Abstract

This research is motivated by the increasing gas emissions produced by industrial, automotive and household activities which mostly use fossil energy as an energy source. CO2 capture is introduced to the use of gasification technology in an effort to reduce CO2 emissions which are one of the causes of the greenhouse effect. The role of microwave is also introduced as an effort to increase thermal efficiency and increase production and quality of syngas and its role in reducing tar which is known to be high in biomass gasification. The utilization of water vapor is also clearly disclosed and its effect on syngas products, especially hydrogen gas. The role of the parameters that affect the gasification process is analyzed to see which variant has the best role in improving the quality and quantity of syngas. Research development opportunities are presented by looking at research gaps and future prospects

Abstract

Konsep Leniency Program merupakan suatu upaya dalam memberantas kartel yang merupakan tindakan pelaku usaha yang melaporkan secara sukarela dan mandril kegiatan kartel sehingga data dibebaskan dari sanksi atau mendapatkan pengurangan sanksi. Pada prakteknya, Leniency Program telah diimplementasikan oleh banyak negara. Namun, Indonesia belum menerapkan secara efektif program ini dan masih menggunakan sistem penanganan yang lama dengan tingkat kesuksesan rendah. Tujuan dari kepenulisan ini adalah untuk mengetahui seberapa urgensi Leniency Program dalam memberantas praktik kartel di Indonesia. Metodologi yang digunakan pada isu hukum ini adalah tipe penelitian Yuridis Normatif dan menggunakan pendekatan peraturan perundang-undangan (statute approach) serta Pendekatan Konseptual (Conceptual Approach). Hasil dari penelitian ini menunjukkan bahwa masih besarnya problematika dalam pemberantasan praktik kartel di Indonesia. Hukum acara Komisi Pengawas Persaingan Usaha (KPPU) yang diatur melalui Undang-undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat belum mengakomodasi konsep leniensi. Disamping itu, sulitnya proses pembuktian kartel berdampak pada seringnya putusan KPPU berkaitan dengan praktik kartel dianulir oleh Pengadilan Negeri dan Mahkamah Agung. Oleh karena itu, Penulis menawarkan gagasan Leniency Program agar dapat diimplementasikan ke dalam Undang-Undang Nomor 5 Tahun 1999 tentang Larangan Praktek Monopoli dan Persaingan Usaha Tidak Sehat, supaya dapat mengurangi praktek kartel dan mengoptimalkan penegakan hukum kartel di Indonesia.

Abstract

Fuel oil and gas in the coming years will still be the main energy source in supporting community activities. However, the increase in world oil prices led to an increase in fuel prices including gas and kerosene. One of the alternative energy sources that can be used is the use of wood waste as fuel for households or industries in the form of biomass pellets (pellets). The purpose of this study was to determine the quality of wood pellets from laban wood (Vitex pubescens) based on SNI 8021: 2014. This study used laban wood powder from the stems, branches and twigs, and tapioca flour as adhesives. The size of the powder used was 40 mesh stuck in 60 mesh. The pellet stamping used a pressure of 60 kg/cm3. The wood pellets tested included moisture content, density, volatile matter content, fixed carbon content, ash content, and calorific value. The test results showed that the stems of laban wood pellets produced better qualities than the branches and twigs parts although they were not significantly different. The range of laban wood pellets from the middle stems, branches and twigs were 11.27 ̶ 11.62% (moisture content), density were 0.34 ̶ 0.53 g/cm3, ash content were 0.83 ̶ 1,05%, volatile matter content were 71.20-72.00%, carbon content were 14.93-16.38%, and calorific value were 4486.46 ̶ 4514.46 cal/g. The test results were within the requirement of the Standards of Indonesia (SNI 8021-2014), the Korea Standard (KFS), and the Jeman Standard (DIN51371), except the density was not within the requirement of the SNI 8021-2014 Standard and the Jerman Standard (DIN51371). The density of the stem section was within the requirement of the Korean standard.

Abstract

Dalam era transformasi digital, pengelolaan data kepegawaian secara manual tidak lagi efektif dalam memenuhi kebutuhan operasional perusahaan yang dinamis. PT. Kreasi Berdikari Infomedia masih menghadapi permasalahan dalam pengelolaan data absensi dan penggajian karena belum terintegrasinya sistem administrasi kepegawaian secara digital. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem informasi manajemen data karyawan berbasis web yang mendukung efisiensi kerja serta akurasi data. Metode pengembangan yang digunakan adalah Rapid Application Development (RAD), dengan teknik pengumpulan data melalui observasi, wawancara, dan studi pustaka. Sistem dibangun menggunakan framework Laravel Filament dan MySQL sebagai basis data. Hasil implementasi menunjukkan bahwa sistem ini mampu mengotomatisasi proses pengelolaan data karyawan, mencatat kehadiran melalui teknologi RFID, serta menghasilkan slip gaji secara otomatis. Dengan adanya sistem ini, efisiensi kerja bagian HR meningkat dan akses data menjadi lebih terstruktur serta real-time..
