Abstract

This study aimed to evaluate the quality and kinematics of spermatozoa in fresh and frozen semen of coastal cattle. Semen of coastal cattle was collected using an artificial vagina from 2 males, fresh semen was tested and frozen using tris egg yolk diluent. Fresh and frozen semen of coastal cattle were evaluated using a Computer Assisted Sperm Analyzer (CASA). This study used a t-test analysis by comparing the quality and kinematics of spermatozoa of fresh semen and frozen semen of coastal cattle. The parameters observed were macroscopic, microscopic and CASA quality observations. The results showed the kinematics of fresh and frozen semen motility (83.83%; 71.68%) and the kinematics of progressive motility of fresh and frozen semen (80.81%; 59.56%). Based on the results of the t-test analysis, it was found that t count > t table, the kinematics of fresh semen spermatozoa had a significant effect on the frozen semen of Pesisir cattle on the motility of fresh semen and frozen semen, on the progressive motility of fresh semen and frozen semen. The characteristic values ​​of kinematics in fresh semen and frozen semen of Pesisir cattle were respectively velocity curvilinear (VCL) 178.94 μm/s and 108.52 μm/s; velocity straight line (VSL) 96.61 μm/s and 49.34 μm/s; velocity average path (VAP) 114.99 μm/s and 64.04 μm/s; linearity (LIN) 0.53% and 0.44%; straightness (STR) 0.83% and 0.75%; wobble (WOB) 0.64% and 0.58%; lateral head displacement (ALH) amplitude 5.83 μm and 5.15 μm; beat cross frequency (BCF) 35.28 Hz and 24.65 Hz. The kinematics of fresh and frozen semen spermatozoa significantly affect the value of motility characteristics. The conclusion of the results of this study is that there is a decrease in the quality of fresh semen kinematics and frozen semen kinematics spermatozoa on the value of motility characteristics, namely on the speed of spermatozoa at the velocity curvilinear (VCL), velocity straight line (VSL), and velocity average path (VAP), linearity (LIN), straightness (STR), and wobble (WOB) and on the distance value of spermatozoa amplitude lateral head displacement (ALH) and beat cross frequency (BCF).

Abstract

Makalah Komprehensif Analisis Perubahan Jaringan Telekomunikasi Central Toka LIM 4 Wilayah Jatinegara Dari Saluran Tembaga Menjadi Fiber Optik bertujuan untuk menganalisis perubahan jaringan telekomunikasi dari saluran tembaga menjadi fiber optik. Untuk perubahan jaringan telekomunikasi dari saluran tembaga menjadi fiber optik di wilayah jatinegara menggunakan parameter seperti latency, packet loss dan troughput. Dalam perhitungan parameter yang membandingkan antara tembaga dengan fiber optik mendapatkan hasil bahwa untuk tembaga memiliki nilai yang lebih besar dibanding dengan nilai pada fiber optik. Kesimpulannya Fiber optik menjadi pilihan yang bagus untuk melakukan transfer data dan informasi yang akurat dibanding dengan menggunakan saluran tembaga. Nilai pada paramaternya menunjukkan untuk pengukuran latency pada fiber optik lebih kecil dari 3,7 ms sampai 5 ms dibanding dengan tembaga yang memiliki nilai 3,42 ms sampai 15,42 ms. Untuk nilai parameter pada pengukuran packet loss pada fiber optik memiliki nilai 0,64 % sampai 0,82 % dibanding dengan tembaga yang memiliki nilai 0,807 % hingga 0,88 %. Sedangkan untuk pengukuran throughput nilai fiber optik lebih besar dibanding dengan tembaga dikarenakan kecepatan dan keakuratan dalam melakukan transfer data setiap detik.

Abstract

Abstrak Permasalahan kemiskinan absolut yang masih membelenggu berbagai lapisan masyarakat Indonesia, terutama di wilayah urban dan peri-urban, menuntut solusi inovatif yang berkelanjutan dan inklusif. PKM ini menawarkan pendekatan berbasis ekonomi sirkular melalui pemanfaatan limbah kertas bekas sebagai bahan baku produk bernilai jual tinggi, seperti kerajinan tangan dan produk kreatif ramah lingkungan. Inovasi tidak hanya berkontribusi terhadap pengurangan limbah dan pelestarian lingkungan, namun membuka peluang ekonomi bagi kelompok rentan dan masyarakat berpenghasilan rendah. Program ini dirancang dalam bentuk kemitraan antara mahasiswa, pelaku UMKM daur ulang, dan komunitas lokal. Proses produksi akan didukung oleh pelatihan keterampilan daur ulang dan pengolahan limbah menjadi produk bernilai guna. Untuk memperluas jangkauan pemasaran, program ini mengintegrasikan teknologi e-commerce sebagai alat distribusi digital yang efektif. Melalui platform daring, produk-produk hasil olahan limbah kertas dapat dipasarkan secara lebih luas dan efisien, meningkatkan pendapatan masyarakat mitra, diikutin lebih kurang 25 orang karyawan PT Mahameru serta tim dari universitas indo global mandiri dosen dan mahasiswa. Tujuan utama dari kegiatan ini adalah menurunkan angka kemiskinan absolut melalui pemberdayaan ekonomi lokal yang berdampak lingkungan dan sosial. Hasil pelatihan peningkatan keterampilan masyarakat, penguatan jejaring usaha berbasis sirkular, dan kontribusi terhadap Tujuan Pembangunan Berkelanjutan (TPB/SDGs), khususnya Tanpa Kemiskinan, Pekerjaan Layak dan Pertumbuhan Ekonomi dan Konsumsi dan Produksi yang Bertanggung Jawab. Manfaatan teknologi digital, serta prinsip ekonomi sirkular, menjadi model pemberdayaan masyarakat yang dapat direplikasi di berbagai daerah dengan karakteristik serupa. Kata kunci: limbah kertas bekas; teknologi e.commerce; angka kemiskinan obsolute; ekonomi sirkular; berkelanjutan. Abstract The problem of absolute poverty that still shackles various levels of Indonesian society, especially in urban and peri-urban areas, demands innovative, sustainable and inclusive solutions. This PKM offers a circular economy-based approach by utilizing used paper waste as raw material for high-value products, such as handicrafts and environmentally friendly creative products. Innovation not only contributes to waste reduction and environmental preservation, but also opens economic opportunities for vulnerable groups and low-income communities. This program is designed as a partnership between students, recycling MSMEs, and local communities. The production process will be supported by training in recycling skills and processing waste into useful products. To expand marketing reach, this program integrates e-commerce technology as an effective digital distribution tool. Through an online platform, products processed from paper waste can be marketed more widely and efficiently, increasing the income of partner communities. Approximately 25 employees of PT Mahameru and a team from Universitas Indo Global Mandiri, including lecturers and students, participated. The main objective of this activity is to reduce absolute poverty through local economic empowerment that has environmental and social impacts. The training results in improved community skills, strengthened circular-based business networks, and contributed to the Sustainable Development Goals (SDGs), specifically No Poverty, Decent Work, Economic Growth, and Responsible Consumption and Production. The use of digital technology and circular economy principles provides a model for community empowerment that can be replicated in various regions with similar characteristics. Keywords: waste paper; e-commerce technology; absolute poverty rate; circular economy; sustainable.
