Lecturers have broad autonomy in developing instructional. With the characteristics possessed by these lecturers, collaboration between lecturers (team teaching) is a challenge that is sometimes not easy. However, in vocational learning, lecturer cooperation in learning is something that cannot be avoided. In the Classroom Action Research to SMK, researchers collaborated at partner schools of SMKN 5 Surakarta and SMKN I Mondokan Sragen. The type of research used is ethnographic research, which is a qualitative observation method used in social science that focuses on field studies and their interactions, and sees everything as unique. The method used in conducting the evaluation is the equivalent test, which is a test that aims to measure its reliability identically with the reference test. The conclusion that can be drawn in this PDS program is to complement each other's strengths and weaknesses in organizing the learning process for SMK. Pamong teachers who work together are senior teachers who have eaten a lot of salt in their teaching. Pamong teachers have adequate competence in teaching and educating students, on the other hand, senior teachers have limitations in developing learning innovations. This is where the role of PDS lecturers in completing the shortage of teachers. The innovation that the lecturers did was to provide guidance using e-learning in learning at SMK. This e-learning has many advantages in learning the millennial generation. By maintaining student motivation, the learning objectives will be better achieved.

Banana fruit is one of main product of Lampung Province. Banana is commonly utilized as raw material of banana chip production and its peel can be converted into bioethanol. The Objectives of this study were to find out the optimum treatments of hydrolysis and fermentation for producing bioetanol. Two steps, namely hydrolysis and fermentations, were carried out in this study. In the hydrolysis step, two treatments - H2SO4 consentration and hydrolysis duration – were implemented. The H2SO4 concentration treatment consisted of five level (0, 0.025, 0.050, 0.075, and 0,100 M); and the hydrolysis period treatment consisted of two level (15 dan 30 minutes). Bioethanol fermentation was carried out at room temperature for 72 hours with Saccharomyces cerevisiae as starter at concentration of 0%, 5%, 10%, and 15% (w/v). The treatments were arranged in Randomized Complete Block Design (RCBD) with three replications. Before and after hydrolysis, the cellulose, hemicellulose, and lignin contents of banana peel were determined. The reducing sugar concentrations were measured after hydrolysis, and bioethanol concentrations were measured after fermentation. The data of the cellulose, hemicellulose, lignin, reduced sugar, and bioethanol were tabulated and analyzed descriptively. The results of this study showed that the optimum treatment for hydrolysis was H2SO4 solution at a concentration of 0.050 M at 1210C for 15 minutes. The treatment yielded reduced sugar at a concentration of 11,26mg/100 mL. The optimum treatment for fermentation was a starter concentration of 10% (w/v) which produced bioethanol at a concentration of 0.03% (v/v). Keywords : banana peel, bioethanol, hydrolysis, H2SO4, reducing sugar.

Museum Jawa Tengah Ranggawarsita adalah salah satu tempat yang memiliki banyak koleksi objek bersejarah. Objek-objek bersejarah tersebut memiliki informasi penting di dalamnya. Informasi bisa berupa sejarah bangsa atau peradaban penting yang ada di Indonesia. Namun pada kenyataannya informasi mengenai objek bersejarah yang ditampilkan masih kurang jelas, detail dan informatif. Hal ini karena banyaknya informasi dari objek yang perlu ditampilkan dan dikenali oleh petugas kajian museum. Administrasi objek-objek museum juga masih menggunakan cara manual yaitu menggunakan arsip fisik untuk setiap informasi objek yang ada. Diperlukan sebuah sistem untuk mempermudah proses administrasi dan penampilan informasi objek dengan mengenali objek. Pengenalan objek menggunakan Near Field Communication pada android smartphone dan tag pasif Radio Frequency Identification dapat menjadi solusi dari permasalahan ini. Untuk pengunjung, sistem dapat digunakan untuk mengenali objek yang diinginkan dan menampilkan informasi objek secara detail, jelas dan informatif, sedangkan untuk petugas museum sistem dapat digunakan untuk administrasi objek-objek museum yang ada. Sistem dikembangkan dengan menggunakan proses pengembangan perangkat lunak unified process dalam satu iterasi. Sistem memanfaatkan web-service untuk sebagai penyedia atau perantara data sistem. Sistem sudah melewati pengujian black-box dan white-box dengan hasil lulus uji. Sistem diharapkan dapat mempermudah proses pengenalan objek museum dan administrasi objek museum.

Krisan merupakan tumbuhan yang termasuk dalam familia Acanthacea yang hidup pada dataran tinggi dengan iklim tropis atau sub tropis. Krisan digunakan sebagai obat herbal karena mengandung senyawa flavonoid dan alkaloid yang digunakan sebagai anti antibakteri, antiinflamasi, antioksidan. Berdasarkan pendekatan anatomi dapat diketahui bahwa tumbuhan mensintesis dan menyimpan senyawa bioaktif melalui sel-sel dan jaringan yang terspesialisasi. Salah satu sel, dan jaringan yang terspesialisasi untuk mensekresi metabolit sekunder adalah trikoma. Trikoma dapat dibagi menjadi trikoma glandular dan non glandular. Trikoma glandular dapat menyimpan dan mensekresi metabolit sekunder pada tumbuhan, sedangkan trikoma non glandular tidak dapat mensekresi metabolit sekunder. Tujuan dari penelitian ini adalah mengetahui bentuk, dan jenis trikoma pada varietas krisan fiji kuning, fiji putih, jimla kuning, puspita nusantara dan barcadi. Penelitian ini menggunakan metode leaf clearing pada sepal dan petal bunga krisan, kemudian dilakukan pengamatan dengan optilab. Pada penelitian ini ditemukan bahwa terdapat lima jenis trikoma glandular dan dua jenis trikoma non glandular. Dari penelitian yang telah dilakukan dapat disimpulkan bahwa terdapat tujuh tipe trikoma yang ditemukan pada lima varietas krisan yang diuji dan setiap varietas krisan memiliki jenis trikoma yang berbeda.
