Controlling the supply of raw materials belt conveyor is a very important management function because it is a vital company investment, both in terms of value and future prospects. Well-implemented inventory control management can trigger a company's success in production. In manufacturing companies there is often a delay in the arrival of material arrival due to various things, such as the bullwhip effect between the company with suppliers, companies with distributors or companies with buyers. The focus of this research is to know how big the occurrence of bullwhip effect and how to decrease the bullwhip effect that already happened. From the calculation results obtained a decrease in the value of the bullwhip effect from the original to PU White products 2,786 to 1,524, blue PU products 3,297 to 1,455, and PVC Green 2.025 to 1.5794.

Determination of poor families in the poverty database is still less than perfect. There is still no multi criteria decision making (MCDM) technique in the grouping of poor families, making the results of the criteria in grouping poor families still far from expectations. So, this article discusses the use of the multi criteria decision making (MCDM) technique for grouping poor families in the poverty database in the Malang district. Fuzzy logic is one technique of MCDM which is commonly used for affirmation of decisions. In a random sampling of 35 families taken from the Malang District poverty database, the classification that was originally obtained was only obtained by 2 (two) classifications of poor families, namely: very poor families and poor families. But after it was calculated using the Fuzzy Logic method, it was found 3 (three) classifications of poor families, namely very poor families, poor families, and almost poor families. The magnitude of the distribution of the poor family classification is: 17 (seventeen) very poor families which previously were 14 (fourteen), 17 (seventeen) families were categorized as poor families that were previously 21 (twenty one), and 1 (one) family in the category of near-poor families that were not previously found. With these results, it can be concluded that the Fuzzy Logic method can and is able to provide better and more diverse results in determining poor families in the Malang District poverty database.

In an increasingly advanced era, allproperty or home furniture is required to have arenewable innovation and efficiency. This is becauseproperty or home furniture currently has a very largemass or size. Large furniture sizes such as chairs andtables have an average area of 500cm2. Almost 90% ofIndonesian people have tables and chairs as the contentsof their household furniture. Not only functioned athome, in restaurants, cafes, malls, offices, in parks andall places where if there is interaction between humans,there must be chairs and tables as places for interaction.But sometimes the owners of chairs and tables oftencomplain about the size of the tables and chairs, so they need a large enough area to place these two items. Theproblem that exists in society today is the narrowing ofempty land in one place. Sometimes there is homefurniture that is not ergonomic, such as a chair that istoo high, a table that is too low and so on. By using thisanthopometric method, the measurements obtainedinclude a chair along the 95th percentile 25 cm, chairlength 33 cm 95th percentile, table length 68 cm 5thpercentile, chair height 39 cm 5th percentile, table height69 cm 5th percentile, and finally lower surface height. atable of 54 cm on the 95th percentile, and it is hoped thatthe manufacture of a chair flexibility table productdesign can overcome all the problems of land limitationsthat exist in today's society.

At the location of public queuing services, there are often many customers lining up to be served immediately. This problem also exists in the process of transporting light bricks at PT. Priority One Indonesia. It is not efficient because of the time they can spend doing more important things. In this case, a technology is needed to make it easier for customers to queue. In this study, a web-based or online queuing application called the LiQu application was designed. The output of the LiQu application system is to make the queuing process can be done online, and to conduct customer satisfaction research on the performance of the light brick transportation queue service at PT. Priority One Indonesia. Then perform 2 analysis tests, namely Usability analysis calculating the results of the questionnaire using the Likert Scale Inteval method and Reliability analysis with WAPT 3.1 software testing then calculations using the Nelson model.

The availability of pure water is a basic requirement of the Company,which is one of the main requirements for the production process in order for the Company to produce the cream.In order to meet the production needs ,the Company must have a Water Treatment Plant with good performance. A good Water Treatment Plant can produce a lot of pure water to meet the water requirements required by the Company. This research is needed to get a good Water Treatment Plant performance to improve the pure water of Company XYZ. This research uses FMEA (Failure Mode and Effects Analysis) method to classify which components require maintenance and scheduling . Scheduling in this research using RCM (Realibility Center Maintenance) method. In this research yield MTTRs and filter 0,48 hour,bag filter 0,68 hour, cartridge filter 1,22 hour.MTTF sanfilter 684 hours,bag filter 190.3hours,cartridge filter 236,8 hours.And MTBFs and filter with an average of 708 hours,bag filters with an average of 214.8 hours and a filter cartridge with an average of 260.8hours per year. In addition to MTTR, MTTF and MTBF other research is reliability (realibility) sand filter with value 0,178527412, bag filter with value 0,005394050, and cartridge filter with value 0,008884653.

Storage of finished goods is one of the important factors needed by a company, both offline and online manufacturing. The problem that often occurs is the lack of area and inadequate warehouse locations for storing finished goods. This problem is also found in the activities of storing finished goods in shipping expeditions. The condition of the warehouse which was initially less efficient was due to the location of the warehouse being less spacious, the absence of safety equipment and also areas prone to flooding. The goal to be achieved is to choose the optimal warehouse location from several existing alternatives. The method used is the Analytical Hierarchy Process (AHP) method to develop a hierarchy of logistics center location selection. Research variables using criteria include distance, cost, facilities, geographical position and warehouse area. The results of data processing produce the highest criterion weight value of 0.3228, namely the area of the warehouse and the smallest criterion weight of 0.0417, namely the cost criterion. In addition, the highest value of the work alternative is 0.4085 on the SPILL warehousing alternative and the smallest value is 0.2749 on the Rungkut Industri alternative.
