This study explores the efficacy of the Support Vector Machine (SVM) method in classifying mangosteen fruit images based on six ripeness levels. Employing SVM enables nonlinear data classification and simultaneous utilization of multiple feature extractions, resulting in enhanced accuracy. Analysis reveals that models integrating three feature extractions outperform those with only two. With ample training data and optimized parameters, SVM achieves detection accuracy exceeding 90%. However, algorithmic enhancements are necessary to compute RGB color index values for all pixels on mangosteen skin surfaces, possibly through circular-shaped windows approximating the fruit's contour. Moreover, comparative assessments of RGB color system calculations against alternative systems such as HSI are crucial for selecting the most suitable color model in alignment with human perception.

As a result of periodic shifts, technological advancements are becoming more varied. The payroll system for employees is one of them. Payroll must follow the company’s standard operating procedures (SOP) to determine several issues. Thus, the system can be customized to match the company’s specific needs and SOP. The administration and finance departments encounter difficulty processing employee payroll due to frequent errors in employee data entry, including position, department, income, and deductions. The absence of a payroll information system that can reliably and rapidly calculate employee salaries and provide timely reports has become the primary source of the difficulty. The designed employee payroll information system only processed PT. Bio Pilar Utama’s payroll data. Facilitating the administration and finance departments to input data, calculate salaries, store data, and generate reports on employee payroll could be achieved through the newly developed employee payroll information system.

Proses disposisi surat yang ada di BPKAD Kotawaringin Timur selama ini masih mengandalkan proses manual. Proses manual tersebut tentu tidak akan luput dari human error maupun sulitnya melacak history disposisi surat serta dapat menyulitkan proses pengarsipan. Dari permasalahan tersebut tentu sangat dibutuhkan sebuah aplikasi sistem informasi yang dapat digunakan untuk menangani proses disposisi surat. Pilihan yang sangat mungkin diterapkan yaitu mengembangan sistem dengan penunjukan langsung/melakukan kerjasama dengan sedikit tenaga programmer sesuai anggaran yang dimiliki. Untuk mengembangkan system informasi tersebut perlu ditentukan metode pengembangan yang sesuai dengan kondisi instansi. Dari beberapa metode yang ada, Extreme Programming ( XP ) merupakan sebuah proses rekayasa perangkat lunak yang cenderung menggunakan pendekatan berorientasi objek dan sasaran dari metode ini adalah tim yang dibentuk dalam skala kecil sampai medium serta metode ini juga sesuai jika tim dihadapkan dengan requirement yang tidak jelas maupun terjadi perubahan–perubahan requirement yang sangat cepat. Metode extreme programming dapat digunakan untuk membuat aplikas e-disposisi dengan segala keterbatas sumber daya baik dari sisi SDM maupun anggaran.Hasil pengujian menunjukkan bahwa aplikasi ini sudah memenuhi acceptance criteria yang tertuang pada user stories, sehingga aplikasi ini layak untuk digunakan.

– The problems regarding prisons are almost endless. The government should pay attention to this. The problems that arise today, almost all correctional institutions in Indonesia exceed (over) capacity, including those in the East Kotawaringin district . Indoor Positioning System IPS is a technology that can be used to locate people or objects in a building, usually through a mobile device such as a smartphone or tablet. Although this technology is newer than GPS, services utilizing IPS are quickly gaining ground in indoor locations such as shopping malls, hospitals, airports and other indoor venues. By utilizing an iBeacon mounted on a prisoner's wristband, the iBeacon will always transmit a signal that can be picked up by the receiver. Devices that can become receivers are bluetooth repeaters (signal boosters) and prison officers' android phones. To be able to know the estimated position of the receiver on the iBeacon, a map is needed locally, which is to determine a certain location, then map it in the form of coordinates. By placing several iBeacons at certain coordinates, it can be used to determine the estimated position of the receiver to the iBeacon.

Sekretariat Daerah terdiri dari beberapa bagian, salah satunya bagian hukum. Layanan Bantuan Hukum untuk kegiatan konsultasi hukum terdiri dari 3 sub kegiatan yaitu persiapan, pelaksanaan, serta pasca pelaksanaan. Secara geografis, banyak desa di Indonesia yang jauh dari sekretariat daerah. Kepala desa dan perangkat desa juga harus mengunjungi Sekretariat Daerah untuk mengatur penyuluhan dan bantuan hukum jarak jauh. Ini memakan waktu setidaknya satu hari dan biaya perjalanan/akomodasi tidak murah. Secara teori permasalahan yang ada dapat diatasi dengan membangun sebuah sistem pengolahan data yang berbasis teknologi informasi. Pada banyak organisasi, pengembangan perangkat lunak dan aktivitas operasi biasanya dilakukan secara terpisah dan memiliki tujuan yang terpisah. Pengembang bertugas membuat, menambah, dan memodifikasi sistem baru. Bagian operasi bertugas menjaga stabilitas sistem. Ini biasanya menyebabkan konflik ketika sistem baru akan diimplementasikan. Departemen operasi cenderung tidak menginginkan perubahan karena kekhawatiran tentang ketidakstabilan system. DevOps adalah tren baru yang muncul (tahun 2009) dari benturan dua tren lama: Agile Systems dan Agile Operations. Ini merupakan kolaborasi antara staf pengembangan dan staf operasi di setiap tahap siklus hidup DevOps. Metodologi DevOps tidak hanya mencakup fase pengembangan tetapi juga fase operasi. Fase yang disediakan cukup komprehensip sehingga sangat kecil kemungkinan aplikasi gagal untuk diimplementasikan secara berkelanjutan.

The rapid development of the business world has resulted in several changes to business actors in carrying out their business activities. This encourages the emergence of standard agreements as practicality in conducting transactions. This study aims to analyze consumer protection law and apply the principles of freedom of contract in standard agreements in online and retail financial services businesses—the descriptive qualitative method with data collection techniques using in-depth interviews and documentation studies. Informants were selected by purposive sampling. The results show that standard clauses have been regulated in Article 18 of the Consumer Protection Law. However, in practice, clauses are still found that violate and transfer responsibility to the detriment of consumers. Furthermore, regarding consumer dispute resolution, there is an overlap issue between the Financial Services Authority (OJK) and the Consumer Dispute Resolution Agency (BPSK). Therefore, if viewed from the principle of freedom of contract, the standard agreement cannot fulfill the principle of freedom of contract, and consumer protection, so especially in the financial services sector and retail, needs to increase preventive and repressive supervision by providing several alternatives dispute resolutions for disadvantaged consumers.
