Pemanfaatan Kulit Kemiri Sebagai Bahan Subtitusi Agregat Halus Dalam Pembuatan Paving Block
Get PDFÂ Â Â Â Â Beton adalah bahan konstruksi yang umum digunakan dalam berbagai proyek konstruksi, termasuk pembuatan paving block. Campuran beton standar melibatkan agregat kasar, agregat halus, semen, dan air. Namun, inovasi dalam bahan tambahan beton terus berkembang untuk meningkatkan kualitas dan kinerja beton. Salah satu bahan tambahan yang menarik adalah kulit kemiri, yang dikenal memiliki struktur keras yang berbentuk menyudut. Kulit kemiri memiliki potensi untuk mengisi rongga-rongga pada beton dan meningkatkan daya serap beton. Penelitian ini bertujuan untuk menginvestigasi pengaruh penambahan kulit kemiri dalam campuran beton terhadap sifat daya serap dan kekuatan paving block beton. Studi ini mencakup lima variasi dengan persentase penambahan kulit kemiri yang berbeda, yaitu 0%, 15%, 20%, 25%, dan 30%. Masing-masing variasi dianalisis melalui pembuatan 70 benda uji berbentuk persegi panjang dengan ukuran 8 cm x 10,5 cm x 21 cm, yang diuji pada usia 28 hari. Hasil penelitian menunjukkan bahwa penambahan kulit kemiri dalam campuran beton mengakibatkan penurunan nilai kuat tekan paving block beton. Penurunan ini mungkin disebabkan oleh struktur berongga kulit kemiri yang mengurangi kekuatan beton. Namun, hasil yang menarik adalah peningkatan daya serap beton dengan penambahan kulit kemiri. Kulit kemiri yang berongga dapat menyerap air dengan baik, yang dapat mengurangi risiko genangan air pada permukaan paving block saat hujan. Penelitian ini menunjukkan bahwa penggunaan kulit kemiri sebagai bahan tambahan dalam beton memiliki potensi untuk meningkatkan daya serap, meskipun dengan sedikit pengorbanan dalam hal kekuatan. Oleh karena itu, penambahan kulit kemiri dapat menjadi pertimbangan dalam proyek konstruksi di mana daya serap dan resistensi terhadap genangan air menjadi faktor penting. Namun, diperlukan penelitian lebih lanjut dan uji lapangan untuk memahami implikasi praktis penggunaan kulit kemiri dalam aplikasi konstruksi yang berbed
Compound Critiquing Approach for Laptop Recommendation in Conversational Recommender System Using Collaborative Filtering
Get PDFThis study proposes a method for laptop recommendation in a conversational recommender system (CRS) by integrating collaborative filtering with the Apriori algorithm. The CRS interacts with users to help them find laptops that match their preferences, allowing them to provide feedback or critiques on the recommendations. This research emphasizes the use of compound critiques, which allow users to express preferences on multiple attributes at once, leading to more personalized recommendations. The Apriori algorithm identifies frequent itemsets from these critiques, which are then used to iteratively update recommendations. Evaluation results show that the High Support (HS) strategy, which focuses on commonly preferred features, produces more efficient recommendations, with a shorter average session duration of 38.01 seconds compared to the Low Support (LS) 41.30 seconds and Random (RAND) 50.49 seconds. This approach improves the recommendation process by better aligning with user preferences, which in turn improves interaction efficiency. @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536869121 1107305727 33554432 0 415 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-469750017 -1073732485 9 0 511 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; text-align:center; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; mso-ascii-font-family:Calibri; mso-hansi-font-family:Calibri; mso-font-kerning:0pt; mso-ligatures:none; mso-ansi-language:EN-US;}div.WordSection1 {page:WordSection1;
