ANALISIS STATISTIK PITCH PADA AUDIO FORENSIK UNTUK BUKTI DIGITAL
No full textTeknologi informasi dan komputer terus berkembang dan telah dimanfaatkan secara luas maupun mendalam. Komputer/digital forensik merupkan aplikasi dari teknologi komputer untuk pembuktian hukum terkait dengan kejahatan berteknologi tinggi hingga bisa mendapatkan bukti bukti digital untuk menjerat para pelaku kejahatan. Wilayah forensik digital cukup luas karena jenis dari konten digital itu sendiri ada banyak, seperti website, email, gambar, audio, video, dan lain-lain. Pada kasus pidana maupun perdata diperlukan barang bukti, salah satunya adalah barang bukti digital/ elektronik. Barang bukti berupa audio recorder yang menghasilkan rekaman suara pembicaraan seseorang dengan orang lain merupakan salah satu barang bukti elektronik. Bukti rekaman suara melalui pemeriksaan audio forensik dapat diketahui identitasnya dengan metode komparasi. Metode ini membandingkan suara didalam rekaman barang bukti dengan suara yang direkam sebagai pembanding. Jika hasilnya identik maka dapat disimpulkan bahwa rekaman barang bukti berasal dari pemilik suara pembanding. Analisa pitch didasarkan pada kalkulasi statistik nilai pitch dari masing-masing suara unknown (Suara Asli) dan known (Suara Asli dengan Voice Changer). Berdasarkan eksperimen yang telah dilakukan pada contoh 20 kata yang diucapkan ditemukan perbedaan nilai analisis statistik pitch dari rekaman suara asli dengan suara yang diberikan voice changer.

Information technology and computers continue to evolve and have been widely and deeply utilized. Computer / digital forensics are applications from computer technology for legal evidence related to high-tech crimes to being able to obtain digital evidence to ensnare criminals. The area of digital forensics is quite extensive because there are many types of digital content, such as websites, e-mails, images, audio, video, and others. In both criminal and civil cases evidence is required, one of which is digital / electronic evidence. Evidence in the form of an audio recorder which produces a voice recording of a person\u27s conversation with another is one of the electronic evidence. The identity of recorded sound through audio forensic examination can be identified by means of a comparison method. This method compares the sound in the recorded evidence with the sound recorded for comparison. If the results are identical, it can be concluded that the recorded evidence comes from the owner of the comparator vote. Pitch analysis is based on statistical calculation of the pitch value of each of the unknown (Original Voices) and known (Original Voices with Voice Changer) voices. Based on experiments that have been carried out on examples of 20 spoken words, it is found that there is a difference in the value of the pitch statistical analysis of the original voice recording with the voice given by the voice changer.

CHILDFREE : MENGURANGI POPULASI MANUSIA UNTUK KESEJAHTERAAN DALAM PANDANGAN ISLAM DAN SOSIAL SAINS
No full textAbstrak. Dewasa ini banyak pasangan suami istri yang memilih childfree. Childfree merupakan sebuah kesepakatan antara suami dan istri untuk tidak memiliki keturunan. Masing-masing pasangan memiliki pertimbangan tersendiri untuk memilihnya. Fenomena ini kemudian menimbulkan pro kontra di masyarakat. Artikel ini akan membahas mengenai childfree ditinjau dari pandangan Islam melalui Al-Qur’an dan pemikiran ulama syafi’iyah yang diintegrasikan dengan masalah sosial sains di Indonesia. Penelitian ini menggunakan metode penelitian kepustakaan (library research) dengan pendekatan filosofis. Hukum childfree dikaji dari ayat-ayat Al-Qur’an dan perspektif ulama syafi’iyah yaitu Imam Ghazali dalam karyanya Ihya Ulumudin. Berdasarkan analisis, childfree diperbolehkan jika penolakan wujud anak disepakati sebelum potensial wujud, yaitu sebelum sperma berada di rahim perempuan. Kebolehan ini dapat berubah sesuai faktor yang mempengaruhinya, childfree yang dilakukan dengan menghilangkan sistem reproduksi, maka hukumnya menjadi haram. Adapun dari pandangan sosial sains, banyaknya populasi penduduk menjadi pertimbangan keputusan childfree demi kesejahteraan rakyat Indonesia.

Abstract. Today, there are many married couples who choose to be childfree. Childfree is an agreement between husband and wife not to have children. Each partner has their own considerations to choose it. This phenomenon raises the pros and cons in society. This article will discuss child-freedom from an Islamic perspective through the Qur\u27an and the thoughts of the Syafi\u27iyah scholars who are integrated with social science problems in Indonesia. This research uses a library research method with a philosophical approach. Child-free law is studied from the verses of the Qur\u27an and the perspective of the syafi\u27iyah cleric, Imam Ghazali in his work Ihya Ulumudin. Based on the analysis, child-free is allowed if the rejection of the child\u27s form is agreed before the potential form, i.e. before the sperm is in the woman\u27s womb. This permissibility can change according to the factors that influence it, if the child-free is done by eliminating the reproductive system then the law becomes haraam. As for the social science perspective, the large population is a consideration for child-free decisions for the welfare of the Indonesian people.

Assessing an Innovative Virtual Museum Application using Technology Acceptance Model
No full textThis study discusses the assessment of a virtual museum application development based on machine learning models for Palembang culture education through the Sultan Mahmud Badaruddin II museum cultural heritage by using the Technology Acceptance Model approach. The application was tested to measure the user acceptance of the application and pre-test and post-test to measure the effect size of the application as a learning media. A total of N=32 student participants were involved in testing the Sultan Mahmud Badaruddin II innovative virtual museum application for museum visitors was dominated by students who came to the museum to learn the culture and history of Palembang. Hypothesis testing results show that the perceived usefulness and perceived ease of use variables do not affect the attitude toward the use of the innovative virtual museum application. The attitude toward the use of the variable affects the behavioural intention to use, which directly also has a moderate effect on the actual use of the application where the dependent variables have the value of R2 > 0.5. The developed app is recommended as alternative learning media during a pandemic where the app testing participants express interest in using the app to enhance the Palembang culture learning experience
The WASPAS Method in Determining BSM Recipients Objectively
No full textThis research was conducted due to complaints from several parents regarding the determination of BSM at SDN Karanganyar 02 which still contains subjectivity in its selection so that some students are less fortunate. SDN Karanganyar 02, once a year always carries out activities related to determining the selection of BSM recipients. With this activity, it is hoped that students who are underprivileged but have fairly good achievements can receive this BSM so that the activities they carry out do not feel burdened with financial needs. The fact is that in institutions there are still many students who do not get BSM, even though according to the requirements these students should be eligible to get BSM. So in the selection that occurs there is a very irrational subjectivity. To solve this problem, the researcher tries to make a solution through an application that applies the Weight Aggregated Sum Product Assessment (WASPAS) method, which is a method of determining with predetermined criteria. The criteria in question are activities, achievements, report cards, parental income, home conditions, and parental dependents. After analyzing and implementing the WASPAS Decision Support System, it was found that the results were detrimental to students where the criteria scores and final determination were lower than some other students, but the SD carried out an assessment by obtaining BSM. To prevent this incident from recurring, WASPAS is very capable of answering objective determinations with the results obtained at 79.88% and the previous subjective determination at 20.12%
Optimasi Portofolio Saham Menggunakan Model Markowitz Berdasarkan Prediksi Harga Saham
No full textModel ARIMA dapat digunakan untuk memprediksi data dengan pola data linear masa lalu. Asumsi yang harus dipenuhi dalam model ARIMA adalah stasioneritas data. Pergerakan harga saham yang cenderung berubah memerlukan peramalan harga saham. Selain itu, untuk memaksimalkan keuntungan dan meminimalkan kerugian, investor dapat membentuk portofolio yang mengandung aset berharga yang dapat memberikan keuntungan bagi investor. Model Markowitz atau Mean – Variance Model merupakan salah satu model untuk membentuk portofolio optimal. Model Markowitz memberi investor opsi melalui perhitungan terperinci dari proporsi risiko, korelasi, dan kovarians yang terkandung dalam setiap aset portofolio. Dalam teori Markowitz terdapat diversifikasi Markowitz yang bertujuan untuk meminimalkan kerugian. Tujuan dari penelitian ini adalah mengkaji hasil simulasi penerapan Markowitz pada masalah optimasi portofolio. Jenis penelitian ini adalah penelitian deskriptif kuantitatif yang bertujuan untuk mengetahui prediksi harga saham dengan menggunakan metode ARIMA dan untuk mengetahui komposisi pembentukan portofolio yang dihasilkan dengan menggunakan model Markowitz. Sampel penelitian ini adalah saham PT. Aneka Tambang Tbk. (ANTM), PT. Indofood CBP Sukses Makmur Tbk. (ICBP), dan PT. United Tractors Tbk. (UNTR). Data yang digunakan dalam penelitian ini adalah data sekunder berupa harga penutupan bulanan untuk setiap sampel yang diperoleh dari situs resmi Yahoo Finance. Berdasarkan hasil analisis dan pembahasan yang dilakukan, total modal yang diperoleh investor mengalami peningkatan. Hal ini disebabkan oleh model Markowitz sebagai pengendali dengan memberikan batasan tertentu yang pasti dan sebagai pengambil keputusan terbaik berdasarkan prediksi harga saham dalam mengelola setiap modal dalam suatu portofolio aset

Instant messaging applications have a very important role in online interactions, especially during the COVID-19 pandemic. A safe and reliable instant messaging application for some people provides convenience and benefits. This paper examines network forensic experiments in the form of analysis of encrypted network traffic from the Synology Chat instant messaging application which identifies communication network traffic patterns using the Wireshark application. Tests in this study were carried out by direct experiments using infrastructure that is in line with the Man In the Middle test method, namely monitoring network traffic on client and server communications. Analysis is carried out by monitoring network patterns in the form of IP addresses and the size of packets sent and the protocol used. Network pattern monitoring is carried out on three channels, namely public group, private group, and personal message. Based on evidence that the packet size pattern sent by the public group has a pattern that is almost the same as personal chat and the private group has a larger packet size pattern than other channels. The dominant protocol uses TLSv1.2 as the protocol for sending encrypted data. Based on these findings, the pattern can be used as a guide if you want to carry out a forensic investigation on certain cases using the Synology Chat instant messaging application.
