Integrated Lab Journal Vol. 5 No. 2 (2017)
Publisher : UIN Sunan Kalijaga Yogyakarta

Manajemen persediaan merupakan masalah penting yang dihadapi oleh perusahaan. Untuk mendukung kelancaran produksi yang pada akhirnya akan berpengaruh pada kelancaran pemenuhan permintaan konsumen maka manajemen harus selalu berusaha menjamin ketersediaan bahan. Manajemen persediaan mengharuskan adanya pengelolaan persediaan untuk merencanakan dan mengendalikan persediaan pada tingkat yang optimum, menentukan kualitas persediaan yang wajar untuk memenuhi kebutuhan pengolahan/produksi atas suatu dasar yang terjadwal dan sesuai dengan order pelanggan. Berdasarkan hasil analisa data yang telah dilakukan mengenai jumlah persediaan (inventory) pada perusahaan ED Alumunium diperoleh kesimpulan sebagai berikut, untuk bahan baku Ingot, jika melihat dari perbandingan metode Economic Order Quantity (EOQ) dan Re Order Point (ROP) diperoleh hasil bahwa jumlah persediaan bahan baku pada bahan ingot dengan metode ROP memiliki jumlah pemesanan lebih kecil yaitu sebesar 2.784 kg. Sedangkan untuk bahan baku scrap, diperoleh hasil bahwa jumlah persediaan dengan metode ROP juga memiliki jmlah pemesanan lebih kecil yaitu sebesar 310 kg. Sehingga untuk persediaan rata-rata, pada bahan baku scrap memiliki jumlah persediaan rata-rata lebih banyak yaitu sebesar 2802,5 kg. Biaya pemesanan pada bahan baku ingot memiliki nilai yang lebih besar yaitu dapat menghasilkan bahan baku dengan biaya rata-rata sebesar Rp 11.214.871,30 di dalam ruang penyimpanan. Jumlah stok atau persediaan di perusahaan ED Alumunium, untuk bahan baku ingot menghabiskan total biaya untuk persediaan adalah sebesar Rp 22.430.901,12, sedangkan untuk bahan baku scrap sebesar Rp 1.064.260,75.

Research on heavy metals (iron and copper) ions uptake in wastewater using papaya seed powder has been conducted. The purpose of this study was to provide solutions on handling and processing of heavy metal waste in the laboratory. The adsorption method is used for this purpose. Activation of the adsorbent was carried out to determine the effectiveness of the unactivated and activated adsorbents.Activation is done using a neutral activator (aquadest). Papaya seed as the adsorbent agent (both un-activated and activated ones) was used in four mass variations in order to determine the optimum mass of papaya seed powder to absorb the heavy metals. The results show that the optimum adsorbent mass was 2 grams for both metal ions (iron and copper). The activated adsorbent is more effective in the adsorption process. The adsorption efficiency of iron (Fe) metal ions in wastewater was 58.80%, the adsorption capacity value was 257.10 mg/g. While the adsorption efficiency of copper (Cu) metal ions in wastewater was 90.70%, the adsorption capacity value was 345.04mg/g.

Publisher : UIN Sunan Kalijaga Yogyakarta

Perencanaan agregat merupakan cara untuk memperkirakan jumlah output yang akan diproduksi untuk memenuhi permintaan selama periode perencanaan (3 sampai 18 bulan) ke depan dan disesuaikan dengan kapasitas produksi perusahaan. Perencanaan agregat memungkinkan perusahaan untuk menyusun suatu cara pemanfaatan sumber daya perusahaan secara optimal, agar dapat mencapai kapasitas yang efektif dan efisien yang dibuat berdasarkan ramalan permintaan di masa yang akan datang. Efektif yang berarti keselarasan antara perencanaan dengan hasil yang didapat, sedangkan efisien berarti mampu memproduksi suatu output tertentu dengan sumber daya yang ada dengan seminimal mungkin. Berdasarkan perhitungan atau perencanaan agregat yang telah dilakukan menggunakan data permintaan dan produksi perusahaan C-MAXI ALLOYCAST periode sebelumnya diketahui bahwa metode yang paling baik yang dapat digunakan dalam proses produksi perusahaan yaitu metode chase strategy, metode ini digunakan dengan cara menambah atau mengurangi jumlah tenaga kerja berdasarkan jumlah permintaan konsumen. Dengan menggunakan chase strategy maka biaya yang dikeluarkan perusahaan lebih sedikit jika diibandingkan dengan metode metode lainnya. Biaya yang dikeluarkan berdasarkan pemilihan metode terbaik untuk produk box listrik sebesar Rp 1.000.272, untuk produk alat rumah sakit sebesar Rp 902.764, dan untuk produk peralatan rumah tangga sebesar Rp 521.892.

Publisher : UIN Sunan Kalijaga Yogyakarta

This research aims to simplify the equation of Fraunhofer Difraction Intensity for the circular slit analyticaly so that it can be easily applied in the calculation of computing. Fraunhofer diffraction event for the circular slitis expressed as the ratio between Bessel functions 1 and variables with interval 0 to infinity so may result divided by zero in the calculation of computing. Solution analytical calculations done by outlining the Bessel function 1 becomes the Bessel function 0 and Bessel functions 2. The results of analytical calculations and computations, Fraunhofer diffraction pattern is obtained in the form of the intensity curve which is then displayed in 3D to get the diffraction pattern.From the results of this research concluded that the larger radius gap, resulting the diffraction pattern is getting narrower. And the greater the wavelength of the light source, resulting diffraction pattern is widening.

Publisher : UIN Sunan Kalijaga Yogyakarta

Statistics Process Control (SPC) is a tool used for on-line quality control in mass production. Control Charts or control charts are selected from statistical sampling theory that is effectively applied in SPC. This paper will explain the function and method of applying one of the tools in SPC to observe the physical and chemical properties of wastewater from air conditioner (AC). The physical and chemical properties observed were TDS, pH, DHL, temperature, and turbidity. The results of the application of SPC by using the control chart shows that the control chart makes it easy for the observer to do the analysis process of the observation data. The results obtained can be taken from SPC on the observation of the physical and chemical properties of AC waste water in the Environmental Laboratory of the Faculty of Biology, Jenderal Soedirman University, namely the average value of each parameter, namely TDS = (4.85 mg / L), pH = 6.53, DHL = 0.00117 (ms), temperature = 23.3C, Turbidity = 0.4265 (NTU). Referring to the requirements of distilled water, the AC waste water is still suitable for use as a substitute for distilled water. The ploting of data on the Xbar-chart TDS data, pH, and Turbidity is within the control limit with a confidence level of 99%, while the Temperature and DHL data are within the control limit with a 95% confidence level. While the results of plotting the data on the Rbar-chart of TDS, DHL, and Temperature data are within the control limits with a 99% confidence level, while the pH and Turbidity data are within the control limits with a 95% confidence level.

The Atwood machine is the equipment consists of two masses connected with string or rope on a pulley fixed. In the Atwood best practical implementation by using a stopwatch timekeeping is done manually lead time calculations are inaccurate because it depends on the precision of the practitioner. Manufacture of electronic equipment by utilizing light-sensitive sensor that can automatically record the time interval in experiments using the calculation time is expected to minimize these inaccuracies. This electronic equipment uses the principle of the switch transistor, where the transistor is in two circumstances, namely the state of saturation and discontinuity. Specifications of this electronic circuit when the infrared light is not blocked by an object, the resulting output voltage of 11.07 volts and when the infrared light is blocked by an object, the output voltage drops to 1.2 volts using input voltage of 12 volts. From the research could have made an electronic device that can be used to record time lapse automatically by using a light-sensitive sensor based phototransistor. Series that has been created can be utilized in the best lab Atwood. The result of the calculation of the acceleration of gravity by using the self-timer on the plane practicum Atwood is 9.791 m / s2.
