The raw material used by this company is the result of refining petroleum in the form of naphtha and crude c4. In this discussion, there was often a buildup of ships in the Anchorage area before leaning on the Jetty because there was no ready storage of raw materials to receive cargo. To overcome the problem in inventory naphtha, it uses the exponential smoothing method by finding the smallest MAD. And to overcome the difficulty in C4 crude using the reorder point method to determine the existing safety stock. Based on the results of calculations using the exponential smoothing method, the smallest MAD is obtained which is 5099.66 with a value of Î± 0.9. And with the estimate of safety stock for naphtha tanks that is equal to 11898.5 tons with a safety factor of 95%. The results of the reorder point calculation on Crude C4 obtained a safety stock of 1959 Tons with ROP (Reorder Point) of 3959 Tons which means that when supplies have reached ROP, it is recommended to send the Crude C4 product to the shipment so that excessive production does not accumulate in the tank.

Foaming Agent company is a company engaged in the chemical industrial manufacturing, especially the additive industry for plastic and synthetic rubber. In the production process, the Foaming Agent Company has a problem with one of its products, Azodicarbonamide (ADCA). The number of defects caused becomes a problem primarily related to the course of production and the relationship with the customer. The research was conducted using the Six Sigma method by implementing DMAIC (Define, Measure, Analyze, Improve, Control). This study aims to identify the factors that cause defects and the most optimal choice of options to increase the level of sigma in the ADCA production process. Based on the results the most significant aspects that cause defects in ADCA products is Average Particle Size; 66.77% of the overall production defects. The sigma level that obtained before and after the improvisation is 3.68 and 4.03 with the average achieved savings per month are Rp.600 million. The results of the gradual decrease in defects showed that the options implemented at the improvisation stage were successful, but still needed improvisation so that the companys performance can be even better

CV. SDH Cilegon is engaged in construction services in carrying out production process activities; companies still experience product failures caused by humans, raw materials, machinery, methods and the environment and factors that often occur are humans because all production activities are carried out by humans, including machine operation. For work methods, returning to human factors again where the wrong approach to work can result in disability in production. Raw materials and the environment also affect the defects that arise. Sixty-three units dent failures that often occur; there are foreign bodies of 47 units, imperfect shape of 33 units, so the total number of defects is 143 units.

Penerapan Lean Manufacturing untuk Mengurangi Waste pada Produksi Absorbent Ravizar, Agung; Rosihin, Rosihin

This study aims to reduce the waste that occurs on each workstation and has an impact on increasing productivity and reducing production costs caused by waste that occurs during production. The data used for this study is quantitative data obtained by direct observation to the relevant departments regarding the problem of identifying waste that occurs â data taken from observations as much as 30 times the collection of data and historical data used from January 2016 to June 2017. By using the value stream mapping method on lean manufacturing, it can be seen that there are five types of waste from the existing seven waste. The five wastes are unnecessary motion, waiting, reject, transportation and in-process processes. From the results of the value stream mapping carried out a reduction in waste on each workstation with a total reduction of waste that occurs at 66.97 tons / year or 18.6% on waste gel and 88.8 tons / year or 19.3% at waste powder and there was a reduction in the changeover process for 45 minutes or 12.16% of the total changeover time before the improvement. Also, there was also an increase in the production process speed of 2 minutes 47 seconds or 4.52% from the lead time of the previous production process, 61 minutes 34 seconds to 58 minutes 47 seconds.

The objectives of this study were to analyze the  language acquisition for conjoined-clauses in speaking of an Indonesian child who got exposures from English cartoon films and opportunities to practice with his linguistic environment. This research was qualitative research and it was longitudinal study where the data were collected for twelve months ( April 2016 ? March 2017) by recording his spontaneous speech  when the subject was 4.10 until 5,9 years old. The data were transcribed then analyzed to see the development of his English syntactic constructions of conjoined-clause. The finding of the research showed that the process of language acquisition of the subject closely followed the universal principles of language acquisition for conjoined ? clauses. By giving exposure of English cartoon film everyday for three  hours and opportunities to practice with his linguistic environments, the acquisition of foreign language learner can be similar to first or second language learner.

Analisis Pengendalian Kualitas Super Absorbent Polymer Dengan Menggunakan Metode Six Sigma Rosihin, Rosihin; Mujaddid Ulinnuha, Laksamana; Cahyadi, Dadi

Quality control is an effort to increase customer satisfaction and minimize damage. Super Absorbent Polymer which is a product as a raw material for making baby diapers / elderly and sanitary napkins. In Super Absorbent Polymer, defects usually found in the colour contamination that there is a dark colour on the product, print labels mistakes and packaging defects. This study aims to determine the value of DPMO and sigma level, identify the efforts which is taken to reduce disability, identify the types of disability, and find the main factors causing disability. Six Sigma method is used to analyze data with define, measure, analyze, improve and control. The quantitative data obtained by direct observation of quality problems. By using the method of six sigma can be seen that the quality of the resulting product is quite good that is 3.07 sigma with a damage rate of 58,624 for a million production (DPMO). The three highest defect product causes are color contamination of 93.34%, misprint of 3.55%, and packaging damage as much as 3.11%. The main factor causing defects is the engine factor for the type of colour contamination defect,. The type of improper defects in the packaging labels and main factor for the packaging defects is the human factor.kecacatan rusaknya kemasan faktor utama ialah faktor manusia.
