A short review on adverse effect of eating african sharptooth catfish (clarias gariepinus)

Despite government orders to close farms and kill stocks for fear that the fish could endanger the local faune, Indian seafood farmers continue to breed catfish. Records reveal that many farmers in small villages also harvest small fish called Clarius garipinus. Without official approval, the fish were brought to the country. After hearing concerns that the fish were a danger to indigenous ecosystems, the government first implemented the ban in 2000. Other complaints say that farmers use chicken waste as foodstuffs and pollute the water supply. The government and the high court ordered all stocks to be demolished and farms to be closed.

Pemanfaatan Pelepah Sawit dan Kotoran Ayam Ras untuk Pembuatan Pupuk Bokashi pada Kelompok Wanita Tani Padang Baru Babatan, Seluma, Bengkulu

The Utilization of Oil Palm Midrib-leaf and Chicken Manure for Making Bokashi Fertilizer in the Women's Farmers Group Padang Baru Babatan, Seluma, Bengkulu The purpose of the community service program is to utilize agricultural waste, namely oil palm midrib-leaf and chicken manure which are often found in this Babatan Village, Sukaraja Subdistrict, Seluma Regency, Bengkulu. In addition, this program was aimed to increase knowledge and skill to produce bokashi fertilizer with raw materials found around them. The methods used were lecture, demonstration plots, and mentoring. The results of the activity were the increasing of family income by making bokashi utilizing waste raw materials around their lives, namely bokashi made from palm fronds and broiler chicken waste that is ready to be sold. In limited quantities, they have been able to sell their products to meet the needs of other farmer groups or the general public in need.

Consumer and Food Product Determinants of Food Wasting: A Case Study on Chicken Meat

Food wastage is an environmental concern worldwide, particularly regarding households. This study aims to identify household food wasting segments and to assess the relationship between both consumer and food product determinants and the identified segments. Data were collected through a consumer survey of several packaged chicken products (n = 256; 2019) in a retail setting in Belgium. Of the participants, 36% reported never wasting any chicken meat. The average waste percentages were small, 1.1–3.1%, depending on the packaged product, although they were not significantly different between products. Participants with low levels of self-reported chicken waste were significantly older, without children and/or unemployed. Moreover, their households scored better for household routines and skills. They also agreed more to intend not to waste food, experienced a stronger injunctive norm and perceived consumer effectiveness. Additionally, lower chicken product wastage was discovered for households purchasing organic products and products with both a lower food convenience grade and shorter shelf life. Some relationships between household wastage and food product determinants contrast with expectations based on literature. The cause can be that some determinants are more related to food wasting (e.g., when participants buy organic products) than others (e.g., the products’ shelf life).

Cultivation of Chlorella sp. in broiler chicken waste media and its metabolite profile by GC-MS analysis

Broiler Chicken Waste (LTAB) contained Nitrogen, Phosphorus and Potassium. LTAB can be used as an alternative medium for the cultivation of Chlorella sp. In this study, Chlorella sp. was cultured in LTAB at various concentrations (2,4,6,8, and 10%). Growth of Chlorella sp. was measured based on optical density values at a wavelength of 680 nm. Biomass was extracted using chloroform. The extract obtained was identified using Gas Chromatography-Mass Spectroscopy (GC-MS). LTAB 2% was the best medium for the growth of Chlorella sp. (amongst other concentrations). The highest growth rate was on the 10th day. Based on the results of KG-MS, chloroform extract of Chlorella sp. cultured on LTAB 2% contained oleic acid, methyl ester and gamma-sitosterol.Keywords: Chlorella sp, Medium, Waste, chromatographyABSTRAKKultivasi Chlorella sp. pada media limbah ayam broiler dan profil metabolitnya dengan analisis GC-MSLimbah Ternak Ayam Broiler (LTAB) mengandung Nitrogen, Fosfor dan Kalium.

Analysis and Characterization of Solid and Liquid Organic Fertilizer from Hydrothermal Carbonization (HTC) of Chicken Feather and Blood Waste

Conversion of feather and blood from chicken slaughterhouse waste for producing solid and liquid organic fertilizer excluding composting process with a variation of the mass ratio of feather and blood of a chicken has been conducted. The nitrogen, sulfur, and iron content in the solid and liquid product of the hydrothermal carbonization process were analyzed to identify and characterize the possibility of hydrolysate as a source of nitrogen, sulfur, and iron in soil fertilizer. Feather and blood of chicken waste were introduced to a hydrothermal carbonization reactor with the addition of limestone at a temperature range of 160–170 °C for the preparation of solid and liquid organic fertilizer. According to the FTIR interpretation, the solid product had functional groups such as NH, OH, CH sp3, SH, C=O, C=C, C–O–C, and C–H aromatic. The nitrogen, sulfur, and iron content of the optimal ratio in the solid phase were 4.67%, 1.63%, and 3694.56 ppm, while their contents in the liquid fertilizer were 3.76%, 1.80%, and 221.56 ppm, respectively. The vibration of 478 cm–1 is attributed to Fe–O paramagnetic (Fe2O3) confirmed by TEM images showed the diameter size less than 20 nm indicating the presence of superparamagnetic material.
