Pengaruh Oksigen Pada Akumulasi Poly Hydroxy Alkanoates (PHA)
Get PDFPolyhydroxyalkanoates (PHA) adalah salah satu contoh dari bioplastik. PHA disintesis oleh bakteri sebagai karbon atau komponen simpanan energi ketika jumlah intake karbon berlebihan dan beberapa nutrisi seperti nitrogen, phospor, dan oksigen dalam kondisi yang terbatas. Pemberian aerasi oksigen sangat mempengaruhi produksi dan akumulasi PHA. Tingkat aerasi oksigen yang rendah akan meningkatkan konsentrasi PHA. Penetapan suplai oksigen pada batas level tertentu yang tepat akan dapat meningkatkan produktivitas atau akumulasi PHA, tanpa mengganggu pertumbuhan mikroorganismeKata kunci: polyhydroxyalkanoates, bioplastik, oksigen, bakter
Effect of Gum Ashitaba (Angelica keiskei) on Slaughter Weights, Carcass Weights and Physical Quality of Broiler Meat
Get PDFAshitaba (Angelica keiskei) is an herbal plant that has many functions for the body. The purpose of this study to determine the increase in slaughter weight, carcass weight and physical quality of broiler meat. This study used 20 broiler chickens were grouped into 4 groups and each consisting of five chickens. The study design is completely randomized design (CRD) with design Randomized Post Test Only Control Group Design. The real difference between treatments was tested further using Duncan test. The study consists of four treatment that P1 (negative control without given any treatment, P2 ( positive control treatment with vitamin, antibiotics, vaccines and supplements), P3 (sap Ashitaba 2 ml/liter of water, and P4 (sap Ashitaba 4 ml/liter of water). The results showed that administration of sap Ashitaba a dose of 2 ml/liter can improve pH (p <0.05) but did not affect slaughter weight, carcass weight, water holding capacity and cooking losses broiler meat.

Analisis Kecenderungan Mengkonsumsi Marjinal dan Faktor-Faktor Yang Mempengaruhi Konsumsi Masyarakat Jawa Timur
Get PDF ABSTRACTThe purpose of this research is (1) to know the macro economic factors that influence the consumption of East Java society, (2) to analyze the marginal propensity to consume, (3) to discuss the consumption pattern of the East Java community. Multiple linear regression method is used to answer the first objective, the second objective is calculated using the MPC formula, while the third goal is analyzed through consumption expenditure table. The result of the research shows that income and interest rate influence the consumption of East Java society with coefficient value of 0,827 and 0,334 respectively. This shows that if there is increase of income and Interest rate of 1% then consumption will increase by 0.827 and 0.334. The value of East Java MPC ranges from -0.004 - 0.57 to an average of 0.240 (24%), this show that 24% of East Java's income is used for consumption, while the remaining 76% is used for consumption purposes. East Java community consumption pattern shows consumptive pattern to non food consumption with percentage equal to 54,12%. Keywords: East Java, Consumption, MP

Produksi dan Komposisi Susu Kambing Peranakan Ettawa Melalui Pemberian Ekstrak Meniran
Get PDFThis research was conducted to determine the difference in quantity and quality (specific weight, fat, protein, total solid, total solid non fat, fatty acid omega 6 and 3) of milk in ettawa goat fed meniran extract (Phyllanthus niruri). Experimental animals used in this study were 12 peranakan ettawa goat that were producing at the second lactation with average body weight of 50 kg and milk production about 1-2 liters. They were divided into four groups, each groups containing 3 animal. Group 1 (without meniran extract), group 2 (50 mg meniran extract/kg body weight), group 3 (100 mg meniran extract/kg body weight), and group 4 (150 mg meniran extract/kg body weight). Quality of milk calculated at the end in research and quantity of milk calculated every day twice a day in the morning and evening. The data obtained in the study were analyzed with ANOVA. The results showed there were significant difference (p<0,05) in feed consumption, milk quantity, but not at milk quality (specific weight, protein, total solid non fat) of Peranakan ettawa goat fed meniran extract.

The Variance of Strong Acid and Long Time Soaking Solutions on Quality of pH and Protein Gelatin of Sheep Skin
Get PDFThis study aims to determine the quality of pH and sheep skin gelatin protein that is hydrolyzed using strong acid. The main ingredient of this research is sheep skin originated from Brebes Regency which is 1 - 2 years old. The research method used Randomized Completely Randomized Design (RAL) 2 x 3 factorial pattern where the first factor is soaking material (HCl 2% v / v and H2SO4 2% v / v) and second factor is the duration of immersion (2 hours, 3 hours and 4 hour), then continued with the real difference test using Duncan Multiple Range Test (DMRT). The test results showed sheep skin gelatin value that is pH 3,52 - 3,85 and protein 88,80 - 90,47%. HCl 2% ability to hydrolyze sheep skin collagen is better than 2% H2SO4. Highest pH and protein values occur at 4 hours of soaking time
Percepatan Alih Fungsi (Konversi) Lahan Pertanian Ke Non Pertanian di Kecamatan Galis Kabupaten Pamekasan
Get PDFKecamatan Galis Kabupaten Pamekasan memiliki perbandingan luas lahan pertanian dan non pertanian sebesar 50%. Rencana Strategis Kabupaten Pamekasan tahun 2012 - 2032, kecamatan Galis direncanakan menjadi pemukiman perkotaan. Dengan persentase lahan pertanian tersebut, jika terus terjadi pembangunan yang merelakan lahan pertanian produktif sebagai sasarannya, dikhawatirkan lahan pertanian produktif akan habis dan mengakibatkan kecamatan Galis mengalami rawan pangan. Tujuan penelitian adalah menganalisis perkembangan alih fungsi lahan dari tahun 2006-2016 dan menganalisis hubungan antara faktor ekonomi, faktor sosial dan peran pemerintah terhadap alih fungsi lahan. Penentuan lokasi dilakukan secara sengaja (purposive). Metode penelitian menggunakan analisis deskriptif dengan pendekatan tabulasi silang chi square. Hasilnya adalah faktor - faktor yang memiliki hubungan terhadap alih fungsi lahan yaitu produktivitas lahan; peruntukan lahan, asal lahan, perubahan perilaku, hubungan lahan dengan pemilik; dan pengurusan izin. Selama tahun 2009 – 2015 terjadi perubahan fungsi lahan tegal menjadi pemukiman pada tahun 2011 sebesar 1,46 Ha yang digunakan untuk tempat tinggal, tempat usaha dan layanan umum. Saran dari penelitian ini adalah pemerintah perlu menjaga perilaku petani dengan lebih persuasif tentang pertanian agar tidak mengalihfungsi lahan; Adanya peraturan tentang pembatasan penggunaan lahan pertanian dan nonpertanian; Mempersulit izin alih fungsi lahan pertanian ke nonpertania
Perbandingan Warna Tepung Suweg Fase Dorman dan Vegetatif Secara Instrumental dan Sensoris
Get PDFThe color of the flour has an important role because it will happen to the resulting derived product. This study was to compare the color of suweg flour produced from the dormant and vegetative phases in instrumental and sensory. Instruments using Chromameter. Parameters observed from L *, a *, b *, chroma, and hue degrees. Sensory testing uses a rank test of color preferences, brown color and color brightness. The results showed significant differences in L *, a *, b *, and chroma values between dormant and vegetative phase flours. The degree value of hue was not significantly different between the two treatments. Panellists stated 100% liked the color of the dormant flour stage than vegetative.Additionally, the color of the vegetative phase flour was assessed by more than 80% of the panelists claiming to be more brown and more than 90% of the panelists stated darker than dormant. Pearson correlation test results show that there are correlation in some parameter of instrument and sensory. Keywords: suweg flour, color, dormant, vegetative, chroma, hu
