Abstract

Energi terbarukan merupakan salah satu alternatif di tengah krisis energi. Salah satu sumber energi terbarukan adalah Biomassa. Biomassa berasal dari organisme seperti tumbuhan dan hewan serta limbahnya. Salah satu contoh penerapan biomassa sebagai sumber energi adalah limbah pabrik kelapa sawit. Penelitian ini bertujuan untuk mengetahui keekonomisan dari pemanfaatan limbah padat dari pengolahan kelapa sawit yaitu serabut (fiber) dan cangkang (shell) kelapa sawit sebagai bahan bakar Boiler untuk membangkitkan listrik. Metode yang digunakan dalam penelitian ini adalah menganalisis produksi dan pemanfaatan serabut dan cangkang sawit untuk disesuaikan dengan kebutuhan listrik pabrik sehingga bisa diketahui biaya energi dari pemanfaatan tersebut. Hasil penelitian menunjukkan bahwa PKS beroperasi selama 10 jam dengan kapasitas pengolahan 45 ton/jam. Setiap kelapa sawit yang diolah menghasilkan 6% cangkang dan 13% fiber, maka produksi cangkang sebesar 2.700 kg/ jam dan fiber sebesar 5.850 kg/jam. Bahan bakar yang masuk ke Boiler adalah 1.735,08 kg/jam untuk cangkang dan 5.189,34 kg/jam untuk fiber Rata-rata penggunaan listrik pabrik adalah 783 kWh maka bahan bakar yang dibutuhkan untuk membangkitkan listrik adalah sebesar 6,63 kg serat dan 2,22 kg cangkang per kWh. Biaya Energi dari pemanfaatan serabut dan cangkang kelapa sawit lebih mahal dibandingkan dengan solar yaitu sebesar Rp32.050.425/hari.

Abstract

This study aims to analyze the Sipadu application in the Manokwari Regency implemented by Civil Servants (PNS) to increase the administrative efficiency of absenteeism. Before the application came into action, absenteeism was controlled through attendance books or paper forms and everything took more time, then it was necessary to validate and adjust the data manually. The sheer volume of paper and equipment, managing, processing, and storing the attendance data also represented additional costs. The introduction of the Sipadu application shifted attendance recording from manual to automated system, so data entry and processing can be done in real time, paper and administrative equipment can be minimized, and the administrative process can be automated. According to the results of this study, attendance processing using the Sipadu application is faster, data accuracy is increased, and operational costs are reduced. Moreover, since there are automatic verifications in the application, the chances of repetition and tampering with data is reduced to keep the application transparent and reliable. Increasing employee satisfaction, as they are more focused on their activities no longer disturbed by absence input as a result of the benefits of implementing Sipadu linked with the attendance system that are efficient and transparent. This research shows that the Sipadu application as information technology solves the problems of absenteeism administration and public sector efficiency.

Abstract

Current technology has become a crucial part of an institution or company to help accelerate processes and minimize human errors. The General Election Commission (KPU) of South Manokwari Regency in West Papua Province, specifically, has not yet fully implemented leave permissions as stipulated in labor regulations for its employees, especially those bound by annual contracts. Similarly, the issuance of official travel orders (SPPD) for employees is hampered by administrative workforce issues, resulting in delays in the issuance of SPPDs as permits to leave the location for other out-of-town work. The Web-Based Application for Issuing SPPD and Leave Permits is created using the CodeIgniter framework, all of which are free licensed applications. With the design and development of this system and application, it is expected to maximize work time effectively by better controlling the leave of specialist service personnel and more efficiently managing business trips
