Abstract

White moke, arak moke, red moke, tuak, and wine are the traditional alcoholic beverages of Ngada Regency. The Aimere region is home of the factories that create Moke Arak, the most popular beverage in this regency. The base ingredient for the moke prepared in Aimere district is lontar sap, as opposed to the coconut sap used in Bajawa district. This lontar sap is processed to create moke arak. Some of the factories still employ conventional techniques. One of the community's sources of income is the traditional processing of moke arak, which has been carried down from our ancestors' time to the present. The study goal is to comprehend the traditional method of creating moke arak using lontar sap and the variables that affect it. This study used a descriptive exploratory approach, gathering data using three methods: documentation, interviews, and observation. Qualitative descriptive analysis was used to examine the data. According to the study's findings, Aimere's moke arak is processed by sap gathering, fermentation, distillation, and drying. The basic material of palm sap, fermentation time, ingredient composition, temperature during fermentation and destillation, size of the distillation bamboo, and drying time are all factors that impact the manufacture of moke arak.

Abstract

Through the distribution of resources and the display of finished goods, the education expo aims to increase community and student understanding. In the So'a District, students from STIPER Flores Bajawa's Applied Biology Study Program organized an event where they displayed goods made through fermentation processing, including fruit wine. Tropical fruits such tamarillos, bananas, watermelons, oranges, and others may be found in Ngada Regency. Usually, these fruits are eaten straight away without previously being turned into food or drink items. People in the area are used to drinking alcoholic drinks including wine, beer, and moke. Other tropical fruits can be used as the foundation for wine production in addition to grapes. The purpose of this community service project is to educate the locals on how to turn tropical fruits into economically valuable wine and beverage products. In order to make wine from tamarillo, banana, watermelon, and orange, demonstration and experimental approaches were employed. Visitors to the exhibition evaluated the fruit wines based on their color, flavor, and scent. The panelists favored tamarillo wine because of its appealing dark red color, aroma of fruit and alcohol, and more delectable taste brought on by the combination of these flavors.

Abstract

Pengendalian Organisme Pengganggu Tanaman (OPT) pada kakao merupakan tantangan utama bagi petani di Desa Boba, Kecamatan Golewa Selatan, Kabupaten Ngada, yang mayoritas berprofesi sebagai petani. Serangan hama seperti penggerek buah kakao dan penyakit seperti busuk buah menyebabkan menurunnya produktivitas secara signifikan. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kapasitas petani dalam mengenali serta mengendalikan hama dan penyakit tanaman kakao melalui pendekatan partisipatif. Metode yang digunakan meliputi penyuluhan materi tentang jenis-jenis hama dan penyakit utama pada tanaman kakao, diskusi kelompok terfokus (Focus Group Discussion), serta kunjungan lapangan ke kebun petani untuk observasi langsung. Hasil kegiatan menunjukkan bahwa petani sangat antusias dan aktif terlibat dalam seluruh tahapan kegiatan. Mereka menunjukkan peningkatan pengetahuan dalam identifikasi gejala serangan dan pemilihan metode pengendalian yang sesuai, seperti sanitasi kebun, pemangkasan, serta penggunaan insektisida secara bijak. Temuan ini menunjukkan bahwa kegiatan penyuluhan berbasis praktik langsung efektif dalam meningkatkan kapasitas lokal petani dalam pengelolaan kakao secara berkelanjutan. Kegiatan ini diharapkan dapat dilanjutkan secara berkala sebagai bagian dari program revitalisasi tanaman kakao di wilayah tersebut.

Abstract

The Tamarillo fruit, commonly known as the Dutch Eggplant (Solanum betaceum), is one of the tropical fruits that thrives in the Bajawa region of Ngada Regency. However, the fruit is still consumed directly or without further processing into food or beverage products.  A study aimed at determining the effect of the concentration of tamarillo fruit on the biochemical and organoleptic characteristics of tamarillo wine. The biochemical characteristics to be measured include ethanol content, reducing sugar content, total acidity, pH, antioxidant content, as well as the number of live and dead yeast. Meanwhile, organoleptic aspects include color, clarity, aroma, taste, and the preferences of the panelists. The research method used is a completely randomized design with 3 treatments, namely the concentration of Dutch eggplant fruit: water ratios of 1:1, 1:2, and 1:3, with 3 replications for each treatment. The research results show that the wine made from starfruit with a concentration treatment of 1:3 has the highest biochemical characterization results, including ethanol content, total acidity, pH, antioxidants, viable yeast count, and dead yeast count, compared to the concentrations of 1:1 and 1:2. However, it has the lowest reducing sugar content. The organoleptic test shows that the wine with a treatment concentration of 1:3 has the highest scores for color, clarity, aroma, taste, and preference because it has a red color, clarity, fruity and alcoholic aroma, fruity and alcoholic taste, and is favored by the panelists.

Abstract

The Ngada Regency area is one of the producers of kapok bananas on Flores Island. However, there has been a decline in kapok banana production due to the attack of blood disease and fusarium wilt. Therefore, it is necessary to address this issue. Determining the effects of applying the biological agent Trichoderma sp. to control fusarium wilt disease in banana plants, comparing the effects of different banana varieties planted on farmer fields infected with the disease, and identifying banana varieties that can interact with the mixed biological agent Trichoderma sp. and organic materials to suppress fusarium wilt disease are the objectives of this study. This study used a factorial pattern Randomized Group Design (RAK) consisting of two factors, namely: Banana type factor (J) consists of 4 levels and the application of Trichoderma sp mixture (D) consists of 4 levels, namely the Banana Type factor (J), consists of 4 levels, namely: J1 = King Banana, J2 = Ambon Banana, J3 = Barangan Banana and J4 = Kepok Banana. A combination of Trichoderma sp and manure application (D) is the second element. There are four levels of this combination: D0 (no Trichoderma sp), D1 (200 gr in 4 kg of manure), D2 (200 gr in 8 kg of manure), and D3 (200 gr in 12 kg of manure). The findings demonstrated that the rate of Fusarium oxysporum wilt infection was significantly influenced by banana species. Compared to plantains and banana kepok, banana barangan and banana ambon are more resilient to the rate of infection with Fusarium wilt disease (Fusarium oxysporum). The combination dose of Trichoderma Sp with manure has a very significant effect on the intensity of Fusarium wilt disease attack (Fusarium oxysporum) and the combination of Trichoderma sp 200 grams with 4 kg of organic fertilizer is better than the other 3 doses.
