    The study aims to observe the effect of storage time on the hydrolytic rancidity of fish meal as source of protein in animal feed. This study used a completely randomized design with four treatments and four replications. The arrangement of the fish meal storage time treatments were T0: 0 weeks, T1: 2 weeks, T2: 4 weeks and T3: 6 weeks. Temperature and humidity were measured during storage in warehouse. Parameters measured were moisture and free fatty acid. The results showed that fish meal which has been stored at different times was significantly affecting (P<0.05) on moisture and free fatty acids. The average of temperature and humidity during storage (0 - 6 weeks) were 29-30oC and 60-76%. The highest moisture was 17.38% obtained in the T3 and the highest free fatty acid content was obtained at 4.30%

    Pada penelitian ini dikembangkan suatu sistem pemantau kesehatan pasien menggunakan sensor nirkabel yang memungkinkan alat ukur dan alat pemantau kesehatan pasien ditempatkan pada ruangan yang berbeda. Alat ukur dapat ditempatkan di kamar pasien sedangkan alat pemantau dapat ditempatkan di ruangan tenaga medis sehingga tenaga medis khususnya dokter atau petugas jaga dapat memantau kondisi kesehatan pasien secara terus menerus dari ruangan petugas jaga. Protipe alat ukur dan pemantau kesehatan yang dikembangkan memanfaatkan pulse sensor untuk mengukur kondisi denyut nadi pasien, microcontroller arduino untuk proses kendali pengiriman data dan teknologi nirkabel XBee untuk pengiriman data dari alat ukur (sensor) ke alat pemantau (komputer). Hasil penelitian menunjukkan bahwa prototipe alat ukur yang dikembangkan dapat menghitung denyut nadi pasien dengan tingkat perbedaan sebesar 0.007% dengan hasil perhitungan dokter menggunakan stetoskop yang dipasang di dada pasien

    Performance Evaluation of ZigBee-based Wireless Sensor Network for Monitoring Patients??? Pulse Status

    Recently, the wireless sensor network has been widely deployed for medical care purpose. We have developed a wireless sensor network that can monitor the patients??? pulse status for triage purpose, so that a medical team can monitor remotely the health condition of patient and they can treat the patient based on severity of patients??? health condition. We developed an electronic triage operating as a sensor node (SN) tagged in patient???s arm. The SN consists of microcontroller ATmega328P, ZigBee and pulse sensor to detect patient???s pulse. Operating as an electronic triage, the pulse rate from sensor is classified into three categories of severe condition, i.e. major, minor and normal status by the microcontroller in SN and sent to the coordinator node (CN) through ZigBee interface. Our system can be deployed in emergency room, triage room, pre/post-op surgery in hospital as well as in disaster area. This paper aims to evaluate the performance of the ZigBee-based wireless sensor network that we developed. We evaluate the effective distance between CN and SN to deliver patients??? pulse rate via ZigBee as well as the effective number of SNs that can be accommodated by single CN. The experimental results shown that the effective distance between CN and SN to deliver the pulse rate data is less than 30 meters and the maximum number of SNs can be accommodated by a single CN is 3 (three) nodes
