Abstract

Puskesmas (Pusat Kesehatan Masyarakat) are the direct service community of government health agencies to serve and should pay attention to the level of service to patients. The problems mostly is the lack of knowledge and skills of medical personnel and administrative personnel in dealing with patients and inform patient illness. To improve the service to the patient is the concept of DMAIC improvement with five stages. In this research, the worst cause of service is that the employees of Puskesmas X do not have the knowledge to answer the patient's question with the percentage of 62.8%. So the improvement is focused on the five causes of disabled services, which occurred in December 2016. Kata kunci: Kualitas Layanan, Lean Service, Six Sigma

Abstract

This study aims to determine the effect of variations in the welding current to tensile strength and hardness welding SMAW with electrode E7016 on plate carbon steel ASTM A36 with a thickness 10 mm. large variations in use of welding current is 90 amps, 100 amps, 110 amps and 120 amps. This research was carried out by making spesiment test with the variation of welding current at 90 amperes, 100 amperes, 110 amperes and 120 amperes hereinafter spesiment test carried tensile testing and hardness to seek information influences that caused by the variation of welding current to the tensile strength and hardness of the welded joints. The results showed that the highest tensile strength (Ultimate Tensile Strength) were obtained on a sample of 110 amperes with value - average UTS at 467.78 MPa. While the highest hardness values obtained on a sample of 120 amperes with value - average in the region of 191 HV HAZ and in the region of 228 HV Weld metal.

Abstract

Winterizing is a limited form separation of saturated fatty acids and unsaturated fatty acids, to remove wax and fat has a higher boiling point. To obtain the product specifications, parameters must be control is cloud point ≤ 7 oC. Response surface method use as a tool to determine the optimum operating conditions in the process of winterizing, the control parameter C16 feed composition, temperature, time. Feed C16 varied 19%, 20%, 21%, temperature varied 10 oC, 10 oC, 11 °C, time varied 14 hours, 14,5 hours, 15 hours for order I and central composite disgn in order II. The results showed feed C16 and temperature are significantly influence the cloud point. Model is Y = 6.920 + 1,429X1 0,636X2 + 1,030X22 1,080X12 - 0,650X1X2. Winterizing process optimization point C16 feed obtained 19.20% and temperature 9.93 oC.

Abstract

This research is motivated by frequently some employees in process wheelblasting and Spray in idle state. After analyzed, it can be identified that the amount of idle time is aused by the material transfer process (Soleplate) which is still done manually which takes 18.5 seconds per unit (bottleneck). the purpose of this study are: To determine whether the conveyor can reduce waiting time in the Steam Promoter line or not. In this study, the anthropometry method used to determine the height of the conveyor and Westinghouse method is used to determine the magnitude of the rating factor and the amount of allowance. The results of this research are: a) The most ideal conveyor height is 90cm b) standard time of manual transfer (before improvement) is 28.55 seconds, c) standard transfer time using conveyor (after improvement) is 17.43 seconds, d) The difference of Standard time using manual transport Vs using conveyor is 11,12 second, e) by using conveyor, waiting time can be reduced.

Abstract

Jenang is one of the special food from the Kudus City of Central Java Province. The process of making jenang through several stages, namely the process of material insertion, the process of mixing the material while cooked with the mix, the process of printing in a baking sheet and packaging process. In the process of this jenang packaging is done by workers who sit on a wooden chair with no foam pads and no back support. Sitting position, judging from the aspect of ergonomics sitting position is less comfortable. Therefore, it is necessary to design seats for ergonomic jenang packaging operators. The method used in designing this chair is by descriptive analysis, with the seat dimension approach to anthropometry of worker's body. Required data include anthropometric data of workers' packaging body dimensions and data obtained from existing research. Then the data is processed to be applied to the design. This design is a prototype that will be measured and applied to the packaging hood of the worker. The purpose of this research is applying ergonomic chair to jenang packaging worker, so it is expected to improve work position of jenang packaging worker and reduce discomfort that can cause fatigue. The result of the research shows that with the application of ergonomic chair design to the jenang packaging worker, there is improvement of work position on the jenang packaging worker and decrease the level of discomfort that happened to the neck, back, round, buttock and elbow of the jenang packaging worker.

Abstract

Measure natural electric voltage at surface used Self-Potential method. Self-Potential one of the methods used to look at subsurface water flow. The negative or positive sign of potential is an important factor for the interpretation of Self-potential anomalies. The finite element technique is applied to model the velocity of water flow, current source, and potential value distribution in the form of 2-D profile. Finite element technique was chosen to solve the problem of boundary conditions and differential equations for Self-Potential modeling. Modeling current sources are obtained by intermediate gradient operation and water flow velocity . From the result of modeling, we get the value of water flow velocity between 10-6 - 10-4 m/s, current source, potential distribution, and potential response on the topography of the slope. Each topography produced different potential response forms, due to the electrokinetic effect. The water flow in the area with slopes topography often causes inundation due to inadequate absorption area, thus causing the grinding of the soil and destroying the road. From the results of this modeling is designed a good water absorption area using visio.

Abstract

Hujan merupakan salah satu sumber air bagi kehidupan di bumi. Kehadiran hujan menjadi hal yang sangat penting bagi kehidupan tanaman dan hewan karena dengan kehadiran hujan akan terpenuhi kebutuhan mereka akan air. Selain kuantitas air hujan, kualitas air hujanpun menjadi peranan penting bagi kehidupan dibumi. Air hujan yang terkontaminasi akan mengakibatkan kualitas air hujan menurun. Kontaminasi ini dapat berupa fisik, kimiawi dan biologis. Faktor fisik yang dapat membuat kualitas air hujan menurun adalah nilai acidity level (pH). Nilai acidity level yang rendah dapat menyebabkan terjadinya hujan asam yang berbahaya bagi tanaman, hewan bahkan manusia. Penelitian ini berfokus pada kualitas air hujan dilihat dari nilai acidity levelnya. Hal ini untuk melihat seberapa besar pengaruh polusi industri yang berkembang di Cilacap terhadap kualitas air hujan yang dihasilkan. Metode yang digunakan pada penelitian ini menggunakan metode analisis yang berdasarkan SNI 06-2413-1991 dengan sampel air hujan yang berasal dari 15 titik di kabupaten Cilacap. Analisis yang didapatkan dari 15 sampel ini menunjukkan bahwa air hujan dikabupaten Cilacap memiliki pH 4,5 – 7,6. Nilai pH air Hujan <5 terjadi di daerah Trenggiling, Manunggal, Karangtalun dan Kutawaru.
