Abstract

Perkembangan teknologi yang semakin maju dan pesatnya kondisi pasar industri menutut perusahaan untuk mampu memberikan kepuasan kepada konsumen, dengan cara memberikan produk yang sesuai dengan standar kualitas. Salah satu hal yang harus dilakukan untuk mengurangi cacat pada produk adalah melakukan pengendalian kualitas. Dengan adanya pelaksanaan pengendalian diharapkan menjamin tercapainya sasaran jangka pendek maupun jangka panjang yang telah ditetapkan perusahaan. Perusahaan dituntut untuk memperhatikan produk yang dihasilkan, di antaranya dengan memberikan perhatian pada kualitas produk. Untuk meminimalisir terjadinya produk dengan kualitas yang kurang baik. Maka dilakukan kegiatan dengan menggunakan metode Quality Control Circle (QCC). Metode analisis yang dilakukan adalah dengan menggunakan diagram fishbone. Dengan kegiatan yang dilakukan diharapkan perbaikan kualitas akan terus berlangsung, dan kualitas semakin membaik. Untuk meminimalisir terjadinya pembuatan barang yang kurang berkualitas pihak perusahaan mewajibkan setiap operator untuk menjaga 3M (Tidak menerima, Tidak membuat, Tidak meneruskan). Selain itu jika terjadi upnormal pada saat proses berlansung, maka operator diharuskan untuk melakukan tindakan Stop, Call, Wait (SCW).

Abstract

Telah dilakukan penelitian mengenai penggunaan biomasa jamur Pleurotus ostreatus dalam penyerapan logam krom dari larutan limbah cair penyamakan kulit melalui proses biosorpsi. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan biomassa yang berbeda-beda terhadap kapasitas biosorpsi logam krom oleh jamur Pleurotus ostreatus pada limbah cair penyamakan kulit. Parameter yang diukur yaitu banyaknya serapan ion logam (q) untuk tiap gram biomassa yang digunakan. Enam variasi biomassa kering dari jamur Pleurotus ostreatus yaitu (0,04) g; (0,08) g; (0,12) g; (0,16) g; (0,20) g; (0,24) g dalam bentuk serbuk dicampurkan kedalam 0,25 L larutan limbah penyamakan kulit. Untuk pH larutan diatur hingga pH 5 dan waktu kontak penelitian yang digunakan adalah 80 menit berdasarkan hasil pra-penelitian. Konsentrasi larutan krom sebelum dan setelah perlakuan ditentukan dengan metoda AAS (Atomic Absorption Spectrometry). Konsentrasi logam krom sebelum perlakuan adalah 297,5 mg/L dan setelah proses pengontakan dengan biomassa jamur Pleurotus ostreatus kadar logam krom dalam larutan limbah dapat terserap hingga kisaran 73%- 80%. Serapan ion logam tertinggi terjadi pada biomassa perlakuan 0,04 gram yaitu sebesar 148,83 ± 2,58 mg/g dan terendah pada biomassa perlakuan 0,24 gram yaitu sebesar 22,75 ± 0,62 mg/g. Kapasitas biosorpsi maksimum dari jamur tiram putih (Pleurotus ostreatus) terjadi pada konsentrasi biomassa yang rendah dan mengalami penurunan seiring dengan peningkatan kosentrasi biomassa yang digunakan.

Abstract

A study on the profile of the continuous professional development (CPD) program of biology teacher in West Java has been done descriptively since March until November 2010. The study was aimed to obtain several information about professional activities have been being followed by biology teachers in West Java. This information was then used to draw CPD profile conducted by biology teachers in an effort to enhance their competencies and their professional quality. Respondents of the study were biology teachers qualified to follow teacher certification and employing in senior high schools of 11 cities in West Java. Information about perceptions of the teacher on teacher improvement programs, the forms of the professional activities of the teacher and the sources supporting the teacher to follow those activities were collected using questionaire. The result shown that biology teachers in West Java had good perception on improving the quality of the teacher and there are eight forms of professional activity which were followed by biology teachers in West Java in an effort to enhance their own professional quality. The seven forms of professional activities were Education and Training (Diklat), Workshop, Seminar, writing teaching material, visiting scientific institutions, doing research, writing and publishing article and/or a textbook. Three out of those seven forms of professional activity had high teacher involvement scale, which indicated that they were preferred by biology teacher. The three forms professional activities were Education and Training, Seminar, and Workshop. However, the number of each professional activity followed by teacher in the last three years was very low (less than one activity each year) due to several reasons. The four main reasons were no permission from school principal interconnecting with teacher task in the school, distance to the place of professional activities, financial, and teacher family.

Abstract

In the current era of globalization, the need for Information Technology is indispensable as a support for business processes, so that with the support of this Information Technology, it will further develop the business that is run. One of the growing lodging businesses is Homestay Wisma Sarang Badak, which is located at Ujung Kulon Pandeglang National Park, Banten-Indonesia. There is still a lack of facilities and infrastructure to support this homestay, especially the limitations of information system-based technology media which have only relied on conventional recording in this case regarding room reservations. From the results of these observations, the idea emerged to research that place. Namely by building a Web-based room reservation information system. To build a room reservation information system, researchers use UML (Unified Modeling Language) as a design tool and use PHP and MySql programming languages as databases. As a result, it is hoped that with this information system, it can make it easier for customers to make room reservations. In addition, Homestay Wisma Sarang Badak can be widely known by the public. And then it can increase the number of customers and can increase income for managers.
