Intellectual Property Theft

In this work, we examine the privacy and safety issues of Internet of Things (IoT)-based Precision Agriculture (PA), which could lead to the problem that industry is currently experiencing as a result of Intellectual Property Theft (IPT). Increasing IoT-based information flow in PA will make a system less secure if a proper security mechanism is not ensured. Shortly, IoT will transform everyday lives with its applications. Intellectual Property (IP) is another important concept of an intelligent farming system. If the IP of a wise farming system leaks, it damages all intellectual ideas like cultivation patterns, plant variety rights, and IoT generated information of IoT-based PA. Thus, we proposed an IoT enabled SDN gateway regulatory system that ensures control of a foreign device without having access to sensitive farm information. Most of the farm uses its devices without the use of its integrated management and memory unit. An SDN-based structure to solve IP theft in precision farming has been proposed. In our proposed concept, a control system integrates with the cloud server, which is called the control hub. This hub will carry out the overall PA monitoring system. By hiring the farm devices in the agricultural system, these devices must be tailored according to our systems. Therefore, our proposed PA is a management system for all controllable inputs. The overall goal is to increase the probability of profit and reduce the likelihood of IPT. It does not only give more information but also improves information securely by enhancing the overall performance of PA. Our proposed PA architecture has been measured based on the throughput, round trip time, jitter, packet error rate, and the cumulative distribution function. Our achieved results reduced around (1.66–6.46)% compared to the previous research. In the future, blockchain will be integrated with this proposed architecture for further implementation.

Buru Regency is one of the rice suppliers in Maluku Province.The achievements of Buru Regency as Maluku rice supplier cannot be separated from its history as a place for people who were exiled in 1969. The presence of these former people has an influence on social change in Buru Island. Located in Waeapo district, Buru regency, this qualitative research was conducted to explain social change in Waeapo, Buru by the former exiles. The results showed that before the former exiles arrived at Buru Island, the Waeapo was dominated by forests, where the local people practiced swidden agriculture. The presence of former exiles in 1969 changed the landscape of Buru from forest to paddyfields by means of forced labor. The forced labor and introduction of new agricultural system are patterns inherited from the colonial government. Nevertheless, in Buru, the harvest was consumed by the exiles instead of handed over to the government as a custom enforced by the colonials. The change in land use eventually changed the shifting cultivation system to permanent agriculture with the lowland rice farming system which is commonly practiced in Java. Ex-exiles were the people used by the New Order government to carry out development in remote areas in the 1969-1979 era until the change of Buru’s landscape, source of staple food, and cultural diversity exist in Waeapo..

The Cost

The book argues that all eighteenth-century farmers sought first and foremost to provide basic subsistence for their families. The first aim of all farmers was self-provisioning. Even large planters who exported tobacco or wheat and purchased luxuries sought to provision themselves with their own labor on their own land. All farmers also engaged in trade to obtain what they could not make for themselves. They were subsistence and market farmers at the same time. Besides providing for themselves year by year, farmers hoped to set up their children on farms. With older children coming into the workforce, farmers could acquire enough to provide for those children as they left the family. Tragically, family farming with its assurance of security required ever more land, resulting in the relentless expulsion of Native Americans from their possessions. Within this basic North American farming system, agricultural regimens differed greatly from section to section. Slavery prevailed from Georgia to Maryland because warm winters allowed farmers to use their work force all year around, justifying the cost of slaves. From Pennsylvania northward, farmers relied on family or on cottagers who could be dismissed in winter.The cultural and political division between North and South corresponded to the contours of the climate-based growing season. This agricultural system changed little until after 1800, when the growing urban populations motivated farmers to develop new and more profitable crops. Farmers benefited from expanding markets which enabled them to purchase the goods necessary to achieve middle-class respectability. Although gradually eroded, self-provisioning persisted until after World War II, when it was largely abandoned.

Organic Farming System

Excessive use of inorganic chemicals results in adverse impacts on land and plants. In the midst of the community, there is anxiety about the high content of pesticide residues in agricultural products. There is a need to develop alternative farming systems that are able to produce quantities and quality of healthy products in a sustainable manner. One agricultural system that supports the concept is the organic farming system. The basic principles of organic farming are: (1) Keeping the ecosystem healthy, (2) Applying the principle of efficiency to the cultivation system, (3) Conducting production activities with the concept of sustainable agriculture, (4) Producing pesticide-free products, and (6) Maintaining environmental sustainability. Food Crop Production Study Program Lampung State Polytechnic makes Organic Agriculture as one of the leading competencies for its graduates. The establishment of the Organic Agriculture Business Unit on campus will increase student competencies, foster entrepreneurship, be a place for competency internships, and as an independent source of income.

Abstract Agroforestry is a form of an agricultural system that is adaptive to climate change. Based on the institutional form, the farming system developed under the social forestry program is agroforestry. This form of agroforestry is the essential capital for farmers to establish in their cultivated lands further. This study aim to determine agroforestry farmers’ perceptions in the Upper Citarum Watershed on climate change and the adaptation activities. The sample farmers are a sub-set of farmer households sample in the socio-economic survey conducted by ICASEPS – ACIAR in the collaborative research in 2019. The reliability of the data on variables that reflect farmers’ perceptions of adverse shocks experienced, which directly or indirectly related to climate changes, is tested with Cronbach’s Alpha. Data analysis is performed by cross-tabulation, while multiple regressions are used to determine the effect of social forestry cultivated areas on farmers’ income. The results show that more than 55 percent of farmers participating in social forestry say that since the last ten years climate patterns are increasingly unpredictable. The most negative impacts of climate change impacts are indirect effects which are pests and diseases. Popular adaptation are reactive ones, namely increasing the use of pesticides and more intensive use of inorganic fertilizers. Farmers adaptation which are more synergistic with mitigation such as organic farming or cultivation of perennial crops are still relatively low. The increase in the arable land area due to social forestry has significantly increased farmer’s household income. Referring to this phenomenon, conducive policies to increase farmer participation in these adaptation actions are needed.

This research used a qualitative approach through in-depth interviews, observation, and document evaluation from June until November 2019 on the Kasepuhan Ciptagelar society. The data analysis of this study was completed through a process of reduction, verification, and conclusions. Local wisdom at Kasepuhan Ciptagelar contains environmental education values; physical, social, and cultural-environmental educations. It shows from their attachment to nature where the laws and natural cycles become their benchmark in the agricultural system used. Activities related to the society farming system are still implemented collectively to strengthen ties between residents through cooperation, which is a characteristic of their social-environmental education and seen from cultural-environmental education. It is closely related to a series of customary rituals that must be carried out by the Kasepuhan Ciptagelar agricultural activity.
