Abstract

ABSTRACT Cikembang Village, Kertasari District, Bandung Regency, is located in the Upper Citarum Sub-watershed. Cikembang, one of the water catchment villages, is a conservation area with eucalyptus plants. Eucalyptus plants in the category of Fast-Growing Species (FGS) can accelerate the process of succession of critical lands, restoration of peat ecosystems, are very adaptive to cultivate with agroforestry systems, support food security. However, the implementation of eucalyptus plants in Cikembang Village needs to be analyzed its impact on the conservation function and the importance of economic value-added. This study aims to form a conservation modification strategy and the importance of added value to the economy of eucalyptus cultivation by taking into account land suitability and its limiting factors. The soil fertility level approach is promising for eucalyptus growth in three land locations, namely: wet soil/Tb, slope/Tk, soil near springs/Tm, with attributes of elevation, slope, rainfall, temperature, acidity, and soil organic matter. With the storie method’s assessment, the soil is in the N1 category (currently unsuitable), and the root square is produced while the soil is in the S3 category (slightly marginal). The strategy for obtaining land use to accommodate cropping patterns for conservation and agricultural interests is by applying the silvicultural system techniques (integrating plant species, environmental modification, making terraces, setting spacing, and managing fertilization maintenance, including pest control). The study also tried to accommodate the approach to producing eucalyptus leaves as raw material for eucalyptus oil processing becomes an economic added value by refining eucalyptus oil. Keywords: eucalyptus, strategy, modification, conservation, added value   ABSTRAK Kawasan Desa Cikembang, Kecamatan Kertasari, Kabupaten Bandung, terletak di Sub DAS Citarum Hulu. Cikembang salah satu desa tangkapan air menjadi daerah konservasi dengan tanaman kayu putih. Tanaman kayu putih kategori fast growing species (FGS) dapat mempercepat proses suksesi lahan kritis, restorasi ekosistem gambut, sangat adaptif dibudidayakan dengan sistem agroforestri, mendukung ketahanan pangan. Namun demikian, implementasi tanaman kayu putih di Desa Cikembang perlu dianalisis dampaknya terhadap fungsi konservasi dan kepentingan nilai tambah ekonomi. Penelitian ini bertujuan untuk membentuk strategi modifikasi konservasi dan kepentingan nilai tambah ekonomi budidaya tanaman kayu putih dengan memperhatikan kesesuaian lahan dan faktor pembatasnya. Pendekatan tingkat kesuburan tanah cukup menjanjikan untuk pertumbuhan kayu putih di tiga lokasi lahan yaitu: tanah basah/Tb, tanah kemiringan/Tk, tanah dekat mata air/Tm, dengan atribut elevasi, lereng, curah hujan, suhu, dan keasaman serta organik tanah. Dengan menggunakan pendekatan metode storie, diketahui bahwa tanah Desa Cikembang termasuk ke dalam kategori N1 (saat ini tidak sesuai), dan dengan menggunakan metode root square, dihasilkan bahwa tanah termasuk kategori S3 (sedikit marginal). Strategi yang digunakan untuk memperoleh tata guna lahan yang mengakomodasi pola tanam untuk konservasi dan kepentingan pertanian adalah pendekatan aplikasi teknik sistem silvikultur (pemaduan elemen spesies tanaman, modifikasi lingkungan, pembuatan teras, pengaturan jarak tanam, pengaturan pemupukan, pemeliharaan, termasuk pengendalian hama) serta pendekatan produksi daun tanaman kayu putih sebagai bahan baku olahan minyak kayu putih menjadi nilai tambah ekonomi dengan penyulingan minyak kayu putih.

Abstract

ABSTRACT Leachate has complex characteristics, and it is commonly processed biologically in the Leachate Treatment Plant (IPL) in Indonesia. However, as the landfill ages, the leachate becomes less biodegradable. An appropriate technique is needed to treat leachate at IPL, and one of the promising methods is advanced oxidation with O3/H2O2. This study examined the effect of air flow rate on the concentration of residual ozone (KSO) and its efficiency to remove organic compounds using the O3/H2O2 process. Leachate samples were collected as grab samples from TPA Sarimukti Bandung. As much as 1 L of leachate samples were placed in an ozone contactor equipped with a filter disc with a pore size of 100-160 µm. The dose of H2O2 was continuously added to 1.197 g/L. Compressor was used to provide airflow with variations of 2, 3, and 4 L/min. Dissolved Oxygen (DO) was measured to determine the concentration of residual ozone (KSO) and validated by examining KSO measurements with the Indigo colorimetric method. A strong relationship between KSO and DO (R2 = 0.99) was observed at an airflow rate of 4 L/min. The highest ozone mass transfer coefficient (KLa,O3) was recorded at a 4 L/minute flow rate with 0.0022 min-1 at 27 °C.  The best removal efficiency has occurred at the fastest air flow rate (4 L/min) with COD, and UV254 removal was 88.89% and 14.87%, respectively. Keywords: DO, flow variation, KSO, leachate, O3/H2O2, organic, mass transfer   ABSTRAK Karakteristik lindi sangatlah kompleks dan di Indonesia, Instalasi Pengolahan Lindi (IPL) pada umumnya menggunakan sistem pengolahan biologis. Namun demikian, seiring dengan pertambahan umur urugan sampah, lindi semakin tidak biodegradable. Teknik pengolahan tepat diperlukan untuk mengolah lindi di IPL. Salah satu teknik yang sering digunakan adalah oksidasi lanjut dengan O3/H2O2 dengan mentransferkan gas ozon ke dalam air lindi yang diukur sebagai Konsentrasi Sisa Ozon (KSO) dan menambahkan H2O2 untuk meningkatkan pembentukan OH? di dalam air.  Penelitian ini bertujuan untuk mengetahui pengaruh laju aliran udara terhadap KSO serta pengaruhnya terhadap efisiensi penyisihan senyawa organik pada proses O3/H2O2. Sampel lindi diambil secara grab sampling dari TPA Sarimukti Bandung. Sebanyak 1 L sampel ditempatkan pada kontaktor ozon yang dilengkapi filter disc dengan pori berukuran 100-160µm. Dosis H2O2 yang diberikan tetap sebesar 1,197 g/L. Udara dialirkan dengan air compressor dengan variasi debit udara 2, 3, dan 4 L/menit. Pada penelitian ini, pengukuran Dissolved Oxygen (DO) digunakan sebagai pendekatan untuk mengukur KSO. Validasi dilakukan dengan meneliti hubungan antara KSO dan DO dan pengukuran KSO dilakukan dengan metode indigo colorimetric method.  Hasil penelitian menunjukkan KSO dan DO memiliki hubungan yang kuat (R2 = 0,99) pada variasi aliran udara 4 L/menit. Laju aliran udara tercepat terjadi ketika nilai koefisien transfer masa ozon (KLa,O3) mencapai nilai tertinggi (0,0022 menit-1) pada suhu 27 oC. Hasil penelitian membuktikan efisiensi penyisihan COD (88,89%) dan UV254 (14,87%) tertinggi terjadi pada laju aliran udara tercepat selama 180 menit.

Abstract

ABSTRACT Health risk characteristics expressed as a Risk Quotient (RQ) can be carried out through an environmental health risk analysis (ARKL) approach. This approach can estimate the public health risk caused by the concentration of risk agents of particulates consisting of PM2.5, PM10, and TSP. The research on the fluctuation of ambient air particulate pollutant and its risk to public health was conducted in each sub-district of Bogor City. Author identified a total of 360 respondents to determine the community anthropometric variable of exposures for time, frequency, and duration. There are several steps that need to be carried out to obtain the RQ value, namely identification of hazards from particulate risk agents, analysis of the dose-response in the form of Reference Concentration (RFC), analysis of the exposure obtained based on anthropometric variables, and the concentration of risk agents as well as characteristics of risk levels. The risk level characteristic shows that the RQ value of TSP is always the highest one, followed by PM10 and PM2.5. The respective RQ values of TSP for male and female residents are 1.85 and 1.53. Cumulatively, the male and female population in Tanah Sareal produced the highest RQ values. Those are 4.44 and 3.36, respectively. At the same time, the lowest cumulative RQ was obtained for male and female residents in East Bogor with RQ values of 2.96 and 2.54. The RQ value of each risk agent or the cumulative RQ that is more than 1 (RQ> 1) is stated to have or has a health risk, so it needs to be controlled, while the RQ value which is less than one (1) is displayed not to need to be controlled but needs to be maintained. Keywords: particulate, risk level, exposure assessment, anthropometric characteristic, environmental health risk assessment   ABSTRAK Karakteristik risiko kesehatan yang dinyatakan sebagai Risk Quotient (RQ) dapat dilakukan melalui pendekatan Analisis Risiko Kesehatan Lingkungan (ARKL). Pendekatan ini dapat mengestimasi risiko kesehatan masyarakat yang disebabkan oleh konsentrasi agen risiko yaitu PM2,5, PM10, dan TSP di tiap-tiap kecamatan di Kota Bogor. Penulis mengidentifikasi sebanyak 360 responden yang terdiri dari laki-laki dan perempuan untuk menentukan variabel antropometri masyarakat di Kota Bogor, waktu paparan, frekuensi paparan, serta durasi paparan. Ada beberapa tahapan yang perlu dilakukan untuk memperoleh nilai RQ, yaitu identifikasi bahaya dari agen risiko partikulat, analisis dosis-respon berupa Reference Concentration (RfC), analisis pajanan yang diperoleh berdasarkan variabel antropometri dan konsentrasi agen risiko serta karakteristik tingkat risiko. Karakteristik tingkat risiko menunjukkan nilai RQ TSP selalu paling tinggi diikuti PM10, dan terendah adalah RQ PM2,5 dengan nilai tertinggi TSP untuk penduduk laki-laki dan perempuan masing-masing sebesar 1,85 dan 1,53. Secara kumulatif, penduduk laki-laki dan perempuan di Tanah Sareal menghasilkan nilai RQ tertinggi masing-masing sebesar 4,44 dan 3,36. Sedangkan RQ kumulatif terendah diperoleh untuk penduduk laki-laki dan perempuan di Bogor Timur dengan nilai RQ 2,96 dan 2,54. Nilai RQ tiap agen risiko ataupun RQ kumulatif yang lebih dari 1 (RQ>1) dinyatakan memiliki atau terdapat risiko kesehatan sehingga perlu dikendalikan, sementara nilai RQ yang masing kurang dari satu dinyatakan tidak perlu dikendalikan tetapi perlu dipertahankan. Kata kunci: partikulat, tingkat risiko, analisis pajanan, karakteristik antropometri, analisis risiko kesehatan lingkungan
