A Study of the Secure Decision Method for Obstacle Avoidance

2023-09-18T23:25:06+00:00

This paper proposes a secure decision making method for obstacle avoidance for bicycle robots using camera, lidar and GPS. Using a camera, a waypoint is generated on a path with a lookahead distance and steering angle can be calculated for path planning. At the intersection, the GPS signal can determine whether to turn or not. For obstacle avoidance, lidar detects the obstacle and calculates the repulsive potential, which is used to calculate the steering angle and speed. Integrating these information from sensors, this paper show the result of simulation that control bicycle robot.

Diversity Analysis of Several Indonesian Yam Bean (Pachyrhizus erosus) Accessions

Yam bean (Pachyrhizus erosus) is one of the introduced plants that thrives well in Indonesia. Yam Bean exhibits a considerable range of variability, contingent upon its cultivation region. The objective of this study is to analyze several Indonesian yam bean accessions in order to identify accessions yielding high harvest results and tuber inulin content. This research was conducted in Duku, Kasang, Batang Anai, Padang Pariaman. Observations and analyses were carried out in the Plant Physiology Laboratory, Instrumentation Laboratory, and Biology Laboratory of Andalas University, Padang, from January to December 2022. The experiment was arranged in a Completely Randomized Design, consisting of 11 yam bean genotypes from various yam bean production centers in Indonesia. The research results indicate that out of 22 observed traits, 8 traits show narrow variability, while 8 traits exhibit wide variability. One of the reasons for the narrow variability is due to yam bean flowers undergoing pollination before the blossoming of the flowers.

So far, post-harvest processing of people's coffee is usually always a drying process using sunlight, the drying process is usually carried out for 15 to 17 days until a moisture content of 18 to 20% is reached. But if the rainy season takes up to 3 weeks more and this results in the quality of the coffee being not good because it is moldy and smells bad. In post-harvest handling, especially the drying process remains a problem in the field. Post-harvest processing of coffee in the small and medium coffee industry usually uses several methods, including: honey process, honey wet hulling process, natural process, full wash process, semi wash process and wine process. In addition to the processing after harvest, the type of variety harvested also greatly affects the quality of the crop. Arabica and Robusta coffee plants provide different tastes, aromas, levels of acidity for coffee lovers so that there is competition for market interest which also encourages farmers to plant Arabica and Robusta coffee. The purpose of this research is to get the best post-harvest coffee processing method according to the taste expected by consumers. From the research that has been done, it can be concluded that the processing method greatly influences the taste of the coffee, both Arabica coffee powder and Robusta coffee powder. The best post-harvest processing of coffee according to the taste expected by consumers with the honey method for both Arabica and Robusta coffee. This is influenced by the mucilage in coffee beans containing mucilage which gives rise to its own taste in the final result of coffee powder.

Characterization of Farming System and Determinants of Adoption of Horticultural Enterprises in Achham, Nepal

Nepal's rural agriculture is characterized by its diverse and interconnected system of farming. The Ghaghara/Karnali river system in the northwest of Nepal represents the typical rural farming system. A study was conducted in 2019 in the Mid-hill district of Achham, Nepal in the same river system with the aim of studying the farming system, its features, and different factors that influence the horticultural enterprise adoption by the farmers. A total of 130 respondents were selected from the Panchadewal Binayak Municipality of Achham district of Nepal using the multi-stage purposive random sampling approach. Beside the characteristics of Farming system; various factors that determine the horticultural enterprise adoption were examined using the binary logit regression model. The integrated or multi-enterprise farming system was found to be dominated by three primary enterprises: horticulture, livestock, and agronomy. The pattern of household participation in each enterprise under study was substantially the same, with almost three fourth of the household choosing main grain crops, and horticultural crops especially vegetables; around 85% adopting livestock in an integration system, and only about 13% fruit trees. The study demonstrated that among the many factors under inquiry, the gender of household head, size of the family and visit by the extension workers influences the farmer’s decision on adoption of horticultural enterprise significantly. Though non-significant, age, level of education, farming experience, agriculture as primary occupation and credit facilities also positively plays the role in decision of horticultural enterprise adoption. Ethnicity, years of residence in same location, dependency ratio, total land size, training and visit to extension worker were negatively associated with farmers' decisions regarding horticulture enterprises. Thus, for the development of agriculture in rural areas with a higher adoption of horticultural enterprise which as higher potentialities in the rural agricultural system in Nepal, it is necessary to consider the role of various socioeconomic and personality variables in farmers decision to adopt the type of farm enterprise.

A 16-Year Retrospective Study Examining Socio-Demographic Factors among Suicide Decedents in Bolu Province, Northwestern Turkey

2023-08-09T09:22:46+00:00

This study aimed to examine the socio-demographic features of completed suicides in Bolu province, northwestern Turkey, between 2003 and 2019, using corpse examinations and autopsy reports to provide epidemiological data with a view to helping prevent suicidal behavior. Of the 108 suicides examined, males accounted for 84.3%, and females accounted for 15.7%. The suicide rate was the highest in the 25–34 age groups and among those of an unknown marital status. Suicide in an unknown location in the group aged 24 years and below was significantly higher than among age groups, while the workplace was significantly higher in those aged 35–64 years. In both genders, the home and its surroundings comprised the leading location of the suicide event, with an unknown location found to be significantly higher in males. The most common suicide method was identified as hanging, with no statistically significant difference between demographic groups with respect to method, and the highest suicide rate was observed in 2016–2019. With regard to time of year, winter was found to be significantly higher among those aged 24–34 years, whereas those aged 65 years and above were likelier to die in spring or summer (p=0.014). Several risk factors were identified, most of which could be detected and resolved before the suicidal act. Studies such as this are extremely valuable for their contribution to preventing suicide by identifying such risk factors.
