Abstract

The river is one of the important water sources and at this time the river water quality has decreased.The type of land use around the river is thought to have a significant contribution to river water quality. This research was conducted to determine of correlation between the type of land use and water quality in Rembangan River, Jember Regency.The study was carried out at four stations that passed through secondary forests, coffee plantations, rice fields and residential housing. The data of biodiversity and density of plants and physical-chemical parameters of river water were noted, and benthic macroinvertebratessamples were collected at each station. Data of biodiversity and density plants were used to determine of environmental services index (ESI) values. Benthic macroinvertebrates samples were identifiedat the family level, and after that the tolerance score and the abundance of each family was determined. The last two data were analyzed to determine of Family Biotic Index (FBI) values.The value of ESI, physico-chemical parameters of river waterand FBI were analyzedto determine the relationship between these variables by using Pearson correlation analysis (α < 0.05).The research result revealed that the type of land use (ESI) was significantly related to the biological quality of river water (FBI) as indicated by the p value > 0.05. The correlation characteristic is negative and very strong (R = 0.886). High ESI values indicate that the diversity and carbon sequestration of plant community around the river are in good condition and vice versa. Low HBI values indicate good river water quality and vice versa. Based on this research, each land use type must provide space for the natural growth of the plant communityto maintain the quality of river water to remain good. Keywords: river, benthic macroinvertebrates, land use, water quality, ESI, HBI.

Abstract

Industri laundry merupakan industri rumah tangga yang menggunakan air dan deterjen dalam melaksanakan aktivitasnya. Deterjen mengandung surfaktan, builder, filler dan zat aditif yang menyebabkan kadar materi padat tersuspensi total (total suspended solid, TSS), kebutuhan oksigen biologi (biological oxygen demand, BOD) dan fosfat dalam air limbah laundry tinggi sehingga ketika dibuang langsung ke lingkungan dapat menimbulkan pencemaran ekosistem perairan. Tujuan penelitian ini adalah untuk menentukan efektivitas tanaman lembang (Typha angustifolia L.) di lahan basah buatan dalam penurunan kadar TSS, BOD dan fosfat air limbah industri laundry. Tanaman T. angustifolia ditanam di dalam bak reaktor bervolume 44,73 L yang dasarnya diisi pasir, kerikil dan lempung sebagai media tanam. Air limbah industri laundry dialirkan ke dalam bak reaktor melalui inlet. Proses fitoremediasi berlangsung enam hari. TSS, BOD, dan fosfat air limbah laundry sebelum dan sesudah perlakuan ditentukan kadar. Hasil penelitian menunjukkan bahwa pengolahan air limbah laundry dengan tanaman T. angustifolia dalam lahan basah buatan mampu menurunkan kadar TSS, BOD dan fosfat secara berturut-turut sebesar 50 mg/L, 485,5 mg/L dan 29,1 mg/L. Efektivitas tanaman T. angustifolia dalam lahan basah buatan dalam penurunan kadar TSS, BOD dan fosfat secara berturut-turut sebesar 54 %, 22 % dan 39 %.

Abstract

Bandealit is one of the resorts in Meru Betiri National Park (MBNP). This area has many endemic floras and faunas affected by the presence of invasive alien spesies plants. These plants tend to give negative impacts on savana ecosystem among them is, Lantana camara L. The distribution of this invasive alien spesies in the savana can be used to provide information about the characteristic of the environment. This study was conducted to investigate the patterns of spatial distribution of invasive alien L. camara population in the Pringtali Resort Bandealit savana region. The characters of plant species morphology was recorded for species name identification and validation. Percent cover of the individual L. camara species was collected within 50 plots (5x5 m2), while each of coordinate species found in the plots was recorded by using GPS (Global Positioning System). Abiotic factors such as temperature, pH, light intensity, and soil moisture were measured within the plots. The location of the data collection is 5,000 m2. The distribution pattern of invasive alien L. camara population was analyzed using ArcGIS and Dispersion Morisita’s Index (Ip). The result showed that 51.7% of L. camara population grew spasially close together (clumped) or overlapped one another based on the ArcGIS. This means that L. camara individuals distributein clumped pattern. While the other individuals (48.3%) grew apart randomly from each other. This distribution pattern showed by Ip value, 0.51 was also clumped or clustered. It can be concluded that the distribution pattern ofinvasive alien species L. camara is clumped because the reproduction of plant was by seeds dispersal or vegetative buds that lived around parental individuals.Keywords: ArcGIS, Lantana camara L., Invasive Foreign Plants, Morisita index, Distribution Pattern.

Abstract

Javan langur (Trachypithecus auratus É. Geoffroy, 1812) is categorized by IUCN as a vulnerable primate species since 2008 and protected under 2018 LHK regulation. They can be found across Java Island, also in the Watangan Puger Nature Reserve (WPNR), East Java. There is no information about the population and habitat characteristics of Javan langur in WPNR except their existence. This research study aims to estimate the population structure, population density, and habitat characteristics of the Javan Langur in the WPNR, within the area of 2.6 ha. Three concentration points for daily observations were determined for 3 days. A combination of concentration count with scan sampling observation method at intervals of 30 minutes every hour of observation was done to get the data of density, position, population structure, and plant species preferred by Javan langurs. The important value, diversity Shannon-Wiener index, and plant species preferred were also analyzed. There are 26 population composed of two groups of the Javan langur occupying an area of 1,118 ha (43%). The population size estimatation for the first group was 17 individuals with a population density of 15.17 individu/ha, while that for the second group was 9 individuals with a population density of 8.02 individu/ha. The twenty-six Javan langurs are composed of complete age structure such as adult 69%, sub-adult 15%, and infant 16%. The Javan langur population was mostly found in the vegetation structure of Syzygium jambos (jambu hutan) to Pithecellobium dulce (asam manila) (IV = 45.47 to 3.88). Total 24 tree species are found in WNPR, most of the trees are used by the Javan langur as food and cover. The tree community in WPNR has medium diversity with value of 2.28. Furthermore, the Javan langur prefer Artocarpus elasticus (bendo) and Syzygium jambos (jambu hutan) at the upper strata (> 15 meters) than other trees and strata. Most of them are actively walking or jumping (locomotion) during the activity observed at the tree community.
