Due to the development of Internet of Things (IoT) and extensive use of Wireless Sensor Networks (WSN) in precision agriculture, we take potato crops as a study domain for sensors and their behavior on their deployment in a particular area. We study how application responsiveness is determined by performance metrics in wireless communications. We also describe how data collected by the sensors aids in finding solutions to the cropfis domain problems through data aggregation over time. The aim of this work is to analyze traffic behavior of a grid-topology wireless sensor network, chosen based on the distance between rows and potato plants within a hectare, by analyzing the performance of a service request from an IoT application.

WSN analysis in grid topology for potato crops for IoT

Mandailing Natal district as the second largest district in North Sumatra Province has great potential for horticultural development. This study aimed to determine the sustainability level of horticultural development in Mandailing Natal district through 5 dimensions, namely ecological, economic, social, technological and institutional. The RAPFISH-MDS analysis method was used to measure the index and sustainability status. The results showed that the criteria for the sustainability of horticultural development in Mandailing Natal district was quite sustainable (52.61) with the sustainability index value of the ecological, institutional, social, economic and technological dimensions, respectively, 58.06; 56.86; 53.76; 51.99; and 51.08. Sensitive attributes supporting sustainability are erosion rate for the ecological dimension, post harvest management for the economic dimension, extension intensity for the social dimension, land management technology for the technological dimension, and conflicts between farmer groups for the institutional dimension. The realization of horticultural development can be through the development of government programs and extensions that change farmers' perceptions of the environment and the application of eco friendly technologies in their farming.

Sustainability Study of Horticultural Development in Mandailing Natal District With RAPFISH-MDS Analysis


Abstract.Yassi A, Demmallino EB, Sultani HR. 2023. Tropical climate change and its impact on horticultural plants in Enrekang District, South Sulawesi, Indonesia. Biodiversitas 24: 3073-3079. Global, regional, and local changes in climate are phenomenologically different and have distinct impacts on the horticultural and agricultural sectors. Therefore, this research aims to examine tropical climate change in South Sulawesi, Indonesia and analyze its impact on horticultural crops. Apost-positivistic interpretation framework of the case study tradition was used, while the location was determined by purposive sampling followed by comprehensive data collection. Data were analyzed using integrated techniques, and validity tests were carried outto assess thecredibility and reliability. The results indicated a local climate change marked by a differencein the pattern of distribution and intensity of extreme rainfall between 2015 and 2018. This was due toan increase in air temperature, which on average reached ±0.03731°C from the lowest of 22.50°C in 2011 to the highest of 23.12°C in 2020. In other words, it can be stated that the air temperature had increased by ±0.63°C in the last decade. The impact on various types of horticultural crops was marked by a decrease in the production of several kinds of Chinese cabbage,carrots, and green beans in 2015 as well asa very drastic reductionin potato crop production in 2018, while cabbage plants experienced a peak in production in 2018. Some types of horticultural crops such as shallots, cabbage and red chili began to stabilize and even increased their production in the aftermath of climate changeduring said period.

The silt pit is a method of soil management that functions to accommodate and absorb surface runoff. The research aimed to determine the silt pit effectiveness for erosion reduction and nutrient loss. The research is located at 576 above sea level (asl) in Sukamantri village, Taman Sari district, Bogor Regency. The experiment used a randomized block design with three replications and a slope group. The treatments were R0 (without silt pit); R1 (silt pit); R2 (silt pit + mulch); R3 (silt pit + mulch + biopore tube), R4 (silt pit + mulch + biopore tube + vertical crop tube). The highest runoff-decreasing occurred on R4 treatment, which pressed down 29.38% runoff. The highest value of erosion-decreasing occurred on R2 as 68.74% and followed by effectiveness in reducing the loss of 71% Organic C, 76% available P, and 67% total N. The dry seeds peanut yield was around 0.54 - 0.86 Mg ha-1, dried pods was 0.96 - 1.33 Mg ha-1, and dried biomass was 5.16 - 6.23 Mg ha-1 and not significantly different between all treatments. This study recommends that farmers apply silt pit innovation technology with a combination of mulch, biopore, and mature green media because the incremental B/C ratio was 1.175. It is a good economic indicator for farmers.
