Some properties of paper sludge were analyzed, including water content, organic material content, pH value, fiber content, ash content,C,H,O,N,S and metal content in dried sludge. The results showed that water content was high, organic material content was high, pH value was in a neutral level, metal elements were varied. Besides, calorific value was detected in a thermal power plant.Disposal of residue wastes from pulp and paper mills is a paramount issue facing the world today. Paper sludge is the solid waste from papermaking industry. The sludge treatment and disposal process will bring about environmental pollution. Therefore,much attentions should be paid to disposal of paper sludge. It is expected that this paper can provide deep insights into the disposal of paper sludge.

Kabupaten Tanah Laut has many sugar palm trees especially in the area of the ​​Guntung Besar and daerah Ranggang. But the manufacture of palm water in the area is only made into sugar print / brown sugar because the manufacture is more practical. If brown sugar is kept at room temperature, then brown sugar is easily melted. Therefore further processing is needed to maintain the quality of brown sugar. The purpose of this research is to make brown sugar with drying temperature variation. This research use ekspremental method with 4 treatment that is drying temperature 100oC, 75 oC, 50 oC, and control (without temperature drying). The test used in this research is pH test, water content test, ash content test and organoleptic test. The result shows that the pH value of sugar water used ranges from 6 to 7, the water content is 2,97% with the value of SNI maximal 3% and the ash content is 1, 98% with the value of SNI maximal 2, 0% at treatment A1 already fulfill SNI, Organoleptic test on flavor, aroma, texture and color obtained best result that is at treatment P1

Catfish is one of the leading commodities in aquaculture in Indonesia. Catfish derivative products are currently very much developed, one of them was smoked catfish. The characteristics of smoked fish are influenced by several factors, including the type of firewood used. This study aims to examine the chemical and physical characteristics of smoked catfish with different burners. The smoking method used is heat fumigation. The parameters observed were proximate, pH value, phenol content, formaldehyde content, characteristics of color, texture and aroma. The results obtained, protein content, water content, ash content and fat content using laban wood are higher than rambutan wood 60.6%:58.8%; 6.65%:5.54%; 7.97%:7.29%; 20.4%;14.6% repectively. The phenol value of smoked fish using laban wood is higher than that of rambutan wood 0.2401ppm:0.2204ppm respectively. Formaldehyde levels in both types of wood are negative. The characteristics of the two smoked fish are the same in texture, aroma, pH and temperature parameters were solid texture, typical aroma of smoked fish, pH value 6.7 with a temperature of 80-100oC respectively. But the color of smoked fish by burning laban wood is bright brown while the rambutan wood is shiny brown.

The extraction time was 60 minutes with 5 treatment levels of HCl concentration ie K1 = 2%, K2 = 3%, K3 = 4%, K4 = 5% and K5 = 6%. Each treatment was repeated three times. Gelatin analysis consists of water content, ash content, protein content, pH value, viscosity, and gel strength. The highest water content was 15,76% at 2% HCl concentration, the highest ash content was 44,40% at 2% HCl concentration, and the highest protein content was 23,23% at 3% HCl concentration. The highest pH value was 4.14 produced by gelatin at 2% HCl concentration, viscosity was 5,13 cP and gel strength of 252,43, the best bloom was produced by gelatin at 6% concentration level. The conclusion of this research is the best quality of gelatin is obtained by using chicken bones and the use of chloride acid for 24 hours and 6% HCl concentration level.

Abstract Counterfeit electronics constitute a fast-growing threat to global supply chains as well as national security. With rapid globalization, the supply chain is growing more and more complex with components coming from a diverse set of suppliers. Counterfeiters are taking advantage of this complexity and replacing original parts with fake ones. Moreover, counterfeit integrated circuits (ICs) may contain circuit modifications that cause security breaches. Out of all types of counterfeit ICs, recycled and remarked ICs are the most common. Over the past few years, a plethora of counterfeit IC detection methods have been created; however, most of these methods are manual and require highly-skilled subject matter experts (SME). In this paper, an automated bent and corroded pin detection methodology using image processing is proposed to identify recycled ICs. Here, depth map of images acquired using an optical microscope are used to detect bent pins, and segmented side view pin images are used to detect corroded pins.

The olive oil industry represents an important productive sector in the Mediterranean basin countries. Olive stone is an essential by-product generated in the olive oil extraction industries and it represents roughly 10% by weight of the olive fruit. The seeds of pickled olives are also a significant waste product. In the present study, we have investigated the possibility of the use of differential scanning calorimetry for the thermal characterization of seeds from green and black pickled olives from Croatia. The differential scanning calorimeter (DSC) with a normal pressure cell equipped with a cooling system was used to determine the thermal properties of seeds from olives. The following analyses were also performed: the determination of calorific values in a pressure bomb calorimeter, the determination of initial water content, the determination of changes of water content during drying at the temperatures of 30 °C, 50 °C and 80 °C, the determination of a percentage content of seeds mass to the mass of the whole olives, and the determination of ash content. Seeds from olives are characterized by very good parameters as a biomass. The analyzed olive seeds were characterized by low water content, low ash content, and a relatively high caloric value.

We report on the die bonding processes and how the surface roughness and metallization schemes affect the processes of die bonding in 4H-SiC device fabrication using a soldering test and die shear test (DST) with differently prepared 4H-SiC samples. The first set of samples (FZ#1 and FZ#2) was capped with sequentially evaporated Ti and Au on an annealed Ni layer. The second set of samples (FZ#3 and FZ#4) and the third set of samples (FZ#5 and FZ#6) were prepared by 4μm-thick Au electroplating on an annealed Ni layer and an un-annealed Ni layer, respectively. The quality of the soldering, such as the solder coverage, void, and adhesion, was characterized by optical microscope, X-ray microprobe, and DST. We found that the samples (FZ#4 and FZ#6) deposited by Au electroplating on C-face (bottom-side) 4H-SiC provided a satisfactory result for the tests of solder coverage, void, and DST and also realized the cleaning process prior to the electroplating and soldering was the most crucial in the die packaging processes of vertical structure devices. The void fraction measured by X-ray microprobe for the samples, FZ#4 and FZ#6 was 2.2% (average for 5 samples) and 0.8% (average for 3 samples), respectively.
