Abstract

Kebun Raya Sambas merupakan satu-satunya kebun raya di Kalimantan Barat yang memiliki zona atau wilayah riparian. Kemiringan lereng pada Zona Koleksi Tumbuhan Riparian Kebun Raya Sambas yang bervariasi menyebabkan kadar air tanah lapangan berubah-rubah, hal ni akan mempengaruhi pertumbuhan pada tanaman. Penelitian ini bertujuan untuk mempelajari hubungan antara kadar air tanah lapangan terhadap muka air tanah pada lahan basah atau Zona Riparian Kebun Raya Sambas. Pengangambilan sampel tanah meliputi dua jalur yaitu jalur U dan X pada zona riparian, sebanyak 6 sampel yang diambil pada setiap jalurnya dengan kedalaman 0-30 cm. Jumlah keseluruhan sampel pada zona riparian sebanyak 12 sampel tanah utuh dan terganggu. Parameter sifat fisika tanah meliputi fraksi tekstur tanah, bobot isi tanah, porositas total tanah, konduktivitas hidrolik tanah, kemantapan agregat tanah, dan kadar air tanah lapangan. Hasil penelitian menunjukkan bahwa korelasi kedalaman muka air tanah dengan sifat fisika tanah memiliki nilai sangat rendah (fraksi pasir, fraksi debu dan kemantapan agregat tanah) dan rendah (fraksi liat, bobot isi, porositas total dan konduktivitas hidrolik). Hasil analisis Kadar air kondisi lapangan (KAL) memiliki nilai regresi 0,41 (sedang) dan kekuatan pengaruh korelasi 17,11 %. Kadar air kapasitas lapangan (KAKL) memiliki nilai regresi 0,06 (sangat rendah) dan  kekuatan   pengaruh   korelasi 34 %.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan penggunaan lahan dan kedalaman tanah terhadap sifat fisika tanah. Penelitian ini dilaksanakan di Desa Semadin Lengkong, Kabupaten Melawi. Sampel tanah setiap lokasi penelitian diambil pada 6 titik pengamatan setiap lahan dengan kedalaman 0-30 cm dan 30-60 cm. Jumlah keseluruhan sampel pada tiga penggunaan lahan (kelapa sawit, karet dan padi ladang) sebanyak 36 sampel tanah utuh dan 6 sampel tanah komposit. Analisis statistik menggunakan Anova dua arah dan uji lanjut DMRT. Parameter sifat fisika tanah meliputi fraksi tekstur tanah, bobot isi, porositas total, kadar air kapasitas lapangan, laju permeabilitas, dan kemantapan agregat. Parameter sifat kimia tanah meliputi C organik, nitrogen total dan pH tanah. Hasil penelitian menunjukkan bahwa fraksi tekstur tanah pada tiga penggunaan lahan didominasi oleh kriteria lempung berdebu. Penggunaan lahan memberikan pengaruh terhadap nilai bobot isi, pada lahan karet memiliki nilai bobot isi tertinggi (1,07 g/cm3). Selanjutnya kedalaman tanah juga memberikan pengaruh terhadap sifat fisika tanah yaitu bobot isi tertinggi pada kedalaman 30-60 cm (1,08 g/cm3), porositas total tertinggi pada kedalaman 0-30 cm (64,44%), kadar air kapasitas lapangan tertinggi pada kedalaman 0-30 cm (57,73%), laju permeabilitas tertinggi pada kedalaman 0-30 cm (0,52 cm/jam), dan kemantapan agregat tertinggi pada kedalaman 30-60 cm (86,26%).

Abstract

This study aims to study the differences in the physical properties of peat soils in rubber and oil palm plantations in Rasau Jaya III Village Rasau District Kubu Raya District. The parameters of this study are, peat depth, peat maturity, measurement of ground water level depth, content weight, water content capacity field, total porosity, permeability, and some chemical properties, peat soil in people's rubber and oil palm plantations in Rasau Jaya District, Kubu Raya Regency.  Measurement of peat depth is taken up to the mineral soil boundary, has a 74 cm rubber peat depth and 66 cm oil palm. The level of maturity of both fields at the sapric level. The water resistant surface on rubber land is 70 cm and oil palm land is 58.8 cm. Average bulk density of depth 0 "“ 30 cm rubber land 0.34 g/cm3, palm 0.31 g/cm3. Depth 30-60 cm rubber 0.28 g/cm3, palm 0.38 g/cm3. Average field water capacity depth of 0-30 rubber fields 74, 63% palm 85.19%. While at a depth of 30-60 cm rubber land has 71.58% oil palm area of 84.58% vol. The average porosity of total soil depth of 0-30 cm palm oil is 86.96% higher than rubber area 82.37%. The average total porosity of soil at a depth of 30-60 cm is lower oil palm 81.82% rubber land 86.82% and both lands are classified as very porous criteria. The mean permeability values based on the t-test results were not significantly different.

Abstract

Isosceles Triangle Plants (ITP) are wave-breaking and sediment-trapping structures with a triangular shape, arranged continuously in a zigzag pattern and made of bamboo. Mangrove rehabilitation in Sengkubang Village has been carried out independently by planting Rhizophora stylosa Griff mangrove species. This study aims to examine the physicochemical properties of soil both inside and outside the ITP structures. The study results showed that redox potential varied, with both positive and negative values. Salinity ranged from 5.228 to 5.257 mmhos/cm on the outside and from 4.971 to 5.657 mmhos/cm on the inside. Total Dissolved Solids (TDS) were between 2,754 ppm and 2,971 ppm. Organic matter content ranged from 2.754% to 2.971%. Soil acidity (pH) tended to be neutral to slightly alkaline, between 7.59 and 7.91. The soil fraction composition was dominated by silt (83.42% to 93.00%), followed by clay (6.64% to 16.24%) and sand (0.32% to 0.52%). All soil structures were massive. Soil bulk density ranged from 0.54 g/cm³ to 0.58 g/cm³. Total soil porosity was high, between 75.60% and 78.39%, as was the field capacity water content (74.36% to 77.32%).

Abstract

Indonesia memiliki salah satu kawasan gambut terluas di dunia, yaitu sekitar 47% dari total gambut tropis global, sehingga menjadikan Indonesia sebagai negara dengan lahan gambut terluas di Asia Tenggara (Herman, 2016). Kelapa sawit merupakan komoditas perkebunan utama dengan nilai ekonomi yang tinggi; namun, budidayanya di lahan gambut dapat mengubah kondisi hidrologi. Sebaliknya, semak belukar merupakan vegetasi alami yang berperan dalam menjaga keseimbangan ekosistem serta dapat dijadikan acuan dalam penelitian lingkungan. Penelitian ini bertujuan untuk membandingkan kedalaman muka air tanah gambut pada berbagai jarak dari saluran drainase di lahan kelapa sawit dan semak belukar di Desa Kuala Dua, Kabupaten Kubu Raya. Hasil penelitian menunjukkan bahwa pada lahan kelapa sawit, jarak terhadap saluran drainase secara konsisten memengaruhi muka air tanah setiap minggunya. Pada lahan semak belukar, pengaruh tersebut hanya terlihat pada minggu pertama hingga ketiga, sementara pada minggu keempat hingga kedelapan tidak ditemukan pengaruh yang signifikan. Secara keseluruhan, kedalaman muka air tanah pada kedua tipe lahan tergolong sedang, sedangkan kedalaman muka air saluran drainase pada keduanya tergolong dalam.

Abstract

The peatland of the Coastal Area is wider than the Inland Area of West Kalimantan Province, where the peatland of the Coastal Area South Latitude is wider than North Latitude. This study aims to examine the characteristics of rainfall that occurs in the Coastal Area of the Regency/City of North Latitude and South Latitude of West Kalimantan Province which is the basis for planning sustainable peatland management. The research method analyzes the characteristics of rainfall at 4 climatology stations with the furthest and closest distances to the Equator in the Coastal Area of West Kalimantan North Latitude (Sambas and Mempawan) and South Latitude (Kubu Raya and Ketapang). The results of the study show that Climate Type A (Very Wet) except Ketapang has Climate Type B (Wet), a return period (Tr) of 2 years and a 50% chance is a very important design plan on rainfall and minimum monthly rainy days as a basis for planning water management for water management to anticipate drought on cultivated land and dry peat soil that does not return, on rainfall and maximum monthly rainy days as a basis for planning water management for land drainage to anticipate excess water that can disrupt the growth of cultivated plants, as well as a return period (Tr) of 20 years and a 5% chance (P) is a very recommended design plan on maximum daily rainfall as a basis for planning location-specific water channels so that the land does not experience flooding and drought for sustainable water management of cultivated peatland plants
