Abstract

Background: Sustainable Reserve Food Garden Area (KRPL) is program that to increase family dietary diversity, such as children. Children’s dietary diversity can affect to nutritional adequacy and can impact to growth process. The factor that can affect successful of KRPL program is parents’ education level.Objectives: The purpose of this study was to identify the difference between children’s dietary diversity level, household income level, and parents’ education level in sustainable reserve food garden area (KRPL) and non KRPL household in Kamal sub-district, Bangkalan district, Madura.  Method: This was an observational study with case control comparative study design was conducted among 25 children in KRPL area and 25 children in non KRPL area with mother or other family member as respondents. Simple random sampling method was used to select the samples. Children and parents’ characteristic were asked to answer structured questionnaire. Children dietary diversity level was asked by Individual Dietary Diversity Score (IDDS) instrument. The data was analyzed with Mann Whitney statistic test. Result: Children that involved in this study, either in KRPL or non KRPL area, was less than the same 35 months old (52%). Children from KRPL area was mostly girls (64%), while children from non KPRL area was mostly boys (56%). Children dietary diversity condition in KRPL area was low (52%), while children dietary diversity level in non KRPL area was sufficient (64%). Children who lived in KRPL area not always have diverse intake. The result showed that there was no difference between children dietary diversity level in KRPL and non KRPL area (p=0.259). Household income level on KRPL area was higher (68%) if compared to household on non KRPL area (44%). Parents’ education level in KRPL area was classified high (father=88%, mother=88%), while that parents’ education level in non KRPL area classified low (father=88%, mother=100%) (p=0.000). Parents in KRPL area have higher education level compare to parents in non KPRL area. Conclusion: Children dietary diversity in KRPL area are not different with non KRPL area. Children who lived in KRPL area not always have diverse intake. There is difference between household’s income level and parents’ education level. Household in KRPL area have higher income and parents in KRPL area have higher education level compare to households and parents in non KPRL area. ABSTRAKLatar Belakang: Kawasan Rumah Pangan Lestari (KRPL) merupakan program yang bertujuan untuk memperbaiki dan meningkatkan keragaman pangan keluarga, salah satunya balita. Keragaman pangan pada balita dapat berpengaruh pada kecukupan kebutuhan gizi dan berdampak pada proses pertumbuhannya. Salah satu faktor yang dapat mempengaruhi keberhasilan program KPRL adalah tingkat pendidikan orang tua.Tujuan: Tujuan dari penelitian ini adalah untuk mengidentifikasi perbedaan tingkat keragaman pangan balita dan tingkat pendapatan keluarga, dan tingkat pendidikan orang tua di rumah tangga Kawasan Rumah Pangan Lestari (KRPL) dan non KRPL Kecamatan Kamal, Kabupaten Bangkalan, Madura.Metode: Penelitian observasional dengan rancang bangun penelitian potong lintang komparatif dilakukan pada subjek penelitian yang terdiri dari 25 balita di wilayah KRPL dan 25 balita di wilayah non KRPL dengan ibu atau anggota keluarga lainnya sebagai responden. Metode simple random sampling digunakan untuk memilih sampel. Karakteristik balita dan orang tua ditanyakan melalui kuesioner. Tingkat keragaman pangan balita ditanyakan melalui instrumen Individual Dietary Diversity Score (IDDS) Data dianalisis menggunakan uji statistik Mann Whitney.Hasil: Balita yang terlibat dalam penelitian ini, baik di area KPRL maupun non KPRL, sebagian besar berusia kurang dari sama dengan 35 bulan (52%). Balita yang berasal dari wilayah KRPL sebagian besar perempuan (64%), sedangkan dari wilayah non KPRL sebagian besar laki-laki (56%). Kondisi tingkat keragaman pangan balita di wilayah KRPL tergolong rendah (52%), sedangkan tingkat keragaman pangan balita di wilayah non KRPL tergolong cukup (64%). Balita yang tinggal di rumah tangga KRPL tidak selalu mengonsumsi makanan yang beragam. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan tingkat keragaman pangan balita di wilayah KRPL dan non KPRL (p=0,259). Tingkat pendapatan keluarga balita di wilayah KRPL lebih tinggi (68%) apabila dibandingkan dengan wilayah non KPRL (44%). Tingkat pendidikan orang tua di wilayah KRPL tergolong tinggi (ayah=88%, ibu=88%), sedangkan tingkat pendidikan orang tua di wilayah non KRPL tergolong rendah (ayah=88%, ibu=100%) (p=0,000).Kesimpulan: Tingkat keragaman pangan balita di area KRPL tidak berbeda dengan balita di area non KPRL. Terdapat perbedaan tingkat pendapatan keluarga dan tingkat pendidikan orang tua balita. Keluarga di wilayah KRPL memiliki tingkat pendapatan yang lebih tinggi dan orang tua di area KRPL memiliki tingkat pendidikan lebih tinggi apabila dibandingkan dengan rumah tangga dan orang tua di wilayah non KPRL.

Abstract

Rice  fields are one of the main sources of high nitrous oxide N2O emission.  Soil denitrifiers possessing high N2O reduction activity are important for controlling N2O emission.  Nitrous oxide reduction is the last step of denitrification process.  The aims of this study were to characterize and to identify denitrifying bacteria isolated from rice soils possessing high activity of N2O reduction.  Soil samples were taken from 6 locations of rice fields in Bogor (West Java) and Tangerang (Banten), Indonesia.  Physiological characterization was performed using API 20 NE, while molecular identification was conducted based on the 16S rRNA gene sequence.   It was found that ten isolates of denitrifying bacteria were able to grow using N2O as an electron acceptor as indicated by decreasing N2O concentration in the headspace of the cultures.  The bacterial  growth indicated by optical density,  increased up to 0.12-0.47  after 5 days incubation.  Isolate BL2 had the highest activity of  N2O reduction followed by BL1 and BLN1 at up to 5.41, 4.09, and 3.91 μmol mL-1 bacterial cultures, respectively.  The BL1, BL2, and BLN1 isolates had some different physiological characteristics.  Based on their 16S rRNA sequence, BL1 and BLN1 were closely related to Ochrobactrum anthropi ATCC 49188 with similarity of 99%.

Abstract

One of the promising biofuel is bioethanol which can be produced from agricultural waste cellulosic biomass such as citrus fruit waste. Bioethanol can be derived from citrus fruit waste that is rarely used. Cellulosecontained in citrus fruit  waste can be converted into ethanol through a process of chemical and biological. Sulfuric acid ( H2SO4) can be used in hydrolysis of cellulose material in citrus fruit waste to producesugars and batch fermentation by Saccharomyces cereviseae can be used to convert sugars into bioethanol.The purpose of this research were to determine the highest reducing sugar from acid hydrolisis with different acid concentration levels of 0, 3, 7, and 10% and to know the highest levels of bioethanol and optimum incubation time. Extracts made from citrus fruit waste without peel. Citrus fruits were hydrolyse using a variation of 1 M H2SO4 acid concentration of 0, 3, 7, and 10 % to produce reducing sugars. Reducing sugars were analyzed using the Nelson Somogyi method.The optimum reducing sugar is used for fermentation by yeast Saccharomyces cerevisiae using a variation of the long incubation days 0, 2, 4, 6, 8 and bioethanol purified by distillation method. Acid hydrolysis resulted reduction sugar 3,5%, at an optimum concentration of 3% is used for fermentation by yeast S. cerevisiae. The highest level of fermentation time of 6 days produced bioethanol having the content 9,75% .  Kata Kunci : Bioethanol, Citrus Acid Waste, Saccharomyces Cerevisiae, Fermentation .

Abstract

AMIK BSI Jakarta is the largest vocational education in Indonesia. Currently, AMIK BSI Jakarta has three (3) courses: Computerized Accounting, Information Management, and Computer Engineering. AMIK BSI has 15.133 active students. Of the many students have a background in different schools. After graduating from high school, the students wanted to go to college to continue their education even higher, but after entering college students are experiencing difficulties because it was not able to follow the lessons and find one of the majors, as a result of these students through college with no spirit and not serious. We need logic to solve the problem, and the need to support a decision in the selection process the selection of majors and giving recommendations courses according to the parameter by using fuzzy logic Mamdani method to determine the relationship of the determination of academic study programs. Reasons for using fuzzy logic Mamdani method for decision support.
