IntisariTelah dilakukan pengujian kinerja akustik dan kinerja mekanik panel sandwich berbasis ampas tebu dan bambu. Pengujian kinerja akustik dilakukan secara eksperimen mengacu pada prosedur ASTM E-1050-98 dan kinerja mekanik menggunakan material testing machine. Pada penelitian ini dilakukan variasi ketebalan komposit ampas tebu dan pengaruh penambahan lapisan bambu di permukaan atas dan bawah komposit ampas tebu. Hasil penelitian menunjukkan bahwa pengaruh ketebalan sampel adalah menggeser penyerapan bunyi efektif pada frekuensi rendah sedangkan penambahan lapisan bambu pada komposit ampas tebu mempengaruhi penurunan nilai koefisien serapan bunyi yang dikarenakan tingkat kekerasan tinggi dan porositas rendah pada lapisan bambu. Adapun pengaruh ketebalan terhadap kinerja mekaniknya adalah menurunkan nilai MOR dan MOE sementara pengaruh penambahan lapisan bambu membuat nilai MOR naik dan nilai MOE turun. Pengaruh ketebalan dan penambahan lapisan bambu juga mengubah nilai densitas sampel. AbstractSound absorption performance and mechanical performance have been conducted in panel sandwich based bagasse and bamboo. The testing acoustic performance was conducted experimentally refer to ASTM E-1050-98 standard procedure and mechanical performance using a material testing machine. In this research, thickness variation bagasse composite and bamboo effect of adding a layer on the surface of the upper and lower composite bagasse. The results showed that the influence of the thickness of the sample is to shift the effective sound absorption at low frequencies while adding a layer of bamboo composite bagasse impairment affects the sound absorption coefficient due to a high degree of hardness and low porosity of the lining of bamboo. The effect of thickness on the mechanical performance is to lower the value of MOR and MOE while the effect of adding a layer of bamboo create value MOR MOE values rise and fall. The influence of the layer thickness and the addition of bamboo also change the value of the density of the sample. Pemanfaatan lain dari ampas tebu disajikan pada makalah ini sebagai salah satu alternatif material penyerap bunyi dalam bentuk komposit. Pengaruh ketebalan dan pengaruh penambahan lapisan bambu pada permukaan atas dan bawah komposit ampas tebu terhadap kinerja akustik dan kinerja mekanik telah dikaji berdasarkan pengujian eksperimen. Pilihan ka- * E-MAIL: iyahya@mipa.uns.ac.id jian atas kinerja akustik dan kinerja mekanik komposit ampas tebu dan bambu didasarkan pertimbangan bahwa komposit panel sandwich merupakan panel akustik lantai (ubin) yang dapat diaplikasikan pada bangunan. Oleh karena itu, perilaku dan respon akustik serta mekaniknya menjadi sangat penting untuk memenuhi standar yang berlaku untuk panel penyerap bunyi pada bangunan ISO 11654 [5].Kinerja serapan bunyi merupakan fungsi frekuensi yang umumnya dengan bertambahnya kinerja serapan bunyi efektif pada frekuensi tertentu dapat ditingkatkan salah satunya dengan menambahkan ketebalan [6]. Kinerja mekanik komposit panel sandwich menjadi san...

Peter Senge’s learning organization model, “The Five Building Blocks,” initiated five elements of learning organization, namely “personal mastery, team learning, shared vision, mental models, and systems thinking”. Inspired by this model, several developed learning organization models and the elements are proposed by the scholars in the last two decades in order to preserve the needs of the change world. The aims of this study are to analyse the development of learning organization models and the elements attached to the model. A systematic process of literature review is implemented as the methodology of the study which critically resulted ten journals to be investigated. According to the research, three scholars implemented the five building blocks model from Peter Senge, while the other scholars proposed their studies with developed elements and learning organization models. The characteristics, the readiness, the perception, and the existing conditions of the organizations are several factors that affect the learning organization model. While the differences in the level of how important each element in the learning organization model is also encourages the development of learning organization model itself. Heretofore, the Five Building Blocks model is still very relevant to be used by the scholars and become the basis of learning organization model research in the future.
