Abstract

Background: In Maluku Province, especially in West Seram Regency (SBB) Taniwel District, salak plants were found with unique thick yellow flesh with a red tinge, called red salak. Negeri Riring and Negeri Buria are samples of red salak cultivation centers that are at different altitudes, allowing for differences in primary metabolite content, especially total fat content in red salak plants. Methods: Analysis of total fat content was carried out in several stages, namely, the red salak fruit preparation stage where the skin and flesh of the salak fruit were peeled and separated. After that, the sample was dried in an oven for 6x24 hours and ground into powder. The total fat content test stage used the Soxhlet method, where this stage produced a solution used to calculate the total fat content. Results: The results of the study showed that red salak fruit contained Negative Total Fat in both locations at different altitudes. The highest fat content in red salak fruit was obtained at 0.54995% in Negeri Buria. Meanwhile, the lowest fat content in red snake fruit was obtained at 0.52935% in Negeri Riring. Conclusion: different growing altitudes affect the total fat content in red snake fruit, where the higher the growing location, the lower the fat content, which is also supported by several internal and external factors.

Abstract

Kemacetan di ibukota DKI Jakarta tidak dapat dihindari, terutama pada titik-titik persimpangan baik di jalan-jalan protokol hingga di jalan lingkungan. Semakin hari, kemacetan di Jakarta semakin parah. Menurut sebuah penelitian, kemacetan tersebut membuat masyarakat Jakarta mengalami kerugian hingga Rp 48 triliun per tahun [1]. Dalam makalah ini akan dibahas mengenai prediksi jumlah kendaraan pada tahun 2017. Prediksi ini akan dilakukan dengan menggunakan jaringan syaraf tiruan, yaitu metode backpropagation. Metode ini digunakan karena keunggulannya dalam learning rate. Learning rate sangat berguna dalam menentukan prediksi dengan eror yang kecil. Prediksi jumlah kendaraan ini akan dilakukan pada kendaraan bermotor, mobil pribadi dan kendaraan umum. Sehingga dari hasil prdiksi ini akan dapat ditentukan langkah-langkah yang tepat untuk menekan laju pertumbuhan jumlah kendaraan. Dalam pembahasannya nanti akan digunakan Matlab 2009a.

Abstract

Moringa plant is a multipurpose plant that contains many important nutrients needed by the body such as calcium, vitamin B, vitamin A, vitamin C, protein and potassium. Based on this nutritional content, Moringa plants can be processed into vegetable products, namely buding products that are useful and nutritious. To gain acceptance regarding the preferences of consumers or the public in liking a food or beverage product, it is necessary to carry out an organoleptic test. The aim of this research was to determine the organoleptic quality of pudding products made from Moringa oleifera leaves based on variations in the addition of 100gr, 150gr and 200gr sugar. The method used is descriptive research to analyze the level of liking for pudding products. The research results showed that the organoleptic tests on pudding products made from Moringa oleifera leaves were different based on variations in the addition of 100g, 150g and 200g sugar. The variation in adding 100g of sugar shows the organoleptic results of the pudding product with a rather attractive color, slightly sweet taste, soft texture and a somewhat distinctive Moringa aroma. The variation in adding 150g of sugar shows the organoleptic results of the pudding product with a rather attractive color, sweet taste, soft texture and a somewhat distinctive Moringa aroma. The variation in adding 200g of sugar shows the organoleptic results of the pudding product with a rather attractive color, sweet taste, soft texture and a distinctive Moringa aroma.
