QUALITY IMPROVEMENT OF FEED CHEMICAL COMPOSITION WITH THE ADDITION OF DRAGON FRUIT SKIN FLOUR (Hylocereus polyrhizus)

Providing high-quality feed is one of the efforts to increase fish productivity and growth and reduce fish mortality. One of the additional alternative feed ingredients as a source of vegetable protein is dragon fruit peel which can be used as an additional ingredient in fish feed. The study of the chemical composition of feed with the addition of dragon fruit peel flour is essential information to determine the effect of addition and the benefits of by-products (waste) from food processing in aquaculture development. This study aims to evaluate the quality of the chemical composition of feed after being treated with the addition of dragon peel flour through proximate analysis. The test was carried out at the Agricultural Product Technology Laboratory of Lampung State Polytechnic, from June to August 2020. The test results showed that dragon fruit peel flour had a carbohydrate content of 50.74%, crude fiber 26.22%, ash 21.35%, protein 5.08%, and fat 4.80% (dry weight). The test results showed that the addition of dragon fruit peel flour increased the protein content in the feed, which increased with the increase in the added dragon fruit flour. The highest protein content in treatment was 1.5%, namely 37.79% (dry weight), and decreased in the addition of dragon fruit flour by 2.0%. The highest ash content in the addition of 2.0% was 11.32% (dry weight). The content of crude fiber, carbohydrates and fat has decreased with the increasing dose of dragon fruit flour. The addition of dragon fruit peel flour can increase the protein content in the feed to substitute in the manufacture of fish feed. This also increases the utilization of dragon fruit peel waste, especially in aquaculture, to reduce waste disposal into the environment

Growth performance and survival rate of vannamei shrimp (Litopenaeus vannamei) post-larva stages in a super intensive cultivation system with varied densities

Vannamei shrimp (Litopenaeus vannamei) holds significant economic importance in Shrimponesia as a prominent shrimp commodity. The post-larval stage often encounters challenges, primarily due to the shrimp's limited ability to adapt and survive in a new environment. Stocking density is a crucial factor influencing the growth and production performance of vannamei shrimp culture. This study aims to assess the optimal stocking density for achieving optimal growth and survival in L. vannamei. A 40-day maintenance trial was conducted at UD Mina Rahayu Kalianda to investigate the impact of different stocking densities on water quality in the maintenance media. The study utilized containers with varying stocking densities: treatment A (1 shrimp/L), treatment B (1.5 shrimp/L), and treatment C (2 shrimp/L), each with three replications. The findings revealed survival rates (SR) of 83.33% for treatment A, 62.78% for treatment B, and 58.33% for treatment C. Mean Body Weight (MBW) values were recorded as 1.2592 g/shrimp for treatment A, 1.1216 g/shrimp for treatment B, and 0.7728 g/shrimp for treatment C. Average Daily Growth (ADG) results showed 0.0313 g/shrimp for treatment A, 0.0279 g/shrimp for treatment B, and 0.0192 g/shrimp for treatment C. Based on the study, the recommended stocking density for white vannamei shrimp is 40 shrimp/L, demonstrating improved growth and survival rates for this species

The Impact of Visfatin Level Against Blood Pressure Among Pregnant Women

Visfatin, a protein with a molecular weight of 52 kDa, has been demonstrated to increase in the bloodstream. Visfatin has been shown in several studies to be a potential marker of preeclampsia. The objective of this study was to describe visfatin levels in pregnant women in Gianyar, Bali. An observational design was employed in this study to describe visfatin levels in 41 pregnant women in Ubud, Gianyar regency, Bali. Visfatin levels were determined by examining EDTA blood samples using the Elisa method and reading them at 450 nm on a microplate reader. The average value of visfatin levels was 6.49 ng/ml, according to the results. The average visfatin level based on hypertension blood pressure respondents was 3.74 ng/ml. This result was lower than that of normal blood pressure respondents.  This study's decrease in visfatin levels may have a smaller effect on physiological insulin resistance. The average visfatin level in second trimester respondents was 7.9 ng/ml higher than 5.7 ng/ml in third trimester respondents. The increase in visfatin levels suggests that visfatin may play a role in the pathogenesis of preeclampsia. Visfatin has the potential to be used as a biomarker to detect preeclampsia earlier, allowing pregnant women with preeclampsia to receive appropriate treatment

Kondisi dunia bisnis saat ini sedang dalam perkembangan yang sangat pesat di dunia ini. Berbagai macam bisnis baik di bidang barang atau jasa sangat sekali diminati karena memiliki peluang yang cukup baik. Namun, kondisi seperti ini pastinya menimbulkan berbagai macam persaingan, salah satunya melalui internet karena kegiatan pasarnya yang tidak mengenal waktu. Banyak sekali timbul penyalahgunaan di internet salah satunya penyalahgunaan domain atau yang biasa disebut cybersquatting. Cybersquatting adalah salah satu bentuk pelanggaran Hak Kekayaan Intelektual (HKI). Pelanggaran ini sangatlah dilarang di Indonesia. Kegiatan ini biasanya meminta harga yang jauh lebih besar terhadap domain yang dimilikinya untuk dijual kepada perusahaan yang memilik merek dari domain tersebut. Hal ini dilakukan karena proses perolehan nama domain menggunakan first-come first-serve yang berarti orang yang mendaftarkan nama domain tersebut pertama kali merupakan orang yang akan dilayani atau akan mendapatkan domain tersebut. Pelanggaran ini akan berurusan dengan Undang-Undang Negara Republik Indonesia. Terdapat Undang-Undang No. 11 Tahun 2008 tentang Informasi dan Transaksi Elektronik dan Undang-Undang No. 15 Tahun 2001 Tentang Merek. Namun hanya Undang-Undang no. 15 Tahun 2001 yang memberikan sanksi secara jelas, hal ini yang mengakibatkan masih banyaknya terjadi cybersquatting di Indonesia
