Depletion of soils and climate change are currently reducing crop yields in West Africa. As a solution, soil improvement based on organic waste products is often considered. The experimental device used for this experiment is a File block with three repetitions which includes five treatments, namely T0: control plot, T1: treatment of bio-waste after one month of degradation, T2: treatment of bio-waste after three months of degradation, T3: NPK treatment drawn 15-15-15 (fertilizer for cotton), frequently used by populations in the fertilization of vegetable crops and T4: biofertilizer from the local market. The lettuce seedlings of the verdana variety (Lactuca sativa) from a nursery, were sown on the different treatments, then followed for 45 days. Biowaste samples at one month and three months of degradation, as well as soil samples taken in a depth of 0 to 20 cm, after the experiment were used for various laboratory analyzes. The results obtained indicate that the T2 treatment had a better carbon level (C = 2.04 g / kg) compared to the other treatments. Furthermore, the study revealed C / N ratios varying between 6.05 and 9.13 for treatments based on bio-waste compared to the control (C / N = 2). The lettuce yields obtained after the various applications of bio-waste have significantly improved compared to other treatments (control, biofertilizer and chemical fertilizer). Thus for T0 the yield obtained is 0.23T / ha against 1.39T / ha for T1, 0.57 T / ha for T2; 0.4 T / ha for T3 and 0.23 T / ha for T4. Compared to the technical data sheet for this variety of lettuce, the T1 treatment has a better yield compared to others.

Acetyl salicylic acid was synthesized by the method of microwave radiation, Acetyl chlorine and salicylic acid were used as raw materials, iodine was used as catalyst. The amounts of acetyl chloride, iodine and catalytic time of microwave were investigated on the yield of acetylsalicylic acid, the best test conditions were obtained by orthogonal experiments furthermore. In order to investigate the quality of the products, the products were then applied at the bud of soybean seed. The factors that affect the yield of acetyl salicylic acid are: acetyl chloride (A) >catalytic time of Microwave (C) >catalyst of iodine(B), the amount of salicylic acid is 2.7 g, the amount of acetyl chloride is 2.4 mL, and the amount of iodine is 0.4 g, The catalytic time of microwave is 50 s at 800 W. Under the above test conditions, the power of acetylsalicylic acid was obtained with the yield of 64.52 %, it is odorless and slightly sour.

Proboscis monkey (Nasalis larvatus) is one of the endemic species in Kalimantan. Nowadays, they are belonging to endangered species based on IUCN assessment. Blood examination is important for body health evaluation, especially in non-human primates where lived in a zoo, animal captive or rehabilitation center. The study was carried out to examine the hematology profile of female-juvenile proboscis monkey blood cells in Sahabat Bekantan Indonesia in Banjarmasin, South Kalimantan. Blood samples were collected from four female-juvenile probosci's monkey at Sahabat Bekantan Indonesia. The sample was examined for hematology and blood morphology profile. The hematology profile showed the mean of erythrocytes, the erythrocytes indices, the mean of leukocytes, the differential of leukocytes and the mean of platelets. The morphology of proboscis monkey blood cells was similar to other domestic animals, even though the shape and size were various. In conclusion, there was no blood cell abnormality and the hematology profile could be a clinical parameter for monitoring and evaluating female-juvenile proboscis monkey in the rehabilitation center.
