Selang Kepercayaan The Generalized Confidence Interval (GCI) untuk Koefisien Variasi dari Distribusi Invers Gaussian
Authors: Nurkamilah Aneu , Kudus Abdul
Published: September 2023

Abstract. One of the distribution functions known in statistics is the Inverse Gaussian (IG) distribution. The IG distribution is used to deal with data that has a positive or right-skewed slope. The IG distribution was first introduced by Schrodinger in 1915 which originated from Brownian motion theory. In further statistical studies there is what is known as the coefficient of variation (CV), which is the ratio between the standard deviation and the mean value. In addition to point estimates, it is often desirable to find confidence intervals. One method to estimate the confidence interval of the CV coefficient is The Generalized Confidence Interval (GCI) method. In this thesis, the GCI method will be applied to the coefficient of variation of the IG distribution on PM 2.5 air pollution data. In the research process, the stages of analysis carried out include calculating the estimated parameters of the IG distribution using the maximum likelihood method, Kolmogorov-Smirnov test, calculating the values of Rλ, Rμ, dan Rθ for GCI to get the set of Rθ and calculating the 95% confidence interval for the parameter value , namely the CV parameter. Based on the calculation results, it is obtained that the PM 2.5 data in Malang City in 2023 comes from an IG-distributed population and the GCI confidence interval with a 95% confidence level for the CV of the IG distribution on PM 2.5 air pollution data in Malang City in 2023 is in the range [0.25; 0.42].

Abstrak. Salah satu fungsi distribusi yang dikenal dalam ilmu statistika adalah distribusi Invers Gaussian (IG). Distribusi IG digunakan untuk mengatasi data yang memiliki kemiringan positif atau miring ke kanan. Distribusi IG pertama kali diperkenalkan oleh Schrodinger tahun 1915 yang berasal dari teori gerak Brown. Dalam kajian statistika lebih lanjut ada yang dikenal dengan koefisien variasi (CV) yaitu perbandingan antara standar deviasi dengan nilai rata-rata. Selain nilai dugaan titik, seringkali juga diinginkan untuk mencari selang kepercayaan. Salah satu metode untuk menduga selang kepercayaan koefisien CV adalah metode The Generalized Confidence Interval (GCI). Dalam skripsi ini akan dilakukan penerapan metode GCI untuk koefisien variasi dari distribusi IG pada data pencemaran udara PM 2.5. Dalam proses penelitian tahapan analisis yang dilakukan meliputi menghitung taksiran parameter dari distribusi IG menggunakan metode maksimum likelihood, uji Kolmogorov-Smirnov, menghitung nilai Rλ, Rμ, dan Rθ bagi GCI hingga mendapatkan himpunan Rθ dan menghitung selang kepercayaan 95% untuk nilai parameter  yakni parameter CV. Berdasarkan hasil perhitungan diperoleh bahwa data PM 2.5 di Kota Malang tahun 2023 berasal dari populasi yang berdistribusi IG dan selang kepercayaan GCI dengan tingkat kepercayaan 95% untuk CV dari distribusi IG pada data pencemaran udara PM 2.5 di Kota Malang tahun 2023 adalah berada di dalam rentang [0.25; 0.42].
Optimasi Parameter Support Vector Machine menggunakan Particle Swarm Optimization untuk Bearing Fault Diagnosis
Authors: Rizki Aulia Hawa  , Sutawanir Darwis
Published: September 2023

Abstract. To assist industrial activities in generating power, humans create components that are developed through machines. One of the key elements that plays an important role in the process of a shaft rotation movement on the machine is the bearing. Given their widespread use, bearing vibration components can predict machine breakdowns or forecast indicators by leveraging forecasting models to diagnose bearings before failure occurs. One of the popular methods used for forecasting machine failure is the Support Vector Machine (SVM) which was introduced by Cortes and Vapnik in 1995 to overcome the problem of dividing two conflicting groups when demonstrating superiority in nonlinear small sample pattern recognition. SVM is optimized by incorporating Particle Swarm Optimization (PSO). The advantage of the PSO method is that it is able to produce accuracy values that are more precise and accurate than other mathematical algorithms and heuristic techniques (Pambudi, Wihandika, & Putri, 2019).

Untuk membantu aktivitas industri dalam menghasilkan tenaga, manusia menciptakan komponen yang dikembangkan melalui mesin. Salah satu bagian elemen kunci yang berperan penting dalam proses suatu gerakan putaran poros pada mesin adalah bearing. Mengingat penggunaannya yang luas, komponen getaran bearing dapat memprediksi kerusakan mesin atau indikator peramalan dengan memanfaatkan model peramalan untuk mendiagnosis bearing sebelum terjadinya kerusakan. Salah satu metode yang populer digunakan untuk peramalan pada kerusakan mesin adalah Support Vector Machine (SVM) yang diperkenalkan oleh Cortes dan Vapnik pada tahun 1995 untuk mengatasi masalah pembagian dua kelompok yang saling bertentangan saat menunjukkan keunggulan dalam pengenalan pola sampel kecil nonlinier.SVM dioptimalkan dengan menggabungkan Particle Swarm Optimization (PSO). Kelebihan dari metode PSO ini adalah mampu menghasilkan nilai akurasi lebih tepat dan cermat daripada algoritma matematika dan teknik heuristik yang lain (Pambudi, Wihandika, & Putri, 2019). Pada Analisis data bearing CWRU, hasil akurasi yang didapat dengan menggunakan algoritma SVM lebih unggul daripada hasil akurasi yang didapat dengan menggunakan PSO.

Abstract. Insurance is an agreement between the guaranteeing party and the guaranteed party where the guaranteeing party agrees with the guaranteed party to receive a premium as a replacement for losses, which will later be experienced due to events that have not yet occurred. Insurance is divided into two parts, namely general insurance and life insurance. One product of loss insurance is motor vehicle insurance. In several previous studies, there are many distributions that have been applied to insurance data (claims big data). Insurance and economic data are often positive and the distribution is usually skewed to the right. One of the most well-known parametric models with distributions that are usually skewed to the right is the inverse Gaussian which is a family of two-parameter distributions namely µ and λ. The material used in this thesis is big data on partial loss claims for motor vehicle insurance insurance company PT. ABC in 2019 Category 1 Region 2. The results of applying the inverse Gaussian distribution show that the large data for Category 1 motor vehicle insurance claims for Region 2 come from populations with an inverse Gaussian distribution.

Published: September 2023

Abstract. Pamulang District as the area with the highest number and population density in South Tangerang City encourages high interaction, mobilization and use of energy, especiallu energy from urban activities which has an impact on air pollution and contributes to the formation of the condition of South Tangerang City as a city with the worst air quality in Indonesia based on IQ Air Survey on 2019. This analysis uses the IPCC Guidelines 2006 method to determined the amount of CO2 emissions released from energy consumption of urban activities in Pamulang District. Based on the results of the analysis, it is known that the total of CO2 emissions from the residential activities in Pamulang District reach 1076402 ton.CO2/year. Existing green open space in Pamulang District which function as CO2 emission reduction are only able to absorb 22.094 ton.CO2/year, so it is necessary to develop green open space to be able to optimally reduce CO2 emissions from residential activities, namely by intensifying green open space which is focused on green open space along the Siliwangi Road corridor, open green space along rivers in Situ Pamulang and Angke River, and green open space around the monument and Alun-Alun Pamulang; as well as extending green open space in the form of an additional 151 Ha which  can be optimized by developing vertical and roof garden.

Abstrak. Kecamatan Pamulang sebagai wilayah dengan jumlah dan kepadatan penduduk tertinggi di Kota Tangerang Selatan mendorong tingginya interaksi, mobilisasi dan penggunaan energi khususnya energi dari kegiatan permukiman yang berdampak pada pencemaran udara serta memberi kontribusi terhadap terbentuknya kondisi Kota Tangerang Selatan sebagai kota dengan kualitas udara terburuk di Indonesia berdasarkan survey IQ Air 2019. Analisis ini menggunakan metode IPCC Guidelines 2006 dan Metode Box Model untuk mengetahui besaran emisi CO2 yang dikeluarkan dari konsumsi energi kegiatan permukiman di Kecamatan Pamulang. Berdasarkan hasil analisis, diketahui bahwa total emisi CO2 dari kegiatan permukiman di Kecamatan Pamulang mencapai 236.329 ton.CO2/tahun. Ruang terbuka hijau eksisting di Kecamatan Pamulang  yang berfungsi sebagai pereduksi emisi CO2 hanya mampu menyerap 215.825 ton.CO2/tahun, sehingga dibutuhkan pengembangan ruang terbuka hijau agar mampu mereduksi gas emisi CO2 dari kegiatan permukiman secara optimal yaitu dengan intensifikasi RTH yang difokuskan pada RTH di sepanjang koridor Jalan Siliwangi, RTH sempadan sungai di Situ Pamulang dan Sungai Angke, serta RTH pada sekitar Tugu dan Alun-Alun Pamulang; serta dengan ekstensifikasi RTH berupa penambahan seluas 151 Ha yang dapat dioptimalkan dengan mekanisme taman vertikal dan taman atap.

Authors: Anifa Deby Shafa , Darwin Ira Safitri
Published: September 2023

Abstract. Traditional markets are synonymous with negative stigma, such as dirty, disorderly places, minimal facilities, and the character of places that are prone to fraud. Simpang Dago market in the city of Bandung, which has a negative stigma, is also affected by the problems of irregular street vendors, traffic, and trade zoning. Simpang Dago Market revitalization has been carried out several times, but has not produced a significant impact. In fact, the revitalization in 2015 and 2019 has not resolved the problem of irregular street vendors, traffic, and trade zoning. The planned outputs in the Bandung City RDTR 2015–2035 and Bandung City RTRW 2022–2042 direct the expansion of the trade and service area in the Simpang Dago area. This has the potential to deal with problems that have not ended yet, by expanding Simpang Dago Market area inward which currently has an area of 3,610.05 m². The expansion of the Simpang Dago Market area has not been determined and studied further, so this research is important to overcome the irregularity problem. Calculations for the expansion of the Simpang Dago Market area in Bandung City used a mixed methods approach with descriptive and spatial (GIS-based) analysis methods. The results showed that Simpang Dago Market area could be planned for an inward expansion of 10,680 m² with an increase in the market classification to type II according to SNI 8152:2021 Public Market.

Abstrak. Pasar tradisional identik dengan stigma negatif, seperti tempat yang kumuh, kotor, tidak beraturan, fasilitas yang minim, serta karakter tempat yang rawan terjadi kecurangan. Pasar Simpang Dago Kota Bandung dengan stigma negatif tersebut turut terdampak permasalahan ketidakteraturan PKL, lalu lintas, serta zonasi perdagangan. Revitalisasi Pasar Simpang Dago sudah beberapa kali dilakukan, tetapi belum menghasilkan dampak yang signifikan. Bahkan, revitalisasi di tahun 2015 dan 2019 belum mengatasi permasalahan ketidakteraturan PKL, lalu lintas, serta zonasi perdagangan tersebut. Keluaran rencana dalam RDTR Kota Bandung Tahun 2015–2035 dan RTRW Kota Bandung Tahun 2022–2042 mengarahkan perluasan kawasan perdagangan dan jasa di kawasan Simpang Dago. Hal ini menjadi potensi untuk menangani permasalahan yang selama ini belum berakhir, yakni dengan perluasan kawasan Pasar Simpang Dago ke arah dalam yang secara eksisting memiliki luas sebesar 3.610,05 m². Perluasan kawasan Pasar Simpang Dago belum ditentukan dan diteliti lebih lanjut, sehingga penelitian ini menjadi penting untuk mengatasi permasalahan ketidakteraturan tersebut. Perhitungan untuk perluasan kawasan Pasar Simpang Dago Kota Bandung menggunakan pendekatan mixed methods dengan metode analisis deskriptif dan spasial (GIS-based). Hasil penelitian menunjukkan bahwa kawasan Pasar Simpang Dago dapat direncanakan perluasan ke arah dalam sebesar 10.680 m² dengan peningkatan klasifikasi pasar menjadi tipe II sesuai SNI 8152:2021 Pasar Rakyat.

Authors: Gusti Estri Cinta Tyas , Laksmidewi Dwinita
Published: September 2023

In the case of Samsung Smartphone and celebrity Dian Sastrowardoyo in the Indonesian context, the study attempts to clarify the impact of celebrity endorsers on consumers' purchase intentions through the mediation of customer's perception of quality and customer's attitude towards the brand. Due to the pandemic's requirement that numerous activities be done online, the intensity of mobile phone use has also increased. Samsung capitalized on this trend by employing celebrity endorsements to flood various social media, particularly YouTube, with commercials. The results reveal that not all elements of a celebrity’s endorsement impact purchase intention. Perception of quality and attitude towards brand only mediate some elements. This mixed method study employed survey data from 252 people living or working in Jakarta, analyzed statistically using SEM-PLS and proceeded with the interview process. The study indicates that, aside from focusing on the qualities of celebrity endorsers, smartphone companies in particular need to anticipate some potential substitutes. Limitations of the study are also outlined, and directions for future research are considered too.

From Reviews to Revenues Website Design’s Role in Converting Opinions into Purchase Intentions
Authors: Bernardus Denny
Published: September 2023

This research is to examine and investigate the relationship between online reviews, web design, and buying interest in the context of online commerce. The purpose of this study is to investigate and investigate the relationship between online reviews and web design. According to the findings of this research, which employs both qualitative and quantitative methods, user reviews posted on the internet are an important tool for reducing informational inequality. This, in turn, influences consumer trust, which in turn influences the decisions that consumers make when they are making purchases. Concerns, however, including a lack of trustworthiness and the potential of incorrect evaluations, argue for a stronger level of intervention. These concerns call for an intervention level that is stronger. In this context, web design appears as a powerful moderating factor, having the ability to improve purchase confidence and interest by giving an appealing appearance and clear navigation. This can be accomplished through the use of a website that is well-designed. The findings of this study have management implications that can assist the e-commerce business in the creation of customer-focused platforms, ethical content efforts, as well as technological and design breakthroughs that break new ground.

Cloud computing has become an integral part of our lives, and today it is used almost everywhere. In general, cloud computing is a concept of providing IT resources in the form of services. There are two cloud computing models: deployment models, which differ in the type of cloud management and access to the cloud and the level of security, and service models, which differ in the level of service provision, which affects, among other things, the level of responsibility of the service provider and the consumer. Cloud services began to gain popularity in 2009, and the demand for them has grown exponentially every year. They became especially popular during the pandemic in 2019, when people had to stay at home without interrupting their work processes, and now, in post-covid times, they also remain popular due to their convenience, high availability, easy scalability and cost savings. Due to the widespread use of cloud computing services, a high level of security is required. Unfortunately, the popularity of cloud computing has its drawbacks – in addition to the fact that it is more difficult to monitor the security of a remote environment than the security of a local computer, there are many other threats. In today's reality, people use cloud computing technologies in large volumes, for example, at work, for personal purposes, etc., as they have great trust in these technologies. This is the reason why it is necessary to maintain a high level of security and constantly improve it. Cloud computing security threats are usually divided into confidentiality, integrity, and availability threats. To prevent the loss of confidential information, service providers must ensure its integrity. Users want to be sure that their data will not fall into the hands of an intruder or third-party services. Therefore, this article discusses the most common threats to data security and integrity in cloud computing and the existing methods that prevent these vulnerabilities and possible problems at different levels and with the help of different tools.

Cloud services have become popular due to their advantages over traditional computing. The cloud provides remote access to software, hardware, and other services. This has allowed companies to be more productive and enabled remote work. Cloud services have fewer hardware and infrastructure requirements, which reduces the cost of maintaining and supporting information technology. The future success of organizations will depend, not least, on the extent to which they implement cloud computing in their operations. According to forecasts, spending on cloud IT technologies will continue to grow and in 2025 will exceed spending on traditional IT technologies. Security of cloud services is becoming a critical issue as more and more companies complete their digital transformation. Despite the many benefits, cloud services also face their own security threats and challenges. Since cloud services store and process a significant amount of sensitive information, a cloud breach can lead to data leaks that can hinder business development and cause significant damage to a company's reputation. There are risks associated with the unavailability of cloud services in case of technical problems and dependence on external providers. Therefore, companies should carefully assess potential threats and take appropriate measures to protect their data and business in general when using cloud services. There are many methods to help determine how prepared your organization is for the growing number of threats. Threat modeling is one of the methods for predicting and preparing for possible threats. Using modeling frameworks allows you to allocate resources and plan possible actions during an attack. There are many modeling frameworks available, but it is important to remember that these frameworks have their advantages and disadvantages, so the choice depends on the context and needs of a particular system. Analyzing, evaluating, and comparing existing methods for modeling and protecting against threats in cloud services is the main objective of this article.

Currently, world civilization is taking significant steps in science and practice related to quantum calculations. Significant steps are being taken to achieve the competitive advantage of countries in the field of quantum information science and the practice of introducing quantum technologies. Scientific and practical research is first aimed at reducing the risks related to quantum computers on cybersecurity, economic and national security. Although the full range of quantum computers is still unknown, it is obvious that further technological and scientific leadership of states will at least partially depend on the country's ability to maintain a competitive advantage in quantum computing and quantum information science. However, along with the potential advantages, quantum calculations are likely to cause significant risks about economic and national security. Specific actions are determined that technologically developed states that begin a long-term process of transferring vulnerable computer systems to quantum-resistant cryptography. An important problem in cryptology is to analyze ways of reducing risks for vulnerable cryptographic systems and the state of their development, adoption and implementation at the international and national levels of post-quantum standards of asymmetric cryptotransformations of electronic signatures (ES), asymmetric ciphers (AC) and key encapsulation protocols (KEP). Therefore, the processes of reducing risks for vulnerable existing standardized cryptographic systems and determining the directions of development of mathematical methods and the study of the prospects for their application in the creation of standardized AC, KEP and ES are significantly significant. They are reduced to justification and definition of mathematical methods and mechanisms that will create promising (post-quantum) standardized AC, KEP and ES. The course of analysis, evaluation and results of comparison of existing and post-quantum asymmetric cryptotransformations of AC, KEP and ES, and standardization at the international and national levels, including for transitional and post-quantum periods, are the main objective of this article.

The features of using ultrasonic, electromagnetic and acoustic methods to counteract unauthorized recording of speech on sound recording devices are considered. The advantages and unused possibilities of the methods are noted. Ways to increase the effectiveness of the ultrasonic method of counteraction consist in using the two-frequency ultrasonic method, in positioning the device for emitting ultrasonic vibrations no more than two meters from the target, in using high-intensity ultrasonic vibrations, in using the ultrasonic method together with the acoustic method, and others. Ways to increase the effectiveness of the electromagnetic method consist in using amplitude-pulse modulation of the interference signal, narrowly directed antennas, a device with a maximum allowable power, and others; Ways to increase the effectiveness of the acoustic method consist in creating speech-like interference from the speech of the interlocutor (synchronized with speech pauses), reducing the distance between the source of interference radiation and the source of speech in relation to the distance between the interlocutors due to organizational protection measures. (adapted acoustic method).

The most promising is the adapted acoustic method having the greatest potential for guaranteed countermeasures, subject to the requirements for its optimal use.

Analyzing the results of the experiment, we conclude that the adapted acoustic method is the most effective. The effectiveness of the method confirms the suppression range from 1.8 m to 3.5 m depending on the device, for comparison, in the ultrasonic experiment, one of the indicators was 0.9 m, and in the electromagnetic experiment, even 0 m. The formation of interference through the acoustic channel is higher the described method ensures the universality of the proposed method to the type of device for suppressing unauthorized speech recording, regardless of the underlying method – electromagnetic, ultrasonic or acoustic.
