Characterization of Several Rice (Oryza sativa L.) Varieties as Germplasm
Characterization of Rice plant (Oryza sativa L.) is required to obtain its potential or to eliminate unwanted characters for variety improvement. This research was conducted from September 2018 to April 2019. Non-factorial randomized block design (RBD) was used, with five varieties, namely ‘Landak’ (V1), ‘Inpari 24’ (V2), ‘Sintanur’ (V3), ‘Sidenuk’ (V4) and ‘Ciherang’ (V5). The characters observed were plant height, number of productive tillers, panicle length, flag leaf length, flowering age, harvesting age, number of grain, number of pithy grains, and yield potential. The data were analyzed using ANOVA and Tukey’s HSD test at 5%. The result showed that Ciherang belonged to the first group (≤ 20 tillers). Sidenuk, Sintanur, Inpari 24 belonged to the second group (21-30 tillers), and ‘Landak’ fell under the third group (> 36 tillers). For harvesting age, ‘Ciherang’ and ‘Sintanur’ were in the first group (≤120 days), ‘Sidenuk’ and ‘Inpari 24’ were in the second group (121-140 days), and ‘Landak’ come under the third group (> 140 days). For 1000 grain weight, three varieties resulted lower than their plant description: ‘Landak’ (20.26 g), ‘Ciherang’ (25.30 g), and ‘Sintanur’ (26.48 g), while ‘Inpari 24’ and ‘Sidenuk’ exceeded their plant description with 26.89 g and 26.06 g, respectively.

The Success Rate of Red Onion (Allium ascalonicum L.) Crosses in the Lowlands Area of Jember
Shallots (Allium ascalonicum L.) are vegetable plants that use as spices and cannot be subtituted. The existing shallot varieties are generally not yet able to adapt to climate change or the altitude of the planted area and are still susceptible to important diseases. Therefore it is necessary to make efforts to obtain superior red onions that are adaptive to climate change and tolerant of important diseases. Red onion crossing is one way to expand genetic diversity, and combine the desired characters so that new populations are obtained as selection material in the assembly program for new superior varieties of shallots. Crosses in this study use local varieties of East Java. Bauji variety is one of the local shallot varieties in East Java which is adaptive in lowland areas, can be planted in the rainy season, and tolerant of diseases. Tajuk variety is also a local East Java variety with the advantage of being able to adapt to the dry season and to withstand the rainy season. The aim of this study was to determine the success rate of crossing two shallot varieties in order to produce an adaptive lowland variety of shallot and tolerant of important shallot diseases. The research was conducted in the Antirogo experimental garden at an altitude of 89 asl from August to November 2020. The study used a non-factorial randomized block design with three replications.

A Review of Morphometric Measurements Techniques on Animals Using Digital Image Processing
The existence of livestock, especially beef cattle in Indonesia, has enormous potential. In 2018, the population of beef cattle in Indonesia reached 16,432,945 heads. This population continues to increase in 2019 to 17,118,650 individuals. The increase in livestock productivity can be assessed from the dimensions of the body of the livestock by measuring directly using measuring instruments. This technique is called morphometrics. Morphometrics is a quantitative analysis technique (body dimensions) that includes shape and size. Morphometric data is an important parameter used to study livestock anatomy, productivity, growth rate, and performance quality of livestock. Manual measurements can provide several obstacles, including causing livestock to be stressed more easily, measurements become less accurate because cattle move too much and can even pose a risk of livestock aggressiveness that causes people to be injured by livestock attacks. This review article aims to summarize the literature related to morphometric techniques in animals in terms of the measurement approach used and the objects measured. Writing review articles are done by summarizing and analyze the morphometric measurement process approach technique. The articles studied were obtained by searching in international and national journals at Springer, ScienceDirect, IEEE, etc. The search was carried out with the keywords "Morphometrics", "Morphometrics", "Zoometric", and "Digital Image Analysis". The conclusion drawn from the review is that there are still many things that can be developed in this morphometric measurement technique. The key to the success of developing this morphometric technique method is that the more effective and efficient the measurement technique is, the better the results will be obtained. The final result expected in the future is to be able to create a morphometric approach technique that can be used in all fields and animals. Able to produce accurate and efficient morphometric measurements.

The position of cattle production in agricultural systems: A balance between food security and emission
The growth of the global population leads to an increase in demand for human edible food and cattle production plays an important role to realize this aim. Cattle or ruminants are capable to transfer fibre rich materials into human-edible products, such as meat and milk. This capability allows the exploitation of grassland, which is 50% of the land available for livestock, and the reuse of a large scale of by-products for the production of food. The use of non-human edible materials may make ruminants net producers of human-edible proteins. The disadvantages of this capability are the emission of methane, contribution to global warming, and the low milk N efficiency, leading to N emission to the environment contributing to water eutrophication, soil acidification, and global warming. Research work showed that the possibilities to reduce both types of emissions are relatively limited. The inclusion of more high-quality protein and starch into the diet reduces these emissions but this change also has a negative effect on the balance between the input of non-human edible material and the output of human-edible products. Balancing between both aspects is done by focusing on the ratio of emission units per animal product. This ratio should be minimized which can also be achieved by improvement of digestion of typical feed ingredients for ruminants, such as forage and fibre-rich by-products, leading to high animal production. Research work should focus on further improvement of the digestion of forages by technological, chemical, and biological treatments. The implementation of these improvements in practice, however, is a great challenge because it affects local agricultural systems and may lead to an increase in the price of animal products.

Exogenous enzyme increased feed intake but not growth and feed efficiency of sheep fed edamame wastes
Feed management strategies, for example using cheap agricultural by product to reduce feed cost, are commonly used in improvement of livestock farming. This research aimed to access efficacy of commercial exogenous enzyme (consisting of mixture lignolytic and cellulolytic) formulated with edamame waste on feed intake, growth, and feed efficiency of sheep. Nine local sheep were assigned using completely randomized design, treated with 3 levels of exogenous enzyme i.e. 0, 1.4, and 2.8 g/kg of total mixed ration formulated using edamame waste. The sheep were reared in individual cage and given treatment in 3 replications. Feeding and drinking were ad libitum and after two weeks feed intake (FI), average daily gain (ADG) and feed conversion ratio (FCR) were calculated. FI was significantly affected by the treatment and FI significantly increased in line with the treatment levels. However exogenous enzyme did not affect ADG and FCR
Determination of the Shortest Path in Web-Based Food Distribution
Food insecurity can be seen in terms of production, consumption, and distribution. The aspect of food insecurity is the ability to produce unbalanced with the fulfillment of needs. Production capability is not seen from the availability side, because availability can be met from the inter-regional supply. The consumption aspect is the inability to buy food because there is no purchasing power or the poor. The availability of food that does not meet the needs of the community resulting in food insecurity. Then the way to handle food insecurity in the region of Bondowoso is by distributing food that requires the shortest path to overcome the many areas that must be assisted given. Determination of the shortest path is a problem to find a path between two nodes with a minimum number of weights. The shortest path can be applied in the form of web-based application programs.
Portable Device for Monitoring System in Network Culture Laboratory based on IoT
Tissue culture is one of the technological developments in the field of agricultural production. This technique is one way of vegetative nurseries to produce ready-to-plant seedlings. The benefits of plant propagation by tissue culture include reproducing pantogen-free plants in large numbers and in a relatively short time. However, in plant propagation by tissue culture it is necessary to pay attention to the factors that affect its success, for example environmental conditions. Environmental condition factors consist of irradiation intensity, temperature and humidity. The intensity of lighting affects the photomophogenesis process of the explants, while the temperature affects the formation of plant organs and the unstable humidity can make the explants and plantlets grow abnormally. In the Tissue Culture which is carried out at the Laboratory of the Department of Agricultural Production, the State Polytechnic of Jember, also often finds culture failure or it is called kontam (mushroom culture / rotten culture / dead culture) due to the influence of an uncontrolled environment. Manual monitoring activities require more effort and time, and the results obtained are not entirely effective. Based on these problems, this study designed a web system that can monitor temperature, humidity, and light intensity as well as remote control of tissue culture rack lighting based on Microcontrollers and Computer Networks. This system utilizes trending technology, namely the Internet of Things (IoT) and cloud computing. The internet of things allows the results of sensor readings to the temperature, humidity and light intensity levels of the tissue culture room to be accessed by the website. In addition, it also allows the website to adjust the brightness of the lighting according to the needs of the plants. In internet of things communication in this study, the compilers used the MQTT (Message Queuing Telemetry Transport) protocol which has the advantage of being able to run on small bandwidthIntroduction.
Teleoperation System for v-Based Sterilization Robot
In December 2019, an outbreak of pneumonia of an unknown etiology emerged in Wuhan, China. A new coronavirus was identified as the cause, which has named 2019-nCoV by the World Health Organization (WHO). January 25, 2020, a total of 1975 cases have been confirmed nationwide with another 2684 cases suspected of being caused by 2019-nCoV / Covid-19. The case in Indonesia was first discovered on March 1, 2020. Based on a study on emerging cases, WHO equated prevention/crisis in the number of sufferers with Middle-East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). WHO confirms that human-to-human virus transmission can occur through droplets, contact, and fomites (the source of infection from inanimate objects). Fomites can be various objects that are touched in daily activities, such as door handles, train handles, chairs, tables, etc. So this research aims to present a solution by using robots for sterilization based on ultraviolet lamps. The robot is designed with a differential drive system and is connected to a computer via a telemetry device. An FPV camera is mounted on the front of the robot to aid operator vision for remote control. The output shows that the room sterilization process can be done remotely without the need for physical contact.

Implementation of the Web Scraping as Extract-Transform-Load (ETL) Module in the Data Warehouse Simulator
Data and information are the main assets in an organization. Especially when the data is very fast, it causes the demand for information to also increase. This phenomenon must be anticipated by the organization, because by paying attention to proper data growth it can increase the organization's profits. However, it takes a different architecture from conventional databases to store this kind of data. This storage architecture is called the Data Warehouse. One of the important Data Warehouse components is the Extract Transform Load (ETL) section. The purpose of ETL is to collect, filter, process and combine relevant data from various sources for storage into a data warehouse. In this paper, we propose a simple ETL model that uses web scraping technique for data retrieval. Web scraping are techniques that have been used to collect data from web sites. Its reliability in data collection, as well as its accuracy in sorting data makes it the right model for the ETL process. However, there are still some adjustments that must be made so that the desired data can be obtained. Among other things, the accuracy in sorting HTML elements and knowledge of finding the exact location of the desired data.
Differential-Drive Wheeled Robot Controller using Pulse-Width modulation in disinfectant sprayer robot
This paper describes dc motor control in disinfectant spraying robots using Pulse Width Modulation (PWM) applied to Koesnadi hospital in Bondowoso, East Java as a tool to help sterilize hospital building hallways during the COVID-19 pandemic. Differential drive wheel with caster wheel combination. The robot has a size of L x W x H: 40 cm x 40 cm x 120 cm moves at a set speed to get even spraying results, but that speed becomes unstable due to the linearly changing load of the disinfectant tube. Using PWM is expected to produce different robot speeds according to the load conditions carried by the robot. The Arduino Nano microcontroller as the main controller is used to manage pwm signal cycles as a reference for robot speed when performing disinfectant spraying tasks. The application of PWM to the disinfectant atomizer robot is explained by calculating the estimated time and speed with the observation of the reduction of load conditions on the robot.
Development of Goods Carrier Robots and Interaction of COVID-19 Patients with Medical Personnel at Politeknik Negeri Jember
Covid-19 virus is the first type of deadly virus found in wuhan city, China. Based on worldometer data that entered until August 25, 2020, in Indonesia, 157,859 people were positively infected with the Covid-19 virus. The increasing number of infected patients is at high risk to nurses and doctors because one of the causes of the infection is by direct contact with patients who are declared positive there is a corona virus. CNN Indonesia on August 25, 2020 recorded as many as 90 medical personnel killed from exposure to the Covid-19 virus. To reduce the risk of coronavirus spreading in nurses or doctors when carrying out the task of treating patients in hospitals or health facilities, Politeknik Negeri Jember designed the manufacture of robots that can bring medical needs or needs of patients to the treatment room. this aims to reduce direct contact between patients and medical personnel. Remote control based on keyboard with radio telemetry is expected to prevent physical contact between medical personnel and patients. So the chances of exposure to the Covid-19 virus are less. The use of an interface in the form of streaming video calls, allows patients to communicate directly with a nurse or doctor (telehealth).

Application of Digital Image Processing to Predict the Diameter of Chrysanthemum Flowers Ready to Harvest
Since 1940, chrysanthemum was developed commercially. Potentially, the cut chrysanthemum commodity still has problems in its development. Chrysanthemum flower production scheduling is needed to increase the quantity, quality and continuity of chrysanthemum production according to market demand. This happens because usually managers or entrepreneurs only harvest flowers en masse without seeing some flowers that should not be suitable for harvesting are also cut off. Therefore, it is detrimental to the manager itself and reduces the quality of the chrysanthemum flower products that are sold. The solution to the existing problem is that there is a need to observe flowers by applying precise agricultural technology according to the times to ensure the bloom time. By knowing this phase, the flower harvest period can be predicted correctly so that the fulfillment of market demand can be met appropriately. Observations in this study use digital image processing with the threshold method, which is then used as a basis for predicting the diameter of chrysanthemum flowers ready for harvest, hopefully this will help farmers or chrysanthemum managers to optimize their harvest. The results showed that the data image observation as a whole experienced the percentage of missing data or errors with possible causal factors due to the density of storage traffic, the effect of lighting, humidity and air temperature. In addition, the use of "image processing" to find the diameter of chrysanthemum flowers ready for harvest has succeeded in approaching the actual condition, although it has not been tested in other varieties.
