Abstract

This study aims to determine the effect of satisfaction and work motivation on the performance of honorary teachers in high school 4 kerinci. The analytical tool used is multiple linear regression with the help of SPSS statistical sofware version 20. Techniques in sampling in this research was done with full sampling technique, as many as 37 respondents. Data collecting technique using questionnaire and literature. The hypothesis of this research is that there is a significant influence berween work satisfaction and motivation on the performance of honorary teachers in high school 4 kerinci. The results of the study show that the satisfaction variabel has a significant effect on honorary teacher performance with the prove t arithmetic > t table (4,728 > 2,03224) or sig < a (0,000 < 0,05) and work motivation variables have a significant effect on the performance of honorary teachers in high school 4 kerinci with proven t arithmetic > t table(3,056 > 2,03224) atau sig < a (0,004 < 0,05). The results of the F test indicate that the variables of satisfaction and motivation of work simultaneously influence the performance of honorary teachers in high school 4 kerinci with proven F arithmetic > F table (16,051 > 3,28) or sig < a (0,000 < 0,05). The amount of influence of satisfaction and work motivation on the performance of honorary teachers in high school 4 kerinci is 48,6% while the remaining 51,4% are explained by other causal factors not examined in this research.

Abstract

Fasting is one strategy to overcome the problem by giving the minimum possible amount of feed but the growth of the fish is not hampered. Fasting also means feed with a predetermined time interval in the hope that the fish can experience an increase in appetite after the fish are fasted. This study aims to determine the fisting effect of tilapia and feed efficiency et growth which fasting is the best to do. The research method used a simple completely randomized design with four treatments and two repetitions each, namely feed without fasting (treatment A), one day of fasting one day of feed (treatment B), one day fasting two days of feed (treatment C) and one day of fasting and three days of feed (treatment D). Fish were to eating three times a day at 08.00, 12.00, 17.00 at satiation. Fish seeds were given pellet feed as much as 3% of body weight. The results of analysis of variance test showed that fish feeding had no significant effect (P<0.05) at growth in weight and length and feed efficiency but significantly (P>0.05) at survival rate. The results showed that the best weight and length growth values in tilapia were found in treatment D with an average weight growth value of 12.20±0.22 gram, length 2.41±0.24 cm. The best feed efficiency was found in treatment B, which was 60.83±6.60% and the best survival was found in treatment A a with an average value of 86.67±0,00%.

Abstract

Retread tire dump trucks imported and local characterization has been performed as a basis for modeling the development of a formula dump truck tire retreading. Materials used include natural rubber SIR 20, Thermoplastic Elastomer (inserting ETP), carbon black, silica and fly ash. The test results showed that the addition of the ETP on natural rubber SIR 20 for retread tire dump trucks can increase the hardness of 3.03%, 3.87% tensile strength, tear strong 15.46%, 100% modulus with a value of 36.28%, the modulus 300% with a value of 27.71% and 52.46% abrasion value. Testing of mechanical properties in fresh condition after aging (aging) and after ozone exposure given PPHM 25 for 3x24 hours at a temperature of 40°C shows, the addition of ETP a positive effect on some mechanical properties. The test results showed the addition of SEM-EDS ETP can protect natural rubber from ozone attack. Fly ash is added to the compound of formula has a tendency to bind to one another, so that the process of making the formula developed an innovative mixing with coupling agent Si type of PEG 400 and 69.Keywords: natural rubber, ETP, carbon black, fly ash, dump truck tire compound.AbstrakVulkanisir ban luar dump truck impor dan lokal telah dilakukan karakterisasi sebagai dasar untuk membuat model pengembangan formula vulkanisir ban luar dump truck. Bahan yang digunakan antara lain karet alam SIR 20, Elastomer Termoplastik (inserting ETP), carbon black, silica dan fly ash. Hasil pengujian menunjukkan, penambahan ETP pada karet alam SIR 20 untuk vulkanisir ban luar dump truck dapat meningkatkan kekerasan 3,03%, kuat tarik 3,87%, kuat sobek 15,46%, modulus 100% dengan nilai 36,28%, modulus 300% dengan nilai 27,71% dan abrasi = 52,46%. Pengujian sifat mekanik pada kondisi segar setelah proses penuaan (aging) dan setelah diberi paparan ozon 25 pphm selama 3x24 jam pada suhu 40°C menunjukan, penambahan ETP memberikan efek positif pada beberapa sifat mekanik. Hasil pengujian SEM-EDS menunjukan penambahan ETP dapat melindungi karet alam dari serangan ozon. Fly ash yang ditambahkan pada formula kompon memiliki kecenderungan berikatan satu sama lain, sehingga pada proses pembuatan formula dikembangkan suatu inovasi pencampuran dengan coupling agent jenis PEG 400 dan Si 69.Kata Kunci : karet alam, ETP, carbon black, fly ash, kompon ban luar dump truck.

Abstract

Indonesia's financial development is also marked by the diversification of financial products, namely by the emergence of non-bank financing institutions that can be used as alternatives to meet the community's needs for the desired financing. The development of non-bank financial institutions that offer various forms of financing facilities will further expand the provision of alternative financing for the business world and the needs of the Indonesian people in the Indonesian economic system. This study aims to determine the determination of Islamic financing and the mechanism of sanctions for late payments at the Metro City FIF. This type of research is field research (field research). While the nature of this research is descriptive. The data sources used are primary and secondary data sources. Data was collected using interview and documentation techniques. The data from the findings are described descriptively and analyzed using inductive thinking. The results of this study indicate that the determination of Islamic financing in the Islamic system is not known as the interest system as an instrument to obtain profits for the company. Because basically sharia financing in conducting business transactions uses a sale and purchase contract or known as murabahah, which is a contract used to procure an item by confirming the purchase price to the buyer and the buyer pays it in installments at a higher price as profit. The Sharia FIF mechanism if the consumer is unable to pay the installments then the goods will be withdrawn and resold. So that the FIF Syariah does not pay attention and even tends to eliminate the risk aspects that will be encountered when the customer/consumer occurs in the event of a delay in payment
