The purpose of this study is to analyse the incidence and the characteristics of anemia in NPC patients in a secondary referral hospital, Lombok, Indonesia. This research was carried out by analytic descriptive study using medical record data from secondary referral hospitals, Lombok, Indonesia. The data were obtained between April 2017 to March 2018. Nasopharyngeal cancer was established through physical examination, imaging, and histopathological examination. The stage of disease was defined according to AJCC 2017. Anemia was defined as Haemoglobin level less than 11 g/dl and the severity level according to WHO criteria. Classification of anemia based on MCV and MCHC are divided into normocytic, microcytic and macrocytic as well as normochromic, hypochromic, and hyperchromic according to the criteria of Chinese Clinical Oncology guideline 2012. There were 40 cases of patient with anemia who fulfil the study criteria, which consist of 30 male and 10 female, with the ratio 3: 1. According to the age, patients were distributed from 13 to 67 years old with the mean age for males was 46 (SD± 11.04) years old while the mean age for female was 50,9 (SD± 12,37) years old. Patients were found in stage II-IV, however, most of them were stage IV (68.75%). There were 87.5% of patients with anemia in different severity levels. However, the highest number was found in mild anemia level (57.5%). Based on the erythrocyte index, the majority types of anemia were hypochromic microcytic and normocytic normochromic (39,3%). The incidence of anemia in a patient with nasopharyngeal carcinoma at secondary referral hospitals in Lombok was 87,5%. Most of them were mild and hypochromic microcytic as well as normocytic normochromic type.Since the anemia and nasopharyngeal cancer (NPC) are a major problem in Indonesia and anemia has become one of the prognostic factors for the treatment of NPC, it is important to analyse the incidence and its characteristics in NPC patients especially in rural areas in Indonesia, such as Lombok.

In this case a proportional regulator with Kp gain is used. The stability of the basket is eliminated by the control circuit by applying a balancing torque that allows the basket to stabilize during movement. For the control system a feedback control circuit is provided. The regulator controls the equalization torque to keep the basket in a horizontal position during arm rotation.

This study aimed to examine the effect of application of Rhizobium and AMF bio-fertilizers on growth and yield of two soybean varieties under two treatments of plant spacing in vertisol ricefield during the dry season 2009 following rice crop without tillage. The experiment was arranged in a Randomized Block Design, with three blocks (replications) and three treatment factors, namely soybean varieties (V1= Anjasmoro; V2= Wilis), plant spacing (30x20 and 25x25 cm), and types of fertilizers (F1= without fertilizer; F2= Rhizobium application; F3= NPK only; F5= Rhizobium + AMF). Results indicated that application of both bio-fertilizers (Rhizobium and AMF) significantly increased soybean yield components, including grain yield, weight of 100 grains, grain number and total biomass per clump, compared with fertilization only with NPK or no fertilizers. There was no significant effect of plant spacing, but both varieties showed differences in plant height, grain yield, harvest index, and weight of 100 grains. However, there were interaction effects especially between variety and fertilization on plant dry weight, grain number and grain yield per clump, in which the highest grain yield was on soybean bio-fertilized with both Rhizobium and AMF, both in V1 and V2, but the average was higher in V1 (25.58 g/clump) than in V2 (15.03 g/clump).

(C2) and 4 levels of moss dosage, namely: 0 tons/ha (M0), 5 tons/ha (M1), 10 tons/ha (M2), and 15 tons/ha (M3). The results of the research revealed that moss had a significant role on improving soil physical carachteristic as well as nutrients uptake by corn and green beans. Soil aggregate stability improved from a less stable aggregate (40-50) without moss to rather stable (50-60) at level 5 - 10 tons/ha, and the aggregate was stable at dose of 15 tons/ha.

The average growth rate of corn growing with moss was 1.7 cm/day compared to 1.3 cm/day without moss. The average growth rate of green beans was 0.76 cm/day with moss and 0.6 cm/day without moss.
