Published: December 2022

Abstract
Coffee is one of the most common and favorite beverages that many people have been consuming around the world. A smart coffee roaster uses a smart sensor and controller to operate the roaster and to get the best consistency and also accuracy of the resulting roasted coffee. The current paper discusses the electricity, design, and Artificial Intelligence (AI) needed to make the best version of a smart coffee roaster. The electronic system consists of a sensor, controller, and actuator. Sound and temperature sensors are the ones that are used within the device; meanwhile, the most commonly used controller is a microcontroller. Actuators are the driving motors of the roaster drum. Ergonomic, aesthetic, and user comfort are the primary keys needed to make a good design. The AI application detects the ripeness of the coffee seeds and the “crack” sound detection. Based on the comparison of previous studies that have been done before, readers are expected to identify the required needs of specifications within a smart coffee roaster.
Innovative bolted-steel box for seismic-resistant dry-precast concrete beam-column connection
Authors: Kurniawan Prasetya Donny , Tavio  
Published: December 2022

Abstract
Currently, many buildings are constructed with precast concrete methods. However, they still use the cast in-situ method, especially for the beam and column connection system where there are some obstacles in the casting process and the possibility of installing the reinforcement bars on site not following the design. Hence, there is potential for structural failure in that part of the connection. To reduce the connection constraints, it is proposed that the method of connecting precast concrete with an innovative connection system that is simple, lightweight, fast in the manufacturing process, can be constructed quickly and effectively on-site, and easily meets the specifications of connection quality. This proposed type of connection is a dry joint type that only uses bolts for the connection system with steel box components. This study will prove that the dry joint system can receive the moment and shear load due to earthquakes still in the elastic phase, not experiencing plasticity. The concept of connection planning does not change the concept of the Special Moment Frame System which applies the concept of Strong Column Weak Beam and Plastic Hinges. The connection is ensured in strong conditions, there is no yielding and damage at the time of a large earthquake, so the failure is not in the connection but occurs in the precast concrete block element that is at the end of the beam outside the planned connection in flexural failure with ductile behavior, not shear failure.

Abstract
Sapodilla fruit (Manilkara zapota) is a climacteric fruit having a short shelf life. To extend shelf life, cold temperature storage is often used. During storage, one of the parameters that could change is malic acid. Malic acid can be measured non-destructively using visible-near infrared (Vis-NIR) spectroscopy. However, measurement using VisNIR spectroscopy has limitations, one of which is the sensitivity of the instrument towards temperature. The temperature of the fruit influences VisNIR spectral data, therefore prediction of malic acid using VisNIR is challenging. This study was conducted to study fruit temperature effect on the malic acid measurement of sapodilla fruit using VisNIR spectroscopy. Partial least square regression (PLSR) combined with spectral preprocess (Savitzky-Golay smoothing, normalization, Savitzky-Golay 1st & 2nd derivatives, standard normal variate (SNV), detrending, and multiple scattering correction (MSC) was used to build calibration model. Fruits were stored in three storage temperature i.e. 8°C, 13°C, and 29°C. Spectra of fruit were taken directly after stored in cold condition and after immersed in a water bath at 30°C to obtain normal temperature. Calibration models were built using cold temperature spectra at 8°C and 13°C and normal temperature spectra at 8°C, 13°C, and 29°C.
Determination of calibration coefficient (R²c) of fruits measured in cold condition after stored at 8°C and 13°C were 0.89 and 0.87 obtained using MSC spectra. R²c of fruits measured after submersed in a water-bath after stored at 8°C and 13°C were 0.88 and 0.87 obtained using detrending and MSC spectra. Moreover, R²c of fruit stored in room temperature of 29°C was 0.92 obtained using mean normalization spectra. In general, PLSR models for determination malic acid of sapodilla were not significantly different between spectra of fruits which were cold and were heated to normal temperature. However, the PLSR model was the highest for fruits stored in room temperature (29°C). The results showed the potency of VisNIR spectroscopy for malic acid determination of sapodilla. Moreover, the result also showed that storage temperature and fruit temperature affected PLSR models developed using VisNIR spectroscopy.

Abstract
Arabica and Robusta coffee beans have physical differences in general. In the process of roasting coffee beans with different physical forms, it is possible that there will be differences in the roasting temperature and water content of the beans after the roasting process. Arabica and Robusta coffee beans have physical differences in general. In the process of roasting coffee beans with different physical forms, it is possible that there will be differences in the roasting temperature and water content of the beans after the roasting process. In brewing coffee, it can also be affected by the roasting process. There are several factors that need to be considered in the roasting coffea bean namely early moisture of coffea beans, temperature in the roaster and the time it takes for the coffee beans to ripen as desired. The use of heat energy to get a specific aroma and taste in coffee beans is very necessary. The objective of the research is to determine how the criteria of the roast of Arabica coffea beans and Robusta coffee beans using cylindrical roaster rotates with electrical energy as its heat source. The results obtained at the treatment temperature of 205°C using a rotating cylinder tube coffee roaster using an electric heat source takes 78 minutes to reach coffee maturity with a dark roast level of maturity. Analysis of the color of coffee beans after roasting, it was found that Arabica coffee and Robusta coffee were more dominant, showing on the color track-60 with the Agtron Color Classification System scale, where the initial moisture content of dry robusta beans is 12.50% reduced to 3.66% after roasting, while the initial moisture content of arabica beans is 12.36% reduced to 3.54%.
The effect of adding electrolyte solution to the cream demulsification technique on the purification of palm oil-based MDAG

Abstract
Glycerolysis is the simplest, least expensive, and most prevalent technique for producing mono-diacylglycerol (MDAG). MDAG, a product derived from palm oil, is crucial to the fat-based food sector. Chemical glycerolysis generally leaves crude MDAG with glycerol residues that exceed the European Union’s maximum (up to 7.5%); thus, it must be purified. Cream demulsification is one of the conventional ways of purification for separating glycerol residues from MDAG. This study investigates the impacts of adding electrolytes (calcium chloride, ammonium bicarbonate, magnesium sulfate, and sodium sulfite) and the effects of electrolyte concentration (2.5%, 5%, 7.5%, and 10% w/v) on the concentration of glycerol, monoglycerol, diglycerol, and triglyceride. Electrolytes have a role in transforming the MDAG emulsion system from a water-in-oil (w/o) system to an oil-in-water (o/w) system, causing the emulsion to break down and form cream. Glycerol and water create a polar phase (skim), whereas MDAG form a non-polar phase (cream). The analysis showed that the highest yield was obtained by adding 5% sodium sulfite (SS) electrolyte, which was 44.51±0.60%. Increasing the electrolyte concentration from 2.5% to 5% resulted in a larger yield, but a further increase of up to 10% did not improve the yield. The glycerol content also de creased from 13.36±0.82% to 1.8±0.32% with the addition of 5% SS electrolyte. This result is in line with the fact that the amount of MAG and DAG increased after the creaming demulsification with 5% SS electrolyte (41.68±1.23% and 25.75±0.26%, respectively).

Published: December 2022

Abstract
Antibiotic usage in chickens can help to prevent disease and increase their growth rate. However, many farmers ignore the doses and the withdrawal time of antibiotics usage for chickens so that it can cause antibiotic residue in chicken meat. This antibiotic residue can cause health problems, so it is necessary to take action to reduce or find other alternatives for antibiotic usage in chickens. Therefore, our research objective was to summarize the records of tetracycline residue in broiler chickens. In addition, this research also identifies the effect of Lactobacillus usage as an antibiotic replacement. This research was a systematic review. The systematic review intended to synthesize in detail the information about natural ingredients for antibiotic substitutes and their effect on chicken’s growth from Google scholar, Science Direct, and Pub Med with the keywords “Tetracycline effect,” “Probiotics antibiotic,” “Lactobacillus antibiotics,” “Chicken antibiotics,” “Tetracycline residue” and “Chicken growth.” The results obtained from this systematic literature review were that the residual levels found in chicken samples from Indonesia and Egypt ranged from 0.7 to 61.05 mg/kg. In addition, the addition of Lactobacillus had a positive effect on the weight of chickens, namely the addition of 23.3 to 1421.67 g. This study concluded that the residual levels of tetracycline in chickens exceed the safe consumption limits set by the Standard Nasional Indonesia (SNI). The usage of Lactobacillus was common as feed additives.

Abstract
Environmental stress is a global threat to provide the world’s food. Drought and salinity are the main threats to agricultural land productivity. This is a challenge in implementing SDGs 2030 as well as an opportunity if we are able to use germplasm to overcome various environmental stresses. Research on 2 varieties of rice Inpari 42 agritan as a comparison variety and varieties Sigupai which is a local variety of Aceh originating from Abdya. This study used a 2x3x6 split plot design with 108 experimental units and 324 experimental pots. There is an interaction between varieties when salinity occurs and salinity level on the growth of rice plants in the vegetative phase and electrical conductivity in soil and water which shows different responses between the Inpari 42 Agritan variety and the Sigupai varieties. On the electrical conductivity of the Sigupai. variety, it was better able to reduce Ec at different levels of salinity and time of occurs in the vegetative phase. Meanwhile, Inpari 42 Agritan is more capable of increasing growth under conditions of increased salinity in the vegetative phase. The local variety Sigupai, the rate of growth reduction is also relatively low compared to that without salinity. This is an opportunity to deal with drought and salinity that can occur anytime and anywhere due to drought, water management and improper fertilization that can occur anywhere. It is a challenge to overcome drought and lowering salinity with the use of local varieties and appropriate agronomic practices.

Published: December 2022

Abstract
Adsorption becomes one of the most promising separation methods for contaminants removal because it is easy to apply and offers efficient and environmental-friendly process. Adsorption by powder adsorbent has the advantages of high capacity and fast kinetics to remove contaminants in wastewater due to the large surface area. However, powder adsorbent has the weakness of difficulty to separate the small particle size of adsorbent in batch mode of adsorbent-solution system. Therefore, to solve this disadvantages, there is one way to facilitate the separation of adsorbents by supporting the particles of adsorbent at a polyurethane foam (PUF). The PUF with filled adsorbents allows the adsorbent to interact freely with pollutants and be easily separated from polluted water. Studies show that the integration of adsorbents in the PUF has the potential to absorb various contaminants and it can be separated easily from contaminated water.

Published: December 2022

AbstractThe sediment microbial fuel cell (SMFC) is a new technology that uses exoelectrogenic bacteria and organic compounds to transform chemical energy into electrical energy. The application of SMFC technology is gaining popularity since it can simultaneously reduce contaminants in wastewater and generate electricity. An SMFC performance is mainly governed by the kinetics of the electrodes within the fuel cell, of which the materials that make up the electrodes significantly impact their performance. The objective of the ongoing investigation was to study the performance of three types of electrodes for minimizing pollutants from landfill leachate wastewater while also generating electrical energy. Sediment and leachate samples were taken from the Regional Landfill wastewater treatment facility in Blang Bintang, Aceh Besar, the Province of Aceh. Three transparent acrylic reactors with a length, width, and height of 45 cm, 20 cm, and 12 cm, respectively, were employed in this experiment. The electrode materials utilized in this study were zinc (Zn), copper (Cu), and iron (Fe), with each electrode having a surface area of 124 cm2. Temperature, pH, voltage, and carbonaceous compound removal measured as COD were used to assess the SMFC performance. The study results showed that the temperature and pH of the three reactors have a similar trend, and the values are not much different at 24.36±0.25°C and 9±0.03, respectively. The reactor installed with Cu electrode produced the maximum electrical voltage of 470 mV, whereas those with Fe and Zn had the highest voltages of 107 mV and 23 mV, respectively. The percentage of COD removal for reactors equipped with Zn, Cu, and Fe electrodes was 40.70%, 41.09%, and 41.23%, respectively. Although the COD removal by each reactor of different electrode materials did not show a significant difference, the reactor with Cu electrode gave better performance when viewed from the electrical voltage.
Classification of tomato (Lycoersicon Esculentum Miil) ripeness levels based on HSV color using digital image processing

Published: December 2022

Abstract
Tomato is a fruit that undergoes a rapid ripening process. Classification of tomatoes based on the level of ripeness is very important during the distribution process of tomatoes in various regions. In general, farmers classify the ripeness level of tomatoes based on fruit color, because this is easy to do. Generally, the classification of the ripeness level of tomatoes is done manually by looking directly with the eyes and based on the color of the fruit. The problem is, manually identifying the level of ripeness of tomatoes based on color still has many shortcomings and the results are less than optimal. This is because humans have many limitations such as differences in perceptions by farmers, fatigue, lack of focus, relatively long time required and produce a variety of products due to human visual limitations and differences in perceptions about the quality of tomatoes. One alternative technology that can be used to reduce this problem is to use digital image processing with color spaces such as hue, saturation, value (HSV). HSV color has a tendency to detect color with a degree of dominance to get accurate object recognition results. Using digital image processing techniques, information is obtained that can be processed by a computer and the results are more precise, fast and automatic. Based on the results of research using image processing with HSV color space can identify the maturity level of tomatoes at three levels of ripeness, unripe, half-ripe and ripe.

Abstract
Pocut Meurah Intan Grand Forest Park (Tahura) is a form of nature conservation area which is overgrown by various types of plants that are widely used by bird species such as forage trees and nesting trees. Bird species from the Bucerotidae family are one of the fauna that take advantage of the presence of various types of plants in the area. When the existence of plants that function as feeding trees or nesting trees is threatened, the impact will be experienced by various bird species due to habitat changes such as a shortage of life-supporting plants. One of the factors that influence the use of trees in their habitat by birds is the density and canopy cover. The purpose of this study was to analyze the percentage of canopy cover for forage trees and bird nesting trees in the Bucerotidae family in Tahura Pocut Meurah Intan. Descriptive method is the method chosen in this study. The research location stations were determined using purposive sampling. To determine the canopy cover of forage trees and nesting trees, Canopycapture ver.1.0.2 software was used with the Hemispherical Photography method. Hemispherical Photography is a method by calculating the area of the canopy cover using a camera from under the tree canopy. This method produces more accurate data because the area captured by the camera is more specific so that it describes the actual tree canopy cover.
