The Hibiscus macrophyllus tree is widely planted in Indonesia especially on Java Island. It has several advantages to be developed commercially as a community or plantation forest compared to the famous introduced species Falcataria moluccana and Anthocephalus spp., including faster growth, higher wood density, and better stem morphology (straighter, more rounded, and lesser branches). However, information about the basic properties of this wood grown in plantations is limited. This study aimed to investigate the anatomical properties of H. macrophyllus and their variation at three ages (8, 12 and 16 years old), as well as to predict the mature wood development by using radial variation in fiber length, microfibril angle (MFA), and wood density from pith toward the bark as the indicators. The wood samples were obtained from a community forest area at Ciamis Regency, West Java Province. Furthermore, anatomical characteristics were examined through wood slides following the IAWA List, while fibre and vessel element dimensions were measured through macerated specimens prepared by modified Franklin’s method. The MFA was determined by X-Ray Diffraction, while wood density was measured in line with British Standard 373-57. The results showed that the anatomical structures were not influenced by tree age, except for wood porosity, and fibre and vessel element dimensions. The 16-year-old tree tended to be semi-ring-porous, the younger trees were diffuse-porous, while the fiber and vessel element length, as well as the diameter, were decreased. Meanwhile, the wall thickness was increased. The fibre length, MFA, and wood density were useful indicators for wood maturity that seemed to be developed at about 11 years of age.

Global agreements mandate the international community, including Indonesia, to commit to reducing the risks and impacts of climate change. Indonesia’s Nationally Determined Contributions (NDCs) will contribute to the achievement of the Convention’s goals by reducing greenhouse gas (GHG) emissions and increasing climate resilience. This commitment must be supported by a wide range of actions, including the use of timber. Despite the fact that wood contains carbon, limited information is currently available on the size of the wood utilisation subsector’s contribution to reducing GHG emissions. More research is needed on the magnitude of wood products’ contribution to climate change mitigation. This study assessed the amount of carbon stored in wood used as a building material. Purposive sampling was used to select the cities with rapid housing development surrounding Jakarta’s capital city, i.e., the Bekasi District, East Jakarta City, Depok City, and Bogor District. The amount of carbon stored in wood was calculated according to EN 16449:2014-06 and energy dispersive X-ray spectroscopy (EDS/EDX) analysis. Results show that wood is currently only used in door frames, door leaves, window frames, shutters, and vents. The carbon stored on the components ranges from 450 to 680 kg (average of 554.50 kg) in each housing unit, according to the EN 16449:2014-06 calculation. The weight range is between 130 and 430 kg (average of 400.42 kg) according to EDX/S carbon analysis. With an increase in housing needs of 800,000 units per year, this amount has the potential to store 0.44 million tons of carbon over the lifespan of the products.

This article aims to show how to improve public services' capability and accessibility through e-government for villagers to reduce the rate of spread and infection of Covid-19 and as community participation in alternative ways of getting public services, Electronic Government (e-Gov) or digital government exists. Electronic government (e-Gov) itself provides information and public services, business affairs, services related to governance, et cetera by using information technology tools. However, the obstacles in this e-government-based public service are in applying the information system and the knowledge and access to information on this e-government-based public service. The digital divide is found in rural communities, often uninformed and reluctant to experience new technologies. Therefore, a community service program is needed, namely Improving Community Capability and Accessibility in Utilizing E-Government Public Services for villagers in the Middle of the COVID-19 Pandemic Outbreak in Semarang Regency.

The state has a preference right (priority) to collect tax debts on goods which belong to the taxpayer (debtor), meaning that the state's position as a preferred creditor is declared to have advance rights to the taxpayer's property to be auctioned in public. Preference rights by the State for paying off tax debts are in fact not as easy as imagined, there are disharmony in several laws and regulations, namely between the Taxation, Bankruptcy and Labor Laws and the Constitutional Court Verdict No.67/PUU-IX /2013 and other problems that affect the State's pre-emptive rights over paying tax debts. The objective of this study is to determine the impact of disharmony of Legal Regulations relating to Debt Repayment in Bankruptcy Against the State's Standing on Preferential Rights of Tax Debt. Based on research, the position of laborers' wages in Constitutional Court Decision No. 67/PUU-XI /2013 contrary to the provisions of the KPKPU Code which regulates labor wages as a bill of general preferred creditors and based on the principle of lex posteriori derogat legi priori, the position of laborers' wages in bankruptcy is based on the provisions of the KPKPU Code which overrides the provisions of Code No. 13 of 2013. Second, the consideration of the Constitutional Court on Verdict No. 67/PUU-XI/2013, is not in same direction with the provisions of the KPKPU Code which regulates that the wages of workers owed both before and after the bankruptcy was declared is a bankruptcy debt.

Doubtlessly, wood identification is critically important for a number of sectors, including government organizations, the wooden-based industry, museums, law enforcement, and scientists working in the fields of botany, ecology, forestry, and wood technology. Unfortunately, most wood species listed as “the least-known species” lack essential knowledge or even their anatomical feature and basic properties to promote their usage. This research aimed to investigate the anatomical characteristics and fiber quality of the least-known timber species of Apocynaceae family, which are authentic wood collection from Xylarium Bogoriense, namely  , Ervatamia. sphaerocarpa, E. aurantiaca, Kopsia flavida, Lepiniopsis ternatensis, Plumeria acuminata, P. rubra, and Voacanga foetida. Wood samples have indistinct growth ring boundaries, diffuse-porous vessels in diagonal and/or radial pattern, vessels in radial multiples of 4 or more cells, simple perforation plate, alternate intervessel pits; distinct borders of vessel-ray pits, similar with those of intervessel pits in size and shape throughout the ray cell, and septate fibers with simple pits to minutely bordered pits which are common in radial and tangential walls. Based on the fiber length and the derived values of fiber dimension, some species are classified into Quality Class II and III, and the rest of them are classified into Quality Class II or III for pulp and paper manufacturing. Based on general characteristics, commonly Apocynaceae can be used as handicrafts raw material. Based on the fiber quality, some species which are classified into Quality Class II, are predicted to have potential as pulp and paper material with medium quality.
