Abstract

The conversion of a Ro-Ro Vehicle Carrier into a Ro-Ro Passenger Ship. in compliance with PERMEN RI Number PM 62 of 2019. necessitates the use of at least two main engines. This study evaluates the performance of the C5-75 and MAU4-65 propellers to assess their efficiency. At a speed of 21 knots. the C5-75 propeller achieves an efficiency (ŋ) of 0.66 in clean hull conditions and 0.655 in rough hull conditions. The MAU4-65 propeller shows an efficiency of 0.646 in clean hull conditions and 0.653 in rough hull conditions. The Engine Propeller Matching (EPM) only a 12640 kW main engine indicates optimal operation at 109 rpm (clean hull) and 112 rpm (rough hull). Added 2 auxiliary main engine 1040 kW engines operate at 1577 rpm (clean hull) and 1597 rpm (rough hull). These findings highlight the propeller's performance and the required engine settings to achieve the desired speed after conversion.

Abstract

Pelatihan digital marketing pada dua puluh lima ibu rumah tangga anggota paguyuban Pos Pendidikan Anak Usia Dini (PAUD) Terpadu (PPT) Tunas Mulia Keputih Surabaya perlu dievaluasi untuk melihat tingkat pemahaman peserta setelah diberikan pelatihan. Tujuan penelitian ini untuk melihat perubahan tingkat pemahaman peserta terhadap materi pelatihan setelah diberikan pelatihan serta melihat perbedaan rerata dari nilai pre-test dan post-test. Peserta diberikan pre-test dan post-test sebagai langkah awal untuk melihat efektivitas pelatihan. Nilai pre-test dan post-test diuji dengan wilcoxon signed rank test untuk melihat perbedaan rerata setelah sebelumnya dilakukan uji normalitas. Berdasarkan uji normalitas dengan shapiro wilk, diperoleh nilai p-value kurang dari 0.05 sehingga disimpulkan nilai pre-test dan post-test tidak berdistribusi normal. Nilai rata-rata post-test mengalami kenaikan sebesar 5.11% dari nilai rata-rata pre-test yang mengindikasikan ada peningkatan pemahaman peserta setelah diberikan pelatihan. Berdasarkan uji wilcoxon signed rank test memberikan hasil bahwa nilai p-value lebih dari 0.05 sehingga disimpulkan tidak terdapat perbedaan signifikan terhadap nilai rerata peserta baik sebelum dan setelah diberikan pelatihan.

Abstract

The urgency of this research lies in the need to strengthen institutional capacity as a prerequisite for enhancing the productivity and competitiveness of maize farmers, and as a collective instrument to address market and policy dynamics. This study aims to identify internal and external factors, as well as to determine appropriate strategies for institutional strengthening of the Padang Roppo Farmer Group in Tallu Bamba Village, Enrekang Sub-district, Enrekang Regency. A qualitative approach with descriptive analysis was applied, using purposive sampling to select 16 informants. Data were obtained from both primary and secondary sources through observation, interviews, and documentation. The results indicate that internal factors consist of five strengths and three weaknesses (total score: 3.46), while external factors consist of three opportunities and two threats (total score: 3.53). The IE matrix places the group in Quadrant I (“grow and build”), and SWOT analysis produces four alternative strategies: SO, WO, ST, and WT. The findings suggest the need for local government intervention through sustainable institutional empowerment programs, financing facilitation, and integration of institutional development with maize commodity programs at the village level.

Abstract

This study aims to analyze the potential utilization and economic valuation of mangrove forest ecosystems. This study was conducted in Manyampa Village, Ujung Loe District, Bulukumba Regency, South Sulawesi Province. Samples were selected using a purposive sampling method, involving 20 pond fish farmers, 20 crab catchers, and 20 tourists. The study employed both descriptive quantitative and qualitative data analysis methods. This study indicates that the mangrove forest in Manyampa Village covers 27 hectares; however, only 7 hectares are currently utilized. Direct benefits such as mangrove fruits, wood products, and protective functions against abrasion, storm surges, and saltwater intrusion. Indirect benefits such as fish-shrimp-crab habitat, nutrient sources, environmental education, and ecotourism. The direct benefit value of the economic valuation of the mangrove ecosystem is IDR 4,562,963,185.00 per hectare per year. The indirect benefit value from milkfish (bandeng) cultivation in ponds is estimated at IDR 741,925,000.00 per hectare per year, and the value of coastal fishermen's catch is IDR 11,910,000.00 per hectare per year. The economic value of ecotourism in the mangrove forest ecosystem is estimated at IDR 89,250,000 per hectare per year. The mangrove forest ecosystem in Manyampa Village has an estimated economic value of IDR 5,406,048,185 per hectare per year. Given the total area of 27 hectares, the overall annual economic value of the mangrove forest is approximately IDR 145,963,300,995.

Abstract

Salah satu cara untuk meningkatkan performa motor yaitu mengganti TPS standart dengan racing berbahan bakar Pertalite dan Shell V-Power. Penelitian ini bertujuan untuk mengamati pengaruhnya terhadap torsi, daya, BEMP, FC, SFC, dan efisiensi thermal pada engine Vario 125. Data dikumpulkan melalui dua pengujian pertama dengan bahan bakar Pertalite menggunakan sensor TPS standar dan racing, dan kedua dengan bahan bakar Shell V-Power menggunakan alat dynotest, tachometer, dan buret. Hasil penelitian menunjukkan bahwa penggunaan sensor TPS standartdan racing dengan bahan bakar Pertalite dan Shell V-Power memiliki pengaruh nyata terhadap performa mesin. Torsi maksimum dicapai pada putaran 3000 RPM, dengan sensor TPS racing berbahan bakar Pertalite sebesar 19,15 Nm. Daya maksimum didapatkan dari penggunaan sensor TPS standart berbahan bakar Shell V-Power yaitu 9,5 HP pada putaran 8000 RPM. Tekanan efektif rata-rata maksimum didapatkan pada putaran 3000rpm yaitu 19,440 kgf/cm2. Nilai FC dan SFC paling rendah tercapai saat menggunakan sensor TPS standart dengan bahan bakar Shell V-Power, dengan nilai masing-masing 0,18 kg/jam dan 0,026 kg/HP.jam pada putaran 2000 RPM. Untuk nilai efisiensi thermal maksimumnya sebesar 53,42% terdapat pada putaran 3000 RPM.
