Abstract

Kebutuhan energi dunia saat ini dapat disubstitusi dengan etanol sebagai bahan bakar alternatif. Bahan baku produksi etanol dapat menggunakan molases yang merupakan sisa pembuatan gula tebu namun masih mengandung glukosa dan nutrisi tinggi. Penelitian ini memanfaatkan limbah pabrik gula/molasess sebagai bahan dasar pembuatan etanol. Tetes tebu berupa cairan kental dan diperoleh dari tahap pemisahan kristal gula. Molases masih mengandung gula dengan kadar 50-60%, asam amino dan mineral. Tingginya kandungan gula dalam molases sangat potensial dimanfaatkan sebagai bahan baku bioetanol. Dalam penelitian konversi molases menjadi bioetanol pada bioreaktor menggunakan variabel konsentrasi berat Saccaromyces cerevisiae sebagai variabel bebas. Variabel tetap yang digunakan adalah pH 5, temperatur ruangan, kecepatan pengadukan sebesar 50 rpm, komposisi nutrisi ragi, dan bahan utama (molases) yang digunakan. Dari hasil penelitian didapatkan nilai densitas yang paling mendekati fuel grade densitas bioetanol yaitu sebesar 0,808 gr/mL pada saat menggunakan EM4 sebanyak 17 mL. Namun jika dilihat dari kadar bioetanol yang dihasilkan, hasil yang paling optimum justru terjadi pada saat penambahan ragi sebanyak 13 gram dengan kadar bioetanol sebesar 80 %. Sedangkan untuk nilai kalor yang dihasilkan, hasil yang paling optimum tejadi pada saat menggunakan EM4 sebanyak 17 mL dengan nilai kalor sebesar 8584,364 cal/gr.

Abstract

Dalam era digital saat ini, pengolahan data berbasis web telah menjadi kunci utama dalam memfasilitasi berbagai jenis aplikasi dan layanan online. Dengan pertumbuhan pesat volume data yang dihasilkan setiap hari, diperlukan rekomendasi teknis yang tepat untuk mengelola data secara efisien, aman, dan efektif. Tulisan ini bertujuan untuk menyajikan serangkaian rekomendasi teknis untuk pengolahan data berbasis web yang mencakup beberapa aspek kunci, termasuk infrastruktur teknologi, alat pengolahan data, keamanan informasi, dan skalabilitas. Pertama, dalam hal infrastruktur teknologi, penerapan arsitektur berbasis cloud menjadi sangat penting. Menggunakan layanan cloud memungkinkan skalabilitas yang mudah disesuaikan dengan kebutuhan, serta memberikan fleksibilitas dalam manajemen dan alokasi sumber daya. Selanjutnya, pemilihan alat pengolahan data yang tepat juga krusial. Platform seperti Apache Hadoop dan Apache Spark dapat digunakan untuk pemrosesan data besar-besaran secara efisien, sedangkan alat manajemen basis data seperti MySQL atau MongoDB cocok untuk penyimpanan dan pengambilan data yang cepat dan andal. Kemudian, dalam hal keamanan informasi, penerapan praktik-praktik terbaik dalam enkripsi data, otentikasi pengguna, dan kontrol akses menjadi sangat penting. Penggunaan protokol HTTPS untuk mengamankan komunikasi antara klien dan server, serta penerapan mekanisme otentikasi ganda, dapat meningkatkan tingkat keamanan keseluruhan sistem. Terakhir, skalabilitas merupakan faktor penting yang harus dipertimbangkan dalam pengolahan data berbasis web. Arsitektur yang dirancang dengan baik harus dapat mengakomodasi peningkatan volume data dan beban kerja tanpa mengorbankan kinerja atau ketersediaan layanan. Dengan menerapkan rekomendasi teknis ini, organisasi dapat memastikan bahwa pengolahan data berbasis web mereka berjalan dengan lancar, efisien, dan aman. Ini akan membantu mereka untuk tetap kompetitif di pasar yang semakin kompetitif dan memenuhi tuntutan pengguna untuk pengalaman online yang lebih baik dan lebih responsif.

Abstract

This study was conducted to investigate the effect of polypropylene residue on heated palm oil against histopathological changes of small intestine on male white rat (Rattus norvegicus) wistar strain. Eighteen male white rats divided into three groups and were administered via peroral gavage with different treatments for five weeks. The treatment were Control (84 grams palm oil), P1 (84 grams palm oil with 2.3 grams plastic), and P2 (84 grams palm oil with 6.81 grams plastic). The histopathological changes of small intestine were examined by using Barthel Scoring method was analysed using Kruskal Wallis and continued with Mann-Whitney test. The result showed that were significant difference (p<0.05) between treatment groups. The worse damage of polypropylene plastic residue was 6.81 grams.

Abstract

The aim of this research was to know histopathological changes of kidney of broiler chicken exposed to chronic heat stress. Twenty broilers were divided randomly into 2 groups, 10 broilers each are being exposed to chronic heat stress for 21 days. The first 21 days were the adaptation period in a chamber with temperature 24-28o C and humidity 40-55%. After 21 days, continue with exposure to heat stress in a chamber with temperature 36-40o C and humidity 50-65% in 8 hours per day. After exposed to chronic heat stress, kidney tissues were processed, and kidney tissue histopathological changes were evaluated by using the Klopfleisch modified scoring method. The data was analyzed by Mann – Whitney Test. The result of this research showed that chronic heat stress exposure causing the presence of degeneration of tubular epithelial cell, necrosis of tubular epithelial cell, necrosis of glomerular and interstitial infiltration. From the analysis data the overviewof multiparametric showed that when control group compared with the treatment group showed significantly difference (p<0.05).

Abstract

The aimed of this study is to know malaricidal ability of nanoparticle juwet (Syzygium cumini) leaf extract as adjuvant therapy on liver histopathological of mice (Mus musculus) which infected by Plasmodium berghei. This research uses 30 mice which are divided into six treatment groups namely K0 (not infected without treated), K+ (infected without treated), K1 (infected and treated with chloroquin), K2 (infected and treated with juwet leaf extract), P1 (infected and treated with juwet leaf extract nanoparticle) and P2 (infected and combination treated with chloroquine and juwet leaf extract nanoparticle) which infected by 1x105 in 0.2 ml of Plasmodium berghei. The data were analyzed by Kruskal Wallis using SPSS and followed with Mann-Whitney test. This research result showed there was significant difference (p < 0.05) between K1 and P2, but did not showed significant difference (p > 0.05) with K+, K2 and P1. Based on this research, it could be concluded that nanoparticle juwet (Syzygium cumini) leaf extract as adjuvant therapy estimated can increase malaricidal ability in degeneration, necrosis, portal inflammation, Kupffer cell hyperplasia, sinusoidal congestion, and hemosiderosis in mice liver which infected by Plasmodium berghei.

Abstract

In Indonesian education, the imperative challenge of cultivating robust character among the youth has surfaced prominently over the past decade, recognizing character's pivotal role in a nation's success trajectory. Innovative strategies, including the early integration of religious character values within educational settings like scout activities, become crucial responses to this challenge. Scout activities, renowned for their holistic approach to character development, serve as critical platforms in moulding religious character among students. This research aims to achieve three primary objectives: identifying embedded religious character values within Scout activities, exploring implementation methodologies, and investigating facilitating or hindering factors. The study navigates the intricate dynamics of religious character integration through a qualitative lens and employs semi-structured interviews, non-participant observation, and documentation analysis. The findings underscore the significance of rituals, notably communal prayers, as fundamental avenues for instilling religious values alongside activities promoting environmental stewardship deeply rooted in Islamic teachings. By elucidating the multifaceted role of Scout activities in nurturing religious character, this study contributes to the discourse on character education, offering insights for educators and policymakers to strengthen the moral fabric of future generations. Keywords: Religious Character Values, Scout Activities, Religious Character Integration
