Abstract
Covid-19 has had an effect on various aspects of life. This study was to compare spatial distribution of covid-19 in Indonesia and Malaysia and its prevention efforts. The design of this study is a comparative study using descriptive analysis. Research was carry out in June through September 2020, taking location in Yogyakarta Special Region, Indonesia and Perak, Malaysia. Research focuses to data on infected positive patients with covid-19. Research data uses a secondary data, which is official statistics of covid-19. Statistical data then tabulated and mapping. The administrative map of both research sites used as a basis for the production spatial distribution map of positive patients infected with covid-19. Research shows that the number of positive patients infected by covid-19 June through September 2020 in five districts of Yogyakarta Special Region, Indonesia continued to increase significantly. Judging from time, spatial factors changes in covid-19 risk zones occurred in June to September 2020. Public movement and open access to Central Java Province causes 5 districts on Yogyakarta Special Region enter the high risk zone covid-19. Compared with Perak, Malaysia it different, spatially covid-19 infected number of positive patients in Perak, six district are relatively steady and four district are increasing. The increase occurred in Kinta District of July and August 2020, Kerian District of August 2020, Kuala Kangsar District of July 2020, and Perak Tengah District of September 2020. Judging from time, spatial factors do not changes the covid-19 risk zone from June to September 2020. Public movement and open access to Kedah, Kelantan, and Selangor caused two districts in Perak enter the high risk zone covid-19, five districts enter the medium risk zone covid-19, and three district enter the low risk zone covid-19. Indonesia and Malaysia's government efforts to prevent the spread of covid-19 are almost the same, which are restrictions on several public activities, clean and healthy socialization of living behaviour in all sectors, implementation of health discipline protocol in new normal, and provide of update covid-19 information data. The difference, lies in implementation lockdown, which some areas in Indonesia include Yogyakarta Special Region do not apply on Large Scale Social Restrictions (LSSR) like Jakarta, while a full implementation of lockdown in Malaysia through Movement Control Order (MCO) including Perak, so a growing number of covid-19 cases can be more pressure.

Abstract
Forest biodiversity is crucial for the survival of local communities in Mahakam Ulu District, East Kalimantan Province, Indonesia, especially for the Punan Dayak, Bahau Bateq Hwang Lung Gelawang, and Bakumpai Dayak tribes who live in the Ratah Watershed area. For generations, local communities in the Ratah Watershed have had local wisdom to protect the resources in the forest around them. Unfortunately, various problems threaten the existence of forest biodiversity in the Ratah Watershed. The purpose of this study is to show the identification results of the potential, utilization, and management of biodiversity according to local communities in Mahakam Ulu District, East Kalimantan Province, and the threats faced. The data was obtained through interviews with key informants, FGDs, participatory mapping, and field observations with the people of Nyari Bungan Village, Long Gelawang Village, Danum Paroy Village, and Muara Ratah Village. The result of the study indicated that local communities in the Ratah Watershed find it more inconvenient to utilize forest resources because of the diminishing potential for biodiversity. The low level of welfare, unclear village boundaries, overlapping village areas with private companies (timber companies, oil palm) are the main problems. Conservation of biodiversity from forests in the Ratah Watershed requires the cooperation of various parties, especially in increasing community capacity in managing forest resources for better environment.

Abstract
Timber in community forests can be utilized by the community by first removing it from the forest through the harvesting process. The harvesting process carried out has the potential for waste to be generated. This study aims to analyze the characteristics and potential of harvesting waste and develop alternative uses of waste into products that can be utilized by the community. Data were collected through field observations and making sample plots by purposive sampling on logging plots, skidding paths, plots on TPn, and plots on TPK. Analysis of the data used to determine the characteristics of the waste and its alternative uses, namely qualitative descriptive analysis and calculating the volume of waste using the Brereton empirical formula. The results showed that the characteristics of the wood waste found consisted of stump waste, branch-free stem waste with physical defects, twigs, short pieces, broken wood, and rotten wood. The potential logging waste that can be utilized is in the good category with an average volume of 1.56 m3 in the form of the stump, 2.85 m3 per log in the form of branch-free stems, and 2.45 m3 per log in the form of shortcuts. Alternative utilization of harvesting waste is based on the calculated characteristics and potential, waste can be used as firewood, waste with a diameter of 10 cm and above can be used as raw material for chips, boxes, and poles. Wood waste can also be utilized by the particleboard, fiberboard, finger-joint board, laminated board, pulp, and wood charcoal and charcoal briquette industries if the availability of raw waste materials is sustainable and in sufficient quantities.

AbstractEboni (Diospyros celebicaBakh.) is an endemic tree species of Sulawesi Island including Central Sulawesi, West Sulawesi and South Sulawesi. This species is also called fancy wood; its color is black-striped reddish brown, beautiful, and luxurious. In addition, tree growth is influenced by microbes, including fungi. Fungi are heterotrophic and eukaryotic organisms absorbing organic compounds from other organisms. The study aimed to identify ebony-associated fungi in Urban Forestry at the Tamalanrea Campus, Hasanuddin University, Makassar, Indonesia. This study consisted of the isolation stage both direct and dilution methods, the rejuvenation stage, and fungal identification. The study result indicated that there were 60 fungal isolates isolated from the ebony tree tissues, while 19 fungal isolates were isolated on the soil under the ebony stands. The direct isolation-based method was higher in term of number of fungal isolates than the dilution-based method. The isolated fungi belonged to the seven genera, namelyAspergillus, Penicillium, Gliocladium, Trichoderma, Fusarium, Rhizopus, andPhytophthora. AspergillusandPenicilliumwas genera dominated both in tree tissues and in the soil under ebony stands.

Published: November 2021

Abstract
There is a rising gap between supply and demand of wood as building and construction materials. The search of alternative materials to fill in the gap is an urgent concern. Bamboo is one of locally abundant resources; 88 out of 135 species growth in Indonesia is an endemic. It is a renewably material and has comparable characteristics to wood. Notable efforts to reduce the variability of raw bamboo have led to the improved physical and mechanical properties of the engineered bamboo. Laminated bamboo and hybrid laminated bamboo-wood had superior wood strength in comparison to the raw materials. Laminated bamboo produced from andong (Gigantochloa pseudoarundinacea (Steud.) Widjaja), mayan (Gigantochloa robusta Kurz), vertically laminated andong bamboo comparable to wood strength class I, I-II and II, respectively. Furthermore, hybrid laminated bamboo-wood andong-manii (Maesopsis eminii Engl.), andong-mayan-jabon (Anthocephalus cadamba (Roxb.) Miq.) comparable to wood strength class II and III, respectively. The properties improvement of engineered bamboo demonstrates the potential application of laminated bamboo as a substitution for building and construction material.

Abstract
One of the drying machines that is commonly used by in industry is a rack-type dryer. However, the rack-type drying machine has generally fairly low efficiency. A rack-type dryer has been designed which was equipped with a hybrid mechanism, but is its performance not yet known when it is controlled by an expert control system. The purpose of this research was to produce an expert control system that can be applied to a rack-type dryer with a hybrid system mechanism which can improve the performance of the dryer. The research includes the development of expert rules applied to the control system and a series of tests was carried out using 10 kg of fresh sago starch. The test results show that the drying air temperature did not show any overshoot and short settling time, drying temperature is relatively stable and there was no steady state error. The drying rate of fresh sago starch can be increased by using the hybrid system. The use of electric power with the hybrid system was lower (5.78 kWh) compared to that of non-hybrid (6.88 kWh) or a reduction of about 16% compared to the non-hybrid system. Thermal efficiency of the rack-type dryer with the expert control system was about 36%.

Abstract
People in Central Kalimantan province have long depended on the rivers around their villages. Yet, reports from the local health service show that the five diseases with the most patients are related to environmental factors, such as sanitation of water reservoirs and sanitation of home yards. This study aims to analyze the relationship between water quality, sanitation, and hygiene on environmental health in settlements on the banks of the Kahayan River. Data on sanitation, hygiene, and public health status were collected through observation and interviews, while river water quality was tested in the laboratory. The water to be analyzed was taken from three spots, namely upstream and downstream of the river, which are located out of the city, and the middle of river stream in the city centre. The results showed that the quality of water, sanitation, and hygiene in the city centre did not have a significant effect on environmental health even though the Environmental Heat Risk Assessment (EHRA) in the area showed poor scores. The study concludes that waste, as well as clean and healthy living behaviour is the biggest sanitation risks for environmental health. Synchronization of programs by related agencies could facilitate the arrangement of settlements on the riverbanks.

Abstract
A population estimation of proboscis monkeys (Nasalis larvatus) has been conducted in Manggar River, Balikpapan. In this non-conservation area, the anthropogenic activities threaten the proboscis monkey habitat. Boat survey technique was applied along ± 17 km of the river in the morning and evening. The number of proboscis monkeys in the surveyed area was estimated to range from 57 to 69 individuals with estimated population density of 4.75 individuals/Km2. Moreover, the population of this primates was divided into 4 groups and the sex ratio between adult males and females was 1:2.33. The proboscis monkeys were distributed in the middle of the river to the upstream. The highest population was found in the upstream area with less human activities. Conservation efforts in the Manggar River need to be carried out considering the proboscis monkey habitat in the area has been fragmented and isolated. These efforts could involve local economic communities.
