Abstract

Land-use change from the forest to others will affect the soil’s physicochemical properties. The research was conducted to identify soil physicochemical properties affected by land-use change in Sungai Batang, the east-south part of Maninjau caldera. The research used a survey method from which soil was sampled at four different types of land use (forest, bushland, mixed garden, and paddy soil) at 0-30 cm depth with three replicates. The results show that the soil in Sungai Batang was still developing. It was indicated by coarse soil texture (clay loam to sandy clay loam). Land-use change from the forest to other uses has altered some soil physicochemical properties. It increased soil bulk density and decreased total soil porosity, permeability rate, SOM content, and  total-N. However, there was an increase in  soil characteristics, especially soil P-availability, CEC, Ca-  and Na-exchangeable . While the soil pH  (H2O), K-and Mg-exchangeable stayed the same. In general, land use changed from forest to other use, mostly farming land degraded physicochemical characteristics of the soil derived from volcanic materials in Sungai Batang. That was mainly due to the decrease in SOM content.

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

The customary village is one of the attractions in Sijunjung district, located in Kenagarian Sijunjung, Jorong Tanah Bato, and Padang Ranah. The resilience still sees the authenticity of the traditional village of the settlement pattern with the characteristic of a house that is gonjong. This house is called Rumah Gadang (adat house). Gadang houses are generally built on the edge of the road, with oval roofs and walls with traditionally carved values. Another attraction of the big house can be seen from the yard planted with various types of croton. Croton functioned as a fence or boundary between the house and other houses. The diversity of leaf and flower colors from croton can soothe the eyes of visitors or tourists. Most croton big fence needs to be rejuvenated (replanting), because many have died, growing lush and old age. The community needs guidance and skills to be able to multiply, fertilize, and prune. This activity aims to provide information on croton diversity and its techniques for propagating, fertilizing, and pruning croton plants. This activity uses counseling methods in the form of lectures, group discussions, and demonstrations. The activity results show that the people in the Tanah Bato and Koto Ranah traditional villages have been motivated to diversify croton as a big fence. This activity concludes that the community has known croton diversity and can multiply croton cuttings that can be used as propagation material.

Abstract

Arbuscular mycorrhizal fungi are a group of fungi that can be symbiotic with many types of plants. Soil factors and plant species, affect the diversity of arbuscular mycorrhizal fungi. Likewise, differences in location and rhizosphere cause differences in the diversity of species and populations of AMF. In addition, not all AMF have the same morphological and physiological characteristics, therefore it is very important to know their identity. Coffee is a plant that has economic value and the potential for symbiosis with AMF. This study aimed to identify AMF in the rhizosphere of four varieties of Solok Radjo coffee plants in the Aia Cold area of ​​the Gumanti Valley, Solok, West Sumatra. Meanwhile, the stages of this research include: collecting and collecting data in the field, determining the location of the soil sample, analyzing soil properties in the laboratory, isolating AMF spores, and identifying AMF spores morphologically. The results showed that the diversity of AMF spores was found in 3 genera, namely Glomus sp., Acaulospora sp., and Gigaspora sp. The Kartika coffee variety has a higher AMF spore population than Sigararutang, Andongsari and Gayo.

Abstract

Maninjau Village, including the tourist destination of Buya Hamka in Sungai Batang, is susceptible to natural disasters, such as landslides. It happens due to the sloping and high rainfall (> 3000 mm per year) area. The soil is prone to landslides if the sloping land is intensively cultivated for crop growth. This community engagement activity socialised and practised alley cropping techniques to manage farming in the sloping area. This method for introducing the alley cropping technique was through presentation and discussion as well as practice in the field with a farming group “Sehati”, a member of KPGH (Hamka generation youth community), and community leaders of the Nagari Sungai Batang in November 2021. A farmer cultivating red onion adopted the alley cropping method for the farm having a 19o39’ (36%) slope level with an alley width was 5 m. Gliricidia sepium and Tithonia diversifolia, known as green manure crops, were placed perpendicular to the slope of the alley fence. Gliricidia was planted every 5 m, and Tithonia between the Gliricidia at a 0.2 m distance in the alley fence.

Abstract

Desa Matotonan di Pulau Siberut Kabupaten Kepulauan Mentawai merupakan wilayah yang tergolong Komunitas Adat Terpencil (KAT). Masalah infrastruktur menjadi fenomena sendiri dalam masyarakat di desa tersebut. Tradisi hidup secara nomaden membuat masyarakat berada pada posisi yang tertinggal, homogen, terpencar dan geografis yang sulit dijangkau. Terkait dengan hal tersebut penelitian ini membahas tentang budaya yang berkembang dalam masyarakat Desa Matotonan beserta cara mereka bertahan hidup. Pendekatan yang digunakan dalam penelitian ini yakni multidimensional approach yaitu dengan menggunakan teori-teori ilmu sosial lainnya seperti sejarah antropologi, politik dan sosiologi (Kartodirdjo,1993). Hasil penelitian menunjukkan bahwa secara ekonomi, kehidupan mereka sangat orisinil dengan mata pencaharian berburu, bercocok tanam (sagu) dan mereka tinggal di huma. Makanan utama adalah sagu, ubi dan pisang. Ekonomi mereka sangat tergantung kepada alam dan terbatas. Untuk meningkatkan taraf hidup, mereka mencari jalan lain, terutama merantau meninggalkan Matotonan. Dalam kondisi ekonomi yang tidak jelas, anak-anak Matotonan pergi meninggalkan desa mereka yang nyaman di pedalaman Siberut untuk pergi sekolah. Kekurangan biaya dan ketidakpastian masa depan mereka hadapi untuk sebuah asa yang lebih baik.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.
