Aggregate from the Plasma River in North Luwu Regency has been widely used by the local community for construction, but there has been no research assessing the quality of aggregate in the construction sector. The research was carried out to determine the mechanical properties of compressive strength, split tensile strength, flexural strength and modulus of elasticity. This research took place in the structure and materials laboratory, Civil Engineering study program, Paulus Indonesian Christian University using the SNI 7656 – 2012 method, test objects in the form of cylinders (Ø 15 cm × height 30 cm), and blocks (60 cm × 15 cm × 15 cm). The compressive strength of the concrete was tested at the ages of 3, 7, 21 and 28 days and the split tensile strength, flexural strength of the concrete and modulus of elasticity were tested at the age of 28 days. From the research results, with a design quality of 25 MPa and 32 MPa, Plasma River aggregate is suitable for use in concrete mixtures.

The Radda River has aggregates with non-uniform grain distribution, clean, and visually seen with clear river flow. However, it is not yet known whether the Radda River aggregate can be used as structural concrete. This study was conducted to determine the compressive strength, flexural strength, splitting tensile strength of concrete and modulus of elasticity of concrete using aggregates from the Radda River. This study used the SNI 7656-2012 concrete design method with concrete quality f'c 25 MPa and 32 MPa through slump test on 28-day-old concrete. The average splitting tensile strength value of f'c 25 MPa concrete is 3.017 MPa. The average splitting tensile strength value of f'c 27 MPa concrete. The average flexural strength of f'c 25 MPa concrete is 3.759 MPa. The average flexural strength of f'c 32 MPa concrete is 4.176MPa. The results of the elastic modulus test for quality f'c 25 Mpa are 18,713.811 MPa. Theoretical value = 4700 x √25 = 23,500 MPa. The results of the elastic modulus test for quality f'c 32 Mpa are 27673.21667 Mpa. Aggregates from the Radda River can be used to achieve a quality of 25 MPa and 27 MPa using a material composition of 32 MPa.

This study uses cassava peel ash as a cement additive in concrete mixtures. As an important crop in many tropical countries, cassava produces a lot of waste during its processing, mostly in the form of cassava peels. One interesting material is cassava peel ash from cassava processing which is added to concrete. The purpose of this study was to determine the effect of cassava peel ash (AKS) addition in varying amounts to cement, namely 0%, 2%, 4%, and 6% on the compressive strength, split tensile strength, and flexural strength values of concrete mixtures. The mix design method uses SNI 7565:2012, fresh concrete testing uses SNI 1973:2008, compressive strength SNI 1974:2011, split tensile strength SNI 2491:2014, and flexural strength of concrete using SNI 4431:201. This research was conducted in the Concrete Laboratory of Civil Engineering of Universitas Kristen Indonesia Paulus. Based on the weight of cement, the amount of cassava peel ash used varied from 0%, 2%, 4%, and 6%. The compressive strength that meets the plan quality is found in variations of 0, and 2%, for split tensile strength and flexural strength, the variation in the addition of AKS values decreases. Concrete quality decreased with increasing AKS variation.

Concrete is one type of construction material that is generally used for building projects, bridges, roads, and other buildings. The Walanae River in Wajo Regency is one of the rivers that produces materials in the form of aggregate used by the local community, but there is no certainty that the aggregate can be used as a concrete mixture. The formulation of the problem in this study is based on the background that has been described, namely, whether the characteristics of concrete using the aggregate of the Walanae River in Wajo Regency are qualified as concrete construction materials. To conduct laboratory tests on concrete samples using aggregate from the Walanae River, Wajo Regency to determine compressive strength, tensile strength, bending strength, and modulus of elasticity. Testing of 25 MPa and 30 MPa plan quality samples. The test pieces used were 42 samples, compressive strength 24 samples, tensile strength 6 samples, bending strength 6 samples, and elastic modulus 6 samples. Based on the results of the 28-day concrete testing research for 25 MPa quality, achieving the planned quality was 25,455 MPa. The results of the 28-day concrete test for 30 MPa quality did not reach the planned quality obtained 27,152 MPa. Aggregate from the Walanae River can be used effectively in the production of concrete of a quality suitable for the structure.

Siswa SD Frater Bakti Luhur memiliki 844 siswa yang mana tempat tinggal mereka tidak semuanya berada dekat dengan sekolah. Selain itu, SD Frater Bakti Luhur yang terletak di ruas jalan yang memiliki volume kendaraan dan kecepatan tinggi sangat berisiko terhadap terjadinya konflik antar kendaraan atau kendaraan dan pejalan kaki. Tujuan dari kegiatan ini untuk meningkatkan keselamatan berlalu lintas pada siswa melalui penambahan pemahaman tertib berlalulintas dan kelengkapan informasi keselamatan lalu lintas di sekitar sekolah. Metode yang digunakan adalah analisis situasi awal dari mitra, mendesain model inovasi, edukasi terhadap siswa, penerapan teknologi, pendampingan dan evaluasi, serta monitoring keberlanjutan kegiatan. Hasil dari kegiatan ini berupa peningkatan pemahaman siswa akan keselamatan lalu lintas baik sebagai pejalan kaki maupun saat berada di kendaraan. Hasil kegiatan menunjukkan peningkatan pemahaman siswa sebesar 35% berdasarkan perbandingan pre-test dan post-test. Selain edukasi, tim juga memasang rambu peringatan, warning light, serta menyediakan pocket bookkeselamatan. Diharapkan keberlanjutan dari kegiatan ini agar dapat melibatkan orang tua untuk lebih memahami kesalamatan lalu lintas terutama saat berkendara dan berjalan kaki bersama anak di jalan raya.

Setiap titik persimpangan menggabungkan pengembangan lalu lintas yang konstan dan lalu lintas pertemuan setidaknya satu area konvergensi. Penelitian ini bertujuan untuk mengetahui kondisi lalu lintas pada simpang dan untuk mengatasi derajat kejenuhan dan tundaan pada simpang ini. Hasil perhitungan kapasitas berdasarkan PKJI 2014 yaitu C 2730 skr/jam. Penentuan nilai kapasitas simpang meliputi kapasitas dasar (Co) dengan nilai 3200 skr/jm, faktor koreksi lebar pendekat dengan nilai sebesar 0,98, faktor koreksi median jalan minor dengan nilai 1, faktor koreksi ukuran kota sebesar 1,00, faktor hambatan samping dengan nilai 0,93, faktor koreksi belok kiri dengan nilai 1,06, faktor koreksi belok kanan dengan nilai 0,96, dan faktor koreksi jalan arus minor (FMI) dengan nilai 0,92 dan nilai peluang antrian berkisar antara PA = 22,23 % - 72,53 %. Dari analisis simpang dapat disimpulkan bahwa hambatan pada simpang tak bersinyal antara Jl. Poros Makassar-Maros dengan Jl. Poros Kariango diakibatkan tidak adanya rambu lalu lintas yang mengatur setiap kendaraan yang melewati simpang tersebut. Nilai derajat kejenuhan pada simpang tak bersinyal ini sebesar 0,74 dan nilai tundaan simpang yaitu 12,77 det/skr.
