<![CDATA[Operasi pengamanan perbatasan wilayah laut RI-Malaysia/Ambalat adalah operasi yang dilaksanakan oleh TNI AL sepanjang tahun dalam rangka menegakkan hukum dan menjaga kedaulatan NKRI di perbatasan wilayah laut RI-Malaysia/Ambalat sesuai dengan ketentuan hukum nasional dan hukum internasional yang berlaku. Pada kenyataannya masih sering terjadi gangguan keamanan dan pelanggaran batas wilayah terutama yang berasal dari pihak negara Malaysia. Oleh sebab itu maka seluruh KRI dan Pesud Patmar yang terlibat dalam operasi pengamanan perbatasan wilayah laut RI-Malaysia/Ambalat dituntut kesiapannya untuk dapat hadir setiap saat dalam rangka menegakkan hukum di laut sekaligus menampilkan dampak strategi penangkalan.Akan tetapi masih ada beberapa masalah yang timbul karena ternyata KRI yang terlibat di dalam operasi pengamanan perbatasan wilayah laut RI-Malaysia/Ambalat tidak selalu dapat hadir tepat pada waktunya dalam menangani setiap kejadian pelanggaran yang ada. Hal ini mengakibatkan keterlambatan penanganan ataupun banyaknya pelaku pelanggaran yang berhasil lolos dari penindakan KRI. Dari permasalahan yang ada maka melalui pendekatan metode simulasi akan dihitung waktu respon KRI terhadap setiap kejadian pelanggaran di perbatasan wilayah laut RI-Malaysia/Ambalat.Penelitian ini bertujuan untuk membuat sebuah model simulasi ke dalam suatu sistem komputer guna meningkatkan waktu respon KRI terhadap setiap kejadian pelanggaran di perbatasan wilayah laut RI-Malaysia/Ambalat. Dalam rangka meningkatkan waktu respon KRI tersebut maka dibuatlah beberapa skenario perubahan untuk membandingkan hasilnya dengan kondisi eksisting. Dari hasil percobaan simulasi yang dilakukan ternyata didapatkan hasil skenario memiliki rata-rata waktu respon yang lebih baik (lebih cepat) daripada kondisi eksisting yang ada. Hal ini dapat digunakan untuk membantu proses pengambilan keputusan yang akan dilakukan oleh para Pimpinan TNI AL.]]>

<![CDATA[The scheduling of production floor is a sophisticated problem which seeks the optimal task allocation to certain resources under a number of constraints. The use of optimization techniques facilitates the determination of acceptable solutions that considered optimized for a specific problem. This paper proposes production scheduling solution based on job priority in a Non-Deterministic Polynomial-time hard (NP-hard) problem. The case study was taken from the Spirit Aerosystem Project, particularly in the Inboard Outer Fixed Leading Egde - Drive Rib 1 component production process. The problem consists of finding the machine operations schedule, taking into account the precedence constraints. The main objective is to minimize total delays or tardiness. The genetic algorithm was employed to determine the optimized production scheduling solution. The parameter for genetic operators in this study consists of a roulette wheel selection, 1 elitist chromosome, partially-mapped crossover mutation and 1 point mutation. The termination condition was achieved when there has been no improvement in the population for 30 iterations.The results show that the algorithm is capable to generate optimum production schedule with minimum tardiness for the given problem. Keywords: Genetic algorithm, job shop problem, scheduling problem]]>

<![CDATA[Senjata Penangkis Serangan Udara (PSU) milik KRI di jajaran TNI AL saat ini sebagian besar sudah ketinggalan teknologi salah satunya adalah PSU 20 mm Meriam Rheinmetall pada KRI Landing Platform Dock (LPD) kelas KRI Makassar, sehingga tidak bisa menjamin pelaksanaan tugas pokok. Oleh karena itu diperlukan suatu langkah strategis dalam upaya mencapai kesiapan kapal kelas KRI (Kapal Perang Republik Indonesia) Makassar ini secara optimal.Langkah-langkah yang dapat dilakukan antara lain modernisasi dan pembelian sistem senjata baru yang mengacu pada kekuatan pokok minimum (Minimum Essential Force / MEF) TNI AL. Berdasarkan rencana pembelian senjata ini untuk mengganti sistem senjata yang sudah tua, maka yang dipilih adalah Senjata penangkis serangan udara dengan klasifikasi daya hancur dan perkenaan yang akurat.Penentuan Prioritas pemilihan senjata dipengaruhi oleh banyak faktor, baik yang bersifat kualitatif maupun kuantitatif. Salah satu teknik pengambilan keputusan adalah dengan pendekatan metode Fuzzy Multi Criteria Decision Making (MCDM) yang dianggap sangat tepat untuk permasalahan bobot kriteria yang bersifat fuzzy (kabur). Metode fuzzy MCDM sebagai model yang diterapkan guna memperoleh nilai prioritas dalam perancangan sistem pendukung keputusan untuk menentukan alternatif senjata penangkis serangan udara untuk LPD kelas KRI Makassar. Selain itu metode fuzzy MCDM akan mengatasi masalah multikriteria pada proses penentuan penentuan senjata ini serta mengatasi kemungkinan adanya data-data yang bersifat ketidakpastian.Berdasarkan pengolahan data, didapat senjata terpilih yaitu NG-18 6-Barreled 30MM Naval Gun, karena senjata ini mempunyai beberapa keunggulan antara lain daya hancur yang sangat tinggi, hubungan diplomatis dengan negara pembuat berlangsung baik sehingga tidak dikhawatirkan untuk mengembargo senjata ini suatu saat nanti, dibandingkan senjata lainnya dengan kemampuan taktis dan teknis senjata yang baik.]]>

<![CDATA[Navy as a marine core in the defense force is responsible for providing security for realizing stability and security of the country. At any time there was an invasion of other countries past through sea, TNI AL must be able to break the enemy resistance line through a sea operation to obtain the sea superiority. But this time the endurance of Striking force Unit at only 7-10 days and required replenishment at sea to maximize the presence in the theater of operations to meet a demand of the logistics: HSD, Freshwater, Lubricating Oil, foodstuffs and amonisi. For the optimal replenishment at sea required scheduling model supporting unit to get the minimum time striking force unit was on node rendezvous. Replenishment at sea scheduling model for striking force unit refers to the problems Vehicle routing problem with time windows using Genetic Algorithms. These wheelbase used is roulette for reproduction, crossover, and mutation of genes. Genetic algorithms have obtained optimum results in the shortest route provisioning scenario uses one supporting unit with a total time of 6.89 days. In scenario two supporting unit with minimal time is 4.97 days. In the scenario, the changing of the node replenishment Genetic Algorithm also get optimal time is 4.97 days with two supporting units. Research continued by changing the parameters of the population, the probability of crossover and mutation that can affect the performance of the genetic algorithm to obtain the solution. Keywords: Genetic Algorithm, Model Scheduling, Striking Force unit]]>

<![CDATA[The workload of an organization is related to the efficient and effective utilization of human resources so that it can realize the vision, mission and objectives of the organization. Various methods are used to optimize the number of personnel in an organization, so that each task can be completed effectively and efficiently. KRI Diponegoro-365 personnel as the TNI Maritime Task Force, the Garuda Contingent can not be separated from the problems regarding the lack of conformity to workload with the allocation of the number of available personnel. To overcome this, an analysis of workload measurement is needed which can then be used for determine the allocation of the right number of personnel needed in each division. This study uses the measurement of NASA-TLX mental workload and physical workload according to TNI Roles. Both of these methods are then compared between mental and physical burden that occurs. From the results of the comparison, it was found that physical workload is needed in the completion of tasks in each division. After a comparison, then the determination of the allocation of the number of personnel will be carried out using the physical workload approach based on the description of the tasks in each division. The results of the calculation will then show the division that has excess or lack of personnel. The overall results obtained from this study can be concluded that the number of maritime task force personnel using the Diponegoro class KRI is appropriate, but the allocation of personnel in each division needs to adjust to the existing workload. Keywords: Workload, NASA-TLX (Task Load Index), Number of Military Personnel]]>

<![CDATA[Faced with conditions of life of the nation that continues to evolve into a multidimensional cover all areas of the life of the nation, then certainly required the development and deployment of the total potential and power of the nation effectively. Therefore it is the power that was developed to deal with these threats must also have the ability to multi-dimensional as well. Reality is always pushing to restructure the military concept of defense to become responsive and adaptable and tailored to the substance of the reforms in the defense. The main problem faced by Indonesia to develop a domestic defense industry is the inability of industry and education sectors to absorb the fundamental aspects of the Revolution in Military Affairs (RMA). This inability does not allow Indonesia to experience significant breakthroughs in the application of RMA. So with reference to the condition necessary to anticipate concrete steps in developing a systematic plan to build the defense industries are able to anticipate the revolution in military affairs. Among priorities at once by selecting the appropriate stages of the development plan which includes the development of Main Equipment Weapon System, Spatial Planning Area Defense, Civil Defense Development, and Spatial Structure of the Organization. And one of its efforts is the creation of the ability of military logistics support system effective and efficient and responsive, which in this case is the development of Arsenal's arsenal of weapons and ammunition in terms of both quality and quantity so that is always ready to face any condition of any contingency that would happen. Determining policy location Arsenal first location contains more choices in environmental issues multi-objective and multicriteria decision, then the model is proposed to be the appropriate methodology to accommodate the qualitative preference and priority-setting objectives/criteria for future development is to approach the Analytical Hierarchy Process (AHP). Principle of the AHP method is to break breaking a complex situation and unstructured, into its component parts, arranging these variables in a section or an order of hierarchy, giving numerical values to subjective considerations about the relative importance of each variable and analysis various considerations is to determine which variables have the highest priority and act to influence the outcome of the situation. From the results of the solution by using the AHP method showed that the first priority location determination Arsenal 1 in the eastern region is a factor analysis of logistics operations to support operations capabilities in the integrated logistics support system that effectively and efficiently. And the locations selected for Arsenal's first priority location is in the eastern region Lantamal Ambon.]]>

<![CDATA[PT. X is a newspaper publishing company. In publishing newspapers, paper raw materials are needed as the main ingredient. In choosing a supplier of paper suppliers, so far the company still applies conventional methods. Improper supplier selection process will have an impact on the sales of the company because it relates to the production process and also the products to be sold later. Many things must be considered in choosing suppliers. In the decision-making process for selecting suppliers, it must be noted that the factors (criteria) that each other might be interrelated. The Analytic Network Process (ANP) method is a method of decision making with many interrelated criteria. This problem is represented in a system with dependence and feedback. The linkages found in the ANP method are linkages in a set of elements (node comparison) and linkages to different elements (cluster comparison). The use of the ANP method will produce priority value weights on all elements contained in the decision making system. From the research that has been done at PT. X there are 4 consideration criteria consisting of 12 sub-criteria, and 3 alternative choices. Based on the results of data processing, alternative suppliers of CV. A was chosen as the best alternative supplier with the highest weight value of 0.158 then CV. B with 0.145 and CV. C of 0.134. Therefore, alternative suppliers of CV. A is the best alternative supplier for the company.]]>

<![CDATA[Konsep umum operasi keamanan laut adalah operasi kehadiran sehari-hari dilaut dilaksanakan oleh kapal dan pesawat udara patroli maritim TNI AL. Pola patroli maritim yang digunakan saat ini KRI sebagai unsur utama. KRI akan melaksanakan patroli pada sektor yang telah ditentukan secara acak. Pola tersebut mempunyai banyak tantangan, yaitu perencanaan operasi yang kurang baik dan membutuhkan anggaran operasional cukup besar, jumlah KRI dan anggaran yang tersedia terbatas, serta kecepatan gerak menuju sasaran. Pusat Penerbangan TNI AL (Puspenerbal) memiliki Pesawat Patroli Maritim yang belum dimanfaatkan secara optimal. Pengamatan yang luas dan cepat merupakan keuntungan pengawasan menggunakan pesawat. KRI yang berpatroli pada daerah tersebut bisa menghemat bahan bakarnya dengan menunggu informasi dari pantauan udara oleh pesawat patroli, sehingga dapat menghemat biaya operasional. Dalam tulisan dilakukan optimasi penugasan Pesawat Patroli Maritim berdasarkan coverage dan biaya operasi pada kondisi radar ideal dan riil dengan menggunakan metode Goal Programming dan Fuzzy Inference System (FIS). Hasil optimasi menunjukkan total maksimum Coverage Area yang diamankan oleh Pesawat Patroli Maritim pada kondisi ideal sebesar 87,0% sedangkan pada kondisi riil sebesar 66,98%. Kecilnya Coverage Area disebabkan oleh berkurangnya kemampuan Coverage Radar pada kondisi Riil. Penghitungan Fuzzy Logic Mamdani memungkinkan kita untuk memprediksi biaya operasional yang harus dikeluarkan apabila menghendaki Coverage Area dengan luasan tertentu.]]>
