Analisis Sentimen Terhadap Ulasan Hotel Melalui Platform Google Review Menggunakan Metode Stacking
Get PDFIn the digital era, the internet has become the main source of information for the public, including when searching for hotel information. One platform frequently used for finding hotel information is Google Review, which allows hotel guests to share their experiences. This study aims to analyze sentiments towards hotel reviews, specifically for hotels in Jakarta, through Google Review to help customers choose hotels that meet their needs. The research method uses Serp API in Python to gather review data from Google Review, followed by data preprocessing and labeling with VADER. Sentiment classification is conducted using a stacking ensemble method. The stacking ensemble method in this study employs Naive Bayes, Random Forest, Logistic Regression, Support Vector Machine, K-Nearest Neighbor, and Extra Trees Classifier as base algorithms. The sentiment classification results are then evaluated using precision, F1-score and accuracy metrics. The research findings show that the stacking ensemble method with Naive Bayes, Random Forest, Logistic Regression, Support Vector Machine, K-Nearest Neighbor, and Extra Trees Classifier algorithms performs better than individual models. The precision, F1-Score and accuracy of the stacking ensemble method reach 91%, 97%, 98%, respectively.Di era digital ini, internet menjadi sumber informasi utama bagi masyarakat, termasuk dalam mencari informasi tentang hotel.

Rancang Bangun Alat Otomatisasi Pengomposan dari Sampah Organik Berbasis Internet of Things
Get PDFOrganic waste management in Indonesia is currently suboptimal. Approximately 33.7% of waste is not properly managed, and 56% of the total waste consists of organic waste, most of which comes from households. Composting is an effective method for managing organic waste. However, many people are still reluctant to convert organic waste into compost due to the lengthy process, which typically takes 2 to 3 months. This study proposes an IoT-based composting automation system with the goal of accelerating the composting process without the use of additional microorganisms, producing both dry and liquid compost. The system method involves integrating Internet of Things (IoT) technology with sensors: DHT22 for temperature monitoring, soil moisture sensors for measuring soil moisture, MQ-4 sensors for detecting methane gas, pH sensors for measuring soil acidity, and water level sensors for detecting the height of liquid compost. Data collected from these sensors is used to automatically control the organic waste mixing process until all composting specifications are met. The results indicate that this system effectively accelerates the composting process to 24 days for dry compost and 19 days for liquid compost without the need for additional microorganisms, while producing compost of high quality according to the SNI-19-7030-2004 specifications
Prototipe Powered Emergency Resuscitator Berbasis Bag Valve Mask
Get PDFThe COVID-19 pandemic proves that healthcare capacity and equipment are not sufficient to handle a pandemic, especially the availability of ventilators. Composed of more than 17.500 islands, 6.000 of which are inhabited, Indonesia’s demographic varies widely from one area to another. Health infrastructure in many areas is minimal, with many having no hospitals but clinics with limited resources/funds and minimally-trained healthcare professionals. The need for domestically produced ventilators is clear. But not only that, there is a need to produce simpler/more economical ventilators that are affordable and simpler to operate. This paper will discuss the basic ventilator (resuscitator), built upon MIT Open Design (used by clinics/smaller hospitals) and was in the last development phase before product testing at Balai Pengamanan Fasilitas Kesehatan (BPFK) Jakarta.Pandemi COVID-19 membuktikan bahwa kapasitas dan peralatan kesehatan tidak cukup untuk menangani pandemi, terutama ketersediaan ventilator. Terdiri dari lebih dari 17.500 pulau, 6.000 di antaranya berpenghuni, demografi Indonesia sangat bervariasi dari satu daerah ke daerah lain. Infrastruktur kesehatan di banyak daerah sangat minim, dengan banyak yang tidak memiliki rumah sakit hanya klinik dengan sumber daya/dana yang terbatas dan profesional perawatan kesehatan yang minim pelatihan. Kebutuhan ventilator produksi dalam negeri sudah jelas. Namun tidak hanya itu, ada kebutuhan untuk memproduksi ventilator yang lebih sederhana/ekonomis yang terjangkau dan lebih mudah dioperasikan. Makalah ini akan membahas ventilator dasar (resusitator) yang dikembangkan berdasarkan Desain Terbuka MIT (untuk digunakan oleh klinik/rumah sakit kecil). Prototipe yang dikembangkan telah berada dalam tahap pengembangan terakhir resusitator darurat otomatis (powered emergency resuscitator) sebelum uji produk di Balai Pengamanan Fasilitas Kesehatan (BPFK) Jakarta
PELANGGARAN HAK CIPTA TERHADAP INDUSTRI KREATIF DAN LANGKAH HUKUM YANG DAPAT DITEMPUH
Get PDFCopyright infringement is an increasingly pressing issue in the digital era, especially for creative industries that rely on innovation and originality as their backbone. The impact of copyright infringement on the creative industry is very detrimental, both from an economic and moral perspective. Economically, copyright infringement can reduce the income of creators, discourage investment in new work, and damage a healthy creative ecosystem. Morally, these violations erode the spirit of innovation, affect the reputation of creators, and create injustice for those who have invested time and resources in creating original works. To deal with this issue, various legal steps can be taken, including strengthening copyright regulations, increasing legal awareness among the public, and implementing strict sanctions for violators. The use of advanced technologies, such as digital rights management (DRM) systems and automated content monitoring, can also assist in detecting and preventing copyright infringement. In addition, collaboration between government, law enforcement and creative industries is very important to create a conducive environment for copyright protection. With these steps, it is hoped that copyright infringement can be minimized, so that the creative industry can develop more fairly and sustainably, and provide maximum contribution to the economy and culture.

Merubah Pola Pikir Saving Society Menjadi Investing Society Pada Siswa Siswi Sma Negeri I Dan Sman 2 Batang Anai Padang Pariaman
Get PDFTidak dapat dipungkiri bahwa Pasar Modal memiliki peran penting bagi perekonomian satu negara karena pasar modal menjalankan dua fungsi, pertama sebagai sarana bagi perusahaan untuk mendapatkan dana dari masyarakat pemodal (investor). Dana yang diperoleh dari pasar modal dapat digunakan untuk pengembangan usaha,ekspansi,penambahan modalkerja dan lain-lain, kedua pasar modal menjadi sarana bagi masyarakat untuk berinvestasi pada instrument pasar seperti saham, obligasi, reksadana,dan lain-lain. Dengan demikian, masyarakat dapat menempatkan dana yang dimilikinya sesuai dengan karakteristik keuntungan dan risiko masing-masing instrumen. Tingkat pemahaman (literasi) masyarakat Indonesia terhadap pasar modal dan tingkat utilitas produk pasar modal masih sangat rendah dan yang terkecil dibandingkan dengan lima industri jasa keuangan lainnya (keuangan, asuransi, perbankan, pegadaian, pensiun) di Indonesia. Oleh karena itulah Lembaga Penelitian Pengabdian Masyarakat (LPPM) UNIDHA) memberikan edukasi awal kepada siswa-siswi dengan tujuan turut merubah pola pikir saving society menjadi investing society. Metode yang dilakukan dengan memberikan pengenalan teori dasar Pasar Modal oleh Tim dosen dan Pengurus GISBEI UNIDHA dan praktik stocklab games oleh mahasiswa Pengurus GISBEI UNIDHA. Dari pengenalan pasar modal kepada siswa siswi MAN 2 Padang sejak dini dan dikenalkan nabung saham, agar kedepan generasi milenial Indonesia bisa menuju investing society
