Abstract

PV rooftop is a renewable energy which becomes Indonesian government priority to implement in the residential and commercial buildings. However, its implementation faces a big challenge from Indonesian climate which mostly cloudy and rainy. This threat makes increasing in PV rooftop capacity, though the available rooftop area is limited. So, there is a requirement to increase the efficiency or energy output from PV rooftop. A solution which can potentially implement to do that is the use of PV bifacial. In some previous researches, PV bifacial can increase energy output of PV rooftop about 2%-12% compares to PV monofacial. However, the value of energy output from PV bifacial depends on tilt angle of PV. Tilt angle is a factor which related to latitude position of a location. Due to the most previous researches about PV bifacial are in subtropical countries, so there is a necessity to find an optimum tilt angle for PV bifacial in Indonesia. The purpose of this research is to find an optimum tilt angle and energy output of PV bifacial in several places in Indonesia. This research is a basic research so it will use simulation method using PVSyst software. PVSyst software is prominent software in PV design simulation which is already used in some previous researches. This research concludes that PV bifacial has 1o-2o optimum tilt angle difference compares to PV monofacial. The use of PV bifacial also can increase energy output 2.25%-3,5% better than PV monofacial.

Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan bantuan kepada petani rumput laut di Desa Tesabela, Kupang Barat, Kab. Kupang. Bantuan yang diberikan meliputi pembuatan konstruksi pengering para-para, melakukan penyuluhan cara penggunaannya, dan memberikan sosialisasi terkait peningkatan produktivitas dan kualitas rumput laut pasca panen. Pengering para-para mampu memberikan penjemuran rumput laut yang lebih bersih, karena rumput laut tidak diletakkan secara langsung di atas permukaan tanah. Selain itu air akan lebih mudah turun ke bawah karena menggunakan alas yang terbuat dari waring. Sehingga rumput laut hasil pengeringan memiliki kualitas yang lebih baik dan tidak berjamur. Hasil kegiatan ini memberikan pemahaman masyarakat bagaimana cara membuat pengering para-para dan cara penggunaannya secara mandiri, serta bagaimana cara meningkatkan produktivitas rumput laut serta peningkatan kualitas rumput laut pasca panen.

Abstract

The skipjack tuna fishery in NTT plays a vital role in the regional economy, therefore, a study of fishing productivity is necessary to understand the relationship between fishing effort, yield, and stock condition. This study aims to analyze skipjack tuna fishing productivity, assess the energy efficiency of local fishermen, and formulate a sustainable management strategy. The methods used were surveys and field observations, with analysis using CPUE, energy efficiency, and productivity per vessel/fisherman. Management strategies were developed using a SWOT matrix and QSPM. The results showed the highest CPUE in October–November (272.3 kg/trip), vessel productivity 6.9 kg/trip, and fisher productivity 25 kg/person/trip. The highest fuel efficiency was recorded in January (2.1 L/kg of fish). Management strategies include improving catch quality, developing business capital assistance, and renewing the Pole and line skipjack tuna fleet.

Abstract

This study aims to determine the effect of differences in the use of scad (Decapterus spp.) and scad (Sardinella spp.) bait on tuna catches using longline gear in Fisheries Management Area (WPP) 573. The research method used was a field experiment with a quantitative approach. The study was conducted over 16 fishing operations. The results showed that the use of scad bait resulted in higher tuna catches than scad bait. The average catch using scad was 1,206 kg per fishing operation, while the average catch using scad was 618 kg per fishing operation. Statistical analysis using the t-test showed a significance value of p <0.05, indicating a significant difference between the two types of bait on catches. The conclusion of this study is that scad bait is more effective in increasing tuna catches using longlines in the waters of WPP 573.

Abstract

Lubang outlet mesin polishing yang besar membutuhkan gaya pengepresan yang besar juga, gaya pengepresan yang besar ini menyebabkan tekanan yang besar pada saat proses polishing dan menyebabkan kualitas beras tidak utuh dan tidak mengkilap. Beras yang tidak utuh dan kurang mengkilap menyebabkan kualitas produksi menjadi berkurang, selain itu juga harga beras menjadi murah. Program pengabdian ini bertujuan untuk meningkatkan kualitas produksi padi pada Kelompok Tani di Desa Kebon Pedes. Program pengabdian dilakukan dengan cara memodifikasi outlet dan melakukan pengecekan kualitas padi. Hasil dari program pengabdian menunjukkan bahwasannya setelah modifikasi beras mengalami peningkatan massa sebesar 5,2%. Selain itu, beras mengalami peningkatan ukuran dari ukuran M menjadi ukuran L. Dari pengamatan visual, beras setelah modifikasi memiliki penampakan yang tidak pecah-pecah.
