Abstract

As the demand for precision agriculture intensifies, the integration of robotics into crop harvesting processes becomes imperative. This study addresses the design and evaluation of a gripper specifically tailored for a robotic arm, aiming to enhance the efficiency of tomato harvesting. The gripper is meticulously crafted, employing a 3 mm plywood material and subjected to rigorous testing at variable angles of 40°, 45°, and 50°. The design process initiates with a meticulous blueprint and laser printing, utilizing 3 mm plywood to create a robust gripper structure.  Experimental trials are conducted to assess the gripper's performance under different angle configurations. The results reveal an exemplary success rate, with a 100% achievement in the successful transfer of tomatoes without incurring any damage. The gripper's adaptability to variable angles proves crucial in maintaining. the integrity of tomatoes during the harvesting process. Furthermore, data analysis encompasses crucial parameters such as gripping time, torque exerted by the gripper, and the percentage of tomatoes successfully transferred Testing results reveal a gripping time of 0.14 seconds, indicating an efficient gripper with the highest torque at a 40° angle. The detailed design and adaptive nature of the gripper hold promise as precision technology for tomato harvesting, contributing to discussions on the integration of robotics in agriculture, particularly in optimizing harvests. Future recommendations include enhancing the gripper's structural materials for increased durability and incorporating pressure sensors to further refine its capabilities

Abstract

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.

Abstract

Yellow pumpkin is rich in vitamin A, carotene, and other essential nutrients, and has good durability. Apart from being a food and vegetable, pumpkin can be processed into semi-finished flour which becomes a processed product. This study aims to examine the effect of sodium tripolyphosphate (STPP) concentration on the physical and chemical properties of modified pumpkin starch (Modified cucurbita moschata starch). This study used an experimental method in the laboratory with a completely randomized design (CRD). The concentrations of STPP used in the treatments were 0.1%, 0.3%, 0.5%, 0.7%, and 0.9% of the weight of pumpkin starch. Each treatment was repeated 3 times, totaling 15 experimental units. Parameters observed included solubility, swelling power, moisture content, and starch content. Data were analyzed using analysis of variance (Anova) with a real level of 5% and Least Significance Different (LSD) further test. The results showed that STPP concentration had no significant effect on solubility and swelling power, but had a significant effect on the moisture content and starch content. The higher the STPP concentration, the higher the water content and the lower the starch content. The 0.9% STPP concentration had the highest moisture content (15.54%) and the 0.3% STPP concentration had the highest starch content (92.63%).  In order to be more complex, further research is carried out to test the parameters of phosphate content, ash content, amylose content, amylopectin content, color, PH, viscosity, anthocyanins, crude fiber, gelatinization, syneresis, antioxidants, polyphenols, reducing sugar, water holding capacity and oil holding capacity.

Abstract

The development of microcontroller and semiconductor technology continues to increase in line with demands for system control and monitoring, including in the context of renewable energy. This control and monitoring process is also applied in biogas production. Conventional biogas plants in the field are not monitored so that communities face various challenges including a lack of organic material (low organic loading rate) and overload (excessive organic loading rate). Overloading slows or stops the anaerobic digestion process and can cause total system damage. Furthermore, another challenge that arises from inadequate or nonexistent monitoring of biogas plants is poor production due to excessive temperature fluctuations or inappropriate temperature ranges for various types of methanogenic bacteria. this research introduces an innovative monitoring system capable of accurately tracking several key parameters, including air temperature and humidity (DHT22), organic material temperature (DS18B20), and biogas pressure (MPX5700DP). This solution is built on the Internet of Things (IoT) concept, utilizing Arduino as the sensor data processor and Wemos D1 Mini as the wifi module connecting the system to the IoT platform, Cayenne. These findings provide valuable insights into the performance of the biogas installation during that specific time period. With the implementation of this monitoring system, it is anticipated that the efficiency and stability of biogas production can be improved through accurate and real-time monitoring of key variables in the biogas production process. Analysis of monitoring data reveals that the highest air temperature generally occurs during the daytime, particularly between 13:00 and 14:00, while the lowest air temperature is recorded in the morning around 05:00 to 06:00 on rainless days. Additionally, organic material temperature exhibits fluctuations, with the lowest point typically occurring between 06:00 and 09:00, and the highest point between 15:00 and 20:00. Biogas pressure reaches its peak on the sixth day, namely on January 10, 2022, at around 13:00, with pressure reaching 3.9 kPa.

Abstract

One of the causes of low productivity in cucumber plants is due to low soil quality due to low organic matter content and high sandy soil mixture. Considering this, it is necessary to try to improve it. So, there is a need for research that examines the addition of organic matter and combines sandy media with paddy soil.This research took place in Pecoro Village, Jember Regency from May 2022 to July 2022. The research method was in the form of a Completely Randomized Design with the first treatment, namely the addition of baglog waste compost and cow manure (K1); baglog waste compost and goat manure (K2); and compost baglog waste and chicken manure (K3). While the second treatment is sandy planting media consisting of: sand 100% (M0); 75% sand + 25% paddy soil (M1); 50% sand + 50% paddy soil (M2); and 25% sand + 75% paddy soil (M3). The observed variables included plant height, total fruit weight, fruit unit weight, fruit length and fruit diameter which were tested by means of variance and Duncan's Multiple Range test.The results showed that the treatment of compost, sandy planting media, and their interactions had a significant effect on the observed variables. The recommendations given based on the results of the analysis for cucumber cultivation are the need to add organic matter such as compost mixed with baglog waste and manure from cow, goat and chicken manure with a ratio of 25% sandy planting medium to 75% paddy soil.

Abstract

Cayenne pepper plants are one of the plants that are susceptible to excess and lack of water during their growth period. Lack of water can cause chili seeds to not grow optimally, so chili plant nurseries need ideal media to be able to provide optimal water. This research aims to determine the growth and duration of the permanent wilting point in the growth of chili plant seeds based on differences in planting media in the form of magot compost, soil containing pumice and paddy soil under conditions without watering. The treatment in this research used three different planting media, namely compost, pumice, and paddy soil media. Providing water to chili plants by watering 3 times a day and without watering. The research method uses experimental methods with observations in the greenhouse and there are three treatments, namely using magot compost, pumice and soil media. The parameters observed included growth in height, number of leaves, and width of the plant leaves as well as the length of time to the permanent wilting point. The data from the research were analyzed using ANOVA with the help of SPSS. The results of the research showed that the compost media had the best growth with a height of 9 cm, the number of leaves was 6 pieces, and leaf width 2.9 cm, while the permanent wilting point duration of the three media used was found in compost media, which experienced the longest permanent wilting point at the age of 10 days. So it can be concluded that the best planting medium is found in maggot compost media with the highest growth and longest wilting point.

Abstract

National soybean production is not enough to meet the national demand for soybeans so there is a need to increase the production of this commodity because it is needed as a raw material for various processed products. The utilisation of dry land as soybean cultivation land is still lacking. This is due to several factors, namely cultivation techniques, and limited fertilisation. So the use of cultivation techniques by applying biocompost fertiliser is one approach to improve soil nutrients and also the use of Trichoderma spp. bacteria helps soybean plants to avoid wilt disease.  This study aims to determine the growth response of several varieties of soybean on dry land by applying biocompost fermented by Trichoderma spp. The method used in this research is an experimental method carried out by manipulating the object of research and the existence of controls. The research was conducted on dry land in Giri Tembesi Village, Gerung Sub-district, West Lombok Regency, the soil type of the experimental site was regusol soil with a pH of 5.7 and organic matter moisture content of 0.77%. The results showed that the application of biocompost to several varieties of soybean has not been able to spur plant growth but in general can adapt to dry land. Differences in soybean varieties resulted in significantly different growth responses in plant height, number of leaves, number of branches, flowering age and weight of 100 soybean seeds. However, there is no significant difference in the application of biocompost on the vegetative and generative growth of soybean in dryland which is thought to be caused by the dose of biocompost given is not optimal. Therefore, further research is needed to obtain the optimal dose of biocompost.

Abstract

Herbal drinks are one of the most popular drinks for consumption because of health benefits. Herbal drinks are drinks that made from plants (dry form) such as flowers, fruits, seeds, stems, rhizomes, leaves and so on. Moringa leaves are plants whose leaf parts are often processed into herbal drinks. The high antioxidant in moringa leaves can improve the function of herbal drinks, but moringa leaves has an unpleasant aroma. Therefore, red ginger is used to improve the sensory and chemical quality of herbal drink. The purpose of this study was to obtain the best proportion of the main ingredients on the chemical quality of herbal drink products. This study used a completely randomized design (CRD), with 7 treatments of material proportions, namely JK0 (Moringa leaf powder 0%: red ginger powder 100%), JK1 (Moringa leaf powder 15%: red ginger powder 85%), JK2 (Moringa leaf powder 35%: 65% red ginger powder), JK3 (50% moringa leaf powder: 50% red ginger powder), JK4 (65% moringa leaf powder: 35% red ginger powder), JK5 (85% moringa leaf powder: 15% red ginger powder) and JK6 (100% moringa leaf powder: 0% red ginger powder). Each treatment was repeated 3 times and 21 experimental units were obtained. Based on the results of the analysis of variance and Tukey's further test (5%), it is known that the proportion of moringa leaf powder and red ginger powder produces a significant effect on chemical quality (water content, pH and antioxidant activity) in herbal drink. The best treatment for the proportion of moringa leaf powder and red ginger powder was produced by JK5 (85% moringa leaf powder: 15% red ginger powder) with chemical quality, like water content of 4.56% (suitable SNI 4324-2014), pH with a value of 5.16 and antioxidant activity with a value of 65.96%.

Abstract

Mangrove plants (Avicennia marina) come from the Avicenniaceae family. The leaves have antioxidant, antiviral and antibacterial activity caused by the content of secondary metabolites in mangrove leaves in the form of flavonoid compounds. Research on the total flavonoid content of 96% ethanol extract and the water, ethyl acetate, and n-hexane fractions of A. marina leaves has never been carried out. The aim of this study was to determine the total flavonoid content in extracts and fractions of A. marina mangrove leaves by UV-Vis spectrophotometry method. Extraction was carried out using 96% ethanol solvent by sonication method, then fractionation was carried out using the liquid-liquid fractionation method. The extracts and fractions obtained for their secondary metabolites were identified by test tube and thin layer chromatography and then the total flavonoid content was determined by the colorimetric method. Mangrove leaf extracts and fractions contain secondary metabolites of flavonoids, phenolics, saponins, steroids, triterpenoids, and alkaloids. The results of thin layer chromatography confirmed the results of the tube test that mangrove leaf extracts and fractions contained flavonoid compounds. Total flavonoid content in 96% ethanol extract, water fraction, ethyl acetate fraction, and n-hexane fraction of A. marina mangrove leaves were 19.37; 3.07; 11.30; and 56.62 mg quercetin equivalent/gram sample. In conclusion, the total flavonoid content of A. marina leaves was high, thus supporting its activity as an antioxidant.
