Sistem Pengendalian Persediaan Barang Berbasis Website dengan Metode Economic Order Quantity dan Reorder Point

Inventory of goods is one of the important factors in developing a business. This inventory affects operational costs. Excess inventory will also lead to greater storage and maintenance costs. Meanwhile, a lack of inventory will cause stock out. Website Inventory information system with the Economic Order Quantity (EOQ) and ReOrder Point (ROP) method can be an alternative to overcome this problem. This information system was developed using the SDLC (System Development Life Cycle) development method. The programming language used is PHP Hypertext Preprocessor, MySQL as database, and Xampp as a web server. EOQ method can determine the level of inventory required by the company. Meanwhile, the ROP to determine the time an item is in the warehouse must be added to the inventory before it runs out. This research results that the determination of the quantity of purchase inventory using the EOQ method and the ROP method is more efficient and the inventory becomes more optimal so that the store can get maximum profit. The results of the system functionality test show that this system works very well

An Empirical Analysis of Software Fault Proneness Using Factor Analysis with Regression

During the early stages of the life cycle development process for software, the developer mainly makes use of the fault prediction process for the development of different modules. These modules help in detecting faulty modules and classes. Further, this process also helps in determining the modules which require a high level of refactoring during the maintenance stage. The objective of this research is to classify faults and to explore the usability of Factor Analysis with Regression (FAWR) which drastically ameliorate the system performance. A review of recent studies performed that uses the different fault prediction techniques. To direct this research, two research questions (RQ) are defined, one related to the integration of techniques to enhance the development of fault prediction model, and another is to check the technique to overcome the limitations of old methods. To answer these RQs, FAWR techniques are used for predicting faults. To assess the quality of the technique, two experiments were conducted. Results show that FAWR is the better performing method among the two prediction methods investigated. The results proved that the prediction capability of FAWR technique is significantly better. Factorization method is able to classify a module whether it is fault-prone or not. The constructed models use to estimate the proneness of faults surpass the standard regression models. The system evaluations indicate that the reduction of terms results in the betterment of outcomes. Moreover, the consideration of FAWR is a significant technique for the prediction of faults in software.

New Perkinsea Parasitoids of Dinoflagellates Distantly Related to Parviluciferaceae Members

Perkinsea is a phylogenetic group of protists that includes parasites of distantly related hosts. However, its diversity is still mainly composed of environmental sequences, mostly obtained from freshwater environments. Efforts to isolate and culture parasitoids of dinoflagellates have led to the description of several phylogenetically closely related species constituting the Parviluciferaceae family. In this study, two new parasitoid species infecting dinoflagellates during recurrent coastal blooms are reported. Using the ribosomal RNA (rRNA) gene phylogenies, we show that both cluster within Perkinsea, one of them at the base of Parviluciferaceae and the other in a distinct branch unrelated to other described species. The establishment of host-parasite lab cultures of the latter allowed its morphological characterization, resulting in the formal description of Maranthos nigrum gen. nov., sp. nov. The life-cycle development of the two parasitoids is generally the same as that of other members of the Parviluciferaceae family but they differ in the features of the trophont and sporont stages, including the arrangement of zoospores during the mature sporangium stage and the lack of specialized structures that release the zoospores into the environment. Laboratory cross-infection experiments showed that the parasitoid host range is restricted to dinoflagellates, although it extends across several different genera. The maximum prevalence reached in the tested host populations was lower than in other Parviluciferaceae members. The findings from this study suggest that Perkinsea representatives infecting dinoflagellates are more widespread than previously thought.
