The increasing risk of lead poisoning such as neuro-behavioral disorders and neurological damage; hypertension, brain and kidney damage; DNA and antioxidant defense system cell damage in developing countries due to the increase in lead contaminated environment. This research was aimed to investigate the effects of prolonged lead on protein levels in the Marsilea crenata plant. The plants have been used for generation by local farmers as a daily source of vegetables during crop growing season. The plants are also known as an exotic cuisine known as Semanggi Surabaya. Marsilea crenata were grown inside a glasshouse using a modified Hoagland solution in different levels of Pb. The growth, Pb content, and total protein content were then measured for eight weeks during exposure. The result has shown that the root of Marsilea crenata has the capability to absorb lead and translocate them inside its shoots and leaves, with the biggest amount were translocated to the younger leaves during one week of exposure and was then accumulated in the old leaves after longer exposures. Total protein content was higher on younger leaves than in older leaves, followed by shoot and then the root. The result has shown that with deep knowledge of Marsilea crenata it is possible of using it as a phytoremediator or as a source of food since the total protein was translocated on the edible part. Still, awareness is still needed since the plant may contain high levels of Pb with the existence of stress symptoms. It should be avoided to reduce the risk of lead poisoning. Keywords: Lead, Marsilea crenata, growth, protein

Serealia such as rice, wheat, and maize are very important world food demands, and rice was highest on the nutrional protein status with respect to amino acid composition. Rice (Oryza sativa) has been an important primary cereal for generations that supply around 90% of carbohydrate needs in Indonesia, that every effort to be made in acquiring the fullfillment demand. The research was aimed to investigate the tolerance of two rice varieties Towuti and Ciherang grown on fertile and arid soil on different salinity. Healthy and homogenous three weeks old seedlings were grown in a glasshouse on 0, 50mM, 100mM, 200mM, and 300mM of NaCl on plastic pots with two different soil, under a randomized design and five replicated five times. The growth in terms of leaf area and surface electrical potential difference were observed on a weekly basis for four weeks after the plants had been exposed. The result showed that leaf area and the electrical PD of both rice varieties were significantly reduced under fertile and arid soil under 200mM of NaCl and 300mmM of salinity. It is implied that the photosynthetic process was significantly affected by salinity and was concluded that both varieties were sensitive to salinity at 200mM of NaCl. There was possibility that the protein content was involved on the osmotic change on the salinity process, element supplements were needed, but there is a need for less expensive methods.

The public awareness of environmental management and responsibility for production and consumption of food has increased, leading our collaborators in society to process food waste into organic fertilizer. Food waste management, especially kitchen waste, is a major focus in developing countries due to urban development and an equal attentiveness to environmental sustainability. Turning kitchen waste into organic fertilizer is a solution that is simple, cost-effective, eco-friendly and can be further enhanced by the addition of local microorganisms (MOL). However, the process of producing MOL-enhanced organic fertilizer is still not widely known. In this paper, the organic fertilizer was produced by the decomposition of kitchen waste enhanced by MOL. A non-MOL-enhanced fertilizer was also procured for control. Both of the obtained fertilizers were assessed for parameters such as pH, C:N ratio, and other organic content. The results proved that MOL-enhanced organic fertilizer is more effective than organic fertilizer made by natural decomposition alone.

The yard can provide great benefits for the community, because it can be planted with vegetables, fruits and spices such as turmeric, lemongrass, etc. The yard can also be used as a source of animal protein and an additional source of family income. Quail farming is an alternative for producing eggs which is quite productive in addition to laying hens and ducks. The advantages of quail cultivation are having a small body size and weighing about 130 grams, a short life cycle, high egg productivity (in the peak period of daily egg production it can produce about 90% of the total population in the cage), low feed intake (about 20 grams/quail/day), easy to cultivate and does not require a high investment. Quail can give results in the form of daily egg production and/or meat from rejected quail (quail that have stopped laying eggs or egg productivity that begins to decline after about 8 months of age). Quail cultivation from the yard of the house can be used to maintain approximately 25 quails. Based on these advantages, quail cultivation in the yard can provide family income and increase nutrition. Keywords: quail, yard, nutritional, income

The effective use of waste biomass is an important factor for sustainability and global energy consciousness. Unsurprisingly, tree wastes such as leaves, petiole and branch are plentiful during trimming or autumn season which offer an economical source of biomass. The objective of this study was to probe the mechanical and thermal characteristics of briquettes created from tree waste of langsat, guava and rambutan tree. Collected tree wastes (leaves, petiole and branches) were chopped, mixed and then carbonized at 400-600 °C using a Charcoal Retort tube system. The briquettes were molded manually using a Hydraulically Briquetting Machine at pressures of 20 and 50 N/cm2 for half an hour to 3 hours with regards on the type, density and fragments of the tree. Two system and machine were designed and fabricated by Biophysics Lab, Dept. of Physics, Faculty of Mathematics and Natural Sciences, Universitas Jember. Results indicated that briquettes made from tree waste of langsat, guava and rambutan have signs of mechanical and thermal properties which can be used as briquettes for various industrial uses.Keywords: Sustainability, Alternate fuel, Tree waste, Biomass, Briquette

CT Scan merupakan alat pencitraan sinar-X yang dipadukan dengan komputer pengolah data sehingga mampu menghasilkan gambar potongan melintang tubuh dan memiliki dosis relatif lebih tinggi, karena berasal dari radiasi primer dan radiasi hambur dari setiap slice. Dosis yang dihasilkan dipengaruhi oleh parameter scan yaitu faktor eksposi (tegangan tabung, arus- waktu rotasi) dan ketebalan irisan. Kuantitas dosis pada pemeriksaan CT Scan digunakan metode Computed Tomography Dose Index (CTDI). Penelitian ini dilakukan untuk mengatahui efek variasi parameter scan terhadap CTDI dan kualitas citra dengan menggunakan phantom. Hasil data yang diperoleh menunjukkan bahwa pada variasi 200 mAs, 120 kV dan 5 mm menghasilkan CTDIvol dan CNR optimum dengan nilai masing-masing 25.8 mGy dan 3.51. Hal ini disebabkan adanya keseimbangan nilai antara faktor eksposi yang tidak memiliki rentang yang terlalu jauh sehingga menghasilkan energi dan kuantitas sinar X yang seimbang dan ketebalan irisan tidak menghasilkan noise tinggi sehingga objek dalam phantom tetap dapat terlihat lebih baik. Kata Kunci: CT Scan, CTDI, CTDIvol, LCR, CNR.
