Judul: Feasibility Study Usaha Budidaya Lebah Trigona (Tetragonula biroi) di Desa Maipi, Kecamatan Masamba, Kabupaten Luwu Utara
Abstrak: Desa Maipi merupakan salah satu desa percontohan budidaya lebah trigona dengan produksi madu yang baik. Kegiatan usaha budidaya lebah trigona memiliki peranan yang penting sebagai salah satu strategi dalam mencukupi perekonomian masyarakat sekitar. Namun, tidak semua peternak sadar akan besarnya kontribusi usaha budidaya lebah trigona yang dijalankan terhadap pendapatan rumah tangga mereka. ini (1) mengidentifikasi aspek-aspek kelayakan usaha budidaya lebah trigona di Desa Maipi; (2) menganalisis finansial Maipi; (3) menganalisis pengaruh perubahan harga dan produksi madu terhadap usaha budidaya lebah trigona. ini adalah analisis aspek-aspek kelayakan usaha dengan deskriptif, analisis sensitivitas. Hasil penelitian ini menunjukkan: (1) usaha budidaya lebah trigona memiliki kendala dalam pelaksanaannya yaitu dari keterbatasan akses pasar, pengelolaan manajemen kelompok, minimnya alat dan pengetahuan dalam budidaya. Lebah berperan positif dalam membantu meningkatkan ekonomi masyarakat, sebagai polinator dan bioindikator lingkungan. (2) Berdasarkan analisis kelayakan finansial usaha budidaya lebah trigona di Desa Maipi layak dilakukan. (3) Perubahan harga dan produksi maksimum agar usaha budidaya layak dijalankan yaitu 44,22% untuk stup di kebun dan 37,45% untuk stup di rumah, Maipi Village is one of the trigona beekeeping pilot villages with good honey production. Trigona beekeeping business activities have an important role as one of the strategies to provide for the economy of the community. However, not all beekeepers are aware of the large contribution of the trigona beekeeping business for their household income. This study aims to (1) identify the feasibility aspects of trigona beekeeping business in Maipi Village; (2) analyse the financial feasibility of trigona beekeeping business in Maipi Village; (3) analyse the effect of price and honey production changes on trigona beekeeping business. The method used in this research is descriptive analysis of business feasibility aspects, cost and benefit analysis, and switching value analysis. The result of this study indicates: trigona beekeeping business has obstacle in the implementation, from limited market access, group management, lack of tools and knowledge in beekeeping. Bees play a positive role helping improve the community’s economy, as pollinators and environmental bioindicators; (2) Based on the financial feasibility analysis trigona beekeeping business is feasible; (3) The maximum change for price and production for feasibly beekeeping business is 44,22% for stup in farm and 37,45% for stup at house.

Judul: Analisis kelayakan finansial usaha budidaya lebah madu Apis mellifera (studi kasus peternakan lebah madu sari bungan di desa Titisan kecamatan Sukaraja kabupaten Sukabumi)
Abstrak: Beekeeping is one of potential sector in Indonesia. There are a lot of advantages from beekeeping, such as beekeeping products (eg: honey, royal jelly, pollen, beaswax, propolis and apitoxin), pollinatin and crete job vacancies. Sari Bunga is one's of big apiary in Indonesia. The purpose of this research were to : 1) know about apiary management, 2) analyze financial feasibility and 3) analyze sensitivity of financial feasibility.

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.
