Dampak Bantuan Sosial Penguatan Lembaga Distribusi Pangan Masyarakat (P-ldpm) terhadap Kinerja Gapoktan di Kecamatan Natar Kabupaten Lampung Selatan

This research aims to assess the impact of P-LDPM on Gapoktan performances and rice farmers incomes member of Gapoktan in Natar District South Lampung Regency. The sample of this research includes two Gapoktan's chairman, and 26 rice farmers from Gapoktan Pendowo (P-LDPM recipient) and Gapoktan Mekar Sari (non P-LDPM recipient). The data collection was conducted from April to May 2015. Performance of Gapoktan was analyzed by quantitative descriptive analysis; income of rice farmers was analyzed by independent t-test of two samples. The result of this research showed that P-LDPM gave impact on Gapoktan performance. This could be seen from the recipient of P-LDPM Gapoktan performance that showed a good performance, in two performance indicators set by the Ministry of Agriculture in 2013. While, non recipients P-LDPM Gapoktan only showed good performance in one indicator. Income of the farmer was not impacted by P-LDPM yet, this could be seen from the results of independent t-test of two samples analysis that showed no significant difference in the average income per hectare between recipients and non-recipients of Gapoktan members

Hasil dari penelitian ini menunjukan bahwa interaksi antara faktor level buah belimbing wuluh kering matahari dan faktor lama penyimpanan berpengaruh nyata (P<0,05) terhadap pH, oksidasi lemak (TBA), aktivitas antioksidan, total plate count (TPC). Level pemberian buah belimbing wuluh kering matahari 4,5% memberikan hasil tertinggi pada aktivitas antioksidan, dan nilai terendah pada pH, oksidasi lemak (TBA) dan total plate count (TPC). Pada level 1,5% sampai 4,5% menekan laju oksidasi lemak (TBA) dan total plate count (TPC) pada setiap lama penyimpanan hari ke 7, 14, 21 dan 28, sebaliknya pada nilai aktivitas antioksidan cenderung meningkat seiring penambahan level buah belimbing kering matahari pada lama penyimpanan yang berbeda

Estimation of temperature and electron density in stainless steel plasma using laser induced breakdown spectroscopy

LIBS plasma produced by a 1064 nm Q-switched Nd:YAG laser in an atmospheric pressure was studied for the stainless steel sample. The laser output energy 150 mJ with pulse duration of 6 ns. The plasma emission spectrum was recorded by the LR1 Spectrometer connected to the fibre optic. The plasma temperature and electron density of each element were estimated by time-resolved spectroscopy of neutral atom and ion line emission. The plasma temperature was obtained from the Boltzmann plot method and their electron density was determined by using Saha-Boltzmann equation method. The preliminary qualitative LIBS analysis shows that several elements contained in the stainless steel. The element detected was Cu, Fe, Mn, Ni, and Cr. The results shows that Mn and Fe has the highest plasma temperature of 1.2 eV, but the electron density of Mn was the highest with value 4.6x1020 cm-3, while the Cu has the lowest temperature that is 0.73 eV with the electron density 2.8x1017 cm-3. The results are discussed

Substation system simulation models for transformer risk assessment analysis

This paper comprises a study which is carried out to investigate and evaluate the effect of lightning stresses on the 132 kV substation in the way to improve its reliability in the event of active lightning activities. The paper also detailed the modelling parameters of substation for this transient analysis in order to evaluate the performance and to recommend such configuration to optimize its design to be not only to withstand the stresses but to be more cost effective. The modelling and simulation are carried out using one of the most powerful power system simulations tools that is PSCAD-EMTDC and the substation layout design is adapted from 132/11 kV Simpang Renggam -- Ayer Hitam substation, courtesy of TNB. The model is based on single phase line model as it was suggested by the IEEE to be adequate to represent the substation in transient analysis simulation. The outcome of this paper would be the results of lightning stresses in term of voltage level measured at particular points in substation. The results are then compared with the suggested BIL for assessment of transformer failure

N-(4-Methyl­phen­yl)-3-nitro­pyridin-2-amine1

Two independent mol­ecules comprise the asymmetric unit of the title compound, C12H11N3O2. These differ in terms of the relative orientations of the benzene rings as seen in the respective dihedral angles formed between the pyridine and benzene rings [17.42 (16) and 34.64 (16)°]. Both mol­ecules are twisted about the amine–tolyl N—C bonds [respective torsion angles = 22.3 (5) and 35.9 (5)°] but only about the amine–pyridine N—C bond in the first independent mol­ecule [respective torsion angles = −11.7 (5) and 0.8 (5)°]. Intra­molecular N—H⋯O hydrogen bonds preclude the amine H atoms from forming significant inter­molecular inter­actions. The crystal packing features inter­molecular C—H⋯O and C—H⋯π and π–π [centroid–centroid distance: pyridine–benzene = 3.6442 (19) Å and pyridine–pyridine = 3.722 (2) Å] contacts

2-(3-Nitro­phen­oxy)quinoxaline

In the title mol­ecule, C14H9N3O3, the dihedral angle between the quinoxaline and benzene rings is 77.13 (9)°. The mol­ecule is twisted about the ether–benzene O—C bond, with a C—O—C—C torsion angle of −102.8 (2)°. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming layers in the ab plane, with one nitro O atom accepting two such inter­actions. The layers stack along the c-axis direction via weak C—H⋯π inter­actions

2-(4-Methyl­phen­oxy)-5-nitro­pyridine

The title mol­ecule, C12H10N2O3, is twisted, the dihedral angle between the rings being 61.16 (13)°. The nitro group is approximately coplanar with the pyridine ring to which it is attached [O—N—C—C torsion angle = −178.1 (3)°]. Supra­molecular chains along [010] and mediated by C—H⋯O and π–π [centroid(pyrid­yl)–(benzene) distance = 3.8259 (18) Å] contacts feature in the crystal packing

N-(4-Chloro­phen­yl)-4-methyl­pyridin-2-amine

In the title compound, C12H11ClN2, the dihedral angle between the benzene and pyridyl rings is 48.03 (8)°. Twists are also evident in the mol­ecule, in particular about the Na–Cb (a = amine and b = benzene) bond [C—N—C—C = −144.79 (18)°]. In the crystal, inversion dimers linked by pairs of N—H⋯N hydrogen bonds result in the formation of eight-membered {⋯NCNH}2 synthons [or R 2 2(8) loops]
