DAS Maluka seluas 89.506,19 Ha terdapat sub DAS Banyu Irang dan sub DAS Bati Bati serta secara administrasi tersebar di 3 kabupaten/kota yaitu Kabupaten Tanah Laut, Kabupaten Banjar dan Kota Banjarbaru Provinsi Kalimantan Selatan. DAS Maluka didominasi kekritisan lahan agak kritis 63%, kelerengan lereng didominasi tingkat kelerengan 0-8% 79,88%, tutupan lahan didominasi tutupan lahan perkebunan 17,91%, Kerusakan lingkungan di DAS Maluka telah menjadi keprihatinan banyak pihak, hal ini ditandai dengan meningkatnya bencana alam yang dirasakan, seperti bencana banjir, tanah longsor dan kekeringan yang semakin meningkat. Rendahnya kapasitas infiltrasi sebaliknya tingginya Surface run off penyebab utama terjadinya bencana alam yang terkait dengan tata air. Penelitian ini menggunakan model Horton yang bertujuan mengetahui infiltrasi terhadap berbagai kelas umur tegakan karet (Hevea brasiliensis). Metode penelitian menggunakan doubel ring infiltrometer pada kelas umur 4 tahun, 8 tahun dan 12 tahun. Hasil penelitian diperoleh bahwa:1) Kapasitas infiltrasi 96,906 mm/jam, 103,981 mm/jam dan 104,651 mm/jam; 2) volume infiltrasi sebesar 93,432 m3, 95,945 m3, 591 m3; 3) semakin tinggi kelas umur tegakan karet semakin tinggi laju, kapasitas dan volume infitrasi. Kata kunci : infiltrasi, surface run off , vegetasi tegakan karet. The Maluka watershed covers an area of 89,506.19 Ha, there are the Banyu Irang sub-watershed and the Bati Bati sub-watershed and are administratively spread across 3 regencies / cities, namely Tanah Laut Regency, Banjar Regency and Banjarbaru City South Kalimantan Province. The Maluka watershed is dominated by criticality of the rather critical land 63%, the slope is dominated by the slope level of 0-8% 79.88%, land cover is dominated by plantation land cover 17.91%, environmental damage in the Maluka watershed has become a concern of many parties, this is indicated by increasing perceived natural disasters, such as floods, landslides and increasing drought. The low infiltration capacity, on the other hand, is the high Surface run off, the main cause of natural disasters related to water management. This study uses the Horton model that aims to determine infiltration of various age groups of rubber stands (Hevea brasiliensis). The research method uses a doubel ring infiltrometer in the age class of 4 years, 8 years and 12 years. The results showed that: 1) Infiltration capacity of 96,906 mm / hour, 103,981 mm / hour and 104,651 mm/ hour; 2) infiltration volume of 93,432 m3, 95,945 m3, 591 m3; 3) the higher the age of rubber stand age, the higher the rate, capacity and volume of inflation. Keywords: infiltration, surface run off and rubber stand vegetation.

This research aims to examine the characteristics of infiltration of various age classes of rubber tree stands (Hevea brasiliensis) and physical properties of soil. This research was carried out in the Banyu Irang sub-watershed of the Maluka Banjarbaru watershed, for 2 months. Determination of the location of infiltration was done by purposive sampling by using 3 replications in the 4 year, 8 year and 12 year age classes in the rubber tree stand, so that 9 replications were obtained. Infiltration measurements using a doubel ring infiltrometer, soil samples from the study site were then tested in the laboratory to determine the physical properties of the soil, namely soil texture, bulk density and porosity. The results of soil analysis on three age classes of rubber tree stands were obtained by clay and sandy clay. Has an average bulk density value in the 4 year, 8 year, 12 year age class of 1,57 gr/cm3, 1,31 gr/cm3 and 1,15 gr/cm3 and its porosity is 33,29 gr/cm3, 38,54 gr/cm3 and 44,17 gr/cm3. The infiltration capacity of 4, 8 and 12 years old is 96,906 mm/hour, 103,981 mm/hour and 104,651 mm/hour and the infiltration volume is 93,432 m3, 95,945 m3, 591 m3.Penelitian ini bertujuan untuk mengkaji karakteristik infiltrasi terhadap berbagai kelas umur tegakan pohon karet (Hevea brasiliensis) dan sifat fisik tanah. Penelitian ini dilaksanakan di Sub DAS Banyu Irang DAS Maluka Banjarbaru, selama 2 bulan. Penentuan lokasi infiltrasi dilakukan secara purposive sampling dengan menggunakan 3 kali ulangan di kelas umur 4 tahun, 8 tahun dan 12 tahun di tegakan pohon karet, sehingga diperoleh 9 kali ulangan. Pengukuran infiltrasi menggunakan alat doubel ring infiltrometer, sampel tanah dari lokasi penelitian kemudian dilakukan uji pada laboratorium untuk mengetahui sifat fisik tanah yaitu tekstur tanah, bulk density dan porositas. Hasil analisis tanah pada tiga kelas umur tegakan pohon karet diperoleh tekstur liat dan lempung liat berpasir. Memiliki rata-rata nilai bulk density pada kelas umur 4 tahun, 8 tahun, 12 tahun adalah sebesar 1,57 gr/cm3, 1,31 gr/cm3 dan 1,15 gr/cm3 dan porositasnya sebesar 33,29 gr/cm3, 38,54 gr/cm3 dan 44,17 gr/cm3. Kapasitas infiltrasinya dari umur 4, 8 dan 12 tahun 96,906 mm/jam, 103,981 mm/jam dan 104,651 mm/jam dan volume infiltrasi sebesar 93,432 m3, 95,945 m3, 591 m3.

The purpose of this study is to analyze the characteristics, the level of criticality of the land, and determine the direction of land and forest rehabilitation (Green Revolution) based on the level of criticality of land in the Bati Bati Sub DAS, Maluka DAS, Tanah Laut Regency.The method used in this study was carried out by determining the location for data sampling using purposive sampling technique, namely the sample points were determined deliberately and data collection was carried out directly in the field in accordance with predetermined observation points through the overlay results of soil types, slope class and land cover for get primary data and secondary data. The results obtained from the analysis of the level of land criticality, namely the characteristics (productivity, slope, erosion, and management) based on the calculation of scores and weights show that the greatest value is in the 7 plantation land units of 380 (critical potential), while the smallest characteristic value is in land units. 39 and 37 alang-alang land units of 220 so that this land unit is categorized as critical. Areas with plantation land cover and shrubs have the same level of land criticality, namely critical to critical potential, while the level of land criticality in alang - alang land cover is at the level of somewhat critical to critical. Forest and Land Rehabilitation (RHL) based on the level of criticality of the land has three types of directions, where in rather critical areas need to be agroforestry and terassering, critical areas with revegetation, and very critical areas need reclamation and revegetationTujuan dari penelitian ini adalah Menganalisis karakteristik, tingkat kekritisan lahan, dan menentukan arahan rehabilitasi hutan dan lahan (Revolusi Hijau) berdasarkan tingkat kekritisan lahan di Sub DAS Bati Bati DAS Maluka Kabupaten Tanah Laut. Metode yang digunakan dalam penelitian ini dilakukan dengan menentukan tempat pengambilan sampel data menggunakan teknik purposive sampling yaitu titik sampel ditentukan secara sengaja dan pengumpulan data dilakukan secara langsung di lapangan sesuai dengan titik pengamatan yang telah ditetapkan melalui hasil overlay jenis tanah, kelas kelerengan dan tutupan lahan untuk mendapatkan data primer dan data sekunder. Hasil yang diperoleh dari analisis tingkat kekrtisan lahan yaitu karakteristik (produktivitas, lereng, erosi, dan manajemen) berdasarkan perhitungan skor dan bobot menunjukan bahwa nilai terbesar berada pada unit lahan 7 perkebunan sebesar 380 ( Potensial kritis), sedangkan nilai karakteristik terkecil berada pada unit lahan 39 dan unit lahan 37 alang-alang sebesar 220 sehingga unit lahan ini dikategorikan kritis.Kawasan dengan tutupan lahan perkebunan dan semak belukar memiliki tingkat kekritisan lahan yang sama yaitu potensial kritis sampai kritis, sedangkan tingkat kekritisan lahan pada tutupan lahan alang - alang berada pada tingkat agak kritis hingga kritis. Rehabilitasi Hutan dan Lahan (RHL) berdasarkan tingkat kekritisan lahan memiliki tiga jenis arahan, dimana pada kawasan agak kritis perlu diadakan agroforestry dan terassering, kawasan kritis dengan revegetasi, serta kawasan sangat kritis perlu dilakukan reklamasi dan revegetasi
