Review Model

The development of information technology has become a necessity for every company, one of which is the optimization of inventory planning. The joint warehouse owned by the Chickenpedia Restaurant which has to supply various types of raw materials to the three restaurant branches often experiences stock outs and has to make emergency orders resulting in losses. For this reason, it is necessary to control the inventory of raw materials in the shared warehouse so that stock outs can be overcome and losses that arise can be minimized. One of them is by using the Continuous Review method. By using this method, the optimal order quantity and reorder point will be obtained. The weakness is iterative calculation and monitoring of raw material stock manually. For this reason, it is necessary to support an information system to speed up and make it easier to calculate when to place an order and how many orders of raw materials to suppliers so as to reduce the occurrence of running out of raw materials. The Information System can also monitor the stock of raw materials every day in real time based on the number of incoming and outgoing goods that enter the application.

This chapter presents a case study of Isobord1, a Canadian manufacturer of high quality particleboard that uses straw instead of wood as the main raw material input. Isobord is facing critical operational problems that threaten its future. Gary Schmeichel, a biotechnology consultant hired by Isobord, must recommend how much straw collection equipment to purchase and what kind of information technology to acquire to help manage equipment dispatch operations. Schmeichel is exploring how geographic information systems (GIS) and relational database management systems (RDBMS) might help manage operations, but budget and time constraints and organizational inexperience seriously threaten these efforts. Decisions must be made immediately if there is to be any hope of implementing a system to manage the first year’s straw harvest. Readers are challenged to put themselves in Schmeichel’s shoes and prepare recommendations for Isobord.

Geological Phenomenon

In geochemical prospecting for gold a major difficulty is that many values are below the chemical detection limit. Tracers for gold thus play an important role in the evaluation of multivariate geochemical data. In this case study we apply geostatistical methods presented in Wackernagel (1988) to multielement exploration data from a prospect near Limoges, France. The analysis relies upon a metallogenetic model by Bonnemaison and Marcoux (1987, 1990) describing auriferous mineralization in shear zones of the Limousin. The aim of geochemical exploration is to find deposits of raw materials. What is a deposit? It is a geological anomaly which has a significant average content of a given raw material and enough spatial extension to have economic value. The geological body denned by an anomaly is generally buried at a specific depth and may be detectable at the surface through indices. These indices, which we shall call superficial anomalies, are disposed in three manners: at isolated locations, along faults, and as dispersion halos. These two definitions of the word "anomaly" correspond to a vision of the geological phenomenon in its full continuity. Yet in exploration geochemistry only a discrete perception of the phenomenon is possible through samples taken along a regularly meshed grid. A superficial anomaly thus can be apprehended by one or several samples or it can escape the grip of the geochemist when it is located between the nodes of the mesh. A geochemical anomaly, in the strict sense, only exists at the nodes of the sampling grid and we shall distinguish between: a pointwise anomaly defined on a single sample, and a groupwise anomaly defined on several neighboring samples. This distinction is important both upstream, for the geological interpretation of geochemical measurements, and downstream, at the level of geostatistical manipulation of the data. It will condition an exploration strategy on the basis of the data representations used in this case study. A pointwise anomaly, i.e., a high, isolated value of the material being sought, will correspond either to a geological phenomenon of limited extent or to a well hidden deposit.

ABSTRACT        The production of pig manure waste potentially pollutes the soil, water and air. One of the most effective processing a waste treatments is through composting. The composting process takes a long time if not assisted by the activator as decomposers of organic materials in order to accelerate the composting process. Activators such as local microorganism (MOL) contain macro nutrients, micro and active microorganism that potentially decomposed organic materials, growth stimulants and pest/disease control agents such as to help speed up the composting process. This study aims to determine the C/N ratio of optimal raw materials for composting of pig manure and vegetable waste, determining the effect of adding local microorganism (MOL) to the length of time of composting and determining the effectiveness of business from composting of pig manure and vegetable waste based on the calculation of B/C ratio.        This research uses quantitative approach with experiment method. The first stage is the preparation of the raw material which is divided into three groups : composition 1 with 75% (pig manure) and 25% (vegetable waste), composition 2 with 50% (pig manure) and 50% (vegetable waste) and then composition 3 with 25% (pig manure) and 75% (vegetable waste). Furthermore, the best raw material composition was treated with variations of MOL addition of A (100 ml), B (300 ml), C (500 ml) and D (without MOL).        The results showed that the composition of the best raw material mixture was a mixture composition of 25% (pig manure) and 75% (vegetable waste) with a C/N ratio of 38.95. The effect of MOL addition indicates that the greater MOL volume the faster to composting process. The quality compost with addition of MOL has C/N ratio levels is (16,30), N-total (1,65%), P tersedia (8043,02 ppm), K tersedia (8857,40 ppm), Fe (1,87%), Mn (0,09%) Zn (480 ppm) in which that value meets the SNI 19-7030-2004. Based on analysis of B/C ratio obtained result of 1.04 where the value is approaching criteria B/C ratio more than 1.00 which means compost business feasible to be developed.   Keywords : Pig manure, MOL, time of composting, composter, B/C ratio

Urbanization is a global trend: Since 2007 more than 50% of the world’s population have been living in urban areas, and rates of urbanization are continuing to rise everywhere. This growth in urbanization has led to an increased demand for natural resources, in particular non-metallic minerals such as stones, sand and clay, which account for one third of the entire flow of materials. Generally, these materials are traded within regional markets. This close geographical link between the demand for building materials in urban areas and the material supply in the hinterland leads to massive interventions in the natural environment and landscape. These urban–rural linkages can be revealed by applying Material Flow Analysis (MFA) to the built environment in order to trace the flows of building materials. The objective of this paper is to present a method for quantifying regional material flows by considering the supply and demand of building materials. This will be applied to the Vietnamese case study area of Hanoi and its hinterland province Hoa Binh. The results indicate a consumption of almost 60% of the construction mineral reserves in total secured by planning in the hinterland province considering a period of 15 years. However, this does not allow for the general conclusion that raw materials are sufficiently available. The sand reservoirs are only sufficient for eight years and clay reserves are used up after four years. This increases the need to exploit further raw material reserves, which are becoming increasingly scarce and results in stronger interventions in nature In order to safeguard the hinterland from the negative impacts of urbanization, a new understanding of resource efficiency is needed—one that acknowledges both resource efficiency in the construction of urban structures and appropriate resource conservation in the provision of the raw materials from the hinterland. This will require the creation of new integrated planning approaches between urban and regional planning authorities. Regional MFA is one way of realising such an approach.

The Right

The right strategy in inventory is the main point in maintaining adequate and guaranteed supply continuity. Inventory strategies are becoming important but complex when the number of items that must be prepared is increasing. In this regard, it is necessary to analyze the product groupings in several classifications. Prioritized products receive special attention.The same problem is faced by PT PEKA, an import raw material distribution company that has nearly 2000 product items. Based on data demand is known, that the company's demand does not have a fixed pattern. Many products have regular and irregular demand, even the number of regular demand is very volatile. Companies often experience excess stock or vice versa due to lack of stock demand according to predictions, long lead times and product self-life that varies. Related to this, alternative product groupings or classifications are needed in accordance with company conditions. The company currently has frozen and unfrozen products, has items made from natural and non-natural raw materials and has a short and relatively long lead time.PT. PEKA groups products in various stages, which lead to a combination of ABC and XYZ classifications. Demand of priority items generated from the grouping is then forecast according to the model that gives the smallest MSE / MAD. Furthermore, a case study was carried out to calculate the Total Relevance Cost (TRC) from the calculation results to be compared with the real TRC. TRC according to the classification results was Rp. 1,293,370,148, - lower than the actual condition TRC, which amounted to Rp. 1,805,887,874, -

The Tengku Diujung restaurant is one of the tourist destinations that is frequently visited by tourists because the restaurant has a mainstay menu that is in demand by many visitors, one of which is lobster noodles. However, each sales report still records data manually, sometimes experiencing errors due to inaccuracies in recording data. The formulations in this study are; how to manage all data on reports of receipts, orders, and sales or expenditures of goods, and whether employees are easy to find data, and how to manage data on receipts, orders, and sales or expenditures of goods. To complete the data needed in the preparation of this study, the authors use writing sources, namely; Library Research, Field Research, and Interviews and Observatories. From the results of the discussion on "Inventory Information System at the Tengku Diujung Restaurant (Simeulue Regency)" the author can conclude that the use of a manual system has limitations in selling goods. This information system, makes it easier for the restaurant to present information about revenue, ordering, and sales data to its customers. Although it requires a lot of money, it is worth the ease with which it is obtained, and designing this application will speed up the production of receipts, orders, and sales reports. The results of this study are the development of an Inventory Information System application with 9 (nine) inputs in the form of; data on goods, suppliers, customers, receipts, expenses, stocks, transactions, and application users. There are 6 (six) output designs consisting of; goods data, suppliers, customers, receipts, expenses, and stock reports.

Raw material inventory control is used to place orders and ensure that shrimp raw materials arrive in a timely manner in accordance with consumer demand. This will expedite the course of the production process. This research was conducted at PT. Grahamakmur Ciptapratama Sidoarjo with the aim of knowing and analyzing the control of raw red ginger in frozen shrimp products. The method used is the Economic Order Quantity (EOQ) Method with the Lot For Lot (LFL) Technique. In addition, safety stock analysis, Maximum Inventory, warehouse capacity and Reorder Point analysis were carried out. The results of the study showed that inventory costs using the EOQ technique were lower than the company method or using the LFL technique. The EOQ technique produces an inventory cost of IDR 292,591.00 in 2017 with an order frequency of 105 times and in 2018 of IDR 289,750.00 with a booking frequency of 116 times. In the LFL technique inventory costs are more expensive, but the planning technique in the LFL method can be applied by companies in anticipation of raw material inventory if there is a small inventory. If the company applies the EOQ method, the company purchases raw materials in a larger amount, but the warehouse capacity in the company can still be met, this can be seen from the calculation of Maximum Inventory and warehouse capacity.
