Abstract: Changes of socio-economic and land use in the water catchment area are factors that affect the water quality of a lake. This study quantified the impact of socio-economic factors and the dynamics of land covers of Lake Toba water catchment area on the total suspended solid (TSS) parameter, one of the parameters in water quality indicators. Statistical analysis was run by using multiple linear regressions. Parameters observed were TSS, socioeconomic related data and land use in Samosir, Tobasa, Simalungun, Dairi, Humbang Hasundutan and North Tapanuli Regencies in 2008, 2012 and 2016. The results indicated that the water quality of Lake Toba was slightly polluted in 2016 and in 2017. Based on the regression analysis, it was found that some factors significantly affected the concentration of TSS, namely shrubland and dryland farming at 99% confidence level the number of populations, Location Quotient (LQ) for dry land paddy field and soybean production at 95% confidence level and settlement land area, geographic population density, LQ for rice and corn production at 90% confidence level. Managing shrubland through a land rehabilitation program and encouraging a rotational cropping system are recommended strategies to manage the increasing TSS in the Lake Toba.

Abstract: The management of natural resources based on socio-economic and ecology development has led to a focus on the bioeconomy in the policy discourse of non-timber forest products (NTFPs). Honey is an important NTFP with high socio-economic value, and its production involves millions of Indonesians. This article reviews the current status of honey-producing bee management, cultivation and harvesting system, marketing and socio-economic values, and the industry’s environmental function in Indonesia. This research utilized a meta-narrative review method to collect data and information from Google Scholar, Scopus, Science Direct, ResearchGate, Sinta, and Garuda. The study showed that the four bee species, namely Apis mellifera, Apis cerana, Apis dorsata, and stingless bee, are the most common species in honey production in Indonesia. The four species have specific characteristics based on habitat, production capacity, derivative products, management intervention to meet honey product standards, and sustainable livelihoods. The value chain of bees’ major products, such as honey, propolis, pollen, royal jelly, wax, and other derivative products, involves the distribution of honey to all involved communities, including beekeepers, honey gatherers/hunters, intermediate traders, and the processing industry. This study also found a significant association between environmental sustainability statutes that affects functional sustainability and economic function. The finding parallels the global trends that put forward a forest-based bioeconomy approach to forest resource management. The policy must be strengthened in managing relationships among supporting actors for sustainable honey production.

Abstract: ABSTRACTThe population growth rate in big cities such as Jakarta and its satellite cities has a correlation that is directly proportional to the level of clean water consumption. The biggest consumption of clean water is generally used for domestic household needs. However, the use of clean water is still not efficient. Therefore, the efficiency of water-saving needs to be carried out by utilizing sources that have not been optimally used, for ex le, greywater and rainwater. The purpose of this study is to determine the level of water usage in 3 (three) types of housing and the level of efficiency of utilization of domestic wastewater (greywater) and rainfall (CH) in reducing the use of clean water. This research was performed in the Villa Bintang Mas residential area in the City of South Tangerang, the Villa Bintang Mas residential area in the City of Depok, and the Selakopi Hijau/Forestry residential area in the City of Bogor. Data collection was conducted by a series of surveys using a questionnaire on the s le of a household. The results show that the data processing needs of clean water in three residentials range of values between ± 158.84 Liters erson/day up to ± 215.38 Liters erson/day. The level of efficiency of the utilization of greywater and rainwater in reducing the usage of clean water in three housing ranges from 21.12% to 58.47%.Keywords: Domestic Waste, the Use of Clean Water ABSTRAKTingkat pertumbuhan penduduk di kota-kota besar seperti jakarta dan kota-kota satelitnya memiliki korelasi yang berbanding lurus dengan tingkat konsumsi air bersih yang dimanfaatkan oleh masyarakat. Konsumsi air bersih terbesar adalah untuk kebutuhan domestik rumah tangga. Penggunaan air bersih saat ini masih belum mengikuti kaidah efisiensi dalam penggunaannya, untuk itu efisiensi penghematan air perlu segera dilakukan dengan memanfaatkan sumber-sumber lain yang belum termanfaatkan, antara lain air limbah domestik rumah tangga (grey water) dan air hujan. Tujuan dari penelitian ini adalah mengetahui tingkat pemakaian air di 3 (tiga) tipe perumahan,serta tingkat efisiensi pemanfaatan air limbah domestik rumah tangga (grey water) serta curah hujan (CH) dalam menurunkan pemakaian air bersih. Penelitian ini dilaksanakan di Perumahan Villa Bintang Mas, Kota Tangerang Selatan, Perumahan Permata Depok, Kota Depok, dan Perumahan Selakopi Hijau/Kehutanan, Kota Bogor. Pengambilan data dilakukan dengan cara survei menggunakan kuesioner pada rumah tangga yang menjadi s el. Hasil pengolahan data memperlihatkan bahwa kebutuhan air bersih di tiga perumahan berkisar pada rentang nilai antara ±158,84 Liter/Orang/Hari s ai dengan ± 215.38 Liter/Orang/Hari. Tingkat efisiensi pemanfaatan grey water dan air hujan dalam mengurangi pemakaian air bersih di tiga perumahan berkisar antara 21,12% hingga 58,47%.Kata kunci: Limbah Domestik, Penggunaan Air Bersih

Abstract: Kancilan Flores (Pachycephala nudigula nudigula) is an iconic bird of Kelimutu National Park. The bird has a unique characteristic with the ability to make a wide variety of song. The local people call this bird 'Garugiwa' and also 'burung arwah' or 'spirit bird' because it is small and hard to spot but has a loud chirp. Some literature mentions this bird with different scientific names. This study aimed to identify this bird to rectify this misnaming scientifically and to observes Kancilan Flores behavior, habitat, and population. Kancilan Flores is an attractive fauna for tourists. Therefore, this study also recommended potential birdwatching locations for Kancilan Flores. This study used a transect line and direct observation methods. The results showed that the estimated population size of Kancilan Flores in the Kelimutu National Park was 1,667 in iduals with a population size range of 1,245–2,089 in iduals. The population density of Kancilan Flores was estimated at 0.53 in iduals per hectare. The Kancilan Flores is most commonly found at an altitude of 1,500–1,600 m a.s.l. Recommended areas as bird watching locations for Kancilan Flores, namely the Edelweiss Garden, Perekonde, the lower Arboretum, and the Kancilan Flores middle Arboretum. Therefore, it is necessary to protect the population of Kancilan Flores by strictly prohibiting hunting and destruction of their habitat.

Abstract: Cratoxylum formosum (Jack) Benth. & Hook.f. ex Dyer is one of the plant species that have the potential to be developed into an antibacterial and antioxidant essential oil product. This study was conducted to determine the value of organoleptic tests and the consumers' willingness to pay (WTP) for the three variants of Cratoxylum formosum essential oil products. For the parameters of colour, hedonic test values and score tests showed good results panellists did not mind the pure and mixed Cratoxylum formosum essential oil colours. However, for fragrance parameters, the hedonic test showed a dislike score. Most panellists disliked the strong "scent of leaves" of pure C. formosum oil. The score test showed satisfactory values, the panellists accept the fragrance of Cratoxylum formosum essential oil, but it is necessary to add a more preferred scent mixture to reduce the strong original fragrance of the oil. The cost of production of Cratoxylum essential oil is Rp.7,259.23 (USD 0.48)/mL or Rp.72,592.30 (USD 4.84) for every 10 mL. Based on the cost ofproduction, the appropriate selling value for every 10 mL of Cratoxylum essential oil is a minimum of USD 4.84.

Abstract: Disposable plastic bags have already become global environmental problems due to their long durability. Plastic bags can be decomposed into microplastic and become more harmful to the environment. This paper will describe socio-economic factors that determinate plastic bag consumption and willingness to pay (WTP) for compostable shopping bags in Yogyakarta. Respondents were chosen using simple random s ling adopting Slovin formula. At a critical value of 4,82%, the s le size was 450 households. Socio-economic factors affecting the use of plastic bags are tested by employing multiple regressions. The result showed that the average use of plastic bags in Yogyakarta is 8 bags/household/week. Factors that influence the usage of plastic bags were the intensity of shopping in the supermarkets/grocery/convenience store, monthly shopping expenditure, and the intensity of the use of non-degradable plastic bags. WTP for compostable shopping bags is IDR 615 per bag. Since the traditional market was the first choice of respondents for daily or weekly shopping, plastic bag levy policy that applied in supermarkets has a limited impact on reducing plastic bag usage.

Abstract: Indonesia is the largest archipelagic country in the world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward from Sabang in Aceh to Merauke in Papua. Although occupying only 1.3% of the world’s land area, Indonesia possesses the third-largest rainforest and the second-highest level of bio ersity, with very high species ersity and endemism. However, during the last two decades, Indonesia has been known as a country with a high level of deforestation, a producer of smoke from burning forests and land, and a producer of carbon emissions. The aim of this paper is to review the environmental history and the long process of Indonesian forest management towards achieving environmental sustainability and community welfare. To do this, we analyze the milestones of Indonesian forest management history, present and future challenges, and provide strategic recommendations toward a viable Sustainable Forest Management (SFM) system. Our review showed that the history of forestry management in Indonesia has evolved through a long process, especially related to contestation over the control of natural resources and supporting policies and regulations. During the process, many efforts have been applied to reduce the deforestation rate, such as a moratorium on permitting primary natural forest and peat land, land rehabilitation and soil conservation, environmental protection, and other significant regulations. Therefore, these efforts should be maintained and improved continuously in the future due to their significant positive impacts on a variety of forest areas toward the achievement of viable SFM. Finally, we conclude that the Indonesian government has struggled to formulate sustainable forest management policies that balance economic, ecological, and social needs, among others, through developing and implementing social forestry instruments, developing and implementing human resource capacity, increasing community literacy, strengthening forest governance by eliminating ambiguity and overlapping regulations, simplification of bureaucracy, revitalization of traditional wisdom, and fair law enforcement.
