A common technique of vibration spectrum analysis is used for fault diagnosis of rotating machine in industry. The technique, however, requires a significant man power and has the risk of the direct measurement of vibration signal. This paper presents a remote maintenance technique based on acoustic emission of rotating machinery. The mixing matrix and the source signals are estimated using PARAFAC source separation by performing PARAFAC decomposition algorithm, permutation, and capon beamforming. This proposed technique prove the suitability and effectiveness of acoustic emission technique to diagnose Ball Pass Frequency of The Outer Race (BPFO) defect and misalignment coupling motor to pump.

Every company has to develop their managerial capability to maximize performance of every function in order to survive in an environment with drastic changes right now. This research was conducted at two governments owned manufacturing companies to compare the differences in managerial innovation. The method to assess the managerial innovation was based on elements of management function, which are planning, organizing, leading, controlling and coordinating. There were two methods in collecting the data, using questionnaire and doing observation. Questionnaires results were calculated using BPMSG AHP online system, to determine the score. The higher score of managerial innovation, the higher potential of the company to innovate. Managerial innovation score were 42.3% and 48.9%, which showed that none of them were innovative based on the previous research standard, which stated that innovation potential should be more than 50%. The differences between the two were also analysed based on every management function.

Lack of mass transit facilities in urban area leads motorcycle to become the most chosen vehicle mode in Indonesia. It accounts for approximately 80% of the total motorized vehicle population. Increasing in motor vehicle population causes traffic congestion and lower traffic speed, hence higher emissions that worsen urban air quality. This paper aims to investigate relationship of vehicle travelling speeds and CO2, CO and HC emission profiles of the typical motorcycle used in Indonesia. Exhaust emissions of 20 motorcycles were tested using autocheck analyzer on idle and speed variations of, 10, 20, 30, 40, 50, and 60 kph on a chassis dynamometer. For idle condition average emission rates of CO2, CO and HC were 0.16, 0.03 and 0.002 g/s, respectively. The results show that the highest CO2 and HC emissions of 82.30 g/km and 0.55 g/km, respectively, found at 10 kph. The lowest emissions were found at 60 kph speed with CO2 emission rate of 27.03 g/km and HC of 0.10 g/km. Carbon monoxide (CO) showed slightly different emission pattern, with 12.85 g/km found at 20 kph and 4.18 g/km at 50 kph. In general, the result shows that the higher the speed the lower the CO2, CO, and HC emissions. Emission profiles indicate that the speed between 30-50 km/h could be recommended as the most suitable traffic speed in urban area to ensure mobility, safety as well as the lowest emissions. The results are valuable as input to transportation management as a part of environmentally sustainable transportation.

In the last decades construction activity has been heavily criticized for its productivity and performance in relation to cultural differences. There have been several studies indicated that the cultural diversity influence the knowledge of the organization, and that result in barriers in knowledge sharing in the multicultural organization. The knowledge spreading manners affected by the cultural in organization due to ethnic, cities, sexual category, local culture, which that might lower level of the knowledge spreading in organization . Therefore, a research study is developed in order to assess the influences of cultural differences on the activity of knowledge distribution in organization project and to determine of extend of the cultural differences to obstacle the individual to share their knowledge within the organization or with other members of the organization and how is that leads to decrease the project’s performance. For seeking to achieve the aims of the study a survey questionnaire was used to gather data. System dynamic simulation is utilized to interpret the collected data in order to achieve meaningful information. The results proven that cultural difference is one of the major problems that impact the project performance negatively in the construction industry since it is verified that the cultural difference impacts the knowledge flow among the employees in the construction project which that strongly affects the outcome of the projects and that also leads to decrease the productivity of the project. In addition, the respondents also agree that cultural differences cause unsuccessful safety system in the construction projects. Therefore, the cultural differences should be given careful attention to ensure better project performance.

Di zaman era globalisasi ini kesempatan terbuka lebar bagi warga negara untuk memperoleh kesempatan yang sama dalam segala bidang, baik itu kaum laki-laki maupun kaum perempuan’ Jumlah kaum perempuan khususnya di Indonesia lebih banyak daripada jumlah kaum laki-laki dari total penduduk. Dengan jumlah perempuan yang demikian besar maka potensi perempuan perlu lebih diperhatikan dan diberdayakan sebagai pelaku untuk berkonstribusi dalam pembangunan bangsa kita. Perempuan sebagai hamba Allah yang lemah, memiliki peran amat besar dalam kehidupan bermasyarakat dan bernegara. Tanpanya kehidupan tidak akan berjalan semestinya. Sebab perempuan adalah pencetak generasi baru. Apabila di muka bumi ini hanya dihuni oleh kaum laki-laki saja kehidupan mungkin sdh terhenti beribu-ribu abad yang lalu. Oleh sebab itu, perempuan tidak bias diremehkan dan diabaikan karena dibalik semua keberhasilan dan kontinuitas kehidupan di situ ada perempuan.. Peranan perempuan dalam keluarga sangat penting. Perempuan merupakan banteng utama dalam keluarga. Peningkatan kualitas sumber daya manusia dimulai dari peran perempuan dalam memberikan pendidikan kepada anaknya sebagai generasi penerus bangsa. Keluarga merupakan awal pendidikan dasar. Dengan demikian jika dikelompok terkecil (keluarga) sudah bagus nanti akan merambah ke lingkungan masyarakat dan bangsa.

Pengembangan Teknologi Purifikasi Biogas (Kandungan Gas H2S Dan CO2) dengan Mempergunakan Kombinasi Wet Scrubber-Batu Gamping Totok Soehartanto; Sarwono Sarwono; Ronny Dwi Noryati

Biogas yang diproduksi dari hasil fermentasi kotoran ternak melalui bioreactor anaerob 60%-70% berupa gas methane (CH4), sekitar 30% berupa gas CO2 dan sisanya berupa gas H2S serta gas-gas lainnya. Gas CO2 jika terbakar berdampak terhadap lingkungan (hujan asam), sedang gas H2S bersifat korosif. Sehingga biogas hasil ekstraksi kotoran ternak perlu dipurifikasi agar ramah terhadap lingkungan dan aman buat peralatan (kompor gas). Metode pemurnian mempergunakan kombinasi water scrubber dan batu gamping, hal ini dikarenakan water scrubber efektif untuk mengurangi gas H2S sedang batu gamping efektif untuk menyerap gas CO2. Metode kombinasi ini telah diterapkan untuk pemurnian biogas hasil ekstraksi biogas dari kotoran ternak di kelompok peternak sapi di Nongko Jajar, dimana warna api yang dihasilkan dari pembakaran biogas hasil purifikasi biru sedang warna api biogas yang tidak dimurnikan bercampur dengan warna merah. Disamping itu air yang keluar dari water scrubber berbau belerang dan warna batu gamping berubah menjadi kuning. Sehingga pada makalah ini dipresentasikan design pengembangan filter purifikasi biogas, dalam hal ini water tidak lagi di spray-kan akan tetapi dirubah dalam bentuk kabut untuk mengefektifkan kontak antara biogas dengan kabut. Filter batu kapur berjumlah 2 buah, akibat batu gamping akan mengalami kejenuhan setelah dipergunakan dalam interval waktu tertentu.
