Budidaya mangrove merupakan salah satu upaya untuk meminimalisir kerusakan ekosistem laut dan lingkungan sekitarnya saat terjadi tsunami. Eksistensi ekosistem mangrove perlu dijaga dan dilestarikan secara berkelanjutan. Kepiting Uca memiliki peranan penting pada rantai makanan yang berlangsung dalam ekosistem mangrove. Penelitian ini bertujuan mengkaji interaksi antara populasi mangrove dan populasi kepiting Uca dalam ekosistem mangrove melalui pendekatan model matematika. Kami memperoleh empat titik kritis dari model yang telah dibangun. Tiga titik kritis dari model matematika eksis tanpa syarat, namun tidak stabil. Sedangkan titik kritis keempat yang menggambarkan kondisi koeksistensi populasi mangrove dan kepiting Uca dapat dijamin kestabilan lokalnya jika syarat kestabilannya terpenuhi. Hal ini mengindikasikan bahwa kehadiran populasi kepiting Uca dapat menjaga kelestarian ekosistem mangrove. Simulasi numerik diberikan untuk mendukung hasil analitik.

Inflation is a very important indicator in maintaining the stability of the country's economy, so it is necessary to predict the inflation rate to determine the movement of the inflation rate in the future. To predict the inflation rate in Indonesia in 2023, this research uses the Average Based Fuzzy Time Series (FTS) method based on Python programming. This method uses the principle of fuzzy set as the basis of its calculation. The data used in this study are monthly data on inflation rates in Indonesia for the period January 2013 - December 2022 obtained from the official website of Bank Indonesia (BI). The results showed that the prediction of the inflation rate in Indonesia in 2023 was in the range of 5.23% - 5.51% with the highest inflation value occurring in April and the lowest inflation value occurring in January. The accuracy level of the Average Based FTS method is calculated using the Mean Absolute Percentage Error (MAPE) of 0.820849835% which indicates that the method can be used to predict the inflation rate. Keywords : Average Based, FTS, Inflation, Prediction, Python

NU as the largest Islamic organization in the world, one of its functions is to empower in the economic field in order to realize economic development and equity, and provide equal opportunities to enjoy the results of development. The spirit of this movement certainly cannot be separated from the spirit of Nahdlatut Tujjar as one of the embryos of the birth of NU, where this organization was formed one of the goals was to give birth to Muslim entrepreneurs to solve the economic problems felt by the community at that time. In practice, the NU populist economic movement is carried out, among others, through LPNU as an institution that concentrates on the economic field, where the East Java LPNU has specifically formulated a grand design in empowering MSMEs through the NUCONOMIC movement. This article is a study of the NUCONOMIC program as a grand design of the East Java Nahdlatul Ulama Economic Institute (LPNU) in empowering MSMEs which is focused on two main problems: (1) how is the implementation of NUCONOMIC in empowering MSMEs in East Java LPNU? (2) what are the challenges and opportunities for the NUCONOMIC movement of East Java LPNU in empowering MSMEs? This research uses qualitative methods with an ethnographic approach. Data collection techniques are carried out by means of observation, interviews, and documentation. The results of this research show that the grand design of the NUCONOMIC program is carried out with five stage processes, namely: (a) Training; (b) Assistance; (c) Exhibitions; (d) Technology; and (e) Monev.

Penelitian ini bertujuan untuk mengidentifikasi keanekaragaman jenis rumput, legume, dan rumba di area persawahan serta perkebunan pisang di Kelurahan Baruga, Kota Kendari, dengan menggunakan teknologi GIS. Analisis data dilakukan secara deskriptif berdasarkan jumlah spesies, frekuensi, dominansi, indeks keanekaragaman, dan komposisi botani. Hasil penelitian menunjukkan bahwa di area persawahan, rumput yang dominan adalah Digitaria ciliaris Retz (0,15%), sedangkan di perkebunan pisang Brachiaria (0,26%) lebih mendominasi. Jenis legume utama di sawah adalah Ilysanthes (0,38%), sementara di perkebunan pisang adalah Rungia Pectinata (0,50%). Untuk kategori rumba, Phyllantus minuri (0,28%) mendominasi di sawah, sedangkan Orlandia costata (0,24%) lebih banyak ditemukan di perkebunan pisang. Komposisi botani yang diperoleh menunjukkan kualitas padang penggembalaan, yang dapat dimanfaatkan sebagai sumber hijauan pakan ternak. Pemanfaatan teknologi GIS membantu peternak dalam mengidentifikasi dan mengelola hijauan secara lebih efektif, sehingga dapat mendukung ketersediaan pakan untuk ternak ruminansia.

Penelitian ini penting karena standar Nomor Kontrol Veteriner (NKV) yang ada saat ini terlalu tinggi dan tidak sesuai untuk Rumah Pemotongan Unggas Skala Kecil (RPU-SK), yang sering memiliki keterbatasan sarana dan prasarana. Tanpa penyesuaian standar yang relevan, praktik biosekuriti dan higiene di RPU-SK akan kurang memadai, yang berpotensi menimbulkan risiko kesehatan masyarakat melalui daging unggas yang kurang aman. Untuk mengidentifikasi dan mengatasi hal tersebut, penelitian ini bertujuan untuk memastikan jaminan keamanan pangan yang lebih baik dan mendukung keberlanjutan industri pemotongan unggas lokal. Tujuan penelitian ini bertujuan untuk mengembangkan checklist biosekuriti dan higiene yang disesuaikan khusus untuk RPU-SK berdasarkan penilaian kesenjangan antara standar NKV dan kondisi nyata di lapangan. Checklist ini diharapkan dapat diterapkan secara efektif di RPU-SK untuk meningkatkan kepatuhan terhadap praktik biosekuriti dan higiene, memastikan daging unggas yang aman dan sehat, serta meningkatkan pengetahuan dan keterampilan peternak dan teknisi di sektor ini. Metode penelitian dilakukan melalui pendekatan kualitatif dengan pengamatan langsung dan wawancara di RPU-SK di Kota Kendari. Checklist biosekuriti dan higiene yang ada akan dinilai dan disesuaikan berdasarkan standar NKV untuk menciptakan versi yang lebih relevan dan praktis. Evaluasi akan mencakup identifikasi kesenjangan antara standar dan praktik saat ini, diikuti dengan penerapan checklist yang baru dikembangkan pada RPU-SK. Penelitian ini menunjukkan bahwa sebagian besar RPU-SK di Kota Kendari memiliki masalah biosekuriti dan higiene, seperti ketiadaan fasilitas pencucian tangan, pendinginan karkas, dan pengelolaan limbah yang buruk. Hal ini meningkatkan risiko kontaminasi mikroba pada produk unggas dan pencemaran lingkungan. Untuk memperbaiki kondisi ini, diperlukan regulasi ketat, peningkatan infrastruktur, pelatihan pekerja, dan pengelolaan limbah yang lebih baik.

This study investigates the influence of product visual quality, with a specific focus on product thumbnails, on consumer purchasing behavior across two leading e-commerce platforms in Indonesia. Employing a quantitative methodology using Partial Least Squares Structural Equation Modeling (PLS-SEM), data were gathered from 150 active online shoppers in South Sulawesi. The findings demonstrate that product visual quality exerts a significant, direct impact on consumer purchasing behavior, emphasizing that clear and appealing visuals foster consumer trust and mitigate perceived risks. Furthermore, the visual quality of thumbnails not only enhances the perceived value of products but also bolsters the overall credibility of the platform, serving as both informational cues and trust signals. These results corroborate the Stimulus-Organism-Response (S-O-R) framework, demonstrating that high-quality visual function serves as a stimulus that influences consumer perceptions and purchasing intentions. This research contributes to the expanding body of digital marketing literature by reaffirming that visuals are not merely decorative elements but are essential in motivating online purchasing behaviors. Practical implications advise e-commerce managers to prioritize consistent, high-resolution imagery and an intuitive platform design to sustain consumer confidence and boost sales conversions.
