Implementation Of Construction Management System Based On Information Technology (IT) And Integrated Towards Digital Construction in Industry 4.0
Full text linkThe world of construction from time to time does not stand still, but continues to develop in various ways.
Developments in the construction world aim to make it easier for the parties involved in completing their respective
responsibilities. As time goes by and demands to speed up the process of completing work, nowadays we find more and
more software and applications that are used to support construction work. The use of this software will make the work
products of construction actors more efficient, effective and productive where this is the goal of all construction actors.
Several construction companies that develop information technology infrastructure in the form of software are PT Tunas
Jaya Sanur, PT Mardika Griya Prasta and PT Sanur Jaya Utama with their Integrated Project Management System
(IPMS) software. This study aims to compare the company's performance after and before using information technology
(IT) infrastructure and to find out the advantages and disadvantages of using information technology infrastructure,
especially at PT Tunas Jaya Sanur, PT Mardika Griya Prasta and PT Sanur Jaya Utama. Comparison of the performance
of PT Tunas Jaya Sanur, PT Mardika Griya Prasta and PT Sanur Jaya Utama after using information technology
infrastructure, the whole process can be faster in terms of time, and in terms of costs, this system can reduce operational
costs and staff costs so that the company can become more efficient. efficient, effective and productive. The advantage of
using this information technology infrastructure is that it is faster in terms of time, more efficient in terms of operational
costs, more environmentally friendly because it uses less paper and can be done anywhere. While the drawback is that it
requires investment costs at the beginning and must be connected to the internet
Simvastatin: a new therapeutic strategy for Chronic Kidney Disease (CKD)
Full text linkBackground: Chronic kidney disease (CKD) is a progressive disease whose prevalence increases annually. Studies in recent
years report that statins (hydroxy-3-nethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors) affect preventing the
progression of kidney damage, in addition to their ability to prevent cardiovascular risk in patients with CKD. This study aims
to determine the effect of statins on kidney function and renal fibrosis in chronic kidney disease.
Methods: This research is pure experimental (randomized post-test only control group design). The research sample
consisted of 20 white mice (Mus musculus L.), Swiss line, aged 3-4 months, and weight 30-40 grams. Samples were randomly
grouped into four treatment groups: control (K, n = 5), treatment with simvastatin at a dose of 5.2 mg/kgBW (P1), treatment
with simvastatin at a dose of 10.4 mg/kgBW (P2), and treatment with simvastatin at a dose of 20.8 mg/kgBW (P3). Interstitial
f
ibrosis was assessed using Picrosirus Red staining. Data analysis used One-Way ANOVA and Tukey’s post hoc tests with a
significance value of p<0.05 in SPSS version 25.0 for Windows.
Results: The results showed that the control group (K) was the group with the highest serum creatinine level (1.07 ± 0.43)
compared to the other treatment groups (p <0.05). Administration of simvastatin at doses of 5.2 mg/kgBW, 10.4 mg/kgBW,
and 20.8 mg/kg BW in CKD mice resulted in lower interstitial fibrosis than controls. There was a significant difference between
renal tissue fibrosis in the simvastatin group at a dose of 5.2 mg/kgBW (P1) with a dose of 10.4 mg/kgBW (P2) and a dose of
20.8 mg/kgBW (P3).
Conclusion: Simvastatin can improve kidney function and reduce the degree of renal fibrosis in animal models of CKD. Thus,
it can be a therapeutic strategy for CKD

Analysis Comparison of Moment Resisting Frame System and Concentrically Braced Frame System using Inverted – V Brace
Full text linkIndonesia is a country located in the path of the Pacific earthquake and the Asian earthquake path that results in
a very high risk of earthquakes. Vibrations caused by earthquakes will cause forces on the structure. The design of
earthquake-resistant buildings is one of the objectives to prevent structural failure and loss of life. Adding rigidity to a
building is a way to overcome resistance to earthquake response. Acquiring stiffness in the structure can be done by
combining it with bracing. One type of bracing frame system that can be used is the Concentrically Braced Frame (CBF)
system. The analytical method that can be used in this study to account for the effect of earthquake load on the structure is
done to analyze the structure's response to lateral load with static analysis and dinamic analysis with comparative analysis
of displacement, vibrating period, shear force, and shear lag in buildings. Based on the results of the analysis, the CBF
system can reduce the effect of shear lag on the structure. The rigidity of the CBF System is higher than that of the MRF
system so that the floor drift and deviation between floors in the system become smaller. The deviation for the x-direction
CBF system produces a smaller value of 5% - 32.2%, and for the y-direction it produces 7.2% - 41.7%. In the natural
vibrating period of the MRF System structure of 1.311 seconds, this period is worth greater than the period in the CBF
System of 0.453 seconds
Analysis of Selection Criteria of Bridge/Shortcut Construction on National Road Denpasar – Gilimanuk
Full text linkBali has variable contours (from ramps to steep) so that roads in Bali have a level of difficulty in vertical
or horizontal alignment, also a heritage road that does not match the demands of current traffic such as the number of
vehicles that are getting bigger, the size of the vehicle is getting bigger and the weight of the vehicle is getting
heavier. In the area reviewed is a national road that is quite dense and has been done improvements in the form of
bridges and shortcut roads on the Denpasar – Gilimanuk road including Samsam shortcut and Megati shortcut.
Preliminary Survey with geometric data processing methods with maps, there are 53 curve points. Furthermore, the
government urgently needs to process data from these 53 points into a priority point of handling given the very
limited funds. The purpose of this study is to find a priority scale for the construction of bridges/shortcuts. Due to
limited costs, other methods are needed, such as accident-prone points and traffic jams, as well as checking vertical
alignments. The results of the survey and analysis obtained 7 points that are a priority for improvement because in
terms of vertical, horizontal, and from points prone to accidents or congestion. It is recommended to be handled with
the repair of alignment and the construction of bridges or shortcuts. It is recommended to be handled with the repair
of alignment and the construction of bridges or shortcuts
NILAI RESISTIVITAS DAN STRUKTUR BATUAN VULKANIK PASCA GEMPA DI KALDERA GUNUNG BATUR SERTA USAHA MITIGASI
Full text linkGempa tektonik tanggal 16 Oktober 2021 menyebabkan terjadinya longsor dengan dua korban jiwa dan kerusakan rumah warga, terputusnya akses jalan, tepatnya di Dusun Cemara Landung. Debris flow dan Rock fall terjadi berlanjut pada ruas jalan menuju Dusun Terunyan. Penelitian untuk mengetahui pemicu longsoran dilakukan dengan uji geolistrik dan foto udara dengan drone. Pengamatan profil tanah dilakukan alat geolistrik metode Wenner. Analisis dan kajian ini menghasilkan korelasi antara pemetaan morfologi longsor dan kondisi lapisan tanah dan batuan, sebagai acuan pemicu longsor akibat gempa dan usaha mitigasi selanjutnya bagi masyarakat sekitar kaldera Gunung Batur. Kajian menunjukkan penumpukan material tanah endapan jenuh pada patahan lereng dan lembah dangkal, adanya sesar pada lereng pengamatan dan foto udara. Pengamatan dengan Geolistrik menunjukkan nilai resitivitas didominasi nilai resitivitas berkisar 516 - 252 Ωm, dipermukaan nilai resitivitas tinggi berupa batuan lepas nilai resistivitas 788 - 2168 Ωm, dan terdapat patahan lereng dengan endapan pasir dan lanau dengan nilai resistivitas rendah 29,2 – 111 Ωm. Kajian pemicu longsor akibat gempa karena adanya patahan serta lembah dangkal dengan material jenuh air, serta endapan tipis sekitar 1,5- 2 m diatas bed rock. Lapisan tanah berupa pasir, batu pasir, dan andesit dengan kepadatan yang berbeda-beda cenderung lepas. Sebagai daerah tujuan wisata untuk menjaga keamanan dan kenyamanan turis perlu usaha mitigasi bencana tanah longsapsor dengan non struktural melalui edukasi kepada masyarakat dan pelaku pariwisata. Mitigasi struktural tetap mengedepankan sisi estetika dan alami seperti membangun konstruksi cekdam, dinding penahan tanah alami dan konstruksi rock fence dari jaring bambu
