Rawa merupakan istilah umum yang digunakan untuk semua daerah yang tergenang air baik secara musiman maupun permanen dan memiliki keragaman flora dan fauna yang khas. Rawa di Kalimantan  terdapat kurang lebih sebesar 10,56 juta ha, dan di Kalimantan Selatan terdapat kurang lebih 235,677 ha. Salah satu rawa tersebut adalah rawa tanpa pohon, yang juga terdapat di Desa Bati-Batiyang didominasi oleh rumput-rumputan dan herba aquatik lainnya.Rawa tanpa pohon salah satunya di Desa Bati-Bati Kecamatan Bati-Bati Kabupaten Tanah Laut, yang data keragaman jenis vegetasi di kawasan tersebut berpotensi digunakan sebagai sumber belajar Ekologi.Tujuan penelitian ini adalah mengetahui keragaman jenis vegetasi rawa tanpa pohon di Desa Bati-Bati Kabupaten Tanah Laut, dan membuat handout pengayaan Materi Matakuliah Ekologi Lahan Basah yang valid.Metode yang digunakan adalah metode deskriptif, berupa penelitian lapangan untuk mengetahui keragaman vegetasi rawa tanpa pohon dan penelitian pengembangan untuk membuat bahan ajar berupa handout.Hasil penelitian didapatkan 12 jenis yaitu Vetiveria zizanoides (bundung), Leersia hexandra (banta), Panicum virgatum (kumpai batu), Eleocharis palustris (purun), Eleocharis acicularis (rumput purun), Eleocharis dulcis (purun tikus), Ludwegia hyssopifolia (pipisangan), Leptochlea caerulencens (parupuk),  Nyampheae pubescens (batang tanding), Ipomea aquatic (kangkung), Cynodon dactylon (rumput jarum) dan Mikania scandens (kangkung pagar).dan Indeks Diversitas (H’) sebesar 1,5544 dikategorikan keanekaragaman sedang. Validitas bahan ajar handout tentang keanekaragaman vegetasi di kawasan rawa tanpa pohon Desa Bati-bati kabupaten Tanah Laut sebagai pengayaan materi mata kuliah Ekologi Lahan Basah adalah sangat valid.Kata Kunci: Keanekaragaman, Vegetasi, Rawa tanpa Pohon, Handout

Fifteen introduced and native warm-season perennial grasses were evaluated for yield, yield distribution, and quality in south-central Oklahoma. These grasses have production potential for forage and/or biofuel. Each was harvested one to four times per year. “Alamo” switchgrass (Panicum virgatum) had a two-year average dry matter yield of 17690 kg . Over 1/3 of this production occurred in May with a crude protein (CP) range of 97–115 g . Alamo’s high yield potential and early spring growth make it attractive for spring forage production and fall biomass production. Other grasses with two-year average dry matter yields over 11200 kg  and 1/3 of yearly production occurring early in the growing season that have potential dual purpose use include “Selection 75” kleingrass (Panicum coloratum), “Midland 99” bermudagrass (Cynodon dactylon), johnsongrass (Sorghum halepense), “Carostan” flaccidgrass (Pennisetum flaccidum), and “Ermelo” weeping lovegrass (Eragrostis curvula).

Descriptive Method

The growth of weeds in the rice fields can reduce production. Weed is a disrupting plant that grows and spreads rapidly so it becomes a nutritional competitor for cultivated plants. This study aims to identify rice weeds in the fields of Rimau District, Banyuasin, South Sumatra. The research method used was descriptive method with purposive sampling on wetland rice fields of the Ciherang variety. Sampling was carried out in a critical period (3-6 weeks after planting) in rice fields. The results of weed identification obtained 6 families consisting of 15 species, namely Ageratum conyzoides L., Crassocephalum crepidioides, Cleome rutidisprema DC., Cyperusroduntus L. Cyperus compressus, Eleocharis palustris L., Frimbristylis miliacea L. Vahl, Phylanthus naruri L., Eurphobia hirta, Cynodon dactylon (L.) Press., Digitaria ciliaris (Retz.) Koel., Echinochola colona (L.) Link., Eleusinindica (L.) Gaertn., Paspalum scrobiculatum L., Ludwigia octovalvis (Jacq.) Raven. The Poaceae family is most commonly found as a rice weed in Rimau District, South Sumatra.

The regularities of changes in the resistance of different groups of fodder plants to adverse conditions were studied. This is due to the physiological properties that allow them to overcome the harmful effects of the environment. As a result of research species - plant groups with great adaptive potential to the harsh continental semi-desert conditions were identified. Monitoring observation and experimental studies showed too thin vegetation cover as a mosaic, consisting of perennial xerophytic herbs and semishrubs, sod grasses, saltwort and wormwood, as well as ephemera and ephemeroids under the same environmental conditions, depending on various climatic and anthropogenic factors. This is due to the inability or instability of plant species to aggressive living environment. It results in horizontal heterogeneity of the grass stand, division into smaller structures, and mosaic in the vegetation cover of the Kochubey biosphere station. The relative resistance to moderate stress was identified in the following species from fodder plants Agropyron cristatum, A. desertorum, Festuca valesiaca, Cynodon dactylon, Avena fatua; as for strong increasing their abundance these are poorly eaten plant species Artemisia taurica, Atriplex tatarica, Falcaria vulgaris, Veronica arvensis, Arabidopsis thaliana and other. On the site with an increasing pressure in the herbage of phytocenoses the number of xerophytes of ruderal species increases and the spatial structure of the vegetation cover is simplified. In plant communities indigenous species are replaced by adventive plant species. The mosaic of the plant cover of phytocenoses arises due to the uneven distribution in the space of environmental formation, i.e. an edificatory: Salsola orientalis, S. dendroides, Avena fatua, Cynodon dactylon, Artemisia taurica, A. lercheanum, Xanthium spinosum, Carex pachystyli, under which the remaining components of the community adapt. Based on the phytocenotic indicators of pasture phytocenoses it can be concluded that the vegetation cover is in the stage of ecological stress and a decrease in the share of fodder crops and an increase in the number of herbs indicates this fact.
