Abstract

Pengembangan mesin Computer Numerical Controller (CNC) router khusus pembuatan kerajinan produk kreatif perlu didorong untuk meningkatkan ragam dan kualitas hasil di Indonesia. Grafir batu alam (marmer, granit) secara manual dengan mengandalkan ketrampilan orang dan peralatan sederhana akan menghasilkan produk dengan waktu lama. Kompetisi dalam dunia usaha dan industri diperlukan untuk meningkatkan efektifitas dan efisiensi dengan indikator waktu pembuatan singkat, harga murah, variasi disain lebih banyak dan menarik. Tujuan penelitian untuk menemukan parameter pemesinan yang efektif dan efisien, menganalisis faktor yang berpengaruh terhadap kekasaran permukaan, dan pengkayaan ragam disain  produk kreatif bahan batu marmer. Penelitian ini menggunakan pendekatan metode eksperimen yaitu penelitian untuk menemukan  pengaruh variabel putaran spindle, kecepatan pemakanan, kedalaman pemakanan terhadap kualitas kekasaran permukaan. Hasil penelitian menemukan parameter pemesinan kecepatan potong 30 (m/min), putaran spindle 12000 (rpm), kecepatan/laju pemakanan 2000 (mm/min). Analisis faktor yang berpengaruh terhadap kekasaran permukaan grafir marmer semakin tinggi   kecepatan/laju pemakanan, kedalaman pemakanan maka semakin tinggi pula nilai kekasaran permukaan batu marmer. Aplikasi komputer dan engineering software mampu meningkatkan ragam disain produk kreatif.

Based on the result of t-test, partial total Berth Occupancy Ratio (BOR) has significant positive effect on the operational performance at Semarang Container Terminal with sig. value about 0.000 < ???? = 0.05 sig. Level and the coefficienct of 560,687 and the total Yard Occupancy Ratio (YOR) didn’t significantly affect on the operational performance at Semarang Container Terminal because it had a significant value (0.457) > sig. Level (???? = 0.05). While the Determination Coefficient (Adjusted R2) = 0.578 or 57.8%, it means that the operational performance at Semarang Container Terminal was 57,8% which was explained by Yard Occupancy Ratio (YOR) and Berth Occupancy Ratio (BOR).

Jumlahsampel dalam penelitian ini sebanyak 31 responden yang terdiri dari tiga kelompok petani, yaitupetani wortel, petani sayuran, dan petani palawija. Alat statistik yang digunakan dalammenganalisis data yang telah dikumpulkan adalah descriptive analysis, analisis uji beda, sertaanalisis servqual.Sebagian besar para petani (80%) di wilayah Selo memiliki kultur budaya yang mendukungrekonstruksi ekonomi dalam transformasi ke pertanian berbasis industri. Namun jika dilihat darisisi pertanian berbasis industri, para petani memiliki keinginan menuju ke arah tersebut namunmasih diliputi keraguan. Keraguan ini mungkin berasal dari perasaan para petani yang merasakurang memiliki pengalaman di bidang pertanian industri. Keinginan untuk merekonstruksiekonomi usaha pertanian ke pertanian industri sangat kuat namun belum mendapatkan dukungandari pihak-pihak terkait. Hal ini terlihat dari batas skor empiris minimum yang cukup tinggi(lebih dari 60%). Sedangkan dilihat dari Budaya Modern, sebagian besar petani (sekitar 70%)sangat mengetahui arti pentingnya modernisasi usaha di bidang pertanian.Hasil rata-rata skor yang didapatkan dari penelitian kali ini, antara petani wortel, petani sayuran,serta petani palawija tidak memiliki perbedaan secara signifikan. Hal ini berarti bahwa perlakuanyang diberikan kepada para petani juga tidak perlu dibeda-bedakan antar ketiga kelompok petanitersebut. Jika terdapat kebijakan dari pemerintah atau sosialisasi tentang pertanian, maka seluruhpetani diundang tanpa kecuali. Dengan demikian pembinaan dan pendampingan terhadap parapetani menjadi lebih mudah.Dari hasil analisis servqual kinerja terlihat bahwa terdapat beberapa hal yang perlu ditingkatkan,antara lain :ikatan masysrakat yang tidak menghambat atau membatasi para petani dalamberusaha di bidang pertanian. pembinaan dan pendampingan petani dalam menyelesaikanpersoalan yang dihadapi

ABSTRACTIndicator the atractions of tourism destinations with the highest score is an additional service that includes culinary, hospitality of the population, rural atmosphere, the comfort of the homestay (lodging), and the coolness of the air. The second rank of destination attractions  are both a tour package that includes outbound, river tubing, visit on location of agricultural/livestock, rabbit train and gardening. While the third is a tourist attraction that includes the art of traditional culture, the natural landscape, the local event, water activities, as well as performances of the local music. Index analysis of the competitiveness of destinations generated some indicator value, i.e. the price competitiveness indicator (PCI), infrastructure development indicator (IDI), environmental indicator (EI), technology advancement indicator (TAI), human resources indicators (HRI), as well as social development indicators (SDI). But the results of the analysis showed that each indicator is still relatively low value and needs to be improved on an ongoing basis. Keywords: Tourism destination; Tourism attractions; Tourism competitiveness ABSTRAKIndikator atraktif dari destinasi wisata dengan nilai tertinggi adalah layanan tambahan yang meliputi kuliner, keramahan penduduk, suasana pedesaan, kenyamanan homestay (penginapan), dan kesejukan udara. Peringkat kedua dari objek wisata tujuan adalah paket wisata yang mencakup outbound, river tubing, kunjungan di lokasi pertanian / peternakan, kereta kelinci dan berkebun. Sedangkan yang ketiga adalah objek wisata yang meliputi seni budaya tradisional, pemandangan alam, aktivitas lokal, aktivitas air, serta pertunjukan musik lokal. Analisis indeks daya saing tujuan menghasilkan beberapa indikator nilai, yaitu indikator daya saing harga (PCI), indikator pembangunan infrastruktur (IDI), indikator lingkungan (AMDAL), indikator kemajuan teknologi (TAI), indikator sumber daya manusia (HRI), juga sebagai indikator pembangunan sosial (SDI). Namun hasil analisis menunjukkan bahwa setiap indikator masih tergolong rendah dan perlu ditingkatkan secara berkelanjutan.  Kata kunci: Tujuan wisata; Daya tarik pariwisata; Daya saing pariwisata
