Abstract

Tofu is the main protein source of Indonesian food. It is cheap but high quality of nutrition content. This food is usually preserved by toxic chemical, formalin. This experiment observed if natural product may be efficiently used as tofu natural preservation. Several leave extracts has been tested as tofu preservation. These are, mimba (Azadirachta indica L.), mengkudu (Morinda citrifolia L.), and sambiloto (Andrographis paniculata). All of these leave extracts has been known contain antibacterial compound. The aim of this research was to study the efficiency of these three leave extract for tofu preservation. Tofu were soaked at difference concentration of leave extracts of 50%, 25%, and 12,5%. As a result extract mimba is the most effective preservation for tofu. The most effective concentration for tofu preservation of mimba extract was 5%.

Abstract

The crop of rosella (Hibiscus sabdariffa var.Sabdariffa) known as medicienal crop and fiber producting crop. Last research was known as pulp. Growth of stem fiber are influenced by environmental factors. The aim of this research is to know the development of stem fiber is treated with different shading and volumes of water sprinkler. Factorial completely randomized design (RCD) was used in this research. The first factor was three levels of shading (I0: 0%, I1: 55%, I2:75%) while the second factor was three levels volumes of watering sprinkler (P1: 240 mL, P2: 480 mL, P3: 720 mL). The observed variable was total, diameter and long of rosella stem fiber cell. Collected data were analysed using Analysis of Variance (ANOVA) followed by Duncan’s Multiply Range Test (DMRT). The result of this research indicate that there are influence interaction shading and volum water sprinkler to rosella stem fiber development. Shading treatment at all volums of water sprinkler have an effect on to improve the length and diameter cell fiber, without shading treatment with volum of water sprinkler at soil field capacity of improve the amount of fiber cell.

Abstract

Masyarakat Kedungbanteng memanfaatkan Waduk Cacaban sebagai tempat kegiatan wirausaha. Masyarakat bergerak dalam bidang sektor informal karena dalam wilayah tersebut dimungkinkan hanya bermodalkan ketrampilan dan pendidikan yang minim. Tujuan penelitian ini adalah untuk menganalisis profil dan aktivitas pedagang di Waduk Cacaban yang sering tanpa ijin pemerintah. Penelitian dilakukan dengan observasi mendalam dan wawancara. Hasil penelitian menunjukkan masyarakat Kedungbanteng berdagang di Waduk Cacaban karena suatu anggapan bahwa Waduk Cacaban merupakan tanah warisan nenek moyang yang digunakan untuk tujuan kesejahteraan hidup mereka. Oleh karena itu, masyarakat merasa tidak memerlukan ijin resmi dari pihak pengelola Waduk ketika mereka membuka tempat usaha di waduk tersebut. Ketika petugas menertibkan keberadaan para pedagang, terkadang mereka tidak mengindahkan hal tersebut. Karena anggapan tersebut, ada pula keyakinan kalau ada orang dari luar daerah Kedungbanteng yang berjualan di tempat tersebut, usahanya tidak lancar dan akhirnya harus gulung tikar. Hal tersebut menujukan adanya kekuatan budaya dalam masyarakat bahwa Waduk Cacaban merupakan sebuah tempat yang diwariskan nenek moyang mereka khusus untuk masyarakat Kedungbanteng.Kedungbanteng community makes Cacaban Dam as a place of entrepreneurial activity. The community is engaged in informal sector where they only need minimal skills and education. The purpose of this study is to analyze the profile and activity in of merchants in Cacaban Dam who often do business without government approval.

Abstract

Telur merupakan salah satu bahan pangan sumber protein yang banyak dikonsumsi oleh masyarakat yang juga memiliki potensi bisa membahayakan kesehatan dimana telur ayam ini merupakan salah satu kontaminasi bakteri Salmonella sp. yang dapat menyebabkan penyakit melalui makanan/minuman. Tujuan penelitian ini adalah untuk mengetahui kandungan bakteri Salmonella sp. pada minuman Susu Telur Madu Jahe (STMJ) yang dijual di warung minuman taman Kota Damay kecamatan Kota Selatan kota Gorontalo. Penelitian ini merupakan penelitian deskriptif, dengan populasi 8 orang, sehingga sampel merupakan seluruh dari populasi. Hasil yang diperoleh akan dianalisis secara deskriptif dan disajikan dalam bentuk table distribusi frekuensi dan dinarasikan dengan kepustakaan yang relevan. Hasil penelitian ini menunjukkan bahwa 7 sampel (87,5 %) dari 8 sampel yang diperiksa dengan media Salmonella Shigella Agar (SSA) terlihat adanya pertumbuhan bakteri. Setelah diamati lebih teliti lagi dengan melihat ciri dari Salmonella sp. yaitu bening sampai buram dengan bintik hitam di tengah maka hasil akhir seluruh sampel tidak mengandung Salmonella sp., tetapi tidak terbebas sama sekali dari kuman lain yang kemungkinan bisa bersifat patogen. Berdasarkan hasil penelitian di atas maka saran yang dapat diberikan kepada pedagang adalah lebih meningkatkan lagi hygiene dan sanitasi dalam pengolahan minuman Susu Telur Madu Jahe (STMJ) untuk mewaspadai adanya kontaminasi Salmonella sp. Kata kunci : Minuman Susu Telur Madu Jahe (STMJ), Bakteri Salmonella sp.

Abstract

This study aims to make a morphological identification of the rumen contents of moles given a different source of glucose as an energy supply for microorganisms contained in Mol solution. In the process of making moles, it is also compared to aerobically and anaerobically. There are six types of moles which are made from the contents of the rumen with different compositions, namely: 1. Rumen contents + molasses + tofu water anaerobically, 2. Rumen liquid + molasses + soaked soybean aerobically, 3.1 rumen content + rice water + molasses an aerobically, 4. Fill the rumen + sugar + soybean water. The four mixtures of local microorganisms were incubated for 7 days. The results of the microbial identification observations were discussed descriptively. Based on the results of microbial identification, there are types of bacteria bacillus sp, and the fungus Candida sp.

Abstract

Currently, the development of acne drugs (antiacne) use  many natural materials because the natural materials can minimize the side effect if compared with synthetic chemicals drugs. Acne can caused by propionibacterium acnes, staphylococcus epidermis and staphylococcus aureu. One of plants that can be used for acne treatment is leaves of Avocado (Persea americana Mill). The aim of this study was to know whether the ethanol extract of leaves of avocado (Persea americana Mill.) can be made into an ointment preparations that fulfill the requirements. Sample in this research was extract of avocado leaves which used maceration method. The ointment formulations were made into some variation concentrations of PEG 400 and PEG 4000: Formula I (30%:70%); Formula II (50%:50%) and Formula III (70%:30%). The results show that the ointment of avocado leaves which fulfilled the requirements of physical properties is formula III with concentration of PEG 400 70 % and PEG 4000 30 %
