Abstract

The simulation design of this animal waste treatment plant is a design that applies the sewage treatment plant system which is made to cope with environmental pollution, especially rivers due to indiscriminate disposal of animal waste. Making this animal waste treatment plant provides information to readers or the public about how to design an animal waste treatment plant system and the performance of the sewage treatment system so that people know how to deal with environmental pollution caused by the livestock themselves. The manufacture of this installation system uses data collection methods from direct farmers and theories obtained from books, journals, and articles related to sewage treatment plant theory, plumbing, electricity, and others. Finally, the data was collected by testing the animal dung waste treatment system where the test data was taken from the pH content of the water used for processing the animal dung waste treatment system. The test results on the sewage treatment plant system concluded that in order to obtain optimal results or water pH content, namely the pH content of 6, it is necessary to deposit animal manure between two to three days, while the maximum processing of this system is the pH content of 6.5. and processing of animal manure, which is on the fourth day to get the maximum pH content.

Abstract

Manual conveyance is the work of transporting material carried out by workers to move material from an origin location to a destination location. The purpose of the study was to overcome the complaints experienced by housewives in the process of transporting 12kg LPG. The research was conducted using a two-period cross over design method. Musculoskeletal complaints experienced by housewives on the back, waist, knees and calves. Musculoskeletal complaints were measured using a Nordic Body Map questionnaire with a Likert scale, the data obtained were tested with independent t-test and t-pair. The results of the analysis showed that the use of 12 kg LPG conveyance could reduce musculoskeletal complaints from an average of 80.1 to 70 or decreased by 12.6%. It was concluded that the use of 12 kg LPG conveyance could reduce musculoskeletal complaints in housewives. It is recommended for those over 30 years of age to lift and carry heavy loads to use assistive devices.

Abstract

Penelitian ini membahas perancangan dan evaluasi kinerja jaringan sensor nirkabel (Wireless Sensor Network/WSN) berbasis ZigBee IEEE 802.15.4 untuk monitoring lingkungan data center. Sistem terdiri atas node sensor yang melakukan akuisisi parameter lingkungan dan node koordinator sebagai penerima data. Evaluasi kinerja dilakukan melalui pengujian Received Signal Strength Indicator (RSSI), delay, packet loss, dan perubahan tegangan baterai terhadap variasi jarak komunikasi. Pengujian dilakukan pada lingkungan outdoor sebagai karakterisasi awal kinerja komunikasi sistem. Uji jangkauan menggunakan perangkat lunak X-CTU menunjukkan bahwa komunikasi ZigBee masih dapat terdeteksi hingga jarak 19 m, sedangkan evaluasi QoS dilakukan pada jarak 1–12 m dan komunikasi terputus pada pengujian 13 m. Hasil pengujian menunjukkan bahwa peningkatan jarak komunikasi diikuti oleh penurunan kualitas transmisi, yang ditunjukkan oleh peningkatan delay hingga 6,6 detik dan packet loss sebanyak 55 dari 126 paket yang dikirim pada jarak 12 m. Pengamatan kondisi sumber daya selama interval pengujian 10 menit menunjukkan penurunan tegangan baterai sebesar 0,32–0,68 V pada variasi jarak yang diuji. Perubahan tegangan baterai tidak menunjukkan kecenderungan linier terhadap pertambahan jarak komunikasi sehingga digunakan sebagai indikator perubahan kondisi sumber daya selama pengujian dan tidak merepresentasikan konsumsi daya secara langsung. Hasil penelitian menunjukkan bahwa jarak komunikasi berpengaruh terhadap kinerja jaringan ZigBee, terutama pada delay dan packet loss. Sistem yang dikembangkan menunjukkan potensi penggunaan ZigBee sebagai media komunikasi WSN untuk monitoring lingkungan data center, dengan penempatan node dan jarak komunikasi sebagai faktor penting dalam implementasinya.
