Abstract

Sosialisasi terkait pemanenan air hujan merupakan langkah penting untuk mempromosikan konservasi sumber daya air. Metode ini melibatkan pengumpulan dan penyimpanan air hujan yang dapat digunakan untuk berbagai kebutuhan, seperti mencuci, menyiram tanaman, bahkan sebagai air minum dengan melewati proses penyaringan yang tepat. Masyarakat Desa Penfui Timur dipilih sebagai mitra karena melihat masyarakat yang sering mengalami kesulitan air bersih di saat musim kemarau sehingga harus membeli air dan memanfaatkan sumber air tanah. Sehingga melalui kegiatan ini masyarakat menjadi tahu keuntungan dalam menerapkan metode Rain Water Harvesting (RWH) diantaranya meningkatkan ketersediaan air, mengurangi banjir dan erosi, serta menjaga keberlangsungan lingkungan. Proses ini telah berhasil terlaksana dengan adanya pendidikan dan penyuluhan rutin kepada masyarakat, dukungan dari pemerintah, serta contoh langsung berupa pemasangan RWH pada tempat umum seperti sekolah dan kantor pemerintah untuk menunjukkan manfaat RWH secara langsung. Dengan sosialisasi yang efektif, masyarakat dapat memahami pentingnya pemanen air hujan sebagai solusi konservasi air yang berkelanjutan, meningkatkan penerimaan dan partisipasi dalam implementasinya.

Abstract

The Barito watershed, as one of the largest watersheds on the island of Kalimantan, has an upstream area that is close to the equator, while the downstream area is far from the equator. This makes it interesting to see climate variability, especially rainfall that occurs in the Barito watershed. The extreme rainfall indices R20mm and R50mm are used to see the spatial variability of rainfall events, while R1X and RX5 are used to see the temporal variability of rainfall that occurs in the Barito watershed. This research shows that the frequency of rainfall events from meteorological stations, PERSIANN satellites and GPM satellites occurs most frequently in the Upper Watershed area. However, rainfall trends have not shown significant results in the last 21 years between the upstream, middle and downstream watershed areas. This is influenced by the sloping and flat conditions of the watershed, resulting in rainfall intensity tending to occur evenly throughout the watershed. The results of the IDF analysis show that there are similarities between the rainfall intensity measured at the meteorological station and the PERSIANN satellite, which gives varying intensity values ​​over a short duration of less than 50 minutes.

Abstract

Cone Penetration Test (CPT) or sondir is a method designed to determine and test the strength of the soil layer. This sondir test has been carried out in Tunfeu Village, Nekamese District, Kupang Regency, East Nusa Tenggara to determine the resulting bearing capacity and determine the type of foundation that is suitable for the research location point. The soil investigation method is carried out by direct testing in the field using a sondir tool. Secondary data were obtained from several literature studies. Primary data obtained from sondir results at three predetermined location points. Data analysis used two parameters at each depth, namely the Conus Resistance Value (qc) in kg/cm2, and the total shear value (Tf) in kg/cm units. The two parameters above were recorded for every 20 cm interval where at point 1 the value of qc ³ 245 kg/cm2 is obtained at a depth of –11.60 m with a Tf 337.33 kg/cm. At point 2 the value of qc ³ 225 kg/cm2 is obtained at a depth of –21.20 m with a Tf 394 kg/cm. While at point 3 the value of qc ³ 235 kg/cm2 is obtained at a depth of –19.60 m with a Tf 548.67 kg/cm. Based on the results of the sondir above, the type of foundation that is suitable for the soil conditions in Tunfeu Village is a pile or deep foundation (bored pile).

Abstract

In this study, an analysis was conducted on the influence of the number of compaction impacts on the density of asphalt mixtures using the Marshall method on Hot Rolled Sheet Wearing Course (HRS-WC) Thin Asphalt Concrete (Lataston) mixture. The main objective of this research is to compare the compaction results between manual and electric methods. To achieve this, variations in the number of impacts were performed, namely 2 x 25, 2 x 40, 2 x 50, 2 x 60, and 2 x 75 impacts. The research results showed a significant difference between the manual and electric compaction methods in the observed Marshall parameters. Especially with 2 x 75 impacts, a noticeable difference was observed with a stability difference percentage of up to 2.505%. Therefore, it can be concluded that although the manual and electric compaction methods yield relatively similar results in terms of Void In Mix (VIM), Void In Material Aggregate (VMA), and Void Filled With Bitumen (VFB), there is a significant difference in stability, flow, and Marshall Quotient (MQ) parameters. This research has important implications in asphalt compaction practice and can be used as a guideline for selecting the most suitable compaction method to produce optimal quality asphalt mixtures.

Abstract

The hot mix asphalt-aggregate mixture in the construction of asphalt concrete roads generally consists of three layers: the base layer, intermediate layer, and surface layer placed on a granular subbase. One of the asphalt concrete layers is the Intermediate Layer, which is a hot asphalt mixture consisting of aggregate, asphalt material, and filler mixed at a central mixing plant. The resulting mixture is spread and compacted on the Aggregate Base Layer. The hot asphalt mixture is designed according to the General Specifications for Road and Bridge Construction by the Directorate General of Highways in 2018 (Revision 3) to ensure that the design assumptions regarding Asphalt Content, Air Voids, Stability, Flexibility, and Durability are in line with the planned traffic. Research results indicate differences in Marshall characteristics from Marshall test results for the Intermediate Layer asphalt concrete mixture (AC-BC) of the two compositions. Almost all Marshall properties meet the Directorate General of Highways specifications in 2018 Revision 3, except for Flow with a particle size of 19 mm, which does not meet the specified flow range of 2 – 4 mm, and Marshall Stability for Aggregate Residue with a particle size of 19 mm, which does not meet the specified minimum of 90%. Meanwhile, the Optimum Asphalt Content (OAC) values for Aggregate with a particle size of 25 mm are 5.11%, and for Aggregate with a particle size of 19 mm, it is 5.18%.

Abstract

Compaction is a crucial factor that affects the quality and performance of road pavements. This study evaluates the impact of varying compaction blows at the optimum asphalt content on Lataston (HRS-Base) mixtures using the Marshall Test method. The tested compaction variations are 2 x 40, 2 x 50, 2 x 60, and 2 x 70 blows. The results show that stability values increase from 841.19 kg at 2 x 40 blows to 1151.42 kg at 2 x 70 blows. Flow values decrease from 3.45 mm at 2 x 40 blows to 3.18 mm at 2 x 70 blows. The Marshall Quotient (MQ) increases from 243.85 kg/mm at 2 x 40 blows to 362.72 kg/mm at 2 x 70 blows. The Void in the Mineral Aggregate (VMA) decreases from 19.30% at 2 x 40 blows to 17.02% at 2 x 70 blows. The Void in Mix (VIM) also decreases from 5.22% at 2 x 40 blows to 2.54% at 2 x 70 blows. The Void Filled with Asphalt (VFA) increases from 72.94% at 2 x 40 blows to 85.10% at 2 x 70 blows. The density of the mixture increases from 2.271 gr/cm³ at 2 x 40 blows to 2.335 gr/cm³ at 2 x 70 blows. However, only the 2 x 50 blows variation meets all the parameters specified in Bina Marga 2018 Revision 2. The 2 x 40 blows compaction results in low MQ and high VIM, while the 2 x 60 and 2 x 70 blows compaction results in VIM below the minimum limit. These findings highlight the importance of balanced compaction to enhance road pavement quality.

Abstract

According to SNI 1726-2019, hospitals are in category IV building risk which has high factor importance for building planning against earthquakes. Therefore, an evaluation of buildings is needed which is not only affected by earthquakes but also the strength, stiffness, and ductility of the building itself. This study aims to produce the performance of the Guido Valadares National Pediatric Hospital and ICCU Building using pushover analysis. The results of the analysis show that there is a deviation failure caused by the presence of a ramp on one side of the building which results in greater stiffness on that side than on the other side of the building. A new structural system is applied on the lower side of the building with bracing reinforcement to create balance for the building. The new design results reveal better building structure performance and it is in accordance with applicable standards.

Abstract

Asphalt concrete has become the primary choice for road construction in Indonesia due to its elastic properties suitable for tropical regions. Hot Rolled Sheet-Wearing Course (HRS-WC), as one type of flexible pavement, plays a crucial role in supporting traffic from light to heavy loads. The objective of this study is to compare the Marshall characteristics of HRS-WC mixtures using materials from Inbate river and Bijaesahan river in the East Nusa Tenggara Province. The research method involved testing the material characteristics, mixing HRS-WC, and conducting Marshall method testing. The results indicate that the material from Inbate river exhibits better performance in stability and flexibility compared to material from Bijaesahan river. At the optimum asphalt content of 6.93%, the stability of Inbate river material was 1199.31 Kg, whereas Bijaesahan river was 957.68 Kg. Additionally, the flow of Inbate river material was 4.67 mm, while Bijaesahan river was 3.40 mm. Similar results were observed at the optimum asphalt content of 7.28%, with Inbate river showing stability of 1179.59 Kg and Bijaesahan river 944.16 Kg. The flow of Inbate river material was 4.84 mm, whereas Bijaesahan river was 3.48 mm. These findings demonstrate that material from Inbate river outperforms in stability and flexibility.
