Abstract
Rice is an important food crop commodity and a priority of the agriculture program in Riau Province. In Siak Regency, the total production of irrigated land rice in 2018 was 21,937.02 t Milled Dry Grain (MDG) with average productivity of 5.47 tons/ha of Harvested Dry Grain (HDG). In general, the productivity of irrigated land rice in Siak Regency is quite high, with varies between locations (4.68-6.60 tons/ha HDG). The purpose of this study was to determine the production of Logawa, Ciherang and Inpari 42 varieties on the application of ICM for irrigated land rice in Siak Regency, Riau Province According to the results of research on irrigated land rice production of new superior varieties (Logawa, Ciherang and Inpari 42) in integrated crop management (ICM) obtained an average production of 8.50 tons/ha HDG. Low productivity of rice is caused by (i) the use of inferior quality varieties, (ii) the use of fertilisers that are not following the recommendations, and (iii) the location-specific technology has not been applied yet. Increasing rice production and productivity can be carried out by using new superior varieties within ICM. The results showed that the application of new superior varieties within ICM resulted in higher HDG production (8.25 - 8.90 tons/ha) compared to non-ICM (6.20 - 6.50 tons/ha). The increase of HDG production are ranging from 2.05 - 2.40 tons/ha (33 - 37%) compared to non-ICM. The application of new superior varieties within ICM increasing profit of Rp 21,963,750 - 24,609,000 (30 - 33%) each planting season/ha. The total costs incurred by ICM farmers for one planting season are Rp. 15,161,250 - Rp. 15,441,000/ha with an income of Rp. 37,125,000 - Rp. 40,050,000/ha/season and RCR value of 2.45-2.59 and BCR of 1, 23 - 2.59.

Abstract
The Caspian Sea, which is known as the largest lake in the world, is located in the northern part of Iran. Caspian Sea Sprat or Clupeidae are pelagic fish and play an important role in the food chain. In Iran, clupeid fish are caught by a conical lift net with artificial light and at night. The color of artificial light used in the conical lift net is white or sunny. In a study conducted from May 2018 to January 2019 in the fishing port of Amirabad, the effect of two types of artificial light (blue and red light) was investigated. For this purpose, two lamps with a color of blue and red with the same Volt and Ampere of white light were used in the depth of 40 – 50 meters. The results show a significant difference in the average length of sprat fish caught in each of the lights used (p <0.05). In blue light, the fish caught had a longer length and a heavier weight, while the fish caught in red light had a shorter length and a lighter weight.

Abstract
This study aims to develop a carrageenan gel strength test method with an emphasis on the carrageenan gel preparation method for measurement. The gel was prepared by comparing the two heating temperatures (80 °C and 90 °C), heating devices (waterbath and hotplate) and measurement (with container and without container). The results showed that there were no difference between cooking temperatures of 80 °C and 90 °C, but heating at 80°C obtained a lower deviasi standard. The use of hotplate and waterbath were not significantly different resulted in gel strength, but the use of hotplate had a slightly larger variation than waterbath. Measuring the strength of the gel that was still in the crystal container and removed from the container were not significantly different, but measurements with the gel condition were still in the container obtained more accurate test results. Based on the results of this study it can be concluded that the carrageenan gel preparation technique by heating at a temperature of 80 °C using a waterbath or hotplate is the best preparation test method. Meanwhile, the gel does not need to be removed from the container before being measured using a texture analyser. The development of this method can be used as a standard gel preparation method for measuring the strength of carrageenan gel.

Abstract
Thermoplastic agar (TPA) was prepared by a melt extrusion process and the effects of water contents on the material properties of these foams were investigated. Bioplastics were produced by mixing agar, glycerol, and water at ratio agar; glycerol: water was 5:3:2; 5:3:3; and 5:3:4 through the melting process at 120 °C and 18 rpm. The addition of water affected the extrusion process more easily, so the pellet could move easily from the extruder, but the moisture content of TPA increased with water addition. Then, TGA analysis showed no difference in decreasing mass in the sample with water addition. Permeability, elongation, contact angle, density, moisture content, and WVTR of bioplastics increased with water addition. The FTIR curves indicated that the interaction between water and agar may form much more hydrogen bonds. The best treatment was bioplastics with agar:glycerol:water=5:3:2, which have characteristics: tensile strength 16.19 MPa, elongation at break 102.56%, moisture content %, contact angle 72.81°, density 1.38 g/ml, moisture content 3.09%, transparency value 0.067, and WVTR 1334.59 g/m2.24 h.

AbstractProbiotics are useful organisms in preventing the spread of disease in aquaculture. Therefore this study aims to evaluate the effect of administeringBacillusNP5 on the growth, survival rate, and histology of catfish withAeromonas hydrophilainfection. To achieve this, catfish (7.75 ± 0.02 g) were reared for 45 days with a density of 20 per tank. Furthermore, the study consisted of 4 treatments and 3 replications, namely K+: 0%BacillusNP5+0.1 mL A.hydrophilainjection, K-: 0% Bacillus NP5 + without A.hydrophilainjection, A: 0.3%BacillusNP5, and B: 0.8%BacillusNP5. The results showed that the addition of probiotics significantly increased the growth and survival rate of catfish (P <0.05) compared to K+. The higher value of specific growth rate was found in treatments A and B (0.22 ± 0.03 and 0.23 ± 0.03% day-1, respectively) and the lowest in K+ (0.14 ± 0.03% day-1). Also, the tissue damage in K+ was higher than in the probiotic treatment. Besides, hyperplasia, congestion, and secondary lamella fusion in the gill tissue were found in the K+, while other treatments were found only in hyperplasia. Melanomacrophages occurred in catfish kidney tissue for all treatments, however, hydropic degeneration was found in the control treatment. The addition of Bacillus NP5 in feed resulted in higher growth, survival, and tissue damage compared to K+. Also, the addition of 0.8% Bacillus NP5 resulted in less catfish tissue damage.

Abstract
Milkfish floss is indigenous food from Banten which is produced by Small and Medium Enterprise (SME). Milkfish floss is potential to be developed due to the high demand from outside Banten areas, but it is very easy to get rancidity, spoilage by the microbes, or existing dust and hair. Therefore, milkfish floss production process still needs to improve the processing method according to the standards to produce a safe and good product. Quality assurance is done by compiling hazard analysis and control point (HACCP) documents. The aim of this study was to identify hazards of raw material and production chain, determine CCPs in every chain, and create HACCP document plan. The research method was conducted by interview, observation, laboratory analysis, and literature review. The compiling of the HACCP document is carried out in several steps including creating a HACCP team, identification of consumers and product descriptions, making processing flow diagrams, identifying hazards, determining critical control points (CCPs), determining the critical limit, monitoring, and correcting action. The hazards that may occur in milkfish floss are residues of heavy metals, pathogenic microbes, thorns, dust, and hair. The CCPs of raw material are fish, lemongrass, lime leaves, shallot, and garlic, while the CCPs of the processing are the acceptance of fish, cleaning, steaming, frying, draining, and packaging.

Published: April 2021

Abstract
Camphor resin has been harvested from the Sumatran camphor tree (Dryobalanops aromatica) since the seventh century on the western coast of Sumatra, Indonesia. High beneficial compounds contained, a-pinene, 1.8-cineole, camphene, limonene, and p-cymene reveal the opportunities for prospective utilization as an anti-viral, expectorant, and immune system booster with a relaxing fragrance. The objective of the study was to determine consumer preferences for new Sumatran camphor essential oil-based products. Forty consumers were asked to provide an assessment of personal care products combination. A conjoint analysis approach was assisted by a computer with SPSS 14.0 program. The influence of five product profiles on consumer preferences including functionality, scent variant, packages, volume, and prices were examined. The results show that higher utility values indicate a greater preference. The highest utility value is indicated by the scent variant, this illustrates the respondent’s preferences for their preferred scent. Moreover, the scents (importance value 52.15) is the most influential on overall preferences. This means that there is a large preference differentiation between product profiles containing most and least desired scents. This is due to the preference for a particular scent is personal and unique which might have affected personal perception, which is closely related to initial recognition for a particular scent as an olfactory memory. The highest consumer’s preference is an inhaler product with floral scent, package roll-on, volume 6 ml, and price IDR50,000. Products with inhalation functions are intended to obtain a relaxing effect, reduce anxiety, and calm the mind, improve the respiratory system and immune system.

Abstract
Additive manufacturing is the most recent and the most revolutionary technology in the production industry. It is an unconventional method of manufacturing. In this manufacturing method, material is added one layer upon another layer to get the required shape and size of object. Most complex objects can be built very easily by this technology. Additive manufacturing has the capability to reduce the supply chain by reducing a number of processing stages of a product. Additive manufacturing technology developed a lot from the day 3D printing technique, introduced as Stereolithography in 1984 by Charles W. Hull. Today we have different types of 3D printing techniques such as polymer resin based printing, wire based printing(FDM) and powder based printing(SLS) and some hybrid Additive manufacturing like High speed sintering. Additive manufacturing has applications spread from Aerospace industry to Toy industry and from Biomedical industry to Construction field. Additive manufacturing leads to “Social manufacturing” which involves customers in all stages of product manufacturing. Most of the large scale industries are investing a large capital in R&D for this 3D printing. Many startups are entering into the market each day. Today bio-compatible kidneys, bones and even hearts are bio printed, multi-storey buildings have already been 3D printed and research works are in progress. Now researchers are stepping towards 4D printing which uses “Intelligent” materials which can be coded. Research work is being done on different Additive manufacturing techniques and different materials and process parameters. This paper is a review of Additive manufacturing and it’s latest trends. The Trends related to printing technique as well as materials.

Abstract
The Vapor Compression Refrigeration System (VCRS) uses a circulating refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Capillary tubes are commonly used as expansion device, serving almost all small refrigeration systems to reduce the pressure and temperature of the refrigerant and to regulate the flow of refrigerant to the evaporator. Objective of this research is to develop an analytical method for computing the length of capillary tube required for a specified reduction in temperature and to determine various thermodynamic and transport properties for refrigerant fluids and mixtures viz. R22, R427A, R407C, R32, R410A, available in REFPROP database and perform a comparative analysis. For achieving this objective, a mathematical model is developed using the integration of MATLAB and REFPROP software programs.

Abstract
Defense organization is one of the most reputed organization where best of the officers and soldiers serve for the safety on one’s country, without complaining about anything and giving their all in to protect us from various threats that could lead to disintegration of the country.
Thus, the main motive to develop this device is to help our defense services to get the best, while they are giving their best for the country. The idea is to develop a device that would counter the recoil of the gun used by the officers and soldiers, to make them more efficient. Keeping in mind that the renewable resources of energy are depleting at a fast pace and pollution is increasing day by day leading to global warming, we have taken air as our resource to produce the desired effect. The device would be developed using aluminium, compact single cylinder air compressor and arduino programming to measure the pressure required for each shot fired from the gun. The principles of Law of conservation of momentum are applied to reduce the recoil of the gun to 80 %, thus helping in better aiming and precision. By installing this device, the demerits that makes AK47 a primitive gun would be subdued and without buying the expensive advanced guns, the arsenal would be upgraded at minimal cost possible.
