Judul: Ketahanan Pangan Rumah Tangga Petani di Tasikmalaya dan Garut, Jawa Barat
Abstrak: Ketahanan pangan merupakan isu pokok dalam pemenuhan kesejahteraan masyarakat karena akan menentukan kestabilan ekonomi, sosial, dan politik dalam suatu negara. Penelitian ini menganalisis status ketahanan pangan rumah tangga petani, juga menguji determinan ketahanan pangan rumah tangga petani tersebut. Penelitian dilakukan di Tasikmalaya dan Garut, Jawa Barat. Data penelitian ini diambil dari 209 rumah tangga petani yang dipilih secara purposive sampling, menggunakan kuesioner yang terstruktur. Teknik analisis statistik deskriptif dan analisis regresi tobit untuk mengidentifikasi faktor-faktor yang memengaruhi ketahanan pangan rumah tangga digunakan dalam penelitian ini. Hasil menunjukan bahwa indeks ketahanan pangan rumah tangga dipengaruhi oleh usia kepala rumah tangga, jenis kelamin kepala rumah tangga, konsumsi beras miskin (raskin), dan akses kredit. Oleh karena itu, penelitian ini merekomendasikan pemerintah dan perusahaan swasta lainnya untuk meningkatkan ketahanan pangan rumah tangga petani melalui peningkatan kualitas raskin, mencari alternatif bantuan (subsidi) makanan yang lebih baik untuk masyarakat petani, dan meningkatkan akses mereka terhadap kredit dengan cara meminimalisir kendala kredit rumah tangga. Indikator ketahanan pangan juga harus ditinjau kembali sehingga tidak menciptakan pemahaman bahwa rumah tangga yang tahan pangan haruslah rumah tangga kaya.

Judul: Peran Kelompok Tani dalam Ketahanan Pangan Rumahtangga Petani (Desa Banjarsari dan Desa Tanjungsari, Kecamatan Sukaresik, Kabupaten Tasikmalaya, Propinsi Jawa Barat)
Abstrak: The purpose of this study was to identify the level of household food security of farmers who have been realized, analyze factors that affect household food security of farmers and formulate farmer groups roles in farmers households to achieve food security. Research approach design by survai, the reasearch respondents were 60 head of household the members of farmer farmer group from Banjarsari and Tanjungsari villages, Sukaresik District, Tasikmalaya District, West Java Province. The research uses quantitative and qualitative statistical method with Rank Spearman Correlation to examine variables. Results from the study showed that farmers' household food availability is adequate but is not stable when the season facing famine, drought or shortly before harvest. Need to increase the role of farmer groups to achieve household food security of farmers.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
