Analisis data menggunakan uji Anova dan Uji BNT dengan penggunaan jenis tanaman sebagai perlakuan biofilter, yaitu Canna Indica, Echinodorus palaefolius plant, Iris pseudoacorus, penggabungan ketiga tanaman, dan tidak ada tanaman sebagai kontrol. Waktu detensi 3, 6, dan 9 hari sebagai perlakuan hari dengan tiga kali ulangan. Parameter utama adalah Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), dan amoniak. Parameter pendukung warna, bau, suhu, dan pH. Lahan basah buatan terbukti efektif dalam pengolahan limbah cair rumah sakit X dan ada perlakuan yang memberikan pengaruh beda nyata terhadap perubahan kualitas air limbah. Hasil penelitian menunjukkan efisiensi penurunan BOD dan COD terjadi pada waktu detensi 6 hari. Variasi waktu berpengaruh terhadap penurunan konsentrasi BOD dan COD. Penggabungan ketiga tanaman (C. Indica, E. palaefolius dan I. pseudoacorus) terbukti efektif sebagai biofilter dalam penurunan parameter pH (11,2%) dan warna (27,4%), serta tanaman Echinodorus palaefolius terbukti efektif sebagai biofilter dalam penurunan parameter amoniak (34%), namun pengggunaan tanaman (biofilter) dalam lahan basah buatan tidak terbukti efektif pada penurunan BOD, COD, dan suhu. Hasil penelitian ini telah memenuhi persyaratan yang ditetapkan oleh Permen KLHK No: P. 68/Menlhk/Setjen/Kum.1/8/2016 tentang Baku mutu air Limbah domestik.AbstractAn artificial wetland is a system which involves plants, soil, and microbes in the wastewater treatment. This research aims to examine the effectiveness of artificial wetland to be used for the hospital’s wastewater treatment. It also reviews the role of Canna Indica, Echinodorus palaefolius, and Iris pseudoacorus to serve as biofilters of the hospital’s wastewater. The artificial wetland is made of sand, active carbon, and gravels in lab-scale amount. The data was analysed by using Anova test and BNT test. The analysis involved several types of plants serving as a biofilter treatment, namely Canna Indica, Echinodurus palaefolius, Iris pseudoacorus, and the combination of these three plants. None served as a control plant. The detention times were 3, 6, and 9 days compounded with three-time repetitions. The main parameters were Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and amoniak. Supporing parameters included colour, odor, temperature, and pH. The artificial wetland was considered effective in the hospital’s wastewater treatment. The results also documented that some treatments had a significantly different effect towards the change of wastewater quality. The research indicated that the efficiency of BOD’s and COD’s decline occured at 6 days of detention. The variety of time affected the concetration decline of BOD and COD. The combination of three plants (E. palaefolius, I. pseudoacorus, and C. Indica) was proven effective as a biofilter which reduces pH parameter (11,2%) and colour parameter (27,4%). In addition, The Echinodorus palaefolius plant was reported effective to reduce amoniak parameter (34%). However, the use of plants (biofilter) in the artificial wetland was not effective towards the decline of BOD, COD, and temperature. The results of this research therefore have met the requirement stipulated by the Goverment regulation of KLHK (Ministry of Environment and Forestry) No : P.68/Menlhk/Setjen/Kum.1/8/2016 on the quality standards of the domestic wastewater.

This study aims to examine the composition and structure of the vegetation in the protected forest area of PT Finnantara Intiga's Sintang block and determine the pattern of forest restoration and the types of vegetation that will be used for restoration of degraded forests. This research was conducted at PT Finnantara Intiga Sintang Block which is located in five land cover areas, of which three are reference secondary swamp forest (KPPN, KPSL and river border) and two areas are degraded forest (shrub and open land). This study uses a survey method with a line plot system. The sample was determined by means of purposive sampling. Based on the results of research data analysis, the number of species found at all levels at the KPSL location was nine species, at the KPPN location there were eleven species, at the River Border location there were eight species, at the Semak Belukar location there were seven species and at the Open Land location there were four species. In general, the horizontal structure of forest stands in damaged forest ecosystems is below the horizontal structure of natural forest stands as a reference. This shows that the level of vegetation density at the location of shrubs and open land has decreased so that forest restoration measures are needed to increase the density closer to natural forest ecosystems that have not been damaged. The pattern of forest restoration for scrub areas and open land referring to the Guidelines for Restoration in Conservation Areas (JICA, 2014) is natural succession. The pattern of forest restoration that will be implemented must take into account the physical conditions of the field and local socio-cultural considerations based on stakeholder considerations. The type of vegetation for enrichment and planting activities at the shrub location refers to the KPSL location as a reference because it tends to have similarities with the community similarity index of 52.03%. The type of vegetation for enrichment and planting activities on open land locations refers to the KPPN location as a reference because it tends to have similarities with the community similarity index of 52.17%. Keywords: Composition, forest degradation, restoration, structureAbstrakPenelitian ini bertujuan untuk mengkaji komposisi dan struktur vegetasi di kawasan hutan perlindungan blok Sintang PT Finnantara Intiga serta menentukan pola pemulihan hutan dan jenis vegetasi yang akan digunakan untuk restorasi hutan terdegradasi. Penelitian ini dilaksanakan di PT Finnantara Intiga Blok Sintang yang terletak di lima areal tutupan lahan, dimana tiga areal sebagai hutan rawa sekunder referensi (KPPN, KPSL dan sempadan sungai) dan dua areal di hutan yang terdegradasi (semak belukar dan lahan terbuka). Penelitian ini menggunakan metode survey dengan cara jalur berpetak. Sampel ditentukan dengan cara Purposive Sampling. Berdasarkan hasil analisis data penelitian, Jumlah jenis yang ditemui di semua tingkatan di lokasi KPSL ada sembilan jenis, dilokasi KPPN ada sebelas jenis, di lokasi Sempadan Sungai ada delapan jenis, di lokasi Semak Belukar ada tujuh jenis dan di lokasi Lahan Terbuka ada empat jenis. Secara umum bentuk grafik struktur horizontal tegakan hutan pada ekosistem hutan yang mengalami kerusakan berada di bawah grafik struktur horizontal tegakan hutan alam yang menjadi referensi. Hal ini menunjukkan bahwa tingkat kerapatan vegetasi pada lokasi semak belukar dan lahan terbuka mengalami penurunan sehingga diperlukan tindakan pemulihan hutan untuk meningkatkan kerapatan mendekati ekosistem hutan alam yang belum mengalami kerusakan. Pola pemulihan hutan untuk areal semak belukar dan lahan terbuka merujuk pada Pedoman Tata Cara Restorasi di Kawasan Konservasi (JICA, 2014) adalah suksesi alami. Pola pemulihan hutan yang akan dilaksanakan harus mempertimbangkan kondisi fisik lapangan dan sosial budaya setempat berdasarkan pertimbangan stakeholder. Jenis vegetasi untuk kegiatan pengkayaan dan penanaman pada lokasi semak belukar mengacu pada lokasi KPSL sebagai referensi karena kecenderungan memiliki kemiripan dengan dengan indeks kesamaan komunitas sebesar 52,03%. Jenis vegetasi untuk kegiatan pengkayaan dan penanaman pada lokasi lahan terbuka mengacu pada lokasi KPPN sebagai referensi karena kecenderungan memiliki kemiripan dengan dengan indeks kesamaan komunitas sebesar 52,17%.Kata kunci: Degradasi hutan, komposisi, restorasi, struktur
