При обрушении зерна белого люпина используют технологические схемы, позволяющие получать крупку из ядра. Порядок выполнения операций оказывает существенное влияние на результаты процесса обрушения зерна. Режим дробления не изменяли, что привело к получению недоруша (без изменения влажности партии зерна) в размере 6%. На количество недоруша оказывают влияние интенсивность применения агрохимических средств в технологиях возделывании белого люпина, а также почвенно-климатические условия и влажность зерна во время обрушения. Хорошие результаты показала простейшая схема с измельчением на центробежной дробилке с последующей пневмосепарацией, которая позволяет получать до 70% крупки с повышенным содержанием белка и низким содержанием клетчатки, что важно при производстве комбикорма в птицеводстве и свиноводстве. Одновременно при этом производят мучку с пониженным (около 20%) содержанием белка и повышенным содержанием клетчатки (около 10%), что делает возможным её использование в рационах КРС. Определено, что смена технологических режимов работы оборудования сказывается на качестве обрушения зерна белого люпина, т.к. снижение скорости удара при дроблении (при постоянстве остальных режимов процесса обрушения) приводит к росту доли крупки (снижению относов и мучки), но при этом увеличивается содержание недоруша. Повышение скорости потока воздуха при пневмосепарировании снижает долю крупки, поскольку большая часть её мелкой фракци попадает в относы, а качество крупки возрастает, т.к. в относы попадают крупные частицы оболочек и зародыш. Уменьшения размера сита до #2,1 мм приводит к перераспределению фракций в относах. В оболочках, которые в основном составляют сход с этого сита, могут появиться частицы ядра. После просеивания относов и выделения оболочек, доля которых может составлять до 20%, остаётся мучка. Мучка несмотря на повышенное содержание клетчатки может содержать в мелких фракциях до 30% белка. Hulling is a process of separating the grain from its hulls. Hulling steps significanlty affect the final result. Crusing mode stayed unchanged leading to 6% of unhulled grain (no variation in grain water content). Application of chemicals, environmental conditions and grain moisture content influenced the proportion of unhulled grain obtained. Good results were obtained when using centrifugal crusher. After the chaffing 70% of crushed grain showed high protein and low fiber contents, which was importain for poultry and pigs feeding. At the same time being poor in protein (around 20%) and rich in fiber (around 10%) the produced bran could be used in cattle diet. Variation in the parameters of the processing equipment affected the quality of crushed grain. Reduced crusing speed increased both hulled and unhulled grain fraction, decreasing hull and bran contents. Increasing air flow rate reduced the fraction of crushed grain but improved its quality since most of the grain fine fraction got separated together with large husk and corcle particles. Decreasing sieve size induced the redistribution of separated fractions. Some husks were separated together with grain particles. The hull proportion could reach up to 20% without the bran. Despite the high fiber content, the bran can contain up to 30% of protein.

The physiological quality of seeds of native species is important to produce healthy saplings and therefore guarantee the success of programs to recover disturbed vegetation. This reinforces the necessity for investigating the physiological quality of those seeds. To evaluate the effects of different drying rates on the germination, moisture content and storability of Eugenia involucrata diaspores, mature fruits collected at Mogi Guaçu, SP, Brazil had their epi- and mesocarps removed by washing and were dried at 30, 40 or 50ºC until their water content was reduced from 57% (fresh diaspores) to 13% (final drying), totaling six drying levels. In a second experiment, diaspores had their moisture content reduced from 57% to 49%, at 30ºC, totaling six drying levels (0h, 1h, 2h, 3h, 4h and 5h), and were kept for 180 days in plastic bags under cold storage. The drying rate had no effect on tolerance to desiccation by E. involucrata diaspores; water contents lower than 51% decreased both germinability and storability. Diaspores can be stored for up to 180 days as long as their water content is reduced to 53% and they are kept inside plastic bags under cold storage.

Numbers of Mold and Yeast on White Pepper from BangkaWhite pepper is one of Indonesia's spices that are needed for both public consumption and exports. Post-harvest processing of white pepper by farmers is often done with unclean. Each source of white pepper has different water content and will affect the quality of white pepper. In this study, seven samples (S1, S2, S3, S4, S5, S6, S7) were from Bangka. All samples tested had higher water content than SNI quality standard (13%), but still below the quality standard 2 (18%). Sample S2 has the highest water content compared to other samples. Sample S1 and S2 have high Numbers of Mold and Yeast (AKK) and do not suitable with quality standart of BPOM. Of all samples, S2  had the highest AKK (5,51 x 104 colony / g) and sample S5 had the smallest AKK (8,8 x 102 colony / g). This shows the relationship between water content in white pepper with AKK. White pepper that has a high water content has a high AKK, whereas white pepper that has low moisture content has low AKK.Keywords: white pepper, Numbers of Mold and Yeast, moisture contentABSTRAKLada putih adalah salah satu rempah Indonesia  yang  banyak dibutuhkan baik untuk konsumsi masyarakat ataupun ekspor.

Abstrak. Sebagai produsen kopi Arabica, masyarakat Gayo terkendala pada suhu lokal di Aceh Tengah yang relatif dingin dan teknologi sederhana yang digunakan untuk proses pengeringan kopi. Suhu rata-rata harian adalah 23-29°C. Bahan yang digunakan pada penelitian ini yaitu biji kopi yang diolah dengan metode semi basah sebanyak 9kg. Parameter penelitian meliputi suhu pengeringan, kelembaban relatif, kadar air dan rendemen. Hasil penelitian menunjukkan bahwa suhu pengeringan menggunakan alat pengering Hohenheim jauh lebih tinggi sekitar 10-20°C dari suhu pengeringan secara penjemuran. Proses pengeringan kopi labu sampai bisa digiling membutuhkan waktu selama 12 jam yaitu 8 jam pada hari pertama dan 4 jam pada hari ke-2. Sedangkan proses pengeringan tahap 2 membutuhkan waktu selama 16 jam sampai menghasilkan kopi beras dengan kadar air 9,32%. Kualitas kopi beras yang dihasilkan sudah baik dengan kadar air  yang sudah memenuhi standar SNI, tidak berbau busuk, dan tidak terkontaminasi. Nilai rendemen kopi beras berbasis kopi labu adalah 35%.Study of Drying Semi Washed Gayo Coffee Use Dryer Type Hohenheim Abstrack. As an Arabica coffee producer, the Gayo community is constrained by the relatively cold local temperatures in Central Aceh and the simple technology used for the coffee drying process. The average daily temperature is 23-29 ° C. The material used in this study was coffee beans which were processed by the semi-wet method of 9kg. Research parameters include drying temperature, relative humidity, moisture content and yield. The results showed that the drying temperature using a Hohenheim dryer is much higher around 10-20 ° C than the drying temperature by drying. The process of drying pumpkin coffee until it can be ground needs 12 hours, which is 8 hours on the first day and 4 hours on the second day. While the process of drying stage 2 takes 16 hours to produce rice coffee with a moisture content of 9.32%. The quality of rice coffee produced is good with water content that meets SNI standards, does not smell bad, and is not contaminated. The yield of pumpkin coffee-based rice coffee is 35%.

Biogas is a renewable energy source with many different production pathways and numerous excellent opportunities for use; for example, as vehicle fuel after upgrading (biomethane). Reliable analytical methodologies for assessing the quality of the gas are critical for ensuring that the gas can be used technically and safely. An essential part of any procedure aimed at determining the quality is the sampling and transfer to the laboratory. Sampling bags and sorbent tubes are widely used for collecting biogas. In this study, we have combined these two methods, i.e., sampling in a gas bag before subsequent sampling onto tubes in order to demonstrate that this alternative can help eliminate the disadvantages associated with the two methods whilst combining their advantages; with expected longer storage stability as well as easier sampling and transport. The results of the study show that two parameters need to be taken into account when transferring gas from a bag on to an adsorbent; the water content of the gas and the flow rate used during transfer of the gas on to the adsorbent.
