Abstract

The research is to design the price information system of agriculture products with Android technology basis. The system is useful for the farmers, society or any agribusiness people in getting agriculture product price information. the users are classified according to their accessibility right which are society users that only to access the price information, the users plus group that have the right to provide the price information and the administrator group that have full authority towards the system. The administrator can accept or deny the information provided by the user plus group. The system is developed in accordance with the stages of system/development life cycle (SDLC) through waterfall method. The stages are: analyzing stage to learn the functional and non functional system needs; designing system to design the physical system, logic and interface ; implementing stage that cover the implementing the programming language – Java , and android operating system; assessing stage to assess the system through Black Box testing and; maintaining stage to maintain the system. The assessment result indicates that the system works well; every button designed can function as expected. The test by users also shows that they get the easy access to the information. The users can easily understand the operating manual of the system as it is user frendly and equippped with product pictures visualization. In the future, it is suggested that the system come complete with more agricultural information as horticulture, plantation, fisheries, and livestock.Keywords: Android, Black Box, agriculture product price, informtion system, SDLC

Abstract

The objectives of this study are (1) analyzing the types and utilization of ICT, (2) analyzing business profits and the effect of ICT adoption on MSME revenue performance, and (3) analyzing factors affecting the ICT adoption of processed food MSMEs in Lampung Province. This research was conducted in Lampung Province, covering Bandar Lampung City, Central Lampung Regency, Pringsewu Regency, South Lampung Regency, Metro City, and Pesawaran Regency. Locasi is determined intentionally (purposive), considering that the location has adequate ICT facilities and access. The samples from this research were MSME actors in the production of superior processed foods, especially banana chips, cassava chips, emping melinjo, tempe chips, eyek-eyek, crackers, jackfruit chips, and kelanting based on the KJPU in Lampung Province. This study used a sample of 40 respondents. This research is a survey method. The data used in this study were divided into two, namely primary data and secondary data. The research data were analyzed descriptively qualitatively and quantitatively. The data are tabulated, mathematically analyzed, and statistically analyzed according to the purpose of the study. The results showed that the highest level of ICT use used by processed food MSMEs in Lampung Province, namely mobile phones, reached 95%. The most widely used social media whatsapp reached 77.5%. The most widely used use of the marketplace is the shoppe marketplace, but the use of the marketplace as a marketing medium for processed food MSME products is relatively low, only reaching 30%. Internet usage is quite high, reaching 82.5% and respondents think that the internet has an important role in marketing products, communicating with customers, and finding packaging information and product labels. Adopsi of ICT by processed food MSMEs in Lampung Province is still relatively low. Business revenues for processed food MSME actors were obtained by IDR 4,213,737.50, business profits obtained by IDR 2,448,951.73 in 2021. The level of ICT use has a significant influence on the performance of Processed Food MSMEs.

Abstract

Automatic irrigation has long been used to efficiently irrigate large agricultural areas through drip irrigation systems to minimize water wastage. In greenhouse irrigation, computerized control is essential to improve productivity, as conventional control methods that rely on on-off or proportional control are often inefficient. This research introduces a novel approach to monitor greenhouse environmental conditions and control irrigation duration. The monitoring system architecture consists of sensor nodes and a gateway. The irrigation duration control uses a Fuzzy Logic Controller (FLC) based on the Mamdani method. The FLC is implemented on a NodeMCU ESP8266 board integrated with a DHT22 sensor and a soil moisture sensor. Temperature and soil moisture parameters are used as inputs for the fuzzy logic system in determining the appropriate irrigation duration. The linguistic variables used in the fuzzy membership function include soil moisture (categorized as water, wet, and dry), temperature (categorized as cold, normal, and hot), and watering time (categorized as zero, short, medium, and long). A rule base consisting of nine fuzzy rules was developed based on these membership functions. Experimental results show that the FLC implemented on the NodeMCU ESP8266 has an average accuracy of 99.41% compared to the MATLAB simulation. This shows the fuzzy logic-based system's high accuracy and effectiveness in controlling the duration of greenhouse irrigation. This developed system offers a promising solution to optimize water usage and improve irrigation management in a greenhouse environment.

Abstract

Orchids are one of the Indonesian people's most widely cultivated ornamental plants. Orchids are a family ofplants in the Orchidaceae family that includes more than 700 genera and around 28,000 individual species. In terms ofplant morphology, orchids can be distinguished based on the morphology of flowers, leaves, fruits, stems, and roots.Orchid leaves have their characteristics for each type of orchid, such as long, round, or lanceolate. All orchids have leafveins that are parallel to the leaves. This makes it difficult to identify the type of orchid flower, especially for laypeopl ewho are new to orchid cultivation and do not yet know the characteristics of various kinds of orchids. The individualshapes of orchid leaves can be classified using Random Forest and Histogram of Oriented Gradients (HOG). In thisstudy, three types of orchids that are currently popular with orchid lovers were used, namely Cattleya, Phalaenopsis, andVanda orchids taken from public data. The accuracy of this method in classifying orchid types based on leaf morphologycan be measured using a confusion matrix that measures accuracy, precision, recall, and F1-score. The test results showthat this method successfully achieved an accuracy of 98%, with an average precision, recall, and F1-score of 0.98 each.These findings indicate that the model built can classify orchid species with a high level of accuracy based on leafmorphology.
