Quality performance greening material of moss was pursued based L*a*b* color scale and RGB index. The research objective is to test the quality of performance greening material of moss based on temperature parameters. Then determine the optimum point temperature greening material of moss in a controlled environment by color change parameters. The research was pursued by testing a prototype greening material of moss (sphagnum sp) in confined space, three treatment temperature are average temperature 28 ±20C, high temperature 33±20C and 38±20C as the extreme temperature, with 500 ml water stream for 2160 minutes and without watering for 1440 minutes. Indications of quality performance can be seen by L*a*b* and RGB color change. The results were confirmed by using photosynthesis rate. The best performance is in the extreme temperature treatment by flushing, with 34.71% of G index. The research concluded has satisfied quality performance greening material of moss in maximum.ABSTRAKKualitas performansi greening material lumut diyakinkan berdasarkan skala warna L*a*b* dan indeks RGB. Tujuan penelitian yaitu untuk pengujian performansi mutu tumbuhan lumut dalam prototipe greening material berdasarkan parameter suhu. Kemudian menentukan titik optimum suhu greening material lumut dalam sistem lingkungan terkendali dengan parameter perubahan warna. Penelitian ini dilakukan dengan menguji prototipe greening material lumut (sphagnum sp) pada confined space, dengan tiga perlakuan suhu yaitu suhu rata-rata 28±20 C, suhu tinggi 33±20 C dan suhu ekstrim 38±20C dengan penyiraman air 500ml selama 2160 menit dan tanpa penyiraman selama 1440 menit. Indikasi performansi mutu dilihat dari perubahan warna Lab dan RGB yang didukung dengan laju fotosintesis tumbuhan lumut. Hasil performansi paling optimum yaitu pada perlakuan suhu ekstrim dengan penyiraman dengan indeks G 34.71%. Kesimpulan dari eksperimen ini bahwa kualias yang paling memuaskan dari kinerja mutu prototipe greening material lumut pada perlakuan suhu maksimal.

Separation of nutmeg based on quality at the farm level is still not done. At the market level process to separate the whole seed and seed damage done by direct observation. The process has the disadvantage, among others, can not be done continuously and mixed results. Development of non-destructive method for separate nutmeg by class quality effectively and objectively indispensable. On image texture analysis can be used to differentiate the surface properties of an object in the image associated with the rough and smooth, also the specific properties of the surface roughness and smoothness criteria that characterize an object of an object. This study aims to analyze the texture characteristics of the object image nutmeg with image processing to determine the quality grade of nutmeg. The materials used are nutmeg derived from Ternate town of North Maluku with reference to defined quality standards in 2000 that divides Menegristek nutmeg into three quality classes ABCD, Rimpel and BWP. Determination of the quality criteria nutmeg done by the method of discriminant analysis. Texture characteristics extracted from the object image consisting of nutmeg contrast, correlation, energy, homogenity, entropy. The results showed significant parameter correlation and the entropy distinguish quality classes nutmeg with a degree of truth of 96,7%.ABSTRAKPemisahan biji pala berdasarkan mutu di tingkat petani saat ini masih belum dilakukan. Di tingkat pedagang proses untuk memisahkan antara biji utuh dan biji rusak dilakukan dengan pengamatan langsung. Proses tersebut memiliki kelemahan antara lain tidak dapat dilakukan secara terus menerus dan hasil yang beragam. Pengembangan metode non-destruktif untuk memisahkanan biji pala berdasarkan kelas mutunya secara efektif dan objektif sangat diperlukan. Analisis tekstur pada citra dapat digunakan untuk membedakan sifat-sifat permukaan suatu benda dalam citra yang berhubungan dengan kasar dan halus, juga sifat-sifat spesifik dari kekasaran dan kehalusan permukaan suatu objek yang mencirikan kriteria suatu objek. Penelitian ini bertujuan menganalisis ciri tekstur dari citra objek biji pala dengan pengolahan citra untuk menentukan kelas mutu pala. Bahan yang digunakan adalah biji pala yang berasal dari kota Ternate Maluku Utara dengan mengacu pada standar mutu yang ditetapkan Menegristek tahun 2000 yang membagi biji pala kedalam tiga kelas mutu ABCD, Rimpel dan BWP. Penentuan kriteria mutu pala dilakukan dengan metode analisis diskriminan. Ciri tekstur yang diekstrak dari citra objek biji pala terdiri dari kontras, korelasi, energi, homogenitas, entropi. Hasil penelitian menunjukan parameter korelasi dan entropi signifikan membedakan kelas mutu pala dengan tingkat kebenaran sebesar 96,7%.

The vegetables should be cultivated in an optimal way to obtain maximum yield. In tropical regions such in Indonesia, the growth of vegetables are influenced by climate factors such as humidity, temperature, nutrients and light. To gain the optimal and controlled condition during the growth periode, mustard plants could be cultivated hydroponically in a greenhouse. This study was conducted to identify the growth pattern of mustard (Brassica rappa var. Parachinensis L.) that hydroponically planted in a greenhouse which is equipped with a temperature, nutrients and light control. The aim of this research is to determine the best factors combination that provide the most optimum growth. This research was conducted by three treatments that were temperature, nutrition, and light. Each of the treatment has three variations : temperature (32 °C, 35 °C, and 38 °C), nutrition (2 mS/cm, 5 mS/cm, and 8 mS/cm), and light (7000 lux, 12000 lux, and 17000 lux) so there were 27 cultivation spaces or greenhouses used with different micro-climates. The growth rate was determined by the area of the leaf and it was measured during 48 days of cultivation. Control in each greenhouse is done by a pump actuator, incandescent bulbs and TL lamps. The result showed that temperature, nutrients and light affect on the growth of mustard. By single factor analysis, we found that maximum leaf area was produced at a temperature of 35 °C that was 565 cm-, nutrition 5 mS/cm that was 639.27 cm- and 17000 lux light that was 697.42 cm-. In short, the best growth rate was obtained at a temperature of 35 °C, nutrition of 5 mS/cm, and 17000 lux of light yield 1068.82 cm- of leaf area.ABSTRAKTanaman sayuran harus dibudidayakan dengan optimal agar diperoleh hasil yang maksimal. Di wilayah tropis seperti di Indonesia, pertumbuhan tanaman sayuran dipengaruhi oleh beberapa faktor iklim seperti kelembaban, suhu, nutrisi dan cahaya. Untuk memperoleh kondisi yang optimal dan terkendali selama periode pertumbuhan, tanaman sawi dibudidayakan secara hidroponik di dalam greenhouse. Penelitian ini dilakukan untuk mengidentifikasi pola pertumbuhan tanaman sawi (Brassica rappa var. parachinensis L.) yang dibudidayakan secara hidroponik di dalam greenhouse yang dilengkapi dengan kendali suhu, nutrisi dan cahaya. Tujuan penelitian adalah menentukan kombinasi faktor terbaik yang memberikan pertumbuhan paling optimal. Penelitian dilakukan dengan memberikan tiga perlakuan dengan tiga variasi yaitu suhu (32 °C, 35 °C, dan 38 °C), nutrisi (2 mS/cm, 5 mS/cm, dan 8 mS/cm), dan cahaya (7000 lux, 12000 lux, dan 17000 lux) sehingga terdapat 27 ruang budidaya atau greenhouse dengan iklim mikro yang berbeda. Tingkat pertumbuhan ditentukan berdasarkan luas daun dan diukur selama 48 hari budidaya. Kendali di dalam masing- masing greenhouse dilakukan oleh aktuator pompa, lampu pijar dan lampu TL (Flourescent Lamp). Hasil penelitian menunjukkan suhu, nutrisi dan cahaya berpengaruh pada pertumbuhan tanaman sawi. Dari hasil analisis faktor tunggal, luas daun maksimum dihasilkan pada suhu 35 °C yaitu 565 cm-, nutrisi 5 mS/cm yaitu 639,27 cm- dan cahaya 17000 lux yaitu 697,42 cm-. Secara kombinasi, tingkat pertumbuhan terbaik diperoleh pada perlakuan suhu 35 °C, nutrisi 5 mS/cm, dan cahaya 17000 lux dengan hasil luas daun mencapai 1068,82 cm-.
