Abstract

The research aimed to analyze selected properties of peat degradation on different land uses and the sustainable management. The research area is located in the lowland dome peats in the catchment basin of Sibumbung River and Sibotak River in Sub District of East Pedamaran, OKI South Sumatra. The research method used an experimental design of Randomized Completely Block Design with two Blocks and five treatments (Site A: intercropping between oil palm and pineapples; Site B: oil palm plantations, Site C: peat forest; Site D: swamp bush; Site E: swamp grass). The research resulted that drainage and land uses decrease some properties of peats, namely C/N ratio, total pore space, fiber and ash content as well as organic C on cultivated peats and are significantly different at level of 5% compared with uncultivated peats. Bulk density increased due to peat compaction and groundwater table on cultivated peats, which is getting deeper, and significantly different compared with uncultivated peats. All soil series do not show any change because of drainage and different land uses. Sustainable peat management can be implemented through three approaches, namely managements of water, soil and crops.

Abstract

The research aimed to (1) describe changing biomass during the burning process, (2) characterize the nutrient loss due to biomass burning, (3) analyse the financial loss of nutrient transfer, and (4) compare farmer’s income among three land typologies. This research was conducted in tidal wetlands Talang Sepucuk, OKI District, South Sumatra with a slope of 0-3 %. Three selected land typologies (B, C and D) are located in the area adjacent to one another with distance < 1.200 m. The natural vegetation data and paddy yields was recorded by squares method, i.e. 25 x 25 m at each study site, dried and weighed and analyzed in the laboratory. The research resulted that the nutrient transfer due to biomass burning was in range of Rp 49.98-51.62 Mills/ha/year. The farmer’s income of the sonor system was very small (Rp 3.61-3.97 Mills/ha/year), it was only about 7 % of the total financial loss of nutrient transfer). The remaining value (93 %) is beyond the capacity of farmers to harvest natural resources. This value (93 %) is classified as one of the biggest negative impact of the sonor system to be paid by the all people. The government must intervene to make the public policy by giving direct subsidy to farmers NOT to burn biomass in the sonor system with compensation of at least 2 (two) times of farmer’s income from the sonor system (around Rp 7.66 Mill. Rp/ha/year). If farmers still continue to apply the sonor system by using fire, then there is very little opportunity for us to manage the nutrients loss due to biomass burning. The preventive and proactive approach is the best way how to manage the land resources.

Abstract

Banjir dan penurunan kualitas tanah merupakan dua isu yang banyak menjadi permasalahan di berbagai Kota di Indonesia. Kota Jambi merupakan salah satu wilayah dengan jumlah penduduk terpadat di Provinsi Jambi, hal ini menyebabkan peningkatan wilayah permukiman menjadi sangat pesat. Beberapa wilayah permukiman bahkan dibuat pada wilayah dengan elevasi rendah sehingga rentan terjadi bencana banjir. Salah satu upaya yang dapat digunakan untuk mengembalikan air ke bawah permukaan adalah lubang resapan biopori. Lubang resapan biopori dibuat di tiga wilayah berbeda di Perumahan Bougenville, Kota Jambi. Hasil penelitian menginformasikan bahwa pembuatan Lubang Resapan Biopori mampu meningkatkan laju infiltrasi dan kapasitas infiltrasi. Penggunaan ukuran diameter lubang resapan biopori yang berbeda yaitu 10 cm dan 20 cm tidak menunjukkan perbedaan laju infiltrasi dan kapasitas infiltrasi. Penambahan limbah organik pada lubang resapan biopori yang berbeda yakni limbah organik rumah tangga dan limbah organik alam tidak menunjukkan perbedaan laju infiltrasi dan kapasitas infiltrasi

Abstract

Watermelon is one of the horticultural commodities in the fruit group which is quite attractive to the people of Indonesia, especially people in the lowland areas. Besides that, the lowlands are known for their fertile soil characteristics so that people can easily cultivate crops. However, there are still problems faced by farmers in planting watermelons, one of which is the few varieties of watermelon plants that can meet the quality of the fruit according to market demand in certain areas. This can be done with several efforts, namely pruning the fruit and giving Plant Growth Regulator(PGR). In addition, farmers can also optimize agricultural land by planting watermelons between annual crops such as immature oil palm (TBM).This research was carried out experimentally in the form of a factorial experiment arranged in a randomized block design (RBD) consisting of 2 factors, namely the first factor with 4 gibberellin application treatments (0 ml l-1; 3 ml l-1; 5 ml l-1 and 7 ml l-1) and the second factor with 4 pruning treatments (without pruning; leaving 1 fruit/plant; leaving 2 fruits/plant and leaving 3 fruits/plant), each treatment was repeated 3 times. The results showed that giving gibberellin concentrations of 7 ml l-1 and pruning the fruit leaving 1 fruit per plant gave the highest yields for each parameter observed both in quantity and quality for growth and production of watermelon plants. Farmers can optimize oil palm land so that it helps the economy during immature oil palm plantations (TBM).

Abstract

One material that has the potential to replace cocopeat and peat for planting media is rice husk biochar because it has the ability to increase pH, has a porous structure and is rich in potassium. Currently, Acacia crassicarpa nurseries generally use polybag and polytube containers which often have negative effects on rooting and problems in the planting process in the field. The use of paper bags as an alternative to containers that have a larger volume advantage than polytubes, and can be directly planted in the field requires a more in-depth study. This study aims to examine the optimum dosage of rice husk biochar and container type for the growth of Acacia crassicarpa seedlings in nurseries. This study used a Split Plot design with a factorial pattern, each consisting of 3 main plots, namely polybag, polytube and paperbag and 4 subplots consisting of 4 doses of husk charcoal biochar, respectively 0%, 10%, 30% and 50 %. Each treatment was repeated 3 times. The variables measured were media porosity, media pH, plant height, stem diameter and seedling root volume. Data were analyzed using the ANOVA test and then tested further with the DNMRT test at α5%. Analysis using SPSS software version 2.3. The results indicated that the interaction between the type of container and the dosage of rice husk biochar only had a significant effect on the porosity variable. The type of container alone did not show a significant effect on soil pH variables, but had a significant effect on plant height, stem diameter and root volume variables. Polybags give the best results for the height and diameter of the seedlings. Polytube gave the best effect on root volume variables, paperbags showed the least circular roots. This variable was not tested but visually shows a significant difference. Treatment of single doses of biochar had a significant effect on soil pH, seedling height, seedling diameter and seedling root volume. There was a tendency to increase soil pH and root volume with increasing doses of biochar. The best seedling height and diameter variables were obtained at a dose of 10% biochar, this gives an indication that the biochar dose is optimum for seedling growth

Abstract

Tunas Makmur Farmers Group I of Ibru Village, Mestong District, Muaro Jambi Regency, Jambi Province has not yet made optimal use of a large amount of agricultural, plantation and industrial waste, due to farmers' lack of knowledge about biochar and its use to improve soil productivity. For this reason, the implementing team offers an easy, cheap and sustainable solution to manage and utilize abundant sources that can be used as a source of biochar. The objectives of implementing this community service activity can be achieved through: 1) counseling and training about the benefits of biochar to improve the physical and chemical properties of soil, 2) demonstration of making biochar from agricultural, plantation and industrial waste using drum pyrolysis, 3) assistance in calculating the dose given and application in the field through demonstrations on partner land on how to use biochars properly. Partners in this activity earn their main income from being food crop and plantation farmers. Agricultural, plantation and industrial waste is usually piled up on land and wasted because farmers do not yet have knowledge about the benefits of this waste. After conducting socialization and education through counseling and demonstrations about making biochar from agricultural and industrial waste, farmers have the motivation to use this waste as a source of soil carbon and as a soil conditioner.

Abstract

Daerah Aliran Sungai (DAS) Kenali Besar meliputi sebagian Kota Jambi dan Kabupaten Muaro Jambi, alirannya melewati Kecamatan Kenali Azam Bawa, Bagan Peet, Mayang Mangurai, Beliung, Rawasari, Kenali Besar dan Kecamatan Mestong. Sungai ini kemudian mengalir ke Danau Kenali, yang selanjutnya mengalir menuju Sungai Kenali Besar dan akhirnya ke Sungai Batangari. Salah satu karakteristik Daerah Aliran Sungai (DAS) yang dipengaruhi oleh faktor alam ialah morfometri. Morfometri ialah aspek kuantitatif bentuk lahan, termasuk kemiringan, bentuk lereng, panjang lereng, ketinggian, perbedaan ketinggian, bentuk lembah, dan pola drainase (Verstappen, 1985). Morfologi Daerah Aliran Sungai berperan penting dalam mengatur aliran air hujan dalam wilayahnya. Oleh karena itu, diperlukan suatu metode yang cepat, otomatis, dan terintegrasi untuk memperoleh parameter morfometrik DAS, salah satunya dengan menggunakan model elevasi digital (DEM) dan sistem informasi geografis (SIG).
