Judul: Kajian Pembuatan Teh Celup Dengan Daun Pegagan (Centella Asiatica L. Urban)
Abstrak: Trend of back to nature has been widely developed in the world. One of the products from crop gotu kola is an herbal tea. Herbal tea contains powerful herbs for health. Packaging form of bags has been made to increase the added value of gotu kola tea. Tea bags are packaged processed food products in the packaging bag made from filterpaper that can be presented instantly and quickly. Gotu kola plant contains many chemical substances that useful to human’s health. Gotu kola can be clean the toxins blood from the body,improve digestive disorders and delay wrinkles. In addition it can helpimprove stamina, memory, mentally, and also help balancingthe energy levels, decrease symptoms of stress and depression. The active agent of this plant can also increase IQ, mental ability, such as mentally weak disorder in children. Making gotu kola tea bags in this study consisted of two types, namely sweet type and non sweet type, stevia is used to be sweetener. Through organoleptic test, panelist were asked to express they response to several tests of taste, aroma and color of a tea bag steeping of gotu kola. The results of analytical of chemical praresearch for raw materials of herbal tea ie gotu leaves, green tea leaves, citrus leaves and stevia leaves showed that the water content range ie 5,88-7,43 % w / w (SNI: max 8 % w / w) ash content, ie 4,65 - 5,76 % w / w (SNI: max 8 % w / w); and fiber content, ie 10,23 - 12,74 % w / w (SNI: max 16 % w / w). But all of the samples do not follow the standard of ISO, in terms of water soluble ash content, ie 35,63-41,22 % w / w (SNI min 45 % w / w). Results of quality analysis from all the selected samples showed that all of the samples have been met with SNI, which are not torn after soaking for about 15 minutes both cold water and hot water. Based on the results of statistical calculations can be obtained that the panelists preferred formulation for non sweet type is to the G formula, the composition are from 20% grams of gotu kola ; 60% of green tea; and 20% of citrus leaves. Where as for sweet type is preferred to the D formula, the composition are from 42,86% of gotu kola; 28,57% of green tea; 14,285% of citrus leaves; and 14,285% of stevia.

Judul: Formulasi Teh Celup Campuran Teh Hijau (Camellia Sinensis)-Murbei (Morus Alba)–Stevia (Stevia Rebaudiana) serta Pengaruhnya Terhadap Aktivitas Antioksidan
Abstrak: Tea is one of the fuctional beverage which has been researched and developed for health benefits. Mixing of Green Tea (Camellia sinensis)-Mulberry (Morus alba)-Stevia (Stevia rebaudiana) into a tea bag has a potential as functional beverage due to phenolics compound which is known can act as antioxidant. The main objective of this research was to study the antioxidant effects of the mixing of green tea-mulberry-stevia tea bag formulation. Factor used in this study was the level of mulberry tea in green tea-mulberry-stevia mixing tea bag which were 13.33% (FA), 23.33% (FB), 33.33% (FC), 43.3% (FD), and 53.33% (FE). The data results showed that the total phenolic content of the five formulas were in the range of 528 to 1216 mg/100 g and the antioxidant were in the range of 563 to 670 mg/100g AEAC (Ascorbic Equivalent Antioxidant Capacity). The highest total phenol content and highest antioxidant was found in formula FA which contain 13.33% of mulberry tea. Analysis also showed that there is a positive correlation (p<0.05, r=0.902) between total phenolic content and antioxidant in green tea-mulberry-stevia mixing tea

Judul: Heisenberg Uncertainty of Double SlitSystem Based on Budiyono-Rohrlich Quantum Statistics Model
Abstrak: Interpretasi kuantum dikembangkan untuk memaknai secara fisis dengan jelas bagaimana suatu dinamika pada sistem mikroskopis yang dijelaskan dengan teori-teori kuantum, seperti interpretasi Copenhagen yang mendeskripsikan sistem kuantum sebagai suatu keadaan yang dideskripsikan dengan fungsi gelombang yang berisikan bagaimana peluang keadaan suatu sistem. Interpretasi kuantum juga bisa dibawa dari suatu sistem klasik seperti pada model statistika-kuantum Budiyono-Rohrlich yang menjelaskan bagaimana dinamika kuantum berhubungan dengan sistem klasik dengan penerapan statistika pada model Hamiltonian sistem. Fungsi distribusi dapat mendeskripsikan bagaimana suatu sistem terdistribusi pada suatu ruang pada pandangan klasik namun untuk sistem kuantum fungsi distribusi adalah peluang dari sistem tersebut. Sistem klasik dan kuantum juga dipisahkan berdasarkan pada ketidakpastian Heisenberg tentang suatu pengukuran yang tidak bisa secara sekaligus dilakukan bersamaan. Model statistika-kuantum Budiyono-Rohrlich membawa suatu sistem klasik menjadi sistem kuantum dengan dua aksioma yaitu hukum kekekalan energi rata rata dan konservasi rapat probabilitas. Sistem klasik yang didefinisikan akan diatur dengan menambahkan dua variable matematis berupa ontic extensions dan epistemic restrictions dimana kedua variabel ini yang akan menghubungkan bagaimana sistem klasik bisa diubah menjadi sebuah sistem kuantum. Dua variabel matematis tadi membuat sebuah sistem bisa diperlihatkan ketidakpastiannya lewat perhitungan simpangan rata-rata dan hasilnya akan selalu memenuhi ketidakpastian Heisenberg
