Drone Spray for Base Rot Disease Detection in Oil Palm Plants aims to increase the effectiveness of disease detection and control using drone technology. Stem base rot disease, caused by the fungus Ganoderma boninense, threatens oil palm productivity in Indonesia. Drone technology with near-infrared (NIR) sensors and image processing is used to detect early signs of the disease, enabling timely preventive action. A drone equipped with a Raspberry Pi camera and NoIR V2 pro-duces high-resolution images for NIR reflectance analysis. The research included field observations, expert interviews, and sensor data collection for evaluation of the effectiveness of this technology. Results show that the use of drones can in-crease disease detection efficiency by 85%, reduce operational costs, and minimize health risks for workers. This drone technology has great potential to improve the productivity and sustainability of the palm oil industry in Indonesia. This research recommends the adoption of drone technology in the agricultural sector to address plant disease challenges more efficiently and effectively.

Fly density is an indicator of environmental sanitation assessment. Fly density is influenced by waste management, the National Waste Management Information System (SIPSN) shows that waste generation in Jambi City reaches 159,688.01 tons/year. The aim of this research is to determine factors related to the level of fly density in Temporary Waste Storage Sites (TPSS) in Telanaipura District, Jambi City 2023. This research is a quantitative research with a cross sectional method research design. This research was conducted in the Telanaipura District community with a sample of 94 people. Data analysis was carried out using univariate and bivariate methods using correlation tests. The results of this study indicate that knowledge (p=0.027), action (p=0.029), monitoring (p=0.017), sorting (p=0.016), collection (p=0.027), and transportation (p=0.026) have relationship with the level of fly density, while attitude (p=0.245) had no relationship with the level of fly density. Knowledge, action, monitoring, sorting, collection and transportation are factors related to the level of fly density in temporary waste storage sites in Telanaipura District. It is hoped that the public will pay attention to managing household waste properly.

The effect of fiscal decentralization financing sources (PAD, DP, PL) on poverty levels in Jambi Province is 80.2%, while the remaining 19.8% is influenced by other factors not included in this study. And there is a strong relationship between fiscal decentralization and poverty levels of 89.6%.

Customer segmentation plays a pivotal role in driving marketing strategies and improving customer retention across various industries. This study explores the application of the RFM (Recency, Frequency, Monetary) model for customer segmentation in a Software-as-a-Service (SaaS) business, using Python for efficient data processing and analysis. By analyzing one year of customer purchase data, we segmented customers into key groups such as "Champions," "Loyal Customers," and "At Risk." The results highlight that targeted discount strategies significantly affect profitability, especially for high-value customer segments. Furthermore, the research builds upon existing methodologies, demonstrating how Python-based implementations streamline RFM analysis and allow for scalable solutions in business contexts, as illustrated in prior works by Hermawan et al. (2024). This study offers actionable recommendations, including tailored discounting, loyalty programs, and personalized engagement strategies, to enhance customer retention and business profitability. The findings underscore the importance of data-driven marketing approaches for customer segmentation and engagement, reinforcing the relevance of the RFM model in modern business environments.

Performance at the PUPR District Office Tanah Datar has not reached the target for 4 years. This study aims to examine the Effect of Placement and Work Environment on Employee Performance with Job Satisfaction as an Intervening Variable using secondary data obtained by distributing questionnaires to 50r6 permanent employees who are used as respondents at the PUPR DINAS Office of Tanah Datar Regency. In this study using the analysis tool Structural Equation Modeling (SEM) using Partial Least Square (PLS). The results of this study indicate that (1) Placement has a positive and significant effect (0.000 <0.05) on job satisfaction. (2) Work environment has a positive and significant effect (0.000 <0.05) on job satisfaction. (3) Placement has a positive and significant effect (0.027 > 0.05) on Employee Performance. (4) Work Environment has no effect (0.237 <0.05) on Employee Performance. (5) Job satisfaction has a positive and significant effect (0.004 <0.05) on employee performance. (6) Placement has an effect and significant (0.035 <0.05) on Employee Performance through Job Satisfaction. (7) Work Environment has a positive and significant effect (0.012 <0.05) on Employee Performance through Job Satisfaction. (8) The contribution of placement and work environment variables to employee performance is 0.865 or 86.5% and the remaining 13.5% is influenced by other variables not examined in this study. (9) The contribution of placement, work environment and job satisfaction variables to employee performance is 0.871 or 87.1% and the remaining 12.9% is influenced by other variables not examined by this study.

Angklung merupakan sebuah alat musik tradisional yang terbuat dari bambu, yang dimainkan secara berkelompok dengan cara digetarkan, mencerminkan kebutuhan akan sinkronisasi dan kerjasama di antara para pemain. Angklung menjadi simbol kearifan lokal, sarana hiburan, memegang nilai budaya dan sejarah yang mendalam dalam masyarakat Sunda, serta memiliki peran penting sebagai warisan budaya Indonesia. Permasalahannya, di era modern ini, upaya pelestarian terhadap angklung yang adaptif belum dimiliki oleh masyarakat secara keseluruhan.  Penelitian ini bertujuan untuk mengkaji upaya pelestarian angklung yang telah dilakukan, khususnya di Jawa Barat, dari masa lalu hingga saat ini. Dengan metode deskriptif kualitatif dengan sampel angklung yang dibuat dari saung Mang Udjo di Bandung. Hasil dari penelitian ini menunjukkan bahwa angklung tetap bertahan serta dilestarikan sebagai warisan budaya indonesia, dapat digunakan dalam kehidupan sosial budaya, dan upaya pelestarian yang dilakukan telah berhasil menjaga nilai budaya angklung dalam masyarakat.

Semakin menurunnya kecepatan dan tingkat pemanfaatan inovasi teknologi pertanian yang dihasilkan oleh Badan Penelitian dan Pengembangan Pertanian (Balitbangtan) menjadi tanda tanya yang harus terjawab melalui riset yang relevan. Untuk itu, perlu untuk dianalisis faktor-faktor yang mendukung kinerja penyuluh berdasarkan karakteristik personal penyuluh dan dukungan eksternal penyuluh. Penelitian ini merupakan penelitian survei dengan menggunakan pendekatan kuantitatif. Analisis data menggunakan Teknik analisis Korelasi Rank Spearman. Hasil penelitian membuktikan bahwa terdapat hubungan yang signifikan antara karakteristik responden dengan kinerja penyuluh pertanian di kabupaten Kutai Kartanegara. Nilai koefisien korelasi sebesar 0,469 dimaknai sebagai korelasi positif atau searah. Artinya semakin baik karaktersitik personal penyuluh (pendidikan formal, frekuensi mengikuti pelatihan, dan disiplin ilmu) maka semakin tinggi kinerja mereka ataupun sebaliknya. Tingkat keeratan hubungan antara variabel karakteristik personal dengan kinerja penyuluh pertanian berada pada kategori Sedang.
