Concrete surface temperature changes on active thermography testing process using a halogen lamp will occur in a relatively short time. These changes are very useful in the image interpretation process which relies on changes in thermal contrast to determine the internal conditions of reinforced concrete. This research aims to determine the time interval dominance concrete surface temperature changes due to changes in object distance to the heat source as the excitation source of heat. Tests carried out in the room, so that the concrete surface temperature changes due to the effects of wind are considered small. Measurement of the temperature of the concrete surface due to the heating and cooling process using thermocouples and thermography methods. Halogen lamps are used as a source of heat excitation placed at various distances (dobj), namely 20 cm; 30 cm and 40 cm. The distance between the halogen lamp axles in this study was 30 cm. The dimensions of the test object were used 10 cm x 10 cm x 15 cm with a concrete quality of 20 MPa. The frequency percentage is analyzed according to the amount of data with the same time interval for the change in surface temperature at each distance of the specimen from the heat source. The results showed that the change in the distance of the specimen to the heat source up to 40 cm had a quite small difference, but the increase in the distance between the test object and the heat source tended to decrease the dominance of changes in the temperature of the concrete surface. The average dominance of changes in the temperature of the concrete surface is almost above 75% of the temperature change occurs at the smallest interval of the measuring instrument used, namely 1 second using a thermocouple and 0,133 seconds using the thermography method. The highest percentage shows that changes in surface temperature often occur in the range of time intervals. So based on this analysis without reviewing aspects of the distribution pattern of the data, can be concluded that the surface temperature testing of concrete by using active thermography in the room had to use measuring devices that can record temperature changes every interval of 0.133 seconds. This shows that the change in the temperature of the concrete surface during active thermography testing, the setting of the test instrument for measuring temperature changes is used in that time interval.

The construction industry is an important thing to support the development of a country. In concrete construction, quality, strength, and durability of concrete are the main requirements of all. In urban tropical countries, carbonation is one of the essential factors that affect the durability of concrete, and it may cause corrosion of reinforced steel in concrete. Therefore, high strength self-compacting concrete may be expected as the solution, improved by pozzolanic additions, metakaolin with substitution dosage at 10%; 12,5%; 15%; 17,5%; and 20%. This study purposed to determine the effect of metakaolin and its optimum dosage to improve high strength self-compacting concrete quality on its carbonation rates. This study was done by using experimental methods. It needs a plain cylindrical concrete with 75 mm diameter and 150 mm height, and testing by SNI 03-6468-2000, EFNARC 2002, and SEM-PUPR 25-2015. The carbonation test is done using accelerated laboratory carbonation in Structures and Materials Laboratory, Faculty of Engineering, Universitas Sebelas Maret by soaking the specimens in a 4% carbonate solution for 15 days, 37 days, and 51 days, proceeded by splitting using CTM, and spray it using a 1% phenolphthalein indicator to determine its carbonation depth. Based on the results, metakaolin might improve concrete quality by reducing its carbonation rates by 15% substitution dosage of cement content, with a nominal atmospheric carbonation coefficient 3,71 mm/year½, reduced 44,41% from HSSCC without metakaolin substitution. Metakaolin addition might reduce fresh concrete's workability and fulfill self-compacting concrete requirements specified by EFNARC 2002.

Plasticine is an artificial material made from solids such as gypsum, lime, mixed with petroleum jelly or micro wax and acid fat. The properties of plasticine are likely similar to natural clay and is influenced by oil content. The information about mechanical properties of plasticine is still very rare, and as such the study on it is riquired and must be conducted intensively. The preliminary laboratory study has been conducted to understand the behaviour of plasticines. Microwax and petroleum jelly based plasticines were utilised with the variation of oil content, whereas kaolin clay with the variation of water content is utilised as a reference material. The study is focusing on the stress-strain behaviour for both microwax and petroleum jelly based plasticines compared to the stress-strain behaviour of kaolin clay. This paper reports the result of preliminary investigation regarding the use of plasticine as an alternative artificial material for substitution of clay in soil modeling. Some engineering properties from unconfined compression strength (UCS) test and hand penetrometer are shown. The result indicates that the stress-strain behaviour of plasticine resembles the stress-strain behaviour of kaolin clay. The plasticine is suitable as a substitute cohesive material and it has a potential to be utilised for geotechnical material modelling in the future.

Walkability Index (WI) is a method to assess the walkability level on pedestrian facilities with the main components of: safety and security, convinience and attractiveness, as well as government policies. Generally, this method is utilized to review the pedestrian facilities walkability in urban areas, particularly in CBD (Central Business District) which is the hub for activities center, such as economic, business, education, healthcare, transit to tourism areas. The rapid development of activities leads to the increasing number of visitors in those areas, such as on Jalan Slamet Riyadi, Surakarta. This condition needs to be balanced with the availability of adequate facilities and infrastructure, one of them is the sidewalks to facilitate the pedestrian movement from one place to another. Indonesia did not have any assessment criteria for sidewalks in terms of scoring even though some variables on WI have already existed in the Circular Letter of the Minister of Public Works and Public Housing 02/SE/M/2018 on the Guidelines for Pedestrian Facility Planning. This paper presents the recommendation of assesment and category based on the regulation in Indonesia. It is expected to benefit the determination of priority on pedestrian facility handling in the field. Literature study as the foundation of this paper attempts to accomodate the pedestrian facility variables contained in the regulation of Indonesia using the scoring method with several recommendations in the category of handling, with the basis of WI analysis method. The results of the analysis show that there are 3 variables that need to be considered more in the planning criteria for sidewalk in Indonesia that affect the determination of handling recommendation including the supporting and additional facilities, facilities for disabled pedestrians, and the needs of wide space for pedestrians.

Longsor aliran adalah gerakan spasial yang terjadi terus menerus akibat bergeraknya permukaan tanah biasanya berjarak dekat dan terjadinya tidak terlalu lama. Gradasi longsoran aliran tergantung pada intensitas hujan, jenis tanah dan vegetasi sedangkan arah mobilitas tergantung dari kemiringan lereng dan jenis tanah permukaannya. Jenis tanah yang mudah jenuh akibat hujan dengan intensitas tinggi dan singkat di lereng menyebabkan lapisan tanah tergerus akibat berat sendiri secara cepat menuju lembah, hal inilah yang menyulitkan bagi penduduk untuk menghindar dan mengungsi. Kasus tersebut perlu dilakukan analisis dan kajian teknis tentang pengaruh nilai derajat kejenuhan tanah yang menimbulkan ancaman longsor bahan rombakan. Pengamatan dilakukan dengan sampel borehole dan Geolistrik dilakukan Desa Abang Batu Dinding, Kintamani, morfologi permukaan adalah perbukitan, jenis tanah pada kedalaman rata-rata 1-1,5 m adalah lanau berpasir, dan batuan dasar berupa batuan breksi vulkanik. Analisa hidrologi dimodelkan berdasarkan poligon thiessen dimana curah hujan efektif rata-rata pada 10-50 tahun sebesar 238 mm/hari. Nilai tegangan air pori negatif bertambah dari 35 kPa-72,44 kPa dalam pori-pori tanah masih terdapat air yang dapat menjaga ikatan butiran tanah pada saat derajat kejenuhan rendah sekitar 40% dan selanjutnya naik sampai 78,46%. Pada penelitian ini pada derajat kejenuhan 40% sampai 56% nilai kuat geser tanah meningkat dan selanjutnya kuat geser tanah mengalami penurunan sampai 37,62o dengan derajat kejenuhan 78,46%. Perubahan yang cepat pada permukaan tanah yang minim vegetasi akan menimbulkan erosi dipermukaan tanah, pada kondisi spasial dengan ketebalan tanah 1-1,5 m akan menyebabkan longsor rombakan atau debris.

The development of technology construction has reached a period of caring for the environment. Many things been developed to support environmentally friendly construction. Itcan be started from the use of a mixture of natural ingredients into a mixture of construction materials. Concrete is a construction material that is often used in Indonesia, given its ease, price, and durabilityAlong with the development of the concrete periods has experienced many advances, one of which is in the drafting of a combined mix of making concrete, and to supporting environmentally friendly concrete, a mixture of natural materials are used as one of the making material of concrete.South Sumatra is one of the islands in Sumatra, which has an abundant plantation of rubber. The large number of rubber plantations makes rubber waste more and more, one of which is rubber seeds. Therefore it is necessary to treat rubber seed waste in order to reduce the amount of rubber seed waste and can be used to improve the economy of the surrounding community. The rubber itself has many advantages in the industrial field. Utilization of rubber has been widely used, but no one has used rubber seeds as an aggregate substitution material in making a concrete without other chemicals. Therefore this research will discuss the rubber seed mixture as a substitute for coarse aggregate. The material used to make concrete is portland type I cement, coarse and fine aggregate from the Tanjung Raja area, and the rubber seeds used are from the Sembawa area. Coarse aggregate substitution using a mixture of rubber seeds 5%, 10%, 15%, and 20% were tested during the age of concrete of 7 days, 14 days, and 28 days.. The compressive strength of rubber seed substitution with a percentage of 5% shows the most significant compressive strength value of 19.33 Mpa. From the test results of this study it can be concluded that the greater the use of rubber seeds, the lower the compressive strength.
