PENGGUNAAN REINFORCED CONCRETE SLABS UNTUK MENGURANGI PENURUNAN SESAAT PONDASI TIANG PANCANG PADA TANAH TIDAK KERAS

2024-08-06T12:16:32+07:00

Kejadian penurunan sesaat pada pilar-pilar struktur jembatan tipe pelat tiang, pada saat kendaraan melintasi jembatan, merupakan pengaruh dari pondasi pegas. Efek ini umumnya terjadi karena pondasi tidak berada pada tanah yang keras. Penurunan sesaat tersebut menyebabkan pelebaran momen di ujung dermaga sehingga mengakibatkan peristiwa retak struktur, seperti yang terjadi pada salah satu ruas tol di Kebon Jeruk, Jakarta Barat. Pilar struktur jembatan type pile slab yang pondasinya berada pada tanah yang tidak keras akan mengakibatkan pilar tersebut mengalami pergerakan vertikal. Pergerakan pada pilar dapat menyebabkan keretakan pada struktur pier head, selanjutnya pergerakan pada pier head juga dapat menyebabakan kerusakan pada lantai. Dalam penelitian ini dilakukan evaluasi terhadap perkuatan dengan tujuan mengetahui kinerja perkuatan pada pondasi. Salah satu cara untuk mengatasi penurunan sesaat pada pondasi yang berfungsi sebagai pilar adalah dengan mengurangi penurunan sementara dengan cara mendistribusikan beban pada tanah di sekitar pondasi dengan menggunakan pelat beton bertulang. Hasil analisis teoritis, penanganan menggunakan pelat bertulang dengan luas 2,5 x 2,5 meter, dengan pemasangan sedalam 0,5 meter dari permukaan tanah, mampu meredam pergerakan vertikal sebesar 73,68% (penurunan sebelum perkuatan sebesar 0,76 mm, dan setelah perkuatan sebesar 0,20 mm). Sedangkan dari hasil uji lapangan dengan penanganan seperti diatas mampu menurunkan penurunan sesaat sebesar 68,75%. (penurunan sebelum perkuatan sebesar 0,80 mm, dan setelah perkuatan sebesar 0,25 mm)

Design of an Automatic Clothes Drying System Based on Internet of Things (IoT) Technology

2024-08-06T12:00:18+07:00

Drying clothes is an activity that is generally carried out outdoors using sunlight to speed up the drying of clothes. Some people who do a lot of activities outside the home often leave their clothes hanging all day. Along with the erratic changes in seasons, sudden rain can cause clothes that have been dried in the sun to become wet again due to exposure to rainwater. To overcome this problem, automatic clothes drying system based on Internet of Things (IoT) technology was created using LDR sensors and rain sensors. This system uses the Blynk application so that it can be monitored and controlled directly. Wemos D1 R32 is used as a communication medium between the device and the Blynk application. The results of this research are that the clothesline can enter the room when the LDR sensor detects that it is dark or when it is raining and when the user orders the clothesline to enter via the Blynk application

A digital document tracker on a file storage system uses a combination of the SHA3-512 and RSA algorithms to safeguard the authenticity of document data

2024-08-06T12:07:54+07:00

The aim of this research is to analyze the security
of digital signature schemes, so that the integrity of
the data in the signature document is better
maintained and the recipient is trusted to have come
from a legitimate sender. The rapid development of
technology today means that all signed physical
documents have turned into softfile documents with
digital signatures. The process of creating a digital
signature begins with creating a public key and a
private key. A public key is generated and published
to verify the signature and calculate the hash value of
the received document. Several studies have used the
concept of algorithms in cryptography, namely the
RSA cryptographic algorithm, but it still has
shortcomings in that it cannot be proven whether the
document received by the recipient is a document
from a legitimate sender and there have been no
changes to the document. In this research the author
tries to perfect previous research where users can
validate the authenticity of documents and believe
that the sender of the document is a legitimate sender
with a combination of the RSA and SHA3-512
algorithms. The document used in this research has
.pdf extension. Mitm attack testing resulted in the
conclusion that the strength of the secret key was the
basis for the scheme being built. The digital signature
scheme that is built can validate the authenticity of
documents received by the recipient and prove that
the document was sent by a legitimate sender. Time
for document validation and signature depends on the
size of the uploaded pdf file

UI/UX DESIGN OF GENERAL MEDICAL CHECK-UP FOR X MINING COMPANY USING SURVEY AND INTERVIEW METHODS

2024-08-06T12:13:45+07:00

The mining industry, a crucial component of the world economy, is inextricably
linked to occupational safety hazards and serious health dangers. Effective work safety
measures are critical in sustaining worker health, one of which is routine Medical CheckUp (MCU). Mining Company X's MCU installation has been completed, but operating
conditions and reporting remain manual, and inspection procedures and job eligibility
assessments are inconsistently implemented. As a result, it is vital to digitize the MCU
process using the General Medical Check-Up (GeMCU) system. This final project
implements the survey and interview method, with testing conducted utilizing System
Usability Scale (SUS) and User Acceptance Test (UAT), to assess user usability and
satisfaction. The test findings showed that the average score of the System Usability Scale
(SUS) test was 75.25 with the "Good" category, and the average score of the User
Acceptance Test (UAT) test in each element was 90% for the design aspect, 84% for the
user-friendliness aspect, and 82% for the efficiency aspect. Thus, the results of this test can
be used as a basis for the feasibility of GeMCU UI/UX design by mining company X.

Fuzzy Inference System For Recommendation Of Student's Depression Level

2024-08-08T20:21:50+07:00

Depression is common in modern society and can cause various kinds of problems, for example behavioral, social and psychological problems. Sanggar Kegiatan Belajar 26 Bintaro is a non-formal educational institution that does not yet have counseling teachers like other formal schools, so tools are needed to carry out early detection of students' depression levels in the form of a depression level recommendation system whether at normal, mild, moderate or severe levels which is useful for Teacher to provide the right solution. The method used in this research is fuzzy logic with seven (7) input variables sourced from the Depression Anxiety Stress Scale-21 (DASS-21) questionnaire and four output variables, namely normal mild level depression, moderate level depression and severe level depression. The programming language used is Python using the Simpful library. The results of the research are measurements using DASS-21 for depression. The recommendation results are the same as using the fuzzy logic method, so that fuzzy logic can be used to make recommendations for early detection of students' depression levels.
