waste. The nature of bathroom waste water which is alkaline and contains a lot of detergent causes the water to be hard to decompose by microorganisms present in the water. so that the wastewater can be used, it is necessary to have a recycling process. The study was conducted using plasma technology to treat wastewater. Plasma is generated by modifying flyback transformers with a frequency 7 kHz, 8 KHz and 10 KHz. The resulting voltage is in the form of high voltage (High Voltage) between 5-24 KV. The variabels studied from bathroom wastewater were pH and TDS. The recycling process begins with the exposure of plasma to the water surface for 20 minutes and maintained at a constant temperature. The results showed a decrease in water pH from 10.0 to 8.1 using plasma (electron discharge) technology. As for the measurement of TDS, it has increased from 135 ppm to 210 ppm.

Abstract

Desalination is a method for converting sea air into fresh air. One of the eco-friendly and energy saving method is to use carbon electrodes with capacitive principles. A fabricated carbon electrode using a mixture of activated carbon and PVA uses ratio composition 20:1. The mixture of the material is printed on a graphite sheet 80 x 60 x 0.5 mm3. The desalination process takes 2 cycles of adsorption and desorption. The adsorption cycle is a cycle when electrode is fed. The ions will be attracted to the electrode and the salt in the air will be reduced. While desorption cycle is the cycle when the electrode voltage is detached and the ions adhered on adsorption cycle will be detached. The result of TDS which is used as the sample water salt measurement shows that the reduction of TDS value is 32,5% from the formerly condition. The temperature measurement of water sample during desalination process shows that the temperature does not have any changing.

Abstract

Benzo[a]pyrene is one of the compounds from the Polycyclic Aromatic Hydrocarbons (PAHs) group that is found in various places as a by-product of combustion. In addition, this compound also has carcinogenic properties so it has a bad impact on human health. Therefore, research is needed to detect the presence of benzo[a]pyrene compounds by designing a measurement system for this detection, especially in burning tobacco. The measurement system that has been designed uses a RobotDyn Mega WiFi 2560 microcontroller and an MQ-6 gas sensor that has been calibrated with benzo[a]pyrene compounds. The results showed that the concentration of benzo[a]pyrene detected when burning tobacco at a mass of 0.33 gram was 4.86 ppb, 7.38 ppb for 0.436 grams mass burning, and was 8.81 ppb for burning at a mass of 0.52 grams. Therefore, this measurement system has been able to detect benzo[a]pyrene compounds

Abstract

Background: Farmers can market their crops due to the significant market share for hydroponic agriculture products. However, this presents a dilemma as the market demands a consistent supply of high-quality crops. Precise nutrient levels and controlled chemical-physics parameters are crucial considerations in hydroponic yields. Thus far, these factors have been managed manually, leading to challenges in achieving desired outcomes. Objective: This community service program aimed to address this issue by developing a real-time automated system for monitoring and controlling chemicalphysics parameters and nutrient levels via an Android application. The goal was to enhance the effectiveness and productivity of hydroponic crop harvests. Method: The program commenced with designing the system based on farmer requirements, followed by the installation and testing of equipment at partner locations. Subsequently, technical training on system features and usage was provided. Results: The system was successfully installed at Grahaponik. According to questionnaire responses, 68.4% of farmers expressed satisfaction, and 78.9% of total participants reported that the system was easy to employ. Technology installation, implementation, and dissemination to local hydroponic farmer groups were conducted. Hydroponic farmers acknowledged the user-friendliness of the devices. Conclusion: Partners' acceptance of the instruments was favorable, facilitating their ease of use and thereby enhancing the effectiveness of hydroponic farming.
