Many studies showed  that rivers in Indonesia had been polluted. This is due to the large number of human activities, both from industrial, domestic, and agricultural waste. Kampung Sasirangan is one of the settlements located on the bank of  Martapura River. The existence of industrial activities from sasirangan waste water and the large number of people deficating and throwing the garbage in the river causes water pollution. Good perceptions and good behavior is expected to increase community participation in river conservation. The purpose of this study was to determine the perceptions and behavior of the community regarding pollution that occurs in the Martapura River and to determine alternative strategies to control water pollution of Martapura River. Data was collected by questionnaires, observation, and interviews. The sample of respondents in this study used Slovin formula, amounted  100 respondents. This research use descriptive qualitative anaylisis. The results of this study show that most respondents have a poor perception of water pollution. Therefore, a strategy is needed that can make positive perceptions so that community behavior cares about environmental sustainability, that is education, wastewater treatmant plan, legislation, monitoring, and encouragement of public figure

Three experiments were conducted to study the potential use of vetiver (Vetiveria zizanioides L.) to remediate wastewater discharged from a tapioca factory. Two experiments studied the tolerance of vetiver to grow in wastewater, and the other studied the factors influencing the effectiveness of vetiver for the remediation of the wastewater. Vetiver grew well in all wastewater preparations and was able to improve wastewater quality. However, the efficacy of remediation was a function of the remediation system used (wetland or hydroponic) and the density of the plants at the start of the remediation. Vetiver remediation was more efficient in a wetland system. To achieve the water quality standard of the East Java Province, wastewater could be remediated within 30 days using a plant density of approximately 86 g dry biomass=1256 cm 2 at the time of starting the remediation, the equivalent of 6.85 t=ha.

The Amandit sub-watersheds have experienced erosion of 15-60 tons / ha / year which includes the Loksado Sub-District which enters the upper reaches. Damaged land requires actions to improve environmental conditions, one of which is Land and Forest Rehabilitation activities. To add value to the success of rehabilitation, it is necessary to select the right tree species. This study aims to obtain information on the characteristic components of the place where Loksado Subdistrict grows and provide information on the types of trees that can be developed to be planted on damaged land in Loksado District. The study was conducted using a direct survey method in the field supported by various sources with a literature review method. The primary data used is data on tree species that grow in the study location and land cover map. Data on plant growth requirements are matched with site height, rainfall in Loksado sub-district using ArgGis 10.2 software. The results of the analysis are 17 types of plants that are recommended to be planted on rehabilitation land. The dominant types suggested are Multy Purpose Tree Species (MPTS), namely durian, jackfruit, cempedak, langsat, mango, kasturi, rambai, mangosteen, pampaken, karantung, hambawang, kuini, selat, kapul, rambutan, jengkol, palm sugar, cinnamon.Sub-Sub DAS Amandit mengalami erosi 15-60 ton/ha/tahun yang mencakup Kecamatan Loksado yang masuk ke bagian hulunya. Lahan yang telah rusak memerlukan tindakan untuk memperbaiki kondisi lingkungan, salah satunya dengan kegiatan Rehabilitasi Lahan dan Hutan. Untuk menambah nilai keberhasilan rehabilitasi diperlukan pemilihan jenis pohon yang tepat. Penelitian ini ditujukan untuk memperoleh informasi komponen karakteristik tempat tumbuh Kecamatan Loksado dan menyediakan informasi jenis-jenis pohon yang dapat dikembangkan untuk ditanamn di lahan yang rusak di Kecamatan Loksado. Penelitian dilakukan menggunakan metode survei langsung di lapangan yang didukung oleh berbagai sumber dengan metode tinjau pustaka. Data primer yang digunakan adalah data jenis pohon yang tumbuh di lokasi penelitian dan peta penutupan lahan. Data syarat tumbuh tanaman dicocokkan dengan ketinggian tempat, curah hujan kecamatan Loksado menggunakan software ArgGis 10.2. Hasil analisa ada 17 jenis tanaman yang disarankan untuk ditanam di lahan rehabilitasi. Jenis yang disarankan dominan dari jenis Multy Purpose Tree Species (MPTS), yaitu pohon durian, nangka, cempedak, langsat, mangga, kasturi, rambai, manggis, pampaken, karantungan, hambawang, kuini, selat, kapul, rambutan, jengkol, aren, kayu manis.

The purpose of writing this study is to analyze the influence of coagulants to reduce the levels of dissolved metals Iron (Fe) & Manganese (Mn) from coal mine water The place of the study is in the operational area of the PT. Adaro Indonesia in Tabalong and Balangan Regencies, the object of the study of mine water samples was taken at the Settling pond (SP) X inlet located in the Wara mine area. This research was conducted with an experimental method, namely the Jar Test test with an experimental design compiled in a Non-Factorial Group Randomized Design (RAK) consisting of 6 (six) treatments with 3 repetitions. The analysis method carried out to determine the influence of coagulants on the decrease in Fe and Mn metal levels is to use the Anova and Tukey (BNJ) analysis method. The results of this study from all the treatments that have been carried out on coagulants in the study, the coagulants that have the greatest influence in reducing Fe metal levels are the use of coagulant Y with a combination of treatments with an increase in water pH (caustic soda Y) combined with fast and slow stirring (D1) of: 0,002 mg/L, treatment with an increase in water pH (caustic soda Y) combined with rapid stirring (D2) by: The 0,002 mg/L data analysis with the anova and tukey BNJ tests differed from other treatments. The coagulant that has the greatest influence in reducing Mn metal levels is the use of coagulant Y with a combination of treatment with an increase in water pH (caustic soda Y) + auxiliary coagulant Y combined with rapid mixing (F2) of: 2,509 mg/L, treatment with an increase in water pH (caustic soda Y) + auxiliary coagulant Y combined with slow mixing (F3) of: 2,518 mg/L.

There are no data on feeding behavior in birds that focus on food types and perch height from ground level while birds eat food. The research aimed to identify the type of food and analyze the height of the perch. Through transects (footpaths, inspection roads) in cultivation crops, settlements, and galam forests in Liang Anggang Protection Forest Area - Block 1, Banjarbaru, Indonesia (KHLLA-1) at 07.00 - 11.00 and at 15.00 - 17.30 and for three replications, birds at a distance of 50 m were observed. The type of food and the height of the perch when the bird ate the food were recorded. Types of food consisted of fruits / seeds, seeds, nectar, insects, fish, and others. Perch height was K-1 for height 0 - <5 m from ground level; K-2 for 5 - <10 m; and K-3 for ≥10 m. One particular bird species that eats certain types of food at certain perch height was called an event. The event ratio was the ratio of certain food types or certain perch height to all events during three replications. Twenty species (14 families) of birds are found to eat and perch. The most dominant type of food eaten is fruit and the least is seeds. Perch height for eating food in general is 0 - <5 m. The number of events at this height is 4.3 - 7.8 times more than the number of events at the height of 5 - <10 m. There is no occurrence that birds eat food at perch height of ≥10 m.Keywords: Bird, Food, Habitat, Perch, Protected Forest
