This research is a descriptive study that aimed to provide information of (1) percentage of students’misconceptions, not understanding the concept, and understanding the concept (2) factors causingmisconception (3) sub-concept with the highest misconception on concept of genetic substance using three tiertest. Population in this research is all student of class XII SMAN 2 Makassar, sample of research is student ofclass XII IPA 1 counted 35 people. The instrument used is three tier test which amounts to 25 items. Data wereanalyzed descriptively by using the category made by Pesman and Eryilmaz to determine students’understanding. Students were observed and interviewed to obtain data about factors that caused misconception.The result of data analysis of three tier test showed that 29.94% experienced misconception, 42.29% do notunderstand concept, and 27.77% understand concept. The highest percentage of students’ misconceptions isfound in the gene and allele sub concept by 57.15%. Factors that causing misconception are student that havewrong reasoning due to incomplete information, lack of interest in learning certain concept, the absence ofteacher confirmation after learning process, teacher that describing concept too fast, and text book that used inlearning process contain several misinformation.

A house garden is potential to be managed for thecultivation of vegetables for the fulfillment of nutrition and arelative reduction in the cost of living of poor families. Thecondition of the land and the limited knowledge and life skillsof the poor in the Maritengngae District, Sidrap Regency,became the main limiting factor for the use of the garden forcultivation. The Community Service-Learning and CommunityEmpowerment activity program (KKN = PPM) of UNMorganized program for target families to provide knowledgeand skills in the manufacture of organic fertilizers andcultivation of hydroponic systems. The goal was achieved byusing training methods, demonstration plots and mentoring.The activities that were realized included: a) increasedknowledge and skills of target residents in making organicfertilizer from household waste, and vegetable cultivation ofhydroponic systems; and b) fulfillment of the need for severaltypes of vegetables through utilization of the garden forcultivation. If this activity is sustainable and well developed,then the needs for the vegetable foodstuffs of the targetresidents will be fulfilled independently.

Penelitian ini bertujuan untuk mengetahui pengaruh variasi formulasi pakan Black soldier fly (BSF) Hermetia illucens yang terdiri dari limbah ikan dan sayuran terhadap kandungan nutrisi larva BSF. Jenis penelitian ini adalah eksperimen dengan menggunakan 4.000 larva BSF yang telah memasuki fase instar dua. Pemeliharaan larva BSF dilakukan selama 15 hari. Pemberian pakan dilakukan sekali dalam 2-3 hari. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 3 perlakuan dan 3 kali ulangan. Perlakuan A yaitu 10% limbah ikan : 90% limbah sayuran, B yaitu 20% limbah ikan : 80% limbah sayuran, C yaitu 30% limbah ikan : 70% limbah sayuran. Parameter yang diamati yaitu Kandungan nutrisi dalam tubuh larva BSF dianalisis menggunakan analisis proksimat. Data hasil analisis proksimat dianalisis menggunakan analysis of variance (ANOVA) dan Uji lanjut Duncan dengan taraf kepercayaan 95%, Hasil penelitian menunjukkan perlakuan C dengan 30% limbah ikan dan 70% limbah sayur memberikan hasil yang terbaik dengan kandungan protein tertinggi dibandingkan perlakuan A dan B. Maka dapat disimpulkan bahwa variasi formulasi pakan berpengaruh signifikan terhadap kandungan nutrisi larva BSF Hermetia illucens. Kata kunci: Formulasi pakan, Nutrisi, Hermetia illucens.This study aims to determine the effect of variations in the feed formulation Black soldier fly (BSF) Hermetia illucens consisting of fish and vegetable waste on the nutritional content of BSF larvae.

Treatment A is 10% fish waste: 90% vegetable waste, B is 20% fish waste: 80% vegetable waste, C is 30% fish waste: 70% vegetable waste. The observed parameters, namely the content of nutrients in the body of BSF larvae was analyzed using proximate analysis. The data from the proximate analysis were analyzed using analysis of variance (ANOVA) and Duncan's advanced test with a confidence level of 95%, the results of the study showed that the behavior ofC with 30% of fish waste and 70% of vegetable waste gave the best results with the highest protein content compared totreatments A and B. to the nutritional content of the larvae of BSF Hermetia illucens.Keywords: Feed formulation, Nutrition, Hermetia illucens.

Adding the nutritional content of broth powder without destroying the distinctive taste of the broth can be done using pure mushroom extract and additional vegetables and spices. This study aims to determine the organoleptic characteristics and identify the chemical functional groups of glutamic acid in the best samples of oyster mushroom broth powder added with vegetables and spices. The results of the organoleptic test were tabulated in a table and then analyzed using a descriptive test. The organoleptic characteristics of the best color parameters were in treatment B1 which had a pale white color . The best treatment of aroma, texture, and taste parameters were found in the B2 treatment with a characteristic aroma of typical broth, fine powder texture, and has a distinctive taste of broth. The identification of the functional groups of secondary metabolites using the Fourier Transform Infrared (FTIR) instrumentation. Identification results with FTIR showed absorption at wave number (cm-1): 3419.74, 2934.62, 1639.56, 1409.70, 1055.55. There is N-H, O-H, C-H, C=O carbonyl group and carboxylic C-O, which identify the presence of amide compound, phenol acid, alkane, aldehydes, amid I and carboxylic acid, which are known as glutamic acid in this sample. Keywords: Organoleptic, Functional Groups Identification, Oyster Mushroom Broth Powder Why only B1 that you mentioned in color parameters?
