"ABSTRAK Jurnal yang memfokuskan pada tulisan berapa penelitian interseksibidang ilmu sain, teknologi, seni, dan ilmu kemanusian serta implikasi sains teknologi dan seni terhadap kehidupan masyarakat"

"this article aims at describing the essay, how to compose them, and how to use scoring rubric or scoring criteria in assessing the students answers. there are some advantages and disadvantages of these tests. the main advantage because of its function to know about testee's competences in higher level thinking, such as: to analyze, to interpret, to sinthesize, to evaluate, and to predict something. this test is also effective in assessing complex learning outcomes, relatively easy to construct, and guessing is eliminated on the contrary it is difficult to be scored objectively because there is no common set of criteria for all students in essay tests, scores are as unreliable, well as effect or personal judgement, which can be catagorized as the disadvantages of essay test. to prevent the disadvantages, evaluates may use "the guidelines for writing clear essay questions "such as using keywords to specify thinking process, stating requirements clearly, indicate response length expected, setting time limits, and giving weights to questions. evaluators can also make scoring rubric to assess students answers to avoid unreliabilities."

"ABSTRAK GFRP (Glass-fiber Reinforced Plastic) merupakan material anisotropik, yang sifat mekaniknya tidak sama pada sumbu x,y dan z dibentuk oleh dua komponen utama yaitu serat penguat dan resin. Kombinasi jenis dan bentuk serat penguat maupun jenis resin memungkinkan adanya beberapa struktur GFRP dengan beban tertentu. "

"The research studied: which aggregate demand affected the national income -- it should be affected by an investment normatively -- and how the roles on economic development. The economic development was considered qualified when the development was not solely for the economic growth itself but also producing impact on social welfare: namely, higher emplyment and income percapita and lower poverly level.This research aimed so study: (1) the direction and the strength of the influence of consumption, investment and net export to growth of Gross Domestic Product (GDP), and (2) the direction and the strength of the influences of GDP growth on employment, income percapita, and poverty level. From both these objectives could be produced measurement model of aggregate demands role in improving employment and income per capita and decreasing poverty level through increased GRP growth."

"ABSTRAK Rancangan rangkaian pemancar dan penerima sensor ultrasonic ini menggunakan dua buah sensor ultrasonic sebesar 40 kHz. rancangan ini berfungsi untuk mendeteksi adanya pergerakan objek yang berada didepan sensor yang diletakkan berdampingan. Rancanfan alat ini diletakkan dalam ruangan tertutup seperti ruangan dalam mobil maupun ruangan dalam rumah. Alat ini melancarkan gelombang ultrasonic dari rangkaian pemancar ke suatu obyek kemudian gelombang tersebut dipantulkan kembali ke rangkaian penerima. Jika ada pergerakan obyek maka akna terjadi perubahan intensitas gelombang ultrasonic. Perubahan intensitas dari geolombang tersebut akan diubah menjadi suatu besaran listrik yang setelah melalui rangkaian penguat akan mengaktifkan buzzer. Rancangan alat ini menggunakan dua buah indicator yaitu buzzer yang akan mengeluarkan suara apabila terjadi pergerakan obyek serta lampu LED sebagai indiator pulsa ultrasonic yang diterima. Sensor ultrasonic ini mempunyai tingkat sensitifitas yang dapat diatur dengan menggunakan sebuah variable resistor. Frekuensi pancarannya dapat diatur dari frekuensi 34,28 kHz sampai 45 kHz. "
