Abstract

This paper identifies the plant species used  traditionally by Karo people in North Sumatra, to cure diabetes, analyses the cultural significance index of those plants for the Karo, and clarifies phytochemical contents of the plants. Data were collected using survey method from selected respondents (n=54) based on their knowledge and practices in utilising medicinal plants to cure diabetic disease. Index of Cultural Significance (ICS) of plants was determined using the method proposed by Turner. Results showed that twelve woody plant species have been used to cure diabetes: loning leave (Psychotria sp.), kacihe leave (Prunus accuminta Hook), umbrella tree leave (Maesopsis eminii Engl), mutamba leave (Guazuma ulmifolia Lamk), cepcepan leave (Villebrunea subescens Blume), pirdot/cepcepan lembu leave (Saurauia vulcani Korth), raru bark (Cotylelobium melanoxylo), breadfruit leave (Artocarpus altilis), salam leave (Syzygium polyanthum Wight), mahogany seed (Swietenia mahagoni (L.) Jacq), cinnamon bark (Cinnamomum burmani), and yellow bamboo rod (Bambusa vulgaris Schrad). Five of those plants: loning, umbrella tree, mutamba, raru and salam have the highest cultural significance level. These five plants are highly needed in large quatities by the Karo people, so their availability in the forest should be securely conserved and protected. The plants used contained alkaloids, flavonoids, phenolics and terpenoids which can help to lower blood sugar level.

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. Pengambilan data dilakukan dengan cara survei menggunakan kuesioner pada rumah tangga yang menjadi sampel. Hasil pengolahan data memperlihatkan bahwa kebutuhan air bersih di tiga perumahan berkisar pada rentang nilai antara ±158,84 Liter/Orang/Hari sampai 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

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).

Abstract

ABSTRACTCommunity forest (HKm) as one scheme of social forestry has been established in Central Lombok Regency since 1999 and was legalized in 2010. The HKm covered an area of 1,809.5 ha and has formed an agroforestry pattern since it was first established 13 years ago. However, the plant distribution and economic value of production area remain unknown. Therefore this research is designed to record plant composition and calculate the economics value of HKm in the research area. Survey method using analysis of vegetation was carried out to measure the plant composition. Sampling intensity was 0.01% or 1.81 ha with a total number of sample plots were 45. Survey was also used to calculate the economic value, with sampling intensity of 1% or in total 32 households. The results showed that the plant composition consists of mature trees (2.02%), young trees (4.12%), sapling (26.44%) and seedling (67.41%). The plant density was 11,462 ind/ha and dominated by Coffea sp., Musa sp., Durio zibethinus, Theobroma cacaoa and Arthocarpus heterophyllus with proportion of 24.08%; 13.70%; 9.25%; 7.48% and 5.30%, respectively. Total economic value in the average was Rp 6,366,484/household/year or Rp 530,540/household/month. There was a downward trend in HKm production due to increased vegetation coverage. Exchange rate of HKm commodities can be improved by applying supporting strategic programs in HKm developments.   ABSTRAKPembangunan Hutan Kemasyarakatan (HKm) di Kabupaten Lombok Tengah telah dimulai sejak tahun 1999 dalam bentuk ijin sementara pengelolaan HKm dan kemudian diterbitkan Ijin Usaha Pengelolaan Hutan Kemasyarakatan (IUP-HKm) pada tahun 2010 dengan luas areal 1.809,5 ha. Kawasan HKm dalam waktu tiga belas tahun (2000-2013) telah  membentuk formasi hutan pola agroforestri. Namun demikian, distribusi tanaman dan nilai produksi kawasan belum diketahui. Untuk itu dilaksanakan penelitian guna mengetahui komposisi tanaman dan nilai produksinya. Penelitian dilaksanakan menggunakan metode survei dengan melakukan analisa vegetasi untuk mengetahui distribusi tanaman dengan intensitas sampling sebesar 0,01% atau 1,81 ha dengan jumlah plot sebanyak 45 unit. Untuk mengetahui nilai ekonomi dari produksi tanaman dalam HKm, dilaksanakan wawancara terhadap petani penggarap HKm dengan intensitas sampling 1% atau sebanyak 32 petani. Hasil penelitian menunjukkan bahwa komposisi tanaman yang ada dalam areal HKm terdiri dari strata pohon sebesar 2,02%, tiang 4,12%, pancang 26,44% dan semai 67,4%. Kerapatan tanaman 11.462 btg/ ha yang didominasi oleh tanaman kopi (Coffea sp.), pisang (Musa sp.), durian (Durio zibethinus), coklat (Theobroma cacao) dan nangka (Arthocarpus heterophyllus) dengan proporsi berturut-turut 24,08%; 13,70%; 9,25%; 7,48% dan 5,30%. Nilai ekonomi yang diperoleh rumah tangga petani rata-rata sebesar Rp 6.366.484/tahun atau Rp 530.540/bulan. Terdapat kecenderungan penurunan nilai produksi HKm akibat semakin meningkatnya penutupan lahan. Untuk meningkatkan nilai tukar komoditas HKm, diperlukan program strategis yang dapat mendorong pembangunan HKm.

Abstract

The research is purposed to assess the financial feasibility of agroforestry system which consisted of “suren” (Toona sureni Merr.) and arabica coffee (Coffea arabica L.) in Aek Nauli and Sipolha Horizon Village, North Sumatra. The data was collected from farmers in both villages from March up to July 2015, then analysed using financial feasibility parameters such as NPV, BCR, and IRR. The results shows that this farming system is financially feasible at the interest rates of 5,65% for the average farming scale amounted to 0,22 hectares per 15 years cycle. This system emerges NPV value IDR. 166.792.215,73/cycle/farm, BCR value is 22,80, and IRR is 38,90%. Based on these findings it is needed to compensate additional input for the farmers who can’t harvest their suren which is located on the buffer zone because the stands are utilized to conserve the vulnerable site. Keywords: financial feasibility, agroforestry, intercropping, arabica coffee, suren (Toona sureni)

Abstract

Lack of attention to the non-staple food sectors and changes in consumption pattern have resulted in decreasing of farmers' preference in cultivating sago, which ultimately results in the conversion of sago land including in Asahan District. This study aims to measure the level of community preference in managing sago and to reveal the factors that influence the level of people’s preference. Data were collected from 98 respondents by using questionnaire method and analyzed by descriptive statistical analysis, frequency tab, and spearman rank correlation. Research was conducted from May to December 2015 in Silo Bonto Village, Sei Paham Village, and Sungai II Hulu Village. The results showed that level of people’s preference in managing sago was moderate with an average value of 27.92. Ecological benefit factor from sago cultivation dominated the reason of community's interest in managing sago (40.48%), followed by economic factor (33.97%,) and sago consumption (25.54%). Socio-economic characteristics of respondents such as age, number of family dependents, farmland area, sago stands, and length of sago business have a significant correlation to the level of preference. Older farmers, fewer family dependents, sufficient farmland, and longer experience in sago palm utilization seem to prefer to manage sago cultivation.

Abstract

This paper presents the correlation between socio-economic characteristics of the community around Ciliwung river basin with effort to reduce the concentration of household wastewater after treatment by using demonstration site station (DSS). Effects of socio-economic characteristics of the community which are categorized as internal and external factors that encompassed their decision in DSS application was tested by using logistic regression analysis. The results showed that the decision DSS adoption was affected by intrinsic factors such as the mothers’ role on every family and knowledge of the benefits of 3R (reduce, reuse, recycle) in waste management, as well as external factors such as key person leadership regarding household liquid waste management and availability of domestic waste processing installation. Moreover, water quality test after DSS treatment showed that declining concentration of tested parameters were among others: total phosphate (T-P), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solid (TSS), potential of hydrogen (pH), and oil and fat. Oil and fat parameter can be controlled through waste sorting, in DSS, while methylene blue active substances (MBAS) had no effect.

Abstract

Penelitian mengenai kontaminasi merkuri (Hg) pada media lingkungan akibat aktivitas PESK masih diperlukan, untuk digunakan sebagai data dasar dalam perumusan rencana penghapusan dan pengurangan merkuri.  Tulisan ini menyajikan hasil penelitian mengenai distribusi konsentrasi Hg akibat PESK pada perairan sungai, ikan air tawar dan sedimen di Kalimantan Tengah.  Data yang digunakan adalah data hasil pengukuran P3KLL pada tahun 1999-2008 dan hasil pengukuran terbaru yang dilakukan oleh Direktorat PB3-KLHK pada tahun 2018. Analisis Hg dilakukan menggunakan Mercury Analyzer Hg-5000 metode cold vapour, preparasi contoh uji  sesuai dengan Standar Internasional Jepang (JIS) dan Standar Nasional Indonesia (SNI). Hasil penelitian menunjukkan bahwa pada sebagian besar lokasi sampling menunjukkan konsentrasi merkuri dalam air sungai masih berada di bawah standar Peraturan Pemerintah Nomor 82 Tahun 2001 untuk air kelas I (0,001 mg/L), namun di 2 lokasi lebih tinggi daripada standar tersebut.  Merkuri yang terkandung dalam sampel ikan air tawar dari sungai di sekitar PESK, ditemukan pada kisaran 0,08 - 0,224 mg/kg. Nilai ini masih berada  di bawah nilai persyaratan kontaminasi logam pada ikan sesuai SNI:7387 2009 (0,5 mg/kg). Kandungan merkuri dalam kisaran sedimen antara 0,0291 - 0,45 mg/kg, di mana beberapa lokasi sudah berada di atas nilai baku yang di atur dalam Quality Guidelines for Freshwater of Canadian Environmental Quality (CEQ), yaitu 0,17 mg/kg.
