The sontang-duri cross road is a causeway that is often traversed by large trucks. The problem that occurs is that the road construction has been destroyed, because this road has a subgrade of peat, where peat soil is considered to be less profitable soil if used as the basis of a road construction. Peat soil has low soil bearing capacity, high water content and high compressibility. The purpose of this study was to determine the percentage value of the California Bearing Ratio (CBR) peat soil stabilized using lime using variations of 5%, 10%, and 15%. The method used for this problem is to carry out chemical stabilization with the mixture of lime. From the results of the tests that have been carried out, the original soil CBR value of 95% maximum dry density was obtained at 1.40%. The addition of lime to peat soil with variations of 5%, 10%, and 15% increased the CBR value. The increase that reaches the requirements to be used as a road subgrade is in the variation of 15%, with a CBR value of 8%. The requirement to be used as a road subgrade is based on the bina marga specification of 6% so it can be concluded that the addition of lime for peat soil stabilization can increase the CBR value.

AbstractThe most noticeable change during the COVID-19 pandemic was that fewer people travel from one place to another unless it was very urgent. This was mainly driven by the government's instruction not to carry out activities outside the home except for vehicles transporting goods. The government appeal decreases public transportation operations and reduces the income of public transportation service providers. This study aimed to determine and analyze the impact of the COVID-19 pandemic on public transportation (passengers and goods) from Aceh Barat to Medan. The descriptive quantitative method was used in this research. Data collection was carried out through direct surveys and questionnaires, which were randomly distributed to public transport drivers (passengers/goods) at the passenger and freight terminals during working hours. The survey data were analyzed using multiple linear analyses with the help of SPSS software to observe the influence of the independent variable (X) on public transportation (passengers/goods) during the pandemic (Y). The results obtained from the analysis indicated that there are several equations obtained, the equation for passenger transportation: Y1 = 0.298 - 0.770X1 + 0.113X6 and the equation for freight transportation: Y2 = 0.113 + 0.546 X3 + 0.338 X6. From this equation, it can be concluded that there is a relationship between the amount of income (X1), travel time (X3), and expenditure costs (X6) on the impact on public transportation during the COVID-19 pandemic. Keywords— Impact of the COVID-19 Pandemic, Passenger Transport, Goods Transport

Pemilihan material dalam pembuatan beton sangat penting untuk mendapatkan mutu beton yang diinginkan. Banyak riset yang dilakukan untuk mengganti material (alam) beton dengan material lain seperti halnya penggunaan material limbah konstruksi (limbah beton). penggunaan material limbah konstruksi (limbah beton) sebagai salah satu alternatif yang cukup memiliki potensi untuk diteliti karena daur ulang beton (limbah beton) masih jarang di lakukan dan masih sedang banyak di uji coba. Untuk itu kami akan mencoba memanfaatkan penggunaan limbah beton sebagai pengganti agregat dalam pembuatan beton baru yang terbaik di mulai dari penentuan ukuran atau gradasi limbah beton sebagai pengganti agregat, yang mempunyai kuat tekan yang memenuhi. Berdasarkan permasalahan di atas maka peneliti ingin mencoba memanfaatkan penggunaan limbah beton untuk mengetahui bagaimana pengaruh gradasi limbah beton sebagai penganti bahan agregat kasar pasir dan kerikil terhadap kuat tekan beton. Berdasarkan hasil penelitian pemakaian limbah beton sebagai pengganti agregat kasar dan halus terhadap kuat tekan beton, dapat di simpulkan bahwa pemakaian limbah beton pasir kasar mempunyai nilai tekan lebih baik yaitu sebesar 15.377 Mpa di bandingkan dengan pemakaian limbah beton pasir halus yang sebesar 13.101 Mpa.

Lightweight concrete is concrete that has a specific gravity that is lighter than ordinary concrete. Lightweight concrete can be interpreted as concrete that has a volume weight between 1400-1850 kg/m3. The use of materials that have a light density in the concrete mix will reduce the overall weight of the concrete, thereby reducing the dimensions of the structure and can reduce structural loads, especially dead loads. Pumice or pumice is an aggregate that is classified as light aggregate. This type of stone is widely spread in the North Maluku region. In this study, pumice stone was used as a coarse aggregate for making concrete, the use of pumice as a coarse aggregate tends to reduce the compressive strength, so fiber fibers were used as an added material to the concrete mixture so that fiber concrete was obtained. . This study uses experimental methods, cylindrical specimens with 15 cm and height 30 cm for compressive strength testing, beam test specimens with a size of 15 cm x 20 cm x 120 cm for flexural strength testing. The reinforcement in the concrete beam is varied with variations of 2 reinforcement, 3 reinforcement and 4 reinforcement. The test results show that the use of palm fiber as an added material for the manufacture of lightweight concrete can increase the compressive strength of concrete by 11.70% against lightweight concrete without fibers. The addition of 4 reinforcement at the bottom of the beam tends to increase the capacity of the lightweight concrete beam by 3.28%.

Using Concrete-Filled Steel Tube (CSFT) as a column component provides many advantages over steel columns and reinforced concrete columns. Steel tube serve as reinforcement as well as formwork for concrete filler material. Besides, restrain effect of steel tube prevent crack in the concrete. The concrete-filler on steel tube prevent local buckling and increases the strength and stiffness of the column. The lack of experience and complexity of the beam-column connection system becomes an obstacle to use the CFST as a column. In addition, strength and stiffness of the connection system on CFST should be sufficient to endure the earthquake loads. This research purpose to find alternate connection of CFST column beams and also to know hysterestis behavior, strength, stiffness and pattern of connection collapse due to cyclic loading. There are two specimens in this research, continuous joint of beam-column steel tube with concrete filler (BKM-T) and continuous joint of beam-column steel tube without concrete filler (BKM-K). BKM-K as a comparator to show an increasing strength and stiffness due to the concrete core. Load cycle of specimens refer to ACI 374.1-05. The test results showed the average maximum load (Ppeak) of 32.59 kN on BKM-K increased to 34.08 kN on BKM-T. Elastic stiffness (Ke) at BKM-K of 0.78 kN/mm increased to 1.08 kN/mm on BKM-T. BKM-T also has a larger hysteretic loop than BKM-K. In addition, BKM-K and BKM-T adequate the strong column weak beam criteria with partial ductility.

Concrete is a building material consisting of a mixture of cement, water, fine aggregate, coarse aggregate in a certain ratio. With the number of buildings that use concrete, the demand for concrete increases, and the use of aggregate as a supporting material for concrete increases as well. Innovation in concrete-forming materials can be done by substituting substitute materials, either aggregates or other materials by utilizing the waste that is around us. One of the wastes that can be used around us is brick waste. From the above phenomenon, the researcher will innovate on the concrete constituent materials by utilizing waste bricks as a substitute for fine aggregate to find out how much the compressive strength of concrete is at the age of 7 days and 28 days. The effect of adding brick powder to the concrete mixture resulted in a decrease in the compressive strength of the concrete. The higher the percentage of brick powder added to the concrete mixture, the lower the compressive strength of the concrete will be
