July 6, 2022 エンジニアリングデザインⅡA

　こんにちは。白山麓高専事務室の間加田 侑里です。今回は、２年生のエンジニアリングデザインの活動について紹介します。
　２年生が履修するエンジニアリングデザインでは、地域の課題解決に取り組んでいます。白山麓は住民の少子高齢化による耕作放棄地の増加や猿による農作物への獣害が深刻化しています。本校ではSDGsで地方創生というテーマから地域活性化に着目し、学生たちはAIやIoTを用いて獣害対策に取り組む「獣害対策班」とサツマイモの生産販売とブランド化を行う「アグリビジネス班」の2チームに分かれ、校舎前の休耕田を活用して問題解決に挑んでいます。

 Hello, this is Yuri Makada from Hakusanroku Office. This time, I would like to write about what the 2^nd-year students have been doing in their Engineering Design class.
 In this class, students are working on solving local issues. In HAKUSANROKU (Foothills of Mt. Hakusan, below, Hakusanroku), the amount of abandoned farmland is increasing due to the aging population and decreasing birthrate. Also, monkeys are causing serious damage at the remaining farms. Our school is focused on local revitalization based on the goals of regional development found within the SDGs (Sustainable Development Goals). Students have been divided into two teams: the Animal Damage Prevention Team, which uses AI and IoT to tackle the animal damage prevention problem, and the Agribusiness Team, which produces, brands, and sells sweet potatoes, and students are trying to solve the problems by utilizing the fallow fields in front of the school.

「獣害対策班」

　白山麓では猿による農作物への被害が年々深刻化しています。そこで獣害対策班はAIとIoTを使い、自然の中でも猿を認識できるシステムの開発を始めました。一昨年には猿の写真をAIに数千枚学習させたことにより、認識信頼度を90%まで向上させることに成功しました。さらに、一般社団法人電気学会「U-21学生研究発表会」では最優秀賞を受賞しており、注目が集まっています。（詳しくはこちら）そして昨年からは、音と光による威嚇機能や、生産者が所有するスマホのLINEアプリに向けたアラーム通知機能の開発、検証を開始しました。（去年の活動の様子はこちら)
　昨年度の成果を基に、今年度はスマホのLINEアプリの通知機能で画像も通知できるようにさらに強化し、そして畑には映像を遠隔で確認できるIPカメラを複数台、学内にはデータ処理用のパソコンを設置し、カメラからの映像をパソコンに送ることで猿の映像を遠隔で処理するシステムを開発しています。また、音による威嚇についても開発中のシステムだけでなく、スピーカーを搭載したドローンを併用した威嚇効果も検証中です。

【Animal Damage Prevention Team】

 At Hakusanroku, damage caused by monkeys to crops is becoming more and more serious every year. This team has started to develop a system that uses AI & IoT that can recognize monkeys. In 2020, the team successfully improved AI recognition reliability to 90% by having the AI study several thousand photos of monkeys in nature. Furthermore, it has attracted much attention as it won the top presentation prize at the U-21 Institute of Electrical Engineers of Japan. (For more information) Last year, students began developing and testing a sound and light intimidation function and an alarm notification function for the LINE app on the smartphones owned by producers. (For more information on last year's activities )

 Based on the results of last year's activities, this year students are further enhancing the notification function of the LINE app so that it can also send photos as well as notifications. Then students will develop a system to remotely process monkey images by installing several IP cameras in the fields that can remotely check and process images of monkeys and send them to a PC on campus. In addition to the system under development, students are also testing the effectiveness of animal scarers in combination with a drone.

「アグリビジネス班」

　白山麓は住民の高齢化、担い手不足によって耕作放棄地が増加しています。アグリビジネス班でもこれらの土地を活用した地域活性化を目標に、持続可能なビジネスモデルの考案と検証をするため、サツマイモ「紅はるか」の栽培から広告、宣伝を含む販売計画の立案、企業経理まで、農業法人のビジネスシミュレーションを実践しています。　
　4月下旬、地元の方にトラクターと耕運機の操作方法を学び、校舎前の畑を耕しました。学生たちはトラクターを運転するのが初めてなため、真剣な眼差しで運転をしていました。地面の凸凹に、学生からは「ガタガタな道を運転している親の気持ちが分かった！」と声が上がりました。その後、紅はるかの苗を300株植え、畑の周りに獣害対策用のワイヤーメッシュ、そして獣害対策班と協力し電気柵を設置しました。収穫は９月末を予定しており、その間は、草刈りや水やりを交代で行い畑の管理をしていきます。
　また今年度は地域活性化の一環として、地元の白山麓地域活性化協議会が実施するアサギマダラのマーキングイベントにおいて、地元の方の協力のもと、アサギマダラに関するオリジナル商品を開発し販売を行う予定です。

【Agribusiness Team】

 The amount of abandoned farmland is increasing in Hakusanroku due to the aging of the local population and the lack of farmers. With the goal of revitalizing the region by utilizing these lands, the Agribusiness Team is also devising and verifying a sustainable business model through a business simulation of an agricultural corporation. This involves the cultivation of Beniharuka sweet potatoes and makings sales plans including advertising, promotion, and corporate accounting.　
 In late April, a local farmer taught students how to operate a tractor and cultivator and they plowed a field in front of the school. It was the first time for the students to drive a tractor and they took it very seriously. When the ground was uneven, one of the students said, “Now I understand how my parents feel when they drive on bumpy roads!” After that, they planted 300 Beniharuka seedlings, installed wire mesh and an electric fence, in cooperation with the animal damage prevention team, around the field to prevent damage from animals. Harvest is scheduled for the end of September, and during that time, the students will take turns mowing the grass around the field and watering the plants.
 This year, as a part of the local revitalization efforts, students plan to develop and sell original products related to the chestnut tiger butterfly at the chestnut tiger butterfly marking event held by the local Hakusanroku Community Revitalization Council, in cooperation with local residents.

　6月2日（木）、アグリビジネス班は白山麓キャンパスから車で3分ほど先にある里山総合会社「山立会」にお邪魔し、社会見学と毛刈り体験を行いました。
　山立会は白山麓で新規事業を立ち上げ、里山を舞台に農業や商品開発・販売・野生動物管理などの多角的な取り組みをされています。また、石川県の白山麓に増加しつつある耕作放棄地を活用し、羊たちの野草放牧を始め、現在は石川県立大学と連携しながら飼育技術の確立にも取り組まれています。
　代表の有本 勲氏は白山麓の観光と農業に着目し、白山麓には観光スポットがなく特産品の肉もないことなどから、羊の放牧や羊肉に可能性を感じ、白山麓の新たな特産品開発に向けて事業展開しています。有本氏から学生たちは羊飼育の年間スケジュール、飼料計算、収支計画、経営方針や羊の飼育方法などの説明を受けた後、山立会から車で10分ほど先にある鳥越地区の羊小屋で、羊担当の山本 真奈未氏の指導のもと、羊の蹄切りと毛刈り体験を行いました。羊の体重は100kgぐらいあり、歩き回る羊を捕まえるだけでも一苦労のようでした。3名の学生が羊を取り囲み、小屋の外へ誘導し、それからハサミを使って蹄切りと毛刈りを行いました。学生からは「ハサミで毛を刈る作業よりも、左手で毛を抑えるほうが重くて力が必要だから大変！」や「羊の毛はふわふわしていて、油っぽい！」との声があがりました。また、草本 留嘉寿さんは、寮生活の中で学生の散髪を頻繁に行っているそうで、羊の毛もハサミで刈ることはお手の物だと話していました。

　学生たちが活動している同じ白山麓地域で新規事業を立ち上げた山立会から経営に関するノウハウを学ぶとともに、羊の毛刈り体験を通して、新しい働き方や仕事の意義を考える良い機会を得られたと思います。ここ白山麓地域には、人口減少や獣害被害、文化継承など、今の社会における課題を多く抱えています。現在は、地域活性化の問題を地元のみなさんの協力を得ながら、共に考えることができるという、将来を担う学生にとって、絶好の学びの環境になっています。

 

 On Thursday, June 2^nd, the Agribusiness Team visited Yamadachikai, a mountain village landscape company located 3 minutes by car from the Hakusanroku Campus, for a social tour and sheep shearing experience. 
 Yamadachikai has established a new business in Hakusanroku and is engaged in multifaceted activities such as agriculture, product development, sales, and wildlife management in the mountain village landscape area. In addition to utilizing the increasing amount of abandoned farmland in Hakusanroku, they have begun grazing sheep on wild grass, and are currently working to establish breeding techniques in cooperation with Ishikawa Prefectural University.
 Mr. Isao Arimoto, the representative of the company, focuses on tourism and agriculture in Hakusanroku. Since there are no tourist spots and no specialty meats from Hakusanroku, he sees potential in sheep grazing and mutton, and is developing a business to develop new Hakusanroku specialty products. Mr. Arimoto explained to the students the annual schedule of sheep farming, feed calculations, income and expenditure planning, management policies, and sheep breeding methods. After that, they went to a sheep pen in the Torigoe area, about 10 minutes by car from Yamadachikai, to experience hoof trimming and sheep shearing under the care and guidance of Ms. Manami Yamamoto, who is a shepherd. Each sheep weighed about 100 kg, and it was a challenge just to catch them as they roamed around. 3 students surrounded the sheep, led them out of the shed, and then trimmed their hooves and sheared their wool. Students commented, "It was more difficult to hold the fleece with my left hand than it was to shear. The fleece is very heavy and requires more strength,” and "Sheep's wool is fluffy and oily!” Lucas Kusamoto, who frequently gives students haircuts in the dormitory, said that because of giving haircuts he is very good at shearing sheep.

 I think the students had a good opportunity to learn management know-how from Yamadachikai, which has launched a new business in the same Hakusanroku area where the students are working, and to think about new ways of working and the meaning of work through the sheep shearing experience. Here in the Hakusanroku region, we are faced with many issues in today’s society such as population decline, crop damage by animals, and passing on cultural practices. Now, with the cooperation of local residents, we are able to think about regional revitalization issues, which is an excellent learning environment for students who will be responsible for our future.
