SELECTION OF CROSSING FACILITIES BASED ON CRITICAL GAP (CASE STUDY DHARMAWANGSA STREET, SURABAYA) Edwin Hidayat
Widyariset Vol 15, No 3 (2012): Widyariset
Publisher : Pusbindiklat - LIPI

Pedestrians have a high risk to be hit by motor vehicle when they crossed the street, thus the choose ofappropriate cross facilities are very important. An alternative for choosing cross facilities are by using the CriticalGap method. This method is used to measure the possibility of crossing the street safely. This study was startedby gathering primary data for 4 hours at the traffic peak hours. From the calculation, the case of DharmawangsaStreet, Surabaya, showed that the critical gap is about 3,55 seconds. The observation from 07.00-11.00 a.m.showed that the possibilities of crossing the road respectively are: 45, 55, 56, and 60. Compared to the numberpedestrians crossing the road, the research showed about 71, 24, 33, and 49 peoples. In this case, the possibility ofcrossing the street at 07.00-08.00 a.m. cannot be fulfilled. Meanwhile, the possibility to cross the street with safelyat 08.00-11.00 a.m. can be fulfilled. Therefore, the use of midblock crosses is still relevant.

Publisher : Pusbindiklat - LIPI

Bamboo has contributed to economic potency and the increase of ecology, so bamboo is widely used by local and non-local community. Objectives of this research is to verify role of bamboo betung (Dendrocalamus Asper)at land quality using method Ring rudihilmanto, but in this research it is focussed only at land element influenced by bamboo betung especially at acidity (pH) and porosity. Method of Ring rudihilmanto constitute method of tree interaction and adaptation. This method depicts environmental elements which can be influenced by population a tree species of phase its growth and development at ecosystem, that is: land, temperature, water, and the other organism. Result obtained by that role of bamboo of betung at ecosystem use method of Ring rudihilmanto had ability 14,29% improve alkalis soil and 12,55% to improve soil porosity. Role of bamboo betung (Dendrocalamus Asper) at land quality repair was different significant at 0,01 level.

FARMER PREFERENCES ON QUALITY AND YIELD CHARACTERISTIC OF NEW PADDY VARIETIES IN DONGGALA DISTRICT Heni S.P. Rahayu
Widyariset Vol 15, No 2 (2012): Widyariset
Publisher : Pusbindiklat - LIPI

New improved variety is a component of technology that hold an important role in increasing rice production. Farmers preferences of improved varieties have to be known because it affects on the level of farmer adoption of new paddy varieties. The aims of this research are to understand the characteristics of paddy that are important to farmers and to know the most prefered new varieties in Donggala. The research is a participatory research which supported by site observation. The data were analyzed by perceived quality method. The results show that the characteristics that are important to farmers preference in Donggala are production, pest and disease rate, the number of tillers, rice texture, the ease of harvest, the age of harvest, plant height and panicle length. However the paddy variety which is most favored by the farmers in Donggala is Inpari 4.

Widyariset Vol 18, No 1 (2015): Widyariset
Publisher : Pusbindiklat - LIPI

Most of the farmer groups managing cattle in West Sumatra have not achieved the business goals with little regard for the potential well and local resources that surround them and the lack of attention to environmental impact. The purpose of this study was to describe the performance of the enclosure management, feeding management, livestock waste management with respect to the concept of Green Marketing, and describes prospects for the cattle business in West Sumatra sustainable future. The research was conducted in 2012 in farmer groups Sejahtera Rambatan, Tanah Datar and groups Sejahtera Dua, in West Pasaman. The method used is the qualitative and quantitative approaches. The results of this study were (1) cage is best for beef cattle business is to facilitate the enclosure of communal feeding and cleaning cages. Need a good cage equipped breeding tank waste. (2) Management of by-product feed by utilizing skin cocoa plantations, palm leaf midrib and Solid largely able tosubstitute consentrate feed and forage with greater economic value. (3) By processing waste in the form of cattle faeces, cow urine and feed residue into organic fertilizer for farmers and provide benefits to cover the cost of feedproduction.

Banda arc has a high seismicity, therefore, it is necessary to reduce the earthquake risk. Earthquake parameters variation from Gutenberg - Richter relation, log n(M)=a – bM, has introduced the model of earthquakes prediction related to earthquake risk. Earthquake data from NEIC catalogue for a period of 1973 - 2009 has been used to analyze earthquake parameters variation (a-value, b-value) in the area of Banda arc within coordinates 1°-13° S and 120°-135° E. This research used ZMAP ver. 6.0. to analyze the earthquake data. The result of spatial analyze shows the areas of potential destructive earthquakes are surrounding of Flores, Alor and western part of Seram. The probability of earthquakes occurrence with the magnitude 6.5 RS in these areas is 7 – 15 years, whereas the magnitude 7 RS is about 20–60 years.

Beberapa penelitian telah dilakukan, tetapi belum ada yang membahas secara khusus retensi dalam bahasa Melayu Banjar Hulu. Penelitian ini dilakukan untuk mengidentifikasi retensi dan inovasi fonemis dalam bahasa Melayu Banjar Hulu, membandingkan dengan penelitian terdahulu, dan menghubungkannya dengan bahasa Melayu kuno. Data berupa 200 kosakata dasar yang dikumpulkan Suryadikara dan Durasjid diban-dingkan dengan daftar proto-Austronesia yang dihimpun Blust. Dengan metode komparatif diketahui ada lima protofonem, *t, *m, *a, *i, dan *u, yang mengalami retensi pada semua posisi. Karena mempertahankan secara konsisten ketiga protofonem vokal tersebut, bahasa Melayu Banjar Hulu dapat disebut bahasa yang masih asli. Sementara itu, protofonem yang mengalami retensi jika berada pada posisi awal adalah *b, *d, *k, *l, *p, dan *s. *k, *n, *p, dan *r dipertahankan jika berada pada posisi akhir, sedangkan *l, *n, *b, *s, *r, dan *Å dipertahankan jika berada pada posisi antarvokal. Inovasi primer yang ditemukan hanya substitusi, sedangkan inovasi sekunder yang didapat berupa split, apokope, sinkope, protesis, dan metatesis.*q merupakan satu-satunya protofonem yang mengalami substitusi menjadi /h/ pada semua posisi.

Addition to its economic contribution, rubber plantation plays an important role in sequestration of carbon. Carbon sequestration of rubber plantation could be increased through the application of intercropping system with high biomass timber trees. This study aimed: 1) to asses the potential increase of land carbon stock in rubber plantation intercropped with teak (Tectona grandis) and trembesi (Samanea saman); and 2) to examine theroleofforestryplantsintercroppingonrubbertreesasanalternativetoreduceCO2 emissions.Theresearch was conducted at the Balai Penelitian Sembawa’s plantation, South Sumatera, with three intercropping patterns, namelyPT1:teak+rubberplants,PT2:trembesi+rubberplants,andPT3:rubbertreemonocultures.Carbon stocks measurement is divided into three components: living part (tree biomass), dead part (necromass) and soil (soil organic matter). The results showed that the highest value per hectare of tree biomass, litter and soil carbon wasatPT2experimentwhilethelowestwasatPT3.TotalCO2 fixationperyearatPT1,PT2,andPT3were 18.54tons/ha,35.69tons/haand32.34ton/ha,respectively.Theincreaseincarbon sequestrationlevelbecause oftheexistenceoftrembesiwas9.3%oraround0.92tonnesC/ha/year,higherthanthatinmonoculturerubber plantation. 2 theroleofforestryplantsintercroppingonrubbertreesasanalternativetoreduceCO
