Abstract

Penelitian ini menganalisis dan memprediksi persentase anak muda usia 15-24 tahun di Indonesia yang tidak bersekolah, bekerja, atau mengikuti pelatihan (NEET) menggunakan model regresi linear berdasarkan data dari tahun 2015 hingga 2023. Latar belakang penelitian menekankan pentingnya menangani peningkatan angka NEET karena implikasi sosial ekonomi jangka panjangnya. Data dikumpulkan dari sumber resmi dan dianalisis menggunakan Google Colab. Hasilnya menunjukkan adanya tren peningkatan kecil namun konsisten dalam persentase NEET dari tahun ke tahun, dengan prediksi akan mencapai 23,34% pada tahun 2030. Tren ini menegaskan perlunya intervensi yang lebih efektif dalam pendidikan dan pasar tenaga kerja untuk mengurangi angka NEET. Penelitian ini menyimpulkan bahwa meskipun telah ada upaya untuk mengatasi masalah ini, tantangan signifikan masih ada, sehingga dibutuhkan kebijakan yang lebih kuat dan program pelatihan yang lebih tepat sasaran. Validasi lebih lanjut dan penggunaan model analisis yang lebih kompleks direkomendasikan untuk meningkatkan akurasi prediksi di masa depan.

Abstract

Danez Health Care is a pharmaceutical service facility that has been established since 2014 and now has 1 Clinic branch and 4 Pharmacy branches in Purwakarta, Bekasi and Bogor. Danez Health Care's head office is in the same location as its clinic, namely in Bogor. However, the attendance process that occurs at Danez Health Care is still done manually by each branch which makes it difficult for Finance / HRD to control working hours and calculate the net salary of employees at each branch. Seeing the existing problems and to make it easier for Finance/HRD to control employee working hours and attendance accuracy, a website-based employee attendance and payroll application is needed using the Laravel framework and scrum methodology. To produce salary calculations that are directly systemised on employee attendance data, it also makes it easier to collect attendance data. The design of the application uses UML design tools, balsamiq mockup, xampp and mysql as a database. The results of this study are in the form of an attendance application that can be directly connected to the calculation of employee net salaries every month, and can produce pay slips, employee absence recap data from all branches, calculation of employee net salaries that can provide information quickly to Finance/HRD.

Abstract

**Abstrak** Perkembangan Internet yang pesat telah mempengaruhi berbagai bidang, dari pendidikan hingga bisnis, dengan lebih dari 5 miliar pengguna di seluruh dunia. Evolusi teknologi web, dari Web 1.0 hingga Web 3.0, menunjukkan perubahan signifikan dalam cara informasi disajikan dan bagaimana pengguna berinteraksi dengan data. Web 1.0 hanya memungkinkan akses satu arah terhadap informasi, sedangkan Web 2.0 memungkinkan interaksi dinamis antara pengguna dan konten melalui media sosial dan blog. Saat ini, Web 3.0 membawa konsep desentralisasi dengan memanfaatkan teknologi blockchain yang memungkinkan pengguna memiliki kendali penuh atas data mereka. Penelitian ini bertujuan untuk mengembangkan dan menguji aplikasi berbasis Web 3.0 yang menggunakan teknologi blockchain untuk penyimpanan dan pengelolaan data secara aman, efisien, dan terdesentralisasi. Meski prototipe yang dikembangkan dalam penelitian ini masih menggunakan penyimpanan data terpusat, konsep desentralisasi yang sesungguhnya akan diterapkan pada pengembangan lanjutan. Penyimpanan data dalam blockchain menawarkan keuntungan berupa keamanan dan transparansi yang lebih tinggi, meskipun dengan biaya yang lebih besar. Aplikasi ini diharapkan mampu mengatasi kebutuhan mendesak akan penyimpanan data yang aman dan terdesentralisasi, terutama untuk data yang membutuhkan tingkat kepercayaan dan integritas tinggi, seperti catatan medis, data keuangan, dan persediaan barang di gudang.

Abstract

Expand Tube is a deformation process that is carried out in a cold state, to obtain a density between the tube and the tube hole in the tube sheet. This process aims to obtain a tight/tight connection so as to prevent leaks and not be separated from the seat, while minimizing stress corrosion and cracks axially in the transition zone behind the tube sheet. heater H072: 1. Carry out the stages of expanding tube heat exchanger ethylene super heater H072. 2. Obtain data on the tube when the process of expanding the tube heat exchanger ethylene super heater H072 is carried out. 3. Know the acceptance criteria for the process of expanding tube heat exchanger ethylene super heater H072. Writing conducted research with several methods including: 1. Observation method at PT. Diamond Prima Kalorindo. 2. Interview Method. 3. Literature Study Method. PT Intan Prima Kalorindo imports materials from Korea, but these materials are controlled by PT Intan Prima Kalorindo so that these materials are in accordance with consumer demand, during the expansion process it requires 2 materials, namely Aluminum Silicon 304 Stainless Steel. The Expand process is a deformation process that is carried out in a cold state, to obtain a density between the tube and the tube hole in the tube sheet. Where the tube has reached 'plastic' while the tube sheet is still in the 'elastic' stage. This process aims to obtain a tight/tight connection so as to prevent leakage and not detach from the seat, while minimizing stress corrosion and axial cracking in the transition zone behind the tube sheet. All expand calculations refer to TEMA 10th standards (Tubular Exchanger Manufactures Associations, Inc) and API 660 (American Petroleum Institute).

Abstract

This research build to predict one of the natural disasters in Indonesia, that is Active Volcano which could erupt at any time. This natural disaster occurs quite often in Indonesia and results in losses for residents who live around active volcanoes. Based on this, the researcher wants to create a decision tree that can help predict the situation before a volcano erupts, which can later be applied so that residents around active volcanoes and ordinary people can know the signs before a volcanic eruption occurs. This research will use the application of data mining with the c4.5 algorithm method as a tool in creating decision trees.

Abstract

Nutrient Agar (NA) is a growth medium for heterotrophic microorganisms made from meat extract, peptone and agar, but commercially it is relatively expensive. As an alternative, researchers innovated using white sweet potatoes (Ipomoea batatas) which are rich in carbohydrates, protein, fat and natural fiber as a growth medium for Escherichia coli bacteria. The aim of this research is to examine the use of white sweet potato flour as a growth medium for Escherichia coli bacteria, and compare it with a medium that is added with meat broth. This research used the experimental research method twice with three repetitions of sweet potato flour, namely 10gr (w/v), 15gr (w/v), 20gr (w/v) and NA control. After conducting research on white sweet potato flour, it was found that the water content test results met the standards of around 8.56–9.66%. The panelists' organoleptic test stated that white sweet potato flour had a smooth texture, yellowish white color, slightly sweet aroma. The solubility test proved that white sweet potato flour does not dissolve in water, and the pH test showed a value of 6.8, the percentage of carbohydrates contained was 74.32%, and protein 1.36%. The results obtained by the number of bacterial colonies with the best treatment without broth were F3 (20 gr white sweet potato flour) 25.5 x 106 CFU and the best treatment with the addition of broth was F2 (sweet potato flour + 15 gr broth) 28.7 x 106 while the NA control showed results of 25.6 x 106 CFU. It can be concluded that white sweet potato flour meets all test standards so that it can be used as an alternative growth medium for bacteria, especially Escherichia coli.

Abstract

PT Panasonic Manufacturing Indonesia is one of the largest manufacturing companies producing electronic products in Indonesia, achieving significant growth and development in its production processes. Ensuring an efficient production process requires maintaining proper line balancing to achieve smooth operations. However, the radio P155 Srs production line experienced workload imbalances that led to bottlenecks and time losses. These issues arose due to factors such as insufficiently skilled workers and mismatched workloads that were not aligned with operators' abilities. Such conditions can lead to worker fatigue and reduced motivation and negatively impact work effectiveness. Research conducted using the Ranked Position Weight (RPW) method demonstrated improvements by reducing the number of workstations from 12 to 8. This optimization resulted in increased track efficiency, which improved from 65.10% and 57.43% to 83.10% and 85.94%.

Abstract

The problem of poverty is a complex and multidimensional problem so it is a development priority for the Indonesian Government. Efforts to eradicate poverty are carried out to realize the nation's ideals, namely, the creation of a just and prosperous society. The Urban Poverty Alleviation Program (P2KP) is a national program implemented by the Indonesian Government in order to overcome the problem of poverty that occurs in society, especially people living in urban areas. The level of poverty in the city of Depok which is explained in written form is less effective and difficult for readers to understand. Therefore, this data visualization dashboard was created by the author to help readers understand the state of poverty levels in the city of Depok through several existing factors. The dashboard consists of several visuals to differentiate poverty factors. Based on tests that have been carried out using UAT (User Acceptance Testing) to determine the reader's assessment of the data visualization dashboard that has been created by distributing questionnaires to 50 respondents, resulting in a score of 82.5% which results in a "very strong" category for the Percentage Level data visualization dashboard.
