Abstract

Nowadays, topic of wavelet has many applications including image denoising. Wavelet Transform is divided into discrete wavelet transform and continuous wavelet transform. Besides for image denoising, it can also useful for image compression and others. In this research is discussed about steps image denoising using wavelet. Wavelets that used are Haar, Daubechies, biorthogonal, symlets and coiflets wavelets for hard thresholding and soft thresholding. Program is made according to steps/algorithm that were created. Then, we compare original image and result of image denoising. In this research, we use grayscale test image Lena and cat with size pixels. We use peak signal to noise ratio (PSNR) to measure performance of the algorithm. We also compare computational time.

Abstract

Regression analysis is a statistical method used to determine the effect of the dependent variable on the independent variable. The aim of regression analysis is to obtain an estimated model of regression model parameters from data. One of the methods used to estimate regression parameters is the MKT method (Least Squares Method). This method is not appropriate to use on data that contains outliers. Therefore, we need an alternative method that is robust to the presence of outliers, namely robust regression. In this study, the robust method used is robust regression, MM estimation, M estimation, and LTS estimation. The aim of this research is to compare the three estimation methods and select the best estimation model based on the coefficient of determination and mean square error. The case study in this research is rice production data in Sekaran sub-district with the dependent variable being rice production, the independent variables land area, productivity and population. The results of the research show that the Least Trimmed Square (LTS) robust regression method is the method that produces the best model, because the Least Trimmed Square (LTS) method has a greater determination value and a smaller Mean Square Error (MSE) compared to the MM estimation and M estimation methods.

Abstract

Surah Al-Waqiah is believed to contain many virtues, among others, it will bring abundant sustenance and avoid poverty and destitution for its readers.  Therefore, many Muslims interact directly with it. At Al-Mawaddah Islamic Boarding School in Kudus, this interaction is embodied in the tradition named with Mujahadah Waqiah. The article aims to find out the classification of reception for residents of Al-Mawaddah as readers Surah Al-Waqiah in Mujahadah Waqiah. Using a descriptive qualitative approach, the research draws on field data collected through semi-structured interviews, non-participant observation, and documentation from caregivers, teachers, students, and community members involved in the tradition. The collected data is interpreted based on Stuart Hall's reception theory.  Based on the theory, there are two classifications the residents of Al-Mawaddah receipt Surah Al-Waqiah in Mujahadah Waqiah. Some are the dominant readers, but most of them are negotiation readers. This latest finding further confirms the theory that readers are not passive, but active. Interest factors, individual experiences, and social relations play a very important role in the reception process of the residents of the Al-Mawaddah Islamic Boarding Scholl in Kudus towards Surah Al-Waqiah.Surah Al-Waqiah diyakini mengandung banyak keutamaan, antara lain, akan mendatangkan rezeki yang melimpah dan terhindar dari kefakiran dan kemiskinan bagi pembacanya. Oleh karenanya banyak orang Islam yang berinteraksi langsung dengannya. Interaksi warga Pesantren Al-Mawaddah di Kudus dengan Surah Al-Waqiah diimplementasikan dalam tradisi Mujahadah Waqiah. Artikel bertujuan mengetahui klasifikasi resepsi warga Pesantren Al-Mawaddah Kudus sebagai pembaca Surah Al-Waqiah dalam Mujahadah Waqiah.  Artikel ini merupakan hasil penelitian lapangan dengan pendekatan deskriptif kualitatif. Sumber datanya berasal dari para pengasuh, guru, santri, juga masyarakat sekitar yang terlibat dalam tradisi tersebut. Pengumpulan data dilakukan melalui wawancara semi terstruktur, observasi non-partisipatoris, dokumentasi. Data yang terkumpul diinterpretasikan berdasarkan teori resepsi Stuart Hall. Berdasarkan teori Hall, ditemukan 2 (dua) klasifikasi warga pesantren Al-Mawaddah dalam meresepsi Surah Al-Waqiah pada Mujahadah Waqiah. Sebagian sebagai pembaca dominan, namun sebagian besar mereka menjadi pembaca negosiasi. Temuan terakhir ini semakin menegaskan teori bahwa pembaca bukankah pihak yang pasif, tetapi aktif. Faktor kepentingan, pengalaman individual, relasi sosial sangat berperan dalam proses resepsi warga Pesantren al-Mawaddah Kudus terhadap Surah  Al-Waqiah.

Abstract

The fixed point is useful not only to solve problems in linear equation and differential equation, but also integral equation. The fixed point theorem of Hardy is generalization of the fixed point theorem of Reich. The metric space can be generalized to other spaces. b-metric space is one of generalization of metric space. Axiom of triangle inequality in metric space is not the same as axiom of triangle inequality in b-metric space. In this research, we discuss about fixed point theorem of Hardy in metric space. Besides that, we also discuss about fixed point of Hardy in complete b-metric space. Before proving that theorem, we prove lemma that supports the proof of theorem. We prove not only existance, but also uniqueness of fixed point from a function defined in complete b-metric space.

Abstract

Long beans (Vigna sinensis L.) are a type of vegetable crop that has been cultivated for a long time and is one of the plants that are widely consumed by the people of Indonesia One of the barriers to the productivity of long beans is pest attacks. One of the efforts made by farmers to control pests is by using insecticides. Conventional pest control began to be abandoned and switched to control based on the concept of PHT to reduce the negative impact of the use of pesticides by using yellow trap trap media. This study aims to determine the diversity of insects, this study identifies insects on long bean farmland that are interested in the color of traps that have been installed in 5 places systematically. The diversity of insects found in this study is 20 families. It consists of Chrysomelidae, Coccinellidae, Scarabidae, Reduvidae, Alydidae, Satyridae, Blattellidae, Tachinidae, Agromyzidae, Drosophildae, Tephritidae, Muscidae, Acrididae, Ichneumonidae, Formicidae, Braconidae, Cicadellidae, Aphididae, Pyralidae, and Pentatomidae. The value of the insect diversity index (H') in semi organic is 2.50 and anorganic is 2.58. The dominance on semi organic is 0.101 and anorganic is 0.103 which means low. This shows that the land has a variety of insect species and no insect species dominate.

Abstract

The era of disruption marked by the rapid development of technology and information brings serious challenges to the world of education, especially in shaping the faith and morals of students. Islamic Religious Education (PAI) has a strategic role in protecting students from the negative influences of this era, through strengthening faith in Allah SWT as the main foundation for character formation. This study aims to analyze the urgency of faith in shaping the faith and morals of students in the midst of the flow of disruption. The approach used is qualitative with a literature study method, reviewing various scientific literature, journals, and relevant documents. The results of the study show that strong faith is the main driver in the commendable behavior of students and a shield against moral relativism and social deviation. Religious education must be integrated comprehensively into the curriculum, teacher training, and learning environments that support the internalization of divine values. In conclusion, strengthening faith in Allah is very urgent as a basis for forming strong faith and morals in facing the challenges of the era of disruption.

Abstract

Survei kesehatan masyarakat merupakan komponen vital dalam upaya deteksi dini, pencegahan, dan pengendalian penyakit, terutama di era globalisasi dengan risiko penyebaran penyakit yang semakin kompleks. Studi literatur ini bertujuan menganalisis pelaksanaan surveilans kesehatan di Puskesmas wilayah Jawa, dengan fokus pada tantangan dan solusi yang dihadapi. Metode penelitian menggunakan tinjauan literatur dari jurnal terindeks Scopus, Sinta, dan Google Scholar tahun 2020–2025, dengan kata kunci terkait surveilans kesehatan di Puskesmas. Hasil kajian menunjukkan tiga masalah utama: (1) keterlambatan pelaporan akibat kurangnya pemahaman petugas, sarana komunikasi terbatas, dan partisipasi fasilitas kesehatan yang rendah; (2) keterbatasan SDM surveilans, termasuk pelatihan tidak memadai, beban kerja ganda, dan kurangnya tenaga terlatih; serta (3) lemahnya koordinasi lintas sektor antara Puskesmas, Dinas Kesehatan, dan laboratorium, yang berdampak pada ketidaklengkapan data dan respons lambat terhadap wabah. Meskipun regulasi (seperti PMK No. 45 Tahun 2014) dan platform digital (SKDR, NAR) telah tersedia, implementasinya terkendala infrastruktur dan kapasitas SDM. Solusi yang diusulkan meliputi peningkatan pelatihan tenaga surveilans, integrasi sistem informasi kesehatan berbasis teknologi, dan penguatan jejaring kolaborasi antarinstansi. Dengan langkah-langkah tersebut, sistem surveilans diharapkan dapat lebih efektif mendukung pengambilan keputusan berbasis data dan pencapaian tujuan SDGs di sektor kesehatan.
