Abstract
Prancak 95 tobacco has the potential to be developed in Indonesia because it has a distinctive aroma and a nicotine content of 2.13%. The quality of this tobacco raw material must be improved and started from the use of quality seeds through in vitro culture techniques. However, several things that must be considered are the acclimatization stages. One of the efforts to increase the growth of seedlings during the acclimation can be done by providing natural plant growth regulators (PGR) from extracts of organic materials such as coconut water, young corn, sprouts, and banana weevil that has been fermented in advance using EM-4 bioactivators . Based on this, the purpose of this study was to determine the optimal concentration of natural growth regulators in the acclimatization of Prancak -95 tobacco. This study uses a non factorial randomized block design with four treatments concentrated solution of natural growth regulators, which include: Control (no treatment), 10; 25; and 50 ml/L. The observed variables included the number of leaves, leaf area, plant height, and root length. Data analysis using ANOVA Test and continued with DMRT Test at 95% confidence level to find out the best treatment. Based on the results of research that has been carried out for 60 days of observation, it can be concluded that the application of natural PGR is able to spur the growth of seedlings during the acclimatization period. Spraying application at a concentration of 10 ml / L can increase the number of leaves, leaf area, number of roots and height of Prancak 95 tobacco seedlings.

Abstract
Coccidiosis is an intestinal parasitic disease caused by Eimeria. The investation of Eimieria can negatively alter poultry health and reduce the productivity of poultry. Decreasing of broiler production can cause economic loss to the farmer and further to the domestic economic. This paper aimed to estimate the economic loss due to coccidiosis in broiler chicken in Central Java Province. The calculation was made based on two parameters: epidemiologic parameter and economic parameter. The data for calculation was based on previous research data and current data. The estimation was calculated using two approaches: direct and indirect method. The direct loss related to the production system cost and extra cost due to coccidiosis cases while indirect loss related to the economic loss in Central Java that could be affected by coccidiosis. The result showed that the direct loss estimation was Rp 3,371,408,383,426,- and indirect loss was Rp 141,430,086,- with a total estimation of economic loss in Central Java due to coccisiosis was Rp 3,371,549,813,512,-. This estimation indicates the importance of coccidiosis control program in poultry industry.

Abstract
Climate change is one of the very serious threats to the agricultural sector. In climate change, season shifts occur, which are marked by the shorter rainy season but with large rainfall, causing cropping patterns to shift. Damage to crops occurs because of the high intensity of the rains impact on floods and landslides. Then, fluctuations in temperature and humidity that are increasing can stimulate the growth and development of plant-disturbing organisms. With this explanation climate change can be detrimental to farmers and the agricultural sector, shrinking and decreasing agricultural output which affects the decline in farmers incomes (Festiani, 2011). Climate change causes the cropping system and planting time in the agricultural sector in Indonesia to change. Unstable changes can cause large losses, especially in the agricultural sector. Then further research is needed to prove the impact of losses experienced due to climate change and other factors. The potential of adaptation actions must be determined for both agriculture and government. The purpose of this research; firstly analyzing the impact of climate change on the production of food and vegetable commodities in Jember Regency and secondly analyzing farmers perceptions of climate change. The targeted research output is the results of the research can be discussed at the 2nd International Conference on Food and Agriculture (ICoFA) of the State Polytechnic of Jember, and the Level of Technology Readiness (TKT) is 4.

Abstract
The low production of kopyor coconuts is caused by kopyor-producing coconut plants that only rely on kopyor-bearing coconut trees that have heterozygot genetic constitution (Kk) and are grown from normal phenotypic coconut seeds. Kopyor fruit cannot be grown naturally. One alternative to get true to type kopyor seeds is by embryo culture. Development of reliable clone propagation such as somatic embryogenesis will quickly provide embryos for kopyor. From one kopyor em-bryo that is produced will get many somatic embryos which can then become kopyor coconut seeds. The aim of this research is getting an effective method to produce true to type kopyor seeds and knowing the influence of 2,4-D with or withaout TDZ in inducing callus to produce somatic embryos. This research was carried out in the Lampung State Polytechnic laboratory using a factorial. Factor 1 is 2,4-D concentration 0, 2,5, 5, 7.5, and 10 mg/l with or without the addition of 0.5 mg/l. Further data analysis using the 5% LSD test. The parameters observed in this study were: 1) Percentage of explants callus 2) Callus diameter, 3) Callus weight. The results showed that Increasing concentrations of 2,4-D and 7.5 mg/l can increase the percentage of embryogenic callus, callus diameter, and weighing callus. The addition of TDZ concentration of 0.5 to the medium 2,4-D resulted in a decrease in the percentage of embryogenic callus, callus diameter is narrower and lower weight on embryonic callus kopyor coconut. The concentration of 2,4-D best to induce callus on embryo kopyor is 7.5 mg/l.

Abstract
Citrus plants have a high growth response. Therefore, regular fertilization is needed to serve the high growth response. Periodic fertilization is fertilizing which is carried out throughout the year at different intervals according to the needs of the orange plant. One thing that is important in the cultivation of citrus plants is recognizing the need for fertilizers in accordance with the stages of growth of citrus plants. Citrus farmers in Padang Rejo, Jember, East Java, Indonesia have been cultivating oranges for a long time but they still rely on conventional fertilization, which is to wait for rain on the grounds that if accompanied by rainwater, fertilizer will quickly absorb. However, if you wait for the rain to fall then if the time of fertilization has arrived but it does not rain, fertilization will be delayed so that the time of fertilization is not appropriate. Therefore, this paper proposes fertilizer irrigation mobile control for regulating fertilization and watering so that the use of fertilizer and water can be regulated and can be more efficient. So farmers can save on production costs, especially in the purchase of fertilizer and labor costs in watering supervision.

Abstract
Improving production system quality, especially in the efficiency of coal combustion, is a must to optimize the electric energy production of a power plant. To maintain customer trust, towards an international standard distribution process, it needs innovation in combustion monitoring. Overheating conditions frequently occur and could break the camera due to limited information on combustion temperatures received by the user. From these problems, this study aims to design a classification system for monitoring the combustion process in the boiler or furnace. Combustion area captured by the Adafruit AMG-8833 IR camera and continued with the extraction and segmentation of thermography analysis and neural network (NN). This study utilizes the features of temperature conversion in each image segment in the form of HSV (Hue, Saturation, Value). Hue parameters (H) and value (V) parameters are used in the classification process for its large degree of red to green differences with a significant range at each temperature. Those parameters are the input of the Artificial Neural Network along with the average & overheating temperature as the classification target. The average error of this system is 0.08559% for the image classification with training data of 64x45 inputs, 16 neurons, and the best performance at 10th repetition.

Abstract
Honey is a sweet liquid produced by bees that is sourced from nectar or liquid from high contained-carbohydrate plants (sucrose, fructose, and glucose). The high carbohydrate content makes it not allowed to be consumed by Diabetes Mellitus (DM) patients. This research aimed to obtain one of the biological values of honey which is Glycemic Index (GI). The result of this research is expected to be reference for the amount of honey that is allowed in one-time consumption especially for people with DM. The type of honey used in this research are from West Kalimantan, namely Tikung and Kelulut. Tikung honey is obtained from a nest called tikung which made from rambesu wood. This honey is widely available in Kapuas Hulu Regency. Kelulut honey is from Trigona sp. cultivation, and widely cultivate in Mempawah Regency. This research is conducted at the laboratory of Agricultural Product Technology (THP) of Agriculture Faculty, Tanjungpura University in collaboration with the Sungai Raya Community as medical personnel in GI measurement. The measurement was taken by in vivo method using 12 healthy respondents. The result shows that glycemic index for tikung honey is 35 (low) and kelulut is 39 (low). Recommendation for maximum honey consumption in one-time based on glycemic load values (low category) is 20g or one tablespoon (for kelulut honey) and 40g or two tablespoon (for tikung honey). This research is expected to be one of the references in honey consumption for both healthy people and DM patients.

Abstract
The need for food and healthy food is increasing now with the development of technology about food processing, especially foods with mushroom types. Oyster mushroom is one type of mushroom that is safe for consumption, because oyster mushroom is one kind of complementary food besides rice which has high nutritional value. Due to having a considerable economic value resulting in a lot of oyster mushroom cultivation which is a type of small business that starts from breeding, production, and processing of oyster mushrooms. Oyster mushrooms can grow in the area around the house, oyster mushroom cultivation takes into account several factors including air humidity, air temperature, and lighting regulation, this type of fungus should not be exposed to direct sunlight. In order to maximize yield, we need a kumbung. making the ideal kumbung namely mushroom kumbung which is always awake to the humidity of the air. While the media used is wood powder media mixed with katul with a composition of 15%, 2% lime, and 5% corn powder. Then the mixture is mixed with water with a composition of 60% and stirred, allowed to stand and check the degree of acidity. Then cooled put into polybags plastic and put in a barrel for cooking process (Steam) for 7 hours to sterilize the media. As for the humidity temperature is maintained between 23-280C. The problems faced by oyster mushroom farmers in Jember City are the regulation of air temperature and humidity that are erratic, when the hot air is very dry humidity, and during the rainy season the humidity is very wet so that it interferes with the mushroom production process. So we need a mechanism that is able to deal with these problems by implementing a mushroom kumbung humidity control system automatically by using a DHT11 sensor connected to Bluetooth HC-06. The function of the DHT11 sensor has been adjusted to the temperature of oyster mushroom humidity. And the second solution is to help control the production and marketing processes by utilizing an integrated management information system.

Abstract
In 2018 the number of active Twitter social media users in Indonesia reached 22.8 million people and 4.1 billion tweets in 2016. Tweets or comments delivered can be used as a reference to determine and consider the business processes that will be carried out. However, the number of comments submitted is very large so that it has difficulty in analyzing the comment data. Besides the comment data on Twitter is an unstructured type of data so that if processing uses a relational database engine the results obtained are not optimal. To deal with these problems, a big data approach is needed in data extraction combined with the comment data processing model. This study uses a combination of big data in data processing and lexicon based to analyze customer comments. Data processing using big data especially with the NoSQL approach is very effective and efficient in conducting searches on unstructured data, this is because the search for big data is based on meta text rather than cardinality between data. While the lexicon based method is a method that depends on the completeness of the dictionary used. The purpose of this study is to analyze comments and share whether they have positive, negative, or neutral sentiments so that they can be used as parameters in decision making in an organization.

Wafer feed form is an efficient form of feed in terms of storage and sheep consumption efficiency because it is not easily scattered when consume. Special techniques are needed to get the optimal product in terms of time and row materials habbatussauda. Eather known as row material, molasses known as the binder for wafers. Viscosity and sugar content of molasses are important factors for the success of wafers forming. The aim of this study is optimize the process of habbatussauda Wafers forming approach with molasses viscosity to the optimal manufacturing time and good quality physical wafers. Wafers process with 105 ºC temperature, wafer forming process in 5 minutes, 10 minutes and 15 minutes, and the viscosity level of molasses is 125% viscosity, 140% viscosity and 150% viscosity. This study used 4 replications per treatment. The experimental design that was carried out was a completely randomized design (CRD) with two factors. The treatments of this study were T1V1 = 5 minutes + 125% , T1V2 = 5 minutes + 140%, T1V3 = 5 minutes + 150%, T2V1 = 10 minutes + 125%, T2V2 = 10 minutes + 140%, T2V3 = 10 minutes + 150%, T3V1 = 15 minutes + 125%, T3V2 = 15 minutes + 140%, T3V3 = 15 minutes + 150%. The parameters were the physical properties of the wafer, machine efficiency and production costs. The results showed that the optimal time to make wafers is 10-15 minutes with a viscosity level of molasses is 140% -150%.

Abstract
Coffee is an important agricultural product which can be used as a feed source for Bali cattle. Consumer preference of organic coffee production need of organic fertilizer product, one of which is obtained from cattle manure that can produce circle of integration system production within cofee and livestock. The aim of this study was to study coffee production by providing compost and liquid fertilizer with various combinations. The method was used completely randomized design (CRD) consist of 3 treatment with 10 replications. C1: Coffee trees get RB 10 kg / tree / year compost combination + 4 liters of liquid fertilizer / tree / year; C2: Tree coffee gets a combination of local microorganism (M1) and compost 10 kg / tree / year + 4 liters of liquid fertilizer /tree /year; C3: Coffee trees get a combination of local microorganism (M2) and compost 10 kg / tree / year + 4 liters of liquid fertilizer / tree / year. Data shows the highest coffee production in C2 and the highest production of agricultural waste in C3. In conclusion the use of local mocroorganism M1 with a combination of liquid fertilizer produces the best coffee production.

Abstract
The global population is projected to grow from around 7.3 billion (in 2017) to nearly 9.8 billion in 2050. In low-income countries, the population can double to 1.4 billion. Therefore, a 50 percent increase in food and other agricultural production will be needed from 2012 to the middle of the century. This increase has implications for agriculture and the food system to adapt significantly to becoming more productive and diversifying while overcoming climate change and unpredictable natural disasters. Therefore, the development of integrated agricultural technology has become one of the main research focuses on Indonesia. With integrated agricultural technology, agricultural productivity can also be increased even in limited land. Based on this, in this study a wireless mobile-robot manipulator control system was developed which is designed to support a smart-greenhouse system using Raspberry Pi. Mobile-robot is equipped with 4 DOF manipulator arms which can be used to carry out several treatments on plants. This research stage begins with the design and planning of a system on a mobile-robot manipulator. Furthermore, modeling and system integration is performed so that the mobile-robot manipulator can be controlled wirelessly based on motion recording using sensors. In the final stage, the robot manipulator performance testing is carried out which has been implemented in an online mobile-robot manipulator control system.

Abstract
Based on the results of monitoring data conducted by the Regional Environmental Management Agency (BPLHD) on 13 rivers that crossed the Jakarta area in 2010 showed that both river water and groundwater have high organic and inorganic pollutants. To cope with pollution, the environmental service periodically in the local city or regency government takes river water sampling at the waste disposal location to examine its water content. The location point for industrial waste disposal is not always easy to reach. Under certain conditions, officers must ride an assembled boat or walk down the river to access the location. Besides taking a long time, human safety factors are also a consideration. Based on these problems, in this study, a wireless sensor network was developed in an Unmanned Aerial Vehicle (UAV / drone) using 912 MHz radiofrequency. UAV in this study is equipped with various sensors to determine water quality, namely: PH, temperature/turbidity, Dissolved Oxygen (DO), and carbon dioxide. All sensors are integrated and monitored wirelessly using Universal Asynchronous Receiver Transmitter (UART) on the ground station. The telemetry system is designed to be able to send and receive data up to a distance of 1 KM in real-time. With a UAV created, monitoring of water quality can be done efficiently and more safely.

Abstract
Soybean is one of important crops in Indonesia because of its role as a source of vegetable protein and it is used as an industrial raw material. Nonetheless, national soybean production is low and cannot keep up with the need. In 2018 alone national production was around 980 thousand tons, whereas the national need for soybeans is around 3 million tons / year. Hence, large amount of import is required to meet national needs every year. This study aims to assemble new high yielding soybean varieties, which have high yield (≥3 ton/ha), early maturity (harvest age ≤76 days), large seed size (>15 g) and have moderate resistance to major soybean disease, the leaf rust, caused by pathogen Phakopsora pachyrhizi. In the previous research, soybean genotypes which fit to the criteria above have been obtained, namely ‘Polije-4- and ‘Polije-5-. However, these genotypes have a major drawback which is the small size of the seed (around 13 g/100 seeds). This drawback can be repaired by using the recurrent backcross method with ‘Ryokko- edamame soybean as the donor parent, which has a distinctly large seed size around 35 g/100 seeds. In the current research, this backcross method between ‘Polije-4- and ‘Ryokko-, as well as ‘Polije-5- and ‘Ryokko- was conducted and resulted in the increase of yield (>20 g/plant) and seed size (>15 g/100 seeds), but still maintaining the early harvest age (≤ 76 days).
