Sistem informasi pemesanan produk dan outlet yang berjalan saat ini di PT. Prima Lakto Sehat masih menggunakan proses bisnis yang konvensional, dimana setiap adanya pendaftaran outlet baru harus dilakukan pendataan secara manual sehingga membutuhkan proses panjang yang mengakibatkan terjadinya penumpukan data yang mengakibatkan meningkatnya kesalahan pencatatan data sampai hilangnya data transaksi pemesanan outlet oleh pihak toko yang ingin bergabung. Demikian juga dengan proses pemesanan produk yang dilakukan oleh setiap outlet ke pihak perusahaan, proses yang dilakukan saat ini belum menggunakan suatu sistem yang terintegrasi sehingga setiap pemesanan produk yang diterima oleh perusahaan belum tercatat dengan baik.  Melihat permasalahan tersebut, sistem informasi pemesanan produk dan outlet dengan menggunakan layanan website menjadi suatu solusi yang dipilih oleh PT. Prima Lakto Sehat. Disamping kemudahan dalam proses transaksi pemesanan produk oleh setiap outlet dan pembukaan outlet yang baru, sistem informasi yang dibangun diharapkan mampu membantu PT. Prima Lakto Sehat dalam mengelola data transaksi keduanya secara cepat dan tepat sehingga memudahkan pihak manajemen perusahaan dalam menentukan suatu pengambilan keputusan. Sistem informasi pemesanan produk dan outlet berbasis web ini dibangun dengan dengan Model Waterfall menggunakan bahasa pemograman PHP dan database MySQL. Dengan adanya sistem informasi pemesanan ini, diharapkan salah satu proses bisnis yang ada di PT. Prima Lakto Sehat menjadi semakin efektif dan efisien Kata kunci: Model Waterfall, Sistem Informasi, Pemesanan, PHP, MySQL Abstract: The current development of information technology provides opportunities for every company to have business competitiveness, so that companies are required to have an information system capable of supporting management in increasing company productivity. Information system for ordering products and outlets currently running at PT. Prima Lakto Sehat still uses conventional business processes, where each new outlet registration must be done manually so that it requires a long process which results in data accumulation resulting in increased data recording errors and loss of outlet order transaction data by the shop that wants to join. Likewise with the product ordering process carried out by each outlet to the company, the process currently carried out does not use an integrated system so that every product order received by the company has not been recorded properly. Seeing these problems, the information system for ordering products and outlets using website services is a solution chosen by PT. Prima Lakto Sehat. In addition to the convenience in the product order transaction process by each outlet and the opening of new outlets, the information system built is expected to be able to help PT. Prima Lakto Sehat in managing both transaction data quickly and precisely, making it easier for company management to make decisions. This web-based product and outlet ordering information system was built with the Waterfall Model using the PHP programming language and MySQL database. With this ordering information system, it is hoped that one of the existing business processes at PT. Prima Lakto Sehat is becoming more effective and efficient.

Abstract— Natural disasters are disasters caused by natural events and cannot be avoided including earthquakes, tsunamis, volcanic eruptions, floods, hurricanes, droughts, and landslides. One of the natural disasters that often occurs in Indonesia is a landslide disaster. One of the regencies in West Java Province that had experienced a landslide was a Purwakarta district area. Landslide is one type of mass or rock mass movement, or a mixture of both, down or out of the slope due to the disruption of the stability of the soil or rocks making up the slope. With a data mining approach that uses the decision tree method or C4.5 Algorithm, a classification model will be made where the model functions as a classification of the causes of landslides in Purwakarta district.

Kurangnya inovasi dan variasi seorang guru dalam menyampaikan materi seringkali membuat siswa kurang tertarik atau bersemangat dalam mengikuti materi pelajaran. Metode pembelajaran yang berupa materi yang hanya dijelaskan secara langsung pun dapat menurunkan minat siswa, kurang efektif dan efisien. Oleh karena itu dibuatlah sistem pendukung keputusan dengan menggunakan metode Analytical Hierarchy Process (AHP) untuk menentukan metode pembelajaran yang lebih efektif dipergunakan yang mampu menjangkau siswa dalam menyerap materi dan ilmu yang disampaikan dengan baik. Ketentuan kriteria dalam pemilihan metode pembelajaran yang digunakan adalah hasil diskusi d engan pihak terkait langsung. Kriteria yang ditentukan ada empat kriteria, yaitu keefektifan penggunaan, pemahaman siswa, kemampuan siswa, dan peminatan siswa. Hasil keputusan dari perhitungan penggabungan pendapat responden menggunakan Microsoft Excel dan aplikasi Expert Choice menunjukkan metode pemecahan masalah sebagai peringkat pertama dengan bobot nilai 0,473 dilanjutkan metode penugasan dengan bobot 0,267 dan metode pemberian informasi dengan bobot nilai 0,260.

Data storage on server laboratory at the computer science when needed.It was because application that progressively and document required was handled by more than one person.Currently there are 6 class space the laboratory contained 30 units of computer in each room. All the time, Laboran (person who manage and work in a laboratory) have to bring harddrive external if you want to install application needed for each the lab, but during this laboran has only two external hard drive. This condition resulted in the process of installation application in the laboratory require a long time. In addition, every month laboran have to make recapitulation contract for 22 person laboratory’s assistant. Now, to make contract assistant in the lab, laboran have to open one of the workstations that is in the fasilkom’s laboratory. This can slow performance, because laboran have to coming into the fasilkom’s laboratory.  By the presence of the problems mentioned above, then built a file sharing that is used to hold the application of which is required in the entire room of Fasilkom’s laboratory. In addition, a file sharing this can be used to speed up the emoluments of the preparation of reports on the whole lab assistant that until now had been stored luminance space laboratory so that laboran no need to use more external hard disk in installation perform the process of application by opening the Samba through Windows Server Explorer. It is also the case to compile the report honorarium of the lab’s assistant, laboran enough to use of a file sharing fastly. A file sharing development is using the Linux Ubuntu operating system Version 12.04 and the application of the Samba Servers the Samba to connect storage a file that is in linux so that it can be opened in a windows or linux operating system based. Keywords : File Sharing Server, Samba Server, Linux Ubuntu, Computer Lab.

Nowadays, vehicle rental has become a common function for companies that have busy operational activities. Every company in carrying out operational activities requires a vehicle that is always there when needed. PT. Agung Solusi Trans is a vehicle rental company that rents various vehicle brands commonly used by customers to rent vehicles. In addition, PT. Agung Solusi Trans is also difficult to get updated information regarding the level of sales per period. Therefore, we need a decision support system and a method that can be used to design a business strategy that can provide an efficient and effective information, namely data mining using the a priori algorithm association method. The researcher specializes in taking only vehicle types as research material by selecting fifteen brands, including Agya, Yaris, Sienta, Calya, Avanza, Innova, Rush, Vios, Altis, Camry, Fortuner, Alphard, Hi Ace, Voxy, and Hilux. In analyzing the data, the writer uses a priori algorithm calculation by testing the hypothesis of two variables between the value of support and the value of confidence. After that, apriori algorithm is calculated using Tanagra. Based on the analysis done by the author, that the brands most sought after by customers are Calya, Avanza, Hilux. From these results can be used by PT. Agung Solusi Trans to prepare vehicle brands that are widely leased by customers and increase brand inventory.
