Abstract

Koneksi matematis merupakan kemampuan yang sangat penting dan harus dimiliki karena membantu siswa mengetahui keterkaitan antara berbagai konsep baik dalam bidang matematika maupun di luar matematika dan dalam kehidupan sehari-hari. Melalui koneksi matematis, wawasan siswa akan semakin luas salah satunya pada materi bangun ruang sisi datar. Penelitian ini bertujuan untuk mendeskripsikan kemampuan koneksi matematis siswa kelas VIII  MtsN 1 Aceh Besar dalam memecahkan masalah matematika divergen. Metode penelitian yang digunakan adalah pendekatan kualitatif deskriptif. Subjek penelitian ini adalah siswa kelas VIII MtsN 1 Aceh Besar yang terdiri dari tiga siswa saja. Kriteria pemilihan subjek didasarkan pada tingkat AQ siswa (yaitu climber, camper dan quitter), melalui angket adversity quotient. Instrumen dalam penelitian ini adalah peneliti sendiri, lembar tes kemampuan koneksi matematis divergen, pedoman wawancara serta alat perekam. Pengumpulan data dilakukan dengan tes dan wawancara. Hasil penelitian ini adalah: (1) Subjek dengan kategori climber mencapai kemampuan koneksi matematis tinggi dan mampu memenuhi semua indikator koneksi matematis dalam memecahkan masalah matematika divergen. 2) Subjek dengan kategori camper mencapai kemampuan koneksi matematis sedang dan hanya mampu memenuhi 2 indikator koneksi matematis yaitu mengaitkan antar konsep matematika dalam bidang matematika dan mengaitkan antar konsep matematika dalam kehidupan sehari-hari, dalam memecahkan masalah matematika divergen (3) Subjek dengan kategori quitter mencapai kemampuan koneksi matematis rendah karena belum mampu memenuhi ketiga indikator koneksi matematis dalam memecahkan masalah matematika divergen pada tahap menyusun rencana, melaksanakan rencana dan memeriksa kembali.

Abstract

This research uses a descriptive analysis method with a qualitative approach. The aim of this research is to obtain feasibility recommendation for the Municipal Waterworks (PDAM) of Bengkalis’ drainage to be functioned as a forebay. The feasibility recommendation will be obtained through comparing the observation results of measurement on the width, length, and height of standing water on the drainage of the reservoir to the calculation results. The result of this research shows that the width of drainage based on observation is 1,85m, with the calculation of 1,72m, gap of 0,13m, and length of drainage based on observation is 6,85m, calculation of 6,63m, gap of 0,22m length of head based on observation of 0,58m, calculation of 0,68m, gap of -0,10m with turbine output of 1,74Kw, power output of 1,53Kw and generator power capacity of 1,69Kw, and with simulating the height of standing water of 0,53m dan 0,48m, results turbine output of 1,59Kw dan 1,44Kw, power output of 1,40Kw and 1,27Kw and the generator power capacity of 1,54Kw dan 1,40Kw. It can be concluded that the drainage of Bengkalis PDAM’s reservoir can be functioned and feasible to be implemented as a forebay of Micro Hydro Power Plant (PLTMH).   Keywords : PLTMH, Forebay, Drainage, Reservoir, Power

Abstract

This study explores a community empowerment model in the Teluk Pangpang area, Banyuwangi, using the Pentagon Asset approach, focused on mangrove management. The Pentagon Asset encompasses five key elements: human, natural, physical, financial, and social assets, which are analyzed in-depth to identify the potential and challenges in improving the welfare of coastal communities. Teluk Pangpang, with its rich and diverse mangrove ecosystem, offers significant economic opportunities through the development of ecotourism, silvofishery, and other conservation practices. This research formulates an adaptive and contextual empowerment model that integrates environmental conservation with local economic development. The study's findings indicate that optimizing the pentagon assets can enhance community participation, strengthen social networks, and create sustainable mangrove management mechanisms. These findings provide valuable insights for the development of effective natural resource management strategies while supporting economic improvement for coastal communities in Teluk Pangpang and similar regions.

Abstract

This research aims to synergize local microorganisms (LMO) of golden snails (Pomacea canaliculata) and seed age in optimizing rice seed germination (Oryza sativa L.). Golden snail LMO, which is rich in organic nutrients and beneficial microorganisms, has the potential to improve seed quality and viability. The study used a factorial randomized block design (RBD) with two factors: golden snail LMO concentration (Control, 20 ml/L water, 40 ml/L water) and seedling age (7 days, 11 days, and 15 days after sowing). The variables observed included seed germination, simultaneity grows and growth speed. The results showed that the golden snail LMO concentration of 20 ml/L and seed age of 11 days after sowing gave the highest results for the observed variables, namely seed germination and growth speed while the interaction between golden snail LMO concentration mas 40 ml/L and seed age of 15 days after sowing gave the highest results for the variable observing growth synchrony. The combination of the two factors showed a positive interaction that supported the germination process effectively. This study concludes that the use of golden snail LMO and selecting the right seed age can be an ecological and efficient approach to increasing rice seed productivity, supporting sustainable agriculture.

Abstract

This study aims to determine the effect of using Lactic Acid Bacteria (LAB) isolates on the fermentation process of mucuna-based compost. The parameters observed included temperature, pH, color, aroma, and texture for 27 days of fermentation. The results showed that LAB treatment had a significant effect on the acceleration and quality of fermentation results. The temperature increased faster and remained within the optimal range of microbial activity (22–55°C). The pH value decreased in the early fermentation phase due to the production of organic acids, then returned to being stable approaching neutral at the end of fermentation. The color change towards blackish brown occurred faster in the LAB treatment, indicating earlier compost maturity than the control. The odorless aroma appeared earlier (day 9) in the LAB treatment compared to the control (day 12), and the texture became smoother faster. Overall, the use of LAB isolates was proven to accelerate the decomposition process of mucuna organic materials, increase microorganism activity, and produce compost with better quality than without LAB treatment.
