Tension Type Headache (TTH) merupakan jenis nyeri kepala primer terbanyak di dunia, diperkirakan sekitar tiga milyar orang mengalami kelainan nyeri kepala, 1.89 milyar dengan TTH dan 1.04 milyar dengan migraine. Pengguna smartphone di Indonesia diperkirakan sudah lebih dari 100 juta orang. Masalah kesehatan terbanyak yang pernah dilaporkan dari pengguna smartphone adalah TTH, yaitu 75,71% dari responden. Penelitian ini bertujuan untuk mengetahui hubungan posisi dan durasi penggunaan Smartphone dengan keluhan TTH pada mahasiswa Fakultas Kedokteran Universitas Mulawarman. Durasi dikategorikan menjadi lebih dari 3 jam dan kurang dari sama dengan 3 jam, posisi dikategorikan menjadi duduk dan berdiri. Penelitian observasional analitik dengan metode cross sectional ini menggunakan responden mahasiswa Fakultas Kedokteran Universitas Mulawarman yang terdiri dari angkatan 2017, 2018, dan 2019 sebanyak 141 orang yang dipilih dengan menggunakan teknik consecutive sampling. Analisis data menggunakan analisis univariat dan analisis bivariat. Dari hasil penelitian didapatkan sebanyak 77 orang (54,6%) mengalami TTH, 135 orang (95,7%) menggunakan smartphone dengan durasi lebih dari 3 jam, dan 103 orang (73%) menggunakan smartphone dengan posisi berbaring. Penelitian ini menunjukan tidak terdapat hubungan durasi penggunaan smartphone dengan nilai p=0,285 (p>0,05) dan tidak terdapat hubungan posisi penggunaan smartphone (p=0,114) dengan keluhan TTH.
Indonesia is well-known for having a vast and rich endowment of unique and genetically diverse biodiversity resources. Currently, initiatives are taking place around the world to generate DNA barcode libraries to make these data available to better understand biodiversity. The objectives of this study are to document DNA barcode research trends and detect the extent to which its application has evolved in Indonesia. The analysis was investigated using a compilation of 446 published papers, obtained from Harzing's Publish or Perish 8. The number of DNA barcode publication records has increased by a geometric average of 15.4/year. The number of studies involving molecular identification (30.1%), species and genetic diversity (10%), and evolutionary or phylogenetic studies (10%) appears to have driven much of the publication activity. The top three taxa studied include fishes (32.7%), plants (24.8%), and invertebrates (12.5%; except insects). We discovered that using a single molecular marker is still dominant (62.8%). We conclude that the practices of DNA barcoding data are likely to become a valuable resource in many sectors and focuses. However, the number of Indonesian DNA barcode records in public databases is relatively lower than in other mega biodiversity countries. The establishment of DNA barcoding initiatives and a national DNA barcode reference library in Indonesia would promote DNA barcoding applications to help conserve Indonesia biodiversity.

Longan (Dimocarpus longan L.) is not an indigenous fruit from Indonesia. Thus, the demands for this fruit were supplied by importing them from nearby countries such as Vietnam, Thailand, and China. Longan has been cultivated and developed in Indonesia in order to supply the local needs and to reduce the rapid flows of importing Longan. Recently, a brand new breed of local Longan has been engineered from Sleman District of D
<p>‘Nasubi’ eggplant seeds have occurred since 2018. In addition, plants that produce fruit phenotypic characters differ from those planted before the planting period in 2018. These three factors cause the decline in harvest rates and the current high increase in production costs. Observation of variations in phenotypic and molecular characters with ISSR molecular markers between seeds before 2018 and after 2018, became the first step for the research team to reveal information on the uniformity of phenotypic and molecular characters in eggplant ‘Nasubi’ from seeds purchased by farmers before 2018 and post-2018. The results of the molecular analysis with ISSR primary molecular markers namely UBC 809, UBC 815, IBC 880, UBC 888, and UBC 892, showed that the six samples had a high similarity index of 90% and resulted in a low polymorphism average of 12%. The results of the phenotypic analysis showed that eggplants from the seeds before 2018 and seeds after 2018 in this study had variations in the character of the leaf tip angle, leaf base, flower crown color, stamen color, young fruit color, fruit curve, and fruit tip shape.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
