Abstract

Penelitian ini dilakukan bertujuan untuk mengetahui adanya proses pengolahan air dan pengendalian limbah di pembangkit listrik tenaga uap (PLTU) Desa Tubanan Kecamatan Kembang Kabupaten Jepara. Penelitian ini dilakukan dengan metode kepustakaan. PLTU yang dibangun di tepi laut menggunakan air laut sebagai sumber airnya. Proses yang dilakukan dalam pengolahan air ini, antara lain adalah: 1) Destilasi, 2) Demineraliasi, 3) Kondensasi, dan 4) Instalasi Pengolahan Air. Kemudian dalam melakukan pengendalian limbah PLTU dilakukan beberapa pengolahan limbah berdasarkan karakteristik dari setiap sumber limbah yang dihasilkan. Limbah PLTU sudah dapat dimanfaatkan untuk fly ash, buttom ash, dan gypsum. Dalam pengolahan limbah hasil prosduksi, PLTU juga bekerja sama dengan Perusda Pemkab Jepara. PLTU juga telah merencanakan program E-green (perusahaan hijau) yang aman terhadap manusia, lingkungan, efisiensi dalam pemanfaatan SDM, dan mampu berkonstribusi terhadap keanekaragaman hayati.[The research was conducted aimed at knowing the process of water management and waste control at the Steam Power Plant (PLTU) in Tubanan Village, Kembang District, Jepara Regency. This research was conducted using the library method. The PLTU built on the seashore uses sea water as a source of water. The processes carried out in this water treatment include: 1) Distillation, 2) Demineralization, 3) Condensation, and 4) Water Tretment plant. Then in conducting waste control, PLTU is carried out by several waste treatments based on the characteristics of each source of waste produced. The PLTU waste can already be used for fly ash, buttom ash, and gypsum. In processing production waste, the PLTU cooperates with the Regional Government of Jepara Regency. The PLTU has also planned an E-green (green company) program that is safe for humans, the environment, efficiency in utilizing human resources, and able to contribute to biodiversity.]

Abstract

Tujuan penelitian untuk mengetahui adanya pengaruh penggunaan daun inai dan kopi gula terhadap hasil uji organoleptik kutek alami meliputi kekentalan, warna dan tingkat kesukaan panelis. Penelitian ini menggunakan pendekatan kuantitatif jenis eksperiment sungguhan. Variabel bebasnya yaitu jumlah daun inai dan ekstrak kopi gula menggunakan 3 perbandingan berbeda, X1= 5 gram daun inai 5 ml kopi gula, X2= 6 gram daun inai 10 ml kopi gula serta X3= 7 gram daun inai dan 10 ml kopi gula. Variabel terikatnya yaitu sifat organoleptik yang terdapat pada percobaan. Pengumpulan data menggunakan metode kuesioner dengan Google Form sebanyak 14 panelis. Analisis data menggunakan anova tunggal. Hasil penelitian menunjukkan adanya pengaruh antara variabel bebas dan terikat ditinjau dari kekentalan dengan nilai F hitung sebesar 19,46, warna sebesar 19,22, tingkat kesukaan panelis sebesar 20,44 yang ketiganya menggunakan nilai signifikan <0,05. Dari hasil penelitian disimpulkan perbandingan X1, X2, X3 secara keseluruhan memiliki perbedaan ditinjau dari semua aspek.

Abstract

This study explored the pre-service basic science teachers’ misconceptions using a six-tier diagnostic (STD) test. This study used a cross-sectional survey research model with respondents, namely pre-service basic science teachers (PBSTs) who are first-year students. The six-tier diagnostic test consisted of three questions about change in matter (CIM), classification of matter (COM), and separation of mixtures (SOM). Each test package consists of six questions ranging from questions at the macroscopic level, microscopic communication, level of confidence, symbolic visualization to represent microscopic conditions, and self-confidence in representing concepts. The combination of answers and decisions in six-tier diagnostic includes scientific conception (SC), almost scientific conception (ASC), lack of confidence (LC), lack of knowledge (LK), misconception (MSC), have no conception (HNC). The study showed that the conceptual mastery condition is dominated by the misconceptions (MSC) category. The condition for pre-service basic science teachers’ mastery concepts having the most scientific conception category is related to changes in matter (CIM), while the condition that shows the least scientific conception category is related to material classification (COM). The results can map the conditions of mastery of the pre-service basic science teachers’ concept so that strategies can be designed to correct the emerging misconceptions.
