Warisan et al, 2019.The Content of Lysine and Growth of Snakehead Fish (Channa striata) Fed by Different Feed. pp. 384-393. Essential amino acids are amino acids that cannot be synthesized by the body so that they require outside intake. One of the essential amino acids in snakehead fish is lysine. Lysine plays a role in the process of antibody formation, blood circulation and growth. The feed given to snakehead fish that is cultivated also determines the content of snakehead lysine. The purpose of this study was to determine the content of lysine and the growth of snakehead fish fed differently. The study was conducted from May to July 2018 at Laboratorium Kolam Percobaan, Faculty of Agriculture and Laboratorium Bioproses, Faculty of Engineering of Sriwijaya University. The study was designed using a completely randomized design with three treatments, each repeated four times. The Treatments are the different types of feed given, P1 fish were given commercial feed with 32% protein; P2 fish is given commercial feed with 32% protein and 3.5% black cumin added; P3 fish are fed with fresh water and sea water fish flesh in a ratio of 1: 1. Fish cultured is carried out for 30 days in hapa in a concrete pond. Density of fish is 2 fish per liter. Fish are fed at satiation with a frequency of three times a day. The snakehead fish treated with freshwater and marine trash fish produced the highest increase in lysine content, which was 0.060 mg / ml while P1 was 0.024 mg / ml and P2 0.031 mg / ml. The absolute growth of snakehead fish in each treatment was P1 1.34 cm; P2 1.24 cm; P3 is 1.93 cm and absolute weight growth is P1 2.31 g; P2 2.17 g; P3 3.58 g. The results showed that different types of feed were not significantly affected the levels of snakehead fish lysine but significantly affected the growth of snakehead fish.

Abstract

Seiring dengan Perkembangan teknologi akses internet telah mencapai tahapan yang lebih mempermudah penggunaannya dengan memanfaatkan media akses jaringan wireless atau disebut dengan nirkabel, jaringan komputer wireless merupakan teknologi yang sering digunakan diberbagai instansi, perusahaan, cafe, toko,dan lain-lain. Jaringan wireless tidak hanya digunakan pada intsansi saja, tetapi sebagian rumah tangga juga menggunakannya. Masalah yang perlu diperhatikan pada jaringan wireless adalah keamanannya. Apabila keamanan jaringannirkabel tersebut memiliki celah, maka akan mudah dimanfaatkan celah tersebut ole horang yang tidak bertanggung jawab. Hal ini dapat merugikan bagi Instansi yang memiliki jaringan nirkabel tersebut. Salah satunya Sekolah Menengah Kejuruan (SMK) Negeri 3 Bengkalis merupakan sebuah sekolah menengah yang bertempat di Bengkalis. Pada saat ini SMK sudah menggunakan layanan jaringan wireless. Namun permasalahan yang terjadi di SMK saat ini adalah apabila pengguna ingin mengakses internet harus melakukan login terlebih dahulu dan masih bisa membuka situs yang tidak dibenarkan. Hal ini terjadi karena jaringan wireless berada di SMK menggunakan keamanan proxy. Di karenakan itu perlu menerapkan sistem keamanan wireless dengan Radius MAC Authentication sehingga pengguna tidak perlu login ulang saat berpindah tempat dalam satu area. Dengan adanya keamanan jaringan ini diharapkan dapat mempermudah pengguna jaringan wireless. Penelitian ini menghasilkan suatu sistem keamanan jaringan yang telah di konfigurasi dengan mikrotik, Dari beberapa pengujian keamanan wireless yang dilakukan jaringan wireless hanya bisa digunakan oleh pengguna yang terdaftar dan apabila pengguna berpindah tempat, pengguna tidak perlu login ulang.

Abstract

ABSTRAKIlmu hukum, yang dapat digambarkan sebagai disiplin fundamental dan esensial dalam konteks yurisprudensi yang lebih luas, berfungsi sebagai komponen kritis dan berpengaruh yang secara signifikan berkontribusi pada penilaian dan peningkatan efektivitas keseluruhan dan integritas kerangka hukum suatu negara dan pengaturan kelembagaan. Penelitian ini dengan cermat meneliti kerangka teoritis, prinsip-prinsip dasar, dan operasionalisasi ilmu hukum dalam kerangka sistem hukum Indonesia. Dari sudut pandang teori hukum, disiplin hukum melibatkan proses sistematis pengembangan, implementasi, dan penilaian ketentuan hukum dengan tujuan membangun infrastruktur hukum yang manjur dan selaras dengan kebutuhan masyarakat. Prinsip utama, termasuk kejernihan standar, ketidakberpihakan, keseimbangan antara kepentingan individu dan masyarakat, selain kemanjuran dan efisiensi kerangka hukum, merupakan subjek utama yang diperiksa dalam penelitian. Penelitian ini menggunakan metodologi kualitatif yang mengintegrasikan analisis normatif dan sosiologis, memanfaatkan data yang berasal dari tinjauan literatur, teks hukum, dan wawancara yang dilakukan dengan otoritas dalam domain undang-undang. Bukti empiris yang diperoleh dari penelitian menunjukkan bahwa, meskipun Indonesia memiliki kerangka legislatif yang kuat seperti yang digambarkan oleh Undang-Undang No. 12 Tahun 2011 tentang Pembentukan Peraturan Legislatif, proses legislatif sering menghadapi berbagai kendala. Tantangan tersebut meliputi lemahnya partisipasi publik dalam proses legislasi, pengaruh politik yang dominan dalam penyusunan undang-undang, serta kurangnya harmonisasi antara norma hukum dan kebutuhan masyarakat yang dinamis. Jurnal ini merekomendasikan penguatan reformasi dalam sistem legislasi, termasuk peningkatan keterlibatan masyarakat dalam proses penyusunan peraturan, peningkatan kapasitas lembaga legislasi, dan peninjauan berkala terhadap peraturan yang ada untuk memastikan relevansinya. Dengan memperbaiki kualitas perundang-undangan, diharapkan hukum di Indonesia dapat menjadi instrumen yang lebih efektif dalam menciptakan keadilan, memberikan kepastian hukum, dan memenuhi kebutuhan masyarakat secara berkelanjutan. Studi ini telah memberikan kemajuan penting dalam evolusi ilmu hukum, terutama dalam upaya membangun kerangka hukum yang responsif terhadap tantangan kontemporer.Kata Kunci: Ilmu Perundang-undangan, Sistem Hukum, Partisipasi Publik, Kepastian Hukum, Prinsip HukumAbstract Legal science, which can be described as a fundamental and essential discipline within the broader context of jurisprudence, serves as a critical and influential component that significantly contributes to the assessment and improvement of the overall effectiveness and integrity of a country's legal framework and institutional arrangements. This research carefully examines the theoretical framework, basic principles, and operationalization of legal science within the framework of the Indonesian legal system. From a legal theory perspective, legal discipline involves a systematic process of developing, implementing and assessing legal provisions with the aim of building a legal infrastructure that is efficacious and attuned to the needs of society. Key principles, including clarity of standards, impartiality, balance between individual and societal interests, in addition to the efficacy and efficiency of the legal framework, are the main subjects examined in the research.This research employs a qualitative methodology that integrates normative and sociological analysis, utilizing data derived from literature reviews, legal texts, and interviews conducted with authorities in the domain of legislation. Empirical evidence obtained from the research shows that, although Indonesia has a strong legislative framework as depicted by Law No. 12/2011 on the Formation of Legislative Regulations, the legislative process often faces various obstacles. Such challenges include weak public participation in the legislative process, dominant political influence in lawmaking, as well as a lack of harmonization between legal norms and the needs of a dynamic society.The journal recommends strengthening reforms in the legislative system, including increased public involvement in the drafting process, improving the capacity of legislative institutions, and periodic review of existing regulations to ensure their relevance. By improving the quality of legislation, it is hoped that the law in Indonesia can become a more effective instrument in creating justice, providing legal certainty, and meeting the needs of society in a sustainable manner. This study has provided important advances in the evolution of legal science, especially in the effort to build a legal framework that is responsive to contemporary challenges.

Abstract

Biaya produksi tertinggi pada budidaya ikan secara intensif berasal dari biaya pakan. Sebagian besar pembudidaya ikan sangat bergantung pada pakan komersial, yang harganya relatif tinggi. Pembuatan pakan secara mandiri menggunakan bahan baku lokal menjadi alternatif mengurangi ketergantungan pada pakan komersial, dan biaya produksi. Berbagai bahan baku lokal yang dapat digunakan dalam formulasi pakan ikan, satu diantaranya adalah ampas tahu. Penyebaran informasi hasil-hasil penelitian yang dapat diaplikasikan oleh masyarakat perlu dilakukan. Hal ini juga merupakan kegiatan Tridharma Perguruan Tinggi dibidang pengabdian kepada masyarakat. Kegiatan ini dilakukan bertujuan untuk memberikan informasi dan pelatihan kepada pembudidaya ikan tentang pembuatan pakan berbahan ampas tahu untuk ikan lele sehingga peserta memahami cara membuat pakan ikan secara mandiri.  Kegiatan dilaksanakan di Desa Pulau Semambu, Kecamatan Indralaya Utara, Kabupaten Ogan Ilir, Provinsi Sumatera Selatan, yang berlokasi tidak jauh dari kampus Universitas Sriwijaya. Metode yang digunakan pada pelatihan ini adalah demonstrasi cara pembuatan pakan ikan. Hasil kegiatan yang telah dilakukan dapat menambah wawasan dan pengetahuan teoritis dan praktis peserta tentang cara pembuatan pakan ikan lele. Hal ini terlihat dari peningkatan persentase jumlah peserta yang memahami materi yang diberikan, dari 20% menjadi 64%, atau meningkat sebesar 44%. Selanjutnya, pakan yang dibuat sesuai formulasi tersebut direkomendasikan untuk diaplikasikan pada ikan lele yang dipelihara untuk mengetahui pengaruhnya terhadap pertumbuhan dan efisiensi pemanfaatan pakan.
