Chronic and Transitory Poverty in Pakistan: Evidence from a Longitudinal Household Survey

This paper analyses the incidence of chronic and transitory poverty in Pakistan in both urban and rural settings. The findings are that rural poverty is severer and also chronic as compared to transitory poverty in urban centres. The main factor behind this phenomenon is the homogeneity of the rural set-up which affects the employment and wage levels adversely. On the other hand, in the urban areas, heterogeneous population with diverse occupations provides better employment and wage opportunities. Furthermore, illiteracy, landlessness, lack of ownership of dwellings, and dependency on sharecropping are the main factors accentuating rural poverty. The paper also analyses the zakat element of the safety net strategy. Contrary to the prevailing perception that zakat does not reach the actually poor, it turns out that in fact zakat has become an identification mark for the chronic poor. The findings of this paper have significant implications for the poverty reduction strategy of the Government of Pakistan.Poverty, Chronic Poverty, Household Surveys Longitudinal, Pakistan

Performance evaluation of optical attocells configuration in an indoor visible light communication

Visible light communication VLC is deemed as futuristic technology applied for both illumination and data communication due to the low-cost energy consumption, long life expectancy, huge bandwidth, and high security compared to radio frequency RF. Uncovered area, minimum signal-to-noise ratio (SNR) and received power results from the non-uniform distribution of small base stations (i.e. Optical attocells) in the room. In this paper, the researchers propose a new LEDs distribution of five optical attocells configuration model in order to optimize the received power distribution and SNR at the center of the room for indoor VLC system. The optical attocells configuration in terms of received power to fill the uncovered area at the center of the room has been investigated. The simulation results showed that the proposed attocells configuration saved 24.9% of the transmitted power. Besides that, the whole room was covered uniformly. As a result, the received power and SNR are improved

ABSTRAKSI Berdasarkan arti harfiah, Animasi adalah menghidupkan. Yaitu usaha untuk menggerakkan sesuatu yang tidak bisa bergerak sendiri. Animasi juga merupakan sebuah rangkaian gambar yang di tampilkan secara bergantian melalui beberapa frame yang disusun secara urut sehingga menghasilkan sebuah gambar yang bergerak. Sejak jaman dulu, manusia telah mencoba menganimasi gerak gambar binatang mereka, seperti yang ditemukan oleh para ahli purbakala di gua Lascaux Spanyol Utara, sudah berumur dua ratus ribu tahun lebih. Masyarakat awam kini sering lupa apabila ditanya tentang sejarah nasional. Apalagi seiring dengan banyaknya budaya asing yang masuk ke negara kita, budaya dan sejarah nasional kita pun jadi ikut dilupakan. Masyarakat dan anak-anak di zaman sekarang ini malah lebih mengenal sejarah negara lain lewat animasi-animasi luar yang banyak beredar di televisi. Apabila anak-anak di tanya pahlawan seperti apakah yang mereka kenal. Mereka pasti lebih mengenal pahlawan animasi Jepang dan Amerika daripada tokoh pahlawan nasional. . Dengan gaya visual yang lebih mudah dipahami dan di padu dengan warnawarna yang colourfull ternyata membuat mereka lebih tertarik mengenal tokoh fiktif dalam serial atau film-film animasi yang tayang di televisi. Maka dirasa peran animasi ternyata punya andil besar dalam perkembangan anak-anak. Dan pelajaran sejarah juga sangat penting,apalagi anak-anak zaman sekarang kurang begitu mengenal apalagi tertarik mengenai pahlawan-pahlawan perjuangan. Maka dirasa melalui media animasi ini dapat memberikan sesuatu yang berbeda dengan merancang film animasi 2D dengan cerita yang menarik dan sesuai dengan anak-anak tentang kisah perjuangan Pangeran Diponegoro. Konsep yang dipakai adalah “Diponegoro Is My Hero”. Disini di ceritakan seolah Diponegoro adalah seorang pahlawan super hero. Agar dapat menarik minat anak-anak untuk lebih mengenal Pangeran Diponegoro nantinya. Kata Kunci : Animasi, Pahlawan Nasional, Diponegoro Is My Her

Removal of multiple artifacts from ECG signal using cascaded multistage adaptive noise cancellers

Although cascaded multistage adaptive noise cancellers have been employed before by researchers for multiple artifact removal from the ElectroCardioGram (ECG) signal, they all used the same adaptive algorithm in all the cascaded multi-stages for adjusting the adaptive filter weights. In this paper, we propose a cascaded 4-stage adaptive noise canceller for the removal of four artifacts present in the ECG signal, viz. baseline wander, motion artifacts, muscle artifacts, and 60 Hz Power Line Interference (PLI). We have investigated the performance of eight adaptive algorithms, viz. Least Mean Square (LMS), Least Mean Fourth (LMF), Least Mean Mixed-Norm (LMMN), Sign Regressor Least Mean Square (SRLMS), Sign Error Least Mean Square (SELMS), Sign-Sign Least Mean Square (SSLMS), Sign Regressor Least Mean Fourth (SRLMF), and Sign Regressor Least Mean Mixed-Norm (SRLMMN) in terms of Signal-to-Noise Ratio (SNR) improvement for removing the aforementioned four artifacts from the ECG signal. We employed the LMMN, LMF, LMMN, LMF algorithms in the proposed cascaded 4-stage adaptive noise canceller to remove the respective ECG artifacts as mentioned above. We succeeded in achieving an SNR improvement of 12.7319 dBs. The proposed cascaded 4-stage adaptive noise canceller employing the LMMN, LMF, LMMN, LMF algorithms outperforms those that employ the same algorithm in the four stages. One unique and powerful feature of our proposed cascaded 4-stage adaptive noise canceller is that it employs only those adaptive algorithms in the four stages, which are shown to be effective in removing the respective ECG artifacts as mentioned above. Such a scheme has not been investigated before in the literature

Ergonomic study on the manual harvesting tasks of oil-palm plantation in Indonesia based on anthropometric, postures and work motions analyses

Harvesting is the most important but burdensome work in oil-palm industries in which done manually by human power and skill. This research deals with analyses of anthropometry, work motion and posture on the harvesting tasks in the aims to understand ergonomic risks associated with the tasks and intervention needed in order to minimize the risks. A set of forty-two anthropometric dimensions and video records of work-motions were collected from a total sample of 141 male harvesting-workers from three different regions in Sumatera, Kalimantan and Sulawesi islands of Indonesia. The stature, height of eye and shoulder, and the length of arms were observed as the most relevant and critical anthropometry in designing the harvesting task and tool; and the height of the palm tree should be fully considered as well.  Motion analysis revealed that the push-cutting technique with a “dodos” (a chisel-like) tool effectively applied to harvest fresh fruit bunch (FFB) which height is less than 3 m, while the pull-cutting technique with an ‘egrek’ (a sickle-like) tool is the only applicable way to harvest FFB taller than 3 m.  The upper body segments such as neck, shoulder, back and arms were ergonomically vulnerable in most cases of the harvesting tasks. The results of RULA revealed that the work postures are outside safe ranges and further investigation and changes are required immediately. Finally, the results of work motion simulations could formulate tasking procedures that may minimize awkward posture and MSD risk.

Sustainable agriculture in Indonesia: Facts and challenges to keep growing in harmony with environment

The nature of agricultural production system in Indonesia is very diverse from shifting cultivation to intensive crop farming, from rain-fed to intensive-irrigated paddy field, from vegetables mix farming to monoculture industrial plantations, from subsistence small-scale farming to large-scale commercial plantation.  As the fourth most populous country in the world that is inhabited by 250 million people, agriculture plays a substantial role in Indonesian economy which generates close to half of total employment and accounts for about a fifth of GDP, as well as the very important contributor of export.  Notwithstanding the great potential resources and market demand, the sustainability of agriculture in the country remains challenging. The challenge is how to continue the agricultural development and economic growth that is needed to improve the quality of life and the basic needs of the growing population while at the same time to protect the environment by reducing the pressure on the carrying capacity.  Rapid pace of agricultural development in the last four decades –as well as the commercialization, industrialization and urbanization– has led to significant changes in agricultural production systems. In some regions, modernization ofagricultural technologies has increased production to keep pace with the population growth, but other problems in supply chain and distribution still plague many communities and regions. Concerning the current conditions of agricultural practices in dealing with the needs to improve productivity and at the same time to conserve the environment and natural resources, we need to adjust our understanding and formulate action strategies for developingagricultural practices  better and more sustainable future.  This paper discussed the present status of agricultural condition and practices in Indonesia as well as some challenges and strategiesto overcome

Tuning PID Controller Pada Sistem Eksitasi Alternator

Abstrak: Dalam pembangkitan tenaga listrik, kestabilan tegangan merupakan hal yang sangat penting untuk diperhatikan karena dapat mempengaruhi kestabilan sistem kelistrikan. Perubahan tegangan keluaran sebuah generator dipengaruhi oleh berbagai macam faktor diantaranya adalah beban dinamis dan tegangan penguat magnet (tegangan eksitasi). Untuk merepresentasikan pembangkit yang sebenarnya dirancang sebuah alternator sebagai modul praktikum yang dilengkapi dengan sistem eksitasi yang bekerja secara otomatis. Dengan program SIMULINK disimulasikan grafik tanggapan alternator pada setiap perubahan seting konstanta PID yang ditala secara tepat agarmendapatkan tegangan alternator yang stabil sesuai rating walaupun beban berubah-rubah.Respon sistem jauh dari harapan jika amplifier diberikan penguatan KA=1, sehingga KA dinaikkan hingga 45 tapi efeknya terjadi overshoot dengan waktu steady state 10 detik. Overshoot yang terjadi akibat kenaikan KA diperbaiki dengan memasang PID Controller dengan seting berdasarkan metode Ziegler-Nichols diperoleh Kp=1,05, Ti= 0,25, Td=0,12 bisa menekan overshoot tinggal 6 % dan waktu steady state kurang dari 1 detik.Kata-kata kunci: eksitasi, alternator, controlle
