Judul: Pengelolaan Proses Produksi dan Pasca Panen Selada (Lactuca sativa L.) Secara Aeroponik dan Hidroponik Deep Flow Technique di Amazing Farm, Lembang, Bandung.
Abstrak: Vegetables are needed by human being as their consumption to fulfill their daily nutrition, that’s why the opportunity of vegetables production is widely opened to be developed. This opportunity drives people to use the suitable technique to gain optimum production as well as the quality, quantity and continuity, such as using aeroponic and hydroponic system. The internship was implemented in Amazing Farm, Field Cikahuripan 1, Lembang, Bandung. Amazing farm is one of the leading companies in horticultural products. The purposes of the internship were to get working experience and practical knowledge about production of aeroponic and hydroponic lettuce (green curly, lollorossa and romaine), discover the difference between aeroponic and hydroponic system, get management and post harvest experience and also help the company to solve problems in cultivation technique. Aeroponic system can produce lettuce crop better than hydroponic does. The post harvest observation of aeroponic and hydroponic lettuce didn’t show significant diference. The business analysis of lettuce production shows that aeroponic lettuce is more promising than hydroponic, although it needs large amount of capital for the investment.

Judul: Life Cycle Assessment Software for  Hydroponic Lettuce Cultivation at Greenhouse
Abstrak: Produksi selada di Indonesia mengalami peningkatan setiap tahunnya sehingga perlu didukung dengan penerapan berbagai metoda budidaya, salah satunya hidroponik. Proses budidaya tanaman secara hidroponik dalam greenhouse berpotensi menimbulkan dampak negatif bagi lingkungan berupa limbah padat, cair, maupun gas. Salah satu cara yang dapat digunakan untuk mengendalikan dampak lingkungan tersebut adalah dengan menerapkan Life Cycle Assessment (LCA). LCA merupakan metode penilaian dampak lingkungan yang proses pencatatan data dan perhitungannya masih banyak dilakukan dengan spreadsheet excel dan kurang efektif, sehingga dibutuhkan sistem untuk pendataan serta perhitungan dampak emisi. Tujuan penelitian ini adalah membuat rancang bangun website LCA untuk budidaya selada secara hidroponik di greenhouse serta menginterpretasikan hasil yang didapat. Tahapan pada penelitian ini meliputi analisis LCA dan analisis kebutuhan sistem, desain, implementasi, dan pengujian. Hasil dari penelitian ini berupa sebuah website yang dapat diakses oleh pengguna untuk keperluan inventory dan perhitungan dampak lingkungan yang dihasilkan selama proses budidaya tanaman. Sistem juga dapat menampilkan interpretasi hasil perhitungan dalam bentuk grafik batang dan grafik pie., Lettuce production in Indonesia has increased every year so it needs to be supported by the application of various cultivation methods, one of which is the hydroponic. The process of hydroponic cultivation of plants in the greenhouse has the potential to cause negative impacts on the environment in the form of solid, liquid, and gas waste. One way that can be used toendavert these environmental impacts is to apply a Life Cycle Assessment (LCA). LCA is an environmental impact assessment method whose process of collecting data records and calculations is still widely carried out with excel spreadsheets and is less effective, so a system is needed for data collection and emission impact calculations. The purpose of this study was to design and build an LCA website for hydroponic lettuce cultivation in the greenhouse and interpret the results obtained. The stages of this study include LCA analysis and analysis of system needs, design, implementation, and testing. The results of this study are in the form of a website that can be accessed by users for inventory purposes and calculation of environmental impacts produced during the plant cultivation process. The system can also display the interpretation of the calculation results in the form of bar graphs and pie graphs.

Abstrak: The t modified 2 test is more robust than t test for skewed popnlation. This test tolerate the population skewness from -1.2 to 1.2 sample size is reather than 25. The sign test robust to the populated skewed population, but the value of the estimated always close to the size of the tcst. Wilcoxon test is not robust to the population skewness. This test is more suittalble for Symmetric population
