Digital Map Based Irrigation Network Profile in Kema Satu Village Kema District North Minahasa Regency

dahlan — 2024-11-25

This research uses a descriptive method by collecting data through field surveys, interviews and image analysis. The research results show that the Makansar irrigation network in Kema Satu Village consists of one main weir and three supply channels. The Makansar Satu Dam (BM I) irrigation channel is 3,129.53 ms long with a service area of 11.42 hectares. The Water Suplesi Satu (AS I) canal has a length of 1,885.36 ms and a service area of 10.22 hectares, the Water Suplesi Two irrigation canal (AS II) has a length of 544.26 and a service area of 1.77 hectares, the Water Suplesi Three irrigation canal ( AS III) has a length of 1,878.8 and a service area of 6.88 hectares. There are around 33 buildings along the irrigation canal, including 1 building, 24 tapping buildings, 7 complementary buildings, 1 tertiary box, and 1 spillway building. The condition of the network and buildings still requires a lot of technical treatment and a decline in the quality of services at the old weir, the growth of wild plants on the irrigation embankment, the presence of sedimentation and complementary buildings that are not utilized properly as water conservation efforts. The Makasar irrigation area (DI) has a P3A institution. The results of measuring the water discharge in the BM I Channel, the inflow was 0.23 m³/second and the outflow was 0.09 m³/second and the water loss was 0.14 m³/second. Measurements in the Channel (AS I) inflow were 0.07 m³/second and outflow 0.07 m³/second. Channel measurements (AS III) showed an inflow value of 0.03 m³/second and an outflow of 0.02 m³/second and water loss of 0.01 m³/second.

Modification of the DTR TETA 19 Pole Model Nutmeg Picker

demianus rossok — 2024-12-01

This study aims to modify the nutmeg harvesting tool pole model prototype 1 and test the
performance of nutmeg harvesting tool pole model that has been modified or harvesting tool
DTR TETA 19. This study uses experimental methods, tools that have been modified and then
tested to determine the performance of the tool by calculating the harvesting capacity of the
fruit/minute and also the capacity of the fruit/hour. The data obtained are arranged in
Tabular Form and analyzed descriptively. The conclusion of this study is DTR Teta 19
harvesting tool is superior to the previous tool or nutmeg harvesting tool pole model
prototype 1, where DTR Teta 19 tool has an average capacity with two harvests of 199
pieces/hour, while the harvesting capacity of the prototype 1 harvesting tool with one harvest
of 152 pieces / hour has a difference of 47 pieces (harvesting with a tool length of 200 cm).
As for harvesting with a tool length of 300 cm has a difference in harvesting capacity of 56
pieces / hour where the tool DTR TETA 19 superior. and harvesting with a tool length of 400
cm harvesting tool DTR TETA 19 is superior to the difference in harvesting capacity of fruit /
hour which is 21 pieces.

The Effect of Dehydration on Leilem Leaf Characteristics (Clerodendrum minahassae Teijsm. & Binn)

Reniaty Rombelayuk — 2025-04-14

The purpose of this study is to obtain a dehydration method that can preserve the characteristics of fresh leilem leaves. The method used in this study was a Complete Randomized Design (CRD) with 4 treatments i.e; A1 (Sunlight ±31-50⁰C), A2 (Chiller ±4-8⁰C), A3 (room temperature ±26-30⁰C), and A4 (Oven 60⁰C). Each treatment is repeated 3 times. Further research results are processed using ANOVA, if there is significount influence, it is continued with a 5% BNT test. The results showed that influence of various dehydration methods on color, water content, chlorophyll, vitamin C, and rehydration of leilem leaf. Dehydration using sunlight has an L* value of 26.63, 4,49% moisture content, 31.961 mg /L total chlorophyll, 0.027ppm vitamin C, and the rehydration ratio of 2.21. Leilem leaves dehydrated using Chiller have an L* value of 29.70, 12,60% moisture content, 45.792 mg/L total chlorophyll, 0.050 ppm vitamin C, and the rehydration ratio of 2.32. In the leilem leaf dehydration method room temperature has L* 28.67 strands, 5,54% moisture content, 41.281 mg/L total chlorophyll, 0.034 ppm vitamin C, and the rehydration ratio of 1.81. Leilem leaf dehydration using an oven has an L* value of 22.93, 3,05% moisture content, 42,132 mg/L total chlorophyll, 0.033 ppm vitamin C, and the rehydration ratio of 1.85. The best method dehydration of leilem leaves is under chiling temperature 4-8⁰C in the chiller .The physicochemical properties of leilem leaves produced are green, showing the stability of chlorophyll pigment and has the highest water absorption of rehydration ratio.
