Judul: The Political Role of Youth in Rural Development
Abstrak: Pembangunan pedesaan harus melibatkan pemuda dalam setiap prosesnya. Keterlibatan pemuda bisa dilakukan dengan memberikan peran politiknya dalam tahap perumusan kebijakan, implementasi, hingga pengawasan. Peran politik pemuda adalah upaya yang dilakukan pemuda desa untuk memengaruhi kebijakan pembangunan di desanya. Penelitian ini bertujuan untuk mengenalisis pengaruh antara faktor internal dan eksternal individu terhadap peran politik pemuda dan menganalisis hubungan antara tingkat peran politik pemuda dengan pembangunan desa. Metode yang digunakan adalah metode kuantitatif menggunakan instrumen kuesioner yang didukung oleh data kualitatif berupa wawancara mendalam dengan para informan. Desa Babakan, Dramaga, Kabupaten Bogor menjadi lokasi penelitian untuk studi ini. Sebanyak 36 pemuda yang bergabung dengan organisasi kepemudaan yang ada di Desa Babakan menjadi subjek pada penelitian yang dipilih secara stratified random sampling. Hasil penelitian menunjukkan bahwa indikator umur pada faktor internal memiliki pengaruh negatif signifikan. Sementara itu pada faktor eksternal, hanya dimensi kebutuhan kondisional komunitas yang memiliki pengaruh positif signifikan dengan peran politik pemuda. Selain itu, peran politik tidak menunjukkan hubungan yang nyata dengan pembangunan desa., Rural development must involve youth in every process. The involvement of youth can be done by giving their political role in the stages of policy formulation, implementation, and supervision. The political role of youth is an effort made by youth to influence development policies in their village. The purpose of this study was to analyze the influence between internal and external factors of individuals on the political role of youth and to analyze the correlation between the level of the political role of youth and rural development. The method used was a quantitative method using a questionnaire instrument supported by qualitative data in the form of in-depth interviews with informants. Babakan Village, Dramaga, Bogor Regency was the research location for this study. As many as 36 youths who joined youth organizations in Babakan Village were the subjects of the research selected by stratified random sampling. The results showed that age had a negative significant effect on the political role of youth and external factors of youth had a positive significant effect on the political role of youth on the dimensions of the conditional needs of the community. Meanwhile, the role of politics did not show a significant correlation with rural development.

Judul: Toksisitas Kontak dan Efek Fumigan Minyak Atsiri Cinnamomum spp. (Lauraceae) terhadap Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)
Abstrak: One of the stored product pests which can reduce the quantity and quality of stored products is the flour beetle Tribolium castaneum. Stored-product pests are commonly controlled by fumigation and surface spraying using contact insecticides which can cause various harmful side effects. Essential oils of Cinnamomum spp. constitute safer alternatives for controlling stored product pests. This research was done to determine the contact toxicity and fumigant effect of essential oils of eight species of Cinnamomum and a commercial cassia oil against T. castaneum. A commercial insecticide containing alpha-cypermethrin was included for comparison. Only a commercial cassia oil had a fairly strong contact and fumigant effect, i.e. the treatment with 5% cassia oil caused 75% and 70% mortality, respectively. The other test essential oils were not active to weakly active against T. castaneum. Cassia oil and alpha-cypermethrin acted fairly fast, i.e. test insect mortality mostly occurred at 24 hours after treatment (HAT) and in the next 48 hours only a slight increase in insect mortality was noted. LC50 of cassia oil at 72 hours after treatment by contact and fumigant method was 4.73% and 3.12% respectively. Alpha-cypermethrin had relatively weak lethal effect by contact method and no fumigant effect at concentrations up to 10% but had strong knockdown effect at 5% and 10% by contact method.
