Judul: Pengaruh Faktor Motivasi terhadap Prestasi Kerja Atlet Pencak Silat SEA Games
Abstrak: Pencak Silat telah dipatenkan sebagai Tradisi asli Indonesia oleh UNESCO. Pencak Silat selalu berada pada posisi tiga besar di ajang multi-sport event South East Asian (SEA) Games. Pada SEA Games 2017 kontingen Pencak Silat Indonesia berhasil mendapat posisi juara 3 secara keseluruhan, sementara pada tahun 2019 kontingen Pencak Silat Indonesia berhasil meraih posisi juara 1. Tujuan dari penelitian ini adalah (1) menganalisis persepsi atlet Pencak Silat SEA Games 2017 dan SEA Games 2019, mengenai faktor motivasi dan prestasi kerja (2) mengetahui pengaruh motivasi terhadap prestasi kerja atlet Pencak Silat SEA Games. Metode pengambilan sampel dengan purposive sampling. Alat analisis yang digunakan adalah analisis deskriptif dan regresi linier berganda. Berdasarkan hasil penelitian, atlet pencak silat SEA Games 2017 dan 2019 termotivasi untuk meningaktkan prestasi kerja. Faktor motivasi Need for Achievement paling berpengaruh signifikan dan positif yang berarti jika atlet diberikan kesempatan untuk meningkatkan kreatifitas, dan antusiasme untuk berprestasi maka akan meningkatkan variabel prestasi kerja.

Judul: Analisis Pengaruh Faktor – Faktor Motivasi Terhadap Kinerja Kerja Karyawan PT ExsaMap Asia
Abstrak: There are many ways to support company performance to be sustained, one of them is to take care the employees performance productivity. Employees work productivity will always be stable when employees have high motivation in work. There are many considerations to become parameter in measuring employees motivation levels so we can understand the impact of the motivation to performance work company.This research aims to (a) Study the condition of employees motivation work at PT ExsaMap Asia; (b) Identify motivation factors that influencing performance work at PT ExsaMap Asia; (c) Analyse the level of influence motivation factor that have an effect of the performance work employees at PT ExsaMap Asia; and (d) Study the condition of employees work motivation base on difference level of job at PT ExsaMap Asia. The relationship between motivation factor and performance of the employee will be analysis by using Rank Spearman Correlation and Multiple Regression. The analysis of the studies based on the condition of employees work motivation on difference level of job at PT ExsaMap Asia using Chi-Squared analysis. Rank Spearman Correlation examines three variabels from extrinsic factors that have relationship with performance, they are work friends relations variable, work place condition variable and supervision variable. From intrinsic factors there are two variables that have relationship with performance there are responsibility variable and development variable. Multiple Regression examines eleven variables that have influence to performance work employees at PT ExsaMap Asia there are development variable show the level of influence equal to 0,205 unit, regulation and policy of company variable show the level of influence equal to 0,176 unit, work friends relations variable show the level of influence equal to 0,157 unit, relation work between employees to superior variable show the level of influence equal to 0,152 unit, responsibility variable show the level of influence equal to 0,142 unit, work status variable show the level of influence equal to 0,138 unit, work place condition variable show the level of influence equal to 0,133 unit, work conducted variable show the level of influence equal to 0,128 unit, achievement variable show the level of influence equal to 0,122 unit, supervision variable show the level of influence equal to 0,118 unit and compensation variable show the level of influence equal to 0,102 unit. Chi-Squared analysis examines that at high management level show very high motivation equal to 25% and very high performance equal to 25%. At medium management level show very high motivation equal to 17,9% and very high performance equal to 32,1%. At low management level show very high motivation equal to 10,6% and very high performance equal to 34%.

Judul: Biodiesel production from palm oil in a bubble column reactor by non-catalytic process
Abstrak: Biodiesel has been defined as the monoalkyl esters of long-chain fatty acids derived from renewable feedstocks, such as vegetable oils and animal fats, for use in compression-ignition (diesel) engines. Biodiesel, consisting of fatty acid methyl esters (FAME) can be produced by transesterification of triglycerides (TG) and/or esterification of free fatty acids (FFA) in vegetable oils with short-chain alcohol, mainly methanol (MeOH). Alkaline-catalyzed transeseterification of TG in vegetable oils, with the addition of an acid-catalyzed reaction to esterify FFA are the technologies presently in use for industrial-scale biodiesel production. However, the desire to reduce or remove catalyst cost, waste output and to obtain the simpler process has stimulated the investigation of alternate methods of biodiesel synthesis.
