Abstract

Sulfonated polyether ether ketone (SPEEK) was utilized as a proton exchange membrane (PEM) in Microbial Fuel Cell (MFC). The SPEEK performance in producing electricity had been observed in MFC using wastewater and glucose as substrates. The MFC with catering and tofu wastewater produced maximum power density about 0.31 mW/m2 and 0.03 mW/m2, respectively, lower that of MFC with tapioca average power density of 39.4 W/m2 over 48 h. The power density boosted because of the presence of Saccharomyces cerevisiae as inoculum. The study using of S. cerevisiae and Acetobacter acetii, separately, were also conducted in with glucose as substrate. The MFC produced an average power densities were 7.3 and 6.4 mW/m2 for S. cerevisiae and A. acetii, respectively. The results of this study indicated that SPEEK membrane has the potential usage in MFCs and can substitute the commercial membrane, Nafion.Article History: Received: Juni 14th 2017; Received: Sept 25th 2017; Accepted: December 16th 2017; Available onlineHow to Cite This Article: Putra, H.E., Permana, D and Djaenudin, D.

Abstract

Tujuan Penelitian ini adalah  untuk menganalisis faktor-faktor kohesi dalam tim olahraga yaitu dengan mengukur dua aspek perbandingan (sosial item, task item atau tugas individual) dalam olahraga dan mengetahui perbedaan tingkat partisipasi olahraga antara siswa yang berada di wilayah perkotaan dengan pedesaan. Metode penelitian yang dilakukan menggunakan pendekatan deskriptif kuantitatif dengan studi analitik cross sectional. Populasi yang digunakan sebanyak 80 siswa usia (9-12 tahun) dengan keahlian olahraga dibidang tertentu dan bertempat tinggal di wilayah kota maupun desa. Hasil menunjukkan bahwa (1) hasil rata-rata keseluruhan siswa kota dengan desa sebesar 82,7% di indikator sangat baik; (2) hasil rata-rata siswa kota sebesar 82,64% dan rata-rata siswa desa sebesar 80,06%. Hal ini menunjukkan bahwa tidak ada perbedaan yang signifikan antara siswa kota dengan desa, keduanya berada pada indikator sangat baik.

Abstract

Transaction reporting and financial management systems play a vital role in ensuring the efficiency and sustainability of businesses, both small and large. The development of technology has brought major changes to corporate procedures, including the transformation of MSMEs from manual paper-based records to a more modern digital system. One innovative solution is the use of digital wallet applications such as OVO, which is popular in Indonesia. OVO allows its users to conduct various financial transactions online, including cashless payments, money transfers and bill payments. In this context, payment is the process of transferring value from a consumer to another party, whether for the purchase of goods or services, payment of bills, or transfer of funds. With OVO, the payment process becomes faster, more practical and secure, helping MSMEs adapt to modern technology and improve their operational efficiency. In addition, the app also makes it easier for consumers to keep up with the trend of digital transactions, creating comfort and convenience in their daily lives and business activities. The adoption of payment technology like this supports the digital transformation of MSMEs and encourages more inclusive economic growth.

Abstract

Dirty water can endanger the health and mental safety of humans, which can lead to outbreaks of cholera, ringworm, scabies, diarrhea/dysentery, and typhoid which are some of the diseases that arise from dirty water which are still consumed without further processing. To deal with dirty water, researchers have a solution with a water filtering system using a water purification system with an Arduino- based Pid sensor control, where the water will be filtered in the water treatment then the water will be detected by the LDR sensor is still cloudy or clean, if the water is still cloudy, Arduino will send the command to relay to turn on the water pump so that the water will flow back to the water treatment. if the water is clean, the water will be put into the container that has been provided. Then the results from the water will be displayed in the application that was made using the Inventor app. Verify the results of system testing that the application is running very well when displaying the results of the system being created.
