Abstract

The objective of research was to evaluate the effect of different level of decomposers from bioethanol waste as a bioactivator to compost nutrient content. The materials used in this study were feces collected from six 3 to 5 years old of male Fresian Holstein (PFH), and decomposer agents from processed-bioethanol waste. The experimental design used was completely randomized design with four treatments and six replications, i.e. P1: 0.4% of decomposer, P2: 0.5% of decomposer, P3: 0.6% of decomposer, P4: 0.7 of decomposer %. Analysis of nutrient contents of compost was conducted at the the Laboratory of Chemistry and Soil Fertility, Department of Soil Science, Faculty of Agriculture, Gajah Mada University, Yogyakarta. Data analysis was performed using Minitab 17 software. The results of the analysis of variance showed that different levels of decomposer affected organic C, phosphor (P), Kalium (K), and Magnesium (Mg). Organic C, P, K, and Mg contents were found highest in P2, on the other hand N and Ca contents, C/N ratio, pH, and temperature of compost were not different among treatments. It could be concluded that compost made with 0.5% decomposer agents from processed-bioethanol waste was the best.

Abstract

ABSTRACTType screw water turbine is a type of water turbine which has the potential for small scale power plants, where water turbine screw type is suitable for rivers in parts of Indonesia because the operation of the turbine require only a low head turbine. With the potential of irrigation water streams at the rate of 0.3302 m3/s in Banjaran village allows the installation of the turbines type screw. In the process of designing a water turbine type screw to be optimized turbine screw to determine the value of the ratio d/D, and then calculating mechanically to determine the dimensions of the turbine blades, the turbine shaft, the transmission system (gears, pulleys and belt) as well as the power that can be produced by the turbines, by using a head of 1.05 meters. The results of this research are the technical specifications of the turbine screw with the design power of 2678.35 Watt. Performance test of the turbine was carried out in Nagrak village of Ciherang irrigation canals on Cangkuang Banjaran sub district. With variable discharge, measuring the speed of rotation of the shaft generator, the voltage and current that is produced as well as the efficiency of the turbine. From the results of testing gained 17.82 % efficiency, power turbine 531.84 Watts at discharge 0,277 m3/s.Keywords: Turbine, Head, Microhydro, OptimazedABSTRAKTurbin air tipe ulir adalah salah satu tipe turbin air yang berpotensi untuk pembangkit listrik skala kecil yang ramah lingkungan, dimana turbin air tipe ulir sangat cocok untuk sungai-sungai di wilayah Indonesia karena pengoperasian turbin ini hanya memerlukan head turbin yang rendah. Melihat potensi air aliran sungai irigasi dengan debit 0,3302 m3/s yang berada di Desa Banjaran memungkinkan pemasangan turbin tipe ulir. Pada proses perancangan turbin air tipe ulir dilakukan optimasi turbin screw dengan menentukan nilai perbandingan d/D, lalu melakukan perhitungan mekanikal untuk menentukan dimensi dari sudu turbin, poros turbin, sistem transmisi (roda gigi, puli dan belt) juga daya yang mampu dihasilkan turbin, dengan head 1,05 meter. Hasil dari penelitian ini berupa spesifikasi teknis turbin ulir dengan daya hasil rancangan sebesar 2678,35 Watt dan gambar 2 dimensi serta 3 dimensi turbin ulir hasil rancangan. Hasil perancangan kemudian direalisasikan. Untuk mengetahui kinerja turbin dilakukan pengujian yang dilaksanakan di saluran Irigasi Ciherang Desa Nagrak Kecamatan Cangkuang Banjaran. Dengan variabel ukur yaitu debit, kecepatan putaran poros generator, voltase dan arus yang dihasilkan serta efisiensi turbin. Dari hasil pengujian didapat efisiensi 17.82 %, Daya turbin 531.84 Watt pada debit 0,277 m3/s.Kata kunci: Turbin, Head, Mikrohidro, Optimasi

Abstract

Penelitian Biodiversitas Mangrove di Perairan Aceh Barat Daya Sebagai Potensi Daerah Perlindungan Laut Berbasis Masyarakat bertujuan untuk menghitung biodiversitas mangrove yang terdapat kabupaten Aceh Barat Daya sebagai salah satu wilayah yang akan dijadikan Kawasan Konservasi Perairan Daerah. Pengamatan dilakukan pada dua stasiun yakni di kecamatan Kuala Batee dan kecamatan Manggeng, Kabupaten Aceh Barat Daya. Hasil yang diperoleh menggambarkan kondisi populasi mangrove di kecamatan Kuala Batee yang kurang baik, hal tersebut ditandai dengan rendahnya nilai rata-rata kerapatan (633 ind/Ha) serta rendahnya nilai indeks keanekaragaman dan keseragaman (H=0,83 E=0,76) pada lokasi tersebut. Sementara kondisi populasi mangrove di kecamatan Manggengjuga pada kondisi yang kurang baik ditandai dengan nilai rata-rata kerapatan dalam kategori sedang (1400 ind/Ha)serta nilai indeks keanekaragaman dan keseragaman (H=0,36 E=0,53) dalam kategori rendah. Rendahnya nilaiparameter yang diperoleh disebabkan alih fungsi lahan mangrove menjadi lahan sawit dan lahan tambak. Sementara jenis mangrove yang ditemukan pada kedua stasiun pengamatan adalah jenis Ceriops decandra, Nypa fruticans, Sonneratia alba dan Acrostichum aureum dimana Sonneratia alba merupakan jenis yang ditemukan pada kedua stasiun pengamatan.

Abstract

Abstract: Abnormal Uterine Bleeding (AUB) is the most common cause of abnormal vaginal bleeding among women in reproductive age. Approximately 30% of women come to health care center with complaints of AUB during their reproductive period. The causes of AUB include a broad spectrum of diseases. The main classification of AUB according to FIGO has 9 categories of causes that is the acronym as "PALM-COEIN". This was a descriptive retrospective study using data of medical records of patients with abnormal uterine bleeding. The results showed that of: 51 cases with AUB, most were at the age of 41-50 years (24 cases; 47.06%), with the youngest age was 14 years and the oldest age was 55 years. Most of the cases had normal body mass index, multiparity, and housewife. PALM-COEIN classification showed that most were leiomyoma (29 cases; 56.86%) and ovulatory dysfuntion (11 cases; 21.57%). Conclusion: Of the 51 patients with AUB at the Obstetrics and Gynecology Department of Prof. Dr. R. D Kandou Hospital Manado from January 2013 to December 2014, most cases were aged 41-50 years, multiparity, normal BMI, leiomyoma, treatment with D & C, and the pathological tesult was hyperplasia Keywords: abnormal uterine bleeding (AUB) Abstrak: Perdarahan Uterus Abnormal (PUA) merupakan penyebab tersering perdarahan abnormal per vaginam pada masa reproduksi wanita. Sekitar 30% wanita datang ke pusat pelayanan kesehatan dengan keluhan PUA selama masa reproduktif. Penyebab terjadinya PUA mencakup spektrum yang luas dari berbagai penyakit. Klasifikasi utama yang digunakan untuk PUA berdasarkan FIGO terdapat 9 kategori penyebab yaitu akronim dari “PALM-COEIN”. Jenis penelitian ialah deskriptif retrospektif, dengan menggunakan data rekam medik pasien dengan PUA. Hasil penelitian memperlihatkan dari 51 kasus dengan PUA didapatkan paling sering pada usia 41-50 tahun sebanyak 24 kasus (47,06%), dengan usia termuda 14 tahun dan usia tertua 55 tahun. Kasus PUA terbanyak dengan Indeks Massa Tubuh normal, paritas multipara, dan pekerjaan sebagai Ibu Rumah Tangga. Klasifikasi penyebab dengan PALM-COEIN sebagian besar ialah jenis leiomioma sebanyak 29 kasus (56,86%) dan jenis ovulatory dysfuntion sebanyak 11 kasus (21,57%). Simpulan: Dari 51 kasus PUA di Bagian Obstetri dan Ginekologi RSUP Prof. R. D. Kandou Manado kurun waktu Januari 2013 sampai Desember 2014 ditemukan terbanyak pada usia 41-50 tahun, multipara, IMT normal, jenis PUA leiomioma, pengobatan D & C, dengan hasil PA hiperplasia.Kata kunci: perdarahan uterus abnormal (PUA)
