Saat ini permasalahan lingkungan menjadi pertimbangan yang sangat penting dalam produksi biodiesel. Meskipun sumber energi ini (biodiesel) dianggap sebagai karbon netral, namun dalam rangkaian proses produksinya masih menghasilkan berbagai gas berbahaya ke lingkungan. Negara-negara Eropa dan Amerika mengklaim bahwa produksi biodiesel dari minyak kelapa sawit memberikan kontribusi emisi karbon ke atmosfer sepanjang jalur produksinya. Selain itu, US EPA-NODA dan EU RED menyatakan bahwa biodiesel dari minyak kelapa sawit hanya dapat mengurangi emisi GWP 17%  dan 19% dibandingkan dengan bahan bakar berbasis fosil. Mengingat bahwa persyaratan minimum US adalah 20% dan EU adalah 35%, maka minyak kelapa sawit dari Indonesia mengalami kesulitan untuk memasuki pasar global. Pendekatan ilmiah harus dilakukan oleh Indonesia untuk mengatasi masalah ini. Tinjauan dari berbagai literatur menyebutkan bahwa keberlanjutan produksi biodiesel dari kelapa sawit lebih baik dibandingkan jarak pagar, bahkan apabila dibandingkan dengan bahan baku yang lain seperti lobak. Tinjauan dari berbagai literatur menyebutkan bahwa nilai karbon yang dapat diserap oleh hutan primer lebih tinggi dari hutan sekunder dan dari perkebunan kelapa sawit. Kondisi inilah yang menjadi alasan mengapa dunia menyebutkan bahwa Indonesia sebagai penyebab pemanasan global, meskipun penelitian lebih lanjut masih dibutuhkan berdasarkan data terakhir di Indonesia. Dari kondisi ril di Indonesia diperoleh nilai GRK sebelum produksi stabil yaitu 2.575,47 kg-CO2eq./ton-minyak biodiesel (BDF) untuk minyak kelapa sawit dan 3.057,74 kg-CO2eq./ton-BDF untuk minyak jarak pagar. Ketika produksi sudah stabil diperoleh nilai GRK sebesar 1.511,96 kg-CO2eq./ton-BDF untuk minyak kelapa sawit and 380,52 kg-CO2eq./ton-BDF untuk minyak jarak pagar. Jika kita bandingkan dengan minyak solar, maka nilai emisi CO2eq. dapat diturunkan  49,27 % untuk biodiesel dari minyak kelapa sawit dan 88,45 % untuk biodiesel dari minyak jarak pagar. Review of Life Cycle Assesment of Biodiesel in Indonesia Abstract. Currently, environmental consideration becomes the most important issue in biodiesel production. Eventhough source of energy is considered as carbon neutral, the production path may release various environmentally hazardous gasses. European and American countries claim that production of biodiesel from palm oil contributes carbon emission to the atmosphere along its production path. Furthermore, US EPA-NODA and EU RED stated that palm oil based biodiesel can only reduce emission of GWP by 17 % and 19 % compared to fossil-fuel based. Considering on the minimum requirement is 20 % for US and 35 % for EU, CPO from Indonesia experiences difficulties to enter the global market. Scientific approach should be undertaken by Indonesia to address this issue. Summary of the literature mentions that the sustainability of biodiesel from palm oil is better than Jatropha curcas, compared to other sources of raw materials, such as rapeseed. Summary of the literature mentions that the value of carbon that can be absorbed by primary forest is higher than secondary forest and palm oil plantation. This is the reason why world claims Indonesia on global warming issues although further research is still needed based on the latest data. From the real condition in Indonesia, in which GHG value before stable productivity is 2 575.47 kg-CO2eq./ton-Biodiesel fuel(BDF) for oil palm and 3 057.74 kg-CO2eq./ton-BDF for Jatropha curcas. When the productivity has reached stability, the GHG value is  1 511.96 kg-CO2eq./ton-BDF for oil palm and 380.52 kg-CO2eq./ton-BDF for Jatropha curcas. If we compared to diesel fuel, CO2eq. emission is reduced up to 49.27 % and 88.45 % for BDF-CPO and BDF-CJCO, respectively.

Hasil pengujian menunjukkan bahwa massa input buah jeruk dan kecepatan linier bidang sortasi memberikan pengaruh yang signifikan terhadap kinerja mesin sortasi ini, sedangkan kemiringan bidang sortasi berpengaruh tetapi tidak signifikan. Hasil uji kinerja terbaik diperoleh pada perlakuan massa input 2 kg, kemiringan bidang sortasi 10o dan kecepatan linier bidang sortasi 1,09 m/s dengan nilai kapasitas penyortiran 1,84 kg/menit atau 110,4 kg/jam dan efisiensi penyortiran 68 %. Performance Testing of Citrus Sorting Machine with Rotation System to Sorting Pontianak Siam Citrus (Citrus nobilis var. microcarpa)Abstract. One of postharvest  activities that required much time are sorting in Sambas district. The sorting process is still done manually, where the level of uniformity of size and currently their maturity level are including the low of the quality standard fickle and sorting capacity. To overcome these problems, a study was developed to design citrus sorting machine with rotation system. This study aims to test the performance of the citrus sorting machine with rotation system and to determine the effect of linear velocity of sorting, incline angle and  the input mass of citrus. Performance testing was conducted  with 4 linear velocity sorting (0,54 m/s, 0,70 m/s, 0,82 m/s and 1,09 m/s), 3 incline angle (10o, 20o and 30o) and 3 input mass of citrus (2 kg, 3 kg and 4 kg). The test results showed that the input mass of citrus and linear velocity sorting have a significant influence on the performance of the sorting machine, while the incline angle has an effect but did not significantly. The best performance test results was obtained on 2 kg of mass, 10o of incline angle and 1,09 m/s linear velocity of sorting which resulted 1,84 kg/min or 110,4 kg/h of sorting capacity and 68 % of sorting efficiency.

This study aimed to determine the level of erosion that occurred on the slopes of plantation of coffee community in sub-district of Permata, district of Bener Meriah, Province of Aceh, conducted from January to August 2011. Coffee plantations of community were located in sub-district of Permata as samples, particularly in the village of Jungke which had 8 percent slope and the village of Seni Antara which had 30 percent slope. This study was conducted by field observation and laboratory analysis to predict the values of erosion using the method of USLE (universal soil loss equation). Further Erosion Hazard Level (TBE) was determined by considering the effective depth of soil. The results showed that the value of the actual erosion that occurred in the coffee plantation of community in the village of Seni Antara which had 30 percent slope at 87,711.47 tones ha-1 year-1 greater than the actual value of erosion in the village Jungke which only 8 percent slopes at 21.79 tones ha-1 year-1. Erosion Hazard Rate on slopes of 30 percent (village of Seni Antara) classified as very heavy, while TBE at 8 percent slope (Village of Jungke) as light. The main factors that affected the value of erosion were the value of LS (long and large slope) and the value of K (erodibility). To prevent erosion on coffee plantations advised people to be able to add shade trees, use of litter and planting cover crops.  Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RTP/article/view/231 10.17969/rtp.v5i2.231 Language A language of the resource eng Publisher An entity responsible for making the resource available Program Studi Teknik Pertanian, Fakultas Pertanian, Universitas Syiah Kuala Relation A related resource http://jurnal.unsyiah.ac.id/RTP/article/view/231/217 Source A related resource from which the described resource is derived Rona Teknik Pertanian; Vol 5, No 2 (2012): Volume 5, No. 2, Oktober 2012; 341-346 2085-2614 2085-2614 Subject The topic of the resource erosion; Level of Erosion Hazard; USLE Title A name given to the resource Prediksi Erosi Kebun Kopi Rakyat di Kecamatan Permata, Kabupaten Bener Meriah, Provinsi Aceh Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Diversifikasi produk olahan rumput laut adalah salah satu upaya untuk meningkatkan daya guna dan nilai ekonomis rumput laut, yaitu dengan cara mengolah rumput laut jenis Eucheuma cottonii menjadi mie basah. Mie basah merupakan hasil pengolahan berbahan dasar tepung yang dicampur dengan bahan tambahan lainnya. Tepung yang sering digunakan dalam pembuatan mie adalah tepung terigu dan tepung beras. Penambahan rumput laut pada pembuatan mie basah diharapkan dapat meningkatkan nilai gizi kepada masyarakat karena rumput laut mengandung yodium dan kadar serat yang tinggi. Penggunaan rumput laut juga mempengaruhi karakteristik mie basah yang dihasilkan. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) faktorial. Faktor yang diteliti yaitu pengaruh konsentrasi rumput laut dan jenis tepung. Faktor konsentrasi rumput laut (R) terdiri atas 3 taraf yaitu R1 = 30%, R2 = 35%, dan R3 = 40%. Faktor jenis tepung (T) terdiri atas 2 taraf yaitu T1 = tepung terigu dan T2 = tepung beras. Kualitas mie basah terbaik yang dihasilkan berdasarkan metode rangking diperoleh pada konsentrasi 30% rumput laut dan tepung terigu dengan karakteristik sebagai berikut: rendemen 176,03%, kadar protein 18,53% , nilai organoleptik warna = 3,92 (suka), nilai organoleptik aroma = 3.73 (suka), nilai organoleptik rasa = 3.78 (suka), nilai organoleptik kekenyalan = 3,95 (suka), dan nilai organoleptik uji mutu hedonik kekenyalan = 3,87 (kenyal). Kandungan yodium dari mie basah dari 3,8 mg bahan iod/100g diperoleh dari rumput laut dengan perlakuan konsentrasi 30% dan penggunaan tepung terigu (R1T1).Effect of Seaweed (Eucheuma Cottonii) and Flour Type Concentrations on Wet Noodle ProcessingABSTRACT. Type of seaweed that is usually processed into food and ready to eat is Gellidium sp. and Eucheuma sp. Diversification of processed seaweed is one of the efforts to improve the effectiveness and economic value of seaweed. It is by processing seaweed of Eucheuma cottonii into wet noodle. Wet noodle is made from flour mixed with other additives. Flour that often used in wet noodle processing is flour and rice. The addition of seaweed on a wet noodle making is expected to improve the nutritional value for society because seaweed contains iodine and high fiber. The use of seaweed also affected the characteristics of a wet noodle. The research was conducted using completely randomized design (CRD) factorial. Factors studied were the influence of the concentration and type of seaweed flour. Seaweed concentration factor (R) consisted of 3 levels, R1 = 30%, R2 = 35%, and R3 = 40%. Factors in the type of flour (T) consisted of two levels, T1 = T2 = flour and rice flour. The quality of best wet noodle generated based on ranking method, obtained at a concentration of 30% seaweed and wheat flour with the following characteristics: yield 176.03% , 18.53% protein content, color organoleptic value = 3.92 (like), aroma organoleptic value = 3.73 (like), a sense of the organoleptic value = 3.78 (like), organoleptic value of elasticity = 3.95 (like), and the value of organoleptic quality test hedonic elasticity = 3.87 (chewy). Iodine content of 3.8 mg of wet noodles iod/100g material derived from seaweed by treatment with 30% and the use of wheat flour (R1T1).

This study presents an analysis of the optimization by using HOMER software and financial viability of 10 kW wind turbine generator (WTG) through grid connected system for six different locations in Malaysia (Mersing, Kuching, K.Trengganu, Kudat, Melaka and Labuan). Assessment criteria comprised Total Net Present Cost (TNPC), and Cost of Energy ( COE ). The HOMER ( National Renewable Energy laboratory, US) was utilized as the assessment tool with modeling performed with hourly load data input from six cities in Malaysia. The results demonstrate that WTG has the potential to supply significant power for small scale load in conjunction with the grid-electricity supply. Optimization modeling demonstrated that the TNPC for grid connected configuration is Mersing for the lowest TNPC among the other cities which is TNPC recorded at $ -28,436 and initial cost is about $ 20,000. This mean wind grid system in Mersing is very benefit be built and reduction in greenhouse gas emission of 9,452 kg/yr.
