This study aims to conduct a study of the quality value of briquettes made from mixing straw and rice husks which include a flame test and combustion rate which is expected to be used to educate people around the forest by providing innovation and technology regarding the use of post-harvest waste. The results showed that the value of the quality of briquettes made from variations in the mixing of straw and rice husks including the flame test of the combustion rate obtained results, for treatment A (100% straw) of 0.68 gr/minute, treatment B (100% husk) of 0 ,57 gr/minute, treatment C (Husk 75% + Straw 25%) was 0.40 gr/minute, treatment D (Husk 25% + Straw 75%) was 0.46 r/minute and treatment E (Husk 50% + Straw 50%) of 0.43 gr/minute. The value of the flame to boiling time for treatment A = 38.62 minutes, treatment B = 31.05, treatment C = 23.22 minutes, treatment D = 36.05 and treatment E = 27.95 minutes. Density values of all treatments, and the water content for treatment B and treatment C can meet SII. While other parameters: ash content, volatile matter, bound carbon and calorific value still cannot meet the standards, so it is recommended to carry out further research with other variations of treatment, in order to obtain briquettes with quality that can meet the standards.

Open mining activities have caused soil damage, water pollution, air pollution, and damage to vegetation. Limestone post mining is a critical area that must be rehabilitated to be productive again. This problems can be fixed by doing land reclamation activities which mandated in the Mining Law Number 4, 2009. The success of land reclamation is largely determined by the choice of plant species and the provision of appropriate soil enhancers (ameliorant). This study was aimed to analyze the growth response of sengon plants on giving ameliorant in mixed limestone post mining soil. This study was designed in completely randomized design for 7 treatments and 3 replications used combination of ameliorant: P0 (without ameliorant); P1 (AH 4 kg ha-1); P2 (BFA 350 kg ha-1); P3 (FMA 500 spores plant-1); P4 (the combination of AH and FMA); P5 (the combination of BFA and FMA); and P6 (the combination of AH, BFA, and FMA). Data were processed by analysis of variance at the 0,05 significance level followed by the Least Significant Difference test. The results showed that the best growth response of sengon on giving ameliorant in mixed limestone post mining soil was P1 treatment (humic acid material) which significantly increased root length, root volume, root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight in sengon plants. The addition of ameliorant can be recommended to improve the quality of revegetation plants
露天采矿活动造成了土壤破坏、水污染、空气污染和植被破坏。石灰石后期开采是一个必须恢复生产的关键领域。这个问题可以通过2009年第4号矿业法规定的土地复垦活动来解决。土地复垦的成功在很大程度上取决于植物种类的选择和提供适当的土壤增强剂(改良剂)。本研究旨在分析在混合石灰石采煤后土壤中施用改良剂对桑根植物生长的响应。本研究采用完全随机设计，7个处理，3个重复，使用改良剂组合:P0(无改良剂);P1 (AH 4 kg ha-1);P2 (BFA 350 kg ha-1);P3 (FMA 500孢子植物-1);P4 (AH与FMA的结合);P5 (BFA和FMA的组合);P6 (AH、BFA、FMA的组合)。数据在0.05显著性水平上进行方差分析，然后进行最小显著性差异检验。结果表明，在采煤后混合石灰岩土壤中，施改良剂P1(腐植酸物质)处理对仙根的生长响应最好，显著提高了仙根的根长、根体积、根鲜重、茎鲜重、根干重和茎干重。建议通过添加改良剂来提高植被质量

Limestone post mining is a critical area that must be rehabilitated to be productive again. This problems can be fixed by doing land reclamation activities which mandated in the Mining Law Number 4, 2009. The success of land reclamation is largely determined by the choice of plant species and the provision of appropriate soil enhancers (ameliorant). This study was aimed to analyze the growth response of sengon plants on giving ameliorant in mixed limestone post mining soil. This study was designed in completely randomized design for 7 treatments and 3 replications used combination of ameliorant: P0 (without ameliorant); P1 (AH 4 kg ha-1); P2 (BFA 350 kg ha-1); P3 (FMA 500 spores plant-1); P4 (the combination of AH and FMA); P5 (the combination of BFA and FMA); and P6 (the combination of AH, BFA, and FMA). Data were processed by analysis of variance at the 0,05 significance level followed by the Least Significant Difference test. The results showed that the best growth response of sengon on giving ameliorant in mixed limestone post mining soil was P1 treatment (humic acid material) which significantly increased root length, root volume, root fresh weight, shoot fresh weight, root dry weight, and shoot dry weight in sengon plants. The addition of ameliorant can be recommended to improve the quality of revegetation plants","PeriodicalId":17696,"journal":{"name":"Jurnal Hutan Tropis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47769250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The condition of mangrove forests on the east coast of East Lampung Regency is currently experiencing degradation and has suffered a lot of damage due to various causes and problems it faces. This condition causes the role and benefits and functions of mangrove forests to decrease, especially in climate change. Therefore, to determine the condition of the mangrove forest, periodic monitoring and assessment of mangrove forest health is required. The purpose of this study was to determine the importance of mangrove forest health in climate change. To achieve this, the stages include: determining the number of plot clusters to be made, making cluster plots, measuring the health of mangrove forests based on ecological indicators of mangrove forest health, processing and analyzing mangrove forest health data using SIPUT (Assessment Information System) software. Forest Health), and categorization and health assessment of mangrove forests. The results of this study indicate that the condition of mangrove forests on the East coast of East Lampung Regency in general has a forest health condition in the medium category. So, knowing the health condition of mangrove forests will affect climate change. Forest health makes mangrove plants grow with good physiological processes so that they can absorb carbon dioxide in the atmosphere optimally. These conditions will make the environment better.
