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.
Black soldier fly (BSF) larvae (Hermetia illucens) can be used as insect based municipal organic waste recycling technology. The purpose of this research was to examine the utilization of BSF larvae as bio-processors of organic waste in order to produce compost and nutritious larvae biomass. Larvae feeds as treatments of experiment consist of restaurant organic waste mixed with fish silage 6% as treatment A, restaurant organic waste with dairy blood waste 6% as treatment B, and restaurant organic waste as treatment C. The result of this research showed that the highest larvae growth according to its length, width and body weigth was resulted by treatment B, followed by treatments A and C. Total metamorphic development time from egg to imago was 35 days; comprised of as larvae, prepupa, pupa, and imago for 12-13, 6, 6, and 15 days, respectively. Proximate analysis showed that BSF larvae had protein content 33.31 to 33.88%, and fat content 30.07 to 34.39%. Final solid residues of the three treatments was ranged from 90.3-90.6% after 10-11 days of bio-processing.
Penelitian ini bertujuan untuk mengamati dan mengkaji hubungan suhu, kelembaban dan manajemen ternak terhadap efisiensi reproduksi sapi perah di Kabupaten Bogor. Suhu dan kelembaban udara diamati pagi, siang dan sore hari. Data suhu dan kelembaban udara dikonversi ke nilai indeks suhu kelembaban udara (THI). Pengamatan parameter efisiensi reproduksi dilakukan dengan menghitung nilai Days Open (DO), Conception Rate (CR), Service per Conception (S/C) dan First Service. Hasil penelitian menunjukkan bahwa nilai THI Acep Farm Kunak (77,21±0,71) lebih tinggi (P<0,05) dari Cifa Farm (71,27±0,50) dan Erif Farm (71,22±0,41). Days Open Acep Farm Kunak (110,76±37,34 hari) lebih panjang (P<0,05) dibandingkan dengan Cifa Farm (88.39±23,80 hari) dan Erif Farm (88,20±22,39 hari). Nilai CR Acep Farm (75,76±0,11%) dan Cifa Farm (66,13±0,10%) tidak berbeda (p>0,05) dibandingkan dengan Erif Farm (42,00±0,08%). Nilai S/C di tiga peternakan tidak menunjukkan perbedaan (p>0,05) masing-masing nilai S/C Cifa Farm (1,42±0,64), Erif Farm (1,52±0,64) dan Acep Farm Kunak (1,64±0,82). First Service Cifa Farm (76,11±13,84) dan Erif Farm (75,17±13,17) berbeda (P<0,05) dengan Acep Farm Kunak (96,42±35,49). Dapat disimpulkan bahwa suhu, kelembaban udara dan manajemen pemeliharaan dapat memengaruhi DO sapi perah di ke tiga peternakan sapi perah di ke tiga lokasi penelitian. Lebih lanjut, diindikasikan THI memengaruhi zona nyaman peternakan sapi perah, namun tidak ditemukan korelasi positif antara nilai THI dengan tingkat efisiensi reproduksi.
Dairy farming system in Bogor Regency deals with threatening problems. This research aims to assess and to analyze sustainability of dairy farming system of smallholding farms in Bogor Regency. The respondents consisted of dairy farm area (Kunak) and smallholding farms in Cisarua District. Approach used in this study was a rapid appraisal for dairy farm system (Rap-Sibusape) using a multidimensional scaling (MDS) method. Results showed that smallholders in Cisarua and Kunak had index values of system dairy farms sustainability of 51.25 and 54.12, respectively. It indicated that the two areas are quite sustainable. Analysis five sustainable dimensions (ecology, economy, socio-culture, infrastructure technology, and institutional law) showed that ecology was sustainable on Kunak, and economy and socio-culture were not sustainable on both Kunak and dairy farm in Cisarua. Leverage analysis results showed that there were 15 out of 45 attributes influencing the sustainability index system. There were six key factors strongly influenced the system with low dependence among factors, i.e. (i) milk prices, (ii) feed carrying capacity, (iii) development cooperation, (iv) input subsidies, (v) micro finance, and (vi) socialization work. Improving dairy cattle farming in Bogor Regency requires sustainability index value enhancement of 15 sensitive attributes focused on 6 key factors affecting the dairy cattle farming system. Key words: sustainability, dairy cattle, dairy farming, Bogor Regency ABSTRAKPeternakan sapi perah di Kabupaten Bogor menghadapi permasalahan yang mengancam keberlanjutan sistem, seperti (i) keterbatasan pakan hijauan, (ii) penurunan jumlah peternak, (iii) rendahnya mutu susu, (iv) penyakit ternak, dan (v) terbatasnya sarana-prasarana agribisnis. Oleh karena itu, perlu dikaji status keberlanjutan sistem peternakan sapi perah di Kabupaten Bogor untuk memperoleh manfaat optimal dari kinerja sistem. Penelitian ini bertujuan untuk menilai dan menganalisis keberlanjutan sistem peternakan sapi perah rakyat di Kabupaten Bogor yang diwakili oleh Kawasan Usaha Ternak (Kunak) dan peternakan rakyat Cisarua dengan metode rapid appraisal sistem peternakan sapi perah (Rap-Sibusape) menggunakan pendekatan multidimensional scaling (MDS). Penilaian Rap-Sibusape menunjukkan Kunak dan peternakan rakyat Cisarua memiliki rataan nilai indeks keberlanjutan sebesar 51,25 dan 54,12 sehingga berkategori cukup berkelanjutan. Analisis lima dimensi keberlanjutan (ekologi, ekonomi, sosial-budaya, teknologi-infrastruktur, dan hukumkelembagaan) menunjukkan dimensi ekologi tidak berkelanjutan pada Kunak, dimensi ekonomi dan sosialbudaya tidak berkelanjutan pada Kunak dan peternakan rakyat Cisarua. Analisis leverage menunjukkan terdapat 15 atribut dari 45 atribut berpengaruh terhadap indeks keberlanjutan sistem peternakan sapi perah. Analisis prospektif menunjukkan terdapat 6 faktor kunci berpengaruh kuat terhadap sistem dengan tingkat ketergantungan antarfaktor yang rendah namun berpengaruh besar terhadap sistem. Enam faktor kunc...
