Abstract

Residential solid waste is being a critical problem in many cities in clauding Jakarta.  Cummnity-based management is the most important strategy even when sophiticated treatment such as bio-energy or waste industrial park word be implemented soon, as every waste processing neds separated wastes.  Increasing the participation through community-based manajement is more effective than cange people?sperception and behavior on domestic wastes.  In some cates, to change community behavior in waste separition and recycling need more than ten years i.e. at Kampung Banjarsari, but with appropriate support system on sosial planning only took two years i.e. Kampung Rajawati.  The implementation constrain of this progammeis on replication or expandability of the progamme to implemented in another place.  There are also lack of government?s significantefforts to push and to supprots than action.  It?s true that some cummunities develop the some model, but without acceleration and exvandable progamme, the significance of that effort is very poor.  This study tried to ellaborate the model of system based ofnspatial analyses to determine resedential typology and found five resedential types i.e. high, middle-high, middle, middle-lower and lower level of resendential.  Quantitative analyses to determine typology of community participation found four types of cummnity participation i.e. moral-normative, moral-remunerayive, calculative-remuneraive and calculative-coercive.  Qualitative analyses had been ellaborated to determine authority or government policies typology.  Breaking down from these clssification, there strategies could develop, namely community participation strategy, infastructure development strategy and institutional manajement strategy.  Implementation of these models could accomodate the heterogeneity of communities and give positive impact on social acceptability.   Key words: social planning, community management, residential solid wastes

Abstract

Transmigration program has been done for many years. However, many transmigration sites are identified as underdeveloped, especially in upland farm transmigration site laboured with food crops. The main constraint for such development relates with the limit of upland resource in supporting plant growth. The upland resources is generally marginal in physical properties (undulating, wavy and hilly topography); the poor quality in land clearing which cause removal upper layer and loss of organic matter; relatively high rainfall intensity which causes the high erosivity. Such degradation has caused accumulation of problem for farmer. This research in erosion is done in order to know the strategy needed to be done. This research is done in Rantau Pandan SP 1 as case study. Several methods have been applied to determine 1) the amount of erosions 2) the permissible erosion, 3) the spatial pattern of erosion,and 4) the soil conservation action.   Key words: upland farming system, erosion, conservation

Abstract

           The objective of this study was evaluate horticultural performance of several maize genotypes and their potential to be developed as baby corn. The experiment was conducted at Sindangbarang Experimental Station of Bogor Agricultural University Bogor, from April until June 1995.            The design used was randomized complete block design (RED) with three replications. Fifteen genotypes consisted of local maize (8 numbers), improved variety (3 numbers) and introduction (3 numbers) were evaluated with CP1-1 hybrid which has been usual in producing baby corn was used as control variety.           The result showed that the introduced genotypes CM-90 and SPLC6 gave highest number of baby corn with yield of 2.60 ear per plant (equivalent to 3.04; ton/ha) and 2.20 ear per plant (equivalent to 3.04 ton/ha), respectively, while CP1-1 hybrid only produced 1.80 ear per plant (equivalent to 1.72 ton/ha). Therefore, CM-90 and SPLC6 were found to have higher yield of marketable baby corn than the control variety. Considering days to harvest of baby corn, CM-90 (56.05 dap)was found earlier than SPLC6 (61.60 dap).

Abstract

A field experiment to obtain new improved soybean varieties with higher yield and seed size was conducted by crossing Slamet Variety (high yield, small seed size) with Nakhonsawan (large seed size) in order to produce F6 selected generation. The process of selection and evaluation was conducted during a 3.5 month period, from August to December 2003 in KP IPB Sindang Barang Bogor. The pedigree selection method was used in the experiments. Data was analyzed based on information of set of total data, relatives and individually. The results showed that low performance for all traits compared to the Slamet variety except seed size and seed production traits, and higher than Nakhonsawan variety except seed size. However, genetic variances and heritabilities were high for all traits except number of branch. On the other hand, distribution of genetic variances and heritabilities on all levels of relatives were small except for the within-family F6 generations. This indicated that there was an effect of over-dominance gene action. Conclusion of analysis showed existence of two families with high seed production and seed size if compared to Slamet variety.   Key words: Soybean, selection, performance, genetic variability, and heritabilities.

Abstract

Population growth and changes in consumption pattern have increased the municipal waste volume in DKI Jakarta. Waste management issue has been more formidable after the government has failed to overcome the situation with sufficient waste management facilities. Hence, society’s active participation is needed to create a more comprehensive system of municipal waste management, based on “reduce, reuse, recycle” principle. The objective of this study is to (1) identify the community perception and participation in the household waste management, (2) analyze the correlation between the internal and external factors of individual with the perception on the household waste management, and (3) analyze the correlation between community perception and participation in household waste management. The observed variables are divided into two factors, namely internal factors and external factors. The data were collected using survey method by distributing questionnaire, while Chi Square Test and Spearman Rank Correlation Test were used for data processing. The results showed that respondents have positive perception and high participation in the household waste management. There is a significant correlation between the internal and external factors of individual with community perception on the household waste management. Community perception on household waste management is also significantly correlated to community participation in household waste management.

Abstract

Genetic diversity is the most important aspect in tomato breeding activities. Better assessment on the diversity of the collected accessions will come up with better result of the cultivar development. This study aimed at analyzing the genetic diversity of 27 tomato accessions by morphological and molecular markers. Twenty seven accessions collected from various regions of Indonesia were planted in the field and evaluated for their morphological traits, and RAPD analyzed for their molecular markers. The UPGMA clustering analyzes, elaborating the combination of morphological and molecular data, indicated that the tomato accessions could be grouped into 5 major groups with 70 % genetic similarity levels. Current study indicated that although many accessions came from different locations, they congregated into the same group. Cherry, Kudamati 1 and Lombok 3 were the farthest genetic distant accessions to the others. Those three genotypes will be the most valuable accessions, when they were crossed with other accessions, for designing a prospective breeding program in the future.

Abstract

The development implemented throughoutall this time still reveals an unbalanced development between the urban andrural area. This has occured due to the development policy that is lessfavorable toward the development of rural areas causing various  problems of imbalances (inequalities) ofwelfares among the regions. In addition, the failures of development in therural areas have caused backwash effect, and the domination of capital marketand welfares have been mostly possesed by the urban dwellers. The conditionof  rural communities have become moredeteriorated, poorer, and the level of unemployment becoming higher. Thedevelopment of agropolitan (agro-based area development) is expected to providepositive impact in the effort to empowering the rural community, reducingpoverty, and supporting rural economic activities that are environmentallyoriented. This study aims to develop a sustainable rural policy through theagropolitan development model, based on regional analysis, insitutional analysis(ISM), and dynamic system. The agropolitan development is relatively able toimprove the income per capita of the rural population. Dynamic system analysisshowed that the agropolitan model follows the basic pattern of Archetype Limitto Success, with production growth as a leverage factor of the dynamic model.Thus, the policy orientation to improve people's welfare is a policy that ableto improve the quantity and quality of products in a sustainable manner. Theresult of analysis of institutional aspect showed key factors that supportsuccessful agropolitan development which are skilled human resources, businesspartnership and marketing, and the performance of institutions that provideinput. The major constraints faced are small size land ownership and productiveagriculture land conversion, extension services agencies that are not yeteffective, low quality of human resources, business behavior change not easy,and low support of capital institution.

Abstract

Pengembangan hunian vertikal di Kota Depok merupakan salah satu alternatif strategi memenuhi kebutuhan perumahan bagi masyarakat terutama Masyarakat Berpenghasilan Rendah (MBR), mengurangi backlog, dan mengoptimalkan pemenuhan Ruang Terbuka Hijau (RTH). Penelitian ini bertujuan untuk membangun model pengembangan hunian vertikal menuju pembangunan perumahan berkelanjutan dan implikasinya terhadap kebijakan pembangunan perumahan bagi MBR. Metode analisis data yang digunakan meliputi analisis deskriptif, analisis statistika, analisis finansial, analisis input-output (I-O), dan analisis sistem dinamik. Hasil penelitian menunjukkan bahwa masyarakat Kota Depok memiliki potensi minat yang besar terhadap hunian vertikal namun tingkat keterjangkauan terutama MBR masih sangat rendah. Untuk meningkatkan keterjangkauan masyarakat dalam memiliki hunian, maka peran pemerintah sangat diperlukan terutama dalam pemberian bantuan dan insentif kepemilikan hunian. Pembangunan perumahan juga memberikan dampak ganda (multiplier effect) terhadap pembangunan di Kota Depok dan daerah sekitarnya. Dampak tersebut antara lain tingginya pembangunan perumahan, meningkatnya pendapatan masyarakat, dan  tingginya tingkat penyerapan tenaga kerja akibat pembangunan perumahan.  Peningkatan kebutuhan jumlah hunian, serta backlog perumahan di Kota Depok menunjukkan kecenderungan pertumbuhan mengikuti kurva eksponensial pada tahun simulasi 2001 sampai tahun 2025. Untuk memenuhi kebutuhan rumah bagi masyarakat di Kota Depok khususnya MBR dengan mempertimbangkan kemampuan masyarakat dan mempertahankan ketersediaan lahan RTH pada tingkat tertentu, skenario yang dapat dilakukan adalah memanfaatkan RTH sampai pada luasan 5000 ha, dengan mendorong pertumbuhan hunian vertikal melalui subsidi bunga sebesar 8% dan subsidi uang muka sebesar Rp 10.000.000 – Rp 13.000.000.
