Abstract

Durian seed milk (Duriozi bethinus Murr) is processed from durian seeds which contains nutrients such as carbohydrates, fats, proteins, vitamins and minerals. This study aims to determine the level of public acceptance (organoleptic test) of durian seed milk. This research is a quantitative descriptive research. The object used is durian seeds made with 3 treatments, namely A1 (1 kg durian seeds + 1 liter of water), A2 (1 kg durian seeds + 2 liters of water) and A3 (1 kg durian seeds + 3 liters of water) with an assessment aspect namely aroma, taste, texture, and color. The results obtained show that durian seed milk has the highest organoleptic test value, namely in treatment A3 with an average hedonic scale value of 3.53 (likes) and treatment A2 with an average hedonic scale value of 3.33 (likes) while in treatment A1 the lowest with an average hedonic scale of 2.59 (somewhat like). The results of the study are very suitable to be used as learning media in the form of posters with a percentage of 82.48%, which is the average of the validation results of the three validators, namely content experts (70%), design experts (85.45%), media experts (92% ) and the results of the assessment by students (83.75%).

Abstract

Melinjo (Gnetum gnemon L.) merupakan salah satu tumbuhan yang terdapat di Sulawesi Tengah terutama di wilayah kota palu. Tumbuhan ini memiliki banyak manfaat mulai dari batang, daun, bunga maupun bijinya dengan kandungan zat gizi mulai dari karbohidrat, protein, lemak, maupun vitamin. Daun melinjo muda merupakan salah satu bagian tanaman melinjo yang paling sering dimanfaatkan masyarakat sebagai sayuran yang memiliki zat gizi salah satunya yaitu vitamin C, selain itu daun melinjo juga mengandung senyawa antioksidan seperti likopen dan karotenoid. Selain dijadikan sebagai sayuran daun melinjo muda juga dapat diolah menjadi produk kerupuk daun melinjo yang dapat dikonsumsi baik orang dewasa maupun anak-anak. Penelitian ini bertujuan untuk menentukan kadar vitamin C pada kerupuk daun melinjo. Penentuan kadar vitamin C ini menggunakan metode Spektrofotometri Uv-Vis. Hasil penelitian ini menunjukkan bahwa persentase kadar vitamin C kerupuk Daun melinjo pada tiap pengulangan (P1, P2, P3) yaitu 37,66% mg/100g, 37,89% mg/100g , 37,90% mg/100g dengan rata-rata 37,81% mg/100g. Hasil penelitian ini dinyatakan sangat layak dijadikan sebagai sumber belajar dalam bentuk penuntun praktikum dengan rata-rata persentase kelayakan sebesar 82,53%.

Abstract

Stingless bees are social bees that live in colonies. Indonesia has a variety of stingless bee species that can be identified based on morphological, morphometric and nest structure characters. This study aims to describe the morphological, morphometric and nest structure characteristics of Stingless bee Tetragonula biroi from Sigi Regency. This study used the roaming method to find samples in nature, with a purposive sampling technique. Obtained morphological, morphometry and nest structure data were analyzed using the Principal Component Analysis (PCA) method with PAST4 software. The morphological characters of the worker bee Tetragonula biroi have a dominant black body, blackish brown abdomen, antennae with 11 flagellomeres, black thorax, black hair standing on the mesoscutum and mesoscutellum, brownish black mandibles, with 5 hamuli. The most dominant character in the formation of seven groups of stingless bees in this study, namely Hamuli Number (HN), Fore Wing Length (FWL), and Length of Forewing Including Tegula (WL1). The nest entrance hole of T. biroi is elliptical in shape with a width of 7.1 cm and a height of 2.8 cm and is light brown in color. The internal structure of the nest of T. biroi consists of honey cells, pollen cells and stem cells. The existence of size differences in the same specimen and from different places, can be influenced by several environmental factors and is also a form of morphological adaptation.

Abstract

Stingless bees are eusocial bees belonging to the Apidae family and the Meliponini subfamily. This study aims to describe the morphological and morphometric and nest structure characteristics of Stingless bee Lepidotrigona terminata from Parigi Moutong Regency. This study used the roaming method with a purposive sampling technique. Obtained morphological and morphometry data were analyzed using the Principal Component Analysis (PCA) method with PAST4 software. The morphological characters of Lepidotrigona terminata had a dominant black body, on the thorax, black scutum and scutellum covered with brown hair and yellow packaging on the edges. The tegula is brown, the tibia on the legs is black, the hind tibia is slightly hairy (plumose), antennae with 11 flagellomeres, the number of hamuli is 8. The most dominant character in the formation of seven groups of stingless bees in this study were Hamuli Number (HN), Fore Wing Length (FWL), and Length of Forewing Including Tegula (WL1). There are differences in character size compared to the same or different species in other areas.
