Tree diameter and circumference measurements are important metrics that should be monitored periodically which can used to determine rates of plant growth, timber production (wood), rubber tapping time, estimate the nutrient content soil in agroforestry especially for Albizia sp. trees. In this study, we evaluated use optical sensors, including a smartphone camera, were analyzed by an image processing technology tree homogeneous forests forest plantations, through real-time measurement...

People with disabilities such as hand amputations have limited motor activity. Several robotic prosthetic arms were developed to help them. The challenge arises when the robot's control source comes from user's wishes extracted brain signals via electroencephalography (EEG) signals. This research develops a raspberry-based embedded system device that is connected EEG electrodes and functions an artificial intelligence internet of things (AIoT) so it can be controlled in real-time. deep...

The water availability in soil strongly influences crop growth by sustaining photosynthesis, respiration, and the maintenance of plant temperature. will decrease due to evapotranspiration (ETc) which is influenced reference (ETo) coefficient (Kc). During shortage, Kc evaporation (Ke) basal (Kcb) can be calculated using Blue Red Vegetation Index (BRVI). purpose this study was apply evaluate a new method estimating ETo, Ke, Kcb at research site Deep Neural Network (DNN) with minimum...

Peanuts are the second largest legume crop in Indonesia, both cultivated on farms and wild. In 2019-2023, Indonesia experienced a decline peanut production due to declining harvesting area. addition, this is also poor quality of seeds cultivation process. This study aims observe performance Multi Seed Smart Dryer (MSSD) machine for seeding. research was conducted by observing changes moisture content, drying rate, temperature, germination test results using machine. The showed that left side...

Managing water resources in urban areas is relatively expensive due to the costs of electricity and distribution from wells companies. Therefore, resource management for agricultural purposes needs be made efficient, such as through smart irrigation technologies, one which drip system that engages soil moisture sensors Internet Things (IoT) control amount distributed water. This study aims apply evaluate performance a based on IoT agriculture. The results showed uniformity was identified at...

Transpirasi merupakan suatu proses pelepasan air yang disertai dengan nutrisi mineral dari akar tanaman ke pucuk daun melalui fotosentesis. tinggi akan menyebabkan kekurangan terutama di sekitar perakaran. Dengan demikian, transpirasi ini dapat dijadikan pertimbangan untuk menyatakan status ketersediaan pada tanaman. Tujuan penelitian adalah rancang bangun alat lysimeter berbasis IoT mengukur evapotraspirasi aktual lapangan akurasi sangat baik. Hasil menunjukkan bahwa berfungsi Begitu pula...

The availability of green feedstock for sheep is difficult to find during a dry season. To resolve this problem, seed seedlings such as sorghum and corn are known fodder needed. In order maintain seedling productivity, planting carried out in chamber control temperature, humidity, light regulators. objective study was design growth providing feed. 4×3×3 m (l×w×h) which equipped with tray rack, evaporative cooler, humidifier, exhaust fan, LED strip. A controller unit employed temperature...

A soil water retention curve determination method is developed based on the use of gipsblock and capacitance sensors. The objective research was to provide a simple quick in characterization laboratory resistance Undisturbed sample collected using stainless steel ring sampler 8cm diameter 6cm height. Digital sensors connected personal computer detected periodically tension volumetric content sample. To test reliability data, measurement pressure plate apparatus also conducted. Result...

Indonesia has rainy and dry seasons sequentially from April to October March. In the season, water availability in soil gradually decreases, especially June October, when peak of drought occurs, causing many agricultural lands be left uncultivated. However, a small portion land can still planted for crops such as maize groundnut. limited causes crop growth disrupted because amount absorbed by roots is less than evapotranspiration water. Therefore, an accurate estimation technique needed make...

Wet coffee processing methods will produce wastewater containing organic matter. The high content of matter can be utilized as biogas through the anaerobic process. Anaerobic digesters construction affect removal process pollution and quantity. purpose this study is to determine effect digester between conventional digester, CSTR UASB producing from wastewater.  worked without temperature control system control, a with system. Biomass volume was about 5 L 35 days incubation time....

ABSTRACT The demand was increase each year, but supplies with productions are not belance. This is due by narrowing of agricultural land, verticulture a planting system solution that save land. Vertical cultivation needs to be treated, such as watering keep the optimal soil moisture. wrong will make green mustard maximal and even die. Therefore, this research purpose design an automatic can help s treat control proper . In research, components have been tried before applied moisture...

Abstract Engineering properties and proximate composition of milled rice was determined for different organic varieties, i.e. Ciherang (CH), IR-64 (IR), Sintanur (ST), Pandanwangi (PW), Merah Bali (MB), Coklat Berlian (CB), A2 (MA) Hitam Melik (HM). The engineering parameters included the length (L), width (W), L/W ratio, 1000 kernels weight, bulk density (ρb), angle repose (φ), thermal conductivity (k), volumetric specific heat (Cp), diffusivity (α), colour attributes (L*, a*, b*)....

Bioethanol from seaweed is the ethanol produced anaerobic fermentation of with assistance microorganisms. A distillation process required to separate a mixture - fermented bioproducts. The aims this research are develop distiller equipped control system temperature, evaluate output flow rate and content bioethanol (Euchemia cottonii). desired electric was developed in five main components, i.e., system, heater, distilling tube, condenser, centrifugal pump. starter Saccharomyces cerevisiae...
