Untuk total flavonoid yang terbaik pada perlakuan waktu pelayuan 12 jam dengan suhu pengeringan 70 oC yaitu 27.1697 mg/100g.   Tea is herbal drink that is consumed by many people. The processing of tabah bamboo leaves (Gigantochloa nigrociliata BUSE-KURZ) into tea is an effort to utilize the compounds in it that are able to give a distinctive character to the results of tea products later. This research was conducted with the aim of determining the yield and characteristics of tabah bamboo leaf tea from different treatment time withering and drying temperatures. This research has been carried out from May 2019 to July 2019 in the Post Harvest Laboratory of the Faculty of Agricultural Technology, Udayana University, Biochemical and Nutrition Laboratory, Faculty of Agricultural Technology, Udayana University and the Food Analysis Laboratory, Faculty of Agricultural Technology, Udayana University. This study uses a Completely Randomized Design (RAL) consisting of two factors, the first factor used in the design of this study is the duration of withering and the second factor is the drying temperature. The first factor consists of three levels, namely (P1): 8 hour withering, (P2): 10 hour withering, and (P3): 12 hour withering. The second factor consists of three levels, namely (T1): temperature 50 ° C, (T2): temperature 60 ° C, and (T3): temperature 70 ° C. The parameters observed in the study consisted of chemical analysis including water content, pH, total acid, total phenol, total flavonoids and organoleptic tests consisting of the color of the brewing water, aroma, and taste in the brewed tea leaves. The results showed that the best phenol content was found in the treatment of 12 hours withering time with a drying temperature of 70 oC, 114.5664 mg / 100g. For the best total flavonoids in the treatment time withering time of 12 hours with a drying temperature of 70 oC is 27.1697 mg / 100g.

Penelitian ini bertujuan (1) mengetahui penanganan pascapanen yang dilakukan pasar modern sampai selada dipasarkan; (2) menentukan nilai tambah dengan penanganan pascapanen dihitung dengan profit margin di pasar modern. Penelitian ini dilakukan pada awal bulan September sampai akhir Oktober 2016, metode yang digunakan dalam penelitian ini adalah metode deskriptif dengan pengamatan langsung menggunakan kuisioner untuk mengumpulkan data. Penelitian dilakukan disalah satu pasar modern dan pasar tradisional untuk membandingkan perlakuan penanganan pascapanen terhadap selada. Penanganan pascapanen merupakan salah satu upaya suatu perusahaan untuk memberikan nilai tambah terhadap selada. Pasar modern dengan tingkat penjualan semua jenis selada sebanyak 88,99 kg dapat mengembalikan biaya penanganan pascapanen. Sedangkan pasar tradisional harus menjual selada sebanyak 121,55 kg untuk mengembalikan modal awal. Penanganan pascapanen sangatlah penting untuk mempertahankan umur simpan selada. Selain mempertahankan umur simpan selada, pasar modern memperoleh keuntungan lebih dan mendapat perhatian lebih dari konsumen dibandingkan pasar tradisional. Hasil penelitian ini juga memperoleh profit margin yang berbeda. Profit margin yang diperoleh pasar modern adalah sebesar 129,87% sedangkan profit margin yang diperoleh dari pasar tradisional adalah sebesar 25,3%. Profit margin yang diperoleh pasar modern sebesar 129,87% menunjukkan bahwa rasio penjualan yang tinggi merupakan kemampuan perusahaan menghasilkan laba yang tinggi pada tingkat penjualan tertentu, sebaliknya jika rasionya rendah menandakan penjualan yang terlalu rendah untuk tingkat biaya tertentu, atau biaya yang terlalu tinggi untuk tingkat penjualan tertentu. This study aims to (1) find out postharvest handling conducted by modern markets until the lettuce is marketed; (2) determining the added value with postharvest handling calculated by profit margin in the modern market. This research was conducted in early September until the end of October 2016, the method used in this research is descriptive method with direct observation using questionnaires to collect data. The study was conducted in one modern market and traditional markets to compare postharvest handling treatment of lettuce. Postharvest handling is one of the efforts of a company to provide added value to the lettuce. The modern market with the selling rate of all types of lettuce as much as 88.99 kg can restore the cost of postharvest handling. While the traditional market must sell as much as 121.55 kg lettuce to restore the initial capital. Postharvest handling is very important to maintain shelf life of lettuce. In addition to maintaining shelf life of lettuce, the modern market gains more and gets more attention from consumers than traditional markets. The results of this study also obtained a different profit margin. Profit margin obtained by modern market is 129,87% while profit margin obtained from traditional market is 25,3%. The profit margin obtained by the modern market of 129.87% indicates that a high sales ratio is a company's ability to generate high profits at a certain level of sales, on the contrary if the low ratio signifies sales that are too low for a certain level of cost, or cost too high for the level specific sales.

Rice is a staple food for the people of Indonesia. Even though Indonesia is an agrarian country, Indonesia currently imports rice. In producing rice from rice there are obstacles. One of the main obstacles is post-harvest handling of rice with high yield loss during post-harvest. The amount of post-harvest loss occurs because most farmers still use traditional methods or the handling is not good and right. The purpose of this study was to determine the relationship between the capacity of the grinding machine and the quality of sosoh rice produced by the mill and to know the quality comparison of various types of grinding machine capacity. The research was carried out in the area of ??Wanasari Village, Tabanan-Bali to find out the quality of sosoh rice in the region. Head Rice is broken rice grains, both healthy and defective, which have a size greater than or equal to 6/10 part of the average length size of whole rice grains that can pass through the surface of the indented plate basin with a requirement of 4.2 mm hole size. Rice husk is a protective cover from rice grains which is separated from seeds during the grinding process. In the grinding process, there is rice which remains the husk which is caused by the power / rpm of the grinding machine which is too low because the friction force produced by the engine is not sufficient for the overall release of rice husk

The purpose of this study was to determine the effect of spacing on the growth and yield of spinach plants with hydroponic NFT (Nutrient Film Technique) and to determine the most effective spacing and spinach results of hydroponic NFT plant growth. This study uses a Completely Randomized Design (CRD) consisting of four treatment spacing, namely 5 cm, 10 cm, 15 cm and 20 cm. Each treatment uses the same number of plants as 15 plants in one gutter. The study was conducted for 20 days. The parameters observed were plant height, number of leaves, fresh weight, dry weight, root length, and stem diameter. High parameters and number of leaves are measured every two days, while parameters of fresh weight, dry weight, root length, and stem diameter are measured after harvest on the 20th day. For the final value obtained from the calculation of plant height growth parameters, namely JT5 (27.45), JT10 (32.45), JT15 (33.22), and JT20 (32.94). And for the final value obtained from the calculation of the number  leaf growth parameters, namely JT5 (11.21), JT10 (12.19), JT15 (12.51), and JT20 (12.17). While the final value of crop yield parameters for root lengths is JT5 (28.06), JT10 (30.43), JT15 (31.36), JT20 (30.70). For the stem diameter the average value obtained is JT5 (0.72), JT10 (8.84), JT15 (0.90), JT20 (0.85). For fresh weight of plants, the average values ??obtained are JT5 (182.40), JT10 (208.24), JT15 (215.07), JT20 (210.76). And for dry weight, the average value obtained is JT5 (9.51), JT10 (13.52), JT15 (15.05), JT20 (13.71). It can be concluded that from the results of the ANOVA analysis, the treatment of 15 cm spacing had the best results and the spacing of 5 cm showed the lowest results in each treatment observed.
