Abstract

Peningkatan wisata and ekonomi masyarakat pesisir umumnya menghadirkan dampak negatif pada ekosistem bakau atau mangrove. Penelitian ini ditujukan untuk mengeksplorasi struktur pohon pada populasi mangrove di kawasan pengembangan wisata teluk Mandeh Pesisir Selatan Sumatera Barat. Data berupa diameter pohon mangrove lebih dari 5 cm diukur pada dua buah line transek dengan 10x10 m plot ditempatkan secara selang, keseluruhan plot mencakup 1600 m2 area. Kerapatan dan tutupan relatif, serta analisis sebaran basal area secara vertikal dan horizontal dilakukan dengan program R 2024. Penelitian ini hanya menemukan dua spesies pohon mangrove yaitu Rhizophora apiculata dan Lumnitzera littorea, keseluruhannya berjumlah 373 pohon pada area sample atau sama dengan 2500 pohon per hektar. R. apiculata adalah jenis yang sangat dominan dengan rata-rata basal area 37 cm2, tersebar dari zona belakang hingga depan, tetapi tutupan yang menurun seiring pertambahan jarak ke arah laut. Ekosistem mangrove pada kawasan ini masih tergolong baik karena kerapatan dan tutupannya masih di atas standar baku mutu.

ABSTRACT The mangrove forest area in Pesisir Selatan reaches ±896.73 ha. It is the third largest mangrove forest in West Sumatra which can be developed as an ecotourism area. (South Pesisir Regency Environmental Service, 2019), is the strategy of the Provincial Government and the South Pesisir Regency Government to become an educational tourism center area in the field of water conservation and cultivation of mangrove plants. The problem in this case is the very limited level of education and knowledge of the community regarding mangrove plants. Based on the results of the stigma of low learning motivation, the development of scientific literacy in mangroves in Nagari Sungai Pinang needs to be guided. The aim of this community service is to create a society that loves the environment and is aware of the importance of cultivating mangrove plants and makes mangrove ecotourism an educational tourism for tourists visiting Nagari Sungai Pinang. The method used in this service activity is to provide knowledge about coastal mangrove forest areas and the benefits and influence on the economy of coastal communities. Providing education in the form of knowledge on how to seed and plant mangrove trees in the Nagari Sungai Pinang coastal area with the community. The results of this activity are to improve community welfare by utilizing mangrove forest resources, and making a good contribution to the coastal environment. In the future, this activity will preserve the habitat of mangrove trees which can be used as marine sustainable educational ecotourism in Nagari Sungai Pinang, Pesisir Selatan Regency.

Abstract

Infrastructure is major supporting factor development a state and trees are planted throughoutthe infrastructure for the green aspect, which then promotes a conflict. Conflicts defined as tree growth atadjacent infrastructure,growth of roots causing a damages as in the main campus of State University ofPadang. This study to investigate the conflict between trees and infrastructure in the main campus of StateUniversityofPadang.Treespecies,diameter,size,canopy,distancetreetoinfrastructure,numberinfrastructureandtypeinfrastructureweresampledfrom195treesconflictandnotconflict.Alltreesbelongingto 12 species diameterfrom 26,75 cmto 114,01 cm(58,8392 cm onaverage), and canopyfrom300 m² to 825 m² (555,7692 m² on average). Trees planted to concrete by 71%, 33% conflicted, paving blockby 21%, 12% conflicted, and 8% to asphalt with 55% conflicted. Conflicted trees varied species but mostlyplanted <1 m from infrastructures, tended to larger diameter and narrow canopy cover. This study showedthere is 50% risk infrastucture damage planted close and tree species with lower potential conflict prioritizedforshade treesacrossinfrastructure.

Abstract

Tubifex sp. is a natural food that fish larvae really like because it contains nutrients that are beneficial for fish growth. Tubifex sp. Generally found in shallow waters of low-flow rivers and to protect the source of Tubifex sp. As a natural food for fish larvae, cultivation must be done by adding nutrients to their food. The aim of this research was to determine the population density of Tubifex sp. by using various types of manure with a recirculation system. This research is an experimental study using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment media used were chicken manure (P1), goat manure (P2), cow manure (P3), and chicken, goat and cow manure (P4). The calculation data was tabulated and analyzed using the SPSS program. Parametric data were analyzed using analysis of variance (ANOVA) with a confidence value of 95%. If there are differences between treatments, a BNT (Least Significant Difference) test will be carried out. Population density of Tubifex sp. for 30 days, the best was treatment P2 (77063 birds) by giving a mixture of 500 gr of goat manure with 500 grams of organic mud soil, followed by treatment P1 (19564 individuals) with a mixture of 500 grams of chicken manure and organic mud soil. 1500 gr, then followed by treatment P4 (15445 heads) with a mixture of chicken manure, goat manure, cow manure 166.6 gr 500 gr of cow and 1500 gr of organic mud.

Abstract

Ethnobotany describes the direct relationship between humans and plants in traditional use. Ethnobotany has various uses for people with plants, including food, medicine, tools, infrastructure, culture, and small and medium industries in everyday life. This study aims to examine the use of plants in the daily lives of the people of Nagari Sianok, Agam Regency, West Sumatra, through an ethnobotanical approach. The research method used is descriptive qualitative, with data collection techniques through interviews, field observations, and documentation. The results of the study showed that the people of Nagari Sianok utilize 55 plant species from 33 families for various needs, including as cooking spices, traditional medicines, building materials, tools, and customary needs and small household industries.

Abstract

Back to organic farming is necessary but applying this should begin with production of the organic products in a special place called organic center, where the all possible organic products produced from organic waste in a place. This approach has started by the Usaha Tani group last year but failed in fulfilling the goals. This program was proposed to strengthening the organic center with some simple organic projects such as liquid organic fertilizer (LOF), eco-enzyme and maggot. The activities were conducted through establishing the facilities and enhancing the skills. Three of 100 kg buckets were established and were produced about 60 liter LOF, and eco-enzyme is now producing about 1680 liter within 15 of 25 kg buckets, while 450 maggots were ready to be released for making hundred thousand eggs. The farmer group is very antusias with the process and the promissing yields, and be ready for the next steps.
