Abstract

This research was carried out in the research field of the Faculty of Agriculture, Asahan University with a height of 10 m above sea level, climate type C (oldeman). The study was conducted from January to March 2019. The research materials consisted of Bima Brebes variety of shallot seed tubers, dried chicken manure, Top G2 organic liquid fertilizer, Deltamethrin active ingredient (Decis 2.5 EC), fungicidal active ingredients Mankozed (Decis 2.5 EC) Dithane M-45 80 WP) and water. The research tools used were hoes, rakes, tripe machetes, torches, raffia ropes, knives, gauges, schalifers, calculators and other stationery, title boards, sample plant plates, bloated, and treatment boards. This research was arranged based on a factorial randomized block design (RBD) consisting of 2 treatment factors and 3 replications. The first factor is the application of POC top G2 fertilizer with 4 levels, namely: P0 = 0 cc / liter of water, P1 = 4 cc / liter of water, P2 = 8 cc / liter of water, P3 = 12 cc / liter of water. The second factor is the provision of cow manure with 3 levels, namely: A0 = 0 tons / ha, A1 = 5 tons / ha, A2 = 10 tons / ha. The results showed that the best application of top G2 POC fertilizer was obtained at a dose of 12 cc / liter of water / plot resulting in a plant height of 25.56 cm, a total tuber crop of 7.96 cloves, a crop production of 63.52 g, production per plot of 1.27 kg. The best application of cow manure is obtained at a dose of 10 kg / ha = 1 kg / plot resulting in a plant height of 27.39 cm. number of crop tubers 8.38 cloves, production per plant 62.21 g, production per plot 1.25 kg. The interaction between the application of top G2 POC fertilizer and chicken manure on the growth and production of shallot plants showed no significant effect on all parameters observed.

Abstract

This research was arranged based on Factorial Randomized Block Design with two treatmentfactors and three replications, the first factor was the giving of various types of organic fertilizer(P) consisting of 4 levels ie P0 (without treatment), P1 (bokashi cow dung), P2 ( bokashi legum) and the second fator is the application of urea (U) fertilizer consisting of 3 levels ie U0 (control), U1 (10 g / plot) and U2 (20 g / plot). The results of research that treatment of various types of organic fertilizer significantly affect the growth and yield of water spinach. The best treatment was obtained at treatment (P3) yielding 22,10 cm height, 25,33 pieces of leaves, yield per crop 39,29 g and yield per plot 3,87 kg. The treatment of urea fertilizer has an effect on the growth and yield of spinach water. The best treatment was obtained at a dose of 20 g / plot (U2) resulting in plant height of 22.42 cm, number of leaves of 23.42 pieces, production per plant 39.04 g and production per plot of 3.85 kg. Interaction treatment of various types of organic fertilizers and urea fertilizers did not show a significant effect on the growth and yield of water spinach.

Abstract

The research was conducted in the Tanjung Sari village, Sei Dadap, Asahan, North Sumatraprovince with a height of ± 17 m above sea level, tipy of climate C (oldeman). This study wasconducted in Mey to July 2017. The study design was a Randomized Block Design (RBD)Factorial consisting of 12 treatment combinations, each 4 levels application of Miracle Grofertilizer is: M0 = 0 g Miracle Gro/l water (control), M1 = 1 g Miracle Gro/l water, M2 = 2 g Miracle Gro/l water, M3 = 3 g Miracle Gro/l water and 3 levels of manure fertilizer is: K0 = 0 tons/ha (control), K1 = 15 tons/ha (4,5 kg/plot), K2 = 30 tons/ha (9 kg/plot). The results showed that giving Miracle Gro of concentration 3 g/l water (M3) on sweet corn can increase the growth of crop height age of 2, 4 and 6 Weeks After Planting (WAP); stem diameter ages 6 WAP; the number of leaf age 2, 4 and 6 WAP; weight of cob weighs per plot; weight of cob without any weight per plot. Giving manure fertilizer up to dose 30 tons/ha (K2) on sweet corn can increase the growth of crop height age of 2, 4 and 6 WAP; stem diameter ages 6 WAP; the number of leaf age 2, 4 and 6 WAP; weight of cob weighs per plot; weight of cob without any weight per plot. Interaction of giving Miracle Gro and manure fertilizer very significant effect on plant height, weight of cob weighs per plot; weight of cob without any weight per plot. The interaction is best obtained in treatment M3K2 (3 g Miracle Gro/l water and 30 tons/ha of manure fertilizer).

Abstract

Penelitian ini bertujuan menentukan hubungan antara dinamika kondisi oseanografi terhadap fluktuasi hasil tangkapan dan memetakan daerah penangkapan (DPI) ikan pelagis besar di perairan Teluk Bone. Studi mengenai dinamika kondisi oseanografi difokuskan pada sebaran suhu permukaan laut, konsentrasi klorofil-a, dan kedalaman perairan. Pengambilan data dimulai pada bulan April sampai dengan September 2017. Studi ini menggunakan dua jenis yaitu data primer mencakup jenis dan jumlah hasil tangkapan serta posisi penangkapan ikan. Data citra satelit oseanografi yang bersumber dari satelit Terra/MODIS dan AVISO/ETOPO2 sebagai data sekunder. Data yang diperoleh dianalisis dengan menggunakan Generalized Additive Models (GAMs) dan dipetakan dengan menggunakan teknik Sistem Informasi Geografis (SIG). Hasil studi menunjukkan bahwa terdapat hubungan yang kuat antara dinamika kondisi oseanografi dengan fluktuasi hasil tangkapan ikan pelagis besar di perairan Teluk Bone. Distribusi ikan cenderung terjadi pada area perairan dengan suhu permukaan laut berkisar antara 29 - 29,5 oC, dimana konsentrasi klorofil-a pada area tersebut pada nilai 0,2 - 0,4 mg/m-3, dan cenderung di daerah lepas pantai pada kedalaman perairan sekitar 500 - 1.000 m. Kata kunci: kondisi oseanografi, DPI, ikan pelagis besar, teluk bone.

Abstract

This study aimed to determine the internal and external factors that cause low learning achievement of fifth-grade students at SDN 1 Barejulat. Internal factors include intelligence, interests, talents, and motivation, while external factors include family, school, and community. This study uses a qualitative approach with a case study method. Data collection techniques were carried out through interviews, observations, and documentation studies.  Instrument using interview sheet. The data analysis technique used is data reduction, data presentation, conclusion, or verification. Test the validity of the data using extended observations, increasing persistence, source triangulation, technique triangulation, and time triangulation. The subjects of this study were fifth-grade students. The results of this study indicate that students who get low learning scores, are caused by the lack of intelligence, interests, talents, and motivations possessed by both of them. Besides that it is also influenced by the family environment, school environment, and environment. Low student motivation is due to students’ high sense of laziness in doing assignments and the lack of motivation given by parents. The family environment is very closely related to learning achievement. This is related to the lack of attention and warmth in the students' families themselves. Efforts made by teachers in improving the learning achievement of fifth-grade students at SDN 1 Barejulat are by creating a class atmosphere that is thick with the spirit to compete, and guiding students by holding additional lessons. In addition, the teacher also tries to communicate with the parents of these students so that they pay more attention to their children's learning activities.
