ANALISIS KUAT TEKAN BETON NORMAL MENGGUNAKAN AGREGAT LOKAL KABUPATEN SARMI DENGAN VARIASI AIR PERENDAMAN

Introduction

Analisis kuat tekan beton normal menggunakan agregat lokal kabupaten sarmi dengan variasi air perendaman. Pelajari analisis kuat tekan beton normal menggunakan agregat lokal Kabupaten Sarmi. Temukan pengaruh variasi air perendaman terhadap kekuatan dan kualitas beton.

Abstract

Penyelidikan tanah yang biasa digunakan di Indonesia dalam mendesain pondasi adalah pengujian CPT (Cone Penetration Test) dan pengujian SPT (Standard Penetration Test). Penyelidikan sondir (Cone Penetration Test/ CPT) bertujuan untuk mengetahui perlawanan penetrasi konus dan hambatan lekat tanah yang merupakan indikasi dari kekuatan daya dukung lapisan tanah dengan menggunakan rumus empiris. Sedangkan Standart Penetration Test (SPT) bertujuan untuk mendapatkan nilai N-value sebagai nilai kerapatan relatif dari suatu lapisan tanah yang diuji dan mendapatkan gambaran lapisan tanah berdasarkan jenis dan warna tanah melalui pengamatan secara visual. Hasil penelitian nilai tahanan konus 320 qc pada kedalaman 5.3, pengujian SPT dengan total kedalaman 30meterberada pada nilai NSPT 34, pda kedalaman 5 – 6 adalah transisi dari perlapisan lempung berpasir ke pasir kerikil, ini yang Membuat penetrasi ujung konus hanya mencapai kedalaman 5meter, jida ditarik pada korelasi nilai kekuatan tanah dengan N-SPT di 6meterdengan nilai 34 sudah masuh kategori jenis tanah keras, hal ini sebanding dengan nilai sondir di atas 250 qc.

Review

The submitted manuscript, titled "ANALISIS KUAT TEKAN BETON NORMAL MENGGUNAKAN AGREGAT LOKAL KABUPATEN SARMI DENGAN VARIASI AIR PERENDAMAN," purports to investigate the compressive strength of normal concrete using local aggregates from Sarmi Regency, with variations in water immersion. However, the accompanying abstract presents a complete departure from this stated focus. Instead, it delves exclusively into geotechnical engineering topics, specifically discussing Cone Penetration Tests (CPT) and Standard Penetration Tests (SPT) for foundation design, including cone resistance, soil adhesion, N-values, and soil layer characteristics. This fundamental discrepancy between the title and the abstract raises significant concerns about the coherence and content of the paper. The abstract itself, while detailed in its description of CPT and SPT methodologies and findings (e.g., cone resistance of 320 qc at 5.3m, NSPT value of 34, transition from sandy clay to gravelly sand, classification as hard soil), provides absolutely no information relevant to concrete technology, aggregate properties, or the effect of water immersion on concrete strength. It reads as a summary of a soil investigation report, discussing empirical formulas for bearing capacity and visual observations of soil types. Consequently, it fails entirely to address the stated objectives of the title, making it impossible to ascertain the paper's actual scope, methodology, or contributions regarding concrete analysis. Given this severe mismatch, it is impossible to provide a meaningful review of the paper as a unified submission. The current state suggests either an incorrect abstract has been provided for the given title, or the title itself is entirely misrepresentative of the paper's true content. For this submission to be considered, immediate and substantial revision is required. The authors must either supply an abstract that accurately reflects the concrete analysis described in the title, or a new title that aligns with the geotechnical investigation detailed in the abstract. Without this crucial correction, the paper, as presented, cannot be evaluated for publication due to its lack of internal consistency.
