Identifikasi Kandungan Ekstrak Kayu Jati Menggunakan Py-GCMS
Get PDFTeak wood (Tectona grandis Lf.) in the form of sawdust a byproduct/waste from the furniture industry has a considerable amount and has not been utilized optimally. This study aims to determine the content of extractive teak wood (Tectona grandis Lf.). The method used is the hot water solubility. Muna\u27s teak wood powder weighing 4,076 g soaked in distilled water as much as 100 ml glass flask, then heated in a water bath at a temperature of 100 oC for 3 hours. The content of extractive dissolved in a liquid further characterized using Py-GCMS. Results of the analysis of Py-GCMS to extract teak wood showed concentrations of some substances, such as Carbamic acid (70,70%), mono ammonium salt (CAS) Ammonium carbamate (70,70%), Acetic acid (CAS) Ethylic acid (10,52%), Acetic acid (CAS) Ethylic acid (2,35%), Acetic acid (CAS) Ethylic acid (3,26%), and Phenol (CAS) Izal (13,17%

Get PDFThe Objective of research to acknowledge the hypothesis: outreach islamic microfinance for the poor household of agricultural sector at rural Bogor West Java. The majority of the poor community in Indonesia stay at rural areas. Lack of access credit/financing generally seen as one of the main reasons why many people remain poor. Credit/financing as a powerful instrument to help poor people break out of the vicious cycle because it has the potential to improve income and savings, consequently, enhance capital accumulation, and reinforce high incomes, but providing credit to the poor of agricultural sector in many cases is a very costly activity. Bank isn’t interest to serve it. Hopefully, islamic microfinance institutions reaches to more the poor of agricultural sector. The average loan is the most commonly used to measure the degree of microfinance institutions (MFIs) outreach to poor customer segments, but it is very simple. Using the CGAP (Consultative Group to assist the poorest) method, the poverty multidimension of islamic microfinance outreach was measured. The result of study showed that islamic MFIs didn’t reach the poor household of agricultural sector at rural Bogor West Java
Karakteristik Proksimat dan Organoleptik Ubi Jalar Merah (Ipomea batatas (L.) Lam.) Pada Berbagai Proses Pemasakan
Get PDFSweet potato (Ipomea batatas (L.) Lam.) is one of functional foods that can maintain and improve human health. Due to the very hard texture of red sweet potato, it cannot be consumed directly. Therefore, it requires various cooking methods in order to be more suitable for consumption. This study aimed at determining effects of various cooking methods on the proximate and sensory properties of red sweet potato. The research covers various cooking methods of red sweet potato through boiling, frying, baking, steaming, and one treatment without cooking process (fresh) which was used as a control. The results show that various cooking methods affect almost all testing parameters significantly, except for ash content. Baked red sweet potato has the lowest moisture content (38,75%) and the highest sugar value as sucrose (17,17%). Sensory properties test results show that the most preferred red sweet potato is fried red sweet potato
Biologi Reproduksi Ikan Belida (Notopterus notopterus Pallas, 1769) di Kolong-Bendungan Simpur, Pulau Bangka
Get PDFThe knowledge of fish reproduction is the most important in freshwater management continously. The research was done from February-July 2013, was aiming to describe information on reproductive aspects of belida fishes (Notopterus notopterus),i.e. sex ratio, gonado somatic stages, gonado somatic index, first size of maturity, fecundity, and spawning type. The fish Samples was taken by gill net which had many sizes such as 2, 2.5, 3, and 4 cm. Each gill net has length 30 m and width 2 m. Belida fishes have caught during research amounted 497 ind, which consisted of: 237 male and 260 female. Sex ratio male and female fish were relatively balance. The maturity gonad of male fish is faster than female fish. Featherback do spawn every month for each observation during the research. The spawning type of Featherback is partial pattern (step by step). The first size of maturity gonad from male fish was in length 135 mm and female fish was in length 162 mm. Fecundity of Featherback was in range 1.051-6.057 eggs. Fecundity is not influenced by length or weight body. For the sake to keep Featherback population needed a regulation, such as: the mesh size regulation of gillnet have to 30 mm or equal with 1.5 inci

Get PDFBiofertilizer is a substance which contains microorganism and promotes plant growth by increasing the soil nutrient availability. The aim of this study was to analyze the growth and production of lowland and upland rice by using the biofertilizer in acid soils. Seven isolates of bacteria were used as biofertilizer, i.e. Bacillus sp., two strains of Pseudomonas sp., two strains of Azospirillum sp., and two strains of Azotobacter sp.. The treatments of this study were without fertilization, compost, 100% NPK, compost enriched with 7 isolates, compost enriched with 7 isolates + 50% NPK, compost enriched with 4 isolates, and compost enriched with 4 isolates + 50% NPK. The results showed that biofertilizer in compost improved nutrient content in acid soil, and increased rice growth and production as well. Compost enriched with 7 isolates 50% NPK showed the highest rice yield production both in the lowland and upland rice. The biofertilizer could reduced 50% utilization NPK fertilizer dosage in the first growing season
