Abstract

Penelitian ini bertujuan untuk: (1) mengetahui karakteristik produk modul IPA terpadu yang berbasis PBL dengan tema fotosintesis, (2) mengetahui kelayakan produk modul IPA terpadu berbasis PBL dengan tema fotosintesis, (3) mengetahui peningkatan kemampuan berpikir kritis siswa setelah menggunakan modul IPA terpadu berbasis PBL dengan tema fotosintesis. Penelitian ini merupakan Research and Development (R&D). Pengembangan dilakukan dengan mengacu pada model 4-D dengan tahapan Define, Design, Develop, dan Disseminate yang dikemukakan oleh Thiagarajan. Pengembangan modul ini dinilai berdasarkan kelayakan isi, penyajian, dan bahasa oleh dosen, guru, dan peer review. Berdasarkan validasi kelayakan isi, penyajian, dan bahasa modul kemudian diujicobakan kecil pada 9 siswa. Setelah  direvisi, modul diujicobakan ke kelas. Kemampuan berpikir kritis siswa dianalisis dengan uji nonparametrik dua sampel berhubungan dengan uji Wilcoxon menggunakan software PASW Statistic 18. Hasil penelitian ini adalah (1) modul IPA terpadu berbasis masalah dengan tema fotosintesis dikembangkan menggunakan komponen pembelajaran berbasis masalah dengan menggunakan model 4-D meliputi Define, Design, Develop, dan Disseminate, (2) kelayakan modul IPA terpadu berbasis masalah dengan tema fotosintesis yang dikembangkan berkategori baik berdasarkan penilaian dari ahli, praktisi, dan respon siswa, dan (3) kemampuan berpikir kritis siswa setelah mengikuti proses pembelajaran menggunakan modul IPA terpadu berbasis masalah dengan tema fotosintesis mengalami peningkatan (sig.0,000). Besarnya peningkatan dilihat dari gain score pada 4 aspek kemampuan berpikir kritis meliputi aspek kelancaran 0,43 (sedang), aspek keluwesan 0,30 (sedang), aspek keaslian 0.35 (sedang), dan aspek memperinci 0,33 (sedang).

Hasil analisis menunjukkan bahwa, variabel gaya kepemimpinan (X1) diperoleh koefisien sebesar 0,339, t-hitung 2,045 dan nilai signifikansi 0,045 yang berarti jika variabel gaya kepemimpinan 1 satuan maka akan meningkatkan kinerja pegawai pada Satlantas Polres Kediri sebesar 0,339 satuan. Dengan kata lain kinerja pegawai akan meningkat sejalan dengan perbaikan gaya kepemimpinan pada Satlantas Polres Kediri. variabel budaya organisasi (X2) diperoleh koefisien sebesar 0,648, t-hitung 4,426 dan nilai signifikansi 0,000 yang berarti jika variabel budaya organisasi 1 satuan maka akan meningkatkan kinerja pegawai pada Satlantas Polres Kediri sebesar 0,648 satuan. Dengan kata lain kinerja pegawai akan meningkat sejalan dengan perbaikan budaya organisasi pada Satlantas Polres Kediri. Dan variabel gaya kepemimpinan (X1) dan budaya organisasi (X2) diperoleh nilai F-hitung 38,595 dan nilai signifikansi 0,000 yang berarti variabel gaya kepemimpinan dan budaya organisasi berpengaruh secara simultan terhadap kinerja pegawai pada Satlantas Polres Kediri.

Abstract

Leadership and organizational culture have an important role in improving employee performance. This study was conducted to examine how much influence the leadership style and organizational culture on employee performance. The purpose of this research is 1) To know the influence of leadership style on employee performance at Satlantas Polres Kediri; 2) To know the influence of leadership style on employee performance at Satlantas Polres Kediri; 3) To know the influence of leadership style and organizational culture simultaneously on employee performance at Satlantas Polres Kediri. This research uses quantitative approach. data collection was done through questionnaires distributed and executed on 68 employees at Satlantas Polres Kediri. Sampling to be used as respondent in this research is using purposive sampling method. The analysis used in this research is: multiple linear regression analysis, using research instrument test, classical assumption test, F test, and t test. The result of analysis shows that the leadership style (X1) variables are obtained coefficient of 0.339, t count 2.045 and significance value 0,045 which means if the leadership style variable 1 unit will improve the performance of employees at Satlantas Polres Kediri of 0.339 units. In other words the performance of employees will increase in line with the improvement of leadership style at Satlantas Polres Kediri. organizational culture variables (X2) obtained coefficient of 0.648, t-count 4,426 and significance value 0,000 which means if the organizational culture variable 1 unit will improve the performance of employees at Satlantas Polres Kediri of 0.648 units. In other words the performance of employees will increase in line with the improvement of organizational culture at Satlantas Polres Kediri. And the variables of leadership style (X1) and organizational culture (X2) were obtained F-count 38,595 and significance value 0,000 which means the variable of leadership style and organizational culture simultaneously influence the performance of the employees at Satlantas Polres Kediri.

Abstract

A plastic waste shredder is a tool used to shred or crush plastic into small pieces using a cutting knife mounted on a shaft connected via a pulley and belt transmission to a motor. This study is an experimental study to design a waste shredder with a more minimalist design that uses a 1000 RPM washing machine dryer dynamo drive motor, but aims to be able to participate in overcoming the current plastic waste problem. The results of the study showed that this machine with a 1000 RPM washing machine dynamo drive motor can only crush PET plastic beverage bottle waste that must be cut into pieces first to avoid stopping the machine and slipping material. Based on these results, it can be concluded that this machine is only intended for shredding thin PET plastic bottles.

Abstract

The increasing demand for efficient and precise manufacturing processes in the automotive industry has led to the development of automated assembly systems, including pneumatic-based tools. This study focuses on the design, development, and evaluation of a pneumatic Bush installation tool for motorcycle engine mounting production efficiency. The tool was tested against manual methods (hammer and jack) to compare installation time, accuracy, and defect rates (NG). A quasi-experimental approach was used, involving trial and error testing, prototype validation, and comparative analysis. The results showed that the pneumatic system significantly outperformed the manual method, with an 80% improvement in efficiency—reducing installation time from 120 seconds (manual) to 45 seconds (pneumatic). Additionally, Bush misalignment was reduced from 40% (manual) to 10% (pneumatic), while installation-induced defects dropped from 35% to only 5%. The findings demonstrate that the pneumatic-assisted tool provides more consistent pressure control, improved accuracy, and reduced error rates, making it a superior alternative to manual methods. This study contributes to the advancement of automated assembly technologies in the motorcycle manufacturing industry.
