APLIKASI TEKNOLOGI BIOGAS GUNA MENUNJANG KESEJAHTERAAN PETANI TERNAK Dewi Hastuti
MEDIAGRO Vol 5, No 1 (2009)
Publisher : Universitas Wahid Hasyim

Pengoptimalan peran ternak terhadap pendapatan dengan menggunakan kotoran ternak sebagai bahan biogas merupakan pilihan yang tepat. Dengan teknologi sederhana ini, kotoran ternak yang tadinya hanya mencemari lingkungan dapat diubah menjadi sumber energi terbarukan yang sangat bermanfaat. Biogas adalah gas mudah terbakar (flammable) yang dihasilkan dari proses fermentasi bahan-bahan organik oleh bakteri bakteri anaerob (bakteri yang hidup dalam kondisi kedap udara). Pada dasarnya semua jenis bahan organik bisa di proses untuk menghasilkan biogas, namun demikian hanya bahan organik (padat, cair) homogen seperti kotoran dan urine (air kencing) hewan ternak yang cocok untuk sistem biogas sederhana. Biogas merupakan salah satu solusi teknologi energi untuk mengatasi kesulitan masyarakat akibat kenaikan harga bahan bakar minyak (BBM), teknologi ini bisa segera diaplikasikan, terutama untuk kalangan masyarakat pedesaan yang memelihara hewan ternak sapi. Biogas yang menggunakan bahan kotoran ternak menghasilkan api berwarna biru bersih, tidak menghasilkan asap maupun bau sehingga kebersihan dapur terjaga. Biogas dapat digunakan 24 jam nonstop tidak akan berhenti sepanjang bahan baku kotoran ternak rutin dipasok ke dalam digester. Untuk memasak air dengan biogas membutuhkan waktu 15 menit lebih cepat dibandingkan menggunakan kayu bakar atau minyak tanah. Biaya menjadi lebih irit. Keluarga yang sudah menggunakan biogas tidak membutuhkan pembelian bahan bakar karena sudah bisa terpenuhi kebutuhannya dari kotoran ternak yang dipeliharanya. Teknologi biogas dapat diterapkan pada skala rumah tangga dengan asumsi rata-rata kepemilikan ternak sapi ditiap rumah 2 ± 3 ekor. Satu ekor sapi bisa menghasilkan rata-rata 23,59 kg kotoran per hari. Dengan mengeluarkan biaya Rp. 1,5 juta untuk membeli satu unit alat biogas, bisa melakukan penghematan dalam tahun pertama adalah Rp. 552.960, sedangkan tahun berikutnya mendapat keuntungan sebesar Rp. 1.037.540 dikurangi total biaya perawatan/tahun. Menerapkan teknologi baru kepada masyarakat desa dilihat dari aspek sosio kultural merupakan suatu tantangan tersendiri akibat rendahnya latar belakang pendidikan, pengetahuan dan wawasan yang mereka miliki. oleh karena itu diperlukan sosialisasi yang terus menerus. Apabila secara ekonomi tidak menguntungkan masyarakat maka aplikasi teknologi tersebut akan gagal. Aplikasi biogas menjadikan kotoran ternak sangat berharga, oleh karena itu para petani akan rajin merawat ternaknya sehingga kondisi kandang menjadi bersih dan kesehatan ternak menjadi lebih baik. Secara tidak langsung akhirnya akan membawa keuntungan dengan penjualan ternaknya yang sehat, lebih cepat besar dan harga jualnya menjadi lebih tinggi.

This research was conducted to evaluate the bacterial contamination in fresh milk from farmers, milk collectors, and dairy cooperative (KUD) in Getasan Subdistrict, Semarang Regency. The evaluation of bacterial contamination has been observed by the number of bacteria, milk distribution time, reductation test, alcohol test and pH test of fresh milk samples which had been taken from 30 farmers, 30 milk collectors and 4 dairy cooperatives in Getasan Subdistrict. The result showed that in the farmers, there is 1 positive alcohol test from 30 samples, pH 6, reductation time of 7 hours, and has total bacteria 3.01 × 105 cfu / ml milk. The alcohol test of the milk from collectors also show 1 positive result from 30 samples with pH 6, reduction time of 6 hours and has total bacteria 6.17 × 105 cfu / ml milk. While in alcohol test of dairy cooperative shows 2 positive result, from 4 samples with pH 6, reductation time of 5 hours and has total bacteria 1.38 × 106 cfu / ml milk. The duration of milk distribution from farmer to KUD were 111 minutes. Thus, it is concluded that microbiological quality of milk in farmers and milk collectors level is good because it is below the maximum limit of total bacteria according to Indonesian Standart, but the amount of bacteria milk contamination in dairy cooperative is high due to the duration of distribution (111 minutes) without cooling.Keywords: bacterial count, milk quality, milk safety, distribution time

Population growth will be followed by the fulfillment of a residence or settlement so that it will trigger a land conversion. Land conversion or land conversion is defined as a change in the function of part or all of the land area from its original function (as planned) to other functions that have negative impacts (problems) on the environment and the potential of the land itself. According to BPS (2001) in a period of 7 years (1993-2000) there was a reduction in Indonesian agricultural land by 710,000 ha or 56.167 ha per year. As the population in Indonesia increases, it is followed by a decrease in the area of agricultural land due to the process of land conversion to meet residential needs. Land conversion that is carried out directly or indirectly, can be temporary or permanent, can be in the form of gradual conversion with a sporadic pattern, systematic conversion with an “enclave” pattern, land conversion in response to population growth, conversion caused by social problems, conversion without burden and Agricultural adaptation conversion Land conversion is influenced by external factors including economic, socio-cultural, increasing population and regulations, while internal factors such as less productive land and economic pressure from farmers. Conversion of agricultural land has a positive impact in the form of increased investment in the non-agricultural sector but has a negative impact on threatening national food security and decreasing environmental quality.

Tea shoots processing intended to alter the chemical composition of fresh tea shoots, so bring the desired properties. Freshly plucked tea leaves containing water 75% of the weight of the leaves. The water contained in the leaves removed through the process of withering and drying in the processing of green tea. Green tea liquid waste obtained from the milling process and not used optimally, it needs a touch technology that can turn liquid waste into useful liquid organic fertilizer. The use of an activator / starter (micro-organisms) in green tea liquid waste is an alternative technology to improve the health and fertility of the soil and plants. The purpose of this study to determine the benefits of using liquid waste of green tea on the growth of tea seeds. Results of analysis of the utilization liquid waste of green tea with the addition of starter (EM-4) has not shown any real effect on the percentage of seedling growth and seedling growth (plant height, number of leaves and greenery).

SUMPENA.2011.To Determine the effect of Packing and Storage Method on the Viability of Cucumber Seed. Following reports poor Cucumber seed germination from farmers who had been sent seed, a laboratory experiment was conducted to determine the effect of storage period and packing method on the viability of four cucumber variety. The experiment was conducted at LEHRI from January 2010 to December2010. A Split Plot Design with three replications was used with packing method as the main plot and storage period as the subplot. After 6 mount Cucumber seed germination (82%) was significantly higher when stored at room temperature in vacuum packed alumunium foil sachets, than all other packing methods. The percentage of Cucumber seed which around 60% after 4 mount to 21% and 10% after 6 mounts respectively. When first tested, the Venus variety exhibited significantly lower germination (63%) than the other varietys which ranged from 86-98%. Key word; Storage, packing, cucumber seed, viability.

Tujuan dari penelitian adalah untuk menggetahui pengaruh pemangkasan dan dosis kompos pada pertumbuhan dan produksi tanaman mentimun (Cucumis sativus L.). Penelitian dilakukan pada februari – juni 2021 di Greenhouse Fakultas Peternakan dan Pertanian Universitas Diponegoro. Rancangan menggunakan rancangan faktorial acak lengkap 3 x 3 dengan 4 kali ulangan. Faktor pertama adalah pemagkasan yang terdiri dari 3 taraf yaitu tanpa pemangkasan (P0), pemangkasan pucuk (P1) dan pemangkasan cabang lateral (P2). Faktor kedua adalah dosis kompos yang terdiri dari 3 taraf, 15 ton/ha (K1), 30 ton/ha (K2) dan 45 ton/ha (K3). Data dianalisis menggunakan analisis ragam. Data yang signifikan dilanjutkan uji jarak berganda (Duncan) 5%. Hasil menunjukkan bahwa jumlah daun, jumlah buah, berat total buah signifikan dipengaruhi oleh dosis kompos. Parameter waktu muncul bunga memberikan hasil signifikan yang dipengaruhi oleh pemangkasan, dosis kompos dan interaksi dari perlakuan. Parameter luas permukaan daun memberikan hasil signifikan yang dipengaruhi oleh pemangkasan. Panjang tanaman, dan panjang buah tidak dipengaruhi oleh perlakuan yang diberikan
