Our results extend the limit law for cherries proved by Bienvenu et al. (2022). For patterns of height $1$ and $2$, we show that they either occur frequently (mean is asymptotically linear and limit law is normal) or sporadically (mean is asymptotically constant and limit law is Poisson) or not all (mean tends to $0$ and limit law is degenerate). We expect that these are the only possible limit laws for any fringe pattern.","PeriodicalId":54523,"journal":{"name":"Random Structures & Algorithms","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83529908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pemilihan guru berprestasi merupakan metode yang digunakan sebagai bentuk penghargaan kepada pekerjaannya dengan kinerja belajar mengajar selama menjadi tenaga pengajar. Adapun permasalahan dari pemilihan guru berprestasi yaitu adanya kendala dalam menentuka kriteria dan tidak tepat. Untuk itu dibutuhkan sistem pendukung keputusan (SPK) atau Decision support system yang dapat memperhitungkan kriteria yang sudah di tentukan untuk mempermudah dalam pengambilan keputusan, adapun kriteria yang di tentukan yaitu ; Nilai kehadiran, nilai disiplin, nilai kerjasama dan nilai prestasi. Sistem pendukung keputusan ini menggunakan metode simple additive weighting (SAW). Adapun tujuan dari sistem pendukung keputusan pemilihan guru berprestasi yaitu untuk mengapresiasi prestasi kerja yang telat dilakukan selama manjadi tenaga pengajar dan diharapkan dapat menambah motivasi guru dan peserta didik lainya agar lebih meningkatkan kinerja dalam belajar mengajar. Dari hasil penelitian ini dengan kesimpulan diharapkan dapat mempermudah kepala sekolah dan pengawas sekolah dalam menilai guru berprestasi berdasarkan kriteria yang telah ditentukan, serta disarankan bahwa sistem pendukung keputusan ini dapat dikembangkan dengan metode yang berbeda atau mengkombinasikan metode SAW dengan metode lain.","PeriodicalId":54523,"journal":{"name":"Random Structures & Algorithms","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79816560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilizing computer technology in the field of crowd funding, it will facilitate fundraising activities carried out by creators and providing funds by donor. Such as can be done online fundraising. Currently there are still many people who carry out manual fundraising activities which require a lot of time because they have to make documents to support fundraising and they have to approach potential donor. The possibility of losing data on donors who have provided funds is very likely because funder data is only written in a book which causes the data to become irregular. To solve the existing problem is to create a system that can store data on fundraisers and donors electronically. Computerized systems can help fundraisers (creators) and donors.

In addition, the website can also be opened via computers, laptops, smartphones, tablets, and so on. The purpose of this research is to design a system that has the Create and Read feature which will later be used by the public in reporting, to design a website public complaint system so that information sent by the public to the government is fast and accurate, based on a website-based public complaint system located on the website. In it there is a feature that can send an email to notify that the information provided by the public has been received, or it is resolved with the SMTP feature which later on the public can find out the complaint process. The system made is web-based using the Laravel framework, the system is made based on the public complaint system, consisting of people who can upload and send complaints to the government as well as people who see the status of their complaints, besides that there are admins who can view and process complaints, can add officers, and can print report data in the form of pdf. Officers can only view and process complaints and can print report data in the form of pdf, where users of this system are admins and officers from government and the community are users.","PeriodicalId":54523,"journal":{"name":"Random Structures & Algorithms","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90559101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The previous research showed that Naïve Bayes algorithm has high accuracy value. Accuracy value obtained prove that the Naïve Bayes has good accuracy percentage. Thus this algorithm can predict graduating students of SMK Buddhi Tangerang in terms of determining the predicate obtained. This research used the Naïve Bayes algorithm and MLP in knowing the pattern of these variables. Testing was done by Confusion Matrix.

Oleh karena itu, dilakukan penelitian serta perancangan sebuah aplikasi yang dapat mengklasifikasi penerima beasiswa dengan metode klasifikasi, serta menggunakan C4.5 sebagai algoritmanya. Tujuan dari penelitian ini adalah melakukan implementasi klasifikasi dengan algoritma C4.5 ke dalam sebuah aplikasi berbasis web yang diharapkan dapat membantu SD Maria Mediatrix dalam menentukan penerima beasiswa, yaitu dengan mengumpulkan data siswa yang akan digunakan sebagai dataset. Dataset tersebut kemudian dilakukan pengambilan sampel data untuk keperluan perhitungan manual. Proses perhitungan secara manual berfungsi untuk mengetahui alur dari perhitungan agar dapat diimplementasikan dengan baik pada aplikasi yang akan dibuat. Aplikasi berbasis web yang dihasilkan melakukan proses perhitungan C4.5 dan pembentukan aturan klasifikasi secara otomatis dari data siswa yang dimasukkan, pengguna aplikasi cukup menginput nama siswa, penghasilan ayah, penghasilan ibu, pemegang KIP, jumlah saudara, dan jarak rumah hasilnya akan mengetahui siswa tersebut layak mendapat beasiswa atau tidak.","PeriodicalId":54523,"journal":{"name":"Random Structures & Algorithms","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89613712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
