Abstract

The study on the productivity of water lily seeds in South Kalimantan’s backswamps using Wageningen method and the interview with middle traders could give more information about water lily as food commodity. Rainfall pattern in Tabalong, Hulu Sungai Utara (HSU) and Hulu Sungai Selatan (HSS) regencies is like U letter. U type is sensitive with Monsoon. This Monsoon area is affected by easterly wind and local wind. When the sun is at the south side in October to March, the Monsoon moves from west to south east, and in the other way around in April to September, the wind moves from south east to west. In April, the height of water level in some different areas was the same. The highest water level was in Paharangan subdistrict that could reach more than 100 cm and the lowest was in Hambuku subdistrict, about 80 cm. Based on the interview with middle traders, it was found out that in Hambuku subdistrict and its surrounding area, there was about 1.0 to 1.7 t/ha of water lily seeds each period. In Ampukung, Hambuku and Paharangan subdistricts, the water lily seeds were about 1.121 t/ha, 1.057 t/ha and 0.653 t/ha, respectively. If the paddy fields in Tabalong, HSU and HST regencies are 10,683 ha, 21,2252 ha, and 18,763 ha, respectively, those areas potentially can yield about 11,976.661 t/ha, 224,456.2 t/ha and 12,254.6778 t/ha. Whereas, based on radiation (Rg), the photosynthetically active radiation on very clear days (Ac), in cal cm-2 day-1, and daily gross photosynthesis rate of crop canopies on very clear days (bc) in kg ha-1 day-1 for Pm = 20 kg CH2O ha-1 hr-1, it showed that the yield of hairy water lily seeds in Ampukung, Hambuku and Paharangan subdistricts was 1.1560 t/ha, 1.1425 t/ha and 1.1021 t/ha, respectively. Hairy water lily naturally grows with seeds in soil and water in paddy field, so it can grow, develop, and produce seeds. Therefore, agronomical technique is important for further study.Keywords: hairy water lily, Wageningen, yield potential.

Abstract

High demand for clean water in Banjarmasin requires PDAM Bandarmasih to do some developments, but its efforts are hindered by the water quality of raw water to be processed. It is therefore necessary to conduct a study on the water quality of raw water sources of PDAM Bandarmasih, especially during dry season. Water quality testing was carried out by performing direct experiments in the field and in the laboratory with 7 criteria including water temperature, electrical conductivity, total dissolved solids, pH, turbidity, salinity and dissolved oxygen that were compared with the criteria of water class B (water that can be used as the raw water for drinking water), on the basis of the Regulation of the Minister of Health of the Indonesia Republic No. 492/Menkes/PER/IV/2010. Based on the analyses of water quality in the field and in the laboratory from 4 intakes namely Sungai Tabuk, Pematang Panjang, Sungai Lulut and Sungai Bilu, and the comparison of the results with the test results of water quality of the samples from PDAM taken in dry season, indicated that the amount of salt content (salinity) in two intakes, Sungai Lulut and Sungai Bilu was so high that the production of clean water from both intakes was stopped temporarily during the dry season. The service for clean water was therefore provided only at the intakes of Sungai Tabuk and Pematang Panjang during dry season, resulting in some reduction in distribution to some areas in Banjarmasin.Keywords: quality, intake, salinity, PDAM Bandarmasih.

Abstract

Humic acid is a compound of colloidal, amorphous, and complex aromatic polymer with functional groups of -COOH (carboxyl), -OH (phenol), and C = O (carbonyl). The presence of these functional groups provides a rationale for assuming that humic acids have a potential to produce phenolic, carboxylic and carbonylic compounds through cracking process. In this study the cracking was done by isolating humic acids from peat soil, and facilitated by a clay catalyst which had been activated. Humic acids were isolated by extracting the acids from the peat with NaOH and HCl. The characterization of humic acids included the determination of the ash content by gravimetric method and the analysis of the functional groups of humic acids by Infrared spectrometer (FTIR). The clay to be activated was shaped into two forms, pellets and 20-40 mesh granules. The clay was activated by immersing it in HCl and NH4NO3, and then calcined. The characterization of catalysts included the determination of acidity and the Si/Al ratio gravimetrically, as well as the analysis of the pore volume, maximum pore radius, surface area and average pore radius by Surface Area Analyzer NOVA-1000. Humic acid cracking was performed by a fixed-bed reactor system at a temperature of 400°C. The Liquid smoke, the product of cracking, was analyzed by GC and GC-MS to determine the number of compounds and major compounds contained in the liquid smoke. The results show that the isolated humic acid had ash content of 9.10%. Activated clay had acidity and Si/Al ratio higher than the clay before actifated.  Based on the analyses of GC and GC-MS it can be found out that the major compounds contained in liquid smoke, the product of humic acid cracking with 20-40 mesh catalyst at a temperature of 400°C were phenolic compounds (74.56%), and no carboxylic and carbonylic compounds as the major compounds. The activated clay can be used as the catalyst for humic acid cracking.Keywords: humic acid, catalyst, clay, cracking.

Abstract

Many species of waterbirds depend on wetland sites and related with variated habitats based on the maturity of ecosystems. The objective of this study was to determine the attendance and biodiversity of waterbirds in Rhizophora sp. mangrove stands of varying planting ages in Subang, West Java. Comparisons were made among five stands of different ages in 4 years, 12 years, 21 years, 29 years, and 38 years. Parameters compared were mangrove structure and waterbirds biodiversity. Structure of mangrove was observed in three plots measuring 10 m x 10 m, while waterbirds abundance was doing by bird watching in the three times of test. Results show that mangrove structure differed among stand ages, except in plant cover physiognomy. Average tree height at the youngest stand (4 years) was 1.56±0.33 meters, DBH 2.92±0.23 cm,, and biomass 1.45 kg m-2 ; whereas at the oldest stand (38 years), average height 8.13±5.65 meters, DBH 16.29±7.23 cm, and biomass 108.62 kg m-2. Sixteen species waterbirdss were recorded found in Rhizophora sp. mangrove stands. Six recorded species are listed as endangered in the IUCN Red List. Occurence of waterbirds shows a variety ranged from eight to thirteen species, with the lowest occurrence at the 4 years stand (9.5%) and highest at 29 years (46.2%). The general conclusion is that age (time) affected certain parameters of mangrove structure, but have no effect to waterbirds attendance. Presence of waterbirds also did not show a clear trend or pattern among stands.Keywords: biodiversity, mangrove, Rhizophora, waterbirds.

Abstract

Fly-ash (FA) is largely alkaline in nature and contains many essential elements for plant growth along with toxic metals.  Therefore, fly-ash is potential to be applied as soil ameliorate that may improve soil properties and plant growth.  In this experiment we studied the changes in chemical properties and rice production  of acid sulphate soils amended with fly ash.  Six different amounts of FA, viz. 0 (100% soil), 5, 10, 20, 40 and 75 tones FA ha-1 were added homogenously to 6 kg of soils in pots of PVC and then chemical properties of acid sulphate soils were observed after a 3-week of incubation. Subsequent of  the observation of soil properties, rice was planted onto the pots.  Results of study showed that fly-ash application improved soil pH and exchangeable Ca.  However, the availability of nitrogen of acid sulphate soils decreased significantly with fly-ash application.  The experiment also showed that fly-ash application to soils improved rice growth (height plant, number of tillers, dried-weight root and dried-weight shoot) and rice production. Application 20 tones FA ha-1 resulted in higher rice production than the application 0, 5 and 10 tones FA ha-1, and increasing subsequent the amount of FA application did not significantly increase the rice production. Results of this study demonstrate that low-level fly-ash application resulted in the improvements of soil chemical properties and rice production.Key words: fly-ash application; soil ameliorant; heavy metals; sub-optimal low land.

Abstract

This study was carried out in a monotonous swamp in Hulu Sungai Utara Regency, South Kalimantan Province. The purpose was to find out the plankton fertility in supporting fish productivity in the monotonous swamp to build a dynamic waterbody with all of its supporting aspects. The analyses were performed on plankton diversity, water quality parameters and fish production levels from 2009 to 2013. The results of Shannon-Wiener diversity index analysis for plankton in the swamp approximately exceeded the value (>2), indicating that the water condition was still good and fertile. The water quality parameters in the swamp were specific; blackish brown in color, acid, and having low level of oxygen with high ammonia concentration. The decreasing trends of fish productivity in the swamp were resulted from unselective fish catching, environmental pollutions and land-use changes converting the swamp areas into plantations and housing. Therefore, it is necessary to develop conservation areas to keep the primary productivity of the waterbody in high level, which would affect the increase in the productivity of swamp fish.Keywords: plankton, water quality, fish productivity.

Abstract

Hydro-physics of peat soils varied with their peat decomposition degree. One of the important hydro-physics is ability of the peat soil to release water as decreasing water table. Potential of water availabilty to crop growth is evidently related to this behaviour. The present study was conducted to understand modes of moisture release of peat soils as decreasing water table. Water tables were simulated using a hanging column method.  The water table was arranged at levels of 0, 10, 20, 30, 50, and 100 cm below peat column surfaces. Potential of moisture release or in oppositely potential of moisture retention could be modelled with the 3 parameter equation.  Highly decomposed peat characterized by higher bulk density and lower total porosity stored less water but retained more water.Key words: available water, bulk density, peat soil, porosity.
