Abstract One of the food diversification strategies of coconut commodity is to process it into Pliek U. Pliek U is a typical food of the Province of Aceh, Indonesia, which in its processing stage requires a drying process. So far, Pliek U drying process is often conducted conventionally through direct drying (sun drying), so that Pliek U produced is susceptible to dust and other dirt contamination. This research aimed to design a Pliek U dryer using Dafa type solar energy. The Dafa type solar energy dryer used a turbine ventilator with a vertical axis wind turbine equipped with two solar collectors. This turbine had a simple shape and construction and was arranged like the letter S. While the two parts of the solar collector were used to collect energy from the sun directly. In the experiment, the blank test was carried out in the time range, namely from 10.20 am to 04.50 pm in sunny weather, with an interval of 30 minutes for each temperature data recording. The empty test results of the Dafa type solar energy dryer showed that the average shelf temperature was 44.21 °C, the collector temperature was 45.64 °C, and the ambient temperature was 31.14 °C. This initial test revealed that the performance ability of the tool was very effective in maintaining temperature during the drying process, so that further tests using materials for drying Pliek U may be carried out.
Abstract Faunus ater is a favoritemollusca that is often found on the Bale River. Local people use these snails as food for consumption along with their main food. Bale River itself is located adjacent to the cement factory, used water washing machines distributed to the river is feared to support the presence of lead (Pb) and zinc (Zn) metals in the river. This study aims to analyze the relationship of Pb and Zn content in sediments to the content of Pb and Zn in Faunus ater. Data collection was carried out in Februari until April 2018. The relationship between Pb and Zn content in sediments with Pb and Zn content in the body of Faunus ater was analyzed by correlation analysis. The results of the data analysis showed that the metal content of Pb and Zn in sediment and Faunus aterwere found to vary. The highest Pb content in sediment was found at station 2 in March, amounting to 32.87 mg / kg. while the highest Zn content was found at station 1 in March amounting to 84 mg / kg. The relationship of heavy metals Pb and Zn in sediments to the content of Pb and Zn in the body of Faunus ater showed a negative correlation. The conclusion of this study is that there is no correlation between the content of Pb and Zn heavy metals in sediments on the content of lead Pb and Zn in the body of Faunus ater at the Bale Lhoknga River in Aceh Besar District.

Abstract Applying soil ameliorants can suppress the Iron (Fe) toxicity of paddy cultivation in acid-sulfate soils. Humic materials can interact with Fe and Al metal ions to form chelates so that their solubility decreases. Silica plays a role in reducing the uptake of Fe and Al, reducing the Fe content on the surface of rice roots by increasing the oxidizing strength of rice roots. The research aim was to study the effect of ameliorant material formulation based on humate and silica on decreasing the Fe content in acid sulfate soils and increasing the growth of rice plants. The research was conducted in the Greenhouse, Swampland Agricultural Research Institute, Banjarbaru, from March to October 2022. The experimental design was randomized complete block factorial with the following treatments: Factor 1. Formula of soil ameliorant (F0 = 100% agricultural lime, F1 = 30% humate manufacturer+30% rice husk ash+40% agricultural lime, F2=30% water hyacinth humate+30% rice husk ash+40% agricultural lime, F3=30% water hyacinth humate+30% rice husk biochar + 40% agricultural lime, F4 = 30% humate manufacturer+30% rice husk biochar+40% agricultural lime), Factor 2. Dosage of soil ameliorant (D1 = 1 t/ha, D2 = 2 t/ha, D3 = 4 t/ha). Parameters observed were soil Fe content, available P and soil pH, plant height, and number of rice tillers every two weeks. The results showed that the formula F3, namely 30% water hyacinth humic acid + 30% rice husk biochar + 40% agricultural lime, was capable of decreasing soil Fe levels from 540ppm (F0) to 422 ppm and increasing soil pH from 4.23 (F0) to 4.48 and availability of P from 27 ppm (F0) to 55.20 ppm in acid sulfate soils. In addition, the formula can also increase the growth of rice plants. Improvements in soil chemical properties and plant growth are expected to increase the productivity of Inpara 8 rice plants in acid-sulfate soils.
The cause of the histological damage of Faunus ater (gastropod mollusk) gonad has been identified in the samples from two rivers, namely Bale River and Reuleng River which flow through residential, agricultural and industrial areas.The heavy metal concentration within the tissue of Faunus ater was analyzed with Atomic Absorption Spectrophotometer (Shimadzu AA 630).Meanwhile, the histological damage on gonads was observed microscopically.Afterwards, the damage levels obtained from the two respective rivers were compared and analyzed with t-test.The results confirm the histological damage that occurred in the gonads of Faunus ater collected from the two rivers.The gonadal damage of female Faunus ater from both rivers was found not to be significantly different, observed by the number of developed and damaged oocytes.It was also found that the gonads of male Faunus ater collected from Bale Riverl, have higher quantity of spermatogenic cells, in which they experience greater necrosis than the ones from Reuleng River.
BACKGROUND: Faunus ater is one of the macrozoobenthos that is often consumed by the community, especially in the Leupung and Lhoknga areas, Aceh Besar District. The presence of Pb and Zn is suspected to be able to damage the body cells of F. ater, especially the ovotestis organ. Ovotestis is an organ in mollusks in general that can produce egg cells and sperm cells simultaneously. AIM: The purpose of this study was to analyze the level of damage to the Ovotestis of F. ater based on the state of the damaged Ovotestis cells. METHODS: The method of this research method is F. ater that samples were taken from Bale and Reuleung River, each river is divided into three stations and at each station, three samples of F. ater are taken. Ovotestical histopathological analysis was carried out at the Histology Laboratory, Faculty of Veterinary Medicine, Syiah Kuala University. Preparation of ovotestis histology preparations using the paraffin method. Previously, F. ater was terminated and carcass surgery was performed. The level of damage to female gametes and male gametes was carried out descriptively by observing gonadal cells undergoing necrosis, hypertrophy, and lysis. Observation of the level of damage to the ovotestis tissue of F. ater was carried out using a cell damage scoring system, namely, the level of damage, the type of damage, and the scoring value. RESULTS: The level of tissue damage to the ovotestis organ of F. ater was at level III with a score of 6. The highest percentage of damage occurred in Krueng Bale, namely, 19.027% for male gonads and 42.687% for female gonads. While the highest percentage of damage to ovotestis organ occurred in Krueng Reuleung 15,489% for male gonads and 40,695% for female gonads. CONCLUSION: The result shows that there was damage to the gonads of F. ater in Krueng Bale and Krueng Reuleung based on the number of fully-formed oocytes/sperm, the number of incompletely formed oocytes/sperm, and the number of damaged oocytes/sperm.
Penelitian yang berjudul Potensi Limbah Air Cucian Beras sebagai Pupuk Organik Cair (POC) pada Pertumbuhan Sawi Hijau ( Brassica juncea L) dilatar belakangi oleh kebutuhan sawi di kalangan masyarakat yang terus meningkat setiap tahunnya. Tingginya kebutuhan sawi disebabkan oleh tersebar luasnya informasi tentang tingginya nilai gizi yang terkandung didalamnya.
