The objective of this study is to find out the quality level of entrepreneurship development of the students and graduates in Vocational High School (VHS).  Methodologically, this study used ServQual (service quality) with 701 respondents from seven districts with cluster sampling method.  There are five instruments and dimensions in this study which are physical/tangible feature, reliability, responsiveness, credibility, and empathy. The whole data analyzed statistically by descriptive statistic and comparative analysis. The finding of this result is there is a significant difference between the respondents’ reality and expectation. It turned out with the average value of respondents' expectations of the 5 (five) dimensions of entrepreneurship service quality in which it is much higher than the average value of reality/perception. Therefore, it is concluded that the level of entrepreneurship service quality is not sufficient. From the five service dimensions, tangible and interest-responsiveness got the lowest assessment. The implication of the results is that it needs reinforcement for the five dimensions of the entrepreneurship development service in order to attain competitive-graduates. Moreover, the applying of ServQual model needs to be expanded in education and entrepreneurship services.   Received: 17 October 2021 / Accepted: 22 December 2021 / Published: 5 March 2022

The research is aimed producing the instrument of chemistry misconception at the atom structure concept as the instrument for categorizing the student’s misconception. This research is designed as research and development in according with Borg and Gall. The validity test of the instruments include validity of cuntructions, validity of content, validity of psychometrics and the legibility of the instrument. The research result showed that each individual students are categorized as fair with the average of 60,38%, the misconception of students is categorized a also fair in concept of electronic configuration (53,53%), in sub-skin (55,54%), in energy level (59,92%) and in those that is categorized high is in the concept of orbital (66,66%).Keywords: Instrument of chemistry conception, Atom structure

Abstract. The objective of this research was to found the optimum concentration of honey for sex reversal of male tilapia.   The  non factorial completely randomize design was used for this research, the factor that has been examined were honey concentrations at level of  0%, 0.05 %, 0.1%, 0.15 % and 0.2 % for 24 hours submersion. The data were subjected to Anova test and followed by BNT test. The results showed that the differences of honey concentrations was significantly influence the   percentage of male tilapia (P0.05), but did not affect significantly on the survival rates. (P0.05). In general, the percentage of male tilapia was increased with increasing the honey concentrations, where the higher percentage of male was found at 0.2 % (81.43%), and it was different significantly with other concentrations. It is concluded that 0.2% of honey is  suitable for male tilapia sex reversal.Keywords: Honey; Sex reversal; Tilapia (Oreochromis niloticus); Male; SubmersionAbstrak.   Penelitian ini bertujuan untuk  mengetahui konsentrasi madu yang efektif menghasilkan ikan nila (O. niloticus)  kelamin jantan yang paling tinggi. Rancangan Acak Lengkap (RAL) non faktorial digunakan dalam penelitian ini, faktor yang diuji adalah perbedaan konsentrasi madu, yaitu 0 %(kontrol), 0,05 %, 0,1 %, 0,15 % dan 0,2% ppt selama 24 jam perendaman. Hasil uji ANOVA menunjukkan bahwa perbedaan konsentrasi madu berpengaruh nyata terhiadap persentase nila jantan yang dihasilkan (P0,05), namun tidak berpengaruh nyata terhadap kelulushidupan baik selama perendaman maupun pemeliharaan (P0,05). Secara umum terlihat persentase kelamin jantan meningkat seiring dengan peningkatan konsentrasi madu dalam larutan perendam. Uji lanjut menggunakan BNJ memperlihatkan bahwa persentase nila jantan tertinggi dijumpai pada  konsentrasi 0,2% (81,43%±0,23), nilai ini berbeda nyata dengan perlakuan lainnya. Dengan demikian dapat disimpulkan bahwa konsentrasi madu 0,2% sesuai dan efektif untuk pengarahan jenis kelamin jantan pada ikan nila.Kata kunci: Madu;  Pengarahan jenis kelamin; Nila(Oreochromis niloticus); Jantan; Perendaman

This development research aimed to produce performance assessment instrument on chemistry learning for XI grade, descibe for characteristics, and validity tests. This research development used Dick and Carey’s model. The products consists of acid-base proved into worksheet, evaluation of indicators, direction of usage, sheet of observation, rubric of assessment, assessment of conversion, and value of recapitulation. Validation’s data of Aiken were 0,60 for unit one, unit two for 0,60, and 0,66 for unite three means valid. The data of experiment were 84% for suitability, 87% for simplicity, and 84% for usefullness. Application’ data for suitability, simplicity, and usefullness were 84%, 86%, and 84% respectively. Upper validity correlation table within 5% of significant level and reability inter-raters were 0,76 for unit one and 0,75 for unit two. Application of assessment’s instrument were positively responded by students. Therefore, instrument of assessment in 2013 curriculum-based stated applicable to be implemented in learning process.Keywords: Performance assessment-instrument, Applicable, Chemistry  learning
