Noise Considerations for Propulsion System Evaluation
No full textThe laws and regulations regarding the radiated noise and the on-board noise of the ship are expected to be stricter in the future. There is a big concern in this field, especially for the underwater noise. The radiated noise from the ship is harming the life of the underwater mammals while the on-board noise is threatening the health of the on-board crew. One of the main contributors to the noise generated by a vessel is the propulsion system. It is true that the noise reduction can be achieved by doing the corrective action in the later design stage, such as installing mounting and noise absorption material. Nevertheless, the decision in early-design stage often gives the highest impact on the noise generated by the propulsion system where the level of uncertainty is high. This thesis has two main goals; to determine the design choices of propulsion systems which affect the noise excitation, and to develop an evaluation methodology to assess a certain power configuration from the perspective of generated noise. First, the aspects of the propulsion system that affect its noise are determined. Those are transmission types, number of engines, number of shafts and number of compartments. The loading point is also included as one of the parameters. Although it is not a design choice, it has a significant role in the noise generated by the propulsion system. Second, the selection of the significant noise source in the propulsion system needs to be done. There is much equipment inside a propulsion plant, but not all of them give sufficient contribution to the overall noise level. Based on the literature review, the equipment that is considered as the main noise sources are the diesel engine, the diesel generator set, the reduction gear and the electric motor. A noise model from SNAME is implemented in this project to predict the airborne and structure-borne noise source levels of the equipment and the transmission losses to the receiver location. An engine room-sizing model is developed in this project since the transmission loss is a function of the compartment dimensions. Furthermore, the room dimensions depend on the equipment dimensions. Therefore, it is necessary to develop a model to predict the size of the equipment too. Afterwards, the evaluation methodology is established to quantify the effect of a certain design choice towards the noise of a propulsion system. The effects of varying ship requirements are also investigated to see the behaviour of the model with a different input. These requirements are the ship installed power, the ship propulsion power and the ship auxiliary power This project provides a general guideline for the marine engineer to evaluate the propulsion system based on the noise considerations in the early design phase. The evaluation methodology proves to be applicable to a wide range of propulsion plant type. It is possible to extend the application of this method for a ship with prime mover other than the diesel engine and the electric motor. Marine Technology | Ship Design, Production and Operation

Penggunaan Penjaminan Buy Back Guarantie oleh Developer terhadap Kredit Pemilikan Rumah (Studi Kasus di Bank Bukopin Cabang Medan)
No full textNowadays, the competition in housing business is increasing. A cooperation
agreement between developers and the Bank with buy back guarantee is signed. It is
intended to cope with the problem of housing buy and sell in which the certificates
are not ready yet, or it is still in a master so that only the developer and the consumer
who sign the buy and sell form. When the certificate is ready, the consumer will be
summoned to sign for the second time, signing the buy and sell certificate with the
developer and the Bank since the certificate is used as collateral. This method is
actually very risky for the Bank as a financier since it does not have the right for
preference on collateral which is related to credit facility which has been given to
consumers/debtors. In order to cope with the risk problem, in the cooperative
agreement between the Bank and the developer, a promise from the developer is
attached in the contract. The developer intends to repurchase the collateral when the
credit given by the Bank to the debtor is suspended or nonperforming loan before the
certificate on the collateral is issued.
The research used judicial normative and descriptive analysis approach. The
data were gathered by using secondary data which consisted of primary, secondary,
and tertiary legal materials as the primary data. The gathered data were then
interpreted logically and systematically by using deductive thinking method.
The result of the research showed that the position and the role of the buy
back guarantee in the buy and sell transaction of housing unit with KPR facility was
that the developer would buy the land and building which had been sold if the debtor
ignored. Besides that, the guarantor would help the Bank until the Bank
obtained/controlled the land and its building. The collateral offered by the developer
will be effective sustainably until the debtor's debt to the Bank had been paid off. The
legal relation among the parties in fulfilling the obligation of buy back guarantee and
the legal relation between developer and debtor was reciprocal legal relation
through subrogation institution. The realization of buy back guarantee was that the
Bank/creditor had three alternatives to settle and return its rights,: the Bank carried
out its rights based on the contract with the debtor, or carried out its rights based on
the buy back guarantee contract.Saat ini dengan meningkatnya persaingan dari segi bisnis perumahan, antara
developer dengan Bank telah dibuat suatu perjanjian kerjasama dengan buy back
guarantie. Hal ini dimaksudkan untuk mengatasi masalah jual beli rumah dimana
sertipikat belum siap, atau masih induk sehingga antara developer dengan konsumen
menandatangani perjanjian pengikatan jual beli dan nanti setelah sertipikat sudah siap
untuk dilakukan jual beli, konsumen akan dipanggil kembali untuk penandatanganan
yang kedua, yaitu penandatanganan akta jual beli dengan developer dan pengikatan
agunan dengan Bank. Hal ini sebenarnya cukup berisiko bagi Bank selaku
penyandang dana, karena Bank belum mempunyai hak preferensi atas agunan
berkaitan dengan fasilitas kredit yang telah diberikan kepada konsumen/debitor.
Untuk mengatasi masalah resiko, maka dalam Perjanjian Kerjasama antara Bank
dengan developer dicantumkan suatu janji dari developer untuk membeli kembali
agunan apabila fasilitas kredit yang diberikan Bank kepada debitor tersebut tidak
lancar pembayarannya atau terjadi kredit macet sebelum sertipikat atas agunan
tersebut diterbitkan.
Metode penelitian yang digunakan adalah pendekatan yuridis normatif yang
bersifat deskriptif analisis, pengumpulan data dilakukan dengan menggunakan data
sekunder berupa bahan hukum primer, sekunder dan tertier sebagai data utama. Datadata
yang diperoleh kemudian diolah, dianalisis dan ditafsirkan secara logis,
sistematis dengan menggunakan metode berpikir deduktif.
Dari hasil penelitian diketahui bahwa kedudukan dan peranan penjaminan buy
back guarantie dalam transaksi jual beli unit perumahan dengan fasilitas KPR adalah
developer akan membeli tanah dan bangunan yang telah terjual dalam hal debitor
lalai, selain itu penjamin akan membantu bank sampai bank mendapat/menguasai
tanah dan bangunan, jaminan yang dilakukan developer akan berlaku terus menerus
dan berlangsung sampai hutang debitor kepada bank telah dibayar lunas. Bentuk
hubungan hukum para pihak dalam pemenuhan kewajiban penjaminan buy back
guarantie adalah hubungan antara Bank dengan debitor diatur dalam perjanjian
kredit, sedangkan antara bank dengan developer diatur dalam perjanjian buy back
guarantie, kemudian antara developer dengan debitor hubungan hukum yang timbul
adalah melalui lembaga subrogasi. Mengenai realisasi jaminan buy back guarantie,
bank/kreditor mempunyai 2 (dua) alternatif pilihan untuk menyelesaikan dan
mengembalikan haknya, yaitu Bank melaksanakan hak-haknya berdasarkan
perjanjian yang dibuat dengan debitor, atau melaksanakan hak-haknya berdasarkan
perjanjian buy back guarantie.124 HalamanTesis Magiste
Analisis perbandingan wireless network standard 802.11a dan 802.11p berdasarkan protokol dynamic source routing di lingkungan vehicular ad hoc networks
No full textRouting pada Vehicular Ad Hoc Network (VANET) merupakan kasus yang unik karena tingginya perubahan jaringannya. VANET sendiri juga digolongkan dalam Mobile Ad Hoc Network (MANET), sehingga protokol-protokol routing yang ada pada MANET dapat juga dipakai pada VANET. Pemilihan protokol routing menjadi salah satu aspek yang cukup penting. Oleh karena itu, penelitian ini akan melakukan evaluasi seberapa kuatnya protokol Dynamic Source Routing (DSR) dalam menghadapi berbagai skenario VANET yang memiliki kepadatan bervariasi di dalam lalu lintas perkotaan. Digunakan protokol 802.11p dalam ruang lingkup lalu lintas perkotaan yang didapat dari SUMo simulator, dan dianalisa menggunakan NS-2. Pemilihan 802.11p juga dipilih dari hasil perbandingan antara 802.11p dan 802.11a pada ruang lingkup lalu lintas yang berbentuk grid yang didapat juga dari simulator yang sama. Dari hasil analisa menunjukkan bahwa 802.11p memiliki performa yang lebih bagus dan bervariasi terhadap kepadatan-kepadatan yang telah ditentukan. Routing on Vehicular Ad Hoc Network (VANET) is a unique case due to the high network changes. VANET itself is also classified in Mobile Ad Hoc Network (MANET), so the MANET routing protocols can also be used on VANET. Selection of routing protocols becomes one of the most important aspects. Therefore, this study will evaluate how strong the Dynamic Source Routing (DSR) protocol in dealing with various VANET scenarios that have varied densities in urban traffic. This research is using an 802.11p protocol that obtained from SUMO simulator and then analyzed by NS-2. The 802.11p protocol was selected based on the result of performance comparison between 802.11p and 802.11a on some grid-shaped traffic scenarios. The results show that 802.11p has better performance and more robust than 802.11a while using predefined densities. </jats:p

Biometric is one method that can be used as a security device. One type of biometric that is widely used is biometrics with voice input. Each human has a different voice identity and the sound produced by humans can be sourced from the dental occlusion or tooth click. The signal from the dental occlusion will have some certain coefficients after being processed with the MFCC (Mel Frequency Cepstrals Coefficients) feature. In this study, we used a tool called an in-ear microphone as a voice signal receiver and the MFCC processing signal was then used as data training and the rest as data testing, which was processed using machine learning to analyze its accuracy. The results show that the accuracy of training data and testing data is 99.3% and 98% using machine learning type SVM (support vector machine). Meanwhile, the accuracy of training data and testing data using machine learning type of neural network is 100% and 98%
Kebijakan Deregulasi dan Debirokratisasi Regulasi Ekonomi Kemaritiman sebagai Katalisator Nawacita Indonesia Poros Maritim Dunia
No full textIndonesia merupakan salah satu negara kepulauan (archepelagic state) terbesar di dunia yang dianugerahi dengan berbagai macam potensi kemaritiman di dalamnya. Sejak pasca-reformasi tepatnya pada pemerintahan Jokowi-JK paradigma pembangunan ekonomi nasional mulai berubah yang semula bertumpu pada daratan semata (land based economy) kini beralih ke arah ekonomi kemaritiman (maritime based economy). Salah satu perangkat lunak pembangunan ekonomi nasional adalah regulas sebagai instrumen yuridis yang digunakan untuk menjamin kepastian hukum, jika masih terdapat regulasi yang ada mengalami duplikasi, redundansi, dan irrelevant regulations yang menghambat pembangunan, maka perlu adanya kebijakan deregulasi dan debirokratisasi agar percepatan pembangunan ekonomi kemaritiman dapat segera teralisasi. Adapun tujuan penulisan ini adalah untuk mengetahui implementasi kebijakan deregulasi dan debirokratisasi regulasi ekonomi kemaritiman serta untuk mengetahui implikasi dari kebijakan tersebut. Hasil penelitian menunjukkan bahwa implementasi deregulasi dan debirokratisasi telah dilaksanakan melalui serangkaian paket kebijakan ekonomi yang dikeluarkan pada September tahun 2015. Total ada 139 regulasi direlaksasi mengalami deregulasi dan debirokratisasi dengan berbagai klasifikasi kegiatan mulai dari kemudahaninvestasi, efisiensi industri, kelancaran perdagangan dan logistik, serta kepastian bahan baku sumber dalam negeri, untuk kemudian ditindakanjuti oleh Pemerintah Daerah. Dampak dari deregulasi dan debirokratisasi belum membuahkan hasil, sekitar 8 dari 11 regulasi yang telah direlaksasi belum dapat diimplementasikan secara optimal. Hal tersebut disebabkan oleh lambannya tindaklanjut Pemerintah Daerah yang memiliki kendali terhadap kegiatan industridan bisnis lainnya di daerahnya masing-masing. Maka dari itu perlu adanya keseriusan lebih dari Pemerintah Daerah untuk menunjang paket kebijakan deregulasi dan debirokratisasi regulasi ini agar berjalan dengan maksimal, serta agar percepatan pembangunan ekonomi kemaritiman dapat segera terwujud

Between the United States and China: Philippines foreign policy in the case of South China Sea
No full textIn 2016 there were several events that could change the Philippines' foreign policy in Southeast Asia. The tensions in the South China Sea were growing since several parties claimed the sea, and there were new presidents elected in the Philippines and the United States. This thesis focuses on the Philippines' strategy in this complicated geopolitical situation between the two great powers, the United States of America and China. The aim of this thesis was to identify how the Philippines respond to the changing geopolitical dynamics in the region after 2016 in the case of the South China Sea and which strategy they are using in their actions. The author explains the situation in the region, defines a small state, and then discusses the potential strategies a small state has in the case. The author set a hypothesis that the Philippines mainly use a hedging strategy to respond to the region's geopolitical dynamics. To test the hypothesis, the author conducted content analysis on the Philippines president Rodrigo Duterte's speeches, statements, interviews, and press conferences between 2016-2020. There were used official sources from the presidential web page. The purpose was to find statements related to the United States, China, or the South China Sea and identify the strategies. The author confirmed the hypothesis. Several strategies were used to maneuver in this complicated geopolitical situation, such as balancing, bandwagoning, hedging, and engaging. According to the theoretical part and Duterte's statements, the main strategy used between 2016-2020 was hedging.https://www.ester.ee/record=b5451257*es
De-stalinisation of soviet foreign policy towards Indonesia: reviewing the feasibility of the theory of foreign policy change
No full textThis paper re-evaluates the changing policies of the Soviet Union towards Indonesia during the era of Joseph Stalin and Nikita Khrushchev, by applying the contemporary theory of foreign policy change. After discussing the debates revolving around the theory of foreign policy change from Gustavsson and Hermann, this paper contends that if there were any changes, then the causal factors would likely be the interplay between the domestic factors and international factors, as Putnam has argued. This finding enhances the understanding that the domestic de-Stalinisation process undergone during Khrushchev’s era was not the only factor that might affect Soviet’s foreign policy. By using the case of Indonesia as the representation of the developing countries, the author shows that both sets of factors affected the changing policy. However, author also found that the systemic condition of the Cold War, namely the contestation between the US and USSR, was more influential than the domestic condition. This paper contributes to the deeper understanding of Soviet-Indonesia relations, the effect of domestic de-Stalinisation to foreign policy, and the feasibility of applying current theory of foreign policy change to an historical case
Assessment on the effect of flood defences asset management maturity to cost and performance
No full textMaturity model has proven to be helpful for an organization to identify its current capability, strength, and weaknesses through maturity levels. These levels are used to rank the various dimension or process of an organization. However, maturity levels only describe a general description of organization capability. The effect of different maturity levels towards the organizational outcomes is speculated in the basis of the description at each maturity levels. The use of the maturity levels is limited in the pre-determined description. This research is an attempt to foresee the effect of different management maturity towards asset cost and performance by using Dynamic Bayesian Network. The network is developed by using a semi-hypothetical case on grass revetment management. The network models the maintenance process which covers the asset degradation and the influence of different extent of management towards grass condition in time. The degradation probability was determined by using Cooke’s classical model expert judgment. We designed different network involving four management dimension that was translated as model scenarios. The result provides an insight into the potential gain or loss of different management maturity which is beneficial for organizations in evaluating different alternatives of management improvement.FAIR ProjectCivil Engineering | Hydraulic Engineerin
