Abstract

Pasumpahan Island is a popular tourist destination in the Padang area. Increasing tourist activity is suspected to contribute to the degradation of the coral reef ecosystem, as observed during preliminary surveys. Coral reef degradation can significantly impact associated marine organisms, particularly megabenthos species. This study examined the association between coral life forms and megabenthos types through direct field observations. A quadrat method was applied using 5×5 m² plots across nine locations. Data analysis employed 2x2 contingency tables, and association strength was quantified using the Ochiai Index. Researchers identified six coral life forms and four megabenthos types, producing 45 potential association combinations. Results indicated that 39 combinations exhibited no association. The remaining six showed associations, equally divided between positive and negative. Positive associations occurred between mushroom corals and Acanthaster planci, massive corals and Tridacna spp., and encrusting corals and Trochus spp. These relationships were identified as commensal, where species coexist without direct harm. Negative associations were found between massive and encrusting corals, encrusting corals and Tridacna spp., and encrusting corals and Diadema setosum. The Ochiai Index proved effective in detecting species interactions and supporting coral reef ecosystem assessments.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh fortifikasi kerupuk singkong Kamang dengan tepung tulang ikan tuna (Thunnus sp.) terhadap kandungan gizinya. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima taraf perlakuan dan tiga ulangan. Data hasil pengamatan dianalisis menggunakan sidik ragam (ANOVA) dan dilanjutkan dengan uji Duncan’s New Multiple Range Test (DNMRT) pada taraf signifikansi 1%. Perlakuan dalam penelitian ini meliputi penambahan tepung tulang ikan tuna pada taraf: A (kontrol) = 0%, B = 5%, C = 10%, D = 15%, dan E = 20%. Hasil penelitian menunjukkan bahwa penambahan tepung tulang ikan tuna berpengaruh nyata terhadap kadar air, kadar abu, kadar kalsium, dan daya serap minyak, dengan nilai rata-rata kadar air sebesar 7,54–9,30%, kadar abu 8,37–14,73%, kadar kalsium 2,22–4,64%, dan daya serap minyak 1,04–6,70%. Semua perlakuan memenuhi standar mutu kerupuk sesuai SNI 0272-1991. Berdasarkan uji organoleptik, panelis lebih menyukai kerupuk singkong Kamang dengan penambahan tepung tulang ikan tuna sebanyak 5%, 10%, 15%, dan 20%.

Abstract

Nagari Kudu Gantiang is one of the nagari where most residents are engaged in agriculture and livestock farming. However, the utilization of organic waste such as crop residues and livestock manure has not been optimized. Agricultural waste is often discarded or openly burned, leading to environmental pollution, while farmers remain highly dependent on chemical fertilizers whose prices continue to increase. Based on these conditions, this community service program aimed to enhance the capacity of the women’s PKK group in processing organic waste into compost as an effort to promote sustainable agriculture. The methods included counseling, participatory discussions, and compost-making demonstrations using agricultural residues, soil, and livestock manure with the addition of EM4 bio-activator. The activity was attended by 45 participants at the Nagari Kudu Gantiang Office Hall. The results indicated an increase in participants’ knowledge and skills in composting techniques, as well as growing awareness of environmentally friendly organic waste management. This program had a positive impact by encouraging household-level composting practices, reducing dependence on chemical fertilizers, and supporting sustainable land productivity at the nagari.

Abstract

Donuts are a snack made from wheat flour and are popular among various groups. However, wheat flour contains gluten, which can cause the immune system of a person with celiac disease to react to gluten and attack the small intestine lining. Therefore, wheat flour needs to be substituted with alternative ingredients, one of which is sweet potato flour. This research aims to determine the effect of different types of sweet potato flour in making donuts on their chemical and organoleptic characteristics. The research design used was a Completely Randomized Design (CRD) with five treatments and three replications. Observation data were analyzed using ANOVA and Duncan's New Multiple Range Test (DNMRT) at α = 1%. The treatment in this study was the addition of variations of sweet potato flour (A = 50% white sweet potato, B = 50% purple sweet potato, C = 50% yellow sweet potato, D = 50% orange sweet potato, E = 50% cilembu sweet potato). Further test results showed that the addition of various variations of sweet potato flour had very significantly different effects on moisture, ash, fat, protein, carbohydrate content, and antioxidant activity. Based on organoleptic tests, the best treatment was treatment E (cilembu sweet potato flour) with an average value of 5.93 (very like), where the resulting donuts had the following chemical characteristics: moisture content (24.18%), ash content (2.10%), fat content (10.87%), protein content (14.96%), carbohydrate content (56.74%) and antioxidant activity (64.75%). Donuts with cilembu sweet potatoes have the most fragrant aroma, golden brown color, slightly sweet taste, and soft texture.

Abstract

Tujuan dari penelitian ini adalah untuk mempelajari pengaruh perbandingan susu sapi dengan susu jagung manis dengan penambahan ekstrak kulit buah naga terhadap mutu es krim dan mengetahui berapa perbandingan susu sapi dengan susu jagung manis untuk menghasilkan es krim yang memenuhi syarat SNI. Rancangan Acak Lengkap (RAL) dengan lima taraf perlakuan dan tiga kali ulangan digunakan dalam penelitian ini. Uji ANOVA dan uji lanjut DNMRT pada taraf nyata 1% digunakan untuk menganalis data hasil pengamatan. Perlakuan pada penelitian ini adalah perbandingan susu sapi dan susu jagung manis (A=100:0, B=75:25, C=50:50, D=25:75, E=0:100). Dari hasil penelitian, perbandingan penambahan susu sapi dan susu jagung manis berpengaruh sangat nyata terhadap kadar protein, kadar lemak, kadar serat kasar, total padatan, overrun, dan berpengaruh tidak nyata terhadap waktu leleh. Berdasarkan pemenuhan syarat mutu es krim SNI-01-3713-1995, sampel es krim dengan perbandingan susu sapi dan susu jagung manis pada perlakuan C sampai E memenuhi syarat, dengan kadar protein di atas 2,7% (25,69-34,86%), kadar lemak di atas 5% (9,86-14,35%), total padatan di atas 34% (38,01-47,05%), nilai overrun berada dalam skala rumah tangga 30-50% (43,21-50,04%).
