Abstract

Adsorbent is a solid substance that can absorb certain components from a fluid phase. Adsorbents consist of materials that are porous and directly hit the pore walls at a pertical location. The purpose of this final project is to see whether the purification of used cooking oil with the adsorbent method using a mixture of corn husk and shrimp shell chitosan adsorbents in several comparisons has an effect in purifying used cooking oil. This research was conducted by adsorption method of used cooking oil samples using corn husk bioadsorbent and shrimp shell chitosan. The use of this used cooking oil adsorbent process is so that used cooking oil that is no longer suitable for use in the community can be reused. Then proceed with the adsorption process starting with 100 ml of oil added 5 g of adsorbent with variations in the mass ratio of chitosan and corn husk = ((25: 75), (50: 50), and (75:25)%) stirring constantly for 90 minutes with temperature 70-80 C. The best results based on SNI cooking oil are in a ratio of 3,5 g: 1,5 g to 5 grams of adsorbent used or at a ratio of 75% corn husk adsorbent: 25% shrimp shell chitosan, with an acid number of 0,62 mg KOH /g, the free fatty acid compound is 0,80% and the peroxide number is 6,36 meq 02/kg.

Abstract

Sungkai Peronema canescens is well known as a medicinal plant at Central Kalimantan. Indiginous people of Dayak and Banjar tribes who are living in East Kotawaringin Regency consume Sungkai plant into traditional medicine. The potential use of sungkai as medicine was identified from three selected villages of East Kotawaringin Regency namely Bagendang Permai, Bagendang Hulu and Bagendang Hilir. Ethnomedicine of sungkai leaves was investigated using a semi structured questionnaire technique and 180 respondents were selected by a purposive sampling. The interviewees were divided into gender and four groups based on their ages to identify knowledge level in using sungkai leaves as a medicinal plant. Their knowledge was analyzed based on gender and ages using Kruskal Wallis test and then Mann Whitney U-test was used to decide the difference of knowledge level. The results showed leaves are the main part to be utilized as medicine. Leaves were preferably boiled by respondents to increase their immune system and to cure fever and some used for puerperal mother bath mixture. The indiginous knowledge level was 82.57 categorized as a high knowledge level. Moreover, both gender and ages had no difference knowledge level on using sungkai as medicine.

Abstract

The assessment of the success rate of reclamation uses a reference assessment of PERMENHUT 60 of 2009 with scoring of three criteria, namely: Land arrangement with a score of 30%, control of erosion and sedimentation with a score of 20%, and revegetation with a score of 50%. The reclamation success rate assessment result based on the total score is both >80, medium 60-80, and ugly <60. The implementation of reclamation of mining business permits based on the calculation of the total value obtained a value of 48.5 which shows that the reclamation results are included in the ugly criteria (reclamation results are unacceptable and intensive maintenance is needed), so it is necessary to carry out reclamation repairs. The reclamation criteria that received a less assessment was the implementation of revegetation which had the lowest value, namely, 14 out of 50 weights and erosion and sedimentation control had a value of 12 out of 20, while land management had a value of 22.5 out of a weight of 30. Activities that can be carried out to improve reclamation on former mining business permit land are land management, reducing landslides, erosion, and sedimentation, improving the quality of physical and chemical soil properties with regular fertilization and liming, spraying pesticides, cleaning cover crop windings on plants periodically carried out, reselecting cover crops, selecting sengon plants as pioneer plants, selection of jackfruit plants as local insert crops, then the commitment of policymakers in the implementation of reclamation, fulfillment of labor competencies, remaking of erosion and sedimentation control facilities, and providing facilities and infrastructure for breeding diverse plants.

Abstract

In line with the increasing population and the community's need for city facilities and infrastructure, urban development continues to increase. The paradigm of urban development should have changed and needs to be designed early towards the city with a better, more balanced way of life and still paying attention to environmental quality. The level of environmental comfort decreases as a result of the imbalance between built-up space and green open space (RTH) with the three main functions of urban vegetation being structural function, environmental function and visual function. RTH has a role in shaping the comfort of the urban climate through ecological functions, namely as a regulator of air temperature and humidity, so that it can be used as input in improving the quality of the microclimate by improving the quality of urban RTH so as to minimize the decline in environmental quality. The purpose of the study was to analyze the influence of vegetation structure and the role in improving the microclimate at each Tropical Rainforest Miniature RTH location in the Governor's Office area in Banjarbaru City. Banua Botanical Garden as a research site located in the Banjarbaru City Area, South Kalimantan Provincial Government Office Complex. The influence of vegetation structure on Location I which is dominated by lawns/grasses and shrubs with horizontal and columnar header shapes with low header density. Meanwhile, in Location II, the shape of the canopy is columnar and horizontal with a medium canopy density and has a tree height of 3-4 meters, slightly reducing the air temperature around the RTH. For Locations III and IV, they have a pyramid-shaped and spherical header shape that acts as a counterweight to increasing air humidity and decreasing air temperature.  The role of the Tropical Rainforest Miniature RTH in the Governor's Office area in Banjarbaru City in improving the microclimate based on air temperature at locations I, II, III and IV, namely 30.1°C, 29.2°C, 28.0°C and 27.3°C.  It can be seen that location III and location IV have the lowest temperature because they have characteristics of vegetation structures that can lower air temperature. For humidity parameters, it will adjust to air temperature conditions as well as wind speed will adjust to the vegetation structure in the RTH.

Abstract

The mining and plantation sector has a vital role in increasing GRDP and provides a positive multiplier effect on output, added value, income, and labor. However, on the other hand, it also has a negative impact on increasing environmental damage and climate change, resulting in flood disasters in almost all areas of South Kalimantan. Disaster mitigation planning is the main key to disaster management. This research compiles a post-flood management plan, especially in Karang Intan Sub-district. This research is quantitative research. The method used is a spatial analysis by overlaying the flood water level with objects in it such as houses, roads, and people. Objects that are vulnerable to flooding are those located at flood water levels above class 2 (TMA=0.1-0.5 meters). The number of houses that are vulnerable to being affected is 2,107 units, consisting of 697 units of safe flood conditions, 170 units of safe enough, and 1,239 units of vulnerable. Based on this, the evacuation point was determined as many as 23 points with the most evacuation point coverage, namely evacuation point number 22, which can reach 340 houses in Sungai Alang Village.

Abstract

The river found in Samarinda City is the Karang Mumus River. This river is a tributary of the Mahakam River which divides Samarinda City in East Kalimantan. The polluting source of the Karang Mumus River comes from domestic activities such as settlements, markets, shopping centers, and hotels. The purpose of this study is to determine the water quality of the Karang Mumus river in terms of predetermined parameters, namely nitrites, nitrates and phosphates in waters. This type of research is a descriptive study with a qualitative approach to see the concentration of nitrite, nitrate, and phosphate parameters in the water of the Karang Mumus River from Upstream to Downstream. The results showed that the highest nitrite value based on eight segments was in segment 3 is 0.026 mg/L. The lowest value of nitrite was in segment 8 with a concentration of 0.0095 mg/L. Based on PerDa KalTim No. 02 of 2011 class II nitrite value in all segments is still meet the quality standard of 0.06 mg/L. The highest concentration of nitrate is upstream, in segment 2 with a concentration of 0.155 mg/L. Lowest nitrate concentration is in the middle of segment 5, which is 0.069 mg/L.

Abstract

This study aims to analyze land suitability in reclamation and revegetation sites for sengon, trembesi, mahogany and acacia plants. Research was conducted in November 2022 at PT Adaro Indonesia Site Tanjung, South Kalimantan Province. Data collection was in the form of analysis of soil quality in the reclamation areas of Wara 1, Wara 2, Wara 3 and Wara 4 and data on land characteristics as a condition for growing sengon, acacia, trembesi and mahogany plants, then a matching method was carried out to obtain land suitability for these plant types. The results showed that the actual land suitability for sengon plants in the entire study area was incompatible with the inhibiting factors for nutrient retention and quite compatible with the inhibiting factors for water availability (S3nr.S2wa) and the potential land suitability was S2nr. Land suitability for acacia plants in all study areas found land that was not suitable for nutrient retention inhibiting factors (S3nr) and potential land suitability was S2nr. Land suitability for trembesi plants in Wara 1 and Wara 2 obtained land yields that were not in accordance with the nutrient retention inhibiting factor (S3nr) and S2nr potential land suitability, while in the Wara 3 and Wara 4 areas suitable land yields were obtained without any limiting factors. Land suitability for mahogany plants in all study areas found land that was not suitable for the limiting factor of nutrient retention and quite suitable for the limiting factor for water availability (S3nr.S2wa).
