Abstract

Attribute control charts especially p charts have been used widely for statistical process of atribute characteristics. In many applications, however it is neither possible nor practical to obtain sufficient subgroups io estimate accurately the control limits for the conventional p chart. This may occur when the production process is characterized as being a short run. One short run situation is a production run which produces items in a short period of time. In this article we describe the standardized p chart that the beyond control limit probabilities of proposed chart

Abstract

Research has been conducted on bioadsorbent of kepok banana peel in the form of activated carbon in reducing lead levels in Pb solution. This study aims to analyze the ability of bioadsorbent kepok banana peel in reducing lead levels in Pb solution. This research was started by making bioadsorbent of Kepok banana peel in the form of 100 mesh activated carbon and activated 2.5M H2SO4. Measurement of lead levels before and after the addition of bioadsorbent of kepok banana peel using spectrophotometric methods using AAS type UV-1800 and then analyzed using One Way ANOVA test. The results showed that the average lead level before treatment was 4.96 mg / L and after being treated with additional bioadsorbent of kepok banana peel with a variation of 1 gram, 2 gram and 3 gram in sequence of 3.76 mg / L, 0.93 mg / L and 0.22 mg / L. The biggest decrease occurred in the addition of a dose of 3 grams, namely 95.6% and the lowest in the addition of a dose of 1 gram, 24.1%. One Way ANOVA test shows the results of p

Abstract

Tujuan penelitian untuk mendapatkan gambaran partisipasi mahasiswa terhadap kebersihan lingkungan kampus Politeknik Kesehatan Surabaya. Metode penelitian bersifat deskriptif untuk memperoleh gambaran partisipasi mahasiswa terhadap kebersihan lingkungan. Populasi dalam penelitian ini adalah seluruh civitas akademik Jurusan Kesehatan Lingkungan Surabaya dan Jurusan Gizi yang masih aktif, sejumlah 389 siswa. Sampel yang diambil dengan menggunakan teknik Stratified Random Sampling, sehingga jumlah sampel diperoleh sebanyak 98 siswa. Teknik pengumpulan data melalui wawancara menggunakan kuesioner dan teknik observasi menggunakamn formulir pengamatan. Hasil penelitian menunjukkan 59 orang (60,2%) mahasiswa bersikap cukup baik terhadap kebersihan lingkungan. Kebersihan 9 ruang kelas kampus (56,25%) dikategorikan kurang bersih dan kondisi ruang kantor 8 komponen (50%) dikategorikan kurang bersih. Bentuk partisipasi mahasiswa 54 (55,1%) dikategorikan cukup aktif. Hal ini dikarenakan rutinitas pelaksanaan kegiatan Jumat Bersih setiap 2 minggu sekali. Disimpulkan bahwa partisipasi mahasiswa terhadap kebersihan lingkungan kampus cukup baik. Namun perlu dilakukan pemahaman, motivasi dan evaluasi program agar dapat ditindaklanjuti di masa yang akan datang

Abstract

Water is an important substance in life. Increased population causes increased demand for quality drinking water. Existence of safe drinking water is urgently needed. The acquisition of sun exposure data on botteld water can cause the release of chemicals that are toxic to the water that one of them is very interesting antimony to be studied. Antimony is a contaminant of drinking water that can cause acute effects and chronic effects. The purpose of this study was to determine the amount of antimony that migrated into bottled water after exposure to sunlight after 8 hours of exposure. The study included "Pre-Post Test Control Group Design". The sampling metode was simple random sampling. The data obtained were tested using anova test. Anova test results showed a significant difference after treatment. The antimony level increased 2.17 times after treatment in the sample group and 1.41 times in the control group. This is indicated that exposure to sunlight had more antimony levels contained in drinking water that’s why storage of bottled drinking water at high temperatures is not recommended. The test results also show that there is a significant difference in storage time. Keywords: bottled drinking water, antimon, polyethylene terephthalate

Abstract

There are many assumptions that the interests and motivations of students can have a big influence on the process of learning Indonesian. Interest is a beginning of the process for students when trying to get knowledge that can be used for their intended interests and goals. While motivation is an insistence on yourself to carry out an activity to reach the goal. The purpose of this study is to see the desires and efforts of students while studying. Researchers use descriptive qualitative research methods and interview techniques. Evidence from this study states that the wishes and efforts of students while carrying out the learning process are still very lacking, because in Indonesian language material, the text is used so much especially with the added lack of students' desire to carry out minimal reading activities. That way, the learning process is not only focused on students but on skills when the teacher conveys learning, so that learning activities are not monotonous and are able to focus students' focus so that they are encouraged when their learning in Indonesian takes place. This can be concluded even though Indonesian is a lesson that must be learned in each school but it is possible that there are still students who are less interested and motivated in the main lesson, namely Indonesian.
