A Study on The Potency of Electrical Energy Production and Greenhouse Gas Reduction from Palm Oil Mill Effluent (Pome) (A Case Study in Lampung Province)
Get PDFIndonesia merupakan negara penghasil minyak sawit terbesar di seluruh dunia, sekaligus sebagai penghasil limbah cair pabrik kelapa sawit (LCPKS) terbesar di dunia juga. Selama ini LCPKS ditangani secara sederhana dengan sistem kolam. Hal ini menyebabkan pencemaran lingkungan seperti bau tidak sedap, mencemari sumber air, menghasilkan gas rumah kaca. Di sisi lain LCPKS meruapakan sumber energi alternatif yang potensial jika dikonversi menjadi gas methan. Tujuan makalah ini adalah melakukan analisis potensi energi yang dihasilkan dan potensi pengurangan gas rumah kaca di Provinsi Lampung. Metode yang digunakan berdasarkan servey, analisis laboratorium, dan studi pustaka yang relevan. Hasil penelitian menunjukkan bahwa jika semua LCPKS di Provinsi Lampung dikonversi menjadi gas methan akan dihasilkan energi listrik sebesar 5.41 MW dan pengurangan gas rumah kaca sebesar 242.720 ton greenhouse gas emission (CO2e). Keywords: LCPKS, GRK, gas metana, biogas

Optimasi Penggunaan Asap Cair pada Pengawetan Bakso Filler Roti
Get PDFSweet bread is a very popular food in Indonesia and the quality is largely determined by the filler used. Today, the bread is very varied filler that are the fruit aroma to chopped meatballs. The meatballs as a filler of sweet bread can only self life for no longer than 2 days, therefore it needs a preservation effort. One of technical preservation was application of liquid smoke. The research objective was to characterize of the meatballs as filler and of liquid smoke of coconut cell and to know the effect of concentration of liquid smoke to self life of sweet bread filled meatballs in storage. The results showed that dipping the meatballs in a liquid smoke was lowered taste, but only slightly affected the color, surface mucus, texture, and preference until the third day. The higher concentration of liquid smoke was the lower of total microbes in the meatball during storage. Liquid smoke was not advisable as a preservative in bread balls for sweet bread filler, because the concentration of smoke liquid 2% only decreased the bread taste.

Get PDFGaris pantai merupakan wilayah yang menjadi pembatas antara daratan dengan lautan serta mengalami perubahan morfologi dari waktu ke waktu. Wilayah ini memiliki kondisi yang sangat dinamis dimana berbagai komponen (udara, bebatuan, air) saling berhubungan. Analisis garis pantai multitemporal menjadi salah satu parameter penting untuk monitoring kawasan pantai. Informasi tersebut dapat digunakan untuk pemodelan morfodinamik, pengelolaan kawasan pesisir dan studi erosi dan akresi. Penelitian ini bertujuan untuk menganalisis perubahan garis pantai di Pesisir Utara Kabupaten Tuban, Jawa Timur menggunakan Algoritma Canny dan Citra Google Earth tahun 2000 hingga 2020. Algoritma Canny dipilih karena sudah teruji menghasilkan tepi yang tajam dan baik dibandingkan dengan algoritma deteksi tepi yang lain. Dari penelitian ini dapat disimpulkan bahwa di Pesisir Utara Kabupaten Tuban, berdasarkan sampel tahun yang diambil, garis pantai wilayah tersebut mengalami erosi sebesar 0,297 - 1,566 meter/ lima tahun. Tepi yang dihasilkan dengan algoritma Canny sangat membantu dalam proses interpretasi garis pantai dan membuat analisis menjadi lebih cepat. Kedepannya, perlu adanya elaborasi lebih mendalam mengenai penggunaan citra Google Earth dalam analisis garis pantai, khususnya pada koreksi geometriknya (Georeference). Hal ini penting untuk dilakukan karena akan mempengaruhi hasil analisis terutama posisi garis pantainya. Kata kunci: Garis Pantai, Teknik Deteksi Tepi, Algoritma Canny, Google Earth, Tuba
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
