Abstract

Land-use change from the forest into tea plantation in Solok Regency in 1983 has decreased the area of forests in Gunung Talang District. Clearing up the forest at the beginning for tea plantation could worsen the physical and chemical conditions of the soil. One of which is soil aggregate stability that is very dynamic and can influence other soil physical properties. This study was aimed to determine soil Aggregate Stability Index (ASI) at tea plantations. Soil samples was taken at a depth of 0-20 cm from five different slopes (0-8% (A), 8-15% (B), 15-25% (C), 25-45% (D), and> 45% (E)) and at two crop ages (10 and 35 years old). The results showed that the soil aggregate stability index at tea plantations ranged from stable to very stable. It tended to decrease by increasing slope percentage at each of crop age, Between the ages, it showed higher ASI at 35 years old crop age under relatively flat (0-8%) and very steep (>45%) areas.

Abstract

Tujuan dari penelitian ini adalah mengevaluasi kesesuaian lahan untuk pengembangan kakao rakyat yang berbasiskan konservasi tanah. Metode penelitian adalah metode suvai.  Contoh tanah diambil secara purposive random sampling di masing-masing satuan lahan. Contoh tanah utuh untuk analisis sifat fisika tanah. Sedangkan contoh tanah terganggu untuk analisis sifat kimia tanah.  Disamping itu, data iklim diambil dari kantor cabang dinas pertanian Pasaman. Data dari hasil survai tanah dan iklim disusun dengan sedemikian rupa kemudian di cocokan (matching) dengan kebutuhan dari syarat tumbuh dari tanaman kakao. Hasil dari mencocokan atara data lahan dengan syarat tumbuh dari tanaman kakao didapatkan tingkat kesesuaian lahan. Kelas kesesuaian lahan aktual  dilokasi penelitian nagari Sundatar Lubuk Sikaping Pasaman ini adalah termasuk kesesuaian marginal (S3) karena faktor pembatas curah hujan yang tinggi yakni 3251 mm/tahun dan kestersedian hara yang rendah. Disamping itu sebagai masukan perlu dilakukan penambahan bahan organik dan pupuk buatan. Pada lahan yang landai sampai agak curam penerapan kaedah konservasi dengan penanaman multistrata sangat perlu untuk mencegah erosi. Kesesuaian lahan potensialnya adalah S3. Key word: kakao, kesesuaian lahan, konservasi.

Abstract

ABSTRACT The purpose of this study was to identify the relationship between inseminator characteristics (internal and external) to the success of AI in Sawahlunto City. The objects of this research observation are all inseminators in Sawahlunto City. The data were analyzed with the simultaneous F test to see the effect of the variables simultaneously and the Partial T Test to see the effect of each variable. The results of the study found that the success of artificial insemination in Sawahlunto City was not very good, where an average S/C value of 3.04 was found. Internal characteristics (years of service, thoroughness, responsibility, technical ability in straw and thawing management, ability to understand the anatomy of the reproductive organs) and external (distance from home to work area, completeness of facilities and infrastructure, sanitation of equipment, communication of livestock reporting) have a significant relationship (P<0.05) on AI success, while internal (experience, training intensity) and external characteristics (IB postal conditions) did not have a significant relationship (P>0.05) to AI success in Sawahlunto City. From the results of this study it can be concluded that the characteristics of the inseminator (external and internal) influence the success of AI in Sawahlunto City. Keywords: Artificial Insemination (AI); Inseminator; Internal and Eksternal Characteristics

Abstract

Humans need fresh water for many functions, including cleaning, irrigating plants, drinking, cooking, industrial uses, and more. It cannot be denied that the excessive exploitation of the environment by humans is the cause of the current decline in water quality. This study aims to test water quality such as pH, conductivity, total dissolved solids, salinity, and turbidity. The research method uses quantitative methods. The research area was taken from 10 subdistricts around the Arau River Basin. The sample is measured using a predetermined measuring instrument. Based on the test results from all research areas, several parameters for testing water quality meet the standards of the 2010 Ministry of Health Regulations, such as the pH test except for the Indarung and Lubuk Begalung sub-districts. and East Padang. The Total Dissolved Solids test in all areas is in good water standard except for Koto Tangah. The salinity test for all areas met the requirements for water quality standards except for the West Padang sub-district and the Turbidity test showed that all areas had turbidity values > 5 NTUs..

Abstract

This study aimed to investigate the effect of mathematical-logical intelligence, visual-spatial intelligence, and learning motivation simultaneously toward student’s problem solving ability. The population in this study was the grade XI students in Gowa regency and the sample was 353 students. The sampel was drawn using proportional stratified random sampling. The instrument used to collect data was mathematical-logical intelligence test, visual-spatial intelligence test, problem solving ability test, and questionnaire of learning motivation. Multiple regression analysis were employed in this study. The result of this study showed that students have moderate mathematical-logical intelligence and visual-spatial intelligence, high learning motivation, and low problem solving ability. There was positive effect of mathematical-logical intelligence, visual-spatial intelligence, and learning motivation simultaneously toward student’s problem solving ability. It could be seen by regression coefficient R = 0,334. The coefficient of determination R2 = 0,111 implyed that mathematical-logical intelligence, visual-spatial intelligence, and learning motivation simultaneously contributed to 11,1% of student’s problem solving ability.

Abstract

This Classroom-Action Research aimed to improve students’ mathematical reasoning ability as integrated with TPACK. In this research, TPACK was implemented by examining teachers’ ability in designing Microsite during the teaching and learning process. The subjects of this research were students in the eleventh grade, XI IPA 1, SMAN 1 Sarjo, Pasangkayu. 2 cycles were conducted as the research steps, such as making plans, conducting the actions, conducting observations, and conducting several reflections. The instruments used in this research were the PBL-TPACK learning implementation sheet and mathematical reasoning ability test. The results of the study revealed that at the end of cycle 2, the average score of teachers and students’ activities was in the very good category with total scores of 89.67% and 88.02% respectively. Meanwhile, the average score of students' mathematical reasoning ability was 90, with the maximum total number of all students. Based on the results of the study, it can be concluded that students' mathematical reasoning ability increased through the implementation of integrated PBl TPACK.

Abstract

Mathematic literacy is important in children from an early age because mathematics plays a very important role in everyday life. Introducing mathematical concepts early, building strong numeracy skills and involving students in meaningful mathematical activities. The purpose of this service is to reinforce mathematical literacy through integrated matriculation of the environment for children in the Tamo Dhua environment. Matriculation activities were carried out for 5 days for children in the Tamo Dhua Environment consisting of grades I to VII to strengthen children's mathematical literacy by teaching mathematical concepts and linking them to examples of everyday life. The results of this service activity are that children's mathematical literacy has increased, children increasingly like mathematics and children are very enthusiastic about participating in the matriculation activities.
