Singkong menjadi salah satu tanaman penting pada bidang agronomi dan banyak dikonsumsi oleh masyarakat. Namun, terdapat salah satu kendala dalam menjaga kelestarian tanaman singkong yaitu pendeteksian penyakit. Jika penyakit pada tanaman singkong dapat terdeteksi lebih dahulu melalui citra daunnya, maka penyakit tersebut dapat segera diobati. Proses klasifikasi dapat dilakukan untuk mendeteksi penyakit pada tanaman secara otomatis. Pada penelitian ini dilakukan klasifikasi tanaman singkong dengan menggunakan beberapa tahap pra-proses yaitu pra-proses dengan augmentasi, tanpa augmentasi dan pra-proses dengan rotasi, pada beberapa metode transfer learning seperti ResNet50 dan MobileNetV2. Penggunaan beberapa metode tersebut bertujuan untuk mencari metode mana yang memiliki hasil akurasi tertinggi. Penelitian menunjukkan bahwa MobileNetV2 tanpa augmentasi memberikan akurasi tertinggi sebesar 98.64% dalam mendeteksi penyakit tanaman singkong. Hal ini dapat menjadi referensi bagi peneliti selanjutnya dalam menentukan tahap pra-proses terbaik dalam metode transfer learning.
Background: Covid-19 is a new disease for which no cure has been found; prevention of disease transmission is an alternative to reducing cases. The workplace is one of the places that have the potential for information of Covid-19 because workers will have direct contact in one place with other workers. This study aims to analyze the characteristics and availability of health protocol facilities on worker compliance in the workplace during the Covid-19 pandemic. Methods: The research method uses quantitative methods with a cross-sectional approach. The population in this study are workers who work in formal and informal sectors in Indonesia, with a sample of 217 respondents. Data collection used a survey method and obtained as much as 217 data. For data processing, we used the Rank Spearman test. Results: The results showed that there was a relationship between years of service (p-value 0.008; rho: 0.148), educational level (p-value 0.000; rho: 0.363), number of employees (p-value 0.000; rho: 0.488), and the availability of health protocol facilities (p-value 0.000; r: 0.498) at the workplace. As for age and the level of compliance with the application of health protocols, there was no relationship (p-value 0.044). Discussion: The level of compliance with suitable health protocols at the workplace can help suppress the spread of Covid-19. There are still workplaces where workers do not comply with health protocols, such as workers who do not practice social distancing and lower masks to their chins when talking to colleagues.
<p>Estimasi biaya sampai sekarang masih menjadi salah satu permasalahan utama dalam perencanaan proyek perangkat lunak. Estimasi biaya ini memiliki peran yang penting karena berpengaruh pada berjalannya proyek dan menjadi penentu keberhasilan suatu proyek perangkat lunak. Kegagalan estimasi biaya dalam perencanaan proyek perangkat lunak dapat menyebabkan proyek tidak berjalan dengan baik dan menimbulkan kerugian bagi perusahaan. Oleh karena itu, banyak peneliti sampai saat ini masih mencari dan melakukan penelitian untuk mendapatkan estimasi terbaik. Berbagai metode diusulkan untuk mendapatkan ketepatan akurasi dengan memperhatikan faktor-faktor estimasi biaya. Tujuan penelitian ini adalah membuat <em>Systematic Literature Review</em> (SLR) yang berisi rangkuman dan analisis perkembangan penelitian terbaru tentang estimasi biaya pada perangkat lunak, khususnya pada metode yang digunakan serta faktor-faktor yang mempengaruhi. Penelitian ini berhasil mengkaji 21 penelitian lain dalam lima tahun terakhir (2015-2020) dan didapatkan 24 metode usulan yang terbagi menjadi tiga jenis metode yang sering digunakan dalam melakukan estimasi biaya perangkat lunak yaitu nonparametrik, parametrik dan semiparametrik. Selain itu, penelitian ini juga berhasil menemukan metode dan kombinasi metode terbaik berdasarkan ketepatan akurasi beserta lima faktor utama yang mempengaruhi estimasi biaya sehingga dapat digunakan para peneliti atau praktisi lain untuk mengembangkan estimasi biaya pada proyek perangkat lunak.</p><p> </p><p><em><strong>Abstract</strong></em></p><p class="Abstract"><em>Cost estimation has an important role because it affects the project’s progress and determines the success of a software project. Failure to estimate costs in software project planning can cause the project to not run well and cause losses to the company. Therefore, many researchers are still looking for and researching to get the best estimation by considering the cost estimation factors. The purpose of this study is to create a Systematic Literature Review (SLR) which contains a summary and analysis of the latest research developments on cost estimation in software, especially in the methods used and the factors that affect cost estimation. This study successfully reviewed 21 other studies in the last five years (2015-2020) and obtained 24 planning methods which are divided into three types of methods that are often used in conducting software cost research, namely nonparametric, parametric and semiparametric. Besides, this study also succeeded in finding the best method and combination of methods based on best accuracy, namely COCOMO II and the combination of Genetic Algorithm and Artificial Bee Colony, along with the five main factors that influence cost estimation so that it can be used by researchers or other practitioners to develop cost estimates for software projects.</em></p><p><em><strong><br /></strong></em></p>
Hadith is the second source of reference for Islamic law after the Qur'an, which explains the sentences in the Qur'an which are still global by referring to the provisions of the Prophet Muhammad SAW. Classification of text documents can also be used to overcome the problem of interrelation between the Qur'an and hadith. The problem of interrelation between books of hadith needs to be done because some hadiths in certain hadith books have the same meaning as other hadith books. This study aims to analyze the development of text representation and classification methods suitable to overcome similarity meaning problems in detecting interrelationships between hadith books. The research method used is Systematic Literature Review (SLR) sourced from Google Scholar, Science Direct, and IEEE. There are 42 pieces of literature that have been studied successfully. The results showed that contextual embedding as the newest text representation method considered word context and sentence meaning better than static embedding. As a classification method, the ensemble method has better performance in classifying text documents than using only a single classifier model. Thus, future research can consider using a combination of contextual embedding and ensemble methods to detect interrelationships between books of hadith.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
