This issue of Planning Malaysia Journal includes a mixture of articles addressing various issues in contemporary urban planning. Article 1 raises the question of whether green initiatives in educational institutions, especially universities, were successful in producing green graduates. A survey among green and non-green universities students showed that there is no significant difference in the level of perception, attitude and responsible environmental behaviour between green and non-green universities graduates. Thus, it suggests that students’ involvement in universities’ green initiatives should be increased.Article 2 discusses the impacts of street urban design on the perceived safety by women respondents. As women’s role in the cities becoming more pronounced, the authors suggest that streets and urban design should consider the safety of women so that street can become a safe and highly utilised public space. Article 3 looks at the factors affecting house prices in Malaysia in order to determine the alternative benchmark for Islamic home financing scheme. It shows that house price index are influenced by economic growth, demand for housing loan and construction materials. Article 4, in the meantime, compares the Islamic home financing schemes on offer in Malaysia nowadays, and suggest that there is a need for banks to move on from the Al-Bay Bithaman Ajil to Musharakah Mutanaqisah Partnership housing financing scheme.Article 5 looks how innovative management of natural resources leads to increased participation of the local community and improved revenue for rural businesses. These, in turn, motivates local stakeholders to continue preserving the resources. Article 6 examines the practices regarding food waste management in hotels in Langkawi. It found that there was a lack of emphasis from the hotels on their policy related to wastage of food and unsustainable food consumption pattern by their guests. This reflects on the lack of practices towards sustainable food waste management by the hotel sector.Article 7 identifies changes and threats to Malay landscape preservation in traditional Malays houses in Melaka and Kelantan. It concludes that threats to such preservation include inappropriate use of garden space, problems regarding house ownership, inadequate fund for maintenance, and current development trend that leads to traditional Malay garden setting being replaced by modern setting.Article 8 discusses the use of agroforestry approach to improve sustainability of oil palm smallholdings. Rapid development and expansion of natural forest into oil palm land has decreased the agricultural sustainability of Malaysian oil palm production. However, the article shows that sustainability of oil palm smallholdings can be improved through agroforestry, which at the same time was found to also improve income of the smallholders.

Oil Palm Waste

This chapter presents the design and development of an economically and technically feasible small-scale oil palm waste shredder to contribuite to oil palm waste management. Most available oil palm waste shredders are unaffordable due to high initial investment cost, large, heavy and unportable, which have been the drawbacks for small and medium enterprises to participate in the industry that relates with oil palm waste management. To address this issue, a low-cost and small-scale oil palm waste shredder were designed and produced. The central design concept deduced is to compromise acceptable efficiency with an affordable price by integrating all mandatory components of oil palm waste shredder into a comparatively small and portable support structure. The innovations made in the design are size reduction and adoption of double-shafts cutters with seven jaws technology. Preliminary calculations supported the design. The cutting force produced is up to 19.45kN with safety factor of 4.5. This design can handle other oil palm wastes as oil palm frond is harder than other oil palm wastes.

ABSTRACTSeveral alternative waste management innovations from oil palm mills with a capacity of 30 tons / year have been evaluated. These waste innovations are based on the most optimal renewable energy yield produced by oil palm mills, ie biogas, compost and pellets. The evaluation stage begins by collecting data from the operations of the common palm oil factories that is used as the data base-line. Furthermore, preliminary data is compared with the data of waste management innovation which is grouped into 3 (three) activities: (1) compost production from empty bunches, (2) biogas production from liquid waste treatment and (3) pellet production. The comparative results state that the plant's ability to process 1 ton of fresh fruit bunches can produce alternative renewable energy products either 207 kg of compost or 125 kWh of electricity or 125 kg pellets. This paper aims to evaluate the performance of palm oil mills in renewable energy production that is the most optimal in generating the largest profit margin. The results showed that based on the maximum profit potential obtained from each process of waste management, the percentage of the processed waste is about 19.8; 45.5 and 34.6% for the respective compost, biogas and pellet production. The processed waste will earn profit from renewable energy products of compost, biogas and pellet of as many as 6.1; 31.3 and 54.47 US$ / ton respectively. The overall waste treatment requires operating cost of 2.34 US $/ton and will result in a total profit of 91.89 US $ / ton.Keywords: waste, palm oil mill, renewable energy, performance evaluationABSTRAKBeberapa alternatif inovasi pengelolaan limbah dari pabrik kelapa sawit dengan kapasitas 30 ton/tahun telah dievaluasi. Alternatif inovasi limbah ini didasarkan pada hasil akhir energi terbarukan yang paling optimal yang dihasilkan oleh pabrik kelapa sawit, yakni berupa biogas, kompos dan pelet. Tahapan evaluasi diawali dengan mengumpulkan data kegiatan operasional pabrik kelapa sawit yang dijadikan sebagai data base line. Selanjutnya data awal tersebut dikomparasi dengan data inovasi pengelolaan limbah yang terbagi dalam kegiatan: (1) produksi kompos dari tandan kosong, (2) produksi biogas dari pengolahan limbah cair dan (3) produksi pellet. Hasil komparasi menyatakan bahwa kemampuan pabrik dalam mengolah 1 ton tandan buah segar dapat menghasilkan beberapa alternatif produk energi terbarukan yakni 207 kg kompos atau 125 kwh listrik atau 125 kg pellet. Tulisan ini bertujuan untuk membandingkan produktifitas inovasi produksi energi terbarukan yang paling optimal dalam menghasilkan margin keuntungan yang paling besar. Hasil penelitian menyatakan bahwa berdasarkan pada potensi keuntungan maksimal yang diperoleh dari masing masih proses pengelolaan limbah maka prosentase limbah yang diolah adalah dengan prosentase 19,8%; 45,5% dan 34,6%. Prosesntase limbah yang diolah tersebut akan menghasilkan produk energi terbarukan berupa kompos, biogas dan pellet dengan nilai keuntungan sebesar 6,1; 31,3 dan 54,47 US$/ton. Keseluruhan pengolahan limbah membutuhkan biaya operasional sebesar 2,34 US$ dan akan menghasilkan total keuntungan sebesar 91.89 US$/ton.Kata kunci : limbah, pabrik kelapa sawit, energi terbarukan, evaluasi kinerja

Agro-waste management generates worries to most developing countries and the menace needs to be curbed to reduce pollution. This study investigated the Proximate and Physicochemical composition of Oil Palm Empty fruit bunch. Samples collected were oven dried, grinded and analytical methods were carried out adopting AOAC 2005 (Association of official Analytical Chemists) test methods. The proximate analysis of the EFB revealed it to be a poor source of lipid (3.75 ± 0.01) but with a high fibre content (67.0 ± 1.19). The results showed concentrations of ash (6.87 ± 0.11), carbohydrate (12.3 ± 0.95), moisture (5.13 ± 0.24) and protein (4.87 ± 0.01). The physicochemical characteristics of oil palm empty fruit bunch is reported that pH had mean of 5.81±0.22, while temperature, total suspended solid, electrical conductivity, total dissolved solid, salinity, nitrate and sulphate had mean of 28.14 ± 0.02, 5.09 ± 0.02, 53.15 ± 0.03, 26.61 ± 0.015, 19.97±0.03, 14.65 ± 0.05, and 4.94 ± 0.02 respectively. More so, phosphate had mean of 17.55 ± 0.04, while ammonia, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, magnesium and calcium had mean of 0.04 ± 0.01, 2.86 ± 0.01, 1.58 ± 0.02, 2.55 ± 0.02, 1.05 ± 0.01 and 3.77 ± 0.01 respectively. The Proximate and Physicochemical composition of the Oil Palm Empty Fruit Bunch in this study demonstrates the efficiency of utilizing and application of this byproduct in various processes to help combat waste management issues in the environment.
