Composting is a widely used biological process for the management of some wastes produced in communities and agricultural activities, which have experienced substantial growth during the last few years. Because this and the knowledge of composting has increased, the number of composting facilities has increased tremendously, especially in some European countries. Interest has also increased in several countries in other regions of the world. This book attempts to summarize some of the most important work conducted during the last few years under one cover. The contributions to the publication are made by some of the most qualified professionals in the world and present the information in a clear and objective manner. The readers will find the information very useful and will be helpful in the design of new facilities and organic recycling programs. * Up-to-date contributions by some of the most knowledgeable and respected leaders in the field * Clear and objective presentations, which are arranged in such a way that it is not necessary to read the entire book * Information is supported by data, tables and references * Covers most important aspects of the process including a brief historical review * May be used by teachers as well as practicioners in the field.

ABSTRAK Penelitian mengenai pemanfaatan kompos Unit Pengolahan Sampah (UPS) Universitas Indonesia terhadap pertumbuhan terung ungu (Solanum melongena L. var. Lezata) dilasanakan pada bulan Oktober sampai dengan November. Penelitian dilakukan dengan tujuan untuk mengetahui komposisi kompos dalam media tanam yang paling baik untuk mendukung pertumbuhan tanaman terung. Kompos dalam media tanam divariasikan sebagai berikut P1 (tanah: pasir: kompos 1:1:0), P2 (tanah: pasir: kompos 1:1:0.5), P3 (tanah: pasir: kompos 1:1:1), dan P4 (tanah: pasir: kompos 1:1:2), serta P5 (media tanam komersil) sebagai kontrol positif. Dua fase pertumbuhan yang akan diamati yaitu vegetatif dan generatif. Data diolah berdasarkan parameter kualitatif (warna daun, bentuk daun, besar daun, warna buah dan tes organoleptik) dan kuantitatif (tinggi tanaman, jumlah daun, berat basah dan berat kering, panjang akar,jumlah buah, panjang dan berat buah). Data kualitatif menunjukkan adanya perbedaan warna daun dan warna buah tanaman terung ungu pada perlakuan media tanam. P5 dan P1 menunjukkan warna daun yang lebih terang dibandingkan dengan tiga perlakuan lainnya. Perlakuan P3 dan P4 menunjukkan warna kulit buah terung ungu yang gelap dan sesuai dengan literatur, sementara perlakuan lainnya menunjukkan warna buah ungu terang. Hasil analisis statistik menunjukkan bahwa kompos UPS UI berpengaruh nyata terhadap parameter tinggi tanaman, jumlah daun, berat basah, berat kering tanaman, dan jumlah bunga tanaman. Namun, kompos UPS UI tidak berpengaruh nyata terhadap panjang akar dan jumlah buah. Kombinasi terbaik untuk pertumbuhan vegetatif ditunjukkan oleh P3. Perlakuan P3 dan P4 menunjukkan hasil yang hampir serupa pada hasil pertumbuhan generatif.

ABSTRACT Research on the use of UPS UI compost on the growth of purple eggplant (Solanum melongena L. var. Lezata) was conducted from October to November. The research was conducted with the aim to find out the proportion of compost in the growing media to support the growth of eggplant plants. Compost in the planting medium is varied as follows P1 (soil: sand: compost 1: 1: 0), P2 (soil: sand: compost 1: 1: 0.5), P3 (soil: sand: compost 1: 1: 1), and P4 (soil: sand: compost 1: 1: 2), and P5 (commercial growing media) as a positive control. Two growth phases will be observed, vegetative and generative. Data were processed based on qualitative parameters (leaf color, stem color, leaf shape, leaf size, fruit shape, fruit color and organoleptic tests) and quantitative (plant height, number of leaves, wet weight and dry weight, root length, and number of fruits, fruit length and weight). Qualitative data shows the differences in leaf color and fruit color of purple eggplant plants in the planting media treatment. P5 and P1 showed lighter leaf color compared to the other three treatments. Treatments P3 and P4 showed dark purple eggplant skin color and according to the literature, while other treatments showed light purple fruit color. Statistical analysis showed that UPS UI compost significantly affected the parameters of plant height, number of leaves, wet and dry weight. However, UPS UI compost has no significant effect on root length and number of fruits. The best combination for plant vegetative growth shown by P3. P3 and P4 shows an almost similar result in generative growth .
