To maintain school order, it is necessary to give punishment as stipulated in the school\u27s decision. Decision Support System can be implemented as a media to support decision making in giving punishment to problematic students. In general, punishment for problematic students uses a point system according to the type of violation. However, the calculation and management process is still done conventionally which is prone to human error. Engineering punishment is very likely to occur due to the like and dislike factor. This of course causes the school\u27s decision to be wrong. This study aims to make a Decision Support System application to determine the level of punishment for problematic students using the Simple Additive Weighting (SAW) method and the Decision Table. The weighting of violation points is based on three criteria, namely academic violations, aesthetic violations, and ethical violations. The results showed that the calculation of the weighted score of each type of student violation became more precise
Modifikasi Bak Pendingin Pada Proses Produksi Asap Cair Tempurung Kelapa Untuk Peningkatan Volume Produksi
Get PDFIncreasing the production of liquid smoke is an attempt to raise the utilization of coconut shells as a by-product of the coconut fruit. The distillation process is a way to produce liquid smoke and condensation occured in the cooling bath. Improving the cooling bath can increase the production volume. This study aims to determine the performance of the cooling bath in 10 experiments with variations in the level of the water flow rate factor of 20 liters/minute, 25 liters/minute, 30 liters/minute, and the level of the airflow velocity factor of 35 m/s, 40 m/s. and 45 m/s. Modifying the cooling bath can improve its performance and increase the volume of liquid smoke. The largest increase of 36.14% was achieved at the water flow rate in the level of 30 liters/minute and the airflow velocity factor in the level of 45 m/s, at 26.2oC of the cooling bath temperature
Perancangan Mesin Cetak Biopellet Sekam Padi Dengan Menggunakan Software Solidwork 2016
Get PDFIndonesia\u27s consumption of energy increases significantly each year. While the reserves of energy are declining every year, alternative energy is needed. The waste treatment of rice husk biomass has been used for alternative energy, so the research aims to optimize the waste into fuel. The research site was conducted in Kelapa Dua Village, Jaya Subdistrict, Karawang Regency. To get the results of the design, there needs to be technological engineering to design production machines with the help of solidworks 2016 software. The research resulted in the form of compounding tools, as follow: Screw press diameter (Ds = 200 mm), screw height (hs = 65 mm), screw shaft diameter (dps = 70 mm), screw lift length (L = 420 mm), nominal screw diameter (Dn = 177.8 mm), screw lift width (Fd Max = 14 mm), screw spacing (pitch) (P = 60 mm), screw number (n = 7 threads), helix angle (β = 8), screw press power requirement (Pe = 119.27 watts), torque (T = 326.1 N.m), screw lift load (Ws = 141.5 N) and pressure developed on screw thread (PS = 1.65 N/mm2)
Pengaruh Penambahan Serat Kulit Kopi dan Polivinil Alkohol (PVA) terhadap Karakteristik Biodegradable Foam dari Pati Kulit Singkong
Get PDFPolystyrene plastic or styrofoam is very popular to be used as a food packaging container even though Styrofoam has a bad impact on health. In addition, Styrofoam also cannot be biodegraded naturally in the environment so the use of syrofoam is also a problem for the environment. One alternative to styrofoam is biodegradable foam (biofoam) made from starch and cellulose. It is safe for health and can be broken down naturally. Cassava peel is rich in starch (carbohydrates) but has low cellulose content. Meanwhile, coffee peel is rich in cellulose and minimal in carbohydrates. Both types of waste have the potential to become biodegradable foam raw materials. The addition of synthetic polyvinyl alcohol (PVA) polymer is expected to improve the mechanical quality of biodegradable foam. This study aims to obtain the best formulation for the manufacture of biodegradable foam from cassava starch with the addition of coffee peel cellulose and PVA. The quality of biofoam evaluated includes tensile strength, water absorption, and biodegradability. The best biofoam characteristics were obtained at the addition of 15% fiber and 15% PVA, resulted in water absorption of 28.87%, the tensile, strength of 2.70 N / mm2, and biodegradability of 93.66% for 30 days
Karakterisasi Proses Gasifikasi Menjadi Listrik Berbahan Baku Sampah Padat Perkotaan Menggunakan Reaktor Tipe Downdraft di Provinsi Nusa Tenggara Barat
Get PDFIndonesia is currently experiencing the problem of Municipal Solid Waste (MSW), energy and environmental crisis. Gasification by electric generator is the solution. This study about the design and characterization of the gasification reactor with MSW feed. This research was conducted by examining the effect of gasification temperature (550, 600, 650, 700, 750, 800, 850oC) and Air Fuel Ratio variations (0,5; 0,51; 0,53; 0,54l; and 0,55). The variabel test of temperature variations is syngas concentration, fuel conversion (FC), cold gas efficiency (CGE), carbon conversion efficiency (CCE), and specific fuel consumption (SCF). The AFR evaluated syngas and SCF. The result showed an increase the syngas levels with the increasing the gasification temperature, except CO2. The FC value increased(71% to 74%) and The CGE increases (77 to 97%). The CCE increases from 69% to 78% (550-650oC) and decreases again to 66% (850oC), and SCF decreased (4.5-0.5 kg/kWh). In the AFR variation, syngas levels increase with increasing AFR, but scf decreased (5.3 to 2), this proves efficient combustion

Implementasi Rapid Application Development dalam Pengembangan Aplikasi Pendaftaran Wisuda
Get PDFGraduation is an inauguration activity for students who have finished studying at a university. Graduation registration at the Cilacap State Polytechnic is still done conventionally, causing problems such as students who are not registered in the toga data collection, students who do not return the toga according to the specified time limit. In addition, the large number of students makes the data collection process take longer. In this case, the authors conducted research that aims to build a website-based graduation registration information system. Making this system requires a research methodology. Among them are data collection methods that include literature studies, observations, and interviews as well as the system development method used, namely Rapid Application Development (RAD). The results of the questionnaire with a total score of 182 show that the system is very good in assisting BAAK in graduation registration services and monitoring the number of graduates, as well as helping students register for graduation and their completeness, and the system can help submit and confirm trouble-free forms.Â
Implementasi Model Waterfall pada Pengembangan Sistem Informasi Monitoring Prestasi Mahasiswa
Get PDFCilacap State Polytechnic (PNC) is a Polytechnic that has several scholarships in it. Bidikmisi is one of the scholarships available at PNC. Bidikmisi scholarship recipients are required to report their achievements every semester to the Biro Administrasi Akademik dan Kemahasiswaan (BAAK) which still often experiences problems, including student delays in collecting achievement reports, BAAK finds it difficult to monitor the progress of student achievement, especially in the non-academic field because all the data is in each student. This research focuses on monitoring related to student achievement. Making this system using the waterfall method because it is systematic. The results of the questionnaire show that this system can assist in the process of managing and monitoring student achievement with a percentage of around 60% stating it is good and can help students to notify the results of their achievements and can be accessed at any time without having to wait for information or visit the BAAK room with a high percentage. obtained from the results of the questionnaire about 70% stated goo
