Abstract

Quality Control (QC) is one of the most important components in the manufacturing process. The aim is to determine whether a product is feasible to market. One aspect of QC is the size / dimension of the object to be made. If the size is still within the range of tolerance, then it has passed the QC in terms of size, but if not then it includes a failed product. The problem encountered is that it takes a long time to take measurements, especially objects in the third dimension where each part is different as microdrill, zipper etc. To overcome this weakness, a CCD camera is used as a sensor to record images and then use LabVIEW software to analyze the size of the recorded image. This is a preliminary study so that it is only done for objects with two dimensions with square and circular shapes. From the research that has been done, the measurement with the camera gives results that are almost the same as the use of calipers where the standard deviation fluctuates from 0.3 to 23.8 for circles and 0.54 to 32.05 for squares. Furthermore, the time needed to do one measurement process with the camera ranges from 201 ms to 338 ms whereas using the calipers takes 3 to 5s

Abstract

This paper focuses on fiqh (Islamic jurisprudence) learning at the high school level. The aim of the research is to measure the extent to which the achievement of fiqh learning at the high school level can be improved with the blended learning method. Concept analysis method is used to understand the concept of blended learning and explain its implementation in the field. This research is a class action research which refers to the Kemmis model consisting of four components namely planning, implementation, observation and reflection. It is expected that the blended learning method can improve the achievement of fiqh learning at the high school level. The research found that in the first phase of classroom action research, students have not been able to adjust themselves to learning using the blended learning method, especially with the Kahoot application. Most students are still fixated on conventional learning. Basically, however, the blended learning method can generate high attractiveness for students. Enthusiasm and focus on learning become higher. The feedback obtained shows that 100% of students claim to have learned something, 100% recommend it to be reused and 80% welcome this method with fun. The study suggests that the composition in the placement between direct communication with face to face and online must be appropriate, so that an improvement in fiqh learning can be achieved. Keywords: blended learning, fiqh learning, learning outcome

Abstract

The use of groundwater as a source of fresh water to the people would become a problem when it contains of Fe and Mn. This happens because in the ground water there is no directly contact with the air outside and the weathering of rocks, so that Fe and Mn in the ground water is still soluble. Meanwhile the amount of Fe and Mn in the ground is never the same in every location. This case could be some impacts to people?s kidney health. In this study, content of Fe and Mn in the ground water will be reduced by using Clay filter media. This study uses 3 wells water samples character with different level of Fe and Mn in sample A is 0.001 mg / l Fe, 0.16 mg / l Mn, sample is B 0.019 mg / l Fe, 0.05 mg / l Mn, and sample C is 3,242 mg / l Fe, 0.27 mg / l Mn. The height level of water influence to the Clay filter becomes the consideration in this study, they are 50 cm, 100 cm and 150 cm. Clay Filter is operated for 12 hours continuously with taking the reuslt of filtration sampling per 2 hours. Based on the research, this study finds the operating time to decrease the concentration of Fe and Mn with Clay Filter optimally from the three height levels in all kinds of different water samples and its categorization has reached 100% at the fourth hours.

Abstract

Seiring dengan peningkatan jumlah penduduk di daerah pesisir, tekanan terhadap ekosistem pantai semakin meningkat pula.  Untuk mengetahui dampak dari aktifitas anthropogenik terhadap status hara (karbon, nitrogen dan fosfor) pada lamun telah dilaksanakan penelitian pada dua pulau di Kepulauan Spermonde yakni Pulau Barranglompo dan Bonebatang.  Kedua pulau ini mendapat tekanan anthropogenik berbeda. Sampel diambil dari daun lamun Enhalus acoroides pada tiga stasiun dengan jarak berbeda dari garis pantai pada masing-masing pulau.  Hasil pengukuran hara menunjukkan bahwa konsentrasi nitrogen di Pulau Barranglompo jauh lebih tinggi dibandingkan Pulau Bonebatang.  Nilai rasio C:N yang lebih rendah dan nilai rasio N:P yang lebih tinggi di Pulau Barranglompo memperkuat hal ini. Perbedaan ini mengindikasikan pengaruh dari pengayaan hara akibat aktifitas anthropogenik yang semakin meningkat. Hal ini didukung oleh nilai Total Padatan tersuspensi yang jauh lebih tinggi di Pulau Barranglompo dibandingkan Pulau Bonebatang. Aktifitas anthropogenik yang paling potensial mempengaruhi komposisi hara di Pulau Barranglompo adalah pembuangan sampah rumah tangga dan aliran limbah cair dari rumah penduduk di sekitar pantai. Kata kunci: lamun, hara, rasio C:N:P, aktifitas anthropogenik, Barranglompo, Bonebatang As human population increase in coastal areas, significant pressure to the coastal ecosystem increase as well.  In order to reveal possible impacts of anthropogenic activities to the nutrient status of seagrasses, a study has been done in two small islands within Spermonde Archipelago i.e. Barranglompo and Bonebatang Islands. Currently, these two islands are facing different anthropogenic pressure.  Samples of seagrass Enhalus acoroides were collected from three stations based on their different distances from the shoreline.  Results of the nutrient measurements showed that nitrogen concentrations in Barranglompo Island were significantly higher than those in Bonebatang Island.  This was supported by lower C:N ratios and higher N:P ratios in Barranglompo Island.  This difference indicated influence of nutrient enrichment due to increased anthropogenic activities.  Significantly higher Total Suspended Solid (TSS) values were also a strong evidence of this process.  Potential anthropogenic activities affecting nutrient composition in Barranglompo Island are domestic sewage disposal and drainage of liquid household sewage. Key words: seagrass, nutrient, C:N:P ratio, anthropogenic activities, Barranglompo,  Bonebatang

Abstract

This study aims to analyze the effect of zakah revenues and job creation on poverty rates. Using a panel data set of 23 districts in Aceh for the period of 2011-2017, a fixed-effect method of the panel regression model and the Granger causality test was utilized to analyze the functional relationships between the three variables. The study found out that the zakah revenue and job creation have a negative and significant effect on poverty rates. However, the negative effect of job creation on poverty rates is greater than the negative effect of zakah revenues. The Granger causality test indicates that there is bidirectional causality between poverty rates and zakah revenues and between employment creation and poverty rates. Conversely, there is no causality between zakah revenues and job creations.

Abstract

Profil asimetris adalah distribusi kecepatan aliran pada penampang melintang pipa yang acak dan alirannya belum berkembang mantap. Aliran asimetris menyebabkan timbulnya galat hingga 11% pada hampir semua alat ukur flowmeter. Solusi agar pengukuran aliran pada fluida berprofil asimetris tetap akurat adalah dengan mengetahui langsung profil kecepatan aliran karena mampu memberikan informasi distribusi kecepatan aliran dengan tepat. Menggunakan Hot-wire Anemometer, mengoptimalkan penempatan lokasi pencuplikan data pada penampang melintang pipa dan memanfaatkan metoda interpolasi kubik, diperoleh hasil pengukuran yang akurat ketika mengukur aliran asimetris dengan galat rata-rata adalah 1,96 % dan profil rekonstruksi yang diperoleh menyerupai profil yang diukur.
