Abstract

Crop pests and diseases are limiting factors in determining crops production. Brown Plant Hopper/BPH (Nilaparvata lugens) is the major crop pests and diseases for rice in Asia since 1970?s. The presence of BPH is depending upon several conditions covering pathogenic characteristics, carriers, physical environment (rainfall, temperature, humidity etc.) and biotic environment (natural enemy, competitor organisms). BPH growth is very fast delivering huge amount of eggs, has a short life cycle (28 days) with fast distribution forces and incredible attack forces. BPH is very dynamic in their live assuming due to the climatic condition of their habitat. This is the reason why climate can be used as an indicator for early warning to anticipate the area attack of BPH especially and in general for crop pests and diseases control. The relationship between pest and diseases attack and climate parameters such as rainfall, mean temperature, maximum temperature, minimum temperature, mean humidity, maximum humidity, and minimum humidity can be analyzed using multiple regression. The early warning system is developed using software of MS Access, Arc View, Map Object, and Visual Basic that can be a dynamic and interactive system. The results of analysis showed that climate parameter has a correlation with the area attack of BPH only during the La-NiƱa years. Those parameters include rainfall, maximumtemperature, maximum temperature at two weeks before attack, minimum temperature, and minimum temperature at two weeks before attack. The early warning system is started by entering the climate prediction for the next cropping season where the time is subject to prediction, at a certain sub-district. After inputting data of climate prediction the system will provide information of potential area attack of BPH at that location. By performing information of potential area attack the anticipative action can be designed earlier so that the crops harvest failure can be reduced.

Abstract

Musculoskeletal Disorders (MSDs) merupakan sekelompok gangguan yang memengaruhi sistem otot, tendon, ligamen, saraf, kartilago, dan tulang, sehingga dapat menghambat aktivitas kerja. Penelitian ini bertujuan untuk menganalisis pengaruh lingkungan kerja, postur kerja, dan aktivitas fisik terhadap keluhan MSDs pada perawat di RSIA Kenari Graha Medika Cileungsi, Bogor tahun 2024. Metode penelitian yang digunakan adalah kuantitatif dengan desain cross-sectional. Sampel penelitian berjumlah 38 perawat yang dipilih secara purposive. Pengumpulan data dilakukan melalui kuesioner Nordic Body Map (NBM) dan lembar kerja Rapid Entire Body Assessment (REBA) dengan metode observasi. Analisis data menggunakan uji chi-square yang diproses dengan aplikasi statistik. Hasil penelitian menunjukkan bahwa sebagian perawat mengalami keluhan MSDs, yang berkaitan dengan lingkungan kerja yang kurang nyaman, postur kerja yang tidak ergonomis, serta kebiasaan aktivitas fisik yang rendah. Analisis statistik menunjukkan adanya hubungan signifikan antara lingkungan kerja (p = 0,001), postur kerja (p = 0,011), dan aktivitas fisik (p = 0,018) dengan keluhan MSDs. Oleh karena itu, disarankan agar perawat rutin melakukan olahraga minimal tiga kali seminggu untuk meningkatkan sirkulasi darah dan memperkuat otot serta tulang. Selain itu, perusahaan diharapkan mengoptimalkan kebijakan terkait senam bersama, stretching sebelum bekerja, serta pemeriksaan kesehatan berkala (MCU) guna meminimalkan risiko MSDs di tempat kerja.
