Abstract

Kondisi jalan yang menikung curam serta terdapat banyak kerusakan juga menjadi salah satu factor penyebab terjadinya kecelakaan di Jalan Raya Jepara-Bangsri Km 05 Desa Mambak ini, selain itu mayoritas pengguna jalan ini adalah truck bermuatan besar serta container yang mana sering menjadi penyumbang kerusakan jalan. Berdasarkan beberapa factor yang telah dijelaskan diatas, maka perlu diadakan penelitian analisis kecelakaan lalu lintas di Jalan Raya Jepara-Bangsri Km 05 Desa Mambak yang mampu menyediakan sebuah sistem dan cara yang dapat menjadi evaluasi terhadap kecelakaan lalu lintas yang sering terjadi di Jalan Raya Jepara-Bangsri Km 05 Desa Mambak ini. Metode yang digunakan dalam analisa ini adalah metode Kuantitatif Descriptive atau survey lapangan yang mana akan digunakan untuk mengevaluasi Geometrik jalan, nilai accident rate (tingkat kecelakaan), accident cost (biaya kecelakaan) dan juga menetukan titik Black Spot (daerah rawan kecelakaan).

Abstract

Jalan Raya Jepara - Bangsri merupakan Jalan Provinsi dan termasuk jalan yang mengalami kerusakan jalan yang cukup parah. Sehingga diperlukan adanya analisis yang mengkaji tentang beberapa jenis kerusakan jalan tersebut serta penanganan yang sesuai dengan kerusakan jalan tersebut. Berdasarkan hasil analisis yang didapat jenis kerusakan yang terjadi pada ruas Jalan Raya Jepara-Bangsri KM 16 s/d KM 18 jika ditinjau dengan metode PCI dan Bina Marga memiliki peresentasi kerusakan sebesar Retak buaya (38,75%), Retak Blok (17,39%), Retak Pinggir (8,89%), Lubang (17,49%), Tambalan (12,99%), Pengausan (10,89%), dan amblas (3,59). Untuk penilaian kondisi jalan dengan metode PCI diperoleh rata-rata sebesar 55,523 yang termasuk dalam kategori sedang (Fair), sedangkan untuk metode Bina Marga diperoleh rata-rata nilai urutan prioritas sebesar 7,2. Hasil dari keduanya memiliki jenis penanganan yang sama yaitu Pemeliharaan Rutin. Untuk menghindari kerusakan jalan yang semakin parah maka perlu adanya perhitungan mengenai rencana tebal lapis tambahan perkerasan lentur. Berdasarkan hasil jenis nomogram 3 dengan Ipt = 2,0 dan Ipo = 4 sehingga diperoleh tebal perkerasan laston AC-WC (lapis aus) tebal 7,5 cm, AC-BC (lapis antara) tebal 10 cm, dan Lapis pondasi Sirtu kelas A tebal 12 cm.

Pada penelitian yang telah di lakukan dengan variasi campuran 0%, 2,5%, 5%, 7,5%, 10% mengalami kenaikan dari umur 7 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 31,8 MPa, di umur 14 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 37,1 MPa, umur 28 hari kuat tekan tertinggi nya di variasi 10% dengan nilai 39,1 MPa, dikategorikan menurut SNI 03-0691-1996 masuk kedalam mutu B. Untuk penyerapan air nya mengalami pemadatan jadi penyerapan air nya menurun dari 0% ke 10% dengan nilai 3,393 – 3,192 dikategorikan menurut SNI 03-0691-1996 masuk kedalam mutu B karena nilai nya lebih dari 3%.

Abstract

Background: Cement is a key component in mortar production due to its calcium-rich composition, which plays an essential role in pozzolanic reactions. However, the extensive use of cement contributes to high carbon emissions and limestone exploitation. The incorporation of laterite stone powder as a partial cement replacement offers a potential alternative to enhance mortar performance while promoting sustainable construction practices. Aims: This study aims to evaluate the effect of laterite stone powder as a partial substitute for cement on the compressive strength and density of mortar. Methods: A quantitative experimental approach was employed through laboratory testing. Laterite stone powder passing a 200-mesh sieve was used as a partial cement replacement at substitution levels ranging from 0% to 10% by weight of cement. The mortar mixture was prepared with a cement-to-sand ratio of 1:3 and a water–cement ratio of 0.5. Compressive strength and density tests were conducted on 50 mm × 50 mm × 50 mm cube specimens at curing ages of 7, 14, 21, and 28 days. Result: The results showed that the highest compressive strength, reaching 20.33 MPa, was obtained at a 3% laterite stone powder substitution after 28 days of curing. Substitution levels exceeding 3% resulted in a gradual decrease in compressive strength, indicating a reduction in mortar performance at higher replacement ratios. Conclusion: The study concludes that laterite stone powder can be effectively utilized as a partial cement replacement in mortar at an optimum level of 3%. This substitution not only improves compressive strength but also contributes to sustainable construction by reducing cement consumption and minimizing limestone exploitation in Indonesia.

Abstract

Bamboo is a potential alternative material to replace wood and steel, offering several advantages such as favorable physical and mechanical properties, lightweight characteristics, high moisture tolerance, elasticity, and a significantly shorter growth cycle compared to wood. However, bamboo also has notable disadvantages, including low natural durability and vulnerability to powder-post beetle attacks. To address these issues, preservation treatments are recommended prior to use, although the type and duration of treatment may influence the physical and mechanical properties of bamboo, thereby affecting its quality. This study aims to determine the optimal treatment duration to enhance the tensile strength of bamboo through a simple and environmentally friendly preservation method, namely immersion in either freshwater or saltwater for varying durations (1 × 24 hours, 3 × 24 hours, and 14 × 24 hours), followed by tensile strength testing. The results indicated that the highest tensile strength was obtained with a treatment duration of 3 × 24 hours, with treated specimens exhibiting an increase in tensile strength ranging from approximately 10% to 30% compared to untreated samples. Furthermore, bamboo treated with saltwater demonstrated higher tensile strength than that treated with freshwater, suggesting that both treatment duration and type of preservative significantly affect tensile performance. It can be concluded that inappropriate treatment durations—either too short or too long—may lead to suboptimal tensile strength in bamboo.

Abstract

Fine aggregate plays a significant role in concrete mixtures because it constitutes approximately 60–75 percent of the total volume, meaning that its characteristics directly influence concrete quality. In the Ciayumajakuning region, Cimalaka sand (Sumedang) is more commonly used even though its logistical distance is farther compared to Ciputat sand (Indramayu); however, no scientific study has directly compared the two materials. This study aims to examine the material properties characteristics and the effect of using these two types of sand on the compressive strength of concrete with a design strength of f'c 25 MPa, as well as to assess the feasibility of Ciputat sand as a substitute for Cimalaka sand. The method applied was experimental using 24 cylindrical specimens measuring 15 cm × 30 cm, tested at the ages of 7, 14, 21, and 28 days in accordance with SNI 03-2834-2000. The material property test results indicate that Ciputat sand belongs to Zone 3 with a mud content of 3.0 percent (meeting the SNI requirement of =< 5 percent), while Cimalaka sand belongs to Zone 1 with a mud content of 7.28 percent (exceeding the SNI limit and therefore requiring washing). At 28 days, the average compressive strength values of the concrete were recorded at 26.138 MPa for Ciputat sand and 25.666 MPa for Cimalaka sand, both exceeding the target design strength of f'c 25 MPa. The insignificant difference in values indicates that the performance of both sands is relatively equivalent, suggesting that Ciputat sand has the potential to be used as a more logistically efficient alternative without compromising structural quality.
