Infiltration and run-off that occur in each land use have different values. The high and low values of infiltration and run-off will determine whether land use in the watershed will produce run-off or not. Maluka Watershed is one of the watersheds in South Kalimantan which has a fast water level rise but has a small infiltration rate and low slope making it prone to flooding. The purpose of this research are: (1) to analyze the rate and volume of infiltration as well as run-off in the Maluka watershed; and (2) to examine the role of land use that affects the rate of infiltration and run-off. This research was conducted in the Maluka watershed, located in Tanah Laut District, Banjar District, and Banjarbaru City. The Infiltration test was carried out using Horton Method with three repetitions five minutes apart and more than five meters away. The rainfall-runoff test was carried out using the Rational Method. The result of this research showed that in dry land agriculture the highest infiltration is 55,96 mm/hour (medium) with an infiltration volume is 25.99 mm3, the smallest infiltration located on open land is 10.27 mm/hour (low medium) with infiltration volume is 2.85 mm3, the highest runoff in plantations is 92.36 m3/second (while research) and 419.16 m3/second (within five years) while the smallest run off located on shrubs is 4.95 m3/second (while research), and 22.47 m3/second (within five years).

Infiltrasi dan aliran permukaan yang terjadi pada setiap penggunaan lahan memiliki nilai berbeda-beda. Tinggi dan rendahnya nilai infiltrasi dan aliran permukaan akan menentukan penggunaan lahan yang ada di DAS akan menghasilkan aliran permukaan atau tidak. DAS Maluka merupakan salah satu DAS yang ada di Kalimantan Selatan yang memiliki kenaikan muka air cepat tetapi laju infiltrasinya kecil serta kelerengannya rendah sehingga rawan terjadinya banjir. Tujuan dari penelitian ini yaitu: (1) Menganalisis laju dan volume infiltrasi serta aliran permukaan di DAS Maluka; dan (2) Mengkaji peran penggunaan lahan yang mempengaruhi laju infiltrasi dan besarnya aliran permukaan. Penelitian ini dilakukan di DAS Maluka yang terletak di Kabupaten Tanah Laut, Kabupaten Banjar, dan Kota Banjarbaru.

The research method used was a factorial completely randomized design with 2 factors. The first factor consisted of five levels of immersion (control, young coconut water for 12 hours, onion solution for 6 hours, bean sprouts solution for 12 hours, and hot water 60°C for 12 hours). The second factor is the depth of planting with two levels of depth (1 cm and 2 cm). The research data were first analyzed for normality using the Kolmogorov-Smirnov test, followed by analysis of variance, Least Significance Different test, and Duncan’s multiple test. The results showed that there was a relationship between planting depth and immersion had a significant effect on the percentage of germination. Seeds planted two centimeters deep and soaked in various materials had the highest germination rates. The relationship between the immersion treatment and planting depth also had a significant effect on the growth of seedling height. The interaction of soaking treatment using bean sprouts solution for 12 hours at a depth of 2 cm resulted in the highest height growth (27.70 cm), while the treatment interaction that resulted in the lowest height growth (11.20 cm) was soaking with onion solution for 6 hours at 1 cm deep. Diameter growth is also significantly affected by this interaction. Soaking with bean sprouts solution for 12 hours at a planting depth of 2 cm resulted in the largest diameter growth (0.295 cm), while soaking with onion solution for 6 hours at a planting depth of 1 cm resulted in the smallest diameter growth (0.135 cm). The results of the study recommend that in order to obtain fast-growing seedlings, it is recommended to use bean sprouts soaking for 12 hours with a planting depth of 2 cm.Tujuan penelitian ini untuk menguji persentase hidup, pertumbuhan tinggi, serta pertumbuhan diameter dari bibit mahoni (Swietenia macrophylla).

After the KTH Batu Kura was formed and get the candlenut crusher. Candlenut shells are also used to make liquid smoke which functions as a rubber latex thickener. The purpose of this study was to analyze the candlenut management system and the contribution of candlenut to the income of the community around the Community Forest Area in Galam Village, Bajuin District, Tanah Laut Regency. The tools used in this study include writing instruments, calculators, laptops. The types and sources of data needed to analyze management and contributions include primary data obtained from the community and secondary data from government agencies. Determination of respondents using saturated sampling method or census. Saturated sampling is a sampling technique when all members of the population are used as samples. Data collection is by using several approaches including interviews, field observations, and literature studies. The candlenut management data was analyzed in a systematic way, while the candlenut contribution was analyzed mathematically using four formulas, namely the formula for costs, income, net income and contribution. The results obtained from this study are candlenut management consisting of land preparation, planting patterns, maintenance, harvesting, candlenut production processes and marketing. The contribution of candlenut plants to the income of the community members of KTH Batu Kura is 31% and the contribution of non-candlenut income is 69%.Tanaman kemiri di  Desa Galam sebelum ada HKM di manfaatkan dengan cara menjual kayu kemiri karena harga jual yang murah, sulit dipasarkan, dan pemecahan biji kemiri masih manual.
