HUBUNGAN ANTARA TITIK DIDIH DENGAN PERSENTASE MASSA DARI BEBERAPA LARUTAN MADU ALAMI DAN MADU KOMERSIAL
No full textThe traditional society's need for natural honey cannot easily be met with the many alternatives to commercial honey today,but the consistency of traditional methods in determining the authenticity of natural honey has not been scientifically confirmed. Thissimple research aims to study the relationship between the boiling point and mass percentage of some dilute natural honey based onthe basic idea of the colligative properties of the solution and its comparison with some commercial honey samples. Each honeysample (six samples of natural honey and six samples of commercial honey) was diluted with distilled water in various weightpercentages of 2.5–15.0% (w/w), then the boiling points were determined in ambient temperature and pressure. By using polynomialregression of degree 3, it was found that all-natural honey solutions had a pattern of increasing boiling point with increasing weightpercentage, with different curvature patterns approaching linear (R3Lin), logarithmic (R3Log), exponential (R3Exp), and sigmoid(R3Sig) like patterns. The results of the comparison with six commercial honey solutions, there are only two samples that have anincreasing regularity pattern, the rest are like fluctuates and/or has no relationship. Based on these results, the natural honeysolution still has a close consistency with the colligative properties of the concentrated solutions so that it can be recommended as anew method in determining the authenticity of honey that has not undergone further processing, remains simple, easy, and inexpensivefor testing
PENGARUH KADAR AIR TERHADAP KUALITAS PELET KAYU DARI SERBUK GERGAJIAN KAYU JABON DAN KETAPANG
No full textIn the last few years, wood pellet demand has increased globally for residential purposes. In term of standard quality, wood pellet for residential purposes are tighter than industrial purposes. The wood pellet quality parameters are moisture changes in biomass, impacts on bulk density, and mechanical durability. This paper analyzes the effect of biomass moisture content (MC) into the quality of wood pellet made from jabon and ketapang sawdust to meet quality standard of ISO 17225-2. The pellet was grouped into three, based on MCs, i.e. <10% (air-dry), 15% and 20%. The sawdust was then pressed at 464.52 kg/cm2, 150°C for 10 minutes. Analysis of variance (ANOVA) was conducted by Tukey and Homogenity tests on results. The optimum wood pellet quality was assessed using scoring requirement for residential use with less smoke and combustion residue
KEAWETAN LIMA PULUH JENIS KAYU TERHADAP UJI KUBURAN DAN UJI DI LAUT
No full textFifty wood species collected from Indonesian forest regions were tested according to graveyard test standard and sea water exposure. Wood samples with dimensions of 60 x 5 x 5 em were prepared for graveyard test in Cikampek and 30 x 5 x 2.5 cm for sea water exposure in Rambut Island test area. The results show that in general wood species tested are susceptible to termite attack. Forty seven wood species out of 50 species tested (94%) were positively attacked by termites. Twenty eight species (56%) are classified into natural durability class V, 15 species (14%) are classified into natural durability class IV and 7 species are classified into natural durability class III. One species, Blumeodendron tundifolium was attacked not only bry termite but also suffers by decaying fungi.
Another 5 species: Erythrina fusca, Litsea roxburghii, Myristica subaculata, Stercularia oblongata and Trichodenia phillipinensis were also attacked by termites and fungus simultaneously. Sea water exposure test shows that almost all wood species tested were attacked by marine borers. Four wood species (8%) are moderately resistant and classified as natural durability class II, and 12 species (24%) are not resistant and classified as natural durability class IV, while 50 wood species (64%) are classified as perishable and classified as durability class V against marine borers. Only two wood species: Azadirachta indica and Parinari corymbosa arv dassified as durability class II. Marine borers attacked the wood samples include: Martesia striata (Pholadidar family). Teredo bartschi. Dicyathifer manni and Bankia ceba (Teedinidae family)
KOMPONEN KIMIA ORGANIK LIMA JENIS ASAP CAIR
No full textPlants such as cacao (Theobroma cacao), avocado (Persea americana), puspa (Schima wallichii), sengon(Falcataria mollucana) and tarik angin (Usnea sp.) are widely planted in the community for fruit or wood needs.Periodically, they harvest these types of wood for common uses or plant rotation purposes. In general, wood sorting is usedfor simple construction or even conventionally burned. In addition to conventional combustion techniques to produce charcoal,there is another product that can be produced, namely liquid smoke - using a combustion technique by adding a condenserto produce liquid smoke. Liquid smoke contains organic chemicals with various benefits. This study investigates the organicchemical content of liquid smoke of cacao, avocado, puspa, sengon, and tarik angin wood. The five types of materialswere carbonized using a pyrolysis reactor around 400oC. Liquid smoke was obtained by condensing fumes mechanism.Analysis of organic liquid chemical using Gas Chromatography Mass Spectrometer (GCMS) Pirolisys Type QP2010and High Performance Liquid Chromatography (HPLC). GCMS analysis showed that cacao liquid smoke has thehighest concentration of acidic group, of the 45.53%, where the concentration of acetic acid was 31.81%. The presence ofthe highest phenol group was in avocado liquid smoke as much as 56.86%, where the concentration of phenol compoundsreached 41.92%. The acid and phenol groups are type of compounds contained in liquid smoke and have a lot of benefits
Government-Corporate Cooperation and Community Participation in Boosting Indonesia Green Economy
No full textEnvironmental issues are currently interesting discussion, especially for developing countries. This condition is inseparable from the economic policies of developed countries which have begun to apply the concept of a green economy. Indonesia is still pursuing economic growth to the exclusion of environmental factors. However, the government is trying to overcome environmental problems through green growth policies. The government cannot do it alone, synergy with business actors is needed to create a green economy. The data used in the quantitative method is sourced from BPS environmental statistics for 2013-2020, and Bank Indonesia quarterly 2019-2020 regional financial statistics. The results show that the implementation of greening the national economy has been going well by the government. Corporate through applied ESG like CSR, and community development, and green business principles. It was found that the support from the community has not been maximized because of the ineffectiveness of education related to the importance of the environment for future generations. Massive education is needed through an education system to the community and the provision of rewards (incentives & tax relaxing) for companies ultimately Indonesia's economy and environment are green
The Effect Of Parents' Informality And Poverty On Child Labor Decisions In Indonesia
No full textChild labor is a type of work that must be eliminated to achieve decent work. Child labor is still a global problem, including in Indonesia. The causes of child labor are closely related to family factors, namely parents' work and poverty. Therefore, this study aims to analyze the effect of informality and poverty on child labor in Indonesia using data from the 2021 National Socio-Economic Survey. The method used is multinomial logit regression analysis with work, work-school, and school categories in children aged 10-17. The analysis results show that the relative opportunity for children to work and work while attending school compared to school is higher for households with a head of household working in the informal sector compared to the formal sector. Poverty has a different pattern where the relative opportunity for children to work compared to school is higher in poor households than in non-poor. However, the relative probability of a child working while attending school is lower for poor households than for non-poor households. Policies related to parental informality and poverty can be intensified to reduce child labor in Indonesia.
 
Does Green Finance, Digitalization, and Energy Intensity Help the Path to SDGS? : New Insight from Selected Emerging Market Countries
No full textThe issue of climate change has always been a highlight for ecologists and leaders of various countries. This context is a complement to the study of the concept of sustainable development to preserve the environment. On the other hand, carbon emissions are the main cause of global warming and result in environmental degradation, thus requiring mitigation to achieve inclusive, sustainable development. Therefore, this study investigates the impact of green finance, digitalization, and energy intensity on carbon emissions in 18 emerging market countries during 1992–2022. This study uses a dynamic heterogeneous panel approach (panel autoregressive distributed lag model-panel ARDL) pooled mean group (PMG). The study results indicate that green finance has a positive but insignificant effect in the long term but has a short-term effect on carbon emissions. Digitalization has a significant positive effect in the long term but a significant negative effect on carbon emissions. Meanwhile, energy intention has a significant positive effect in the long term and a significant positive effect in the short term on carbon emissions in emerging market countries during the study period. These findings provide new insights into the role of these three indicators to be considered in contributing to and supporting sustainable environmental development globally and specifically in emerging market countries.
Dampak Kepemilikan Lahan Pertanian Terhadap Subjective Wellbeing Petani di Indonesia
No full textWelfare measures has shifted to the condition of subjective wellbeing (SWB). Meanwhile, the welfare of
farmers must be prioritized, one of which is to fulfill their basic needs in the form of agricultural land. Ironically,
land ownership inequality in Indonesia is still quite high. This study aims to see the impact of agricultural land
ownership on the SWB score of farmers in Indonesia. This study uses data from the 2007 and 2014 IFLS and
fixed effect estimation method and PSM to address selection bias. Agricultural land tenure was found to have a
consistent and positive effect on SWB even after controlling for income
Covid-19 Case: Does Indonesian Need Health Endowment Fund?
No full textThis paper examines whether Indonesia needs a Health Endowment Fund (HEF) to find the efficiency and
effectiveness of the health cover fund. Since 2014, Indonesia has officially implemented the National Health
Insurance (NHI or Jaminan Kesehatan Nasional/JKN) according to Law No.40/2004. The implementation of NHI
is technically managed by Health Social Insurance Administration Organization (HSIAO), also known as
Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan. Since 2014, the trend of people living with non-communicable
diseases (NCDs) hasincreased between 2007and 2014. This trend may lead to future consequences of potential fin ancial deficits for HSIAO. Furthermore, many countries,including Indonesia, have been facing fiscal shock due to recessions from the COVID-19 pandemic and increasing deficits from health insurance claims. By employing secondary data IFLS4, IFLS5, and BRIN survey data in 2020, this study investigates the effect of NCDs on household expenditures to assess the need for HEF in Indonesia. Using regression analysis, the result showed that NCD was associated with household’s per capita expenditure and access to health care. Moreover, NCDs harm subjective health status. Therefore, HEF may be a long-term solution for the financial burdenthat HSIAO
may face mitigating fiscal shock for the government budget
