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 individuals with a population size range of 1,245–2,089 individuals. The population density of Kancilan Flores was estimated at 0.53 individuals 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

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 example, 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 sample of a household. The results show that the data processing needs of clean water in three residentials range of values between ± 158.84 Liters/person/day up to ± 215.38 Liters/person/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.

Abstract

ABSTRACTPopulation growth in major cities in Indonesia has implications to the increase of clean water consumption. The highest demand of clean water is in fulfilling household needs. The use of clean water for household needs does not follow the efficiency principle. So that in fulfilling the water needs, it is necessary to use other sources, one of which is grey water. This study aims to determine the effectiveness of multimedia contacts by adding wood shavings as biofilter material in treating grey water. The applied method in this research is quantitative with a qualitative descriptive approach, by conducting experiments using wood shavings as a material for biofilter. This research was carried out in the residential of Villa Bintang Mas, South Tangerang City in October 2018. The results showed that the usage of biofilter materials with the addition of wood shavings was effective in removing the pollutant of the grey water. It is indicated by the level of biofilter efficiency in reducing pollutant concentrations ranging from 40.6% (BOD parameters) to 100% (Coliform parameters). Nevertheless, Coliform parameters still do not meet the standard quality, therefore, there is a need for additional disinfectants to reduce Coliform levels.Keywords: grey water; biofilter; wood shavings; multimedia ABSTRAKPertumbuhan penduduk pada kota-kota besar di Indonesia berimplikasi pada peningkatan konsumsi air bersih. Konsumsi air bersih terbesar salah satunya dalam pemenuhan kebutuhan domestik rumah tangga. Penggunaan air bersih untuk kebutuhan domestik saat ini masih belum mengikuti kaidah efisiensi dalam penggunaannya. Oleh karena itu, dalam pemenuhan kebutuhan air tersebut perlu dilakukan pemanfaatan sumber lainnya, salah satunya adalah air sisa limbah domestik rumah tangga (grey water).

Abstract

Currently, incentive payment of carbon mechanism has not yet provided significant economic benefit for community who live in the surrounding forest area as the carbon price is relatively low. Consequently, potential carbon owners are likely to invest conserved carbon biomass into other products that give more profitable economic value.  This paper discusses the estimation of feasible carbon selling price of Sekaroh Protection Forest based on analysis of the forest economic value approach. This study was conducted  using descriptive quantitative method based on primary data sources of the Afforestation/Reforestation (A/R) Clean Development Mechanism (CDM) implementation in 2010–2013 at Sekaroh. Research results showed that based on the calculation of annual economic value (AEV), the economic value is estimated about Rp73,394,816.00 per hectare per year at the  interest rate of 5.75%. Hence, a reasonable carbon price based on the economic value is US$23 per ton carbon. This estimated value is significantly greater than the current prevailing carbon price that is US$4.6–10 per ton carbon. Higher reasonable carbon price will attract community around the forest to keep their biomass carbon stocks in the forest, so that future business of carbon trade mechanism can be more interesting and runs better.

Abstract

Konsentrasi timbel (Pb) yang tinggi di udara, khususnya di sekitar pabrik peleburan aki bekas berisiko bagi kesehatan manusia. Tumbuhan mempunyai fungsi filtrasi terhadap polutan udara sehingga udara yang dihasilkan menjadi lebih segar. Peran tumbuhan dalam penyerapan timbel di lokasi sekitar peleburan aki bekas belum banyak dikaji. Penelitian ini bertujuan mengidentifikasi karakteristik konsentrasi timbel dalam daun di sekitar pabrik peleburan aki bekas di kawasan industri Kadu Manis Tangerang dan kawasan industri Jababeka Bekasi. Penelitian ini adalah penelitian kuantitatif, sampel yang diambil merupakan daun pada pohon yang berada di sekitar kawasan industri Kadu Manis Tangerang dan kawasan industri Jababeka Bekasi. Sampel daun diambil sesuai arah mata angin dengan jenis pohon yang diambil adalah Trembesi (Samanea saman), Bintaro (Cerbera manghas), dan Glodokan (Polyalthia longifolia). Sampel daun diambil dalam radius 0 hingga 7,5 km dari lokasi peleburan aki bekas. Konsentrasi timbel dalam daun dihitung dengan menggunakan AAS (Atomic Absorption Spectrophotometry). Analisis data dilakukan dengan menggunakan regresi linear berganda.  Hasil penelitian menunjukkan bahwa arah angin berpengaruh nyata terhadap konsentrasi timbel dalam daun. Pepohonan yang berada di sebelah utara pabrik peleburan mempunyai kadar timbel paling besar dibanding tiga arah lainnya. Jarak dengan peleburan aki bekas hanya berpengaruh nyata terhadap konsentrasi timbel di kawasan industri Jababeka Bekasi.ABSTRACTThe high concentration of lead (Pb) in the air, especially around the smelter of used batteries is harmful for human health. Plants have a good filtration function for air pollutants. Effect of plants in the absorption of lead in the air, especially in locations around the smelting of used batteries has not been widely studied. This study aims to identify the characteristics of lead concentration in leaves around the smelter in industrial area of Kadu Manis, Tangerang and industrial area of Jababeka, Bekasi. This research is quantitative research, samples taken are leaves on trees that are around the smelters. Leaf samples were taken following the direction of the wind, with the tree species taken were Trembesi (Samanea saman), Bintaro (Cerbera manghas), and Glodokan (Polyalthia longifolia). Samples were taken in a radius of 0 to 7.5 km from the smelters. The lead concentration was analyzed using AAS (Atomic Absorption Spectrophotometry). Data analysis was performed using multiple linear regression. Wind direction has a significant effect on lead concentration in leaves. Trees that are north of the smelter have the highest lead levels compared to the other three directions. The distance with lead smelting only has a significant effect on lead concentration in Jababeka Industries.

Abstract

Perubahan iklim (climate change) yang terjadi saat ini merupakan akibat meningkatnya emisi CO2. Konsumsi energi dan pertumbuhan ekonomi sebagai penggerak perekonomian dianggap paling berpengaruh terhadap meningkatnya emisi CO2. Nilai hutan sebagai penyerap emisi CO2 hingga saat ini belum banyak diketahui. Maka diperlukan suatu riset empiris untuk mengetahui pengaruh konsumsi energi, pertumbuhan ekonomi, serta variabel baru berupa luas kawasan hutan yang turun terhadap peningkatan emisi CO2 di 6 (enam) negara-negara anggota ASEAN. Penelitian ini bersifat desk analysis dengan metode pengumpulan data yang digunakan adalah metode kepustakaan. Pembahasan analisis yang digunakan adalah analisis estimasi model ekonometrik dan statistika menurut panel data regression. Hasil penelitian menunjukkan bahwa model ekonometrika dari variabel konsumsi energi, pertumbuhan ekonomi dengan menambahkan variabel luas kawasan hutan mempunyai pengaruh terhadap emisi CO2 dengan tingkat kepercayaan terhadap model sebesar 97,84% dan sisanya yaitu 2,16% dipengaruhi oleh variabel-variabel lain diluar varibel tersebut. Indikasinya setiap kenaikan satu persen luasan hutan dari suatu negara akan mampu menurunkan nilai emisi CO2 sebesar 0,04% (dalam metrik ton per kapita).

Abstract

Batak Toba community who live in the surrounding forests utilise forest-fruits that grow around their settlement.  This research aims to describe the important value of  the forest fruits using the Local Users Value Index (LUVI) assessment as most of  the fruits have not yet been traded.  The research was conducted in Simardangiang and Sitoluama Villages in North Tapanuli Regency, 2015. Data collection was done by interviewing 65 respondents selected purposively based on gender and age classification. The results showed that there were 29 species of  forest fruits utilised by the community. They were categorised into four utilisation types: fresh fruit, flavouring fruit, processed fruit, and medicines.  In Simardangiang Village, the five most important fruits were kapundung or menteng (Baccaurea racemose) (0.56), hopong (Macaranga lowii) (0.52), sotul, santol or sentul (Sandoricum koetjape) (0.48), harimonting or kemunting (Rhodomyrtus tomentosa) (0.47), and habo or kabau (Archidendron bubalinum) (0.42). Meanwhile, in Sitoluama Village, the five most important fruits were kapundung (Baccaurea racemosa) (0.50), hopong (Macaranga lowii) (0.41), sihim or rotan manau (Calamus manan) (0.32), handis or gamboge (Garcinia xanthochymus) (0.32), and mobe (Artocarpus dadah) (0.19). The numbers in parentheses are the important value based on LUVI. The forest fruits that have domestication potency are kapundung (Baccaurea racemose), hopong (Macaranga Iowii), sihim (Calamus manan), handis (Garcinia xanthochymus), mobe (Artocarpus dadah), harimonting (Rhodomyrtus tomentosa), sotul (Sandorium koetjape) and habo (Archidendron bubalinum).
