Title: Optimizing the Role of Assistance Student of Upsus Pajale Programs to Accelerate the Introduction of Cultivation Technology Jajar Legowo Super in Sijunjung RegencyThe Faculty of Agriculture of Andalas University is one of the government's partners in the successful implementation of Rice, Corn and Soybean (Upsus) Program at special province of West Sumatra. The implementation of Upsus Pajale in West Sumatra was found in eight districts and cities on 2017, one of which was Sijunjung Regency. Students and alumni participated as a companion in the implementation of several Upsus Pajale programs.Â In contrast to the implementation of Upsus Pajale in 2015 and 2016, in 2017, there were activities in applying technology in the work area of the accompanying students. The technology introduced by the field assistant lecturer together with the accompanying students, is the cultivation of Jajar Legowo super. The application of this technology was implemented in three sub-districts in Sijunjung Regency, namely Sijunjung, Tanjung Gadang and Kamang Baru. The activity was carried out in the form of a demonstration plot on the partner farmer's group's land. The technology of jajar legowo super has been successfully introduced to partner farmer groups, which is marked by increased production. The results showed that there was an increase in rice productivity using the Jajar Legowo Super method up to 4.6 tons / ha to 5.2 tons / ha than the conventional method of only 1.7-2 tons / ha.Â

The propagation plants coffee is carried out in generative manner and needs be optimized with treating gibberellin hormone and water temperature in germination stage of coffee seeds. This research aimed to know the effects of changes in the physical condition of coffee seeds with concentration of gibberellin hormone (GA3) and different water temperatures. This research conducted at the Seed Technology Laboratory Faculty Agiculture, Andalas University from July to September 2020. The method used was Randomized Complete Design with 3 replications. The parameters observed were seed weight early (g), seed weight after treatment (g), seed moisture content early (%), moisture content seed after treatment (%) and membrane leakage (Î¼mhos). Results showed that 200 ppm of gibberellin hormone concentration can increase weight of seed after treatment with 4.28 g. The best seed moisture content was at 90Â°C water immersion temperature with 48.28%.

The oil palm cultivated in the replanting area does not grow optimally because it was mostly attacked by rhinoceros beetle (Oryctes rhinoceros L.). The percentage of hornet beetle attacks is relatively high, at 80% in plants aged three years and 100% at 1-1.5 years. It was known that the residual waste replanting is the cause of the high population of horn beetles because the decayed palm oil stems become a suitable habitat for the development of these pests. To overcome the problems faced by partners, Integrated Pest Management (IPM) was applied. IPM components to be applied are cultural control, mechanical, and semiochemical control with pheromones. Community service was carried out using counseling methods, training, demonstration plots, providing equipment and machinery, as well as monitoring and evaluation. IPM technology assemblies that have been applied can reduce the attack rate of rhinoceros beetle from 86.68% to 79.60%. Until now, IPM equipment is still installed and operated by partner farmer groups. At the end of the activity, the partner farmer groups can apply IPM independently in their respective fields. Sustainable IPM applications, covering large-scale land, involving all palm oil business actors will increase the success of the method in the future.

Suatu daerah dikatakan endemik apabila terdapat laporan serangan OPT tertentu dalam skala besar. Daerah endemik serangan hama kelapa sawit dapat menjadi pedoman dalam mempelajari tingkat serangan hama di daerah tertentu. Ketinggian serangan hama pada daerah tertentu dapat menjadi acuan dalam menentukan teknik pengendalian yang tepat. Penelitian ini bertujuan untuk mengetahui jenis hama yang menyerang tanaman kelapa sawit di daerah endemik Kabupaten Dharmasraya. Metode yang digunakan adalah purposive random sampling. Sedangkan untuk pengambilan sampel dilakukan dengan koleksi langsung menggunakan tangan. Hasil penelitian ini didapatkan sebanyak 353 individu serangga dari 4 ordo, 9 famili dan 14 spesies. Jumlah individu tertinggi berasal dari Coptotermes sp sedangkan yang terendah spesies Setora nitens. Berdasarkan hasil penelitian dapat disimpulkan bahwa keanekaragaman serangga endemik kelapa sawit menyerang sangat tinggi dengan total spesies yang ditemukan sebanyak 14 spesies.

West Sumatra is one producing coffee area in Indonesia a significant contribution to economy in Indonesian, because production coffee in West Sumatra unstable, it is necessary to expand the area. The propagation plants coffee is carried out in generative manner and needs be optimized with treating gibberellin hormone and water temperature to germination stage of coffee seeds.This research was conducted at the Seed Technology Laboratory of the Faculty of Agriculture, Andalas University from May to August 2021. The parameters observed were initial seed weight (g), seed weight after treatment (g), initial seed moisture content (%), seed moisture content after treatment (%). The results showed that the observation of initial seed weight and initial seed moisture content showed no significant effect. While the data had a significant effect on the observation of seed weight after treatment with the concentration of gibberellin hormone and seed moisture content after treatment in the treatment of water types, where the observation of seed weight after the highest treatment was in the treatment of gibberellin hormone concentration of 400 ppm with aquadest (G4J1) of 4.23 g and on the observation of the water content of the seeds after the highest treatment, namely the treatment with the concentration of the hormone gibberellin 300 ppm with aquadest (G3J1), which is 46.32%. Key words: Seed Weight, Moisture Content, Aquadest
