Students’ Learning Strategies for Developing Speaking Ability

This study was done to study the learning strategies used by both low and high performance speaking students in developing their speaking skills as well as the differences between the learning strategies used by both groups of learners. The reason for conducting this research was the fact that the competency of many students in speaking English was still considered unsatisfactory in Banda Aceh. We postulated that one aspect involved in the process of developing speaking skills was the learning strategies used by the learners. In this study, the data was collected through field research by means of documents, questionnaires, and interviews. The result of this study indicated that high performance speaking students had better balance in using all kinds of learning strategies (memory, cognitive, compensatory, metacognitive, affective, and social) for enhancing their speaking skills; the same could not be found with low performance speaking students. Besides, the high performance students employed more learning strategies consciously and appropriately compared to the low performance students. Based on the research results, it is suggested that students should be trained to be more aware of their own speaking learning strategies. They should use appropriate language learning strategies more consciously, purposefully, and frequently to be more successful in developing their speaking skills.

Fish Biodiversity in Poigar River Estuary North Sulawesi

The purpose of this study was to determine the diversity and size variation of fish caught in the Poigar River Estuary. Sampling was carried out on tide and low tide in the New Moon and Full Moon phases using beach trawl. The catch gets 42 species, 2,726 individuals and weighs 11,355.5 g. The dominance index at low tide and water recedes 0.47 and 0.44 respectively. Diversity Index at high tide and low tide are 0.93 and 1.11 respectively. Found 10 important fish species in tide and 13 species at low tide, there are four species which are important fish both at low tide and high tide, namely Ambassis urotaenia, Ambassis intetrupta, Gazza minuta and Gerres filamentosus. The size distribution of fish from the juvenile phase to the adult phase is the Ambassis urotaenia with a distribution size of 4.2 cm to 9.0 cm and the Ambassis interupta 4.3 to 9.7 cm. Fish classified as only in the juvenile phase are Gazza minuta with a distribution size of 4.0 cm to 12.9 cm and Gerres filamentosus 6.3 cm to 8.6 cm.Kata kunci: Biodiversity, River Poigar, species, juvenile and adult.ABSTRAKTujuan penelitian ini adalah untuk mengetahui keanekaragaman dan variasi ukuran ikan yang tertangkap di Muara Sungai Poigar.

The Effectiveness of Warehouse Utilization at Soekarno-Hatta Internasional Airport

In order to improve the performance of cargo warehouse owned by PT JAS, layout redesigning is carried out. It is to facilitate the operator in storing, moving, and carrying cargo so that these activities can run quickly and systematically with relatively low cost. By using the method of Cube per Order Index (COI) that refers to the data of import cargo movement in 2010, it is found that the utilization of PT JAS warehouse at Soekarno-Hatta International airport can still be optimized up to a hundred percent from the current condition

Analisa Pengaruh Desain Gritcone terhadap Pola Patahan Gritcone pada Vertical Roller Mill dengan Simulasi Explicit Dynamic (LS-DYNA)

Polysius Vertical Roller Mill adalah coal mill yang digunakan PT Holcim Indonesia untuk menggiling batubara bituminous untuk bahan bakar rotary kiln. Dalam pengoperasiannya, salah satu komponen dari Vertical Roller Mill mengalami kegagalan aus yaitu gritcone. Penelitian ini dilakukan untuk menganalisa perseberan ketebalan dari komponen gritcone dengan disimulasikan secara dinamis eksplisit dan berdasarkan kondisi operasional. Ketebalan dinding dipetakan karena permukaan yang terkena abrasi terdapat patahan mikro di permukaannya. Penelitian dilakukan dengan variasi ketebalan 0.01 m, dan 0.02 m serta variasi desain gritcone dengan radius bawah sebesar 0.165 m, 0.215 m, 0.265 m, 0.315 m, dan 0.365 m. Hasil penelitian menunjukkan pengurangan ketebalan paling besar terjadi pada desain gritcone dengan radius 0.165 m dengan ketebalan 0.01 m dan 0.02 m, dengan pengurangan sebesar 1.423x10-5 m dan 2.45x10-5 m

Evaluasi Dampak Penerapan Automated Dispensing Machine terhadap Dispensing Error di Farmasi Rawat Jalan Instalasi Farmasi Rumah Sakit Bethesda Yogykarta

Dispensing error is not uncommon in the medication proccess. Otomatisation of outpatient pharmacy services decrease the incidence of dispensing error, as well as improving the efficiency of picking, packing and labeling process. Since August 2014 an automated dispensing machine was installed in outpatient pharmascy Bethesda Hospital Yogyakarta, integrated with electronic prescribing and hospital information system. The objective of the study was to evaluate the impact of automated dispensing machine on the dispensing error at outpatient pharmacy Services using before and after study method. The procentage of drugs deliver by automated dispensing machine at the third and sixth month of implementation was 46% and 59%. Failure mode and effeect analysis of dispensing process done before the implementation, and the integration with electronic prescription and hospital information system, as well as the development of smart pack is the key of successed. The average of medications picked after the implementation of automated dispensing machine was (37,915.33 ± 3,160.12), higher than before implementation (36,812.67 ± 2,890.81), but not significant. The average of dispensing error after implementation (15,67 ± 6,28) was reduced significantly (p<0,05) than before (50.33 ± 34.47). The most frequent type of dispensing error were wrong quantity dispensed, wrong drug dispensed and wrong strength dispensed. The implementation of automated dispensing machine significantly reduce the incidence of dispensing error. Further investigaation needed to know the incidence of dispesning error cause by the machine and manual and factors that influenced

PERTUMBUHAN AWAL TITI (Gmelina moluccana)

Titi or Gmelina moluccana is a type of the Lamiaceae family that grows in Maluku. Although this species is local, there is still very little information about its growth. This study aims to determine the growth of this species from planting in the field until the sixth year, environmental factors that affect its growth. Data collected in the form of plant height and diameter, air temperature, humidity, soil pH, soil moisture, sunlight intensity. Environmental factors are then related to plant height and diameter to determine environmental factors that affect the growth of these plants through multiple linear regression equations. Besides, the mean annual  increment and the current annual increment is also calculated to determine the cycle of this plant. Based on the results of research, Titi plants up to the sixth year have an men annual increment and the current annual increment is 0.99 meters/year and 1.46 meters for height and 1.62 cm/year and 2.50 cm for diameter. Until the sixth year this species has not entered the techniquecycle, while for woodworking purposes, this species can be harvested at the age of 24.5 years. Environmental factors that affect the growth of Titi are soil pH and soil moisture

DEVELOPMENT OF TITI PLANT (Gmelina moluccana) SIX YEARS AFTER PLANTING

Titi (Gmelina moluccana) is one of the native species that grow in Maluku. The information such as the growth and development of this species was still lacking. The purpose of this study was to determine the development of Titi plants at six years after planting. This research was studied lasted for six years and the measured data were plant height and diameter for six years. The method used is to analyze the development of the Titi plant based on the growth phase of the tree.  The results showed that Titi plants after six years of planting had been in the growth phase of saplings or young trees and this type was species that in catagory fast growing because it almost reaches its economic cycle. These plants can be used for forest cultivation and industrial raw materials
