“…The recent scientific literature provides some preliminary studies on the development and characterization of new eco-sustainable cementitious mixes, based on recycled aggregates, potentially suitable in the production of paving elements. Limantara et al [24] developed cement-based mix designs by using coconut fibers and crushed shells as aggregates in different ratios, demonstrating compliance between strength and permeability test results with the Indonesian technical requirements for parking areas. Agyeman et al The recent scientific literature provides some preliminary studies on the development and characterization of new eco-sustainable cementitious mixes, based on recycled aggregates, potentially suitable in the production of paving elements.…”

Limantara et al [24] developed cement-based mix designs by using coconut fibers and crushed shells as aggregates in different ratios, demonstrating compliance between strength and permeability test results with the Indonesian technical requirements for parking areas. Agyeman et al [25] evaluated the potential of using grounded plastic waste (polyethylene bags, sachet water bags, and bubble packaging films) as a binding material to totally replace the cement, re-vealing physical and mechanical performances in agreement with recommended values for non-traffic applications (walkways, footpaths, and landscapes) in Ghana.…”

The use of waste materials as alternative aggregates in cementitious mixtures is one of the most investigated practices to enhance eco-sustainability in the civil and construction sectors. For specific applications, these secondary raw materials can ensure adequate technological performance, minimizing the exploitation of natural resources and encouraging the circular disposal of industrial or municipal waste. Aiming to design and develop lightweight paving blocks for pedestrian or very light-traffic purposes (parking area, garage, sidewalk, or sports surfaces), this paper presents the material characterization of rubberized cement mortars using ground waste tire rubber (0–1 mm rubber powder and 1–3 mm rubber granules) to totally replace the mineral aggregates. Considering recommended requirements for concrete paving members in terms of mechanical strength, water drainage performance, acoustic attenuation, and dynamic and energy absorption behavior, a comprehensive laboratory testing is proposed for five different formulations varying the sand-rubber replacement level and the proportion ratio between the two rubber fractions. Tests highlighted positive and promising results to convert laboratory samples into pre-cast members. The “hot” finding of the work was to prove the feasibility of obtaining totally rubberized mortars (0 v/v% of sand) with suitable engineering performance and enhanced eco-friendly features.

“…The researchers demonstrated the mechanical properties of UHP-FRC and found that fibres increased stress resistance. Similarly, other researchers replaced coarse, fine aggregates with fibres to enhance the mechanical properties of concrete [85][86][87]. Research has also indicated that FRC can improve post-cracking behaviour in comparison with standard concrete [88,89].…”

Sistem daya tahan tubuh yang dimiliki oleh balita lebih lemah daripada orang dewasa membuat balita lebih rentan terserang penyakit, diantaranya penyakit alergi. Alergi adalah suatu reaksi hipersensitivitas yang dipengaruhi oleh mekanisme imunologi, yang dapat memengaruhi hampir semua jaringan tubuh dan memunculkan gejala klinik sesuai dengan organ yang terkena, alergi biasanya terjadi pada kulit manuasia. Kulit adalah organ terbesar dari tubuh manusia yang menjadi pertahanan pertama tubuh dari serangan bakteri dan virus. Untuk itu, orang tua harus memberikan perhatian lebih kepada balita karena dengan kondisi kesehatan yang kurang baik tentu akan sangat berpengaruh pertumbuhan anak. Kurangnya tenaga ahli dibidang kulit sehingga dibutuhkan sebuah sistem pakar yang mampu menyamai dengan ahli pakar dengan harapan dapat membantu orang tua agar mengetahui tentang penyakit alergi kulit pada balita lebih awal. Adapun metode yang digunakan untuk mengidentifikasi jenis penyakit alergi kulit pada balita yaitu dengan menggunakan metode Certainty Factor dimana metode Certainty Factor menunjukan nilai kepastian dari suatu fakta yang belum pasti dan memperoleh tingkat akurasi 100% dari pengujian 8 data pasien, sehingga dengan adanya metode Certainty Factor dapat digunakan untuk mengetahui jenis penyakit kulit yang diderita oleh balita.
