Abstract

The majority of Lambung Bukik Village people, Pauh Subdistrict, Padang City, make a living from farming horticultural crops, secondary crops, forest plants (Sungkai and gaharu) and raising cattle and chickens. The Sungkai Permai Farmer Group has a 2-5-year-old gaharu tree, the seeds obtained through the Elok Nagari CSR activities of PT Semen Padang. Currently, the agarwood tree has good potential through the inoculation of fungal pathogens on the agarwood tree to form economically valuable sapwood and the use of its leaves as a health drink. This activity aims to: 1). the community knows how to cultivate agarwood plants, know its benefits, and know-how to process parts of the agarwood tree, such as sapwood and leaves, into raw materials for tea drinks, 2). provide special skills for farmer groups members so that they are expected to be used as independent businesses; 3). They empower the community in utilizing empty land through the cropping pattern of aloes agroforestry with plantation crops, 4). as a form of community activity from Andalas University, especially the Faculty of Agriculture. This activity was carried out in the Sungkai Permai Farmer Group, Lambung Bukik Village, Padang City. The Sungkai Permai farmer group has acquired knowledge about gaharu cultivation and tea use through participatory methods and training in the form of demonstrations and demonstration plots by planting approximately 150 gaharu seeds as raw material for tea through an agroforestry pattern. The Sungkai Permai farmer group has acquired knowledge of using the part of gaharu to become aloe tea as a drink and health medicine from the leaves and sap of aloes. The Sungkai Permai farmer group can manage raw materials for gaharu leaves and sap derived from gaharu trees around farmers' land in Limau Manis sub-district, or other areas. They can be a productive business opportunity as tea and medicine in health drinks to improve the community's economy.

Abstract

Potatoes have the potential to be developed as a source of carbohydrates in supporting food diversification programs. Reduced potatoes production has resulted from a decrease in the land area for potato cultivation. The effort that can be made to increase land productivity is through multiple cropping systems such as intercropping, intermittent intercropping, streak planting, annual intercropping, and agroforestry. It is necessary to use idle land under plantation stands that have not been optimized, in increasing productivity and efficiency of agricultural production systems. This study aims to get the varieties that have the best growth and yields planted under immature coffee stands. This research applies a Single Factorial Experiment in Completely Random Design, where the factor is four levels of potato varieties, Granola (V1), Bliss (V2), Kentang Merah (V3) and Batang Hitam (V4). Observations made include plant height, number of leaves, leaf length, leaf width, tuber length, tuber diameter, weight per tuber, number of tubers/plat, and total tuber by grade tubers (Small, Medium, Large, Very large). Based on the analysis variance of each observation variable shows, there is an effect of the variable observation except the width of the leaves. Granola provides the best response to the growth and yield of potato plants

Abstract

Jamblang merupakan salah satu buah lokal Indonesia yang keberadaannya sudah jarang ditemukan. Jamblang dikenal oleh masyarakat Sumatera Barat khususnya Kota Padang sebagai jambu kaliang. Polen merupakan organ generative jantan dari tanaman yang berfungsi sebagai sarana utama pengalir gen pada persilangan spesies. Fertilitas adalah kemampuan polen atau bakal buah untuk tumbuh normal membentuk benih. Sedangkan sterilitas adalah kegagalan proses pembuahan karena ketidakmampuan pollen atau bakal buah untuk membentuk biji. Viabilitas polen merupakan persentasi polen yang akan menyelesaikan perkecambahan dan membentuk tabung sari (pollen tube). Penelitian ini bertujuan untuk mengatahui persentase polen tanaman jamblang yang fertile dan viable yang berguna bagi kegiatan pemuliaan tanaman. Pelaksanaan penelitian dilakukan dengan menggunakan metode pewrnaan dengan larutan bromothymol blue untuk mengamati fertilitas polen, dan pengujian vibilitas polen dengan metode Brewbaker dan Kwack (1964). Berdasarkan hasil pengamatan diketahui bahwa terdapat polen yang fertile pada semua genotype tanaman, akan tetapi tidak ada satupun polen yang mampu untuk berkecambah secara in vitro.

Abstract

Nagari Campago is located in Limakoto Subdistrict, Kampung Dalam, Padang Pariaman Regency. The area has great potential in agriculture, because there is a large area of wetland agriculture for white rice cultivation and dry land for chili plants and other seasonal crops. However, the reality that happened to Nagari Campago was that several times the harvest period, farmers experienced pests and diseases that resulted in crop failure. Farmers have limited information on red rice cultivation. The purpose of this activity is for Nagari Campago farmers to gain knowledge and understanding about brown rice, farmers can recognize and be able to make vegetable pesticides that can be used to control plant pests and diseases, thereby reducing maintenance costs. This activity was carried out in Nagari Campago, Limokoto Subdistrict, Kampung Dalam, Padang Pariaman Regency, West Sumatra Province. The method used is lecture, demonstration, discussion, monitoring. Socialization of the benefits of brown rice and demonstration training on the manufacture of vegetable pesticides to partners of the “Bukik Caliak Indah” farmer group. The result of the implementation of the activity is that the community is very interested in the cultivation of organic red rice and chili. The community is able to make their own botanical pesticides to control plant pests and diseases. From the results of the activity, it can be concluded that farmers are aware of environmentally friendly cultivation, and alternative sources of food crops.
