RANCANG BANGUN ELECTRIC ROTARY TABLE BERBASIS INVERTER GUNA MENURUNKAN CYCLE TIME PADA PRODUKSI PIPA KAPILER
Get PDFCycle Time merupakan hal yang harus diperhatikan dalam waktu produksi, Cycle Time yang baik akan menunjang target yang harus terpenuhi, bahkan jika Cycle Time menurun maka produksi juga akan meningkat dan omset perusahaan juga akan meningkat. Pada studi kasus PT Arisamandiri Pratama yang salah satu produksinya berupa part AC yaitu pipa kapiler yang masih mengunakan meja putar manual untuk memutar pipa yang akan dilakukan proses las sehingga tidak mampu mencapai target 800 part/jam atau 6400 part/hari. Dengan rancang bangun Electric Rotary Table yang diputar dengan menggunakan motor listrik dapat menurunkan Cycle Time sebesar 17,38% dengan kapasitas 935 part/jam, hal ini melebihi target produksi sebesar 800 part/ja
PERBANDINGAN QUANTITY TAKE-OFF BAJA TULANGAN ANTARA METODA KONVENSIONAL TERHADAP METODA BIM 5D CUBICOST PADA STRUKTUR GEDUNG FASILITAS PERKERETAAPIAN MANGGARAI
Get PDFAbstrakBIM 5D merupakan bagian dari dimensi BIM yang berhubungan dengan perhitungan volume pekerjaan dan optimasi, dimana contoh software untuk menjalankan BIM 5D adalah Cubicost. Cubicost merupakan produk dari PT. Glodon yang terdiri dari beberapa software dengan berbagai macam fungsi. Pada studi ini akan dilaksanakan menggunakan produk Cubicost yaitu TAS dan TRB yang digunakan untuk menghitung perhitungan volume pekerjaan secara cepat, detail dan akurat, yang akan dibandingkan dengan metoda konvensiol pada Proyek Pembangunan Fasilitas Perkeretaapian Manggarai sampai dengan Jatinegara. Hasil penelitian menunjukkan bahwa hasil perhitungan kedua metoda ini tidak identik sama yaitu hasil perhitungan TAS dan TRB memperoleh hasil volume baja tulangan sebesar 1.055.303,98 kg, sedangkan hasil perhitungan konvensional sebesar 1.052.779,36 kg, sehingga diperoleh selisih sebesar 2.966,70 kg, jika di persentasekan akan didapatkan selisih sebesar 0,28%. Selisih perhitungan tersebut terbilang kecil dan masuk toleransi, akan tetapi akurasi tersebut bisa lebih ditingkatkan lagi dengan pemodelan TAS dan TRB yang lebih baik dan detail.Kata kunci: Perhitungan Volume Pekerjaan, Baja Tulangan, Cubicost TAS dan TRB.Abstract5D BIM is a dimension of BIM that focuses on quantity take-off and optimization. One software example for implementing 5D BIM is Cubicost, a product of PT. Glodon. Cubicost consists of several software with various functionalities. This study utilizes two Cubicost software, TAS and TRB, to calculate quantity take-off quickly, in detail, and accurately. The results are then compared with the conventional method in the Manggarai-Jatinegara Railway Development Project. The research results show that the calculation results of both methods are not identical. The calculation results of TAS and TRB obtained a rebar volume of 1,055,303.98 kg, while the conventional calculation result was 1,052,779.36 kg, resulting in a difference of 2,966.70 kg. In percentage, the difference is 0.28%. Although the calculation difference is relatively small and falls within the tolerance, the accuracy can be further improved with better and more detailed TAS and TRB modeling.Keywords: Quantity take-off, Reinforcement Bar, Cubicost TAS dan TR

Implementation Control And Monitoring System Water Quality of Koi Fish Ponds Based On the Internet Of Things
No full textKoi fish is one of the ornamental fish that is in great demand and has a fairly high price. Water quality plays an important role in the success of keeping koi fish. The quality of koi fish water must be at an ideal temperature of 25-30 °C and an acidity level or pH of 7-8 pH. The level of salt contained in water for koi fish must also be considered. A pond with a size of 200 x 50 x 100 cm requires a salt content of 1 to 2 ppm. Giving this salt is done to prevent the growth of bacteria in the koi pond which can come at any time. Ignorance of pond owners about the value and condition of water quality can disrupt the health of koi fish which can cause death. Based on these problems, the authors created a water quality control and monitoring system in koi fish ponds. The system created consists of a pH sensor, temperature sensor, and salinity sensor, and uses the Message Queuing Telemetry Transport (MQTT) protocol. The process of sending data to the IoT platform using a WiFi network. Based on the temperature sensor test, there is an average error of 1.4% with a sensor accuracy level of 98.6%. Testing the pH sensor and salinity sensor using the linear regression method. As for the pH sensor, the average error is 2% with an accuracy rate of 98%. The results of the salinity sensor test obtained an average error value of 7.6% with an accuracy rate of 92.3%. Then in the MQTT protocol, the parameters for delay and jitter have a bad category, while throughput has a moderate category, and packet loss has a very good category according to the TIPHON standard.
