Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh pemberian berbagai dosis pupuk NPK mutiara dan FMA terhadap pertumbuhan dan produksi tanaman cabai merah keriting pada tanah PMK. Rancangan penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor pemberian pupuk NPK dengan variasi dosis 0g/tanaman, 10 g/tanaman, 20 g/tanaman, 30 g/tanaman, dan 40 g/tanaman, dan pemberian mikoriza dengan variasi 0g/tanaman dan 5g/tanaman. Data diolah dengan menggunakan analisis sidik ragam (ANOVA). Hasil penelitian menunjukkan bahwa pemberian pupuk NPK berpengaruh nyata terhadap pertumbuhan dan produksi tanaman cabai keriting sedangkan pemberian FMA dan interaksi perlakuan tidak berpengaruh nyata terhadap semua variabel yang diamati. Penelitian ini merekomendasikan pemberian pupuk NPK 10g/tanaman untuk pertumbuhan dan produksi maksimal tanaman cabai keriting.Growth Response and Yield of Curly Red Chili (Capsicum Annuum L.) due to the Application of Nitrogen-Phosphorus-Potassium Fertilizer and Fungi Mycorrhiza Abruskala in Red-Yellow Podzolic SoilAbstract.The prospects for the development of curly red chilies are very bright because consumer demand during holidays always cannot be fulfilled by the market. Red-yellow podzolic (PMK) soil is a type of soil with low productivity due to intensive leaching and advanced weathering. To support the growth and production of curly chili plants, nitrogen-phosphorus-potassium (NPK) and arbuscular mycorrhizal fungi (FMA) fertilizer can be used. The aim of this research was to determine the effect of giving various doses of NPK granular fertilizer and FMA on the growth and production of curly red chili plants on PMK soil. This research design used a Randomized Block Design (RAK) with two factors, the application of NPK fertilizer with varying doses of 0 g/plant, 10 g/plant, 20 g/plant, 30 g/plant, and 40 g/plant, and the application of FMA at a dose of 0g/plant and 5g/plant. Data were analyzed by using analysis of variance (ANOVA). The results showed that the application of NPK fertilizer had a significant effect on the growth and production of curly chili plants, while the application of FMA and interactions of the treatments had no significant effect on all the variables observed. This research recommended the use of 10g NPK fertilizer per plant for the maximal growth and production of curly chili plants.

Abstract

Abstrak. Penggilingan gabah merupakan proses pengolahan gabah kering menjadi beras dengan bantuan mesin yang dikontrol penuh oleh pekerja pada stasiun tertentu. Manusia sebagai pekerja tengah berada pada ruang penggilingan dengan banyak resiko seperti bising dan getaran yang ditimbulkan oleh mesin tersebut dan antropometri yang belum terjamin kesesuaiannya dengan pekerja yang mengoperasikan mesin tersebut sehingga perlu dikaji berdasarkan kajian ergonomika. Penelitian bertujuan untuk menganalisa antropometri mesin dengan pekerja serta lingkungan fisik untuk mengurangi resiko kerja. Metode penelitian menggunakan metode eksperimental yang dikaji langsung pada ruang penggilingan beras di Desa Batu Putik Lombok Timur. Parameter yang dikaji yaitu antropometri, tingkat kebisingan, getaran mekanis, suhu dan tingkat pencahayaan. Data hasil penelitian dianlisis menggunakan matematika sederhana dengan bantuan mikrosoft excel kemudian dibandingankan dengan Nilai Ambang Batas (NAB) pada setiap parameter. Hasil penelitian menunjukkan bahwa antropometri pada 3 stasiun yang dikaji yaitu stasiun pertama tempat gabah dimasukkan berada 200 cm artinya hopper tersebut berada di atas kepala operator, stasiun kedua output gabah pecah 50% memiliki ketinggian 92 cm dan stasiun ketiga yaitu output beras bersih siap untuk dikemas memiliki tinggi 92 cm. Sedangkan hasil analisis dari lingkungan fisik menunjukkan bahwa suhu di atas NAB dan pecahayaan di bawah NAB, sedangkan getaran mekanis dan tingkat kebisingan berada di atas Nilai Ambang Batas NAB. Sehingga dapat disimpulkan bahwa ruang produksi penggilingan gabah dapat dikatakan belum memenuhi standar ergonomika.Anthropometric and Physical Environmental Analysis of Grain Milling Rooms to Reduce Work RisksAbstract. Grain milling is the process of processing dry grain into rice with the help of machines that are fully controlled by workers at certain stations. Humans as workers are in the milling room with many risks such as noise and vibrations caused by the machine and anthropometers that are not yet guaranteed to be suitable for the workers operating the machine so this needs to be studied based on ergonomics studies. The research aims to analyze the anthropometry of machines and workers and the physical environment to reduce work risks. The research method used experimental methods which were studied directly in the rice milling room in Batu Putik Village, East Lombok. The parameters studied are anthropometry, noise level, mechanical vibration, temperature and lighting level. The research data was analyzed using simple mathematics with the help of Microsoft Excel and then compared with the threshold value (NAB) for each parameter. The results of the research show that the anthropometry at the 3 stations studied, namely the first station where the grain is inserted is 2 meters, meaning the hopper is above the operator's head, the second station, the output of 50% broken grain has a height of 92 cm and the third station, namely the output of clean rice ready to be packaged, has a height of 92 cm. cm. Meanwhile, the results of analysis of the physical environment show that the temperature is above NAB and lighting is below NAB, while mechanical vibrations and noise levels are above the threshold value NAB. So it can be concluded that the grain milling production room can be said to not meet ergonomic standard.

Abstract

Abstrak. Persemaian Eukaliptus di rumah tanaman tropis basah menghadapi tantangan suhu yang tinggi, yang dapat mencapai 37C, jauh di atas rentang suhu ideal (25-31C). Penelitian ini bertujuan untuk menganalisis efektivitas pendinginan evaporatif dalam mengontrol suhu rumah tanaman. Simulasi dilakukan menggunakan perangkat lunak Ansys Discovery pada model rumah tanaman berukuran 8 m x 4 m x 4 m dengan ventilasi di dinding dan atap. Kecepatan aliran udara yang disimulasikan bervariasi antara 0,9 m/s hingga 5 m/s. Hasil menunjukkan bahwa tanpa pendinginan evaporatif, suhu rumah tanaman cenderung serupa dengan suhu lingkungan, yang tidak mendukung pertumbuhan optimal Eukaliptus. Dengan pendinginan evaporatif, suhu di dalam rumah tanaman dapat diturunkan hingga 26-28C, terutama pada kecepatan aliran udara 3 m/s atau lebih. Sistem pendinginan evaporatif terbukti efektif dalam menyeragamkan suhu, menjadikannya solusi yang direkomendasikan untuk mendukung keberhasilan persemaian Eukaliptus di kawasan tropis basah.Simulation of Temperature Distribution by Evaporative Cooling in a Wet Tropical Greenhouse for Eucalyptus NurseryAbstract.Eucalyptus nurseries in wet tropical greenhouses face the challenge of high temperatures, which can reach 37C, well above the ideal temperature range (25-31C). This study aims to analyse the effectiveness of evaporative cooling in controlling greenhouse temperature. Simulations were conducted using Ansys Discovery software on an 8 m x 4 m x 4 m greenhouse model with vents in the walls and roof. The simulated airflow velocity varied from 0.9 m/s to 5 m/s. Results show that without evaporative cooling, the greenhouse temperature tends to be similar to the ambient temperature, which does not favour optimal growth of Eucalyptus. With evaporative cooling, the temperature inside the greenhouse can be reduced to 26-28C, especially at airflow velocities of 3 m/s or more. Evaporative cooling systems are proven to be effective in uniforming temperatures, making them a recommended solution to support the success of Eucalyptus nurseries in wet tropical regions.
