Indonesia merupakan negara kepulauan dan memiliki sumber daya alam yang beragam yang dapat dikembangkan dan mampu meningkatkan sumber devisa dan perekonomian negara. Potensi ala mini kerapkali ditemui di daerah pedesaan yang identik dengan anggapan terbelakang. Salah satu lokasi desa yang dapat dikembangkan dan belum banyak mendapat perhatian adalah Desa Beteng Kabupaten Kulon Progo. Petatas dan ternak kelinci menjadi sebuah potensi yang dapat dikembangkan dan menjadi peluang usaha bagi warga desa sekitar. Tim pengabdian pun berinisiatif untuk memberikan sosialisasi/penyuluhan terkait bagaimana memanfaatkan petatas menjadi bahan baku brownies dan mengembangkan usaha ternak kelinci. Dua hal tersebut bertujuan untuk membuka wawasan warga desa agar dijadikan alternatif mata pencaharian untuk meningkatkan perekonomian mereka. Tim pengabdian melakukan pengidentifikasian potensi desa, studi literatur, pengumpulan data, dan penentuan solusi. Berdasarkan langkah-langkah tersebut, sosialisasi pun dilakukan dan didapati bahwa mayoritas warga belum sadar akan potensi usaha emanation petatas menjadi brownies dan ternak kelinci dapat dijadikan sumber pemasukan mereka. Warga Desa Beteng pun tampak antusias dan beberapa warga yang sudah mulai merintis usaha ternak kelinci menjadi sumber inspirasi warga lain. Begitupula dengan pembuatan brownies dari petatas, para ibu Desa Beteng dengan serius dan aktif dalam mengikuti sosialisasi ini. Monitoring terkait dua hal ini ke depan perlu dilakukan.

A leadership characteristic is a valuable quality in a leader, where this leader attitude can be seen as an example by the leader’s friends and colleagues. So, it is important to understand and learn someone’s leadership. On the contrary, it is also important for a leader to analyse his/her leadership for his/her own good. The ability to lead or leadership is based on someone’s behaviour, personality, capability, effort and also that person’s willingness to improve himself/herself. Leadership is science which its implementation should be determine based on the situation, environment and most importantly is the co-worker/colleagues. The most suitable leadership on board of a ship is an authoritarian but democratic leadership. It means all the instruction should be follow by all crews ship from Master to Ratings.Keywords: Master, Roles, Performance, Crews ship Sifat kepemimpinan merupakan kwalitas pribadi seseorang yang amat berharga bagi seorang pemimpin dalam menjalankan kepemimpinannya dan merupakan sikap dan tingkah laku yang dapat dilihat dan dicontoh oleh Iingkungannya.

Dynamic position on board of a ship is a system which controlled by a computer that automatically determine ship’s position using the mechanism of propeller, thruster and position center combined with angina and motion sensor that than give those information to the computer. The result will not only show the ship’s position but also the weather that influence it. In operating the Dynamic Positioning System, a master helped by a deck officer who had Dynٰamic Positioning or Dynamic Positioning operator certificate. Only a Dynamic Positioning Operator that operated the Dynamic Positioning equipment. To become a Dynamic Positioning Operator, she/he had to gone through Dynamic Positioning Basic or introduction course and Dynamic Positioning Advance or simulator course. All the required documents for Dynamic Positioning Operator called Dynamic Positioning log. After all the requirements are fulfill the Dynamic Positioning log is sent to London to be processed and registered for the Dynamic Positioning Operator certification. The role of a Dynamic Positioning Operator is very important in operating the Dynamic Positioning System as well as the maintenance the availability of the spare part on board of the vessel. Based on the report, most vessels’ accidents were because of human factor or human error. This become a prove that in order to smoothen work on board of vessel is not only about the condition of the vessel but also the conditional of the equipment, officers/ crews on board, work etiquette also if it is being reversed, it will increase the accident risk. Because working on board of a vessel, especially rig’s supply vessels are hard work as well as challenging, high risk also dangerous. But as long as we stick to the standard operational procedures all will end well.Keywords: Dynamic Positioning Operator, Dynamic Positioning System, Offshore Survey VesselsDynamic Position (DP) pada sebuah kapal adalah merupakan sistem pengendalian komputer yang dapat mengatur posisi kapal secara otomatis dengan menggunakan mekanisme baling-baling, thruster, sensor posisi yang dikombinasikan dengan sensor angina dan sensor gerak yang memberikan informasi pada komputer yang berhubungan langsung dengan posisi kapal dan keadaan cuaca yang mempengaruhinya. Untuk pengoperasian DP Sistem tersebut, nakhoda dibantu oleh perwira kapal yang telah memiliki sertifikat DP atau DPO. Setiap pengoperasian DP system, tidak terlepas dari peran DP Operator (DPO) karena hanya DPO yang berhak dan berkewajiban mengoperasikan Peralatan DP tersebut. Untuk bisa menjadi seorang DPO, harus mengikuti proses pelatihan yaitu DP Basic atau Induction Course dan DP Advance atau Simulator Course, setelah semua persyaratan dilengkapi, buku DP atau DP Log tersebut di kirimkan ke Nautical Institute di London untuk di proses dan di daftarkan untuk mendapatkan pengukuhan sertifikat sebagai DPO. Peran DPO terhadap pengoperasian peralatan Dynamic Positioning System sangat penting seperti halnya perawatan dan tersedianya suku cadang di atas kapal. Berdasarkan hasil laporan diketahui bahwa jumlah terbesar penyebab terjadinya kecelakaan di laut adalah karena faktor manusia (human error). Disini membuktikan bahwa tidak hanya kondisi kapal yang baik tetapi kelengkapan peralatan, jumlah awak kapal yang cukup, disiplin, dan ketrampilan awak kapal mempelancar pekerjaan. Bila sebaliknya, maka dapat menimbulkan resiko kecelakaan kerja yang tinggi, karena bekerja diatas kapal pada umumnya, dan pada kapal-kapal supply dilokasi pengeboran pada khususnya merupakan bentuk kerja keras yang penuh dengan tantangan dan resiko yang besar serta berbahaya, namun jika semua pekerjaan sesuai dengan prosedur kerja yang baik maka hal-hal tersebut dapat dicegah.Kata kunci : Dynamic Position, Dynamic Positioning System, Pengoperasian, Kapal Offshore Supply Vessel

In this paper we investigated the asymptotic distribution of the bootstrap parameter estimator of a first order autoregressive AR(1) model. We described the asymptotic distribution of such estimator by applying the delta method and employing two different approaches, and concluded that the two approaches lead to the same conclusion, viz. both results converge in distribution to a normal distribution. We also presented the Monte Carlo simulation of the residuals bootstrap and application with real data was carried out in order to yield apparent conclusions.

Jogjakarta is a tourist destination in Asia that earned the never-ending Asia. Until now culinary data is scattered everywhere so easily and quickly can be found with the help of internet. This results in uncertainty about the accuracy of information received by travelers. Therefore, a recommendation system is needed to make it easier for tourists to get the appropriate information. Collaborative Filtering is a widely used recommendation method because it has been shown to provide good results from previous studies. User-based collaborative filtering methods are used for cases with one criterion, but this developed recommendation system uses multicriteria for user data ranking to obtain appropriate recommendation results.

There are cases of patients with Acute Respiratory Infection (ARI) which are not handled quickly and appropriately at emergency department (ED), thus there should be a medium that can assist medical personnel in making decisions. This research proposes the development model of Clinical Group Decision Support Systems (CGDSS) named KLISPA models. KLISPA model can accommodate a screening process to the working diagnosis process of ARI by integrating Case Based Reasoning (CBR) and Groups Decision Support System (GDSS). Screening process completed by CBR using Nearest Neighbor method. This process helps medical personnel such as nurses, co asst doctors, and general practitioners to do screening to patients for determining the early solution to the disease. Meanwhile, the working diagnosis solved by GDSS uses the methods of Eckenrode, Extended TOPSIS and BoostVote. This process accommodates the needs of joint decision-making which involves groups of Decision Maker (DM) consisting of pediatrician, child lung specialist doctor, and the radiologist doctor.

Density estimation based on data is often use in engineering, finance, biomedical and social science data. People use parametric fit which specify the form of the density in advance, which very often is incorrect. Along with the development of computing software people can easily do the nonparametric methods, that rely heavily on computing but free from model assumptions. Kernel smoothing refers to a general class of techniques for nonparametric estimation of density functions. For certain univariate set of data that one wants to display graphically, using kernel function as the weight, this method can be used and is known as kernel density estimation.

Website adalah realisasi dari teknologi internet. Saat ini, seperti yang terlihat dari tren penggunaan, situs web telah berevolusi. Pada awalnya, situs hanya mengadopsi kebutuhan untuk mencari dan browsing informasi. Langkah awal peningkatan website sering dikenal sebagai teknologi 1,0 web. Saat ini, teknologi web 2.0 telah memungkinkan interaksi baik antar web-ke-web. Jenis interaksi seperti mengubah in formasi (sharing), dalam bentuk dokumen (SlideShare), gambar flickr), atau video (Youtube), informasi eksploitasi (wikipedia), dan juga penciptaan komunitas online (weblog, forum web) terutama layanan yang melibatkan masyarakat (inti dari web 2.0). Hal ini membawa dampak dan disebabkan oleh peningkatan interaksi sosial di dunia maya yang luas (internei) yang diikuti oleh munculnya interaksi pembelajaran dan pelatihan di mana seja-kapan saja yang disebut sebagai e-Learning. Pada dasarnya, belajar online memerlukan metode belajar mandiri dan kebiasaan belajar, yang sayangnya dimiliki oleh beberapa sumber daya manusia Indonesia. Kondisi yang terburuk dengan adanya sistem e-Learning sistem adalah karena e-Learning hanya bei fokus pada proses pengiriman konten substansi pembelajaran yang sama terhadap pelajar, meninggalkan aspek kognitif dan tidak menawarkan pendekatan atau pengalaman sendiri belajar interaktif dan juga meninggalkan adaptasi aspek pengguna dengan sistem. Oleh karena itu, agar e-Learning di Indonesia sukses diperlukan sistem e-Learning yang menerapkan teknologi web 2.0 agar para pelajar secara aktif berpartisipasi dan sistem yang menekankan personalisasi seperti kemampuan komprehensif, adaptif untuk tingkat kemampuan pelajar dan pengetahuan yang memiliki dukungan sumber daya. Dalam sistem e-Learning yang dibangun, ontologi akan diterapkan sebagai representasi makna pengetahuan dibentuk oleh para pelajar yang menggunakan sistem.

Pneumonia is an infection of the lungs that is caused by bacteria, viruses, fungi, or parasites. It is characterized primarily by inflammation of the alveoli in the lungs or by alveoli that are filled with fluid (alveoli are microscopic sacs in the lungs that absorb oxygen). The shortage of medical personnel at health community centers to serve a population often results in care delays for pneumonia patients. The purpose of this research is to make a modelling of group decision support system in diagnosing pneumonia in adult patients. The system is designed as a tool for medical personnel in diagnosing pneumonia patients.Group Decision Support System (GDSS) is developed by using Fuzzy Simple Additive weighting methods. The preference scoring of three experts i.e. a pulmonary specialist, an internist and a pharmacist is carried out by applying triangular fuzzy numbers. In the aggregation stage, preferences makes use of Fuzzy Linguistic quantifier, stage rangking employs Simple Additive Weighting while Forward Chaining is employed in the inference process. The system is tested by inputting the symptoms of pneumonia without the involvement of an expert. The results shows that the system is capable in diagnosing pneumonia.

The information-based approach asset pricing model by Brody-Hughston-Macrina is constructed based on the dividends information that can be accessed by investors at recent time in a financial market. Brody-Hughston-Macrina modeled the asset pricing at recent time for case of the cash flows value paying a single dividend at the certain time. The model is given by the expectation of the upcoming dividends conditional at the market information filtration under the risk neutral probability measure. The market information filtration is contained by the recent information flows that represent sum of the two of information i.e. the true information of dividends and the noise information in the financial market. Brody-Hughston-Macrina also constructed a model from setting that is a limited-liability asset that pays no interim dividends and is sold off at time fixed for the certain value. In this model, the recent information flows represent the sum of the market factor information and the noise information. Then this model is called a Black-Scholes Model from an Information-Based Perspective. Brody-Hughston-Macrina did imprecision in using of Gaussian Integrals to obtain the final result of the Black-Scholes Model from an Information-Based Perspective. This paper explains an imprecision for using of Gaussian Integrals in deriving the final result of the Black-Sholes Model from an Informative-Perspective, so it is found a different final model from the final model by Brody-Hughston-Macrina.

Model selection in neural networks can be guided by statistical procedures, such as hypothesis tests, informationcriteria and cross validation. Taking a statistical perspective is especially important for nonparametric models likeneural networks, because the reason for applying them is the lack of knowledge about an adequate functionalform. Many researchers have developed model selection strategies for neural networks which are based onstatistical concepts. In this paper, we focused on the model evaluation by implementing statistical significancetest. We used Wald-test to evaluate the relevance of parameters in the networks for classification problem.Parameters with no significance influence on any of the network outputs have to be removed. In general, theresults show that Wald-test work properly to determine significance of each weight from the selected model. Anempirical study by using Iris data yields all parameters in the network are significance, except bias at the firstoutput neuron.

E-learning content being a barrier for e-learning is no longer true on today’s Internet. The current concerns are how to effectively annotate and organize the available content (both textual and non-textual) to facilitate effective sharing, reusability and customization. In this paper, we explain a component-oriented approach to organize content in an ontology. We also illustrate our 3-tier e-learning content management architecture and relevant interfaces. We use a simple yet intuitive example to successfully demonstrate the current working prototype which is capable of compiling personalized course materials. The e-learning system explained here uses the said ontology.
