Abstract

Many forest areas in Indonesia are converted to other uses. This will impact on the hydrological conditions and the economic value of the water yield. This research applied unit analysis of Sub watersheds, with and without forest cover, Sub DAS Banjaran (forested) and Sub CAS Cangkok (not forested). Desk analysis was conducted to know land use, collecting rainfall data, instantaneous debit measurement to know the discharge of both rivers during the dry season, survey of 15 farmers using irrigation water from Sub watershed of Banjaran and 15 peasants who use irrigation water from Cangkok Sub watershed. Farmers were interviewed about the factors of production and production of rice crops to determine the economic value of water from the two sub watersheds. The results of the study show that: 1). rainfall in Baturraden is quite high (4,302 mm) but for May, July, August and September deficits for rice crops, 2). The forested sub-watershed in Baturraden is better able to regulate the water system than the non-forested sub-watershed, either quality, quantity or continuity, 3). The economic value of water for irrigation from the forested sub-watershed is Rp. 1,270,-/m3 whereas from non-forested sub-watersheds Rp. 373.5,-/m3, and 4). The economic value of water from a forested sub-watershed is Rp. 7,792,720,-/ha/year while those from non-forested sub-watersheds Rp. 2,291,796,-/ha/year. The existence of Baturraden forest is very important to the watershed ecosystem. Forested watershed was a higher economic value of water than non-forested ones so it must be conserved by involving the water user communities.

Abstract

ABSTRAK Analisis terhadap strukturisasi sistem pengelolaan lingkungan berkelanjutan di kawasan Gua Maria Kerep Ambarawa (GMKA) mengacu pada prinsip-prinsip pembangunan berkelanjutan COMHAR, yang dilakukan dengan menggunakan sistem Interpretive Structural Modelling (ISM), melalui pendekatan terhadap 6 elemen pengelolaan sebagai variabel penelitian, yaitu (1) kebutuhan yang diperlukan untuk menjalankan pengelolaan lingkungan, (2) kendala utama, (3) perubahan yang dimungkinkan, (4) tujuan dilaksanakannya pengelolaan lingkungan, (5) tolok ukur untuk menilai setiap tujuan, dan (6) aktivitas yang dibutuhkan dalam pelaksanaan pengelolaan lingkungan. Penelitian ini bertujuan untuk menemukan model struktur sistem pengelolaan lingkungan yang berkelanjutan di kawasan GMKA, melalui analisis daya penggerak (driver power) tingkat ketergantungan (dependence) serta hirarki peubah-peubahnya. Hasil penelitian terhadap driver power-dependence menunjukkan bahwa 26 peubah membentuk hubungan yang tidak stabil dengan peubah lain dan umpan balik pengaruhnya dapat memperbesar dampak. Peubah-peubah yang mendominasi umumnya berkaitan dengan kepentingan stakeholder di kawasan GMKA (pengelola, peziarah/pengunjung dan pelaku usaha/masyarakat sekitar), disusul oleh peubah yang berhubungan dengan dana, sarana serta manajemen pengelolaan dan peubah yang berhubungan dengan kondisi lingkungan kawasan. Analisis terhadap hirarki peubah-peubah, menunjukkan bahwa hubungan masing-masing peubah lebih banyak merupakan hubungan timbal balik yang saling mempengaruhi dan bukan sekedar hubungan atas dasar posisi levelnya. Kata Kunci : Lingkungan berkelanjutan, GMKA, Interpretive Structural Modelling, COMHAR. ABSTRACT Analysis on structuring of sustainable environmental management system in Gua Maria Kerep Ambarawa (GMKA) refers to the COMHAR’s principles of sustainable development, which is done by using Interpretive Structural Modeling (ISM) system, with 6 elements approach as research variables, namely (1) requirements needed to run the management of the environment, (2) the main constraint, (3) possible changes, (4) implementation of environmental management objectives, (5) benchmarks for assessing each objective, and (6) activities required in the implementation of management environment. This study aims to find a model structure of sustainable environmental management system in the GMKA region, through the analysis of driver power-dependence and hierarchy of sub-elements. The study of the relationship of the driver power- dependence showed that 26 variables forming stable relationships with other variables and feedback effects can magnify the impact. Variables that dominate commonly associated with stakeholder interests in the GMKA region (manager, pilgrims / visitors and community), followed by the variables associated with the funds, facilities, and management, and finally the variables related to the environmental conditions. Analysis of the hierarchy of the variables indicating that the association of each variable is a more reciprocal relationship of mutual influence and not just a relationship based on level position.

Abstract

Limbah cair rumah sakit merupakan salah satu sumber pencemar bagi lingkungan yang dapat memberi dampak negatif berupa gangguan terhadap kesehatan, kehidupan biotik serta gangguan terhadap keindahan sehingga harus diolah terlebih dahulu sebelum dibuang ke lingkungan. Rumah sakit RK Charitas mempunyai Instalasi Pengolahan Air limbah (IPAL) namun selama ini belum pernah dievaluasi. Baku Mutu Lingkungan (BML) Limbah Cair Rumah Sakit antara lain berupa BOD, COD, TSS, amoniak bebas, fosfat, dan total coli. Dari hasil analisis keluaran limbah cair RS RK Charitas Palembang tenyata limbah cair ini masih memiliki kadar amoniak (NH3) dan fosfat (PO4) yang masih tinggi yang tidak memenuhi baku mutu lingkungan (BML) dan syarat BML yang lain berada pada ambang batas.  Kadar PO4 sebesar 2,134-2,213 mg/l yang melebihi BML sebesar 2 mg/l dan kadar NH3 sebesar 0,174-0,186 yang melebihi BML sebesar 0,1 mg/l. Pada penelitian ini dilakukan evalusi instalasi IPAL Rumah sakit RK Charitas Palembang dari alur proses, waktu proses pengolahan, bahan pengolah air limbah, dan biaya pengolahan limbah cair dan memberikan solusi penyelesaian berupa redesain IPAL dan membuat miniatur IPAL usulan yang akan disimulasikan. Diharapkan usulan redesain Instalasi Pengolahan Air Limbah (IPAL) di Rumah Sakit RK Charitas akan menghasilkan kualitas limbah cair yang memenuhi syarat baku mutu lingkungan rumah sakit.Hospital wastewater is one of the pollution sources to the environment that can cause negative impact on human health and disruption into biotic life. Hospital wastewater must be treated before it discharged into the environment. RK Charitas Hospital Wastewater Treatment Plant (WWTP) has not been evaluated. Environmental Quality Standards (EQS) of wastewater hospital consists of BOD, COD, TSS, ammonia, phosphate, and total coliform.  The analysis results of RK Charitas Hospital Palembang’s wastewater showed that the wastewater still have high level of ammonia (NH3) and phosphate (PO4) that do not sufficient to the environmental quality standards and other terms are at the threshold. Phosphate (PO4) level is 2.134 to 2.213 mg/l  which exceeded the environmental quality standards is 2 mg/l and ammonia (NH3) level is 0.174 to 0.186 that exceeded the environmental quality standards is 0.1 mg/l. This research was conducted to evaluate the process, processing time, material, and costs of WWTP at RK Charitas Hospital Palembang and provide a solution for redesign a miniature WWTP that will be simulated. It is expected that the proposed redesign Wastewater Treatment Plant (WWTP) in RK Charitas Hospital will produce eligible effluent of hospital waste water towards environment quality standards.

Abstract

ABSTRACTChromium is hazardous pollutant for ecosystem caused chromium especially inhexavalent form is very toxic, has high solubility and mobility, teratogenicity, mutagenicity andcarcinogenicity to living system related with its oxiding power. Remediation of soilcontaminated of heavy metals was important caused soil as medium for food producing.Conventional methods for heavy metals remediation consist of physical and chemical processbut these applications were costly and less effective. One of the remediation technologies is theusing living organisms such as microorganisms, because they have ability to reduce Cr(VI) intonon toxic form, Cr(III). The aims of this research were to evaluate the reduction activity ofrhizobacterial isolate and to identify the isolate which take a role in reducing chromiumabsorption by plant. The results showed that Isolate 39 was able to grow on LB mediumcontaining 200 ppm Cr(VI). Isolate 39 reduced Cr(VI) up to 15 ppm concentration level inminimal medium. Isolate 39 has ability to reduce Cr(VI) both at growing cells and resting cellsconditions up to 100% and 51% within 18 hours, respectively. Isolate 39 increased thephytostabilization ability of chromium by Zea mays at 30 days after seeding 3.8 timescompared than control. Based on physiological characteristics and partial sequencing of 16SrRNA gene, Isolate 39 was identified as Agrobacterium sp.Key words : Agrobacterium sp, hexavalent chromium, reduction, Zea mays

Abstract

Water balance is an estimate of the availability and needs of water in a watershed area. The water balance is very important considering the human need for water resources is a major requirement. The purpose of this study includes; (1) Analyzing the distribution of the influence of rainfall observation stations in each of the Ciliman sub-watersheds, (2) Analyzing the mainstay discharge in each Ciliman sub-watershed, and (3) Analyzing the potential availability of raw water in the Ciliman watershed. The types of data used in this study are secondary data including: (1) monthly rainfall data from 4 rainfall observation stations included in the Ciliman watershed, (2) climatological data from BMKG Taktakan Serang Station in 1998-2015, (3) Map of Watershed Ciliman and (4) Population data. Data analysis methods used include; regional rainfall analysis, analysis of water availability (evapotranspiration analysis, Mock model analysis), and analysis of water requirements. The results of the analysis showed that the highest rainfall occurred in January, and the lowest rainfall occurred in August. Overall, the water available in the Ciliman watershed is sufficient with the peak occurring at the beginning and end of the year. Water availability is estimated based on surface water discharge, where peak discharge occurs in January and minimum discharge occurs in August. The water balance in general in the Ciliman watershed is quite high with the highest water debit of 61.75 m3/s occurring in March and the lowest (minimum) discharge around 5.26 m3/s in August. The total water requirement for the Ciliman watershed area is 38.86 m3/s, consisti of; Water demand for irrigation is the highest water requirement reaching 37.96 m3 s with a total irrigated area reaching 5,423 hectares. Domestic water needs are 0.48 m3/s with a total population of 314,524 people served. Water requirements for industry are 0.000040 m3/s or relatively relatively small. While the water demand for the Tanjung Lesung Special Economic Zone is 0.42442 m3/s.

Abstract

ABSTRAK Hutan Tesso Nilo merupakan kawasan dengan tingkat keanekaragaman tanaman berpembuluh dan merupakan habitat bagi satwa terancam punah yaitu harimau sumatera (Panthera tigris sumatrae) dan gajah sumatera (Elephas maximus sumatranus). Kawasan ini tidak luput dari kegiatan perambahan dan di konversi menjadi perkebunan dan permukiman. Pembukaan lahan hutan akan mengakibatkan rusaknya fungsi hutan dan mengakibatkan musnahnya berbagai jenis flora dan fauna. Tujuan penelitian ini adalah untuk mengetahui akibat yang ditimbulkan oleh perambahan hutan terhadap strukur vegetasi kawasan hutan. Metode yang digunakan adalah survei dengan menggunakan sampling vegetasi petak dalam jalur dilokasi hutan alam dan hutan terdegradasi akibat perambahan. Hasil dianalisis untuk mengetahui kelimpahan vegetasi, indeks nilai penting dan indeks keanekaragaman (Shannon-Wiener). Hasil penelitian menunjukkan bahwa perambahan hutan mengakibatkan terjadinya perubahan pada struktur vegetasi. Perambahan mengakibatkan penurunan jumlah kelimpahan vegetasi, nilai keanekaragaman, dan dominansi jenis (indeks nilai penting) baik pada tingkat semai, pancang, tiang dan pohon. Kata kunci: Taman Nasional Tesso Nilo, struktur vegetasi, perambahan ABSTRACT Tesso Nilo forest is an area with a greater diversity of vascular plants and habitat for an endangered species, namely the Sumatran tiger (Panthera tigris sumatrae) and the Sumatran elephant (Elephas maximus sumatranus). This area was not spared from encroachment and conversion to plantations and settlements. Forest clearing will cause damage to forest functions and lead to the extinction of various species of flora and fauna. The purpose of this study was to determine the consequences caused by the encroachment of the structure of forest vegetation. The method used was a survey by sampling vegetation plots in the path of the location of natural forests and forests degraded due to encroachment. The results were analyzed to determine the abundance of vegetation, an index of the importance and diversity index (Shannon-Wiener). The results showed that deforestation resulted in a change in the structure of vegetation. Encroachment degrades an abundance of vegetation, the value of diversity, and dominance type (Importance Value Index) is good for seedlings, saplings, poles and trees.
