Abstract

Many areas in Central Kalimantan have a lot of small-scale gold mining activities (illegal mining), involved thousands of gold miners. These gold mining activities had caused extensive damage to the landscape, both on land and in waters. This activities carried out aim to; (1) Developing an integrated form of business incubation in agriculture and animal husbandry for gold mining communities in 3 villages in Central Kalimantan; (2) Conduct socialization, training, and assistance to the gold mining community in cultivating chickens intensively, diversifying livestock production, and carrying out integrated agriculture in a sustainable manner; (3) Fostering productive business units from upstream to downstream in integrated agriculture, through the support of infrastructure, purchase of tools and materials, to find prospective market networks through the implementation of post-harvest processing and appropriate marketing strategies. These activities were carried out in 3 (three) villages, namely, Tuwung Village, Sigi Village, and Marang Sub-District, from September to December 2022. The results of the activity showed an increase in the participants' knowledge regarding the dangers of mercury pollution and alternative types of businesses that were more productive and environmentally friendly. The skills of the miners have also increased, in terms of chicken cultivation, maggot cultivation, and post-harvest processing and also marketing. This activity is also able to support the economy of gold miners, which is obtained from the sale of 4 main products, namely chicken products, magot products, agricultural commodities, and livestock manure compost. On average, 60% of miners stated that they were willing to shift their jobs from gold miners to workers in integrated agriculture and animal husbandry.

Abstract

Gold mining uses mercury for the gold extraction process, where the mercury content in the Kahayan watershed reaches 2.996 - 4.687 µg/l and this value exceeds the standard limit for mercury content in water. Bioremediation is one solution to reduce mercury waste pollution. Mercury bioremediation using microorganisms and adsorbents requires appropriate process steps to be effective in eliminating mercury. This study aims to determine the effect of bioremediation stages on the effectiveness of mercury (Hg) elimination in liquid media and to determine the most effective bioremediation steps for mercury (Hg) elimination in liquid media. This study used an experimental method with a nonfactorial completely randomized design consisting of treatments namely control (K), treatment 1 (T1), treatment 2 (T2), treatment 3 (T3), treatment 4 (T4), with 5 (five) times repetition. Analysis of the results of the bioremediation stages using AAS (Atomic Absorption Spectrophotometry). Data were analyzed using the One-way Anova test, LSD test and effectiveness test. The results showed that the bioremediation stage had a significant effect on the effectiveness of mercury (Hg) elimination in liquid media. The most effective bioremediation stage for mercury (Hg) elimination in liquid media is the T3 stage which starts from Mercury Waste→Microalgae→Bacteria→Red Clay→Activated Charcoal, with an effectiveness value of 89.4% in reducing mercury.

Abstract

The Black Soldier Fly (BSF) larvae, commonly known as maggot, have gained attention as an alternative source of protein for animal feed. Nutrition is a crucial factor in the growth of BSF larvae, and different organic materials have varying nutritional contents. This study aims to investigate the effect of different types and combinations of organic materials on the growth of BSF maggot and to determine the optimal type and combination for their growth. The results of the study indicate that a combination of rice bran and fruit/vegetable waste (50:50) provides the best growth for BSF maggot with an average weight of 454 g. A combination of rice bran and tofu dregs (50:50) yields a growth rate of 447 g, and chicken manure (100%) yields a growth rate of 435 g. These findings can serve as a reference for the development of alternative maggot-based feed in the livestock industry.

Abstract

Hornstedtia conica Ridl., Microsorum pustulatum Copel and Rourea fulgens Planch were medicinal plant used by  people of Dayak Tribes in Central Kalimantan for anti-tumor medicines. Although these plants has been widely used in traditional medicine, however, research and scientific evidence about their potential as anti-tumor are still very limited.  The research aims were to determine the qualitative content of phytochemical compounds and to study anti-tumor potential of these medicinal plants. This study used female Swiss Webster albino as a test animal.  Induction of tumor cell in mice used 7,12-Dimethylbenz [a] anthracene (DMBA), was done 10 times for 5 weeks.  Experiments were carried out used hexane extract from medicinal plants, every day for 7 weeks. The data obtained were analyzed descriptively. The results as follows: extracts of Hornstedtia conica Ridl., and Microsorum pustulatum Copel. contained alkaloids, while extract of Rourea fulgens Planch. contained flavonoids and saponins. All of these plant extracts were able to reduce the size and number of mice tumors. Hexane extract of H. conica was able to reduce the tumor size faster than another plants extracts. Mortality rate of mice in hexane extracts of H. conica and R. fulgens were zero- and in hexane extract of M. pustulatum it was 30%, meanwhile almost all mice in control group were died in days 15 of treatment. Based on this study, it can be concluded that hexane extract of H. conica and R. fulgens are potential as anti-tumor medicinal plants. These findings scientifically proved the potential of medicinal plant extracts as anti-tumor compounds.  H. conica is the most potential one for further development as alternative drug for inhibited of tumor growth.

Abstract

he issue of air quality continues to be a major concern for both the environment and human health on a global scale, especially in developing nations. In 2015, Indonesia garnered international recognition as a result of the extensive forest and land fires. Exposure to PM particles in the air presents a substantial health hazard to individuals participating in their everyday routines. Research on the effects of forest fires on respiratory health in Central Kalimantan is still lacking. The Chest Miyagi multipurpose HI-801 spirometer, which was calibrated, was used to do lung function measurements. The participants were assessed while standing indoors in an environment with consistent air movement. Prior to the test, the individual's height and weight were measured and recorded in the spirometer, which then used this data to automatically determine the expected lung function. A sample size of 215 respondents who fulfilled the research criteria was selected for the study. The examinations took place in 7 urban and rural locations that were considered to be most susceptible to forest and land fires, based on the researcher's subjective judgment. These locations were chosen to meet the required sample size and were in close proximity to the fire sources. The spirometry device measures lung function, including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), the ratio of FEV1 to FVC, and Forced Expiratory Flow (FEF). This study aimed to assess the effect of recurrent forest fires on lung function, specifically in relation to gender, in Palangka Raya City, Pulang Pisau Regency, and Kapuas Regency, located in the Central Kalimantan Province. The analysis was conducted using spirometry tests. There were no notable disparities in lung function among the respondents based on their gender.
