Abstract
In Tofus micro and medium enterprises, there is one traditional activity that is conducted repeatedly, called the cutting process. This cutting process is done by using a kitchen knife which makes it not efficient and can cause fatigue for operators. In addition, there is also the possibility of different sizes of tofu pieces because there is no measuring tools to cut it. This is because operators just follow the mold flow on the tofu. This study is aimed to make a product plan for tofu cutting tools. The Analytical Hierarchy Process was used as a research method in this study. This method begins with conducting interviews regarding the choices in level 1, 2 and 3 actions to several respondents. The respondents must choose and give an assessment on a scale of 1 to 9. The result taken from a variety of alternative solutions, which is made based on requirements specifications, is that the product of the tofu cutting tool is selected with materials made of pine wood, strings, handles, naples, and naple bolts. Moreover, the product produced will have a size of 52 x 52 cm2. The product design is based on material and tool specifications to produce a simple design. This is made so that the tofu cutting tool is easy to use as well as low cost.

Abstract
This study aims to implement a decision-making approach in selecting electric generators in manufacturing companies. The first step is to compile a set of criteria that is matched with the companys preferences. The next step is to apply the Analytic Hierarchy Process (AHP) to determine the weight of the criteria using pairwise comparations. Furthermore, simple additive weighting (SAW) is used to select the best alternative using quantitative data. The study was conducted at a manufacturing company engaged in textile in Indonesia. The results showed that there were six criteria used to select electric generators, namely product prices, capacity, reliability, maintenance costs, ease of service and service life. The application of this approach has been able to help decision makers in the group decision-making process effectively and efficiently. Besides that, the results of this study have been able to utilize qualitative and quantitative data to produce the best solution in the selection of alternatives.

Abstract
Permeability is an important reservoir property but is difficult to predict. Accurate measurement of permeability values can be obtained from core data analysis. However, this analysis is not possible to do at all interval wells in the field, so that permeability information becomes incomplete. Then, the use of artificial neural network methods can be an alternative to predict the incomplete permeability value. This study used 191 of sandstone core samples from Upper Cibulakan Formation in the North West Java Basin. These core data were used to determine hydraulic flow unit (HFU) from the reservoir, and to obtain a relationship between porosity and permeability for each HFU. The application of artificial neural network method is done by building a database of flow zone indicator (FZI) based on its relationship with log data. From this FZI value, the HFU class can be known. Afterward, the permeability value can be obtained according to the equation of the relationship between porosity and permeability at each HFU that had been generated. Based on this study, the result of permeability value is not much different from core data at the same depth, so that this method can be applied to obtain the permeability in uncored intervals.

Abstract
The volumetric method is the initial method used in calculating hydrocabon reserves obtained from exploration stage obtained geological data from a field in the oil and gas industry. The hydrocabon reserve calculation obtained from volumetric method is the result of interpretation data, such as seismic and logging data that have a small range of trust, in this study estimated hydrocarbon reserves in the XY formation gas reservoir using material balance method and P/Z method in assessing optimism or pessimism of the reserve value generated from volumetric method. material balance method and P/Z method were chosen as a reliable method because it has better accuracy data such as pressure measurement data, reservoir rock and fluid analysis data, and cumulative production measurement data compared to interpretation data on volumetric method. From this research, it can be concluded that the reserve value produced by the volumetric method is more pessimistic than the reserve value using material balance method and P/Z method. By knowing pessimism of the results of the volumetric backup method for the other two methods, it will affect the amount of oil and gas industry reserves so that geological modeling needs to be done again after more accurate data is obtained

Abstract
Multivariate Control Charts is an effective tool in Statistical Process Control to identify either an out-of-control process or in-control process. Hotelling T2 control chart is a quite popular and widely used technique in this field. However, its performance is deteriorated when the underlying distribution of the quality characteristics is not following the multivariate normal distribution. Multivariate control chart usually recommended a procedure in the phase-in Hotelling T2 control chart although there is difficulty in interpreting the signals from multivariate control charts more work is needed on data reduction methods and graphics techniques. Basically, the multivariate control chart refers to the theory of prediction interval. Therefore, its called predictive multivariate control charts. We aim to construct what so-called predictive multivariate control chart both classical in this part in the phase-in Hotelling T2 and Copula-based ones. We argue that appropriate joint distribution function may be well estimated by employing Copula. A numerical analysis is carried out to illustrate that an Application Copula-based Multivariate control chart outperforms than bivariate control chart and others.

Abstract
There are many strategies that can be carried out by the company that will have implications / implications, which in general, namely the principal actors or network members in the chain of supply chains of red bricks that consist of five organizations or parties namely suppliers, manufacturers, distributors, retailers, and consumers. The five principal actors must be as a totality. Next The nature of competition between supply chain networks is then the phasing implications of the supply chain process where the evolutionary process requires phasing, so it needs to be detailed, differentiated, and planned about what, who, and how for each element such as drivers, focus, benefits, tools, areas of action, guidelines, models, alliances, and training, The key to supply chain management is network integration or management among all related companies, the company is still owned by the owner, and there are no acquisitions so that the strategies developed are total and collective, not the strategy of individual companies. All relevant parties need to be included in order to produce a plan believed and implemented together, which will then be carried out by several targets which are specific performance benchmarks, as well as improving customer relations. the SCOR model (Supply Chain Operations Reference) is used to issue performance measurement standards in the supply chain so that it can be used for comparison with other industries. In this research, it is expected to get a solution to declare the impact of the red brick supply chain seen in terms of total effort in improving and or creating competitive advantage (new) so that competition no longer occurs between companies, but between one supply chain and another supply chain , or between one company network and another company network.

Abstract
The research aims to examine factors that may cause inventory mismanagement in a Small Medium Enterprises (SME), which is a market leader in the Heavy Equipment after sales business, is selected. The company is selected because despite its status as market leader, the company deals with various inventory problems, for examples slow moving stocks, delivery delays to customers, etc. Those problems, at the end, may reduce companys profit. In order to determine the main causes, this study applies quantitative and qualitative methods. Quantitative method, specifically Pareto diagram and Inventory Turnover Ratio (ITR) is mainly used to evaluate sales and inventory management. ITR is affected by spare part quantity, warehouse area used, and the material amount. The top five ITR ratings are examined further through observation, interview, and questionnaire techniques. Meanwhile, the qualitative method is applied to evaluate the companys inventory information systems, procedures and coordinations among departments, and human resources. Our findings suggest that the unintegrated companys information system and lack of qualified human resources are the main factors affect inefficient inventory management. The research benefits to industry by suggesting the importance of information systems and human resources to inventory management. As for academics, this research enriches inventory management literature.

Abstract
Minimum mileage and maximization of utilities will help the product distribution process to be optimal. Soft drink companies in the city of Medan have problems in distributing products to consumers who are not on time. This is related to the lack of regulation of product distribution channels by the company. Therefore this research was conducted to optimize product distribution routes in order to minimize distribution costs. With the Traveling Salesman Problem (TSP) method, it will combine several closest distribution routes and improve the route sequence. Then the development of sub-routes that are formed from the travel time and utility of transportation equipment used. Formation of sub-routes is still done manually while increasing the order of sub-routes is done by using the Software Quant System (QS) version 3.0. and produce minimum mileage on each sub-route. 6 sub-routes are carried out in one week and are served by 1 transportation car with a capacity of 220 crates. The proposed sub-route is 171 km shorter than the available sub-routes, thus shortening the travel time by 302 minutes to transport the product and save transportation costs of Rp. 68800, - (per week).

Abstract
Distribution is an important aspect of the delivery process. So it is an activity that is useful to launch goods distribution activities from upstream to downstream. According to Philip Kotler (1997) Distribution is a group of organizations that create a process of distribution activities of a good or service, the distribution of trash from the Temporary Disposal Site (TPS) to the end in the optimal Final Disposal (TPA) is a step to Accelerate the arrival of trash to the final dump. presents an extension of the ant colony technique to solve the optimization case of the shortest route by taking into account the distance, capacity and grouping of the optimal depot using the ant algorithm model as the first step of optimization, The ant colony algorithm is adopted from the behavior of ant colonies known as the ant system (Dorigo, 1996 ). Naturally, ant colonies are able to find the shortest route on the way from the nest to the food sources Ant colonies can find the shortest route between the nest and the source, of food based on footprints on the trajectory that has been passed. This paper presents an extension of existing ant colony techniques to solve some of the trash removal problems from some Temporary Disposal Sites (TPS) to end up in the Final Disposal (TPA). so that in the process of taking garbage to each TPS, each vehicle brings waste with optimal capacity, without any empty vehicle, when the vehicle reaches the Final Disposal (TPA) with the shortest route consideration. Based on the results of simulation and evaluation studies using a model approach, it has been shown that the ant colony optimization technique proposed in this paper leads to more optimal results than the method.

Abstract
Product quality is one of the most important things in a product offered. Flat glass is one of the many products produced because of high consumer demand. This requires the company to run the production process well to produce products that meet consumer expectations. The purpose of this study was to determine the type and amount of waste in the glass-making production process and analyze the root causes of the glass-making process. The method used in this study is a mixed method, namely quantitative and qualitative approaches, which are directly measured using the Lean Manufacture concept approach. Lean manufacturing is a production activity that focuses on reducing waste in all aspects of the companys production activities. From the results of the study, it can be concluded that the cause of reject is influenced by two factors, namely humans and machines, human factors due to not running the standard operational procedure (SOP) properly, the factors of the machine due to not doing the appropriate machine settings at a particular station.

Abstract
The purpose of this study is to find production capacity and storage capacity of raw material warehouses in agriculture-based industries. It is a concern; the supply of raw materials can only be done during the harvest period while production must continue throughout the year. This case occurs in the coffee processing industry, where the supply of raw materials for the harvest period is from April to August while production must be carried out every day throughout the year. To model, the problem is used by simulation using deterministic variables. Various capacity scenarios are tested to see system performance. The results obtained show maximum production capacity is to follow working hours with a minimum raw material storage capacity&

Abstract
During processing and storaging of strawberry products like puree were often found some problems such as loss or change of red colour anthocyanin, formation of brown pigment and loss of ascorbic acid. The purpose of this research is to determined the best of precise dextrin concentration to stabilitation of red colour anthocyanin pigment and the quality during storage at temperature 10±2oC for 30 days. Rendomized block designed used with dextrin concentration as treatments that consists of three levels with four replications. The treatments are, dextrin concentration 0,8%, 1,6%, and 2,4%. The data were analyzed using of ANOVA and continoued by LSD analyzed if the treatment given significantly effect. To get the best treatment used of effectivity index value. The result showed that the treatment of dextrin 1,6% having the highest of total product value 2,27 and produced strawberry puree with the best quality during storage at temperature 10±2oC for 30 days. The characteristics of the strawberry puree are anthocyanin concentration 23,67 mg/kg, total ascorbic acid 78,12 mg/100g, total soluble solid 13,23%, moisture content 79,88%, pH 3,16, red colour intencity (a* value) +30,80, degree of lightness (L* value) 35,40, and total of microba 21,6 x 103 sel/g.

Abstract
Recently, the problem of minimizing carbon emissions in manufacturing has become a focus of much research. One of the efforts that were successfully carried out was managing the sustainable economics order quantity (SEOQ). However, several SEOQ had assumption such as (1) warehouse costs are ignored, (2) warehouse emissions are avoided, and (3) warehouse costs are ignored. In this paper, we developed the SEOQ model with warehouse costs and capacity limits. There are two proposed SOQ models. Model 1 was the SEOQ model with warehouse costs and carbon emissions. At Model SEOQ 2, this model considered warehouse costs, carbon emissions, and capacity. We also proposed procedures to minimize total inventory costs. Finally, a numerical experiment was conducted to test the model. Based on numerical experiments, the proposed model useful to solve SEOQ problems with warehouse costs and capacity limits.
