Abstract

This activity aims to make a disaster prone Nagari district base of the subdistrict of the regency of fifty cities, became the Nagari alert disaster, so the community Nagari the base is tough and standby if there is suddenly a flood disaster, so the impact is not too big. The lack of knowledge and public awareness of flood disaster and environmental concern, as a result of prioritizing economic interests, so that many communities do land clearing and reduced green open land in the base area. In fact, with the clearing of land that is not balanced with environmental conditions, then there is rain with great intensity, then the area becomes a region that is prone to flood disaster. It is proven two years in a row (2016 and 2017) flooding occurs that exceeds 1 meter so it has a big impact on all the facilities and infrastructure including agriculture and plantation owned by Nagari Pangkalan community. Some approach methods offered to support the realization of this dedication program are training and demonstration with the descriptions, among others: (1) Case studies, (2) practice/demonstration primarily in the study of Biopori, (3) Brains Storming/Community Ideas Gathering, (4) questions and answers between community and instructors or related governments, (5) lectures that contain core material and advanced activities plan that is a solution to the problems faced by the community. This activity is expected to be in accordance with the plan of activity and can be measured in order: (1) assisting the community in improving their knowledge and skills in utilizing biopolar as one of the efforts to overcome flooding, (2) assisting local governments in an effort to improve community knowledge and skills through the transfer of knowledge and skills so as to anticipate flood disaster and to remind the welfare of

Abstract

Indonesia menjadi negara nomor 2 penghasil sampah laut di dunia. Timbunan sampah plastik diperkirakan mencapai 24.500 ton per hari atau setara dengan 8,96 juta ton per tahun. Kurang lebih 9,8 miliar lembar kantong plastik digunakan masyarakat Indonesia setiap tahunnya. Dari jumlah itu, hampir 95 persen menjadi sampah. Kondisi ini sangat berbahaya, karena sampah plastik butuh ratusan tahun untuk terurai ke lingkungan. Berdasarkan data yang diperoleh dari Asosiasi Industri Plastik Indonesia (INAPLAS) dan Badan Pusat Statistik (BPS), sampah plastik di Indonesia mencapai 64 juta ton/ tahun dimana sebanyak 3,2 juta ton merupakan sampah plastik yang dibuang ke laut.Begitu juga di Kota Pariman yang sampah lautnya tersebar sepanjang pesisir pantai di kota pariaman. Tumpukan sampah yang ada akan hanyut terbawa ke laut. Jumlah limbah ini semakin lama semakin besar, dan hingga sekarang belum diketahui pasti dampak lingkungannya secara jangka panjang, selain dampak estetikanya yang sudah jelas merugikan, sehingga menambah volume sampah laut di kota pariaman dan provinsi sumatera barat. Metode untuk pemetaan titik kumpul adalah metode teknologi Sistem Informasi Geografis (SIG) dengan menggunakan pendekatan kuantitatif. Hasil penelitian menunjukkan 1) Terdapat 6 objek wisata sumber sampah atau sumber penghasil sampah, laut di kota pariaman. 2) Dominasi sampah yang ada di kota pariaman adalah sampah organik dengan presentase mencapai 79,705%, sedangkan anorganik mencapai 20,295%.

Abstract

Biomass is the total amount of living material on the surface of a tree and expressed in units of tons of dry weight per unit area (Brown (1997) in Sutaryo (2009)). The area in the Bompon watershed has a high vegetation density which has a role as a source of daily, monthly, seasonal and annual income for the community. The purpose of this study was to determine the total aboveground biomass in a tree and its effect on avalanches in the Bompon watershed. The method used in this study is the calculation of biomass is a non-harvest sampling method. The calculated biomass of trees is biomass on the surface covering parts of the tree such as: branch branches, and leaves. The allometric approach uses the biomass equation that has been developed before, so that in this activity only the diameter (dbh) and tree height results of the inventory (Land Range Research Group, 2016) are needed. The results showed that in the downstream part of the Bompon watershed it was categorized as an active landslide with a type of landslide namely slide. The location consists of two parts, namely the top of the hill and the middle slope with the use of mixed garden land. The recapitulation conducted shows that there are 143 trees. Calculation of the biomass analyzed at the top of the hill and the middle slope was 231.8488 kg at the top of the hill and 995.9895 kg at the middle slope.
